HARVESTING MACHINE WITH BRINGING IN ACTION TWO HYDRAULIC ELEMENTS MACHINE ON THE BASIS OF MOVEMENT OF ONE PART RELATIVE TO THE OTHER MACHINE

TECHNICAL FIELD OF THE INVENTION

The invention relates to harvesting machine with bringing in action two hydraulic elements machine on base displacement of one part of machine relative to the other.

Machine can be machine hitching type with possibility of actuation of the hydraulic elements, based on hydraulic circuits with limited supply on tractor.

Machine can contain cutting bar and converging components for formation of of roll or can contain other interacting with the agricultural culture of members, such as tilter or coupler rolls.

BACKGROUND OF THE INVENTION

Harvest machine hitching type, as a rule, buksiruyutsya tractor by means of lever coupling apparatus, which requires angle control relative to frame of machine for precise control movements and more coarse movement in transportation position.

From some machines required follow the tractor only in one direction, and, respectively, they contain lever coupling apparatus, which is located on one end of the machine. In other, for which the proposed invention especially effective, lever coupling apparatus with tractor continues from frame above the reaper to coupling compound and may rotate working cylinder with one side of the reaper on other so, to header could be located shoulder with tractor in one side or in a whole symmetrically in the other side of the.

Trailing machine given type of well known and exists multiple different examples, performed near various companies.

Proposed invention in first turn relates to disk reapers, other known, as rotary mower, for which structure especially suitable. However, the same configuration can use other types of binding, including riper with enclosure-fold cutting apparatus, where as a rule is winder for controlling movement of agricultural crops to cutting knife.

Proposed invention mainly relates to reapers, which are used central pole or lever coupling apparatus, which may rotate in both sides from central line, including transportation position at right angles to the central line. Machine with central journal uses turning cylinder for direction of machine from one field position to the other, at that maximum permissible turn is regulated or stoppers of cylinder, or separate mechanical stoppers between coupling device and rear frame. At field operation operator usually controls handlebar from one stop to the other, therefore there is no necessity in very fine adjustment of its position with the use of cylinders. For help in retaining resistance machine angles turns usually are of the order of or slightly less than, than in 45 degrees in each side from the central line.

However same configuration may be used in other types of binding, including reaper, where lever clutch device is located on one end of and usually is fixed during normal operation, but can rotate in the transportation position at right angles to the central line.

Are known and are widely used disk reaper, which are used as cutting system of multiple separated by gaps of discs along the width of header, each disk rotates around appropriate vertical axis.

Disk reaper contain supporting frame with main back beam, supported by on a pair of separated by gap running wheels with cutting bar and plyushchilnoi system, suspended on frame.

Often similar disk reaper are relatively narrow in width field, for example, 12 feet or 16 feet, so that transportation is performed simply by displacement of central draft pole in position directly forward so, to drag header directly behind tractor. This is accepted in many countries even at width reaper all is more than acceptable width of road. However official requirements to towing machines on roads become more rigid, and users with become all more aware about risks towing sverkhshirokogo equipment. Also exists all more povyshayushcheesya requirement provide machines of larger width, which probable becomes more an important at due solution of problem of transportation.

Due to this, some manufacturers provide trailer, which provides for maintaining reaper on trailer in direction, transverse to direction field forward, having in form, that transverse width reaper, as a rule, is permissible transport width. However trailers are undesirable because of the fact, that the trailer is additional equipment, which must be to acquire, by, that trailer it is necessary to tow with place on place and, due to this, it may often be in improper place or be not immediately available, increasing respectively transportation time.

Due to this, in Europe, where requirements to transportation are more rigid, h- asto attempted to provide on harvester of shipping wheels, which can turn on ground, providing possibility of towing reaper on transportation wheels in transverse direction.

Provision of transporting system on harvester require use of additional hydraulic circuits for controlling production scanning cylinders, system of frame lifting for running wheels and steering control of the coupling apparatus. However, on the many tractors are limited by device for controlling supply of fluid medium.

DESCRIPTION OF PREFERRED EMBODIMENT

INVENTION

On Figure 1 is sweeping machine hitching type, in other words in whole position of 10, for attachment to coupling device 9 of tractor (not shown) by means of adhesion compound, depicted shown and the designated in whole position of 11. Shown machine for harvesting agricultural crops relates to the type, is cutting system 4, containing a row of disks 7, installed on cutting bar 6 as shown on Figure 5. Respectively each disk 7 is installed on cutting bar 6 with possibility of rotation around its its own vertical axis 5 with separated gaps along axis positions width of cutting bar.

