[0002] A coal mine refers to a place rich in coal resources, generally divided into underground coal mines and surface coal mines. When the coal seam is far from the surface, generally choose to dig underground roadways to mine coal, which is an underground coal mine. When the distance between the coal seam and the surface is very close, generally choose to directly strip the surface soil layer to mine coal, which is a surface coal mine. Coal is the most important solid fuel and a kind of combustible organic rock. According to the degree of coalification, it can be divided into four categories: peat, lignite, bituminous coal and anthracite.

A spring A18 is sleeved on the surface of the limiting rod 16. The number of the rotating rollers 4 is two groups. The output end of the motor A3 is fixedly connected with one end of the rotating roller 4. The output end of the electric telescopic rod 8 is fixedly connected with the side of the connecting block 7. The connecting block 7 is slidably connected with the sliding rod 9. One end of the limiting rod 16 is fixedly installed with a pulling head 19. The limiting rod 16 is slidably connected with the clamping block 13. One end of the spring A18 is fixedly connected with the side of the limiting disc 17. The other end of the spring A18 is fixedly connected with the inner side of the U-shaped plate 15.

[0024] In this embodiment, by starting the electric telescopic rod 8 to drive the connecting block 7 to expand and contract, thereby driving the cleaning roller 14 to move, and then starting the motor A3 to drive the rotating rod 11 to rotate, the rotating rod 11 will drive the clamping sleeve 12 to rotate, thereby driving the cleaning roller 14 to rotate, so as to clean the coal slag attached to the surface of the conveyor belt 5. It is not necessary for the staff to clean the outer wall of the conveyor belt 5 separately, reducing the operation steps of the staff, thus facilitating the conveyor belt 5 to convey and process the coal slag, correspondingly improving the use effect and use efficiency of the conveyor belt 5. At the same time, the cleaning roller 14 can be quickly disassembled. First, grasp the pulling head 19 and pull it, so that the limiting rod 16 slides out of the inside of the clamping block 13.

[0027] The working principle of this embodiment: When in use, first start the motor A 3 to drive the rotating roller 4 to rotate, thereby driving the conveyor belt 5 to convey. At this time, the coal mine inside the feeding bin 2 will fall onto the surface of the conveyor belt 5 for conveyance. When the staff needs to clean the conveyor belt 5, they can start the electric telescopic rod 8 to drive the connecting block 7 to expand and contract, thereby driving the cleaning roller 14 to move. Then start the motor A 3 to drive the rotating rod 11 to rotate. The rotating rod 11 will drive the sleeve 12 to rotate, thereby driving the cleaning roller 14 to rotate, and then the cinder attached to the surface of the conveyor belt 5 can be cleaned. It is not necessary for the staff to clean the outer wall of the conveyor belt 5 alone, reducing the operation steps of the staff, thereby facilitating the conveyor belt 5 to convey and process the cinder, correspondingly improving the use effect and use efficiency of the conveyor belt 5. At the same time, the cleaning roller 14 can be quickly disassembled. First, grasp the pull head 19 and pull it, so that the limit rod 16 slides out of the inside of the clamping block 13. At this time, the clamping block 13 can be slid out of the inside of the sleeve 12 to realize the disassembly of the cleaning roller 14, without using complex tools or manual disassembly for a long time, thereby improving the cleaning efficiency of the staff for the cleaning roller 14. When the coal mine is conveyed through the conveyor belt 5, through the design of the fixing plate 20, the insertion block 21, the insertion hole 22, the spring B 23, the protection plate 24 and the fixing threaded rod 25, the two sides of the conveyor belt 5 can be intercepted and guided, preventing the coal mine from slipping laterally due to inertia or vibration during the conveying process, thereby maintaining the stable transmission of coal on the conveyor belt 5, avoiding unnecessary interruptions and cleaning operations, and improving the coal conveying efficiency and the overall output of the production line.
