Description

Technical Field

[0001] The present invention relates to the technical field of buffer idlers, and particularly to a support for a buffer idler group of a mining conveyor belt. Background Art

[0002] In the mining industry, the conveyor belt is a key equipment for material transportation. When different conveyor belts transport materials, due to differences in material characteristics, transportation distance, environment and other factors, different requirements are imposed on the angle of the idler support. If the angle of the roller frame is unreasonable, large-angle friction will occur between the belt and the idler, resulting in increased resistance and affecting production efficiency. Secondly, it is quite common for the belt to be unevenly stressed during operation. Excessive local pressure is likely to cause excessive wear of the belt, and the offset of the support center of gravity will cause vibration and shaking, reducing the stability and reliability of the entire buffer idler group support. Moreover, the mining environment usually has a large amount of dust, and it is extremely easy for dust to accumulate at the connection between the buffer roller and the support rod. This dust generates additional friction when the buffer roller rotates, accelerating component wear and may also cause abnormal rotation of the buffer roller, leading to problems such as belt deviation. When encountering different degrees of dust accumulation, the dust cleaning equipment with a fixed cleaning intensity and speed cannot respond flexibly. Finally, belt deviation will cause downtime for adjustment, affecting the continuity and stability of the conveying operation and reducing production efficiency. For this reason, we propose a support for a buffer idler group of a mining conveyor belt. Summary of the Invention

[0014] Compared with the prior art, the advantages and positive effects of the present invention are:

[0015] 1. The present invention proposes a buffer roller group support for a mining conveyor belt machine, which drives a lifting block to move up and down along a limit frame through a cylinder, and the lifting block drives a threaded rod to rotate through a rotating rod, and the threaded rod drives a second support rod to rotate through a third support rod. The rotation of the second support rod can drive the second buffer roller on the surface to change the inclination angle, and the opening angle of both sides of the belt can be adjusted at this time. According to different belt conveyors, the angle of the roller support is reasonably adjusted to ensure that the belt runs smoothly during transmission. At the same time, it can effectively avoid the roller frame angle being too large or too small, and large-angle friction between the belt and the roller, and the corresponding increase in resistance. The increase in resistance will lead to an increase in power consumption of the belt conveyor, affecting the production efficiency of the equipment.

[0016] 2. The present invention proposes a mining conveyor belt buffer roller group support, which, when adjusting the angle of the second buffer roller in the roller group support, drives the rotating rod to rotate through the second motor, and drives the second buffer roller on the surface to slide along the direction of the limiting slide groove through the threaded rod. When the two second support rods are opened, the second buffer roller moves downward, and when the two second support rods are gathered together, the second buffer roller moves upward. The position of the second buffer roller can be adjusted to effectively improve the force condition between the belt and the support cylinder, so that the force on the belt is more uniform during operation, and excessive wear caused by excessive local pressure can be avoided. At the same time, the dual adjustment of the inclination angle and position of the support cylinder can accurately adjust its center of gravity distribution, so that the entire buffer roller group support is more stable during operation, and the vibration and shaking caused by the center of gravity shift are reduced, which greatly improves the stability and reliability of the equipment, reduces the risk of equipment failure, and ensures the continuous production.

[0017] 3. The present invention provides a buffer idler group support for a mining conveyor belt. When dust cleaning is required, the rotating cylinder is driven to rotate by the first motor. The rotating cylinder drives the threaded cylinder to rotate through the lead screw. The threaded cylinder drives the mounting frame to rotate through the sliding frame. The mounting frame drives the support plate to deflect and shake through the spherical block. The support plate drives the positioning sleeve to shake through the positioning rod and the positioning ball. The positioning sleeve drives the push plate to shake inside the positioning cylinder through the push rod. The push plate drives the spur gear to rotate through the rack. The spur gear drives the rotating frame to rotate through the toothed ring. The rotating frame drives the cleaning brush to rotate. At this time, the connection between the first support rod and the first buffer idler can be cleaned of surface dust in a timely manner. Dust accumulation at the connection is likely to cause friction during the rotation of the buffer idler, accelerating component wear. Regular dust cleaning can effectively reduce frictional losses, extend the service life of the support rod and the buffer idler, ensure the buffer idler rotates smoothly, improve the operating stability of the entire conveying system, and avoid problems such as belt deviation caused by abnormal buffer idlers.

