SINGLE-ROTOR COMBINE HARVESTER THRESHING-SEPARATING DEVICE FEED BEATER Russian patent published in 2025 - IPC A01F12/10 A01F7/00 

FIELD: agriculture; machine building.

SUBSTANCE: claimed invention relates to agricultural machine building, in particular to threshing-separating devices of combine harvesters. Feed beater 3 of threshing-separating device of single-rotor combine harvester contains housing of cylindrical shape, discs installed on ends of housing and rigidly fixed on it, turns located on external surface of housing, and shaft passing through discs. At that, feed beater 3 is hingedly installed in the frame on two bearings and rotates around the axis in the transverse direction relative to the combine, there are plates installed on the housing in its central part and rigidly welded to it, central ribs coupled with housing and plate and rigidly welded to them, and side ribs coupled with housing and lead-in part of turn and rigidly welded to them. Turns on the cylindrical surface of the housing are installed symmetrically relative to the length of the housing of feed beater 3 and are located at an acute angle α₁ to the axis of the housing of feed beater 3, wherein feed beater 3 is symmetric relative to transition section 4 and is located directly above upper lead-in part of rotor 5, while process mass is fed from feed beater 3 into lead-in part of rotor 5 from above. Working surface of the planks in the transverse direction of the housing of feed beater 3 is located at an angle α₂ to the axis of the cylindrical housing of feed beater 3 and is inclined to the side opposite to the direction of rotation of feed beater 3.

EFFECT: invention provides for an increase in the productivity of a grain harvester, as well as an increase in the resource and service life of the structure.
