[0021] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0022] First embodiment:

[0023] See also Figure 1-Figure 2As shown, the utility model provides a special bucket tooth suitable for cement mines, including an excavating body 1, a slot 101 for plugging and matching with a bucket tooth seat is provided on the excavating body 1, a pin hole is penetrated through the side wall of the slot 101, a wear-resistant layer 3 is provided on the outer side of the excavating body 1, and an inner support frame 2 is provided inside the excavating body 1;

[0024] The inner support frame 2 is a sheet-like structure, the end of which corresponds to the top of the slot 101, and the front section of the inner support frame 2 extends toward the working end of the excavation body 1, folding to form a triangular support structure;

[0025] When installing the device, the slot 101 is connected to the bucket tooth seat by plugging, and the slot 101 is reinforced by cooperating with the pin shaft to complete the installation of the excavation body 1.

[0026] When the device is in use, the inner support frame 2 can form support for the excavation body 1, thereby improving the overall strength of the excavation body 1. During the excavation work, the working end of the excavation body 1 will be in a compressed state. Then, inside the slot 101, the wear of the inner top surface of the slot 101 is more serious than the wear of the lower surface of the slot 101. In the present device, the inner support frame 2 is used to improve the wear resistance of the inner top surface of the slot 101, thereby reducing the wear of the upper surface of the slot 101, thereby improving the durability of the excavation body 1.

[0027] The inner support frame 2 is provided with a positioning hole 201 which is connected to the slot 101. When the excavation body 1 is processed and formed, the casting mold corresponds to the slot 101, and the inner support frame 2 can be positioned by connecting the movable insertion rod with the positioning hole 201, thereby assisting the forming of the excavation body 1 and making the inner support frame 2 correspond to the upper surface of the slot 101.

[0028] The second embodiment is different from the first embodiment in that:

[0029] The excavation body 1 includes a connecting portion 106 and a front end tooth 104. The slot 101 is arranged on the connecting portion 106. The upper surface of the connecting portion 106 is arranged obliquely. The lower end of the inclined surface is arranged away from the front end tooth 104. The top surface of the connecting portion 106 can be used to drain the mine material, which can roll down into the hopper along the upper surface of the connecting portion 106. The connecting portion 106 is provided with a guide groove 107. The bottom surface of the guide groove 107 is arranged obliquely. The lower end of the inclined surface is arranged away from the front end tooth 104. The guide groove 107 and the connecting portion 106 are in an arc transition. The connecting portion 106 can play a role in drainage, thereby reducing the loss of materials from the surface of the connecting portion 106.

[0030] In the digging structure of the front end teeth 104, side section teeth 105 are provided on both sides of the front end teeth 104. The two side section teeth 105 are respectively located on both sides of the front end teeth 104, and their thickness is thinner than the thickness of the front end teeth 104. The front end teeth 104 and the side section teeth 105 have an arc transition. One end of the side section teeth 105 is a wide surface, and the other end is a narrow surface. The wide surface faces the working end of the front end teeth 104. This arrangement increases the width of the working section of the front end teeth 104. When loading, more materials can be taken at one time, and the overall wear is smaller. The front end teeth 104 with a higher height are used to form a support for a better wear area, and the durability is higher during loading.

[0031] A supporting portion 102 is provided on the side of the connecting portion 106 away from the front end tooth 104. The supporting portion 102 is located below the slot 101 and extends to the bottom of the bucket. A groove 103 is provided on the upper surface of the supporting portion 102, and a threaded hole is provided on the bottom surface of the groove 103. As the device is used, the connecting portion 106 is connected to the bucket tooth seat by a pin shaft, and the front end tooth 104 has a downward gravity. Among them, when the inner wall of the slot 101 is in contact with the bucket tooth seat, the wear on the upper surface of the slot 101 is more serious than the wear on the lower surface of the slot 101. The use of the inner support frame 2 can slow down the wear on the upper surface of the slot 101, but wear will still occur. The contact between the supporting portion 102 and the bottom of the bucket forms a support for the bucket tooth. Furthermore, a bolt is installed in the screw hole, and the high end of the bolt contacts the bottom of the bucket to form a support for the excavation body 1, thereby improving the durability of the excavation body 1.

[0032] The front end teeth 104, the connecting portion 106, the side segment teeth 105 and the supporting portion 102 are integrally cast.

[0033] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
