Description

Technical Field

[0001] The utility model relates to the technical field of excavator accessories, in particular to a bucket tooth for an excavator which is easy to assemble and disassemble. Background Art

[0002] Excavator bucket teeth are important parts of the excavator. Bucket teeth are installed at the front end of the excavator bucket to shovel hard objects such as stones and soil to protect the bucket from damage. Therefore, during use, bucket teeth need to constantly contact with hard objects such as stones, and bucket teeth themselves are easily damaged and need to be replaced.

[0003] In the existing bucket tooth connection of the excavator, the bucket tooth is generally fixed to the tooth seat by a connecting pin and a locking washer. When the damaged bucket tooth needs to be replaced, the pin shaft must be taken out first, and the pin shaft is usually disengaged by hitting with a hammer, and violence is often required during disassembly and assembly. When the bucket tooth located in the middle needs to be replaced, it is difficult to disassemble and assemble due to the small gap between the bucket teeth. For this reason, we propose a bucket tooth for excavators that is easy to disassemble and assemble. Utility Model Content

[0023] When installing the bucket tooth 2, first clamp the bucket tooth 2 on the outside of the tooth seat 1, then insert the insert sleeve 9 between the first through hole 4 and the second through hole 6, and then drive the rotating rod 25 to rotate through the rotating component. When the rotating rod 25 rotates, it will drive the cam 24 to rotate. When the cam 24 rotates, it will squeeze the connecting block 17, so that the upper and lower connecting blocks 17 move relative to each other, and the sliding column 10 will be inserted into the corresponding positioning hole 5, so that the tooth seat 1 and the bucket tooth 2 can be stably connected. When disassembling the bucket tooth 2, it is only necessary to rotate the rotating rod 25 in the opposite direction through the rotating component to disengage the cam 24 from the connecting block 17. At this time, under the action of the first spring 16, the sliding column 10 will disengage from the positioning hole 5, and then the bucket tooth 2 can be removed by taking out the insert sleeve 9, so that the bucket tooth 2 can be easily disassembled.

[0024] The rotating assembly includes a connecting sleeve 23, which is fixedly connected to the left end of the rotating rod 25. The outer surface of the connecting sleeve 23 is provided with a plurality of strip-shaped openings 18. A slider 19 is slidably connected to the strip-shaped opening 18. A transmission block 21 is fixedly connected between the sliders 19. A second spring 22 is connected between the transmission block 21 and the connecting sleeve 23. The left end face of the transmission block 21 is fixedly connected to a driving rod 20. The left end of the driving rod 20 is fixedly connected to a rotating block 12. The outer surface of the rotating block 12 is integrally connected with a clamping block 11. The outer surface of the insert 9 is provided with a clamping socket 15 adapted to the clamping block 11. The clamping block 11 is opened inside the clamping socket 15.

[0025] When installing the bucket tooth 2, pull out the rotating block 12 to the outside. At this time, with the assistance of the driving rod 20, the slider 19 will be driven to slide along the strip mouth 18 to the far left, and the second spring 22 will be stretched. Then, rotate the rotating block 12, and the rotating block 12 will drive the driving rod 20, the connecting sleeve 23 and the rotating rod 25 to rotate, so that the slide column 10 can slide out. Then, release the rotating block 12 and clamp the block 11 in the bayonet 15 to prevent the rotating rod 25 from rotating. When disassembling the bucket tooth 2, use a crowbar to make the block 11 disengage from the bayonet 15, and then rotate the rotating block 12 again, thereby avoiding the need to use a hammer to cooperate with the push rod to knock, which is conducive to the replacement of the bucket tooth 2 in the middle position.

[0026] Two groups of fixing blocks 13 are fixedly connected to the outer surface of the rotating block 12 . The fixing blocks 13 abut against the outer surface of the bucket tooth 2 , and a prying opening is formed on one side of the fixing block 13 close to the bucket tooth 2 .

[0027] The crowbar can be inserted conveniently through the crowbar opening on the fixing block 13 , thereby facilitating the block 11 to be separated from the crowbar opening 15 .

[0028] The front and rear sides of the outer surface of the bucket tooth 2 are both provided with sockets 7 , and the front and rear sides of the outer surface of the tooth seat 1 are both fixedly connected with plug blocks 3 , and the plug blocks 3 are plugged into the corresponding sockets 7 .

[0029] When the bucket tooth 2 is clamped, the insert block 3 will be inserted into the socket 7, which is conducive to the accurate clamping of the bucket tooth 2.

[0030] The front and rear sides of the outer surface of the insert cylinder 9 are fixedly connected with positioning blocks 14 , and the front and rear sides of the left end surface of the bucket tooth 2 are provided with positioning openings 8 , and the positioning blocks 14 are inserted into the positioning openings 8 .

[0031] When installing the insert cylinder 9 , the positioning block 14 will be inserted into the positioning opening 8 , thereby facilitating the subsequent accurate insertion of the sliding column 10 into the positioning hole 5 .

[0032] The bucket teeth 2 and the tooth seat 1 are both made of alloy steel.

[0033] Working principle: When installing the bucket tooth 2, first clamp the bucket tooth 2 on the tooth seat 1, insert the plug block 3 into the socket 7, then insert the insert tube 9 between the first through hole 4 and the second through hole 6, and then pull the rotating block 12 outward. At this time, with the assistance of the driving rod 20, the slider 19 will slide along the strip opening 18 to the leftmost side, the second spring 22 will be stretched, and then the rotating block 12 will be rotated, and the rotating block 12 will drive the driving rod 20, the connecting sleeve 23 and the rotating rod 25 to rotate. When the rotating rod 25 rotates, the cam 24 will be driven to rotate. When the cam 24 rotates, the connecting block 17 will be squeezed, so that the upper and lower connecting blocks 17 move relative to each other, and the sliding column 10 will be inserted into the corresponding positioning hole 5, so that the tooth seat 1 and the bucket tooth 2 can be stably connected. Then, the rotating block 12 is loosened and the clamping block 11 is clamped in the clamping port 15 to prevent the rotating rod 25 from rotating. When installing the insert 9, the positioning block 14 will be inserted into the positioning port 8, so that the subsequent sliding column 10 can be accurately inserted into the positioning hole 5.

[0034] When disassembling the bucket tooth 2, insert the crowbar into the prying hole on the fixed block 13 to disengage the clamping block 11 from the clamping hole 15, and then rotate the rotating block 12 in the opposite direction again to disengage the cam 24 from the connecting block 17. At this time, under the action of the first spring 16, the sliding column 10 will be disengaged from the positioning hole 5, and then the insert tube 9 can be taken out to disassemble the bucket tooth 2, which makes it convenient to disassemble the bucket tooth 2, thereby avoiding the need to use a hammer and a push rod to knock, which is conducive to replacing the bucket tooth 2 in the middle position.
