Description

Technical Field

[0001] This utility model relates to the field of cleaning technology, specifically a coal conveyor belt cleaning device. Background Technology

[0002] During coal transportation, a large amount of coal adheres to the surface of the conveyor belt. This not only increases the weight of the conveyor belt and reduces transportation efficiency, but may also lead to damage to the conveyor belt and increase maintenance costs. In addition, the coal adhering to the conveyor belt may fall off during transportation, causing environmental pollution and resource waste.

[0003] Currently, existing cleaning devices typically use a coal scraper to directly contact the tail end of the conveyor belt to scrape off the coal adhering to the conveyor belt. However, due to the long-term contact between the coal scraper and the conveyor belt, the coal scraper is easily worn, and the contact between the two also generates a lot of noise, resulting in a short service life for the coal scraper. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a coal conveyor belt cleaning device. The contact wheel of the coal conveyor belt cleaning device makes priority contact with the conveyor belt driven by the active roller. At this time, the scraping end of the scraper seat does not contact the conveyor belt, which avoids excessive wear caused by long-term contact between the scraper seat and the conveyor belt. At the same time, it also reduces the noise generated by the friction between the two, and makes the service life of the scraper seat longer.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A coal conveyor belt cleaning device includes a drive roller and a conveyor belt that is driven by the drive roller to transport coal; a frame is installed on one side of the drive roller, a tilting shaft is rotatably installed on the frame, and a coal scraper is detachably installed on the tilting shaft; a drive assembly is also installed on the frame, which can drive the coal scraper to always tilt toward the location of the drive roller.

[0007] The coal scraper is equipped with abutment wheels on both sides of its scraping end. These abutment wheels preferentially contact the conveyor belt driven by the drive roller, so that the scraping end of the coal scraper is not in contact with the conveyor belt.

[0008] Using the above scheme, the contact wheel of the coal conveyor belt cleaning device first contacts the conveyor belt driven by the active roller. At this time, the scraping end of the scraper seat does not contact the conveyor belt, which avoids excessive wear caused by long-term contact between the scraper seat and the conveyor belt. At the same time, it also reduces the noise generated by the friction between the two, making the service life of the scraper seat longer.

[0009] As a preferred embodiment of a coal conveyor belt cleaning device, a flip-up clapper is installed on the side of the coal scraper seat.

[0010] In order to facilitate the cleaning of coal adhering to the coal scraper, the above solution is adopted. A flip-up clapper is installed. Since the coal scraper will generate reciprocating vibration when cleaning coal, it will drive the clapper to move back and forth. By hitting the coal scraper back and forth with the clapper, the coal adhering to the coal scraper can be shaken off quickly.

[0011] As a preferred embodiment of a coal conveyor belt cleaning device, the bottom of the clapper is equipped with multiple linearly arrayed buffer pads located on the coal scraper seat.

[0012] In order to reduce the noise generated by the back-and-forth movement of the clapper, multiple buffer pads are installed at the bottom of the clapper to prevent it from directly contacting the coal scraper seat, thereby reducing the noise generated by the movement of the clapper.

[0013] In a preferred embodiment of a coal conveyor belt cleaning device, the drive assembly includes a positioning frame fixed to the frame, on which a guide rod is fixed;

[0014] A rotating sleeve is concentrically fitted on the rotating shaft. The bottom end of the rotating sleeve is connected to a rotating pusher. The rotating pusher is slidably mounted on the guide rod. A spring is also fitted on the guide rod to push the rotating pusher and drive the coal scraper to rotate towards the location of the drive roller.

[0015] In order to drive the coal scraper to always rotate toward the location of the drive roller, the spring pushes the rotating push seat to rotate the rotating sleeve toward the location of the drive roller. At this time, the coal scraper will rotate toward the location of the drive roller, and the scraping end of the coal scraper will scrape off the coal attached to the conveyor belt.

[0016] As a preferred embodiment of a coal conveyor belt cleaning device, the side of the tilting sleeve is threaded with two mutually perpendicular fastening screws, which can fix the tilting sleeve to the tilting shaft.

