Example

[0028] Please see Figure 1-6 This utility model provides a technical solution: a cleaning device for the working surface of the return belt of a belt conveyor, including a cleaning component 1. A belt conveyor body 3 is provided on one side of the cleaning component 1, and a belt body 2 is connected to the outside of the belt conveyor body 3. The belt conveyor body 3 uses a drive device to drive the conveyor belt to move, transporting materials from the feed end to the discharge end. The belt conveyor body 3 is mainly composed of a conveyor belt, a drive device, rollers, idler rollers, a frame, and a tensioning device (not shown in the figure). Since the internal structure and operating principle of the belt conveyor body 3 are existing technologies, they will not be described in detail here. The cleaning component 1 is used to clean the bottom working surface of the belt body 2; a disassembly component 5 is provided on one side of the cleaning component 1.

[0029] The cleaning component 1 includes a support frame 13. Two screws 19 are inserted into one side of the support frame 13. The screws 19 pass through the support frame 13. The top of the connecting frame 15 is limited by a limiting post 14 to prevent excessive displacement. The limiting post 14 is fixed to the top of the screws 19. The connecting frame 15 is sleeved on the outside of the screws 19 and can slide along the axial direction of the screws 19. The bottom of the connecting frame 15 is connected to a scraper 11 and a pressure plate 12, which directly contact the working surface of the belt body 2. The scraper 11 is slidably connected to one side of the belt body 2 and the pressure plate 12 is connected to one side of the scraper 11. The scraper 11 is made of polyurethane. Under the pressure of the first spring 16, the scraper 11 continuously adheres to the working surface of the belt body 2 to scrape off the attached substances and achieve the cleaning function.

[0030] A first spring 16 is sleeved on the outside of the screw 19. A nut 17 and a slotted nut 110 are threaded onto the outside of the screw 19. A hole is opened on one side of the screw 19. A cotter pin 18 connected to one side of the slotted nut 110 is inserted into the inside of the hole. The cotter pin 18 is inserted into the hole of the screw 19 to prevent the nut from loosening and to ensure pressure stability. A support leg 4 is fixed at the bottom of the belt conveyor body 3. The two ends of the support frame 13 are fixed to the inside of the support leg 4. The support frame 13 is fixed to the inside of the belt conveyor support leg 4 and serves as the main support for the cleaning assembly 1. The limiting post 14 is used to limit the travel of the connecting frame 15 on the screw 19.

[0031] The two ends of the first spring 16 are respectively connected to one side of the support frame 13 and the connecting frame 15. The nut 17 and the slotted nut 110 are located at the bottom of the support frame 13. Rotating the nut 17 and the slotted nut 110 can compress or release the first spring 16, adjust the pressure of the scraper 11 on the belt body 2, and ensure that the scraper 11 is in close contact with the surface of the belt body 2 to remove residue. At the same time, adjusting the nut 17 and the slotted nut 110 can prevent the scraper 11 from tilting due to unilateral adjustment.

[0032] The disassembly assembly 5 includes a fixing frame 51. The fixing frame 51 has a limiting groove 54 and a sliding groove 57 respectively. A connecting plate 59 fixed to one side of the pressure plate 12 is inserted into the limiting groove 54. The second spring 52 pushes the sliding plate 53 to insert the locking rod 56 into the locking groove 55 to fix the scraper 11. Several locking grooves 55 are opened on one side of the connecting plate 59. The outer side of the connecting plate 59 is inserted into one side of the scraper 11 and the connecting frame 15 in sequence. One side of the fixing frame 51 is fixed to one side of the connecting frame 15. When the pull rod 58 is pulled, the sliding plate 53 compresses the second spring 52, the locking rod 56 disengages from the locking groove 55, and the connecting plate 59 can be pulled out to disassemble the scraper 11.