Each disk carries blade with placement on 180° so, to one disk stirred with shift in phase 90° relative to the next disk, respectively providing possibility of overlapping cutting action blades. Configuration of given type of well are known, and in the previous level of equipment can be find multiple examples. Cutting bar Figure 5 is installed on the frame substantially marked with position 12Α , containing continuing forward side supporting members 12V. Disks are closed body, substantially denoted position of 13, so that cutting system is for safety is closed.

Behind cutting bar 6 is crusher 2, which can-to row of various types, including machine with bichevym vehicle. In a back part behind outlet hole 9 is provided screen 8. It can act only for in the formation of roll or in with respect to plyushchilki with bichevym vehicle can form obstacle for preventing high speed of unloading of material, which may strike in surrounding people or objects, causing damage.

Frame 12Α reaper is mounted on support frame, containing main rear beam 12 across rear part of reaper, which continues in cross direction td along width of device to pair of posts 15 and 16, which hangs down with transverse beam 12, maintaining pair of wheels 17 and 18, which carry frame in moving along the ground in field or in working position. Wheels 17, 18 are installed in forward direction along direction fd forward field at right angles to direction td.

Wheels can be adjusted in height by means of cylinders 17α, 18Α with limited adjusting movement of only for height adjustment of frame from ground for field of operation and with more large motion in one direction for lifting frame relative to running wheels on height for deployment of transporting system, described further, in other direction for lowering the frame on transport system and for lifting the running wheels, when transportation system is in its place.

Cutting bar 6 and associated components, including universally recognized plyushchilnuyu system frame reaper 12Α , are supported on main beam 12 by means of suspension system, marked with substantially position 14, containing lower support 14c, which allows cutting brusu float relative to the beam 12 for support on ground, at that height of beams 12 is adjusted for pressure control on ground on the side of the cutting bar well known way. Angle reaper on frame can be adjusted by means of optional cylinders 14α, which make header turn around horizontal axis. This adjustment may be is excluded and is replaced by simple coupling device, if tractor not carries sufficiently hydraulic circuits for maintaining current function.

Lever 19 coupling apparatus attached to transverse beam 12 mounting bracket 20, connected from the top of beam 12.

In shown embodiment of bracket 20 is located in the center of the beams 12 so, to lever 19 coupling apparatus can turn around vertical hinge finger 20Α in one side (Φig. 1) or in the other side of the (Figure 2) under control of the cylinder 21. Should be to take into account, that displacement of lever 19 clutch device in one direction causes transporting harvesting machine shoulder in one side of the tractor, and rotary displacement of lever 19 adhesion device in the other side of the tows sweeper machine shoulder in opposite direction. Lever coupling apparatus can also be is positioned in the center, in which case of sweeping machine is towed by directly behind tractor usually in transit position. Also in some cases for control of accurate movement reaper behind tractor for installation position reaper across rear part of tractor can be used cylinder 21, which is used for moving to transport facility, as described further.

Reduced above configuration disk mower hitching type well known and in the previous level of equipment can be find multiple examples, including multiple patents of authors present application, on which can be made reference along additional parts, not described in the given document.

In given configuration is additional transportation device 30, attached to beam 12, which, essentially, it provides the possibility of lifting the reaper for breaking field running wheels 17, 18 from ground and for maintaining reaper on transportation running wheels 31 and 32 for movement in transverse direction td frame 12Α and contained on it of blade system 4, towed tractor by means of link 19 coupling apparatus.

As described earlier, in field position of lever 19 coupling apparatus continues from frame substantially forward for towing machine in direction fd forward. In transit position lever coupling apparatus is turned so, that it lasted from one end 12c of frame substantially in transverse direction td for towing machine in lateral direction.

Transportation unit 30 has two transportation drive wheels 31 and 32, attached lower frame 33 to rear main beam 12 of frame 12Α for engagement with ground, oriented in direction of transportation and supporting frame 12Α and header during transportation.

Substantially, shipping running wheels 31, 32 may move between field position, indicated on Φig. 1 and 2, and as a position, indicated on Figure 4 and in field position, shipping running wheels, torn-away from ground for field operation, are supported at lower frame 33. Lower frame and wheel 31, 32 carries main beam 12, so that load from reaper are transferred by means of the existing structure, developed for transfer of loads.

