Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery tillage plowing technology, and relates to a blade for agricultural machinery tillage plowing. Background Technology

[0002] Agricultural machinery refers to all kinds of mechanical equipment used in agricultural production. Plow blades can be installed on agricultural machinery for tilling operations. Currently, the plow blades on agricultural machinery are generally made of pure hardened steel, and the plow head generally comes into direct contact with the soil and loosens the topsoil. Although most soil is soft, it contains some hard soil and gravel. Because the working surface of the existing plow head lacks a protective structure, prolonged use and collisions with the hard soil and gravel can easily lead to damage and deformation. Vibration during plowing operations can cause the connection between the plow blade and the agricultural machinery to loosen, greatly affecting work efficiency and even causing the plow blade to fall off. Therefore, a new plow blade for agricultural machinery 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 a plow blade for agricultural machinery that has a simple and reasonable structure, beautiful design, convenient installation and disassembly, long service life, high strength and high wear resistance.

[0004] This utility model is achieved through the following technical solution: a blade for a tillage plow, comprising a blade body mounted on a tillage plow, the blade body consisting of a handle, side blades, and a blade head. One side of the handle is mounted on the tillage plow, and the blade head is welded to the other end. A hard alloy layer is welded to the blade head to improve soil breaking efficiency. A side blade is welded to the side of the handle near the blade head. The opposite sides of the side blade are folded along the center line towards the side opposite to the handle, making the side blade have an overall V-shaped structure. Hard alloy strips and hard welding rod wear-resistant layers are welded to the opposite inner surfaces of the side blade to improve the strength and wear resistance of the side blade. After the blade head breaks the soil, the side blade is used for tilling.

[0005] Preferably, the handle is a long strip structure, with the side of the handle away from the blade head recessed inward to form a mounting groove, and the opening of the mounting groove is V-shaped to facilitate the limiting installation between the handle and the tillage plow.

[0006] Preferably, the width of the cutter head is greater than the width of the handle, and the side of the cutter head away from the handle is inclined downward to form a slope surface to facilitate soil breaking. A hard alloy layer is welded on the slope surface and both sides of the cutter head to improve the overall strength of the cutter head.

[0007] Preferably, hard alloy strips are welded to the two opposite inner surfaces of the side blade near the edge, and hard welding rod wear-resistant layers are welded to the two opposite inner surfaces near the center line to improve the strength and wear resistance of the side blade and ensure the plowing effect of the side blade.

[0008] Preferably, the vertical height of the side blade is higher than that of the handle, which facilitates the use of the side blade in conjunction with the blade head for plowing.

[0009] The beneficial effects of this utility model are as follows:

[0010] The blade of this agricultural tillage plow has been changed from the original pure steel plow blade to a blade head and side blade plate made of high-strength, high-wear-resistant cemented carbide. A high-strength, high-wear-resistant hard welding rod overlay layer is also used on the side blade plate surface to enhance surface strength and wear resistance. Together with the cemented carbide, this layer protects the blade head and side blade plate, greatly improving product lifespan and work efficiency. It also reduces the need for installing and disassembling the plow blade. A limiting groove is designed in the handle for easy fixing to the tillage plow. Overall, this invention is easy to use and install, has good sturdiness, a reasonable structure, high hardness, and high wear resistance, thus greatly improving work efficiency.

[0015] To enable those skilled in the art to more clearly understand the purpose, technical solution and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "horizontal", and "vertical" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0017] The present invention will now be described in detail with reference to the accompanying drawings: Figure 1-2 As shown, a blade for a tillage plow includes a blade body mounted on the tillage plow. The blade body consists of a handle 1, side blades 2, and a blade head 3. One side of the handle 1 is mounted on the tillage plow, and the blade head 3 is welded to the other end. A hard alloy layer 4 is welded onto the blade head 3 to improve soil breaking efficiency. A side blade 2 is welded to the side of the handle 1 near the blade head 3. The opposite sides of the side blade 2 are folded along the center line towards the side opposite to the handle 1, making the side blade 2 have an overall V-shaped structure. Hard alloy strips 5 and hard welding rod wear-resistant layers 6 are welded to the opposite inner surfaces of the side blade 2 to improve the strength and wear resistance of the side blade 2. After the blade head 3 breaks the soil, the side blade 2 is used to plow the land.

[0018] like Figure 3-4 As shown, the handle 1 is a long strip structure. The side of the handle 1 away from the blade head 3 is recessed inward to form a mounting groove 7, and the opening 9 of the mounting groove 7 is V-shaped to facilitate the positioning and installation between the handle and the tillage plow. The width of the blade head 3 is greater than the width of the handle 1, and the side of the blade head 3 away from the handle 1 is inclined downward to form a slope surface 8 to facilitate soil breaking. Hard alloy layers 4 are welded to the slope surface 8 and both sides of the blade head 3 to improve the overall strength of the blade head 3. Hard alloy strips 5 are welded to the opposite inner surfaces of the side blade plate 2 near the edges, and hard welding rod wear-resistant layers 6 are welded to the opposite inner surfaces near the center line to improve the strength and wear resistance of the side blade plate 2 and ensure the tillage effect of the side blade plate 2.

[0019] The blade of the agricultural plow designed in this utility model has been changed from the original pure steel plow blade to a blade head and side blade plate made of high-strength and high-wear-resistant cemented carbide. The side blade plate surface is also formed by high-strength and high-wear-resistant hard welding rod overlay technology to enhance the surface strength and wear resistance. Together with the cemented carbide layer, it protects the blade head and side blade plate, improves the overall strength and wear resistance, and thus improves the overall working efficiency.

[0020] The side blade 2 is higher in height than the handle 1, which facilitates the use of the side blade 2 in conjunction with the blade head 3 for plowing. This invention is easy to use and install, has good stability, a reasonable structure, high hardness, and high wear resistance, thus greatly improving work efficiency.
