[0002] A mine shaft is a general term for the shafts, chambers, equipment, surface buildings, and structures that form an underground coal mine production system. Sometimes, inclined shafts, vertical shafts, and adits in underground mine development are also referred to as mine shafts. Determining the size of the mining area, the production capacity, and the service life of each mine shaft is one of the key issues that must be resolved in the mine shaft design. Deep excavation of mine shafts requires the use of excavating equipment, and the excavator claw structure is an important part of the excavating equipment.

[0003] Publication number CN215053420U discloses an excavator bucket, including an open bucket body, one end of which is connected to an external mechanical structure for transmission, and bucket teeth are provided on the open side away from the connection end; the bucket body has a bottom plate on the back side of the open side to facilitate contact with the ground and sliding to drag heavy objects; the side of the bucket body is in a near-triangular shape, and the inner angle of the side near the bucket teeth is less than 35 degrees. Although the near-triangular structure of the bucket in this device makes it easier to dig out stones, and when stones are placed on the bucket, there is a large contact area between the bucket and the stones, making the placement and transportation of stones more stable, the digging claws of this device are installed by welding. When the digging claws are damaged, the entire bucket needs to be replaced, which increases the cost of using the digging claws and makes the replacement of the digging claws inconvenient. Therefore, improvements are needed. Utility Model Content

[0025] Please see Figure 2-3The support plate 3 has fixing grooves 9 on both sides of its outer surface, which facilitates the insertion of the fixing block 12. The bucket 1 has storage grooves 10 on both sides of its outer surface, and the fixing block 12 is slidably connected to the inner surface of the storage groove 10. A limiting block 11 is fixedly installed at one end of the inner surface of the storage groove 10. The diameter of the limiting block 11 is larger than the diameter of the fixing block 12. The limiting block 11 can limit the fixing block 12. A spring 13 and a lifting rod 14 are fixedly installed at one end of the outer surface of the fixing block 12. The lifting rod 14 facilitates the replacement of the digging claw, reduces the cost of using the digging claw, and reduces the workload of the workers.

[0026] Example 2

[0027] Please see Figure 2-4 A slot 15 is provided on one side of the outer surface of the fixing plate 2. A locking block 16 is slidably connected to the inner side of the slot 15. An anti-detachment block 17 is fixedly installed on one end of the outer surface of the locking block 16. Mounting holes 18 are provided on the outer surfaces of both the fixing plate 2 and the locking block 16. The threaded rod 19 is conveniently inserted through the mounting holes 18.

Next, the fixed block 12 drives the spring 13 to compress, and then the support plate 3 can be removed from the slide groove 7 and the insertion hole 8 and replaced. Then, the slider 5 and the insertion rod 6 on the replaced support plate 3 are aligned with the slide groove 7 and the insertion hole 8 respectively and inserted. Then, the lifting rod 14 is released, and the spring 13 returns to its original position, driving the fixed block 12 to move. Insert the plate into the inner side of the fixing groove 9 to fix the position of the support plate 3, which facilitates the replacement of the digging claw body 4 and reduces the usage cost of the digging claw body 4. When installing the bucket 1, the fixing plate 2 needs to be installed on the excavator. Then, the anti-detachment block 17 drives the locking block 16 to be aligned with the locking groove 15 and inserted. Then, the rotating block 20 drives the threaded rod 19 to be rotated into the inner side of the mounting hole 18, thereby fixing the position of the locking block 16. The anti-detachment block 17 can prevent the connecting shaft on the bucket 1 from falling off, which improves the stability of the digging claw structure and facilitates the use of the digging claw body 4.