Main beam 12 carries lower frame and wheel 31, 32 so, so that they continued upwards and backwards from main beams.

So, entire transportation system is maintained in field position in location, where transportation system does not hinder agricultural culture or in front of the reaper during mowing or during displacement of agricultural crops through header after mowing, or in roll, laid down on the ground after treatment.

In transit position, shipping running wheels 31, 32 are in contact with ground, at that field running wheels 17, 18 lifted from ground. So, field running wheels not during transportation and, respectively, remain unchanged compared to their in the usual effect and with the same orientation relative to machine. No demand nor in provision of adjustment with increased height, nor in provision of rotating support, which changes orientation.

Substantially, transportation unit 30 is made with possibility of lifting frame 12Α and blade system 5 by means of lowering of running wheels 31, 32 on ground and, respectively, lifting frame and cutting bar on height, on which one of the transportation running wheels 32 may pass under cutter system in position in front of the cutting bar 6 and under screens 13. I.e. frame and blade system are lifted by means of downward movement of transportation running wheels 31, 32 in position, prescribed on figs. 3, where wheels roll along the ground under main beam 12, to raise main beam in point, where running wheels 17, 18 are torn off from ground.

Shipping running wheels 31, 32 are contained on common unit 33 lower frame, connected to beam 12 of frame 12Α , so that both transportation drive wheels are installed between field running wheels 17 and 18, substantially, in the center of the beams 12.

Lower frame 33, substantially, g-shaped with post ZZA , which is vertical in position of figs. 3, and horizontal beam 33V. Wheel 31 is positioned close to lower part of tine ZZA with wheel 32 on the opposite end of beam 33V. Post ZZA is formed from two parallel elements for stability.

In transit position transportation running wheel 32 is in the position with front side of line COGL (Figure 5), parallel to transverse direction td, containing center of gravity of the machine, and transportation running wheel 31 is in the position on rear side of line COGL.

Transportation running wheel 32 moves in its position with front side of line COGL by passage of under knife system of 4.

Shipping running wheels 31, 32 are contained on common unit 33 lower frame, connected to beam 12, with the upper end of post ZZA unit 33 lower frame is mounted with possibility of rotary displacement around horizontal hinged finger ZZS , forming the axis of rotation, parallel beam of 12 for lowering transportation running wheels on the ground and lifting field running wheels. Movement of lower frame 33 around axis of finger ZZS is cylinder 33D.

Hinge finger ZZS is contained on rotary support 35, which is connected with frame for rotary displacement around vertical finger 36, forming vertical axis of rotation, at that pin 36 is contained on beam 12 and secured to it bracket 20. Respectively hinge finger ZZS turns approximately 90 degrees from the first position, parallel beam of 12, depicted on Φig. 1, in position, prescribed on Figure 4, where finger ZZS is at right angles to beam 12.

Respectively swivel connection and lower frame 33 form vertical rotation axis of, formed by pin 36 for wheel rotation 31 in direction of transportation and for move wheel 32 in position in front of. Also swivel connection forms horizontal axis of rotation, formed by pin ZZS for lower frame for downward movement for lowering wheels 31, 32 to ground.

Due to this, during operation of connection running wheels 31 and 32 transfers wheels from main beams 12 and provides movement relative to the beam for movement of wheels in downwards direction, remaining in tό same time parallel to direction of forward. Then beam 33V turns relative to the beam 12 and, respectively, turns the both wheels 31 and 32 in the transportation direction, transfer them at the same time wheel 32 under header, containing cutting system, in transportation position, as described above.

Same time, as description in the given document is presented in with respect to beams 12 reaper, usually during turning of shipping of the wheel are plotted relative to fixed on ground, front part of adhesion device stands fixed relative to tractor in time, as beam 12 and i < & T & shΐt & * zhttsh№ttt№ & L *® ΐ & * e? t · Gt; ~ -.

frame 12A reaper, supported beam, turn on its place above production wheels. This preferably, since header strongly not is shifted relative to tractor, so that vehicle can be is engaged in minimum space. This promotes smooth operation with minimum friction of tyres.