[0017] In accordance with the above scheme, a rotating sleeve is fixed with a fastening screw to facilitate the adjustment of the orientation of the coal scraper. When there is a deviation between the scraping end of the coal scraper and the conveyor belt, the orientation of the rotating sleeve can be adjusted by disassembling the fastening screw, thereby changing the orientation of the coal scraper and facilitating the adjustment of the orientation of the coal scraper.

[0018] In a preferred embodiment of a coal conveyor belt cleaning device, the coal scraper seat is limited and installed on the limiting rib fixed to the rotating shaft body, and the coal scraper seat and the limiting rib are connected together by a pin, with a pin inserted at the end of the pin.

[0019] Using the above solution, to facilitate the disassembly of the coal scraper, when the coal scraper needs to be replaced, the pin can be removed and the latch taken out, thus easily completing the replacement of the coal scraper.

[0020] After adopting the above technical solution, the beneficial effects of this utility model are:

[0021] 1. The contact wheel of the coal conveyor belt cleaning device makes priority contact with the conveyor belt driven by the active roller. At this time, the scraping end of the scraper seat does not contact the conveyor belt, which avoids excessive wear caused by long-term contact between the scraper seat and the conveyor belt. It also reduces the noise generated by the friction between the two, making the service life of the scraper seat longer.

[0022] 2. To facilitate the cleaning of coal adhering to the coal scraper, a rotating clapper is installed. Since the coal scraper will generate reciprocating vibration when cleaning coal, it will drive the clapper to move back and forth. By hitting the coal scraper back and forth with the clapper, the coal adhering to the coal scraper can be shaken off quickly.

[0023] 3. In order to reduce the noise generated when the clapper is clapping back and forth, multiple buffer pads are installed at its bottom to prevent the clapper from directly contacting the coal scraper seat, thereby reducing the noise generated by the clapper's movement.

[0024] 4. In order to drive the coal scraper to always rotate toward the location of the drive roller, the spring pushes the rotating push seat to make the rotating sleeve rotate toward the location of the drive roller. At this time, the coal scraper will rotate toward the location of the drive roller, and the coal scraping end of the coal scraper will scrape off the coal attached to the conveyor belt.

[0025] 5. To facilitate the adjustment of the orientation of the coal scraper, a fastening screw is used to fix the rotating sleeve. When there is a deviation between the coal scraping end of the coal scraper and the conveyor belt, the orientation of the rotating sleeve can be adjusted by removing the fastening screw, thereby changing the orientation of the coal scraper and facilitating the adjustment of the orientation of the coal scraper.

[0026] 6. To facilitate the disassembly of the coal scraper, when the coal scraper needs to be replaced, the pin can be removed and the latch taken out, and the replacement of the coal scraper can be easily completed. Attached Figure Description

Detailed Implementation

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] like Figures 1 to 4As shown, a coal conveyor belt cleaning device includes a drive roller 1 and a conveyor belt 2 driven by the drive roller 1 to transport coal. A frame 3 is installed on one side of the drive roller 1, and a tilting shaft 4 is rotatably mounted on the frame 3. A scraper seat 5 is detachably mounted on the tilting shaft 4. A drive assembly is also installed on the frame 3, which can drive the scraper seat 5 to always tilt towards the drive roller 1. Abutment wheels 6 are rotatably mounted on both sides of the scraping end of the scraper seat 5. The abutment wheels 6 preferentially contact the conveyor belt 2 driven by the drive roller 1, so that the scraping end of the scraper seat 5 is just out of contact with the conveyor belt 2. The abutment wheels 6 of this coal conveyor belt 2 cleaning device preferentially contact the conveyor belt 2 driven by the drive roller 1, so that the scraping end of the scraper seat 5 is just out of contact with the conveyor belt 2. This avoids excessive wear caused by long-term contact between the scraper seat 5 and the conveyor belt 2, and also reduces the noise generated by the friction between the two, thus extending the service life of the scraper seat 5.

