Pneumatic single-grain seeder

摘要

The pneumatic agricultural seeder has a separating housing that is provided with a separating region (10), in which a constantly maintained excess pressure is generated over a refill line such that the differential pressure is produced over the refill line in continuous manner. The differential pressure lies at perforations on a separating drum (3). A partition wall (32) is arranged for a wall of a seed reservoir (4) in a lower region of a seed shaft (26) at an upwardly opening angle (33) of less than 20 degree.
