Abstract
Изобретение относитс к сельскохоз йственному машиностроению, в частности к пневматическим высевающим аппаратам, Цель изобретени - повышение качества точного высева и снижение энергоемкости. Аппарат содержит семенную камеру 1, вертикальный высевающий диск 2 с коническими присасывающими чейками 3, вакуумную камеру 4. Ячейки 3 выполнены с эластичным покрытием из материала, коэффициент трени сем н о поверхность которого больше 0,7. Угол конусности каждой чейки больше двойного угла трени сем н о поверхность покрыти . 3 ил.The invention relates to agricultural machinery, in particular to pneumatic sowing devices. The purpose of the invention is to improve the quality of precision sowing and reduce energy consumption. The apparatus comprises a seed chamber 1, a vertical seed disc 2 with conical suction cells 3, a vacuum chamber 4. Cells 3 are made with an elastic coating of material, the coefficient of friction of seeds on the surface of which is greater than 0.7. The angle of taper of each cell is greater than the double angle of friction of the seeds on the surface of the coating. 3 ill.
