PNEUMATIC PLANTING UNIT Russian patent published in 2009 - IPC A01C7/04 

FIELD: agriculture.

SUBSTANCE: planting unit includes vacuum chamber, seed disk with measuring components, kicker of excess seeds. Kicker-box of excess seeds allows vacuum chamber, connected to vacuum chamber of planting unit. In working surface of kicker-box, located from the side of from the side of row of measuring components of seed disk, there are implemented sticking holes. Dimension of sticking holes of kicker-box is less than dimension of measuring components of seed disk. Operation plane of kicker-box is located on-the-mitre, to tangent line of circumference of centers location of measuring components, traced in cross point of working surface of kicker-box with disposition circumference centers measuring components. Value of disposition angle of operation plane of kicker-box less the value of angle of friction of seeds of sow crops by surface of seed disk.

EFFECT: conditioning of single-piece feeding of seeds by measuring components of planting unit.
