Description

Technical Field

[0001] This invention relates to the field of coal mine processing, and more particularly to a coal cleaning device for underground belt conveyor roadways in coal mines. Background Technology

[0002] During the production and transportation of fully mechanized mining tunnels, a large amount of coal spills from both sides of the self-moving tail and the sides of the conveyor belt in the mining and transportation roadways. This not only causes a certain degree of coal loss, but also seriously affects the safety of passage on both sides of the transportation roadway. At the same time, a large part of the spilled coal enters the bottom of the conveyor belt, forming a thick layer of coal and coal sludge at the bottom of the conveyor belt. This is very inconvenient to clean up. When the thickness reaches the bottom of the conveyor belt, it will seriously affect the smoothness of the conveyor belt transportation and the service life of the conveyor belt, causing unnecessary safety hazards.

Detailed Implementation

[0031] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0032] Example:

[0033] Please combine Figure 1-11 ,

[0034] A coal cleaning device for an underground belt conveyor roadway in a coal mine includes: a conveyor belt 1, with a blocking mechanism 2 connected in the middle. The conveyor belt 1 carries coal for necessary transport. The blocking mechanism 2 obstructs and guides the coal in the conveyor belt 1 below, leading it into a collection mechanism 3. The collection mechanism 3 is located below the blocking mechanism 2. A cleaning mechanism 4 is located on one side of the conveyor belt 1 and cooperates with the collection mechanism 3. The cleaning mechanism 4 moves back and forth around the perimeter of the conveyor belt 1 to collect fallen coal. The cleaning mechanism 4 can be equipped with an existing route system or installed with a designated guide rail to move along a designated path as needed.

[0035] The cleaning mechanism 4 includes: a vehicle body 5, with a motor fixedly connected inside the vehicle body 5, providing power to other mechanisms requiring power via an existing transmission mechanism and gearbox; an execution unit 6, fixedly connected inside the vehicle body 5; a sorting box 8 located inside the vehicle body 5 connecting two execution units 6; a filter chamber 13 inside the sorting box 8; a filter pipe 15 connected to the execution unit 6 on one side of the filter chamber 13; and a crushing unit 6 for easy transportation. External coal, after being collected by the cleaning unit 12, enters the filter chamber 13 through the rotating pipe 11 and the fixed pipe 16, achieving preliminary sorting before entering the execution unit 6 for further processing. The fixed pipe 16 has one end fixedly connected to the sorting box 8, and the other end rotatably connected to the rotating pipe 11 via a rotary joint. The cleaning unit 12 is fixedly connected to the bottom end of the rotating pipe 11, and performs collection and cleaning... The vehicle consists of a sweeping system, a power pump 44 fixedly connected inside the vehicle body 5, with its input end connected to a motor drive. A transport pipe 7 is connected to the top of the power pump 44. The power pump 44 operates within the vehicle body 5, generating negative pressure to draw in external coal. Simultaneously, the processed coal is transported through the transport pipe 7. A water collection tank 42, located inside the vehicle body 5, has an overflow pipe 43 connected to the power pump 44 on one side. The water collection tank 42 temporarily stores water, which then flows into the power pump 44 through the overflow pipe 43, achieving humidification and reducing dust. A connecting pipe 40 connects one end to the collection mechanism 3 and the other end to the water collection tank 42, allowing for the addition of water to the tank. An actuating rod 41 works in conjunction with the collection mechanism 3. Tracked wheels 10 are connected to the bottom of the vehicle body 1. The actuating rod 41 triggers the tracked wheels 10, which rotate via a motor drive, thus enabling overall movement.

[0036] The transport pipe 7 includes a main pipe 48 fixedly connected to a power pump 44. A protrusion 47 is integrally formed on the top side of the main pipe 48. A centralized funnel 46 is connected to the protrusion 47. Multiple vent holes 45 are connected to the main pipe 48. The main pipe 48 transports gas. The protrusion 47 increases the gas flow path and reduces the pressure. Atmospheric pressure forces external gas into the main pipe 48, forming an inward flow. This prevents dust leakage and facilitates the addition of new coal from the centralized funnel 46. The gas mixed with coal slag passes through the vent holes 45, causing the gas to overflow. The coal slag falls onto the belt 1 under gravity, reducing the overflow of dust blown by the gas.

