AI Technical Summary
Existing agricultural machinery plows are prone to damage when working in soft soil mixed with hard soil and gravel, leading to loose connections and worn bolts, which affects work efficiency and service life.
A high-strength plowshare is designed, which uses a carbide layer to reinforce the working part and the mounting part, combined with a limiting groove and a protective mechanism, and is fixed by bolts to improve wear resistance and stability.
It enhances the wear resistance and stability of the plowshare, extends its service life, improves work efficiency, and reduces replacement costs.

Abstract
Claims
1. A high-strength plow for agricultural work, comprising a long strip-shaped plow body, characterized in that: The plow body (1) is composed of an integrally set working part (2) and an installation part (3). The working part (2) is provided with a working head (4) on the side away from the installation part (3). A matching hard alloy layer (5) is welded on both the working part (2) and the working head (4) to improve the strength and wear resistance of the working head (4). The side of the installation part (3) away from the working part (2) is bent upward, so that the plow body (1) is arc-shaped. The installation part (3) is provided with a limiting groove (6). At least one assembly hole is opened in the limiting groove (6). A protective mechanism is provided at the assembly hole. After the agricultural machinery is inserted into the installation part (3), it is limited by the limiting groove (6) and the bolt is inserted into the assembly hole to realize the installation and fixation between the plow body and the agricultural machinery.
2. The high strength agricultural implement share of claim 1, wherein: The working part (2) has an overall figure-eight structure. A hard welding rod wear-resistant layer (7) with a figure-eight structure is welded at the connection between the working part (2) and the mounting part (3). The hard welding rod wear-resistant layer (7) is adjacent to the hard alloy layer (5) of the working part (2) and is used to improve the overall strength and wear resistance of the plow head body (1). The side of the working part (2) away from the mounting part (3) is inclined downward to form a first slope surface (8) that is symmetrical on both sides. Between the two first slope surfaces (8), the end of the working part (2) is recessed inward to form an assembly groove (9) for placing the working head (4). The working head (4) is embedded in the assembly groove (9) and partially exposed outside the assembly groove (9) to facilitate soil breaking, thereby improving the working efficiency of the working head (4).
3. The high strength agricultural implement share of claim 2, wherein: The height of the upper surface of the working head (4) on the side away from the working part (2) is less than the height on the other side, forming a sloping second slope surface (10). The second slope surface (10), the first slope surface (8) and the upper surface of the working part (2) are all welded with a hard alloy layer. The hard alloy layer (5) is composed of one or more hard alloy pieces.
4. The high strength agricultural implement share of claim 3, wherein: The mounting part (3) is provided with a long strip-shaped limiting groove (6) in the middle position. Three assembly holes are provided in the front, middle and rear positions of the limiting groove (6), namely a circular assembly hole (11), a long strip-shaped assembly hole (12) and an elliptical assembly hole (13). A protective mechanism is provided on the side of the circular assembly hole (11) facing the working part.
5. The high strength agricultural implement share of claim 4, wherein: The protective mechanism is a V-shaped hard alloy bump (14), which is set on the edge of the circular mounting hole (11) and encloses half of the circular mounting hole (11) to protect the circular mounting hole (11) and prevent the bolts in the circular mounting hole (11) from wearing out prematurely, so as to loosen the connection between the plow head body and the agricultural machinery.
6. The high strength agricultural implement share of claim 4, wherein: The outer side of the elongated limiting groove (6) is provided with wavy concave and convex surfaces (15) at both sides of the mounting part to improve the wear resistance and aesthetics of the mounting part (3).
7. The high-strength agricultural machinery plowshare according to claim 5, characterized in that: The circular assembly hole (11), the elongated assembly hole (12), and the elliptical assembly hole (13) are respectively composed of bolt holes (16) and square countersunk holes (17) with the same center.
