[0028] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0029] The present utility model provides asFigures 1 to 8 A scraper connection structure of a sludge scraper shown in the figure, comprising:

[0030] A central drive shaft 1, a connecting cross bar 2 is arranged on one side of the outer end of the central drive shaft 1, a mounting plate 3 is arranged at the bottom of the connecting cross bar 2, and a sludge scraping plate 4 is fixedly arranged at the bottom end of the mounting plate 3;

[0031] Two first connection grooves 5 are respectively opened on one side and the bottom end of the outer end of the central drive shaft 1. One end of each of the connecting cross bar 2 and the mounting plate 3 is fixedly provided with a first connection block 6. The two first connection blocks 6 are respectively arranged inside the two first connection grooves 5, and a first limiting component is arranged on the first connection block 6;

[0032] A second connection groove 7 is opened at the bottom of the other end of the connecting cross bar 2. A second connection block 8 is fixedly arranged at the top of the other end of the mounting plate 3. The second connection block 8 is arranged inside the second connection groove 7, and a second limiting component is arranged on the second connection block 8.

[0033] The first limiting component includes a first limiting rod 9 arranged at the front end of the central drive shaft 1. A first limiting groove 10 is opened on the first connection block 6. One end of the first limiting rod 9 passes through the outer end of the central drive shaft 1 and extends into the first limiting groove 10. A pull block 11 is fixedly arranged at the other end of the first limiting rod 9. A spring 12 is sleeved on the outer end of the first limiting rod 9. The two ends of the spring 12 are respectively fixedly connected with the outer end of the central drive shaft 1 and the inner side of the pull block 11.

[0034] The second limiting component includes a movable groove 13 opened on the inner wall of the second connection groove 7. A second limiting rod 14 is arranged inside the movable groove 13. A second limiting groove 15 is opened on the second connection block 8. One end of the second limiting rod 14 extends into the second limiting groove 15. A threaded groove 16 is opened on the second limiting rod 14. A first threaded rod 17 is arranged inside the movable groove 13. One end of the first threaded rod 17 extends into the threaded groove 16 and is threadedly connected with the threaded groove 16. The other end of the first threaded rod 17 passes through the other end of the connecting cross bar 2 and is rotatably connected with the other end of the connecting cross bar 2. A rotating block 18 is fixedly arranged at the other end of the first threaded rod 17.

[0035] A plurality of reinforcing rods 19 are fixedly arranged at the bottom end of the connecting cross bar 2. A plug-in block 20 is fixedly arranged at the bottom end of the reinforcing rods 19. A plurality of plug-in grooves 21 are opened at the top end of the mounting plate 3. The plurality of plug-in blocks 20 are respectively arranged inside the plurality of plug-in grooves 21.

[0036] Two limit rings 22 are sleeved on the outer end of the central drive shaft 1. The two limit rings 22 are arranged between one end of the connecting cross bar 2 and the mounting plate 3. Third limit grooves 23 are formed at the opposite ends of the two limit rings 22. The pulling block 11 and the first limit rod 9 are arranged inside the third limit grooves 23. A second threaded rod 24 is fixedly arranged at each of the opposite ends of the two limit rings 22. The second threaded rods 24 are arranged on the side of the central drive shaft 1 away from the connecting cross bar 2 and the mounting plate 3. A threaded sleeve 25 is arranged between the two second threaded rods 24. One end of each of the two second threaded rods 24 extends into the threaded sleeve 25 from both ends of the threaded sleeve 25 and is in threaded connection with the threaded sleeve 25. A guide bar 26 is fixedly arranged on the outer end of the central drive shaft 1 on the side away from the connecting cross bar 2 and the mounting plate 3. The guide bar 26 is arranged inside the second threaded rods 24 and the threaded sleeve 25. Guide grooves 27 are formed at the inner ends of the limit rings 22. Both ends of the guide bar 26 pass through the inside of the two guide grooves 27 respectively.

[0037] Rotate the rotating block 18. The rotating block 18 drives the first threaded rod 17 to rotate. Since the first threaded rod 17 is in threaded connection with the threaded groove 16, the second limit rod 14 disengages from the inside of the second limit groove 15 as the first threaded rod 17 rotates. In this way, the second limit rod 14 releases the limit fixation on the second connection block 8.

[0038] Rotate the threaded sleeve 25. Since the threaded sleeve 25 is in threaded connection with the second threaded rods 24, the two second threaded rods 24 enter the threaded sleeve 25 as the threaded sleeve 25 rotates. The two second threaded rods 24 drive the two limit rings 22 to approach each other. In this way, the first limit assembly leaks out from the inside of the third limit groove 23, pulling the bottom pulling block 11 outward. The pulling block 11 drives the first limit rod 9 to move outward and stretch the spring 12. When one end of the first limit rod 9 leaves the inside of the first limit groove 10, the first connection block 6 on the mounting plate 3 is released from the limit at this time. In this way, the mounting plate 3 and the mud scraping plate 4 can be removed and replaced from the bottom end of the connecting cross bar 2. Pull the top pulling block 11 outward. The pulling block 11 drives the first limit rod 9 to move outward. In this way, the limit on the first connection block 6 on the connecting cross bar 2 can be released, and then the connecting cross bar 2 can be removed from the central drive shaft 1.

[0039] The utility model fixes the connecting cross bar 2 and the first connecting block 6 at one end of the mounting plate 3 on the central transmission shaft 1 through the first limiting component, and then fixes the second connecting block 8 on the mounting plate 3 at the outer end of the connecting cross bar 2 through the second limiting component. In this way, the disassembly process of the mounting plate 3 and the mud scraping plate 4 will be relatively simple and convenient, facilitating the disassembly and replacement of the mounting plate 3 and the mud scraping plate 4, and avoiding the damage to the central transmission shaft 1 during replacement. This embodiment specifically solves the problem existing in the prior art that when the mud scraping plate of the mud scraper is connected to the central transmission shaft, most of them are directly welded to the outer end of the central transmission shaft. In this way, when the mud scraping plate is worn or damaged, it needs to disassemble the central transmission shaft together during replacement, making the replacement process relatively troublesome and possibly damaging the central transmission shaft during the replacement process.

[0040] Only some exemplary embodiments of the present utility model are described by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
