Description

Technical Field

[0001] This utility model belongs to the technical field of mining machinery and equipment, and in particular relates to a scraper to prevent the accumulation of ore. Background Technology

[0002] In the mining and processing industry, belt conveyors are key equipment for material transportation, and cleaning scrapers, as an important component of belt conveyors, are mainly used to remove mineral materials adhering to the belt to ensure the normal operation of the belt. However, existing cleaning scraper technology has many problems in practical applications, especially the problem of mineral material accumulation, which seriously affects the normal operation and working efficiency of the equipment.

[0003] Existing traditional cleaning scrapers mostly adopt a fixed structural design, with their installation position and angle fixed and not adjustable. This results in poor adaptability when facing mineral materials with different characteristics. More prominently, existing scrapers generally have structural defects such as the installation position being too far from the funnel and the bottom plate being insufficient in length. This makes it impossible to effectively collect and guide the scraped mineral materials to the funnel, resulting in a large amount of mineral materials spilling onto the ground and forming accumulations.

[0004] To address this problem, we propose a scraper to prevent ore accumulation. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the existing technology where the installation position and angle of traditional scrapers are fixed and cannot be adjusted, resulting in poor adaptability, and the existing scraper installation position is too far from the funnel and the bottom plate length is insufficient, leading to a large amount of ore spillage and accumulation. Therefore, a scraper to prevent ore accumulation is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A scraper for preventing mineral accumulation includes a base plate. A support frame is fixedly connected to the upper surface of the base plate. Two first fixing blocks are fixedly connected to the inner wall of the support frame. A first screw is fixedly connected to the bottom surface of each of the two first fixing blocks. An adjusting block is slidably connected to the outer surface of the two first screws. A cleaning scraper is movably hinged inside the adjusting block. A first rotating shaft is fixedly connected inside the cleaning scraper. A worm gear is fixedly connected to the other end of the first rotating shaft. A worm is meshed with the outer surface of the worm gear. The rotation of the worm is connected inside the adjusting block. A gear commutator is fixedly connected to the left end of the worm. A second rotating shaft is fixedly connected to the input end of the gear commutator.

[0007] Preferably, the support frame has two rollers rotatably connected inside, and the outer surfaces of the two rollers are fitted with a belt, with the outer surface of the cleaning scraper in contact with the outer surface of the belt.

[0008] Preferably, the inner wall of the support frame is fixedly connected to two second fixing blocks, the bottom surface of each of the two second fixing blocks is fixedly connected to a second screw, the outer surface of the two second screws is slidably connected to a cleaning cylinder, and the outer surface of the cleaning cylinder is in contact with the outer surface of the belt.

[0009] Preferably, a limiting block is fixedly connected to the bottom surface of the adjusting block, and the second rotating shaft is rotatably connected inside the limiting block.

[0010] Preferably, a guide block is fixedly connected to the inner wall of the support frame, and the second rotating shaft is slidably connected inside the guide block.

[0011] Preferably, a funnel is fixedly connected to the upper surface of the base plate, and the funnel is located below the cleaning scraper.

[0012] Preferably, the right side of the funnel is fixedly connected to two locking blocks by bolts, and the opposite sides of the two locking blocks are jointly fixedly connected to a receiving plate.

[0013] Preferably, a handle is fixedly connected to the other end of the second rotating shaft. The outer surface of the handle is provided with a plurality of anti-slip grooves. Two first nuts are threadedly connected to the outer surface of each first screw, and two second nuts are threadedly connected to the outer surface of each second screw.

