[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4 The utility model provides a technical solution: an excavator bucket tooth that is easy to adjust, comprising: a tooth root 1, a tooth tongue 2, a mounting block 3, a first mounting rod 4, a supporting spring 5, a limit frame 6, a connecting plate 7, a supporting frame 8, a connecting block 9, a connecting shaft 10, a second mounting rod 11 and a bucket tooth body 12;

[0026] First, as attached Figure 1 As shown in the figure, the mounting block 3 is mounted on the outside of the tooth tongue 2, and then the bucket tooth body 12 is mounted on the outside of the mounting block 3 by a mounting mechanism composed of a connecting plate 7, a connecting block 9, a connecting shaft 10 and a second mounting rod 11. When the angle of the bucket tooth body 12 needs to be adjusted, it is fixed by a limiting mechanism composed of a supporting spring sheet 5 and a limiting frame 6;

[0027] As attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown in the figure, the mounting block 3 and the tooth root 1 are tightly fitted, so that the mounting block 3 and the tooth tongue 2 fixed below the tooth root 1 are connected by a slot, and the first mounting rod 4 is threadedly connected with the tooth tongue 2 and the mounting block 3 to fix the tooth tongue 2 and the mounting block 3, and then the connecting shaft 10 is inserted into the mounting block 3, and then the limit frame 6 is pressed inwardly to make the limit frame 6 compress the supporting spring piece 5 and receive it in the mounting block 3. The limit frame 6 is completely connected with the mounting block 3 slot, and the bucket tooth body 12 is placed under the mounting block 3, and the limit frame 6 is loosened. The elastic action of the supporting spring piece 5 pushes the limit frame 6 to reset, so that the limit frame 6 slides in the mounting block 3 connected with the slot, and the limit frame 6 with a "U"-shaped cross-section is meshed and connected with the connecting plate 7, which plays a limiting role on the connecting plate 7;

[0028] As attached Figure 1 and attached Figure 4As shown in , the second mounting rod 11 is threadedly connected to the connecting shaft 10, and the second mounting rod 11 rotates inside the connecting block 9 and drives the connecting block 9 to move, so that the connecting block 9 with a square structure in the longitudinal section is connected with the connecting plate 7 by a slot. When it is necessary to adjust the angle of the bucket tooth body 12, the limit frame 6 is pressed inward to disengage the limit frame 6 from the meshing connection with the connecting plate 7, and then the bucket tooth body 12 is rotated, and the bucket tooth body 12 drives the support frame 8 fixed on its outside to rotate, and the connecting plate 7 integrally arranged above the support frame 8 rotates, and the connecting plate 7 drives the connecting block 9 installed inside to rotate, and the connecting block 9 drives the connecting shaft 10 to rotate in the mounting block 3. After adjusting the bucket tooth body 12 to a suitable angle, the limit frame 6 is released, and the elastic action of the supporting spring piece 5 pushes the limit frame 6 to reset, so that the limit frame 6 and the connecting plate 7 are meshed and connected, and the bucket tooth body 12 is fixed;

[0029] As attached Figure 1 As shown in the figure, when the tip of the bucket tooth body 12 is worn and needs to be replaced, the second mounting rod 11 is rotated to disengage it from the threaded connection with the connecting shaft 10. The second mounting rod 11 drives the connecting block 9 to move to disengage it from the slot connection with the connecting plate 7. The bucket tooth body 12 can be removed from the lower end of the mounting block 3 for replacement.