[0039] like Figures 3 to 4 As shown, a flip-up clapper 7 is installed on the side of the coal scraper 5. The flip-up clapper 7 is installed to facilitate the cleaning of coal adhering to the coal scraper 5. Since the coal scraper 5 will generate reciprocating vibration when cleaning coal, it will drive the clapper 7 to beat back and forth. By hitting the coal scraper 5 back and forth with the clapper 7, the coal adhering to the coal scraper 5 can be shaken off quickly.

[0040] like Figure 5 As shown, multiple buffer pads 8 are linearly arrayed and located on the coal scraper seat 5 at the bottom of the clapper 7. In order to reduce the noise generated when the clapper 7 moves back and forth, multiple buffer pads 8 are installed at its bottom to prevent the clapper 7 from directly contacting the coal scraper seat 5, thereby reducing the noise generated by the clapper 7's movement.

[0041] like Figure 6 As shown, the drive assembly includes a positioning frame 9 fixed to the frame 3, on which a guide rod 10 is fixed; a tilting sleeve 11 is concentrically mounted on the tilting shaft 4, and a tilting pusher 12 is connected to the bottom end of the tilting sleeve 11. The tilting pusher 12 is slidably mounted on the guide rod 10, and a spring 13 is also mounted on the guide rod 10 to push the tilting pusher 12 to drive the coal scraper 5 to always tilt toward the location of the drive roller 1. In order to drive the coal scraper 5 to always tilt toward the location of the drive roller 1, the spring 13 pushes the tilting pusher 12, thereby causing the tilting sleeve 11 to rotate toward the location of the drive roller 1. At this time, the coal scraper 5 will tilt toward the drive roller 1, and the scraping end of the coal scraper 5 will scrape off the coal attached to the conveyor belt 2.

[0042] like Figure 6As shown, two mutually perpendicular fastening screws 14 are threaded onto the side of the tilting sleeve 11, which can be used to fix the tilting sleeve 11 to the tilting shaft 4. The tilting sleeve 11 is fixed with the fastening screws 14 to facilitate adjustment of the orientation of the coal scraper 5. When there is a deviation between the coal scraping end of the coal scraper 5 and the conveyor belt 2, the orientation of the tilting sleeve 11 can be adjusted by removing the fastening screws 14, thereby changing the orientation of the coal scraper 5 and facilitating its adjustment.

[0043] like Figures 7 to 8 As shown, the coal scraper seat 5 is limited and installed on the limiting rib 15 fixed to the shaft of the tilting shaft 4, and the coal scraper seat 5 and the limiting rib 15 are connected together by a pin 16, with a pin 17 inserted at the end of the pin 16. To facilitate the disassembly of the coal scraper seat 5, when the coal scraper seat 5 needs to be replaced, the pin 17 can be removed and the pin 16 can be taken out, and the replacement of the coal scraper can be easily completed.

[0044] The working principle of this utility model:

[0045] In application, the coal scraper seat 5 is installed on the limiting rib 15 of the flipping shaft 4. The spring 13 pushes the flipping push seat 12, thereby causing the flipping sleeve 11 to rotate toward the location of the drive roller 1. At this time, the coal scraper seat 5 will flip toward the location of the drive roller 1, and the coal scraping end of the coal scraper seat 5 will scrape off the coal attached to the conveyor belt 2. The contact wheel 6 on the coal scraper seat 5 will first contact the conveyor belt 2 driven by the drive roller 1. At this time, the coal scraping end of the coal scraper seat 5 will not contact the conveyor belt 2, which avoids excessive wear caused by long-term contact between the coal scraper seat 5 and the conveyor belt 2. At the same time, it also reduces the noise generated by the friction between the two, making the service life of the coal scraper seat 5 longer.

[0046] The coal scraper 5 vibrates back and forth when cleaning coal, which causes the side plate 7 to beat back and forth. The back and forth beating of the side plate 7 can quickly shake off the coal adhering to the coal scraper 5. Multiple buffer pads 8 are installed at the bottom of the side plate 7 to prevent the side plate 7 from directly contacting the coal scraper 5, thereby reducing the noise generated by the beating of the side plate 7.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
