FIELD: agriculture.
SUBSTANCE: invention relates to the agricultural machinery industry and can be used in the construction of a grain combine harvester. The cleaner of the grain combine harvester comprises a transition grate, sieves, grain and tailings screw conveyor, return elevator with finishing threshing device, a distributor and a ventilator. The distributor is made in the form of a screw and has a housing. To reduce the load imbalance and to improve the quality of work of cleaning along the lower part of the housing of the distributor an additional beam is mounted, which is attached to removable flaps on the edges of the beam in direct harvesting, and at pickup of rolls - in its central part.
EFFECT: device enables to load more uniformly the system of cleaning of the grain combine harvester in width, to reduce grain losses behind the thresher and to reduce the entering of loose grain grains to the tailings screw conveyor.
