A screw 7 is connected to the upper end of the screw 7, a handle 8 is connected to the upper end of the screw 7, a wing nut 9 is threaded onto the outer thread of the screw 7, an upper connecting block 10 is rotatably connected to the lower end of the screw 7, an mounting block 11 is connected to the middle of the lower end of the upper connecting block 10, a lower connecting block 12 is connected to the lower end of the mounting block 11, a guide rod 32 is connected to the middle of the lower end of the lower connecting block 12, the lower part of the guide rod 32 passes through the interior of the lower fixing block 6, and a spring 13 is provided on the outside of the guide rod 32 and between the lower connecting block 12 and the lower fixing block 6.

[0023] Both U-shaped seats 4 have through slots 14, and mounting blocks 11 on both sides have mounting holes. A connecting shaft 15 is rotatably connected between the two mounting holes. Both ends of the connecting shaft 15 pass through the slots 14, and flexible scrapers 16 are distributed around the outer circumference of the connecting shaft 15.

[0024] A bushing 17 is fitted around the outside of the connecting shaft 15. A driven pulley 18 is fixedly connected to the outside of the bushing 17. The driven pulley 18 is located inside one of the U-shaped seats 4. A through hole is opened on one side of the outside of the bushing 17. An internal threaded sleeve 19 is welded to the outside of the through hole. A locking bolt 20 is threaded inside the internal threaded sleeve 19. The lower end of the locking bolt 20 passes through the through hole and abuts against the connecting shaft 15 to fix the driven pulley 18. A locking nut 21 is threaded on the outside of the locking bolt 20.

[0025] A motor 22 is installed on one side of the outer wall of the U-shaped base 4. The output end of the motor 22 extends into the interior of the U-shaped base 4 and is connected to a drive pulley 23. The drive pulley 23 and the driven pulley 18 are connected by a transmission belt 24.

[0026] The outer circumference of the connecting shaft 15 is connected with protruding strips 25. The lower end of the flexible scraper 16 is provided with a long groove 26, which is adapted to the protruding strips 25. Both sides of the protruding strips 25 are provided with connecting holes 27. Both sides of the flexible scraper 16 are provided with connecting grooves 28. The flexible scraper 16 is detachably connected to the protruding strips 25 by bolts 29 passing through the connecting grooves 28 and connecting holes 27.

[0027] Both ends of the connecting shaft 15 extend to the outside of the mounting block 11. Both sides of the connecting shaft 15 are connected to the stop block 31 by screws 30, which facilitates limiting the two ends of the connecting shaft 15.

[0028] Working principle:

[0029] Move the cleaning device under the conveyor belt and adjust its height by operating the electric push rod 3. The extension and retraction of the electric push rod 3 drives the U-shaped seat 4 and all its components (including the upper fixed block 5, the lower fixed block 6, the screw 7, etc.) to move up and down, thereby adjusting the relative height between the flexible scraper 16 and the conveyor belt.

[0030] After the electric push rod 3 completes the initial height adjustment, the height of the flexible scraper 16 is further fine-tuned by rotating the handle 8;

[0031] The rotation of the handle 8 drives the screw 7 to rotate. Since the screw 7 is threadedly connected to the upper fixed block 5 and rotatably connected to the upper connecting block 10, the rotation of the screw 7 is converted into the lifting and lowering motion of the upper connecting block 10, thereby adjusting the contact degree between the flexible scraper 16 and the conveyor belt.

[0032] After the relative height and contact degree between the flexible scraper 16 and the conveyor belt are adjusted, the motor 22 is started to rotate and clean. The output end of the motor 22 drives the connecting shaft 15 to rotate through the transmission mechanism (including the driving pulley 23, the transmission belt 24 and the driven pulley 18).

[0033] The rotation of the connecting shaft 15 drives the flexible scraper 16 on it to rotate. The lower end of the flexible scraper 16 contacts and scrapes the surface of the conveyor belt, thereby removing the magnetic powder residue on the surface of the conveyor belt.

[0034] Because the flexible scraper 16 has a certain degree of elasticity and wear resistance, it can adapt to the slight unevenness of the conveyor belt surface and ensure the cleaning effect;

[0035] In addition, wear of the flexible scraper 16 is inevitable during the rotation cleaning process. In order to extend the service life of the flexible scraper 16 and facilitate replacement, this device adopts a detachable design. By passing the bolt 29 through the connecting groove 28 and the connecting hole 27, the flexible scraper 16 and the convex strip 25 can be easily disassembled and installed.