Channel 33F, welded on the upper part of beam 33V on end near with wheel 32, provides element of engagement for stop in cutting bar 6, which is placed under the cutting bar 6 and provides point of rest for reaper for receiving a certain load, both in vertical, and in transit directions. It may be exclusively point of rest or is made more cleverly, for example, in the form of locking devices for connection with cutting bar.

As shown on Figure 5, beam 33V has only length, to arranged wheel 32 as times before cutting bar b and under cover 13. Height of cutting bar provides, to wheel not obstructed reduced-either a compound element, when it turns and carries header. Beam has length, to wheel 32 not bottom before header. It is-practical restrictions of its length, which in otherwise just obstacle field of wheel 17. Also preferably a transport beam 33V in position at vehicle, which is behind the center of gravity of gun, so that some mass passed to hitch of the tractor.

Movement of lower frame 33 around vertical finger 36 is cylinder 37, installed between rotating support 35 and beam 12 on the joint 38. Movement of rotating support 35 is transmitted link 19 coupling apparatus cylinder 21, which continues between lever 19 adhesion device and rotating support 35. It acts in the form of connection of lever adhesion device and running wheel 32 same time, as header and beam 12 move relative to data elements.

Respectively, in transit position, transportation running wheel 32 is in position with front side of line in transverse direction, containing center of gravity of the machine, and the other from transportation running wheels is in the position with rear side line in transverse direction, containing center of gravity of the machine. Actuating device, ensures by cylinder 37 and link 21 of cylinder, moves lever adhesion device and shipping running wheel between field position and transportation position in simultaneous operation so, that machine remained neutralized with on transportation running wheels 31, 32 and on lever 19 coupling apparatus with lever coupling apparatus remains attached to tractor at movement to mentioned transportation position.

Rotating support 35 forms substantially universal connection, itself moves in horizontal flat sti around vertical hinge pin 36, which holds cylinders 37 and 21 in one and the same flat sti, general flat sti with lever 19 adhesion device in time, as shipping running wheels are mounted on the rotating support 35 for movement of deployment downwards, the initiated cylinder 33D.

Referring further to Figure 6, shown outline image versions circuit for controlling operation of a hydraulics reaper from tractor T. Tractor has first and second circuit 40, 41 supply of hydraulic fluid medium, each of which contains control valve 4 0V, 4 iv, made with the possibility of supply pressure of fluid medium in any of pairs of holes 4- ΟΑ , 40V source of 40 supply and 41a, 41V source of 41 supply, at that fluid medium returns in the other from holes under control of the valve.

In this embodiment, cylinder 21 steering mechanism, which represents a double-action cylinder, is regulated during steer control power supply source.

In this embodiment, lifting cylinders 17 and, 18Α are in the same circuit from source 41 supply, as shipping actuating cylinders 37 and 33D.

Is provided switching valve 43, which contains plunger 44, brought in action mechanical compound 45, described further and indicated on figs. 7-10. Valve 43 contains inlet holes 4 behind and 4 3V and acts with selection of outlet hole 43S and 43D or holes 43Ε and 43F depending on position of plunger 4 4.

In free position of plunger, valve the flow in holes 43S , 43D, to engage lifting cylinders 17α, 18Α , which are connected in series with configuration vedushchiivedomyi.

Are deploying cylinders 33D and 37 in series are actuated by two separate enough in certain sequence valves 46Α , 46V. One which actuates in certain sequence valve provides, to cylinder 33D fully advanced before provision of possibility cylinder 37 pulled, for room reaper in transport configuration. Other responsive in certain sequence valve provides, to cylinder 37 completely advanced before provision of possibility cylinder 33D pulled, for room reaper in field configuration.

Respectively in the given configuration, lifting cylinders 17α, 18Α and transportation hydraulics 37, 33D are in one and the same circuit, and cylinder 21 steering mechanism is in a separate circuit. This configuration is effective in configuration, where tractor has only two snabzhayushchikh circuit 40 and 41. In the situation, where available third circuit (not shown), it can be used for cylinder 14α for inclination of reaper.

Mechanical connection 45 has pair of guides of arrows 47, 48, which provide the driver visual indication of, when compound is in required place, to cause pressing of plunger 44. One of the hands 48 is connected to the element, carrying switch 43, and the other 47 is connected with mechanical compound 45, so that the arrows are aligned only in preset angular position of lever 19 coupling apparatus relative to the beam 12 and are held being aligned during displacement of components, as described further.

