Description
Technical Field
[0001] This utility model relates to the technical field of coal mine conveying equipment, specifically a coal mine belt conveyor with adjustable conveyor belt length. Background Technology
[0002] In coal mining and transportation operations, belt conveyors are the core equipment for achieving continuous and efficient coal transportation. Their conveying length needs to be flexibly adapted to actual working conditions such as the advancement of the mining face and the adjustment of the location of the transfer point.
[0003] Currently, most coal mine belt conveyors on the market suffer from inconvenient conveying length adjustment. Changing the conveying distance often requires disassembling and splicing the conveyor belt or adjusting the frame structure, which is cumbersome, time-consuming, and labor-intensive, severely impacting coal mining efficiency. Existing equipment lacks a stable guiding support structure, making the conveyor belt prone to deviation and swaying during operation. This not only affects conveying stability but may also cause coal spillage, increasing safety hazards. Furthermore, some conveyors have poorly designed spacing adjustment mechanisms, failing to flexibly adjust the conveyor belt spacing according to the coal conveying volume, easily leading to blockages or low conveying efficiency. Summary of the Invention

[0011] Beneficial effects
[0012] This utility model provides a coal mine belt conveyor with an adjustable conveyor belt length. Compared with the prior art, it has the following advantages: Through the telescopic mechanism, the first air pump drives the first air rod to extend and retract. The telescopic mechanism and the rolling mechanism work together to make the first air rod drive the rolling mechanism to move back and forth, thereby causing the rolling mechanism to drive the mounting frame to move synchronously, thus adjusting the conveying length. Through the conveying mechanism, the rolling guidance of the first and second guide shafts, combined with the support guide plate to support and limit the conveyor belt, effectively improves the stability of the conveyor belt during operation and avoids deviation and swaying. Moreover, the first adjusting bolt finely adjusts the angle and position of the support guide plate to optimize the guiding effect, reduce the risk of coal spillage, and ensure the continuity and safety of the conveying process. Through the spacing adjustment mechanism, the third air pump drives the third air rod to extend and retract. Since the second rotating plate is connected to the adjusting frame, the spacing between the conveyor belts can be precisely adjusted to flexibly adapt to different conveying needs according to changes in coal mining volume. This avoids material blockage caused by too small a spacing and low conveying efficiency caused by too large a spacing. Through the adjustment mechanism, the second air pump drives the second air rod to extend and retract, causing the folding plate to fold and unfold flexibly. Attached Figure Description

[0015] 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.
[0016] Example 1:
[0017] Please see Figure 1 - Figure 3 As shown, this embodiment proposes a coal mine belt conveyor with adjustable conveyor belt length, including: a mounting slide rail 1, a locking block 2 fixedly connected to one side of the mounting slide rail 1, a first fixing plate 3 fixedly connected to the other side of the mounting slide rail 1, a first fixing bolt 4 threadedly connected to the locking block 2 and the first fixing plate 3, a rolling mechanism and a telescopic mechanism provided on the upper surface of the mounting slide rail 1, the rolling mechanism including a mounting seat 5, a guide wheel 6 and a second fixing bolt 7, a mounting seat 5 provided on the upper surface of the mounting slide rail 1, a guide wheel 6 movably connected to one side of the mounting seat 5, and a pair of second fixing bolts 7 threadedly connected to one side of the mounting seat 5; When it is necessary to adjust the mounting base 5, the guide wheel 6 slides on the mounting slide rail 1 through the telescopic mechanism. When it is necessary to significantly adjust the conveying length, it can be adjusted.
[0018] The telescopic mechanism includes a first mounting frame 8, a first air pump 9, and a first air rod 10. The first mounting frame 8 is fixedly connected to one side of the mounting base 5, the first air pump 9 is fixedly connected to one side of the first mounting frame 8, and the first air rod 10 is fixedly connected to the output end of one side of the first air pump 9. The first air pump 9 drives the first air rod 10 to extend and retract. Since the output end of the first air rod 10 is connected to the first fixed plate 3, a pair of guide wheels 6 inside the first fixed plate 3 slide back and forth along the mounting slide rail 1.
