A large turnover plow, comprising a plow frame (1), a traction frame (2), a rotating shaft (3), a hydraulic cylinder (4), plow poles, plow walls (7), plowshares (8), a connecting plate (9), balancing plates (14), a walking wheel and a walking wheel support frame. The traction frame (2) is fixedly installed on the plow frame (1), and the rotating shaft (3) is installed on the plow frame (1) below the traction frame (2) one end of the hydraulic cylinder (4) is fixed on the plow frame (1), and the other end is fixed on the traction frame (2) the plow poles are divided into an upper plow pole (5) and a lower plow pole (6), and the upper plow pole (5) and the lower plow pole (6) are symmetrically and fixedly installed on the plow frame (1) at equal intervals from one end close to the traction frame (2) the plow walls (7) are fixedly installed on the plow poles the plowshares (8) are fixedly installed on the plow walls (7), and the plowshares (8) comprise a first plowshare tip (81) and a second plowshare tip (82) the balancing plates (14) are arranged between the plowshares (8) and the plow poles the heights of the upper plow pole (5) and the lower plow pole (6) are subject to arithmetic sequence decreases from one side close to the traction frame (2), and the heights of the upper plow pole (5) and the lower plow pole (6) refer to the distance between each plow head plane and the central plane of the plow frame, wherein the plow head plane is a plane formed by the three points of the first plowshare tip (81), the second plowshare tip (82) and one point on one end of the balancing plate (14), the one end of the balancing plate (14) being the end not connected to the plow wall (7) the walking wheel is installed on the walking wheel support frame, and the walking wheel support frame is fixedly installed in the middle position of the plow frame. The plowing depth of the large turnover plow is consistent and adjustable, and the plowed land is level.Linvention concerne une char
