Description

Technical Field

[0001] This utility model belongs to the field of topsoil loosening machine technology, specifically relating to the teeth of a topsoil loosening machine. Background Technology

[0002] The topsoil loosening machine tooth head mainly utilizes multiple hardened teeth to directly contact the soil and loosen the topsoil. Although most soil is soft, it contains some hard soil and gravel. Therefore, the loosening machine teeth need a certain degree of hardness, especially on the surface in contact with the soil. However, since the existing machine heads are made of steel, they are prone to wear during use, requiring frequent tooth replacement, which affects the work process and increases operating costs. Furthermore, the strong vibrations generated during operation can cause the connection between the tooth head and the cutter holder of the topsoil loosening machine to loosen, affecting work efficiency and creating safety hazards. Therefore, a new topsoil loosening machine tooth is designed to overcome the above problems. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a topsoil loosening machine tooth with a simple and reasonable structure, convenient installation and use, good stability, high wear resistance and impact resistance, and greatly improved work efficiency.

[0004] This utility model is achieved through the following technical solution: a topsoil loosening machine tooth, comprising a block-shaped working tooth, the working tooth being composed of an integrally formed assembly part and a working part, wherein at least one mounting groove is provided at the end of the working part away from the assembly part, and a hard alloy block is embedded and welded into the mounting groove to serve as a working head for operation; an assembly groove is formed by an inward recess in the middle of the end of the assembly part away from the working part, and mounting holes penetrating the assembly part are respectively opened on the opposite side walls of the assembly groove; the mounting groove is inserted into the loosening machine, and then fixed by bolts inserted into the mounting holes; the thickness of the assembly part is greater than the thickness of the working part, and the assembly part and the working part are connected by an arc-shaped transition edge, and the working part, the assembly part, and the mounting groove on the assembly part are all on the same center line to ensure the overall stability after installation.

[0005] Preferably, the left and right ends of the working part are provided with symmetrically arranged mounting grooves, and a cemented carbide block is embedded and welded into each mounting groove. The cemented carbide block is partially exposed outside the mounting groove, and the exposed part is pointed, which is used to improve the overall working efficiency.

[0006] Preferably, the diameter of the assembly part at the end away from the working part gradually increases, making the assembly part into a trapezoidal structure. Two assembly holes of the same size are opened on the upper and lower surfaces of the assembly part away from the working part near the two ends. The four assembly holes are respectively matched with the assembly groove to ensure the overall stability of the crusher and the working teeth after installation.

[0007] Preferably, the assembly part has arc-shaped protective edges at both ends away from the working part.

[0008] Preferably, the mounting hole consists of concentric circular screw holes and circular countersunk holes, with the diameter and depth of the circular countersunk holes being greater than those of the circular screw holes to ensure overall stability after installation.

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

[0010] The surface soil loosening machine teeth designed in this utility model employ two large, highly wear-resistant and impact-resistant cemented carbide plates as the main crushing components. This dual-head, large-plate cemented carbide design significantly extends the product's service life and overcomes the shortcomings of previous single-face and small-plate cemented carbide technologies, which resulted in frequent head damage and replacements. Furthermore, the large-plate cemented carbide plates provide better and more stable crushing performance. The assembly section of this utility model features a U-shaped assembly groove for positioning, with two positioning holes at the top and bottom of the groove for bolt fixation, ensuring overall stability after installation and preventing displacement due to vibration during operation. This utility model boasts a reasonable overall structure, excellent robustness, and convenient installation and use. The dual-head, large-plate cemented carbide structure offers high operating efficiency, long service life, high impact resistance, and high wear resistance, thereby significantly improving work efficiency.

[0013] 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.

[0014] 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.

[0015] The present invention will now be described in detail with reference to the accompanying drawings: Figure 1-2 As shown, a topsoil loosening machine tooth includes a block-shaped working tooth, which is composed of an integrally formed assembly part 1 and a working part 2. At least one mounting groove 3 is provided at the end of the working part 2 away from the assembly part 1. A hard alloy block 4 is embedded and welded into the mounting groove 3 to perform work as a working head. An assembly groove 5 is formed by inward indentation in the middle of the end of the assembly part 1 away from the working part 2. Assembly holes 6 that penetrate the assembly part are respectively opened on the opposite side walls of the assembly groove 5. The assembly groove is inserted into the loosening machine, and then fixed by bolts inserted into the assembly holes 6.