[0018] 4. The present invention provides a buffer idler group support for a mining conveyor belt. When the cleaning intensity needs to be adjusted, by rotating the lead screw, the lead screw drives the threaded cylinder to move. At this time, the sliding frame slides on the mounting frame and deflects. The deflection of the sliding frame drives the mounting frame to deflect. The mounting frame drives the spherical block to deflect on the inner edge of the rotating cylinder. The farther the threaded cylinder is from the center of the lead screw, the higher the cleaning intensity. In the case of less dust, the rotating cleaning speed can be reduced, which not only meets the dust cleaning requirements but also avoids unnecessary energy consumption and equipment wear caused by excessive cleaning. In a harsh environment with a large amount of dust, the rotating cleaning speed can be increased to quickly remove the accumulated dust and ensure the normal operation of the equipment. When abnormal dust accumulation occurs in the connection area between the first buffer idler and the first support rod, the rotating cleaning speed of this area can be increased to timely solve the local dust accumulation problem.

[0019] 5. The present invention provides a buffer idler group support for a mining conveyor belt. When belt deviation correction is required during conveying, the third motor drives the rotating rod to rotate. The rotating rod drives the connecting rod to rotate through the rotating plate. The connecting rod drives the lifting block to rotate through the limiting frame. The lifting block drives the second buffer idler to rotate along the arc groove through the threaded rod. At this time, the horizontal angle of the second buffer idler can be adjusted to facilitate belt deviation correction. By adjusting the horizontal angle of the inclined second buffer idler, the deviation during the belt operation can be corrected in real time, keeping the belt always on the correct conveying track, avoiding frequent shutdown adjustments caused by belt deviation, ensuring the continuity and stability of the conveying operation, and improving production efficiency.

A threaded cylinder 24 is rotatably connected to the outer surface of the sliding frame 23 through a bearing. A lead screw 25 is rotatably connected to the inner surface of the rotating cylinder 11 through a bearing. The lead screw 25 is threadedly connected to the threaded cylinder 24.

[0034] The effect is that the sliding frame 23 drives the mounting frame 22 to rotate, the mounting frame 22 drives the spherical block 12 to rotate, the spherical block 12 drives the support plate 13 to deflect and shake, the support plate 13 drives the positioning rod 14 to shake, the positioning rod 14 drives the positioning ball 15 to shake, the positioning ball 15 drives the positioning sleeve 16 to shake, the positioning sleeve 16 drives the push plate 19 to shake inside the positioning cylinder 18 through the push rod 17, the push plate 19 drives the rack 3 to move, by rotating the lead screw 25, the lead screw 25 drives the threaded cylinder 24 to move.

The limit slider 32 is slidably connected to the limit sliding groove 33. The upper surface of the base 1 is fixedly connected to the limit frame 34. The lifting block 31 is slidably connected to the limit frame 34. The inner surface of the limit frame 34 is fixedly installed with a cylinder 35.

[0036] The effect is that the cylinder 35 drives the lifting block 31 to move up and down along the limit frame 34. The lifting block 31 drives the rotating rod 30 to move. The rotating rod 30 drives the threaded rod 29 to rotate. The threaded rod 29 drives the third support rod 28 to rotate. The third support rod 28 drives the second support rod 26 to rotate. When the lifting block 31 moves down, the third support rod 28 approaches the second support rod 26. When the lifting block 31 moves up, the third support rod 28 moves away from the second support rod 26. At the same time, while the third support rod 28 slides with the second support rod 26, the third support rod 28 can drive the second support rod 26 to rotate. The rotation of the second support rod 26 can drive the second buffer roller 27 on the surface to change the inclination angle. At this time, the opening angle on both sides of the belt can be adjusted. At the same time, during the adjustment, the rotating rod 30 drives the threaded rod 29 to rotate through the rotating shaft. The threaded rod 29 drives the second buffer roller 27 on the surface to slide along the direction of the limit sliding groove 33. At the same time, the dual adjustment of the inclination angle and position of the support cylinder can accurately adjust its center of gravity distribution.

[0037] AsFigure 1 - Figure 8 As shown in the figure, a rotating rod 36 is rotatably connected to the lower surface of the base 1 through a bearing. A rotating plate 37 is fixedly connected to the outer surface of the rotating rod 36. A connecting rod 38 is fixedly connected to the lower surface of the limiting frame 34. An arc-shaped groove 39 is formed in the outer surface of the base 1. The connecting rod 38 is slidably connected to the arc-shaped groove 39. The rotating plate 37 is fixedly connected to the connecting rod 38. Semi-gear 40 is fixedly connected to the outer surfaces of both the rotating rod 36 and the connecting rod 38.

