The workflow of the device according to the invention is as follows:

The seed is poured into the seed container 7 as a mass. The drive pulley is via the feed lever 20 3 and thus the distributor disk 5 in cycles

Offset. As a result, the seeds or the pellets roll into the depressions 5 of the through bores 13 and are conveyed to the distributor housing 9 in cycles. Before that, by a partition 8, the is permanently installed within the seed container 7, the remaining seeds or pellets from the distributor housing held back. By rotating the inclined distributor disc 4, the seeds are approximately Rotated 240 °, whereby the position of the same is changed in such a way that a complete segregation of the seed is achieved, as a result of which the individual seeds are deposited within the depressions 5 and is guaranteed.

With further rotation of the distributor disk 4, the seeds or pellets finally get into the distributor housing 9. As soon as the predetermined number of through holes, so the segment, within the

Distributor housing, the distributor disc 4 stops. Now the ejector pins 11 are on the Swing arm 15 is moved up through the through holes 13 and into the depressions 5, whereby the in The seeds located in the depressions 5 are mechanically ejected through the tips of the ejector pins 11 and fall into the collecting space 32. From the collecting area 32 The seeds get to the distribution lines
