Drawings

Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1, the plowshare in the embodiment includes a plate-shaped body 1, and the lower portion of the body 1 is gradually bent forward, so that the plate surface of the body 1 is in an L shape with a bending transition as a whole. When in use, the body 1 is in a vertical state, and the thickness surface of the body 1 forms an action surface.

In this embodiment, the front end surface 101 and the rear end surface 102 of the body 1 are both thickness surfaces, and the front end surface 101 and the rear end surface 102 of the body 1 are connected at the lower end to form the cut-in portion 11 with a V-shaped vertical cross section, so that the contact section area of the plowshare and the soil is very small, and the plowshare can be conveniently and smoothly pricked into the deep soil.

The width of the upper portion of the front end surface 101 of the main body 1 is smaller than the width of the lower portion, so that the upper portion of the front end surface 101 of the main body 1 is substantially linear, and the front end of the horizontal cross section of the upper portion of the main body 1 is V-shaped. So make the contact tangent plane area of the top of preceding terminal surface 101 of ploughshare and soil contact very little at the in-process that moves ahead, and then the ploughshare ploughs the back, and the upper portion of soil only leaves thinner gap, avoids the soil of upper portion to turn up, simultaneously, leaves the lower part of ploughshare and carries out effectual loose to soil, so on reaching the basis of loosening the soil, effectively remain the moisture in the soil, reduce the evaporation of water in the soil, do not destroy the soil structure.

The front end face 101 of the body 1 is provided with at least three sequentially continuous plane sections with different included angles with a horizontal plane from bottom to top, the included angle between a first plane section 12 at the lowest end and the horizontal plane is A, the included angle between a second plane section 13 which is positioned at the upper end of the first plane section 12 and is connected with the first plane section 12 and the horizontal plane is B, the included angle between each third plane section 14 positioned at the upper end of the second plane section 13 and the horizontal plane is C, wherein B is less than A and less than C, the included angle between the first plane section 12 and the second plane section 13 and the horizontal plane enables the front end of the body 1 to more forcefully penetrate into soil, and the included angle between the third plane and the horizontal plane can reduce the eversion effect on the soil as much as possible so as to retain the water content of the soil.

According to requirements, the included angle between each plane section and the horizontal plane can be more than or equal to 20 degrees and less than 90 degrees, more than or equal to 0 degrees and less than 90 degrees, and the C is less than or equal to 90 degrees. In the present embodiment, a is 60 ° and B is 30 °. In order to further reduce the eversion of the soil, at least two third plane sections 14 are sequentially and continuously arranged upwards at the upper end of the second plane section 13, the included angle between each third plane section 14 and the horizontal plane is gradually increased along the upward direction, the third plane sections 14 in the embodiment are provided with three sections, wherein the included angle between the third plane section 14 connected with the second plane section 13 and the horizontal plane is 75 degrees, and the included angle between the remaining two third plane sections 14 and the horizontal plane is 90 degrees.

The front end face 101 of the body 1 is provided with a wear resistant layer 20. The wear-resistant layer 20 is formed by fixedly arranging wear-resistant pieces 2 on the surface of each plane section respectively, and the wear-resistant pieces 2 can be made of hard alloy pieces. On one hand, the action strength of the plowshare to the soil can be improved, and on the other hand, the service life of the plowshare can be prolonged.

The upper end of the plowshare is provided with the mounting hole, and then the plowshare can be installed and applied to a cultivator through the mounting hole, the cultivator can drive the plowshare to work, after the cultivator starts to work, the plowshare is inclined forwards firstly to apply force downwards, then the lower end of the plowshare continuously extends into soil until the plowshare is basically and completely arranged in the soil, and the plowshare can be quickly and smoothly cut into the soil due to the fact that the front end of the plowshare is the V-shaped cut-in portion 11. Along with the advance of arable land machine, the ploughshare can be fine loosen soil to because the upper portion width of ploughshare front end face 101 is little, make the area of contact with soil very little, be the threadiness basically, avoid the ploughshare to cause the soil on surface to turn up, the ploughshare in this embodiment back of passing through, the soil surface keeps the original state basically except the gap that the ploughshare passes through, the condition of turning up of the soil is reduced greatly, make soil keep the original state basically on more loose basis, so then effectively remain the moisture in the soil, reduce the evaporation of water in the soil, do not destroy soil structure.
