According to the invention, the body 50 has a container 1 for the grains 7, would be solved in that the openings are larger than its refill opening, the grains to be received by means of a sealing cover and are closed by the surrounding 11. The container 1 is divided by a catch of the Säorgan in the radial direction, dividing wall 12, both sides of which, as is already known, and that in the Kprnauf pipe system 13 and 13, the openings 13 _X and 13 ₂ with a radial receiving area Space between the 55 compressed air is applied. The bottom 12 'of the wall of the container and the periphery of the container 1 separates the zone for releasing the grain-moving mammalian organ, which is an air zone from the pressure zone. The container 1 is guaranteed on the other passage. The air flow that passes this clearance by means of a circulating saw organ 14 drives the grains against the closed, which distributor will be discussed in more detail below, so that it is carried along much more easily and is carried along with the shaft 3 via suitable means 3 '. The airflow through the peripheral play- is driven. At the circumference of the Säorgans the space presses the grains against the periphery of the wall of the container 1 as a conical wall 16 from Säorgans, so that they are gradually formed by this. -

Outside of the areas, which are somewhat larger than the grain drive zone to be sown, the grain kernels are arranged at equal distances from one another with the disk 14, but without compressed air injection, on the circumference of the disk 14, whereby and are therefore not driven, naphdemas which are brought about a long radial clearances, which is smaller than the grain kernels in the slots with a certain kernel, between the peripheral surface of the disk w speed, they remain in the loading 14 and the solid wall 16 The position to be removed through the openings 17 is to have a certain number of slits, the condition of the surface and the top 18, which are attached concentric to the shaft 3, surface formation of the periphery of the washer at 4 and c | er.

The above-described seed drill works as it does outside on the container 1 and on which follows: If a suitable pressure acts on the tubular bell-shaped disc 24, which line system 13 and the openings 13 and 13 ₂ , as is provided with holes 25. The container 1 then has a sliding of the grains 7 under a guide wall 26. In the vacuum chamber, the force of gravity into the container 1 is favored. 27, which is arranged peripherally to the disk 24. The disk 14 with its openings 17 is arranged around a round, fixed knife 28, which is offset. The openings must necessarily ensure the mounting of the grain 7, the ¹ in example adapted to the shape of the grains used are the openings 30 25th A game e is here too and may be slightly larger than this. The radial play e between the solid wall Γ and the surface must be provided for the proper functioning of the device 24 'of the disk 24. It can be seen that, if it is large enough, the size of the type of grain used is again limited by the disk to rotate around the shaft 3, so that the pulley 3 'is driven, the grains 7 of the grains do not slip through but also do not wedge 35 in sequence on the circumference at the point of the. The disc 14 holds the body play e are brought, in such a way that those which are located in the openings 17, and because only one grain 7 alone is in a hole 25 subjects it to the pressure effect of the flow through it until it comes out of the manifold, the air. This embodiment of the invention allows a 12 'limited periphery of the disc 14, the radial 40 considerable acceleration of the work and a loss of play e, which can be seen between the disc 14, the improvement of the distribution of the grains Wall 16 and the openings 17 are made according to the exemplary embodiment according to FIGS. 6th