[0037] The cleaning unit 12 includes a fixed rod 14 fixedly connected to the vehicle body 1. A cam 59 is fixedly connected to the bottom end of the fixed rod 14. A rotating box 37 is fixedly connected to the bottom end of the rotating tube 11. The rotating tube 11 is connected to the output end of the motor through a transmission assembly, meaning that the rotating tube 11 can rotate periodically. A vertical rod 56 is rotatably connected to the edge of the rotating box 37. A first rod 57 and a second rod 62 are connected to the vertical rod 56. A bending rod 54 is fixedly connected to one end of the second rod 62. A follower column 60 is rotatably connected to the other end of the first rod 57. A guide groove 61 is provided between the rotating box 37 and the cam 59. The follower column 60 and the guide groove 61... The sliding sleeve, during the periodic rotation of the rotating tube 11, drives the first rod 57 to move. Under the constraint of the guide groove 61, the first rod 57 and the second rod 62 rotate, realizing periodic expansion and contraction, and gathering and collecting the surrounding coal slag. The bottom of the rotating box 37 is provided with multiple suction holes 38. Multiple crushing blades 39 located inside the rotating box 37 are fixedly connected to the outer wall of the fixed rod 14. Under the negative pressure generated by the power pump 44, the external gas mixed with coal slag enters the rotating box 37 through the suction holes 38. The mixed gas causes the coal slag to collide with the crushing blades 39, resulting in initial crushing, which facilitates subsequent transportation.

[0038] The execution unit 6 includes a fixed box 17 fixedly connected to the vehicle body 5. The fixed box 17 is sealed as necessary. A disturbance component 18 is connected to the top of the fixed box 17. A cutting rod 24 is connected to the output end of the disturbance component 18. Multiple cutting blades 20 are fixedly connected to the outer wall of the cutting rod 24. Driven by the disturbance component 18, the cutting rod 24 drives the cutting blades 20 to rotate and swing. An impact hammer 21 is fixedly connected to the bottom end of the cutting rod 24. A forming block 22 is fixedly connected to the fixed box 17 below the impact hammer 21. The impact hammer 21 and the forming block 22 cooperate with each other to perform impact crushing. A suction pipe 23 connected to a power pump 44 is fixedly connected to one side of the fixed box 17. The power pump 44 sucks up the processed coal slag through the suction pipe 23.

[0039] The disturbance component 18 includes a transmission rod 27 connected to a motor drive. The transmission rod 27 is connected to a transmission assembly 28, which is connected to an upper power shaft 29 and a drive disc 33. The upper power shaft 29 is connected to a lower power shaft 30 via a universal coupling. An upper plate 32 is fixedly connected to the bottom end of the lower power shaft 30. A second spring 36 is fixedly connected to the lower side of the upper plate 32. The other end of the second spring 36 is fixedly connected to a lower plate 25 fixedly connected to a cutting rod 24. A rotating plate 35 is rotatably connected to the middle of the lower plate 25. The upper side is rotatably connected to the connecting rod 34, which is rotatably connected to the drive disk 33. The lower plate 25 is fixedly connected to the vertical rod 31, which is slidably sleeved with the upper plate. The transmission assembly 28 is connected to the output end of the motor, so that the torque of the motor is transmitted to the upper power shaft 29 and the drive disk 33. The upper power shaft 29 is transmitted to the lower power shaft 30 and the lower plate 25 through a universal coupling, so that the cutting rod 24 rotates to realize rotary cutting. At the same time, the drive disk 33 rotates, which drives the rotating plate 35 under the connecting rod 34 to move up and down, and then causes the lower plate 25 to move up and down, forming an impact.

[0040] The fixed box 17 has an integrally formed separation box 19. The disturbance component 18 is located inside the separation box 19. The separation box 19 is equipped with a control unit. The outer wall of the lower plate 25 is rotatably connected to a flexible cover 26 that is fixedly connected to the separation box 19. The control unit controls various electronic components, and the flexible cover 26 provides dust protection.

