[0023] A tooth seat wear-resistant device includes a tooth seat 1 and a bucket tooth 2. The middle part of the right side of the tooth seat 1 is fixedly connected with a connecting block 3. The bucket tooth 2 is clamped on the outside of the connecting block 3. The right side of the connecting block 3 and the upper and lower ends of the right side of the tooth seat 1 are provided with a buffer assembly 4. The upper and lower sides of the connecting block 3 are provided with a disassembly assembly 6. The buffer assembly 4 includes a fixed rod 401 arranged on the right side of the connecting block 3. The left end of the fixed rod 401 is fixedly connected to the middle part of the right side of the connecting block 3. The right end of the surface of the fixed rod 401 is provided with a movable sleeve 402. The inner wall of the sleeve 402 is slidably connected to the surface of the fixed rod 401, and the right end of the movable sleeve 402 is fixedly connected to the mounting plate 409. The left ends of the upper and lower sides of the movable sleeve 402 are fixedly connected to the support rods 403. The middle parts of the two support rods 403 are rotatably connected to the connecting rods 404. The ends of the two connecting rods 404 away from the support rods 403 are fixedly connected to the dampers 405. The upper and lower ends of the right side of the gear seat 1 are provided with buffer grooves 406, and the inner cavities of the two buffer grooves 406 are provided with buffer springs 407.

[0024] like Figure 2 、 Figure 3 As shown, one end of the two support rods 403 away from the movable sleeve 402 is rotatably connected to the upper and lower ends of the left side of the mounting plate 409, and one end of the two dampers 405 away from the connecting rod 404 is fixedly connected to the upper and lower ends of the right side of the connecting block 3, respectively. The left ends of the two buffer springs 407 are fixedly connected to the inner walls of the two buffer grooves 406, respectively. The right ends of the two buffer springs 407 are fixedly connected to the movable rod 408, and the other ends of the two movable rods 408 extend to the outside of the two buffer grooves 406, respectively.

[0025] like Figure 1 、 Figure 2 As shown, a through hole 5 is provided in the middle of the bucket tooth 2, and screws 7 are threadedly connected at the upper and lower ends of the through hole 5. The opposite ends of the two screws 7 extend to the outside of the through hole 5. Two sets of disassembly and assembly components 6 include slots 601 provided on the upper and lower sides of the connecting block 3. The two slots 601 are penetrated by a fixing block 602 on the side away from each other. The opposite ends of the two fixing blocks 602 extend to the inside of the through hole 5. A slide bar groove 605 is provided in the middle of the opposite side of the two fixing blocks 602. A slide bar 603 is fixedly connected to the middle of the opposite side of the two slots 601. The other ends of the two slide bars 603 extend to the inside of the two slide bar grooves 605 respectively. The surfaces of the two slide bars 603 are respectively sleeved with springs 604. One end of the two springs 604 is respectively fixedly connected to the inside of the two slots 601, and the other ends of the two springs 604 are respectively fixedly connected to the surfaces of the two fixing blocks 602.

[0026] The working process of the utility model is as follows: when in use, the bucket tooth 2 is sleeved on the outside of the connecting block 3, the bucket tooth 2 is moved to the left, the bucket tooth 2 contacts the inclined side of the fixing block 602, the fixing block 602 is squeezed to move to the inside of the slot 601, the slide bar 603 is squeezed, and it continues to move to the left. The fixing block 602 rebounds to the inside of the through hole 5 under the elastic force of the spring 604, completing the fixation of the bucket tooth 2. The left side of the bucket tooth 2 contacts the right ends of the two movable rods 408, and the inner wall contacts the right side of the mounting plate 409. When the bucket tooth 2 contacts and collides with a hard object, the bucket tooth 2 moves closer to the tooth seat 1. , and moves in the direction of the bucket tooth 2, squeezing the mounting plate 409 to push the movable sleeve 402 to move to the left. The two support rods 403 rotate and use the connecting rod 404 to squeeze the damper 405. At the same time, the left side of the bucket tooth 2 squeezes the two movable rods 408 to move inside the buffer groove 406 to squeeze the buffer spring 407. The buffer spring 407 and the damper 405 buffer the force to prevent the bucket tooth 2 from hitting the tooth seat 1 and causing damage to the tooth seat 1. The bucket tooth 2 is severely worn after long-term use and can be replaced by disassembling and assembling the assembly 6. By removing the screw 7, using a long rod to insert into the through hole 5, the fixing block 602 can be pushed out.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