Angular position of arm 49 around axis of finger 20Α is adjusted by link 52, secured to arm 53, supported on vertlyuzhnom connection provided with slot link 42 with slot 42Α is connected with actuating mechanism 44 of valve 43 bolt 44Α , which may rotate. Provided with slot link 42 also is connected with pin 51, which has a hinge bolt 51Α , which is connected with slot provided with slot link 42 for free sliding and turning inside the slots. When hinged bolt 51Α of finger 51 strikes end of slots 42Α in provided with slot link 42, every further movement of will to force mechanism press on the actuating mechanism 44 of the valve, pressing on plunger with spring return of, which is part of valve 43, and to valve 43 with function of lifting on function of transportation. In any other place in slots of actuating mechanism of the valve, valve remains in mode of lifting. Device uses two overlapping provided with slots links for preventing jamming sliding and hinge compounds of finger 51Α. Link 42 has additional flange 42F for installation of indicator arrows 47. Pointer 48 is contained on the arm 49 so, to move with switch 43.

Mechanical connection 45 respectively includes arm 49, which carries switch 43 and is set in motion with rotary support 35 around finger 20Α ; finger 51, which carries pin 51Α and is installed on the end of the adhesion device 19 for movement with coupling device, and the link 42, contains on pin 44Α , which carries slit 42Α and presses on plunger by means of pin 4 4α, when finger 51Α reaches lower part of slots. So, data components act, providing possibility of operation of transporting system, activating switch 43, only when switch is located with required angle to beam 12 and act, preserving switch activated, same time, as coupling device and transportation system move relative to the beam 12 in intermediate position before transportation position.

Plunger 44 is put in action pin 44Α , which is pushed by the forward, pressing on plunger, when finger 44Α reaches end of slots 42Α. Place of switch 43 on the arm 49, which controls link 52, is located relative to link 42 with pusher so, that plunger is squeezed out, only when lever coupling apparatus is under specified angle relative to the beam 12 or close to it.

Geometry link 52 relative to shoulder 49 is made with possibility of movement of switch 43 so, that its plunger remained otzhatym the, as swivel connection 35 and lever 19 adhesion simultaneously move under action of cylinder 37 during displacement in transportation position.

Position actuate is selected so, to machine remained stable during transportation deployment. Position actuation action is intermediate position movement of adhesion device, and not in one finite point. I.e. system does not operates, as ordered system, where position is on one end of the movement of first sectional member machine, so that the following action can take place only after addition, as first composite element finished their movement. Connection, control switch 43, directly is put in action coupling device machine in contrast to other components, for example lifting running wheels or as part of actuation of the vehicle. I.e. position adhesion device, which actuates switch 43, allows the movement of for actuation of the vehicle, and the is not part of the actuation of the vehicle.

Criteria for selection of range of angles, in which vehicle is an active, include:

Avoiding extreme range in one side of the machine, which had least instability.

Keeping active lifting of in two extreme values of movement of front rotating cylinder, since this normal field working position for coupling device.

Keeping active lifted in position directly in front of in case of, if who-that wants to here mow for repeated mowing, cleaning field and T. d.

It should be small, so that lifting of was available operator in most positions adhesion device for facilitating field of operation.

So that in preferable embodiment, rear transportation cylinder can terminate their movement and moving shipping wheels, that they in correct position under machine before or when coupling fixture reaches transportation position, i.e. it strikes a stop.

So that in preferable version of operator can finish movement of adhesion device from intermediate position into locked position with front cylinder in such way, that valve can of switching from function transportation on function of lifting and provide system possibility of pucker wheels, lower header on the stop, close retainer, and then in reverse order data stage for release vehicle.

Is the following steps for room reaper in mode transportation of:

1. Preferably is moved tractor in position with equalizing adhesion device in parallel with tractor.

2. Are cylinder 21 steering mechanism, using controlled valve source of 40 power supply for turning reaper so, to upper pointer 47 not pointed to bracket 48 lower clockwise. In given position, plunger 44 of valve 43 returns under action of spring and not pulled away, providing possibility of lifting cylinders 17α, 18Α be in readiness state.

3. Completely, lifting cylinders, using source 41 from tractor so, to divert header from ground by means of lowering of wheels 17, 18 in lower position.

