Description

Technical Field

[0001] This utility model relates to gangue treatment, and more specifically, to a coal mine solid waste treatment device. Background Technology

[0002] During the production and processing of coal mines, a large amount of solid waste is generated as coal is mined and processed, mainly including coal gangue. Coal gangue is a blackish-gray rock with low carbon content and harder than coal that is associated with coal seams during the coal formation process.

[0003] In the coal mining process, efficient removal of gangue is a crucial aspect of ensuring production efficiency. Currently, common coal mine gangue removal equipment mainly adopts mechanical vibration, hydraulic drive, or tilting structures. For example, traditional tilting gangue removal equipment usually requires manual operation to tilt the container, which necessitates manual pushing, tilting, and cleaning operations. This manual intervention in lifting and tilting the container increases the labor intensity of operators, poses safety hazards, and has poor practicality and low gangue removal efficiency. In view of this, we propose a coal mine solid waste treatment device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem of poor practicality of current coal mine waste disposal equipment.

[0005] To achieve the aforementioned objectives and address the aforementioned problems, this utility model provides a coal mine solid waste treatment device, comprising a frame. Two guide wheels are fixedly connected to the lower surface of the frame's horizontal plates, and steel wire ropes are fitted around the outer surfaces of both guide wheels. A hopper is located on the lower side of the frame, and two connecting members are fixedly connected to the upper surface of the hopper. The connecting members are fixedly connected to the steel wire ropes. L-shaped connecting plates are fixedly connected to both sides of the hopper, and rotating shafts are fixedly connected to opposite sides of the two L-shaped connecting plates. Two grooves are formed on the surface of the rotating shafts. A first guide groove is formed on the adjacent side surface of the two front vertical plates of the frame. The rotating shafts are slidably connected to the interior of the first guide grooves via the grooves. A second guide groove is formed on the inner wall of the first guide groove, and a connecting component is provided inside the second guide groove.

[0006] As a preferred technical solution of this application, a mounting frame is fixedly connected between the two vertical plates on the rear side of the frame, and a conveyor belt is provided inside the mounting frame.

[0007] As a preferred technical solution of this application, the connecting component includes a first locking tooth, which is fixedly connected to the rear inner wall of the second guide groove, and the end of the rotating shaft away from the L-shaped connecting plate extends into the interior of the second guide groove.

[0008] As a preferred technical solution of this application, a transmission wheel is fixedly connected to one end of the rotating shaft located inside the second guide groove, and a second locking tooth is fixedly connected to the surface of the transmission wheel, the second locking tooth and the first locking tooth being compatible.

[0009] As a preferred technical solution of this application, both inner walls of the top of the first guide groove are provided with relief grooves, and the relief grooves are also connected to the second guide groove.

[0010] As a preferred technical solution of this application, a guide plate is provided on the rear side of the hopper, and fixed plates are fixedly connected to both sides of the hopper, with the guide plate located between the two fixed plates.

[0011] As a preferred technical solution of this application, a connecting rod is rotatably connected between the two fixed plates, the guide plate is fixedly sleeved on the outside of the connecting rod, and the two ends of the connecting rod respectively rotatably pass through the interior of the two fixed plates.

[0012] As a preferred technical solution of this application, both ends of the connecting rod are fixedly connected to circular plates, and a torsion spring is fixedly connected between the circular plates and the fixed plate, with the torsion spring movably sleeved on the outside of the connecting rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In the scheme of this application:

[0015] 1. The lifting of the hopper is achieved through the cooperation between the guide wheel and the wire rope. Subsequently, the hopper is flipped through the cooperation between the rotating shaft, transmission wheel, first chuck, second chuck, and other structures. This allows the internal waste material to be automatically dumped during the hopper's ascent without manual intervention. The hopper automatically resets itself during descent, greatly improving the efficiency of waste material processing in coal mines, reducing the workload and intensity of workers.

[0016] 2. The combination of guide plates, fixing plates, connecting rods and torsion springs facilitates the pouring of materials from inside the hopper onto the conveyor belt, making it easier to transfer waste materials later. Attached Figure Description

[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] Example 1

[0031] Please refer to Figure 1, Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 A coal mine solid waste treatment device includes a frame 1. Two guide wheels 2 are fixedly connected to the lower surface of the horizontal plate of the frame 1. Steel wire ropes 3 are sleeved on the outside of the two guide wheels 2. A hopper 4 is provided on the lower side of the frame 1. Two connectors 5 are fixedly connected to the upper surface of the hopper 4. The connectors 5 and the steel wire ropes 3 are fixedly connected. L-shaped connecting plates 6 are fixedly connected to both sides of the hopper 4. The axis of the rotating shaft 7 and the axis of the connector 5 are at the same height. The rotating shaft 7 is fixedly connected to the opposite side surface of the two L-shaped connecting plates 6. Two grooves 8 are opened on the surface of the rotating shaft 7. The first guide groove 9 is opened on the side surface of the two vertical plates on the front side of the frame 1 that are close to each other. The rotating shaft 7 is slidably connected to the inside of the first guide groove 9 through the grooves 8. A second guide groove 10 is opened on the inner wall of the first guide groove 9. A connecting component is provided inside the second guide groove 10.

