ROTARY PLOUGH WITH VARIABLE WIDTH Russian patent published in 2014 - IPC A01B3/30 

FIELD: agriculture.

SUBSTANCE: invention relates to the agricultural machinery industry, in particular to rotary ploughs for a smooth plowing. The rotary plough with a variable width comprises a support frame (1) with a central longitudinal beam (2). The frame (1) is pivotally connected to the movable spragger (3) with the ability of its deflection at an angle α within 0-45° in both sides relative to the axis (4) of the movable spragger (3). On the spragger (3) the plough housings (5) are mounted with the ability of rotation on the axis (6) at an angle β in the range of 0-30° in both sides counterclockwise or clockwise. The front part of the spragger (3) a slider (7) is fixed. The arcuate guide (9) is fastened to the lower part of the supporting frame (1) and comprises openings (10) on both ends for mounting the slider (15) stop. The plough housings (5) with the hydraulic cylinders (17 and 18) through the rods (12) are mounted with the ability of coordinated rotation on the axes (6) with the levers (13) rigidly connected to them and the fingers (14) pivotally connected to the rod (12). Turning of the plough housings (5) is limited by rod stop (16). The plough housings (5) comprise the moldboards mounted on the rotary rack at an angle to each other with wings of left (20) and right (21) soil overturning, of left (22) and right (23) plowshare.

EFFECT: solution enables to simplify the design and improve the operational reliability of the rotary plough.