4. Are cylinder 21 steering mechanism, using source of 40 power supply for turning reaper of, until the pointer 47, 48 will not stand with required preset angle of lever coupling apparatus relative to the beam 12. In given position plunger 44 fully or partially pulled away, providing possibility of transportation circuit, containing cylinders 37 and 33D, be in readiness state and disconnect lifting cylinders. In preset position, beam 12 reaper is approximately 16 degrees from perpendicular with lever 19 coupling apparatus. This can be regulated.

Switching between functions usually is, when plunger partially pulled away, forming respectively range of angles instead of one specific angle, where vehicle is an active.

5. Are source 41 of power supply for complete motion of transportation razvertyvayushchego cylinder 33D and complete retraction transportation rotating cylinder 37. As stated earlier shipping are deploying and turning cylinders are connected in parallel with operating in certain sequence valve 46, mounted, for example, on 2000 pounds per square inch in pipeline to povorachivayushchemu cylinder 37. Transportation scanning cylinder 33D respectively fully extends and reaches pressure 2000 pounds per square inch, opening which actuates in certain sequence valve, providing possibility of passage of oil in turning cylinder 37 and completely pulls its, causing simultaneous movement of lower frame 33 vehicle and of lever 19 coupling apparatus. Mechanical connection above, formed by arm 49, carrying switch 43, link 52 and pin 51, carrying link 42, provides, to plunger 44 remained otzhatym during this displacement. Is contained installation pressure, at surpasses Aras which function switches. Necessary, that it is sufficiently high for complete successive lifting of machine, but below working pressure of tractor, so that can be engage turning cylinder. However, may be arranged machine, operating at low installation by means of increasing diameter cylinder or of change of geometry.

6. Movement of, induced by cylinder 37, are carried out so, to coupling fixture but not reaching its position, depicted on Figure 8, in the end of frame, where fixing element 19L on lever 19 adhesion device is positioned with the possibility of engagement fixing member 12L on beam 12. This stop adhesion device not reaching position provides possibility of reclosing of lifting cylinders by displacement of adhesion device cylinder 21 steering mechanism, and also avoids necessary provide, to coupling device and transportirovrchnye wheels were. their dedicated positions precisely in one and the same time. Then front cylinder 21 steering mechanism is used for completion of movement in the transportation position. During this movement of connection switches the hydraulic valve so, to result in action lifting cylinders. Then operator uses lifting cylinders for lowering reaper of on support 33F, which in the same time lifts the field wheels for maximum distance to ground surface and in this same time closes the hydraulic lock.

Respectively for vehicle, if lever coupling apparatus is not in correct position for transportation, when it was moved by displacement of chyaά·ShY№ swivel-joint 35, called cylinder 37, cylinder 21 is put in action for movement of lever coupling apparatus in required position.

With wheels in transit position, header can be is lowered relative to the beam 12 by action of cylinders 17α, 18Α for addition, to omit cutting beam on beam 33V , extending across under cutting bar for provide stability and for reduction of cantilever type loads.

For improving of connection between data elements can be provided connecting bracket 33F.

7. In given position (Figure 14), activated power source for retraction of cylinder 21 steering mechanism of, until reaper not His retainer 12L on beam 12. In given position changes specified angle of interaction between switch 43 and mechanical compound for release of plunger 44 so, to lifting cylinders 17α, 18Α again were cited in action and were in working condition.

8. Lifting cylinders drawn for landing cutting bar reaper on bracket 33F of transporting post and for lifting wheels 17, 18 in their most high position for overcoming obstacles.

Inverse operation from transportation in field mode is carried out as follows:

1. Preferably is leveled lever coupling apparatus in parallel tractor.

2. Disengage retainers 19L, 12L frame. This can be with retainer manually, or in cabin can be achieved release with electric drive. However more preferably this is carried out using cylinder 12 m lock, depicted on Figure 15 and depicted on Figure 6 in one and the same circuit, that and lifting cylinders 17α, 18Α.

3. Completely, lifting cylinders 17α, 18Α.

4. Are cylinder 21 steering mechanism of, until the pointer 47, 48 will not be are aligned, indicating, that mechanical connection otzhalo plunger, as switch 43.

5. Completely is transportation turning cylinder 37 and completely drawn transportation scanning cylinder 33D in sequence, which due above.

For a machine with central journal angle, with which coupling fixture should move relative to central line machine for achieving transportation position, is about 90 degrees in time, as normal working range front rotating cylinder is of the order of 45 degrees from central line.

