Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery plow head technology, and relates to an agricultural machinery plow head with agricultural machinery working teeth. Background Technology

[0002] Agricultural machinery refers to all kinds of mechanical equipment used in agricultural production. These machines can be equipped with tillage blades or plowshares for operation. Currently, plowshares on agricultural machinery are generally made of pure hardened steel. Since the plowshare directly contacts the soil and loosens the topsoil, although the soil is mostly soft, it contains some hard soil and gravel. Because the working surface of existing plowshares lacks a protective structure, prolonged use and collisions with hard soil and gravel can easily lead to damage and deformation. Vibration during plowing can cause the connection between the plowshare and the machinery to loosen. Furthermore, the existing bolt holes lack protective structures, and the plow's operation accelerates bolt wear, leading to loose connections that significantly affect work efficiency or even cause the plowshare to fall off. Therefore, a plowshare with working teeth is designed to overcome these problems. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an agricultural plowshare with agricultural machinery working teeth that has a reasonable structure, stable assembly, good firmness, convenient installation and disassembly, high hardness and high wear resistance, and greatly improves working efficiency and service life.

[0004] This utility model is achieved through the following technical solution: a plowshare with working teeth, comprising a block-shaped plowshare body, the two ends of which are inclined upwards to form a raised head and a tail, respectively. A working head is provided on the head, and matching hard alloy layers are welded on the working head, the upper surface of the head, and the two sides to improve the overall strength of the working head and the head. At least one vertical mounting hole penetrating the tooth body is provided on the tail, and a protective device is provided at each mounting hole. After inserting the agricultural machinery into the tail, the plowshare body is fixed to the agricultural machinery by installing bolts in the mounting holes.

[0005] Preferably, the working head and the head are rectangular and trapezoidal structures, respectively. The working head is located in the middle of the head and partially exposed to improve working efficiency. The hard alloy layer is a single piece or multiple pieces, welded to the upper surface and both sides of the working head and the head. A hard welding rod wear-resistant layer is welded to the upper surface of the plow body at the connection between the head and the tail to improve the strength and wear resistance of the plow body.

[0006] Preferably, the protective device is a V-shaped hard alloy bump, which is set on the edge of each mounting hole, covering half of the mounting hole, to protect the mounting hole and prevent the bolts in the mounting hole from wearing out prematurely, so as to prevent the connection between the plow head body and the agricultural machinery from becoming loose.

[0007] Preferably, there are two mounting holes of the same size, arranged in a front-to-back pattern, and each mounting hole consists of a circular bolt hole and a square countersunk hole with the same center.

[0008] Preferably, the outer side of the assembly hole is provided with a wavy concave-convex surface on the upper surface of the tail. The concave-convex surface is evenly or symmetrically distributed on the upper surface of the tail, enclosing the two assembly holes, which improves the overall aesthetics and wear resistance.

[0009] Preferably, the lower surface of the tail section is recessed inward to form an assembly groove, and downwardly extending and symmetrically arranged limiting posts are respectively provided on both sides of the lower surface of the tail section. The two limiting posts and the assembly groove form a limiting device for limiting the agricultural machinery when it is inserted into the tail section.

[0010] Preferably, the opening of the mounting groove facing the tail is in a figure-eight shape, which serves as a guide to facilitate the insertion of the agricultural machinery into the tail of the plow head body.

[0011] Preferably, the angle of inclination of the tail is smaller than that of the head, which facilitates assembly and operation of the working head.

[0012] The beneficial effects of this utility model are as follows: The agricultural plowshare with working teeth designed in this utility model is changed from the original pure alloy steel working teeth / plowshare to high-strength, high-wear-resistant hard alloy inlaid on the upper surface and sides of the head and working head (tooth tip). At the connection between the tail and the head, a high-strength and high-wear-resistant hard welding rod is used to build up a hard welding rod wear-resistant layer on the upper surface of the plowshare body, which enhances the surface strength and wear resistance, protects the body, and reduces the cost of replacing subsequent blades. The agricultural plowshare body is fixed with two positioning holes and limit slots, making its assembly stable and firm. A V-shaped high-strength, high-wear-resistant hard alloy is inlaid on the edge of the assembly hole to protect the bolts and prevent premature wear of the bolts, which would cause the teeth / plowshare to fall off, thus improving the service life of the product. The wavy concave-convex surface design of the agricultural plowshare body of this utility model improves the wear resistance of the product and also enhances the product's appearance. It has the advantages of reasonable structure, convenient installation and disassembly, long service life, high hardness and high wear resistance, which greatly improves work efficiency.