[0038] The effect is that the third motor 43 drives the rotation of the rotating rod 36. The rotating rod 36 drives the rotation of the rotating plate 37. The rotating plate 37 drives the rotation of the connecting rod 38. The connecting rod 38 drives the rotation of the upper limiting frame 34. The limiting frame 34 drives the rotation of the lifting block 31. The lifting block 31 drives the rotation of the threaded rod 29. The threaded rod 29 drives the second buffer roller 27 to rotate along the arc-shaped groove 39. At this time, the horizontal angle of the second buffer roller 27 can be adjusted to facilitate belt deviation correction.

[0039] Working principle: During operation, the belt is placed on the first buffer roller 10 and the second buffer roller 27. At this time, the first buffer roller 10 and the second buffer roller 27 can support the belt, and ore blocks are placed on the belt for transportation. When the angle of the belt needs to be adjusted, the cylinder 35 drives the lifting block 31 to move up and down along the limiting frame 34. The lifting block 31 drives the rotating rod 30 to move, the rotating rod 30 drives the threaded rod 29 to rotate, the threaded rod 29 drives the third support rod 28 to rotate, and the third support rod 28 drives the second support rod 26 to rotate. When the lifting block 31 moves downward, the third support rod 28 approaches the second support rod 26. When the lifting block 31 moves upward, the third support rod 28 moves away from the second support rod 26. At the same time, while the third support rod 28 slides with the second support rod 26, the third support rod 28 can drive the second support rod 26 to rotate. The rotation of the second support rod 26 can drive the second buffer roller 27 on its surface to change the inclination angle, and at this time, the opening angle on both sides of the belt can be adjusted. At the same time, during the adjustment, the second motor 42 drives the rotating rod 30 to rotate, the rotating rod 30 drives the threaded rod 29 to rotate through the rotating shaft, and the threaded rod 29 drives the second buffer roller 27 on its surface to slide along the direction of the limiting chute 33. When the two second support rods 26 open, the second buffer roller 27 moves downward. When the two second support rods 26 gather, the second buffer roller 27 moves upward. During long-term use of the first support rod 6, since the first buffer roller 10 rotates on its surface, dust is likely to enter between the first buffer roller 10 and the first support rod 6 during the transportation of ore, resulting in a reduction in the rotation effect. When dust removal is required, the first motor 41 drives the rotating cylinder 11 to rotate, the rotating cylinder 11 drives the lead screw 25 to rotate, the lead screw 25 drives the threaded cylinder 24 to rotate, the threaded cylinder 24 drives the sliding frame 23 to rotate, the sliding frame 23 drives the mounting frame 22 to rotate, the mounting frame 22 drives the spherical block 12 to rotate, the spherical block 12 drives the support plate 13 to deflect and shake, the support plate 13 drives the positioning rod 14 to shake, the positioning rod 14 drives the positioning ball 15 to shake, the positioning ball 15 drives the positioning sleeve 16 to shake. The positioning sleeve 16 is provided with a through hole at the bottom for the positioning rod 14 to pass through. The positioning sleeve 16 drives the push plate 19 to shake inside the positioning cylinder 18 through the push rod 17. The push plate 19 drives the rack 3 to move, the rack 3 drives the spur gear 4 to rotate, the spur gear 4 drives the toothed ring 8 to rotate, the toothed ring 8 drives the rotating frame 7 to rotate, and the rotating frame 7 drives the cleaning brush 9 to rotate and clean the dust on its surface. When the cleaning intensity needs to be adjusted, by rotating the lead screw 25, the lead screw 25 drives the threaded cylinder 24 to move. At this time, the sliding frame 23 slides on the mounting frame 22 and deflects. The deflection of the sliding frame 23 drives the mounting frame 22 to deflect. The mounting frame 22 drives the spherical block 12 to deflect inside the rotating cylinder 11. The threaded cylinder 24 is farther away from the center of the lead screw 25, and the higher the cleaning intensity. When the belt during transportation needs to be corrected, the third motor 43 drives the rotating rod 36 to rotate, and the rotating rod 36 drives the rotating plate 37 to rotate.The rotating plate 37 drives the connecting rod 38 to rotate. The connecting rod 38 drives the limiting frame 34 at the top to rotate. The limiting frame 34 drives the lifting block 31 to rotate. The lifting block 31 drives the threaded rod 29 to rotate. The threaded rod 29 drives the second buffer roller 27 to rotate along the arc-shaped groove 39. At this time, the horizontal angle of the second buffer roller 27 can be adjusted.
