Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveying device cleaning technology, and more specifically, to a conveying device for coal mine transportation that is easy to clean. Background Technology
[0002] Coal mines are areas where humans extract coal resources in coal-rich areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, tunnels are usually dug underground to extract the coal; this is called an underground coal mine. When the coal seam is very close to the surface, the surface soil is usually stripped away to extract the coal; this is called an open-pit coal mine. Whether it is an underground or open-pit coal mine, the excavated coal needs to be transported before it can be processed in the next step. Therefore, coal conveying equipment is needed to transport and transfer the excavated coal.
[0003] During the transportation of coal in existing belt conveyors, some residues, due to their high viscosity, adhere to the conveyor belt. As a result, after prolonged use, more coal residues tend to remain on the conveyor belt, causing them to clump together and remain on the surface. This not only increases the workload of the belt conveyor itself but also affects the normal transportation efficiency of the coal mine. Cleaning along the conveyor after shutdown is quite cumbersome. Utility Model Content

[0023] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0024] As attached Figure 1 To be continued Figure 3 The present invention provides a coal mine transportation conveying device that is easy to clean, including a belt conveyor 1, a first cleaning device 2, an adjusting device 3 and a second cleaning device 4. The right end of the top of the belt conveyor 1 is fixedly installed with the first cleaning device 2, the adjusting device 3 is installed on the top of the first cleaning device 2, and the second cleaning device 4 is detachably installed on the right side of the belt conveyor 1.
[0025] like Figure 2As shown, the first cleaning device 2 includes a fixed cover 21, a first scraper 27 and a second scraper 29. The top of the fixed cover 21 is provided with a sliding groove 23. Limiting brackets 22 are fixedly installed on both sides of the top of the inner wall of the fixed cover 21. Fixed shafts 24 are fixedly installed on both the left and right sides of the upper end of the fixed cover 21. A first sleeve 25 is movably sleeved on the outer surface of the left fixed shaft 24. A first gear 26 is fixedly sleeved on the left end of the first sleeve 25. There are multiple first scrapers 27 and second scrapers 29. Multiple first scrapers 27 are fixedly installed at the bottom of the first sleeve 25. A second sleeve 28 is rotatably installed on the outer surface of the right fixed shaft 24. Multiple second scrapers 29 are fixedly connected to the bottom of the second sleeve 28. A second gear 210 is fixedly sleeved on the right end of the second sleeve 28.
[0026] Among them, multiple first scrapers 27 and multiple second scrapers 29 are distributed alternately.
[0027] By using a first scraper 27 and a second scraper 29 that are staggered and positioned at the top of the conveyor belt 12, when stubborn residue blocks adhere to the surface of the conveyor belt 12, the first scraper 27 first breaks up the residue blocks on the surface of the conveyor belt 12. As the conveyor belt 12 moves, the broken residue blocks move with the conveyor belt 12, and the second scraper 29 breaks up the remaining residue blocks. Through the staggered distribution of the first scraper 27 and the second scraper 29, the residue blocks are completely broken up, and the stubborn residue blocks are thoroughly cleaned.
[0028] like Figure 3 As shown, the adjusting device 3 includes a sliding block 31, a connecting frame 32 is fixedly connected to the bottom of the sliding block 31, a support rod 33 is fixedly connected to the bottom of the connecting frame 32, a fixing rack 34 is fixedly installed on the left side of one end of the support rod 33 and the right side of the other end, and a pushing cylinder 35 is fixedly installed on one side of the sliding block 31.
[0029] The push cylinder 35 is fixedly installed on the top of the fixed cover 21, the connecting frame 32 is slidably installed inside the sliding groove 23, the support rod 33 and the fixed racks 34 at both ends are in a "Z" shape, the fixed racks 34 at both ends of the support rod 33 mesh with the outer surfaces of the first gear 26 and the second gear 210 respectively, and the support rod 33 is slidably installed inside the limit frame 22.
[0030] By extending the cylinder 35, the sliding block 31 drives the fixed racks 34 at both ends of the support rod 33 to move to the left. The fixed racks 34 mesh with the first gear 26 and the second gear 210, causing the first sleeve 25 to rotate on the outer surface of the fixed shaft 24. The first scraper 27 rotates to the side, and the second sleeve 28 rotates on the outer surface of the fixed shaft 24, causing the second scraper 29 to rotate to the side. This causes the first scraper 27 and the second scraper 29 to rotate and fold, preventing the first scraper 27 and the second scraper 29 from affecting the normal transportation of coal in the mine.
[0031] like Figure 4 - Figure 5 As shown, the belt conveyor 1 includes a frame 11, a transmission belt 12 is provided on the top of the frame 11, a mounting frame 13 is fixedly installed on the right side of the frame 11, a plurality of long grooves 14 are provided inside the mounting frame 13, the mounting frame 13 is located diagonally below one end of the transmission belt 12, and an inclined plate 15 is fixedly installed at the bottom of the right end of the frame 11.
[0032] Using the function of the inclined plate 15, when residue and dust fall onto the surface of the inclined plate 15, they slide off the inclined plate 15 through its inclined surface.
[0033] The second cleaning device 4 includes a fixed frame 41, a cleaning brush 42, and an inclined scraper 43. The cleaning brush 42 is fixedly installed on the left side of the lower end of the fixed frame 41, and the inclined scraper 43 is fixedly installed on the top of the fixed frame 41. Multiple locking blocks 44 are fixedly installed on the right side of the lower end of the fixed frame 41. Locking bolts 45 are installed in the internal threads of the locking blocks 44. The cleaning brush 42 and the inclined scraper 43 are located on the right side of the transmission belt 12. The locking blocks 44 are detachably installed inside the long groove 14 by means of the locking bolts 45.
[0034] Through the function of the long groove 14, on the one hand, the second cleaning device 4 can be detachably installed inside the mounting bracket 13, making it easy to remove the second cleaning device 4 for cleaning. On the other hand, through the function of the long groove 14, the position of the cleaning brush 42 and the inclined scraper 43 on the side of the transmission belt 12 can be adjusted so as to clean the surface of the transmission belt 12.
[0035] The working process of this utility model is as follows:
[0036] In use, when cleaning stubborn residue on the surface of the conveyor belt 12, the control push cylinder 35 retracts, causing the sliding block 31 to drive the fixed racks 34 at both ends of the support rod 33 to move to the right. Through the meshing action of the fixed racks 34 with the first gear 26 and the second gear 210, the first sleeve 25 and the second sleeve 28 rotate on the outer surface of the fixed shaft 24. The first scraper 27 and the second scraper 29 unfold and stay on the top of the conveyor belt 12. As the conveyor belt 12 is driven, it drives the stubborn residue blocks on the surface of the conveyor belt 12 to move. The first scraper 27 first breaks the residue blocks on the surface of the conveyor belt 12, and as the conveyor belt 12 is driven, the broken residue moves with the conveyor belt 12. The second scraper 29 breaks the remaining residue blocks. Through the staggered distribution of the first scraper 27 and the second scraper 29, the residue blocks are completely broken, so as to clean the stubborn residue on the surface of the conveyor belt 12.
[0037] The broken residue is scraped by the inclined scraper 43, causing it to slide off the top of the inclined scraper 43 and fall out. As the conveyor belt 12 is driven, the surface of the conveyor belt 12 is cleaned by the cleaning brush 42, which cleans the dust off the conveyor belt 12. The residue and dust fall onto the top of the inclined plate 15 and slide off the inclined plate 15.
