Large turnover plow

Abstract

The invention belongs to the field of agricultural ploughing machines, and particularly relates to a large turnover plow. Plow walls of the large turnover plow are fixedly installed on plow poles, and plow shares are fixedly installed on the plow walls; the plow poles comprise the upper plow poles and the lower plow poles, the upper plow poles and the lower plow poles are symmetrically and fixedly installed on a plow frame through connecting plates, the quantity of the upper plow poles and the quantity of the lower plow poles are equal and are 2-15, the upper plow poles and the lower plow poles are sequentially, symmetrically and fixedly installed on the plow frame at intervals from the end, close to a traction frame, of the plow frame, the heights of the upper plow poles and the heights of the lower plow poles are decreased progressively according to arithmetic progression, and the tolerance ranges from 0.5 cm to 2.0 cm, wherein the heights of the plow poles are the distances between the planes of all colters and the plane of the center of the plow frame, the plane of each colter is the plane formed by the first tip of the corresponding plow share, the second tip of the plow share and one point of one end of a balance plate, and the end of the balance plate is the end which is not connected with the corresponding plow wall. The ploughing depth is always consistent and adjustable, flat ploughing is achieved, labor is saved, and the working efficiency is high.

Description

[0001] Technical field: [0002] The invention belongs to the field of agricultural tillage machinery, in particular to a large reversing plow. [0003] technical background: [0004] As a traditional agricultural machinery, the reversing plow has served agriculture for a long time, but all reversing plows have a disadvantage—the length of the front and rear plow columns of the reversing plow is equal, and the planes of the front and rear rows of plowshares are all in the same plane, resulting in arable land The depth is inconsistent, laborious and has a great impact on agricultural output, and the ground of cultivated land is uneven. In order to solve the problem of the depth of cultivated land, the existing reversing plow makes the plow share into a curved surface that bends downwards, which causes the plow share to be easily damaged and has little influence on the depth of cultivated land.
