Embodiment Construction

[0023] like figure 2 , 3 As shown, a variable-curvature mower plow includes a plowshare 1, a plowboard 2, a plow holder 3, a plow side plate 4 and a plow post 5. It is fixedly connected with the plow column 5, and a plow side plate 4 is arranged on the plow holder 3 along the direction of the plow plow.

[0024] Among them, the upper surface of the plow share 1 and the plow wall 2 constitutes a curved surface of the plow body that touches the soil, and the curved surface of the plow body is formed by the continuous movement of the straight element line 7 parallel to the horizontal plane on the curved wire 6 according to a certain element line angle. , the curved wire 6 is given by the parametric equation , where the value range of x is 0~18. Further, the curved wire 6 is a curve segment obtained by scaling the same ratio in the x and f(x) directions respectively within the range of x from 0 to 18 mm.

[0025] like Figure 5 As shown, it is the parametric equation curve ...

Abstract

The invention relates to a furrow plow with a variable camber. The furrow plow comprises a plow standard, a plow share and a plow wall connected with the plow share, wherein a plow shoe is arranged on the lower surface, connected with the plow wall, of the plow share; the plow shoe is fixedly connected with the plow standard; a plow body and soil contact curved surface is formed by the upper surfaces of the plow share and the plow wall; the plow body and soil contact curved surface is a curved surface formed by continuous motion of a straight element parallel to the horizontal plane on a bent wire in an element angle; the bent wire accords with the equation f(x)=0.0008x<4>-0.0406x<3>+0.7596x<2>-7.2044x+0.4422, wherein x is within the value range of 0 to 18. In the furrow plow, the plow body and soil contact curved surface formed by the bent wire can change the motion state of soil on the contact surface, the original motion state that sliding contact is in a dominant position is changed into that rolling contact is primary, and the resistance and adhesion of soil to the plow body and soil contact curved surface are reduced.

Description

technical field [0001] The invention relates to the field of agricultural land machinery, in particular to a variable-curvature conventional plow. Background technique [0002] Farming machinery is a machine that mechanically treats farmland soil to make it suitable for crop growth. The main operating machines used to plow the land include conventional plows and disc plows. The plow is the earliest, largest and most widely used farming tool in the world. The plowshare and the plow wall are used as the main working parts for plowing and crushing operations. After operation, the soil is loose and broken, and it has a strong adaptability to heavy clay soil, wasteland and land with many weeds, and bears the heavy responsibility of plowing. However, in the process of tillage, especially in the heavy clay soil, the plow body formed by the traditional parabolic surface adheres seriously to the soil, resulting in high working resistance, long stroke of the plow into the soil, weak ...
