THRESHING AND SEPARATING DEVICE OF THE COMBINE HARVESTER Russian patent published in 2023 - IPC A01D41/12 A01F12/28 

FIELD: agriculture.

SUBSTANCE: threshing and separating device of the combine harvester contains a frame, a threshing drum, a distributor beater pivotally mounted in the frame, a concave installed under the threshing drum, two threshing and separating rotors (5) pivotally mounted in the frame transversely to the longitudinal axis of the combine and rotating in opposite directions relative to each other, decks (6) installed under the threshing and separating rotors (5), and a grain board (7) installed under the working bodies. Shields (9) are pivotally mounted on the sidewalls located along the edges and in the central part of the deck frame (6), and on the ribs (10 and 11) located along the sidewalls and hinged on the central sidewalls of the deck frame (6). Shields (9) are fixed on the deck frame (6) with pins and on ribs (10 and 11) with bushings, washers, bolts and nuts. On the bracket (22) of the rotor casing (5), a drive (18) is fixed at one end, fixed at its other end on the rods (15) and structurally interconnected rods (16, 17 and 19) by means of cylindrical hinges. The rods (14) and the structurally interconnected rods (16, 17 and 19) are pivotally hinged, respectively, with the ribs (10 and 11).

EFFECT: increased productivity of the combine harvester, reduced load on the cleaning system during the rectilinear movement of the combine, reduced grain losses when the combine harvester operates on transverse slopes, as well as the ability to quickly adjust the combine harvester when harvesting various crops.