[0014] In summary, the technical effects and advantages of this utility model are as follows: 1. By using the handle to rotate to drive the second shaft, gear reversing device and worm gear to rotate, which in turn drives the worm wheel and the first shaft to rotate, the angle of the cleaning scraper can be precisely adjusted. Then, through the cooperation of the first screw and the adjusting block, the position of the cleaning scraper in the vertical direction can be adjusted to ensure that the optimal contact pressure with the belt is maintained, avoiding excessive tightness that would cause belt wear or excessive looseness that would affect the cleaning effect. This effectively adapts to the cleaning needs of different mineral materials and improves cleaning efficiency and effect. 2. By setting a receiving plate with a movable snap-fit ​​on the right side of the funnel, the scraped ore can be effectively received and guided into the funnel. This solves the problem of ore spillage and accumulation caused by the traditional scraper being installed too far from the funnel, and facilitates disassembly, maintenance and cleaning.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-5 A scraper for preventing ore accumulation includes a base plate 1. A support frame 2 is fixedly connected to the upper surface of the base plate 1. Two first fixing blocks 3 are fixedly connected to the inner wall of the support frame 2. A first screw 4 is fixedly connected to the bottom surface of each of the two first fixing blocks 3. An adjusting block 5 is slidably connected to the outer surfaces of the two first screws 4. A cleaning scraper 6 is hinged inside the adjusting block 5. A first rotating shaft 7 is fixedly connected inside the cleaning scraper 6. A worm gear 8 is fixedly connected to the other end of the first rotating shaft 7. A worm 9 is meshed with the outer surface of the worm gear 8. The rotation of the worm 9 is connected inside the adjusting block 5. The left end of the worm 9... A gear reversing device 10 is fixedly connected, and a second rotating shaft 11 is fixedly connected to the input end of the gear reversing device 10. By rotating the handle 12, the second rotating shaft 11, the gear reversing device 10, and the worm gear 9 are driven to rotate, which in turn drives the worm wheel 8 and the first rotating shaft 7 to rotate, so as to achieve precise adjustment of the angle of the cleaning scraper 6, effectively adapt to the cleaning needs of different mineral materials, and improve the cleaning efficiency and effect. Then, through the cooperation of the first screw 4 and the adjusting block 5, the position of the cleaning scraper 6 in the vertical direction can be adjusted to ensure that the optimal contact pressure with the belt 14 is maintained, so as to avoid the belt 14 being worn due to being too tight or the cleaning effect being affected by being too loose.

[0019] The support frame 2 has two rollers 13 connected to each other inside. The outer surfaces of the two rollers 13 are fitted with belts 14. The outer surface of the cleaning scraper 6 is in contact with the outer surface of the belt 14. The rollers 13 on the support frame 2 drive the belt 14 to move continuously. The cleaning scraper 6, supported by the adjusting block 5, maintains appropriate contact with the surface of the moving belt 14. Since the cleaning scraper 6 is fixed and the belt 14 moves continuously, relative motion is generated between the two, forming a scraping action, which removes the mineral material adhering to the belt 14 from the surface of the belt 14.

[0020] The inner wall of the support frame 2 is fixedly connected to two second fixing blocks 15. The bottom surface of each of the two second fixing blocks 15 is fixedly connected to a second screw 16. The outer surfaces of the two second screws 16 are slidably connected to a cleaning cylinder 17. The outer surface of the cleaning cylinder 17 is in contact with the outer surface of the belt 14. The design of the second fixing blocks 15 and the second screws 16 in conjunction with the cleaning cylinder 17 enables secondary cleaning of the belt 14, further improving the cleaning effect and preventing mineral residue.

[0021] The bottom surface of the adjusting block 5 is fixedly connected to the limiting block 18, and the second rotating shaft 11 is rotatably connected inside the limiting block 18. The limiting block 18 can ensure the stability of the rotation of the second rotating shaft 11.

[0022] A guide block 19 is fixedly connected to the inner wall of the support frame 2, and the second rotating shaft 11 is slidably connected inside the guide block 19. The guide block 19 can provide good vertical guidance for the second rotating shaft 11 when the cleaning scraper 6 is adjusted vertically.

[0023] A funnel 20 is fixedly connected to the upper surface of the base plate 1. The funnel 20 is located below the cleaning scraper 6 and can effectively receive the scraped-off ore material directly into the interior of the funnel 20.

