FIELD: agriculture.
SUBSTANCE: invention relates to agricultural machinery industry. The threshing device for the grain combine harvester comprises a threshing drum with a concave and at least one drum located behind the threshing drum to bypass the threshed mass from the threshing area. In the peripheral area of the threshing drum the threshing planks are located at a distance from each other. In the peripheral area of at least one drum located behind it, the planks are also located. The peripheral speeds of the adjacent drums are synchronised with each other so that the planks of the adjacent drums in the area of rotation and removal of the harvested mass always occupy a position opposite to each other or with a slight deviation from it with advancing or lagging.
EFFECT: threshing device provides optimisation of the threshing process and transportation of the harvested mass.
