Suction type seeder with mechanical seed delivery - has rotating paddle wheel to carry seed from vacuum release zone to ground discharge zone (PT 20.9.79)
Реферат: The seeder has a vertical rotating disc(1) with a circle of holes(4) at its periphery. The disc is subjected to a vacuum on one side so as to hold a single seed in each hole. The holes are smaller than the seed. The seed is carried by the disc to a release zone(7) where the vacuum is not applied. A paddle wheel(8) is rotated, taking its drive from the disc drive. The wheel rotates in a casing (9) which, together with the blades of the wheel forms cells for transport of the seed from zone(7) to a zone(11) where it is discharged to the ground.
