APPARATUS FOR WIPING OF GRASS SEEDS Russian patent published in 2006 - IPC A01F11/04 

FIELD: agricultural engineering, in particular, equipment for wiping and cleaning seeds of perennial grass and other crops.

SUBSTANCE: material to be treated is charged into wiping device. Rotating drum grasps material by means of whips to provide wiping thereof by moving over wiping surface. Wiped seeds with impurities are fed through discharge window and material guide, and further via feeding device to aspiration channel. Light particles are entrained by air flow generated by means of fan blades and drawn into channels defined between fan blades, while cleaned seeds are discharged by gravity from aspiration channel into receiver. Large-sized impurities are discharged from fan blades into settling chamber. Small-sized particles are delivered through used air exit branch pipe.

EFFECT: increased efficiency in cleaning of wiped seeds from impurities.