[0018] The present invention will now be described in detail with reference to the accompanying drawings: Figure 1 As shown, a plowshare with working teeth includes a block-shaped plowshare body 1. The two ends of the plowshare body 1 are inclined upwards, forming a raised head 2 and a tail 3 respectively. A working head 4 is provided on the head 2, and matching hard alloy layers 5 are welded to the upper surface and both sides of the working head 4 and the head 2 to improve the overall strength of the working head 4 and the head 2. At least one mounting hole 5 is provided on the tail 3, which is perpendicular to the tooth body, and a protective device is provided at each mounting hole 5. After the agricultural machinery is inserted into the tail 3, the plowshare body 1 is fixed to the agricultural machinery by installing bolts in the mounting holes 5.

[0019] like Figure 2-3 As shown, the working head 4 and the head 2 are rectangular and trapezoidal structures, respectively. The working head 4 is located in the middle of the head 2 and is partially exposed to improve the working efficiency. The hard alloy layer 5 is a single piece or multiple pieces, welded to the upper surface and both sides of the working head 4 and the head 2. At the connection between the head 2 and the tail 3, a hard welding rod wear-resistant layer 6 is welded to the upper surface of the agricultural machinery plow body 1 to improve the strength and wear resistance of the agricultural machinery plow body 1.

[0020] The agricultural plowshare with working teeth designed in this utility model has been changed from the original pure alloy steel working teeth / plowshare to high-strength and high-wear-resistant hard alloy inlaid on the upper surface and side of the head and working head (tooth tip). At the connection between the tail and the head, a hard wear-resistant layer is formed on the upper surface of the plowshare body by high-strength and high-wear-resistant hard welding rod overlay technology, which enhances the surface strength and wear resistance, protects the body, and reduces the cost of replacing subsequent blades.

[0021] The protective device is a V-shaped hard alloy protrusion 7. The hard alloy protrusion 7 is set on the edge of each mounting hole 5, covering half of the mounting hole 5. It is used to protect the mounting hole 5 and prevent the bolts in the mounting hole 5 from wearing out prematurely, so as to loosen the connection between the plow head body 1 and the agricultural machinery.

[0022] There are two assembly holes 5, which are the same size and arranged in a front-to-back pattern. Each assembly hole 5 consists of a circular bolt hole 8 and a square countersunk hole 9 with the same center. The outer side of the assembly hole 5 is provided with a wavy concave-convex surface 10 on the upper surface of the tail 3. The concave-convex surface 10 is evenly or symmetrically distributed on the upper surface of the tail 3, which encloses the two assembly holes 5 to improve the overall aesthetics and wear resistance.

[0023] The plowshare body of this invention is fixed with two positioning holes and a limiting groove, ensuring stable assembly and good firmness. A V-shaped high-strength, high-wear-resistant carbide insert is designed and inlaid along the edge of the assembly holes to protect the bolts, preventing premature wear and tooth / plowshare loss, thus extending the product's service life. The wavy, textured surface design of the plowshare body further enhances the product's wear resistance and aesthetics.

[0024] The lower surface of the tail section 2 is recessed inward to form an assembly groove 11. On both sides of the lower surface of the tail section 2, downwardly extending and symmetrically arranged limiting posts 12 are respectively provided. The two limiting posts 12 and the assembly groove 11 form a limiting device, used to limit the insertion of the agricultural machinery into the tail section 3. The opening 13 of the assembly groove 11 facing the tail section 3 has a V-shaped structure, serving as a guide to facilitate the insertion of the agricultural machinery into the tail section 3 of the plow head body. The tilt angle of the tail section 3 is smaller than that of the head section 2, facilitating assembly and operation of the working head 4.

[0025] The plowshare with agricultural machinery working teeth designed in this utility model has the advantages of reasonable structure, convenient installation and disassembly, long service life, high hardness and high wear resistance, which greatly improves work efficiency.
