DEVICE FOR THRESHING GRAIN CROPS ON ROOT Russian patent published in 2018 - IPC A01D41/08 

FIELD: agriculture.

SUBSTANCE: device comprises passive stalk splitters 8, active working elements in the form of rollers 1 with stripping elements 2, as well as an air duct for suctioning threshed grain from the threshing zone and feeding it to a hopper. The rollers 1 are arranged in the horizontal plane in a row along the front of the threshing unit movement and are oriented with the rotation axis 5 in the movement direction. The rollers 1 are grouped in pairs with the formation of a threshing zone in the clearance between the rollers 1 in each pair. When stripping grain crops, the stripping elements 2 of each roller 1 in each pair move from bottom to top. The air duct has an increasing cross-section along the course of the grain-air mixture.

EFFECT: reducing grain losses due to under-threshing and premature shedding.
