DISTRIBUTOR OF PNEUMATIC GRAIN SEEDER Russian patent published in 2011 - IPC A01C15/04 

FIELD: agriculture.

SUBSTANCE: distributor comprises a supply pipeline with a discharge, a sown material guide and a distributor head with discharging nozzles and a reflector. The sown material guide is made of a fine mesh and represents a chute. The chute surface consists of two sections: rectilinear and arched ones. The chute tightly adjoins the inner wall of the supply pipeline with its lower end, as well as the left and right sides. The upper end of the chute is directed into the reflector centre. At the same time the rectilinear section is arranged directly in the horizontal part of the supply pipeline at the angle of 10…20° to the horizontal line, and the arched one - directly in the discharge. The length of the rectilinear section and the radius of the arched section are determined depending on the diameter of the supply pipeline.

EFFECT: distributor has a simple design and will make it possible to increase evenness of sown material distribution along seed ducts of the seeding machine and to reduce labour intensity of this operation.
