[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] See also Figure 1 - Figure 4Example 1 is described. In the figure, an assembled excavator bucket includes a bucket body 1. A fixing plate 2 is fixedly connected to the edge of the top of the bucket body 1. Bucket ear plates 3 for connecting to the excavator bucket rod are symmetrically welded to the fixing plate 2 and the rear side wall of the bucket body 1. A bucket tooth assembly 4 is connected to the edge of the bottom of the bucket body 1. The bucket tooth assembly 4 includes a tooth plate 401, a tooth root 402, a pin hole 403, a bucket tooth sleeve 404 and a pin shaft 405. The tooth plate 401 is fixedly connected to the tooth root 402 at equal intervals. It is connected to a number of tooth roots 402, and a pin hole 403 is opened through the tooth root 402. A bucket tooth sleeve 404 is provided on the tooth root 402. The bucket tooth sleeve 404 cooperates with the pin hole 403 of the tooth root 402 through a pin shaft 405 to achieve detachable installation. The fixed plate 2 is fixedly connected to the side plates 5 at both ends. A number of mounting holes 6 are opened at equal intervals on the edge of the front side of the side plate 5. The front side of the side plate 5 is detachably connected to the side shovel assembly 7 and the wear-resistant assembly 8 through the mounting holes 6.

[0026] See also Figure 3 and Figure 4 , the fixed plate 2, tooth plate 401 and side plate 5 shown in the figure are all integrally formed with the bucket body 1, and a plurality of grooves 9 are provided on the outer wall of the rear side of the bucket body 1;

[0027] In this embodiment, a bucket tooth assembly 4 is provided on the front side of the bucket body 1. By utilizing the detachable feature of the pin shaft 405, the bucket tooth sleeve 404 of the corresponding shape can be replaced according to actual use needs, and the bucket tooth sleeve 404 that is worn during the use of the bucket body 1 can also be quickly replaced, which greatly reduces the maintenance cost and time. At the same time, the detachable design of the side shovel assembly 7 and the wear-resistant assembly 8 makes it possible to flexibly replace the corresponding components according to different working environments and needs, thereby improving the adaptability and service life of the excavator bucket. Through modular design, not only the adaptability and maintenance convenience of the bucket are improved, but also the maintenance cost and time are reduced, thereby improving working efficiency.

[0028] In actual applications, the side shovel assembly 7 and the wear-resistant assembly 8 of the assembled excavator bucket can be selectively installed according to specific working conditions. For example, when slope excavation or cleaning operations are required, the side shovel assembly 7 can be installed to improve working efficiency; and when the excavation surface needs to be protected or the service life of the bucket needs to be extended, the wear-resistant assembly 8 can be installed.

[0029] It should be noted that the bottom edge of the bucket body 1 can be designed as a replaceable structure so that the bottom edge of different sizes or shapes can be replaced according to different working environments, thereby improving the adaptability and flexibility of the bucket to adapt to more diverse working requirements. The bucket tooth sleeve 404 in the bucket tooth assembly 4 can be made of wear-resistant material, or the surface of the bucket tooth sleeve 404 can be hardened to extend its service life.

[0030] Example 2

[0031] See also Figure 5 and Figure 6 Example 2 is described. This embodiment further illustrates Example 1. In the figure, the side shovel assembly 7 includes a connecting plate 701 and a side shovel tooth 702. The connecting plate 701 is connected to the mounting hole 6 at the front edge of the side plate 5 by bolts, and the side shovel tooth 702 is fixedly connected to the outer edge of the connecting plate 701.

[0032] Furthermore, the wear-resistant assembly 8 includes a wear-resistant frame 801 and a wear-resistant plate 802. The wear-resistant frame 801 is connected to the mounting hole 6 at the front edge of the side plate 5 by bolts, and the wear-resistant plate 802 is fixedly connected to the top of the wear-resistant frame 801.

[0033] In this embodiment, the side scraper assembly 7 and the wear-resistant assembly 8 are bolted together for easy installation and removal, making the excavator bucket more adaptable to different operating environments. For example, during earthwork operations, the side scraper assembly 7 effectively cleans the edges of the excavation surface, improving operational efficiency. Meanwhile, during excavation of hard materials such as ore, the wear-resistant assembly 8 protects the bucket body from excessive wear, extending its service life.

[0034] Specifically, when the connecting plate 701 in the side shovel assembly 7 abuts against the outer wall of the side plate 5, a sealing gasket can be provided to prevent materials from entering the connection part, thereby ensuring the tightness and reliability of the connection. At the same time, the surface of the wear-resistant plate 802 can be specially treated, such as spraying a wear-resistant coating or using a high-hardness material, to further improve the wear resistance.

[0035] Example 3

[0036] See also Figure 1 and Figure 3 Example 3 is described. This embodiment further illustrates Example 2. In the figure, the bucket tooth assembly 4 further includes a reinforcing plate 406 and a slot 407. The reinforcing plate 406 is fixedly connected to the rear side of the top of the tooth plate 401. The bottom of the front side of the reinforcing plate 406 is provided with a slot 407, and the slot 407 is embedded with a tooth root 402.

[0037] Furthermore, a plurality of reinforcing ribs 10 are fixedly connected to the inner wall of the bucket body 1 at equal intervals, and the length direction of the reinforcing ribs 10 is consistent with the length direction of the bucket body 1;

[0038] In this embodiment, the reinforcement plate 406 can be used to improve the structural strength of the front side of the bucket body 1. The design of the slot 407 makes the installation of the tooth root 402 more stable, thereby improving the overall durability and reliability of the bucket. The setting of the reinforcement rib 10 further enhances the rigidity of the bucket body 1, making it less likely to deform when subjected to heavy loads, thereby ensuring the stability and safety of the bucket during long-term use.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
