Arrangement of two guide plates

... 2.1 With conveyor bottoms (10, 12) which oscillate in opposite directions and which can experience a lateral inclination, there are guide plates (14, 16) which are intended to prevent the material on the conveyor bottom (10, 12) from slipping towards the downhill side. However, a weak point proves to be the transition between the two conveyor bottoms (10, 12) when the guide plates (14, 16) move away from one another and the conveyed material accumulates in a gap formed between these. The flow of material is thereby disrupted and the guide plates (14, 16) are damaged when they move up to one another again and the gap formed between them is blocked. 2.2 To solve this problem, the guide plates (14) located upstream are so designed that they overlap the downstream guide plates (16) in a roof-shaped manner at least over part of their length. 2.3 Such an arrangement of guide plates (14, 16) is found especially in combine harvesters. ...

AGRICULTURAL HARVESTER WITH CLOSED LOOP HEADER CONTROL

A method and apparatus for controlling an agricultural harvester (200) having a cut crop receiving header (202) coupled to a hydraulic (206). The header (202) applies a force against the ground that is adjusted by applying pressure to the cylinder (206). Proportional raise and lower valves (118, 120) control the pressure in the cylinder. A pressure signal representing cylinder pressure is received. The difference between the measured pressure and the setpoint is used to compute input signals, which are transmitted to the valves (118, 120). Cylinder pressure is maintained substantially at a setpoint, the setpoint being adjustable in response to varying terrain (220). The setpoint is set to a first value in falling terrain and a second value in rising terrain. At the top of a hill, the setpoint is reduced below the first value until ground contact is regained, and the pressure is recharged above the second value.

Harvesting machine feed mechanism

HARVESTING MACHINE FEED MECHANISM Abstract of the Disclosure A self-propelled combine has a mobile body with a forward inlet, a forward transversely elongated harvesting header, and a feeder housing extending between the header and the inlet for feeding crop material from the header to a crop treating mech-anism in the combine body. The feeder housing has an upwardly and rearwardly inclined floor with a chain and slat type conveyor mounted in the housing and having a lower run moving upwardly and rearwardly above the floor. A flat pan-like crop deflecting member is mounted on top of the floor underneath the conveyor and includes a plurality of generally fore and aft vanes that extend a substantial portion of the length of the floor. The crop de-flecting member is swingably mounted on a pivot extending through the floor, and a hydraulic cylinder is connected to the pivot on the underside of the floor to swing the deflector member between alternate positions wherein the vanes direct crop material moving along the floor toward one side of the body inlet or the other, whereby, when the combine is operating on a hillside, the crop material can be directed to the uphill side of the crop treating mechanism to reduce the buildup of material on the downhill side while the crop is being treated.

Agricultural harvester with closed loop ground tracking control

A method and apparatus for controlling an agricultural harvester having a cut crop receiving header coupled to a hydraulic cylinder. The header applies a force against the ground that is adjusted by applying pressure to the cylinder. Proportional raise and lower valves control the pressure in the cylinder. A pressure signal representing cylinder pressure is received. The difference between the measured pressure and the setpoint is used to compute input signals, which are transmitted to the valves. Cylinder pressure is maintained substantially at a setpoint, the setpoint being adjustable in response to varying terrain. The setpoint is set to a first value in falling terrain and a second value in rising terrain. At the top of a hill, the setpoint is reduced below the first value until ground contact is regained, and the pressure is recharged above the second value. Alternatively, header height may be measured and the valves controlled to maintain header position substantially constant relative to the ground or the harvester frame. Header lateral tilt is controlled while controlling either cylinder pressure or header height. A resume function returns the header from a raised position to a cutting position at the beginning of a new row.
