Pneumatic single grain seeder

摘要

The seeder has a separating drum with separating belts rotating against a drum surface within a region of perforation rows. The belts are formed like a roof in cross section and arranged on both side roof surfaces of the perforation holes. Deployed pipes (17, 18) are guided to a deposition device by the holes. Inlet areas (19) of the pipes are funnel shaped and/or y-shaped and arranged between the belts such that the areas collect seed grains isolated and released from the holes and delivered into respective and/or common deployed pipe.