[0041] The cleaning mechanism 4 includes a stabilizing box 72, a hydraulic cylinder 65 fixedly connected inside the stabilizing box 72, a support frame fixedly connected to the hydraulic cylinder 65, a collection box 64 placed on the support frame, an elastic rope 71 fixedly connected to one side of the collection box 64 and rotatably connected to the stabilizing box 72, actuating tubes 68 fixedly connected to both sides of the stabilizing box 72, a vertical tube 69 connected to one of the actuating tubes 68, a guide plate 70 connected to the stabilizing box 72 at the other end of the vertical tube 69, and a volumetric box 73 fixedly connected to one side of the stabilizing box 72, with a sliding sleeve inside the volumetric box 73. A push plate 74 is provided, and a contact plate 75 is fixedly connected to one side of the push plate 74. A guide pipe 67 connected to the hydraulic cylinder 65 is connected to one side of the volume box 73. After the 41 contacts the contact plate 75, the push plate 74 moves, allowing the liquid inside to enter the hydraulic cylinder 65 through the guide pipe 67, causing the collection box 64 to rise. After reaching a certain height, it tilts under the action of the elastic rope 71, allowing the coal slag to enter the centralized funnel 46 for addition and transportation. At the same time, the trigger pipe 68 and the connecting pipe 40 are interconnected to add water.

[0042] Both the actuating pipe 68 and the connecting pipe 40 include an outermost outer pipe 49. A screen plate 53 is fixedly connected inside the outer pipe 49. A spring 50 is fixedly connected to one side of the screen plate 53, and a contact pipe 54 that slides and fits with the outer pipe 49 is fixedly connected to the other end of the spring 50. A guide frame 51 is fixedly connected inside the contact pipe 54. A sealing ring 52 that engages with the screen plate 53 is fixedly connected to one side of the guide frame 51. The two contact pipes 5 in the actuating pipe 68 and the connecting pipe 40 are interlocked. After contacting each other to a certain extent, they squeeze the spring 50, causing the contact pipe 54 and the guide frame 51 to move, which in turn causes the sealing ring 52 to move, thus forming a passage in the pipe and realizing water supply.

[0043] The blocking mechanism 2 includes an intermediate shaft 65, and a rotating rod 64 is rotatably sleeved on the outer wall of the intermediate shaft 65. A cleaning strip 63 is fixedly connected to the lower side of the rotating rod 64. The slag is blocked by the rotating rod 64, causing it to accumulate and enter the rotating rod 64 through the guide plate 70.

[0044] The implementation principle of this application embodiment is as follows: Firstly, the blocking mechanism 2 is installed on the feeding end of the conveyor belt 1, and then the collecting mechanism 3 is fixed on both sides. Simultaneously, the cleaning mechanism 4 is moved to its initial position. After the transport begins, the cleaning mechanism 4 works synchronously. The motor drives the 10 to move. During this movement, the rotating tube 11 rotates, the power pump 44 works, and the rotating tube 11 drives the first rod 57 to move. Under the constraint of the guide groove 61, the first rod 57 and the second rod 62 rotate, achieving periodic expansion and contraction, gathering and collecting the surrounding coal slag. Under the negative pressure generated by the power pump 44, external gas mixed with coal slag enters the rotating box 37 through the suction hole 38. The mixed gas causes the coal slag to impact the crushing blade 39, resulting in initial crushing. Then, it enters the filter chamber 13 for preliminary classification, and then passes through the filter tube 15 into the execution unit 6. The torque of the motor is transmitted to the upper power shaft 29 and the drive disc 33. The upper power shaft 29 is connected to a universal coupling. The transmission is transmitted to the lower power shaft 30 and the lower plate 25, causing the cutting rod 24 to rotate and achieve rotary cutting. At the same time, the drive disc 33 rotates, causing the rotating plate 35 under the connecting rod 34 to move up and down, which in turn causes the lower plate 25 to move up and down, forming an impact. With the help of other auxiliary components, the coal slag is crushed. Finally, the fallen coal slag is returned to the main pipe 48. During the periodic collection process, the two contact pipes 5 in the trigger pipe 68 and the connecting pipe 40 are interlocked. After contacting to a certain extent, they squeeze the spring 3 50, causing the contact pipe 54 and the guide frame 51 to move. This causes the sealing ring 52 to move, forming a passage in the pipeline to supply water. At the same time, after 41 contacts the contact plate 75, it causes the push plate 74 to move, allowing the liquid inside to enter the hydraulic cylinder 65 through the guide pipe 67, causing the collection box 64 to rise. After reaching a certain height, under the action of the elastic rope 71, it tilts, allowing the coal slag to enter the centralized funnel 46 for addition and transportation, completing one cycle of collection.

[0045] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