[0019] like Figure 1 and Figure 2As shown, a conveying mechanism is also provided on one side of the first mounting frame 8. The conveying mechanism includes a second mounting frame 11, a first connecting plate 12, a first adjusting bolt 13, a support guide plate 14, a second connecting plate 15, a first guide shaft 16, a third connecting plate 18, and a second guide shaft 19. The second mounting frame 11 is fixedly connected to one side of the first mounting frame 8. A pair of first connecting plates 12 are fixedly connected to the upper surface of the second mounting frame 11. A pair of first adjusting bolts 13 are threaded into the inside of the pair of first connecting plates 12. Several support guide plates 14 are movably connected to one side of the pair of first connecting plates 12. Several second connecting plates 15 are fixedly connected to the upper surface of the second mounting frame 11. A plurality of first guide shafts 16 are movably connected to one side of the second connecting plate 15. A pair of horizontal plates 17 are fixedly connected inside the second mounting bracket 11. A pair of third connecting plates 18 are fixedly connected to one side of the pair of horizontal plates 17. A second guide shaft 19 is movably connected to one side of the pair of third connecting plates 18. A first mounting protective plate 20 is fixedly connected to the upper surface of the second mounting bracket 11. A second mounting protective plate 21 is fixedly connected to the upper surface of the second mounting bracket 11. A pair of second fixing plates 28 are movably connected to the upper surface of the second mounting protective plate 21. A second mounting bolt 29 is threaded inside the second fixing plate 28. A protective fence 30 is fixedly connected to the upper surface of the pair of second fixing plates 28. The protective fence 30 is attached to the upper surface of the second mounting protective plate 21 via a pair of second fixing plates 28 at the bottom. The second mounting bolts 29 inside the second fixing plates 28 are tightened to firmly fix the protective fence 30 to the second mounting protective plate 21. The first mounting protective plate 20 and the second mounting protective plate 21, fixed to the upper surface of the second mounting frame 11, form a two-sided protective barrier, together with the protective fence 30, constituting an all-around protective system. The conveyor belt is laid on the support surface formed by the first guide shaft 16, the second guide shaft 19, and the supporting guide plate 14. When the conveyor belt starts, the first guide shaft 16 rotates synchronously under the friction of the conveyor belt, guiding and limiting the movement of the conveyor belt on both sides, preventing... If the conveyor belt deviates or overturns during operation, the second guide shaft 19 rotates synchronously to provide rolling support for the bottom of the conveyor belt, reducing the running resistance of the conveyor belt and improving the smoothness of conveying. The support guide plate 14 further enhances the load-bearing stability of the conveyor belt through close contact with the conveyor belt, avoiding local sinking or deformation of the conveyor belt due to coal accumulation. The conveying mechanism is linked to the first air rod 10 of the telescopic mechanism through the second mounting frame 11. When the telescopic mechanism adjusts the conveying length, the second mounting frame 11 drives the entire conveying mechanism to extend and retract synchronously. The first guide shaft 16, the second guide shaft 19, and the support guide plate 14 always maintain a state of adaptation with the conveyor belt, ensuring that the conveying function is not affected after the length adjustment.
[0020] like Figure 2As shown, an adjustment mechanism is also provided on one side of the second mounting bracket 11. The adjustment mechanism includes a folding plate 22, a first connecting ring 23, a second connecting ring 24, a second air pump 25, a first mounting bolt 26, and a second air rod 27. The folding plate 22 is movably connected to one side of the second mounting bracket 11. The first connecting ring 23 is fixedly connected to one side of the folding plate 22. The second connecting ring 24 is fixedly connected to one side of the second mounting protective plate 21. The second air pump 25 is fixedly connected inside the second connecting ring 24. The first mounting bolt 26 is threadedly connected inside the second connecting ring 24 and the second air pump 25. The second air rod 27 is fixedly connected to the output end of one side of the second air pump 25. The second air pump 25 starts and drives the second air rod 27 to retract. Through the first connecting ring 23, the folding plate 22 is pulled to rotate inward around the connection point with the second mounting frame 11, realizing the folding action of the folding plate 22. This greatly reduces the lateral space occupied by the equipment. When it is necessary to extend the conveying path or expand the working surface, the second air pump 25 drives the second air rod 27 to extend, pushing the folding plate 22 to rotate outward around the connection point until the folding plate 22 and the second mounting frame 11 maintain a preset angle, forming a continuous support or conveying extension structure.