[0033] A slide plate 53 is slidably connected to the inner side of the slide groove 57. A pull rod 58 is fixed to the top of the slide plate 53 and extends through the top of the fixing frame 51. A locking rod 56 is fixed to the bottom of the slide plate 53. When the locking rod 56 is inserted into the inner side of the locking groove 55, the scraper 11 is in a fixed state. When the locking rod 56 is removed from the inner side of the locking groove 55, the scraper 11 is in a disassembled state. When replacing the scraper 11, simply pull the pull rod 58, remove the old scraper 11, insert the new component, release the pull rod 58, and the locking rod 56 will snap into the locking groove 55 to complete the fixation, greatly shortening the maintenance time. A second spring 52 is connected between the slide plate 53 and the slide groove 57. A cover plate 6 located on the side of the second spring 52 is connected to one side of the fixing frame 51 by bolts. When the second spring 52 needs maintenance, simply remove the bolts on the side of the cover plate 6 and then remove the second spring 52.

[0034] Working principle: When the belt conveyor body 3 is running, the material and impurities on the return working surface of the belt body 2 will be scraped off by the scraper 11. During the cleaning process, the scraper 11 is subjected to the friction force of the belt body 2. Due to the presence of the first spring 16, the scraper 11 can maintain close contact with the belt body 2 while avoiding excessive wear. The two ends of the first spring 16 are respectively connected to one side of the support frame 13 and the connecting frame 15, providing elastic support for the scraper 11 and ensuring the cleaning effect; the nut 17 and the slotted nut 110 are located at the bottom of the support frame 13. The rotating nut 17 can adjust the position of the connecting bracket 15 on the screw 19, thereby adjusting the gap between the scraper 11 and the belt body 2; and the cotter pin 18 is inserted into the insertion hole on one side of the screw 19 and connected to the slotted nut 110 to prevent the nut from loosening, ensuring the stability of the cleaning assembly 1, removing residual material from the surface of the belt body 2, keeping the belt body 2 clean, and giving the belt body 2 sufficient friction to prevent the belt body 2 from slipping and running off-center. In addition, the top of the scraper 11 contacts the belt body 2 to reduce the phenomenon of belt body 2 shaking.

[0035] When the scraper 11 needs to be disassembled for cleaning or replacement, pull the lever 58 to make the slide plate 53 slide in the slide groove 57. The slide plate 53 slides and drives the locking rod 56 away from the inside of the locking groove 55. At this time, the connecting plate 59 is in a detachable state. After removing the connecting plate 59, the scraper 11 can be cleaned or replaced. After cleaning or replacing the scraper 11, insert the connecting plate 59 back into the limiting groove 54 and release the lever 58. Under the action of the second spring 52, the slide plate 53 returns to its original position, and the locking rod 56 is reinserted into the inside of the locking groove 55, fixing the connecting plate 59 on the fixing frame 51. At this time, the scraper 11 is in a fixed state again, and the cleaning work can continue.

[0036] In summary, by rotating the nut to adjust the position of the connecting frame 15 on the screw 19, the gap between the scraper 11 and the belt body 2 can be adjusted. The scraper 11 can scrape off the material and impurities on the return working surface of the belt body 2, effectively removing residual material from the surface of the belt body 2, keeping the belt body 2 clean, and ensuring the normal operation of the belt conveyor body 3 to adapt to different working conditions and the condition of the belt body 2. While ensuring the cleaning effect, it reduces unnecessary pressure on the belt body 2. The first spring 16 provides elastic support for the scraper 11, so that the scraper 11 can make close contact with the belt body 2 to ensure the cleaning effect, while avoiding excessive wear of the scraper 11 and the belt body 2 due to excessive friction, extending the service life of the equipment and reducing maintenance costs.

[0037] Pulling the lever 58 allows the slide plate 53 to slide, causing the locking lever 56 to leave the locking groove 55, making the connecting plate 59 detachable. After cleaning or replacing the scraper 11, simply reinsert the connecting plate 59 into the limiting groove 54 and release the lever 58. Under the action of the second spring 52, the slide plate 53 returns to its original position, and the locking lever 56 is reinserted into the locking groove 55, thus completing the installation and restoring the fixed state of the scraper 11. The cleaning work can then continue, greatly shortening the time for disassembling and installing the scraper 11, improving maintenance efficiency, and reducing downtime caused by scraper 11 problems.
