sAE rollersarranged each having the desired mixing ratio corresponding rotational speeds can be driven. The metering device is extremely compact in the structure thereby, as mentioned in particular carry out the subsequent arrangement on existing soil working tools is appropriate. With regard to the simple adaptation to different seed or different Another advantage addition granulates, it brings that on the hollow shaft and also to the core shaft, the both have a catch profile, both cell wheels with different for different grain sizes or quantities of seed cell sizes, A granular fertilizer or plant protection products, as well as solid discs or. Dummy disks in alternating throughput quantities are attachable to reduce the selectable order. It must therefore only a constructional unit laterally removed and against a prepared other unit on the same geometrical axis with two other sAE rollers exchanged or the hollow shaft and the power and projecting core shaft with a new register from cell wheels and solid or dummy disks is to be retrofitted. As parameters for the dosage the adjustable rotational speeds are sAE rollers on the basis of the number and the configuration of the execution of the cell wheels and the number of the solid discs and the concrete, the throughput also be governed by the slow down and the driving speed.

A 3 and 4 relative to each lie sAE rollerscontainer discharge slot-like. This, whilst on a common geometrical axis arranged one behind the other, but a hollow shaft 5 and 6 are used as mechanical drive shafts and projecting beyond it a these penetrating core shaft, 7 and 8 are slipped on which cell wheels non-rotatably as required solid discs. The cell wheels comprise circumferentially outwardly open compartments 7 9, large enough, to receive a seed or a always constant number of seed grains). The diameter of the cell wheels are always of the same size 7, but the width can, the depth and the number of chambers at the periphery 9 vary. The cell wheels 7 are in some way driver, in each case a seed container discharge[...] from the when the extract. Depending on the filler material of the container is taken from each type [...] also instead of a granulate, therefore, for example, always constant amount fertilizer central granulates in.

[0010] Whereas Community throughput and thus also for the mixing ratio are, then, the 7 chamber sizes of the cell wheels, the number of the cell wheels 3 or 4 and also the rotational speed within a 7 sAE roller. It 10 and 11 together with a symbolically represented are two controllable electric motors 12 provided transmission. The motor 10 transmits torque to the hollow shaft 12 by the gear 5 be.
