The mounting shell 4 is fixedly passed through a side wall of the excavator bucket body 1 away from the excavating teeth 3, and the bottom of the mounting shell 4 is an open structure. The positive and negative threaded rod 1 401 and the positive and negative threaded rod 2 402 are both rotatably mounted in the mounting shell 4, the positive and negative threaded rod 1 401 is located outside the excavator bucket body 1, and the positive and negative threaded rod 2 402 is located inside the excavator bucket body 1, the two movable seats 1 403 are both threadedly mounted on the positive and negative threaded rod 1 401 and are symmetrically distributed, and the two outer scrapers 404 are respectively fixed The two outer scrapers 404 are fixedly installed at the bottom of the corresponding movable seat 403, and the two outer scrapers 404 are in sliding contact with the outer wall of the excavator bucket body 1. When the positive and negative screw rods 401 rotate, the two movable seats 403 will move in the direction of moving away from or approaching each other. The two outer scrapers 404 are used in conjunction with each other to scrape off the dirt, sand and gravel and other impurities adhering to the outer wall of the excavator bucket body 1. The two movable seats 405 are both threadedly mounted on the positive and negative screw rods 402 and are symmetrically distributed. The two inner scrapers 406 are fixedly installed at the bottom of the corresponding movable seat 405, and the two inner scrapers 406 are in sliding contact with the inner wall of the excavator bucket body 1. When the positive and negative screw rods 402 rotate, the two movable seats 405 will move in the direction of moving away from or approaching each other.

[0024] In this embodiment, the driving assembly is arranged on the mounting shell 4, and the driving assembly is used to control the synchronous and unidirectional rotation of the forward and reverse screw rods 401 and the forward and reverse screw rods 2 402. The driving assembly includes a motor 407, a driving gear 408, a transmission shaft 409, a transmission gear 410 and a driven gear 411. The motor 407 is fixedly mounted on the front outer wall of the mounting shell 4 and is located outside the excavator bucket body 1. The output shaft end of the motor 407 is fixedly connected to the front end of the forward and reverse screw rods 1 401. The motor 407 is used to drive the forward and reverse screw rods 1 401 to rotate. The driving gear 408 is fixedly mounted in the middle part of the forward and reverse screw rods 1 401. The transmission shaft 409 is rotatably mounted in the mounting shell 4 and is located between the forward and reverse screw rods 1 401 and the forward and reverse screw rods 2 402.

The driving gear 408, the transmission gear 410 and the driven gear 411 are set to the same model and size, which can ensure that the forward and reverse screw rods 401 and the forward and reverse screw rods 402 rotate synchronously in the same direction, thereby ensuring the movement synchronization of the two inner scrapers 406 and the two outer scrapers 404, making the cleaning effect more uniform and consistent.

[0025] In this embodiment, a guide block 412 is fixedly installed on the top of each of the two movable seats 403, and a guide groove 413 is provided on the top inner wall of the mounting shell 4. The two guide blocks 412 are slidably installed in the guide groove 413, which guides the movement direction of the two movable seats 403, preventing them from deflecting or shaking during movement, thereby ensuring the smooth progress of the cleaning process.

[0026] In this embodiment, a guide block 2 414 is fixedly installed on the top of the two movable seats 2 405, and a guide groove 2 415 is provided on the top inner wall of the mounting shell 4. The two guide blocks 2 414 are slidably installed in the guide groove 2 415, which guides the movement direction of the two movable seats 2 405, preventing them from deflecting or shaking during movement, thereby ensuring the smooth progress of the cleaning process.

[0027] In this embodiment, it should be noted that the motor 407 adopts a forward and reversible motor purchased on the market, and the motor 407 is provided with a power supply and a control switch. The motor 407 is electrically connected to the internal power supply of the excavator, and its line connection method and control method are mature technologies in this field, so they are fully disclosed and will not be described in detail in this article.

[0028] Through the above structure, when the excavator bucket with a cleaning mechanism provided by the present application is in use and the excavator bucket body 1 needs to be cleaned, the motor 407 is controlled to rotate forward, and the output shaft of the motor 407 drives the forward and reverse screw rod 1 401 to rotate, and the driving gear 408 fixedly mounted on the middle part of the forward and reverse screw rod 1 401 rotates accordingly, and the driving gear 408 drives the transmission gear 410 to rotate, and the transmission gear 410 drives the driven gear 411 to engage with the forward and reverse screw rod 2 402, thereby causing the forward and reverse screw rod 2 402 to rotate synchronously with the forward and reverse screw rod 1 401 in the same direction;

[0029] As the forward and reverse screw rods 401 rotate, the two movable seats 403 move toward each other, and the outer scraper 404 at the bottom of the movable seat 403 slides into contact with the outer wall of the excavator bucket body 1, thereby scraping and cleaning the outer wall of the excavator bucket body 1, and scraping off impurities such as mud, sand and gravel adhering to the outer wall of the excavator bucket body 1;

[0030] At the same time, as the forward and reverse screw rods 2 rotate, the two movable seats 405 move toward each other, and the inner scraper 406 at the bottom of the movable seat 405 slides in contact with the inner wall of the excavator bucket body 1, scraping and cleaning the inner wall of the excavator bucket body 1, and scraping off impurities such as soil, sand and gravel adhering to the inner wall of the excavator bucket body 1;

[0031] Similarly, by controlling the motor 407 to reverse, the two movable seats 1 403 move away from each other, so that the two outer scrapers 404 move away from each other, and the two movable seats 2 405 move away from each other, so that the two inner scrapers 406 move away from each other, and then by controlling the motor 407 to rotate forward and reverse, the forward and reverse screw rods 1 401 and the forward and reverse screw rods 2 402 can be controlled to rotate synchronously in the same direction, driving the outer scrapers 404 and the inner scrapers 406 to clean the inner and outer surfaces of the excavator bucket body 1 at the same time.