In alternative configuration, movement of adhesion of fixture to rear frame may be accomplished by means of expansion of range front of cylinder and presence of instead of swivel-joint, as in acknowledged machine, of its connection with rear frame. Problem consists in the fact, that the cylinder may not have possibility of complete displacement in field mode with field wheels, bearing machine, or machine will be unstable. During operation of for addition, to machine remained stable operator will should deploy shipping wheel in transportation position or stabilize the intermediate position before complete displacement of cylinder. Control mechanism or control by means of distance sensors, as described previously, can be used for preventing actuation of the rotating cylinder on unstable coupler fixture in position of machine in field mode and/or function of hydraulic switching between operation steering control and transportation of. For operator can be provided removable limiting stroke stop, such as rod clutch, or the stop between coupling device and frame for reducing cylinder steering mechanism, therefore for convenient operation during field mode of stroke decreases to of the order of 45 degrees.

With connecting system, provided cylinder 37 and the rotating support 35, connected as with coupling device 19, and with beam 12, can be organize so, to some part or all displacement between coupling device 19 and beam 12 was is provided by means of actuation of the rear of cylinder 37, because as coupling fixture, and transport turn relative to the beam 12 and frame 12Α reaper. So, the front cylinder 21 is not required any additional range. When transportation back cylinder 37 turns in field mode, front cylinder 21 operates, as usually on machine with central journal, which contains no transporting system.

Necessary notice, that with the use of preferred versions, mechanical lock between coupling device 19 and beam is also important part of the position control. It allows the operator completely put in operation back cylinder 37, and then finishing use of front cylinder 21 to impact stop.

Alternative mechanical stopper would be provision of indicator or control of so, to operator started front rotating cylinder 21 in correct position before engagement vehicle.

In preferable embodiment of coupling fixture actually is adapted to be hitched to rear frame at stopping of. This not only not allows the operator unwittingly engage turning cylinder 21 and 37 during displacement of in transit position, but also provides the reserve connection, so that if any-either of cylinders 21 and 37 mechanically refuses, retainer all is will ad.

In preferable embodiment, above described, system activates cylinder 12Μ lock with lift, so that when operator lowers header on frame vehicle and in the same time lifts the field wheels, retainer 12L is activated. Usefully-stimulation of operator lifting ripper with support before turning vehicle.

In alternative configuration, since two quite complex control mechanism, described above, are not strictly required for for controlling configuration, can be provided simplified set of pitches. Simply system should be 1) turned shipping wheel under frame with use of cylinder 33D and 2) turned machine in transportation position with application of rear of cylinder 37.

For a machine with central journal, preferably, to back cylinder was completing an its turn so, to added the third stage completion of movement with front turning cylinder 21. This require, to operator started in the range, which allows carry switching of rear cylinder. It is made considerably lighter-than-by adding visible mechanical stop lock 12L in transit position.

Alternative would be provision of indicator, to operator can firstly arranged coupling fixture 19 in correct position. Then rear turning cylinder 37 may carry its switching of in correct transit position.

One more reason complex control consists in the fact, with acting coupling device, at rotating all time in the same direction, that and transportation wheel in the end of the "Selections", when shipping wheel firstly dug machine from ground, machine becomes unstable. It therefore, that COG is in front of the triangle, formed by the wheels and coupling device. This prevented limitation range of angles adhesion device, which involves transport. One more solution can be addition of ballast for movement of center of gravity backwards, or on other types of machines this problem may be absent completely.

In preferable embodiment of cylinder lock is connected in parallel lifting cylinder, therefore it automatically opens, at movement of lifting cylinders for lifting the riper with support 33F. This feature also prevents turn the vehicle without lifting riper with support, that can cause problem, since support may please in machine.

Referring further to Figure 7, 11 and 12 screen 5 shown more are and has upper panel, formed by central section 5α, and two side sections 5-b, 5Ε , all aligned across frame and forming common rear edge, located at a distance of from beam 12. Sections are separate, each of the inner side edges of the two side sections has a blocked joint strap 5D, lying over edge part of central section. Central section overlaps lateral sides for tensioning the whole screen, when is in field mode, decreasing respectively vibration screen.

Outside side sections is pair of hanging side panels 5c and 5F, which prevent deviation in side.

