Description

Technical Field

[0001] This invention relates to an integrated locking tooth bucket and a bucket and electric shovel having the same, belonging to the field of mining equipment. Background Technology

[0002] Large electric shovel buckets are mainly used for excavating overburden, sand, gravel, and various blasted rocks and minerals from the surface of open-pit mines. The bucket teeth are located at the very front of the bucket. During the excavation process, they are primarily used to directly contact and break up the overburden, sand, gravel, and various blasted rocks and minerals on the excavation face. Because the bucket teeth directly bear the friction and impact forces generated during excavation, they experience significant wear. Therefore, the tooth base and tooth tip usually need to be disassembled and replaced on-site.

[0003] Currently, the bucket teeth of large electric shovels are mainly connected by separate locking pins, which usually require special tools for disassembly and assembly. This is not only cumbersome and inefficient, but the locking pins are also prone to falling off during the disassembly and assembly process. Therefore, it is particularly important to adopt integrated locking teeth to simplify the operation process. Summary of the Invention

[0004] This invention provides an integrated locking tooth bucket tooth, and further provides a bucket and electric shovel having the same. The integrated locking tooth bucket tooth is designed with a first locking member connected to the tooth seat by a pin, and a second locking member connected to the tooth tip by a locking post. During the connection and locking process between the tooth seat assembly and the tooth root, and between the tooth tip assembly and the tooth seat, double springs are used for compression. The entire structure is ingenious and the connection is reliable. During on-site disassembly and assembly, only a hex wrench and a hook are needed to complete the on-site disassembly and assembly work. It can effectively solve the problems of cumbersome operation, low efficiency and easy loss of locking pin caused by the defects of the prior art.

[0056] Furthermore, such as Figure 15 As shown, it also includes a square sheath 5, which includes a first sheath body 5-1, a first tear-off piece 5-2, and a buckle 5-3. The square sheath 5 is made of wear-resistant rubber. The first sheath body 5-1 of the square sheath 5 is installed at the top of the lock body cavity 7-6 of the gear seat 7. The first tear-off piece 5-2 of the square sheath 5 is installed at the first tear opening 7-7 of the gear seat 7. The buckle 5-3 of the square sheath 5 is locked in the slot 7-5 of the gear seat 7 to protect the first lock piece 8.

[0057] When disassembling the gear assembly 3, first use a hook to hook the first lifting lug 7-8 of the gear 7 to prevent the gear assembly 3 from falling during disassembly. Then, take the tearing blade 5-2 from the first tearing opening 7-7 of the gear 7 and forcefully tear the square protective sleeve 5, causing the buckle 5-3 to disengage from the slot 7-5 of the gear 7, thereby tearing off the lower protective sleeve 5. Insert a hex wrench into the second hexagonal hole 13-4 and rotate the square lock cylinder 13 counterclockwise. The second cylinder 15-1 of the lock pin 15 overcomes the pressure of the compression spring 14 and slides towards the bottom of the third cylindrical hole 13-3 of the square lock cylinder 13. The ball head 15-2 of the lock pin 15 slides from the first ball head pit 11-8 of the lock body 11 to the first annular groove 11-7, thereby allowing the square lock cylinder 13 to rotate counterclockwise along the first annular groove 11-7. The gear 13-2 of the square lock cylinder 13... By driving the rack 12-2, the latch 12 slides to the left in the first rectangular cavity 11-5 of the lock body 11, causing the first rectangular block 12-1 of the latch 12 to leave the longitudinal stop block 7-11 of the tooth seat 7. Under the action of torsional force, the upper torsion arm of the torsion spring 9 drives the upper baffle 11-9 of the lock body 11, causing the lock body 11 to rotate upward around the pin 10, causing the block 11-3 of the lock body 11 to leave the stop slot 7-2 of the tooth seat 7. The hook is pushed along the length direction of the bucket tooth, and the tooth seat assembly 3 moves along the length direction of the bucket tooth through the first lifting lug 7-8. The tooth root head 2-2 and the transverse stop block 2-3 of the tooth root 2 exit from the tooth seat cavity 7-1 and the stop slot 7-2 of the tooth seat 7, respectively, thereby completing the disassembly of the tooth seat assembly 3, so that the tooth root 2 and the tooth seat assembly 3 have a second state of separation.

[0058] When installing the tooth seat assembly 3, first hook the first lifting lug 7-8 of the tooth seat 7 with a hook, and lift the tooth seat assembly 3 to the front of the tooth root head 2-2 of the tooth root 2.
