Technical Field
[0001] The utility model belongs to the technical field of tree stump crushers, and in particular relates to teeth for a tree stump crusher. Background Art
[0002] The stump crusher mainly uses the stump crusher teeth to directly contact the stumps for cutting. Therefore, the teeth of the stump crusher need a certain hardness. The current teeth generally adopt a steel structure, so during use, they are prone to wear resistance and need to be replaced frequently, which affects the work progress and increases the cost of use. In addition, due to vibrations during work, the connection between the teeth and the crusher will become loose, affecting work efficiency and bringing certain safety hazards. For this reason, a stump crusher tooth is designed to overcome the above problems. Utility Model Content

[0004] The utility model is realized through the following technical scheme: a stump crusher tooth, which includes a tooth body, the tooth body is in a gold ingot-shaped structure, and is composed of a working part at the top and a mounting part at the bottom, a limit assembly groove in an inverted V-shaped structure is provided on the mounting part at the bottom, a through hole penetrating the working part and the mounting part is provided in the middle of the limit assembly groove, the through hole is located on one side of the working part and is embedded in a groove of a square structure provided on the working part, the groove is used to place bolts, a working tooth head is provided around the square groove, and a hard alloy layer is welded on the working tooth head.
[0005] Preferably, the bottom of the working part is an arc-shaped structure, and the two sides of the arc-shaped structure are inclined upward to form an eight-shaped structure. A recessed area is opened at the end of the inclined edges on both sides to facilitate positioning and installation. Working tooth heads are installed on both side edges of the arc-shaped structure, and the working tooth heads are arranged in a mirror image.
[0006] Preferably, the working tooth head is in an M-shaped structure, with the two protruding ends at the front being the working heads, a hard alloy layer is welded on or below each protruding working head, and a reinforcing rib is installed in the middle of the M-shaped working tooth head to prevent the working tooth head from breaking during operation.
[0007] Preferably, both side edges of the mounting portion are provided with concave positioning edges.
[0008] The beneficial effects of the utility model are as follows:
[0009] The stump crusher teeth designed by the utility model adopt a high-strength and highly wear-resistant hard alloy layer working tooth head in the working part, and the ingot-shaped design of the two ends greatly improves the service life of the product, overcomes the technical deficiencies of the original single working surface, and causes the problem of structural damage and frequent replacement of the tooth head, and the overall cutting effect is better and more stable. The limit assembly groove of the inverted V-shaped structure of the tooth head body in the utility model is used for limiting and assembly, and the through hole that runs through the working part and the mounting part is used for bolt fixing. The utility model as a whole has many advantages such as reasonable structure, easy use and installation, good overall tooth head installation firmness, greatly improved service life, reduced use costs, and improved work efficiency.

[0013] In order to enable ordinary technicians in the field to more clearly understand the purpose, technical solutions and advantages of the utility model, the utility model is further explained below in conjunction with the accompanying drawings and embodiments.
[0014] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "horizontal" and "vertical" are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention. They do not indicate or imply that the device or component referred to must have a specific direction and therefore should not be understood as a limitation on the present invention.
[0015] The utility model will be described in detail below with reference to the accompanying drawings: Figure 1-3 As shown, a stump crusher tooth includes a tooth body 1, which is in the shape of a gold ingot, and is composed of a working part 2 at the top and a mounting part 3 at the bottom. A limit assembly groove 4 in an inverted V-shaped structure is provided on the mounting part 3 at the bottom, and a through hole 5 penetrating the working part 2 and the mounting part 3 is provided in the middle of the limit assembly groove 4. The through hole 5 is located on one side of the working part 2 and is embedded in a square groove 11 provided on the working part 2. The groove 11 is used to place bolts, and a working tooth head 6 is provided around the square groove, and a hard alloy layer 7 is welded on the working tooth head 6.
