SEED DRILL FOR OUTPUTTING SEED MATERIAL Russian patent published in 2009 - IPC A01C7/00 

FIELD: agriculture.

SUBSTANCE: seed drill for outputting seed material has at least one dosage system and at least one system for outputting seed material. Each system of outputting seed material is connected with the respective dosage system and has a runner of seed material and conveying wheel with peripheral area. The peripheral area of the wheel is equipped with several separate surfaces attached to each other, and placed close to at least one area of the runner. The conveying wheel is made in the form of bristle wheel. The separate surfaces of the wheel are made in the form of bristle sets passed along the peripheral area, mainly, in the radial direction. The conveying wheel is placed relative to the stream of seed material passing downward through the dosage system with the possibility of gripping seed material taken by the outputting system with the intended frequency and of speeding it. Moreover the conveying wheel and runner of seed material are made with the possibility of interacting with each other. The runner is fixed in the set place relative to the peripheral area of the conveying wheel with the possibility being joined with the conveying wheel. The runner is made in such a way that the several separate surfaces on the peripheral area can periodically decline due to rotation of the conveying wheel.

EFFECT: compactability of the seed drill, accurate and efficient outputting of seed material.
