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

FIELD: agriculture.

SUBSTANCE: planting attachment contains body with seed and evacuated vessels, seed disk and lamellar release. Seed disk allows two rows of dosing elements located on different diametres. Dosing elements of external row are connected to neighbouring dosing elements of inner row by channel. Channel width is less the diametre of dosing element. Connecting port is located on-the-mitre to radial plane, passing through the centre of top dosing element in direction, opposite to sense of rotation of seed disk. Values of porting angle is in the range from value more than angle of friction of seeds about material of surface of seed disk up to value less than - π/₂. Operation plane of kicker of "excess" seeds is located perpendicularly to direction of porting, connecting dosing elements of external and internal rows. Bottom edge of kicker of "excess" seeds partially overlaps dosing element of inner row. Application of invention will improve quality of one-piece feeding of seeds by dosing elements of planting attachment.

EFFECT: improvement of quality of one-piece feeding of seeds by dosing elements of planting attachment.
