FIELD: agriculture.
SUBSTANCE: group of inventions relates to agricultural engineering. The mechanism of repeated threshing for grain harvester comprises a drum, a housing and a reflector. The drum has threshing elements mounted on it, extending substantially radially. The drum is mounted with the ability of rotation in the housing, at least partially surrounding the drum. The housing has a wall part with corrugated bars and the inlet and outlet openings. The reflector has an inclined connecting plate and an arcuate deflecting plate. The inclined connecting plate with its one end is connected to the deflecting plate and the other end - with a hinge joint attached to the housing. The hinge joint enables to rotate the reflector for selective deflecting of the treated crop in the first path to the drum for repeated threshing or the second path to bypass the drum.
EFFECT: group of inventions provides minimal damage to grain crop.
