Abstract
The present invention relates to a seeding machine of the pneumatic ejection type. The seeding machine includes an apertured distributor disk 2 which rotates past a suction chamber 3 terminating in an end wall 4, and an ejector venturi 1 is juxtaposed to the side of disk 2 opposite to chamber 3, neck 7 of said venturi being located in line with the end of said chamber and having an inlet port 8 which straddles the path of travel 5 of the suction apertures in disk 2. The machine has an application to the sowing of light seeds such as vegetable seeds.
Claims8
A seeding machine of the pneumatic ejecting type, especially intended for sowing light seeds such as vegetable seeds, said seeding machine including an apertured distributor disk (2) for carrying seeds, adapted to rotate in front of a suction chamber (3) located on one side of said disk (2) and interrupted in a releasing zone, and an ejection venturi (1) directed towards the ground and juxtaposed to the other side of said distributor disk (2), the convergent section of said venturi being connected to a source of compressed fluid, the neck (7) of said venturi having an inlet port (8) for the seeds carried and held by said distributor disk (2), said port (8) being located in said releasing zone, and the venturi neck (7) is so disposed with respect to said suction chamber (3) that, when said seeds are released from said distributor disk (2) they already lie substantially in the venturi neck (7).
