The bucket is provided with multiple screws and guide columns. The bottom of the scraper is threadedly connected to the screw. The scraper sleeve slides on the guide column. A nozzle is fixed on one side of the bucket, and the nozzle faces the inside of the bucket. When the soil adheres to the inside of the bucket, it only takes a short pause to drive the screw to drive the scraper from one end of the bucket to the other end, so as to scrape the soil inside the bucket from the inside of the bucket to the end, and then spray high-pressure water through the nozzle, so as to wash away all the soil, greatly improving the efficiency of bucket cleaning, saving manpower and material resources, and ensuring the construction progress.

[0003] The above technical solution is fixedly connected to the fixing seat by bolts through the nozzle, and then the nozzle sprays high-pressure water to flush the accumulated soil, so as to complete the cleaning of the bucket. The driving sprocket is fixedly connected to the motor drive shaft, and then the motor is hidden inside the bucket. The motor drive shaft of the motor drives the lead screw to rotate through the second chain, so that the scraper can slide in the bucket. However, the above technical solution still has certain defects.

[0043] See also Figure 1-3 , the utility model provides a technical solution: an excavator bucket with automatic cleaning of attached soil, comprising a bucket 1;

[0044] The bucket 1 is provided with a limit device to achieve quick disassembly and installation;

[0045] The limiting device includes a fixed seat 10, a bucket tooth 6 and two protective covers 7. The two protective covers 7 are fixedly connected to the outer walls of the fixed seat 10 on both sides. A bucket tooth groove 14 is provided on the front outer wall of the fixed seat 10. The outer wall of the rear end of the bucket tooth 6 is slidably connected to the inside of the bucket tooth groove 14. The inside of the bucket tooth groove 14 is connected to the inside of the grooves opened on both sides of the fixed seat 10. The outer walls of the two protective covers 7 are provided with push plate grooves 8. The insides of the two push plate grooves 8 are slidably connected with push plates 9. A limit block groove 13 is provided on the outer wall of the rear end of the bucket tooth 6. The inside of the limit block groove 13 is slidably connected to two limit blocks 12. The two limit blocks 12 are away from each other. One end of the bucket tooth 6 is in contact with the inner wall of the groove opened on both sides of the fixed seat 10, and the ends of the fixing rods on the two push plates 9 close to the fixed seat 10 slide through the protective cover 7 and extend to the inside of the grooves opened on both sides of the fixed seat 10 and contact the outer wall of one end of the corresponding limit block 12. The outer walls of the fixing rods on the two push plates 9 are sleeved with second return springs 15, and the two ends of the two second return springs 15 are fixedly connected to the outer wall of the fixing rods on the push plates 9 and the inner wall of the push plate groove 8, respectively. The upper surface of the fixed seat 10 is fixedly connected to the lower surface of the bucket 1. There are four limit devices in total, and the four limit devices are all on the lower surface of the bucket 1.

[0046] Among them, a protective box 2 is fixedly connected to the outer wall of one side of the bucket 1, and an electric motor 16 is installed inside the protective box 2. A two-way threaded rod 17 is rotatably connected to the interior of the upper end of the bucket 1. The output end of the motor 16 rotates and extends to the interior of the bucket 1 and is fixedly connected to one end of the two-way threaded rod 17. Scraper grooves 18 are opened on both sides of the interior of the bucket 1. Scrapers 5 are slidably connected to the inner walls of the two scraper grooves 18. The two scrapers 5 are threadedly connected to the outer wall of the two-way threaded rod 17. A fixed rod 4 is fixedly connected to the interior of the lower end of the bucket 1.

[0047] Furthermore, when the device is used, it is started by connecting an external power supply. First, when it is necessary to clean the soil inside the bucket 1, the output end of the motor 16 rotates to drive the bidirectional threaded rod 17 to rotate while driving the scraper 5 to move in the opposite direction. Then, the scraper 5 moves in the opposite direction to scrape off the soil inside the bucket 1. Then, the water head 3 is connected to the external device and the water head 3 is used to flush the inside of the bucket 1.

[0048] Furthermore, when the bucket tooth 6 needs to be removed, the push plate 9 is pushed to move in the opposite direction to drive the second return spring 15 to contract and drive the limit block 12 to move in the opposite direction, and then the limit block 12 moves in the opposite direction to drive the first return spring 11 to contract and make its other end disengage from the inside of the groove opened on both sides of the fixed seat 10, and then the bucket tooth 6 can be removed from the fixed seat 10.

[0049] The push plate 9 is pushed in the limit device to move in the opposite direction, driving the second return spring 15 to contract and driving the limit block 12 to move in the opposite direction, and then the limit block 12 moves in the opposite direction to drive the first return spring 11 to contract and make its other end disengage from the grooves opened on both sides of the fixing seat 10, and then the bucket tooth 6 can be removed from the fixing seat 10, which is convenient for disassembling the bucket tooth 6 and avoids the need for the staff to use tools to disassemble it, effectively reducing the workload of the staff and improving the maintenance and inspection efficiency of the bucket tooth 6, and driving the two-way threaded rod 17 to rotate by the output end of the motor 16 while driving the scraper 5 to move in the opposite direction, and then the scraper 5 moves in the opposite direction to scrape off the internal soil of the bucket 1, and then the water spray head 3 is connected to the external equipment and the water spray head 3 is used to rinse the inside of the bucket 1, which is convenient for cleaning the soil attached to the inside of the bucket 1, effectively improving the practicability and effectiveness of the equipment and facilitating the staff.

[0050] Working principle: First, when it is necessary to clean the soil inside the bucket 1, the output end of the motor 16 is rotated to drive the bidirectional threaded rod 17 to rotate while driving the scraper 5 to move in the opposite direction, and then the scraper 5 moves in the opposite direction to scrape off the soil inside the bucket 1, and then the water head 3 is connected to the external device and the inside of the bucket 1 is flushed with the water head 3, and then when the bucket tooth 6 needs to be removed, the push plate 9 is pushed to move in the opposite direction to drive the second return spring 15 to contract while driving the limit block 12 to move in the opposite direction, and then the limit block 12 moves in the opposite direction to drive the first return spring 11 to contract while causing its other end to be out of contact with the inside of the groove opened on both sides of the fixed seat 10, and then the bucket tooth 6 can be removed from the fixed seat 10.

[0051] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