Side sections and side panels attached to the frame and to each other, to remain in fixed position during operation of. Central section 5a is connected with post ZZA support frame 33 lever 5L, which is fixed bracket 5Ρ to the upper surface of central section 5α, and bracket 5Q to facing forward surface of post ZZA. Link 5L has rigid post 5R, connected with brackets universal compounds 5Τ and 5S.

Provision of screening of guard is according to standard safety iso for machines, equipped with plyushchilkoibichevogo type, due to more high-outlet hole, than in roll plyushchilki. When header is installed in mode of transportation, transportation frame 33 lowers down and rotates grid approximately 90 degrees.

Shielding panel respectively consists of three parts, the central part is attached to of transporting frame, following behind it the, as it passes through movement of lowering of downwards and turning. For addition, to screen is attached to transport facility the, it turns, as described above, is used double cardan hinge link.

Further referring to Figure 16, shown alternative version of realisation control operation of hydraulic systems from sources of 40 and 41 supply of tractor in the form of replacement of for circuit of Figure 6. Multiple composite elements are common,. and consequently are used similar linked designations, so that their description in the given case repeat itself will not be.

In this version of switch 43 is connected to cylinder 21 steering mechanism in one circuit and with production cylinders 37 and 33D in other circuit. In this version, there is no mechanical connection, which controls plunger 44, but instead it is brought in action with a switch 60 on panel 59 control, set in action manually in cabin of tractor for feeding energy from source p supply tractor on switch 43. Switch 60 represents two-position switch, acting between two modes of steering control 61 coupling device and transportation of 62. For addition, to prevent selection of operator of tractor modes in incorrect time, is pair of warning light signals 63 and 64 and relay 66, which is in response to sensors 65Α , 65V distance, which is determined angular lever position 19 coupling apparatus. Respectively on lever 19 coupling apparatus can comprise plate, which sblizhaetsya with sensor 65Α and shows, when the lever coupling apparatus is under preset angle, indicated above, by inclusion of lamp 63, and shows, when the lever adhesion device is located close to the preset angle, definite above, by inclusion of lamp 64. In this version of configuration is such, that cylinder steering mechanism and transport hydraulics are in one and the same circuit 41, and lifting cylinders are in separate circuit respectively is contained two sensors of 65Α , 65V , distance, one for each indicator lamp. One sensor and lamp communicates operator, that angle reaper relative to adhesion device is within range for beginning of transportation deployment. The other transmitter and lamp determines the permissible rotary range of reaper, when it passes in mode of transportation. It prevents operator, that function transportation is accessible, and holds hydraulic switch involved in oil delivery into shipping cylinders for transporting sequence of.

For room reaper in mode transportation of necessary to the following:

1. Completely to nominate lifting cylinders with use of source of 40 supply so, to sever header from ground by displacement of wheels in their lower position.

2. To switch 60 on "steering gear" 61.

As a rule, switch will in given position during regular use reaper in microwave.

3. Harness source 41 of power supply for displacement of cylinder steering mechanism for turning reaper of, until in-first not is started green light "to begin transportation of" 63, representing the, that position reaper relative to lever coupling apparatus is required position, to proceed for transportation. In given position, also should engage yellow light "transportation is accessible" 64, indicating that position reaper relative to lever coupling apparatus is in the range of turning, in which allowed to perform transportation.

4. To switch 60 on "transportation" 62 for addition, to source 41 supply led in action transport system by means of valve 43 so, to completely to nominate transportation scanning cylinder 33D and completely pull transportation turning cylinder 37. So, wheels are moved into transportation position, and lever coupling apparatus is moved into position near, but with separation gap from the lock 12 l.

5. To switch 60 on "steering gear" 61 for addition, to valve 43 returned under action of spring, being cause actuate cylinder 21 steering mechanism so, to steering gear coupling device is in working condition.

6. Pucker cylinder steering mechanism of, until fixing element 19L reaper not His retainer 12L on bearing frame.

7 pucker lifting cylinders 17α, 18Α , using feeding for installation of cutting bar reaper on bracket 33F of transporting post.

For room reaper in field mode is necessary to perform the following:

1. Removed from engagement retainer bearing frame with coupling device.

2. Completely to nominate lifting cylinders.

3. To switch 60 on "transportation" 62 for addition, to-engage valve 43 from cylinder steering mechanism for actuation of valve in transporting sequence of.

4. Completely to nominate transportation turning cylinder and completely pull transportation scanning cylinder.

5. To link switch on "steering gear".
