Design scheme and operating principle of a centrifugal seed distributor of a pneumatic grain seeder

Abstract

The disadvantages of existing distribution systems of pneumatic grain seeders are presented. A design scheme of a centrifugal seed distributor is proposed and the principle of its operation, the causes of uneven distribution, and the history of the development of grain seeders, in which the principle of central seed dosing is implemented, are described. The analysis of designs of pneumatic grain seeders is carried out, the types of their dosing and distribution systems are revealed.