[0024] Two locking blocks 21 are fixedly connected to the right side of the funnel 20 by bolts. The receiving plate 22 is fixedly connected to the opposite side of the two locking blocks 21. The connection between the receiving plate 22 and the funnel 20 is easy to disassemble and maintain, and can effectively receive the scraped mineral material and guide it into the inside of the funnel 20.

[0025] The other end of the second rotating shaft 11 is fixedly connected to a handle 12. The outer surface of the handle 12 is provided with several anti-slip grooves 23. The outer surface of each first screw 4 is threaded with two first nuts 24, and the outer surface of each second screw 16 is threaded with two second nuts 25. The anti-slip grooves 23 on the outer surface of the handle 12 can increase the friction between the operator's hand and the handle 12, improve the convenience and reliability of adjustment operation, and avoid slippage during operation. The first nuts 24 provide a locking function for adjusting the up and down position of the sweeping scraper 6. The sweeping cylinder 17 can be adjusted up and down through the second nuts 25 to ensure good contact with the belt 14 and ensure working stability.

[0026] The working principle of this utility model is as follows: During use, the roller 13 on the support frame 2 drives the belt 14 to move continuously. The cleaning scraper 6, supported by the adjusting block 5, maintains appropriate contact with the surface of the moving belt 14. Since the cleaning scraper 6 is fixed and the belt 14 moves continuously, relative motion is generated between the two, forming a scraping action to remove the mineral material adhering to the belt 14 from the surface of the belt 14. When it is necessary to adjust the angle between the cleaning scraper 6 and the belt 14 according to different mineral materials, the operator turns the handle 12. The handle 12 drives the second rotating shaft 11 to rotate. The second rotating shaft 11 transmits power to the gear reversing device 10, changes the transmission direction, and drives the worm 9 to rotate. According to the meshing relationship between the worm 9 and the worm wheel 8, the movement of the worm 9 is converted into the rotation of the worm wheel 8. Since the worm wheel 8 is fixedly connected to the first rotating shaft 7, the cleaning scraper 6 is driven to rotate with the first rotating shaft 7 to achieve angle adjustment. The self-locking characteristics of the worm wheel 8 and the worm 9 are used to ensure that the adjusted angle can be maintained stably and will not change due to working vibration. When the vertical position of the cleaning scraper 6 needs to be adjusted, loosen the first nut 24 on the first screw 4, move the adjusting block 5 up and down along the first screw 4 to adjust the height of the cleaning scraper 6. After adjusting to the appropriate position, tighten the first nut 24 to fix it, ensuring that the cleaning scraper 6 maintains the best contact pressure with the belt 14, so as to adapt to the cleaning needs of different thicknesses of mineral materials. Then, the second fixing block 15 and the second screw 16 on the support frame 2 cooperate with the cleaning cylinder 17 to achieve secondary cleaning of the belt 14. The cleaning cylinder 17 contacts the surface of the belt 14 to remove any residual mineral materials that may have remained after the initial cleaning. By adjusting the second nut 25 on the second screw 16, the vertical position can be changed. The vertical position of the cleaning cylinder 17 ensures good contact with the belt 14. Secondary cleaning can significantly improve cleaning efficiency and further reduce mineral residue. The mineral scraped off from the belt 14 by the cleaning scraper 6 will fall into the inside of the funnel 20 due to gravity. The mineral scraped off by the cleaning cylinder 17 will also fall into the inside of the funnel 20 in sequence after being guided by the inclined receiving plate 22. The funnel 20 and the receiving plate 22 are connected by a snap-fit ​​method, which is convenient for disassembly and can adjust the distance between the funnel 20 and the receiving plate 22 according to the different specifications of the snap-fit ​​blocks, ensuring that the mineral can be removed and effectively collected, avoiding equipment failure and deterioration of the working environment caused by mineral accumulation.
