[0002] Soil tillage is an important task in agricultural production, which is very beneficial to restoring soil fertility, improving soil structure, and eliminating weeds and pests and diseases.

[0003] Currently used agricultural machines are classified into three types according to the characteristics of their working parts: moldboard plows, disc plows and rotary plows. The three existing plows generally have the following problems: 1. During farming operations, it is necessary to overcome the resistance of farmland soil. To this end, the tractors and agricultural vehicles driving the plows need to have high output power, resulting in high fuel consumption of tractors and agricultural vehicles, thereby increasing the cost of plowing farmland; 2. Problems such as slow farming operation speed.

[0004] The agricultural machinery is mainly composed of the plow body, plow frame, traction device and hooking device. Figure 1 As shown, the plow body is the main working part of the plow, generally consisting of a coulter 1, a moldboard 2, and a plow arm 3. The plow arm 3 is fixed to the plow frame through a perforation on the top, and the lower part of the plow arm 3 is fixed to the rear side of the moldboard 2. The moldboard 2 extends forward, and the intersection surface forms the edge of the coulter 1. When the plow body is used in poor soil plowing operations, the soil is accompanied by rocks, lumps, and wet soil, resulting in greater resistance to the plow head, damage to the coulter, and even breakage of the plow body.

[0005] To this end, the present application provides a moldboard plow for an agricultural machine to solve the problems in the above-mentioned background technology. Utility Model Content

[0006] The purpose of the utility model is to provide a moldboard plow for agricultural machinery, which solves the problems of large resistance of the existing plow body and breakage of the plow body when plowing poor land.

[0007] In order to solve the above technical problems, the utility model provides a moldboard plow for agricultural machinery, including a plow frame, on which are mounted several plow arms A, a plow blade A is fixed at either end of the plow arm A body, and a spring is provided at the other end. The spring adapter is mounted on the outer wall of the sleeve and is used for the deformation of the plow arm A.

[0008] A further improvement of the technical solution of the present utility model is that: one side of the plow arm A body is provided with a spring, and its arc-shaped end face extends vertically upward, and an upper fixing hole is provided at the extended portion. The upper fixing hole is adapted to install one end of the sleeve through the rotating shaft, and the other end of the sleeve is adapted to install in the lower fixing hole through the rotating shaft.

[0009] A further improvement of the technical solution of the present utility model is that the lower fixing hole is fixed to the outer wall of the plow arm A and is far away from the upper fixing hole.

[0010] A further improvement of the technical solution of the present invention is that the outer wall of the sleeve is adapted to be equipped with a spring, and a gap exists between the spring and the plow arm A, so as to facilitate the deformation of the spring.

[0011] A further improvement of the technical solution of the present utility model is that a fixing hole is provided at one end of the plow arm A body, the fixing hole is vertically located below the upper fixing hole extending upward from the arc-shaped end surface, and the fixing hole is used to connect the plow frame.

[0012] A further improvement of the technical solution of the present utility model is that the plow arm A body is arc-shaped and formed in one piece, and the plow arm A body is provided with a plurality of long through holes in the transverse and longitudinal directions.

[0013] A further improvement of the technical solution of the present utility model is that the plow A also includes special-shaped grooves, perforations and arcuate surfaces. The special-shaped grooves are symmetrically arranged in the front area of ​​the plow A, a number of perforations are arranged behind the special-shaped grooves, and an arcuate surface is arranged behind the perforations.

[0014] A further improvement of the technical solution of the present utility model is that the through hole is fixed to one end of the plow arm A by a bolt.

[0015] A further improvement of the technical solution of the present utility model is that the special-shaped groove increases the strength of the coulter A and reduces the adhesion of soil to the upper surface of the coulter A.

[0016] A further improvement of the technical solution of the present invention is that the arc of the special-shaped groove body is 10-20 degrees, which facilitates the plow A to enter the soil.

[0017] By adopting the above technical solution, the utility model has the following beneficial effects:

[0018] The present invention provides a moldboard plow for agricultural machinery. The plow arm A is equipped with a spring to increase the plow body's toughness and bending resistance. When subjected to backward resistance, the spring and sleeve on the plow arm A form a damping structure, increasing the plow arm A's bending strength and toughness and reducing the risk of breakage. The present invention provides a moldboard plow for agricultural machinery. The plow arm A is equipped with a spring. When encountering rocks and lumps, the plow arm A experiences backward resistance, which is reduced by the spring and sleeve. The plow arm A is curved, changing the direction of force applied to the coulter A and reducing damage to the coulter A. The present invention provides a moldboard plow for agricultural machinery. The plow arm A is an arc-shaped, integrally formed body. The plow arm A is an elongated structure with long transverse and longitudinal perforations. This reduces the plow body's resistance to rocks, lumps, and wet soil, thereby improving plowing efficiency. The present invention provides a moldboard plow for agricultural machinery. The plow blade A is provided with a special-shaped groove and an arcuate surface on its body, increasing the strength and toughness of the plow blade A while reducing soil adhesion to the upper surface of the plow blade A, thereby reducing the resistance of the plow body. The present invention provides a moldboard plow for agricultural machinery. The plow blade A is fixed to the plow arm A via bolts. Conventional plow blades are welded to the plow body. If part of the plow blade is damaged, the entire plow body must be replaced. However, if the plow blade A of the present invention is damaged, only the plow blade A needs to be replaced, significantly reducing the cost of plow blade replacement.