[0032] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a mounting frame 15 is fixedly connected between the two vertical plates on the rear side of the frame 1, and a conveyor belt 16 is installed inside the mounting frame 15.

[0033] In the above embodiments, a drive device for traction of the wire rope 3 is also provided in conjunction with the guide wheel 2 and the wire rope 3. Since this is a conventional technical means in the art, it will not be described in detail here.

[0034] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the connecting assembly includes a first locking tooth 11, which is fixedly connected to the rear inner wall of the second guide groove 10, and the end of the rotating shaft 7 away from the L-shaped connecting plate 6 extends into the interior of the second guide groove 10.

[0035] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, a transmission wheel 12 is fixedly connected to one end of the rotating shaft 7 located inside the second guide groove 10. A second locking tooth 13 is fixedly connected to the surface of the transmission wheel 12. The second locking tooth 13 is compatible with the first locking tooth 11. When the hopper 4 drives the L-shaped connecting plate 6 to move, the L-shaped connecting plate 6 will drive the rotating shaft 7 to move inside the first guide groove 9 and the second guide groove 10. At this time, the rotating shaft 7 will not rotate under the restriction of the groove 8.

[0036] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the inner walls on both sides of the top of the first guide groove 9 are provided with relief grooves 14, which are also connected to the second guide groove 10. When the rotating shaft 7 drives the transmission wheel 12 to engage with the first locking tooth 11 and the second locking tooth 13, the rotating shaft 7 will simultaneously enter the interior of the relief groove 14. At this time, the transmission wheel 12 will be driven to rotate under the cooperation of the first locking tooth 11 and the second locking tooth 13. The rotation of the transmission wheel 12 can drive the rotation of the rotating shaft 7, and the rotation of the rotating shaft 7 can drive the rotation of the L-shaped connecting plate 6, thereby driving the hopper 4 to flip over, so as to facilitate the subsequent dumping of the internal waste.

[0037] Example 2

[0038] The coal mine solid waste treatment device provided in Example 1 is further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a guide plate 17 is provided on the rear side of the hopper 4, and fixed plates 18 are fixedly connected to both sides of the hopper 4. The guide plate 17 is located between the two fixed plates 18. When the hopper 4 is flipped, the waste inside the hopper 4 will slide down through the guide plate 17 to the upper side of the conveyor belt 16 to facilitate the conveying of the waste.

[0039] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a connecting rod 19 is rotatably connected between two fixed plates 18, and a guide plate 17 is fixedly sleeved on the outside of the connecting rod 19. The two ends of the connecting rod 19 rotatably pass through the interior of the two fixed plates 18 respectively.

[0040] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, circular plates 20 are fixedly connected to both ends of the connecting rod 19. A torsion spring 21 is fixedly connected between the circular plate 20 and the fixed plate 18. The torsion spring 21 is movably sleeved on the outside of the connecting rod 19. When the guide plate 17 is subjected to the pressure of the waste material and flips downward, the torsion spring 21 will simultaneously generate elastic deformation until the guide plate 17 contacts the top surface of the mounting frame 15. Subsequently, the waste material inside the hopper 4 can slide down through the guide plate 17. At the same time, under the restriction of the torsion spring 21, when the guide plate 17 is not subjected to external force, the guide plate 17 will always be in contact with the hopper 4, thereby avoiding interference between the mounting frame 15 and the guide plate 17.

[0041] In the above embodiment, in order to prevent waste from falling outside the conveyor belt 16, baffles can be set on both sides of the mounting frame 15 to prevent waste from falling.

[0042] The coal mine solid waste treatment device provided by this utility model is used as follows:

[0043] By feeding waste material into the hopper 4, the hopper 4 can be moved upwards by the external drive device and the cooperation between the guide wheel 2 and the wire rope 3. The movement of the hopper 4 will drive the L-shaped connecting plate 6 to move. At the same time, when the hopper 4 moves the L-shaped connecting plate 6, the L-shaped connecting plate 6 will drive the rotating shaft 7 to move inside the first guide groove 9 and the second guide groove 10. At this time, the rotating shaft 7 will not rotate due to the restriction of the groove 8. The rotating shaft 7 will also drive the transmission wheel 12 to move inside the second guide groove 10. When the rotating shaft 7 drives the transmission wheel 12 to engage with the first locking tooth 11 and the second locking tooth 13, the rotating shaft 7 will simultaneously enter the interior of the clearance groove 14. At this time, the engagement of the first locking tooth 11 and the second locking tooth 13 will drive the transmission wheel 12 to rotate. The rotation of the transmission wheel 12 will drive the rotation of the rotating shaft 7. The rotation of the rotating shaft 7 will drive the rotation of the L-shaped connecting plate 6, thereby causing the hopper 4 to flip over, so as to facilitate the subsequent dumping of the waste material inside.

[0044] When the hopper 4 is flipped, the guide plate 17 will be flipped downward by the pressure of the waste material, and the torsion spring 21 will simultaneously generate elastic deformation until the guide plate 17 and the top surface of the mounting bracket 15 come into contact, and the waste material inside the hopper 4 can then slide down through the guide plate 17.