[0021] Preferred, such as Figure 3 As shown, a spacing adjustment mechanism is also provided on one side of the lower surface of the second mounting bracket 11. The spacing adjustment mechanism includes a base plate 31, a first rotating plate 32, a third air pump 33, a third air rod 34, a second rotating plate 35, and an adjustment frame 36. The base plate 31 is fixedly connected to the lower surface of the second mounting bracket 11. A pair of first rotating plates 32 are fixedly connected inside the base plate 31. A third air pump 33 is fixedly connected to one side of the pair of first rotating plates 32. A third air rod 34 is fixedly connected to the output end of one side of the third air pump 33. A second rotating plate 35 is fixedly connected to the output end of one side of the third air rod 34. An adjustment frame 36 is fixedly connected to one side of the second mounting bracket 11. One side of the second rotating plate 35 and one side of the adjustment frame 36 are connected to each other. When the third air rod 34 extends, it pushes the second rotating plate 35 to rotate around the connection point with the adjusting frame 36. This, in turn, causes the corresponding side of the second mounting frame 11 to shift outward through the adjusting frame 36, increasing the conveyor belt spacing. When the third air rod 34 retracts, it pulls the second rotating plate 35 to rotate in the opposite direction. This, in turn, causes the corresponding side of the second mounting frame 11 to shift inward through the adjusting frame 36, decreasing the conveyor belt spacing. This achieves stepless fine adjustment of the conveyor belt spacing to adapt to the needs of different coal conveying volumes or particle sizes.
[0022] In use, the device is first installed securely in the work area by using the locking block 2 on one side of the slide rail 1 and the first fixing plate 3 on the other side in conjunction with the first fixing bolt 4 with internal thread connection. At the same time, the protective fence 30 is attached to the upper surface of the second mounting protective plate 21 by a pair of second fixing plates 28 at the bottom and the second mounting bolt 29 is tightened to achieve a firm fixation. The first mounting protective plate 20 and the second mounting protective plate 21 on the second mounting frame 11 form a barrier on both sides, which together with the protective fence 30 constitute an all-round protection system to ensure work safety. According to the particle size and conveying volume requirements of the coal to be conveyed, the angle and spacing of the support guide plate 14 are finely adjusted by the first adjusting bolt 13 so that the first guide shaft 16, the second guide shaft 19 and the support guide plate 14 form a support and guide structure adapted to the conveyor belt. If a significant adjustment to the conveying length is required, first loosen a pair of second fixing bolts 7 on one side of the mounting base 5, start the first air pump 9 of the telescopic mechanism, which drives the first air rod 10 to perform telescopic movement. Since the first air rod 10 is connected to the first fixing plate 3, it drives the guide wheel 6 inside the mounting base 5 to slide smoothly along the mounting slide rail 1, and then drives the conveying mechanism to move as a whole through the first mounting frame 8. After reaching the preset position, tighten the second fixing bolts 7 to lock the guide wheel 6 inside the mounting base 5, start the second air pump 25 of the adjustment mechanism, drive the second air rod 27 to extend, and push the folding plate 22 to rotate outward around the connection point with the second mounting frame 11 to form a continuous conveying extension structure. When the working space is narrow or storage and transportation are required, drive the second air rod 27 to retract, pull the folding plate 22 to fold inward, and reduce the horizontal space occupied by the equipment. Depending on the coal particle size or conveying volume, if the conveyor belt spacing needs to be increased, the third air pump 33 of the start-up spacing adjustment mechanism drives the third air rod 34 to extend, pushing the second rotating plate 35 to rotate around the connection point with the adjustment frame 36. The adjustment frame 36 then drives the corresponding side of the second mounting frame 11 to shift outward. If the spacing needs to be decreased, the third air rod 34 retracts, pulling the second rotating plate 35 to rotate in the opposite direction, causing the corresponding side of the second mounting frame 11 to shift inward, thus achieving stepless fine adjustment of the conveyor belt spacing.
