Abstract
The article considers the issue of substantiating the distributing working body parameters for a pneumatic grain seeder. Work on the subject matter is mainly experimental in nature and not sufficiently deeply worked out theoretically. Based on computer simulation, the article determines the most preferred layout of the distributor dividing head, establishes a rational form of the reference cone and the location of the outlet pipes. Based on the simulation of the movement of seed grain particles, the individual design parameters of the distributor dividing head are specified. The results of experimental studies are presented confirming the theoretical background.
