[0024] 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.

[0025] First embodiment:

[0026] See also Figure 1-Figure 2 As shown, the utility model provides an extremely wear-resistant bucket tooth for mining, comprising a wear-resistant tooth-shaped layer 1, a tooth groove 101 is provided on the side of the wear-resistant tooth-shaped layer 1 facing the bucket, a pin hole connected to the bucket is penetrated on the tooth groove 101, a bottom support portion 102 is provided on the side of the wear-resistant tooth-shaped layer 1 facing the bucket, and the bottom support portion 102 is located below the bucket; a connecting plate 3 is provided inside the wear-resistant tooth-shaped layer 1, a connecting hole 301 is provided on the connecting plate 3, and a skeleton plate 4 is connected to the upper and lower sides of the connecting plate 3, and the skeleton plates 4 located above and below the connecting plate 3 are staggered;

[0027] After the skeleton plate 4 is connected to the connecting plate 3, the upper skeleton plate 4 and the connecting plate 3 form a "U"-shaped structure, and the lower skeleton plate 4 and the connecting plate 3 form an inverted "U"-shaped structure. In the device structure, the connecting plate 3 and the skeleton plate 4 form a skeleton that supports the wear-resistant tooth-shaped layer 1, so that the wear-resistant tooth-shaped layer 1 as a whole is not easy to deform. After the wear-resistant tooth-shaped layer 1 is processed and set with the connecting plate 3 and the skeleton plate 4 by casting, the connecting plate 3 and the wear-resistant tooth-shaped layer 1 can be better connected by using the connecting hole 301. During the use of the device, when the wear-resistant tooth-shaped layer 1 contacts with the material, the wear-resistant effect is better, and the support of the wear-resistant tooth-shaped layer 1 by the connecting plate 3 and the skeleton plate 4 is used to form a supporting skeleton, which has a better supporting effect and can disperse the stress of the bucket teeth during excavation, thereby improving the working efficiency and service life of the excavator.

[0028] An upper groove 104 is provided on the wear-resistant tooth-profile layer 1. The upper groove 104 is an arc-shaped structure in the transverse and longitudinal directions of the wear-resistant tooth-profile layer 1. The upper groove 104 can form a structure with a concave middle portion on the upper surface of the wear-resistant tooth-profile layer 1. During use, the position where the surface of the wear-resistant tooth-profile layer 1 is first worn is on the surrounding surface of the wear-resistant tooth-profile layer 1. The convex surrounding area can reduce the overall wear resistance of the wear-resistant tooth-profile layer 1. During use, the overall wear of the wear-resistant tooth-profile layer 1 is evenly worn, avoiding frequent replacement or maintenance due to local excessive wear, thereby increasing the service life of the bucket teeth.

[0029] The outer walls of the connecting plate 3 and the frame plate 4 are shot peened to increase the friction between the connecting plate 3 and the frame plate 4, and to improve the connection effect between the wear-resistant toothed layer 1 and the connecting plate 3 and the frame plate 4, so as to achieve a good connection.

[0030] The second embodiment is different from the first embodiment in that:

[0031] A tooth seat matching layer 2 is provided on one side of the connecting plate 3 away from the working end of the wear-resistant toothed layer 1. The tooth seat matching layer 2 is in a "U"-shaped structure and is located on the outside of the bucket tooth seat. The inner wall of the tooth seat matching layer 2 is provided with a wear-resistant layer 201 in contact with the bucket tooth seat. During the use of the bucket, when the wear-resistant toothed layer 1 and the bucket seat are connected, one is to rely on the insertion of the tooth groove 101 and the bucket seat, and the other is to rely on the reinforcement of the wear-resistant toothed layer 1 with pins to achieve the installation of the wear-resistant toothed layer 1. During use, shaking will occur between the tooth groove 101 and the bucket seat. The tooth seat matching layer 2 is used to assist in the forming of the inner wall of the tooth groove 101, and cooperates with the wear-resistant layer 201 to improve the strength of the inner wall of the tooth seat matching layer 2, thereby improving the impact wear effect of the inner wall of the tooth groove 101, so as to enhance the durability of the device.

[0032] The third embodiment is different from the first embodiment in that:

[0033] In the connection of the connecting plate 3, the skeleton plate 4 is welded to the connecting plate 3, the wear-resistant toothed layer 1 and the connecting plate 3 are integrally cast, and the connecting plate 3 and the skeleton plate 4 form a skeleton structure that supports the wear-resistant toothed layer 1.

[0034] Furthermore, the end surface of the gear seat matching layer 2 facing the connecting plate 3 is an arc structure, the end of the skeleton plate 4 facing the gear seat matching layer 2 is arranged in an arc shape, and the end of the skeleton plate 4 facing the gear seat matching layer 2 is welded to the gear seat matching layer 2, so that the gear seat matching layer 2 and the skeleton plate 4 are connected and reinforced, and the overall strength of the device is improved;

[0035] In a preferred embodiment, a strip groove 103 is provided on the bottom surface of the wear-resistant tooth-shaped layer 1, and the strip groove 103 is arranged away from the working end of the wear-resistant tooth-shaped layer 1. As the bucket is pressed down and contacts the material, the strip groove 103 can form a concave structure on the bottom surface of the wear-resistant tooth-shaped layer 1. When the bucket moves laterally, part of the material can be squeezed inside the strip groove 103, which can reduce the overall wear of the material on the bottom surface of the wear-resistant tooth-shaped layer 1 in the bucket tooth, improve the wear-resistant effect of the wear-resistant tooth-shaped layer 1, and a reinforcing rib structure is formed on both sides of the strip groove 103, which can extend the service life of the bucket tooth.

[0036] 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.
