FIELD: agriculture.
SUBSTANCE: invention relates to agricultural machine-building. Threshing mechanism of grain combine includes at least one threshing drum with threshing-separating concave. On circular surface of threshing drum threshing bars are placed. In direction of circular surface and/or in axial direction of threshing drum, at least, one grip, projecting beyond threshing drum circumscribed circle, is located on it.
EFFECT: presence of grips favours acceleration of harvested mass guided to threshing mechanism to circular rate of grips, due to which consumption of harvested mass flow and degree of grain separation increase.
