[0002] The belt conveyor is one of the important production equipment in coal mine transportation operations. For example, the existing Chinese patent with announcement number CN219362335U discloses a coal mine belt conveyor. By installing a cleaning brush on a liftable adjustment structure, the cleaning force of the cleaning brush on the belt can be flexibly adjusted, which is convenient for cleaning different mineral materials attached to the belt, and the cleaned mineral materials can be collected to avoid waste of resources.

[0003] Although the existing coal mine belt conveyors can clean the belts, the current belt conveyors have a fixed transport capacity.

[0030] Among them, Figures 1 to 8As shown, the side of the bracket 1 is vertically slidably connected with a resettable water storage box 9, a fixing frame 24 is fixedly connected between the axis 19 of the side roller 7 and the plug shaft 21, and a scraper 8 is slidably connected to the fixing frame 24, and the scraper 8 is arranged parallel to the axis of the side roller 7.

The other end of the pull wire 23 in the wire sleeve 22 is fixedly connected to the slider 25, and the pull wire 23 is driven by the movement of the slider 901 to pull the slider 25 to move; both the plug shaft 21 and the fixed frame 24 on the shaft 19 are provided with a slide groove 241, and the slide groove 241 is slidably connected to the slider A resettable slider 28 is connected, and a scraper 8 is movably connected between the two sliders 28. Specifically, a reset spring is arranged between the slider 28 and the slide groove 241 to realize its sliding reset function; a connecting rope 26 is fixedly connected between the slider 1 25 and the slider 28, a wire sleeve 27 is fixedly connected in the fixing frame 24 on the side of the plug shaft 21, and the other end of the wire sleeve 27 is fixedly connected to the fixing frame 24 on the side of the shaft 19.

After the conveyor is started, the belt 10 moves to drive the side roller 7 to rotate. At this time, the scraper 8 can scrape off the water film on the side roller 7, thereby preventing the water film formed on the side roller 7 and the belt 10 from slipping when the belt 10 is running after rain.

[0031] Among them, Figure 2 As shown, a water filter plate 11 is fixedly connected to the opening of the water storage box 9. The water filter plate 11 can prevent foreign matter from entering the water storage box 9. Only rainwater can enter the water storage box 9 through the water filter plate 11 and be stored.

[0032] Among them, Figures 1 to 3 As shown, a water storage box 9 can also be set on the side of the bracket 1, and a scraper 8 is provided between the two vertical rods 4. The water storage box 9 is linked with the scraper 8 on the vertical rod 4, thereby driving the scraper 8 to scrape off the water film on the centering roller 5.

[0033] Among them, Figures 1 to 8 As shown, a resettable scraper 8 is rotatably connected between the two sliders 28. Specifically, a torsion spring can be set between the scraper 8 and the slider 28 to realize its rotation reset function; blocks 30 are provided on both sides of the fixed frame 24, and the blocks 30 are used to limit the rotation angle of the scraper 8; in the initial state, the scraper 8 is deflected to one side block 30 and connected with it. When the slider 28 is pulled and moved, the scraper 8 is driven to connect with the side roller 7 in a deflected state, and the initial deflection direction of the scraper 8 is opposite to the rotation direction of the side roller 7. When the belt 10 drives the side roller 7 to rotate, it drives the scraper 8 to rotate, so that the scraper 8 is deflected to the other side block 30. In this process, the slider 28 will produce a return slide, pulling the pull wire 23 in the wire sleeve 1 22 to move; a movable block 904 is slidably connected to the slider part 901, and a piston part 905 is integrally connected to the side of the movable block 904. A cylinder body part is provided in the slider part 901, and the piston part 905 is slidably connected to In the cylinder body, a connecting hole 902 is provided in the water storage box 9, one end of the connecting hole 902 is connected to the water storage box 9, and the other end is connected to the cylinder body. A connecting hole 903 is also provided on the lower side of the cylinder body, one end of the connecting hole 903 is connected to the cylinder body, and the other side is connected to the outer side of the slider 901; when the scraper 8 is driven by the side roller 7 to deflect, the pull wire 23 in the wire sleeve 22 is pulled, and the end of the pull wire 23 is fixedly connected to the movable block 904, thereby pulling the movable block 904 and the movable block 904 to move. The plug part 905 moves. In the initial state, the piston part 905 blocks the connecting hole 1 902 and the connecting hole 2 903. After the piston part 905 moves, the connecting hole 1 902 and the connecting hole 2 903 are connected through the cylinder body part. At this time, the water accumulated in the water storage box 9 flows out from the connecting hole 1 902 and the connecting hole 2 903 to the outside, and the water storage box 9 gradually resets, thereby resetting the scraper blade 8. The scraper blade 8 is no longer continuously connected to the side roller 7, thereby avoiding the problem of scraper blade 8 being worn.

In the initial state, the limiting portion 311 on the claw 31 is connected to the side of the movable block 904, so that the movable block 904 can limit the counterclockwise rotation of the claw 31 , while the claw 31 is not restricted from rotating clockwise. During the downward movement of the sliding portion, the claw 31 is connected with the tooth 102 and rotates continuously clockwise. The tooth 102 does not restrict the claw 31. During the upward movement of the slider 901, the claw 31 is restricted from rotating counterclockwise, so that the claw 31 is engaged with the tooth 102, restricting the slider 901 from moving upward, that is, the slider 901 can only move downward in one direction at this time; the movable block 904 is provided on the side The block 908 that can be slid and reset is a plastic block that can be plastically deformed. A slot is provided at the corresponding position of the side of the slider part 901. When the scraper 8 is affected by the rotation of the side roller 7 and the direction is deflected, the pull wire 23 applies a pulling force to the movable block 904. At this time, the slider part 901 is restricted from moving, and the block 908 on the movable block 904 is plastically deformed and disengaged from the slot, thereby causing the movable block 904 to move, driving the connecting hole 1 902 to be connected with the connecting hole 2 903. At the same time, the side of the movable block 904 is no longer connected to the limiting part 311 on the claw 31, and the claw 31 can rotate counterclockwise. At this time, the slider part 901 is no longer restricted from moving upward. In the process of water in the water storage box 9 flowing out of the through hole, the weight of the water storage box 9 is reduced, and it moves upward under the action of the reset spring until the movable block 904 is in contact with the upper wall part of the slide groove 101, so that the block 908 shrinks and then re-engages in the slot, and all states are reset.

[0035] Among them, Figures 2 to 4 As shown, a connecting pipe 29 is fixedly connected to the lower end of the second connecting hole 903, and a water outlet 291 at the other end of the connecting pipe 29 is fixedly connected to the fixed frame 24; when the scraper 8 is connected to the side roller 7, not only the water film on the side roller 7 will be scraped off, but also a small amount of overflowed coal ash on it will be scraped off; and during the resetting process of the water storage box 9, the scraper 8 and the side roller 7 are separated through the water outlet 291, and the water flowing out of the water storage box 9 flows out from the water outlet 291 to clean the scraper 8, thereby keeping the scraper 8 clean and maintaining its scraping ability; a drainage groove 17 is fixedly connected to the connecting frame 3, and the drainage groove 17 is used to receive and discharge the sewage dripping from the scraper 8.
