Description

Technical Field

[0001] The invention relates to the field of mine coal slime cleaning, and in particular to an intelligent cleaning device for a mine belt conveyor head. Background Art

[0002] Coal conveyor belt is one of the important equipment for underground coal mining. It is usually used to transport coal from the mine to the ground.

[0003] The head of the mining machine belt conveyor is the end point of the belt transport of gangue, because a lot of broken slag and gravel will be produced during the tunnel transportation, and water will flow onto the belt during use. There is a lot of coal ash on the belt, and the coal ash is mixed with water to form coal slime that adheres to the belt. When it reaches the head of the belt conveyor, some of the coal slime adhered to the belt will be thrown into the water channel under the head of the belt conveyor, among which small pieces of coal slime will be washed away by the water flow in the water channel, and large pieces of coal slime will adhere to the side walls and the bottom of the water channel. After long-term accumulation, the coal slime will stick together and form a very thick coal slime layer. During manual cleaning, due to the narrow water channel, different actions are required to shovel coal slime at different depths during the cleaning process, which affects the cleaning efficiency. In addition, due to the large adhesion of coal slime, it takes a lot of force to clean it, resulting in unsatisfactory manual cleaning effect. After large pieces of coal slime are directly recovered, the water inside it is difficult to discharge quickly, affecting recycling. Summary of the invention

DETAILED DESCRIPTION

[0032] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0033] Embodiment 1: A mine belt conveyor head intelligent cleaning device, such as Figures 1-12As shown in the figure, it includes an orbit 1, a walking wheel bracket 101, a screening box 102, a treatment box 103, a mounting frame 104, a front shovel plate 1041, a slime conveyor belt 105, a control motor 106, a transmission shaft 107, a collecting belt transmission member 108, a rotary collecting device and a depth adjustment assembly. A water channel with the same width as the mine belt conveyor is excavated on the ground of the mine belt conveyor in the mine. Tracks 1 are laid on both sides of the water channel at a certain height from the ground. The screening box 102 and the treatment box 103 are connected to the walking wheel bracket 101, and the screening box 102 and the treatment box 103 are located at the top of the walking wheel bracket 101. Wheels are installed in the walking wheel bracket 101, and the wheels are in contact with the top of the track 1. The front end of the screening box 102 is fixedly connected with a mounting frame 104. A front shovel plate 1041 is provided at the front end of the mounting frame 104. The front shovel plate 1041 is used to shovel up the slime deposited at the bottom of the water channel. A slime conveyor belt 105 is installed in the mounting frame 104. The slime conveyor belt 105 is used to convey the slime shoveled up by the front shovel plate 1041 into the screening box 102. Elastic partitions are evenly spaced on the slime conveyor belt 105 to prevent the slime from sliding down. Drainage holes are provided on the slime conveyor belt 105 and the front shovel plate 1041. A control motor 106 is installed outside the treatment box 103. A transmission shaft 107 is installed in the treatment box 103. The output shaft of the control motor 106 is connected to the transmission shaft 107. The transmission shaft 107 is connected to the upper idler of the slime conveyor belt 105 through a collecting belt transmission member 108. The control motor 106 drives the slime conveyor belt 105 to run through the transmission shaft 107 and the collecting belt transmission member 108. The rotary collecting device is installed on the mounting frame 104. The rotary collecting device cooperates with the slime conveyor belt 105 to collect the slime in the water channel. The depth adjustment assembly is installed in front of the screening box 102. The depth adjustment assembly is used to adjust the height of the mounting frame 104.

[0034] The coal slime remaining on the inner belt of the mine belt conveyor will fall downward into the water channel excavated on the ground at the head of the belt. Most of the coal slime will flow with the water, but there will still be some coal slime deposited and adhered to the inner bottom surface of the water channel. When cleaning the coal slime, first start the control motor 106. The control motor 106 drives the coal slime conveyor belt 105 to run through the transmission shaft 107 and the collecting belt transmission part 108. The wheels inside the walking wheel bracket 101 move along the track 1, thereby driving the screening box 102, the treatment box 103 and the mounting frame 104 to move. When the front shovel plate 1041 extends into the water channel, the water in the water channel will pass through the through holes on the front shovel plate 1041, while the coal slime in the water is blocked by the front shovel plate 1041 to collect the coal slime in the water channel. Subsequently, the coal slime conveyor belt 105 conveys the coal slime in the water channel upward into the screening box 102. When the coal slime is sent onto the coal slime conveyor belt 105, the elastic partition outside the coal slime conveyor belt 105 will provide support for the coal slime to prevent the coal slime from sliding downward. After screening out the water in the coal slime, the coal slime will be sent into the treatment box 103 for recycling and treatment. When there is coal slime adhered to the inner bottom surface of the water channel, the mounting frame 104 is adjusted to swing downward through the depth adjustment component, so that the front end of the front shovel plate 1041 is flush with the inner bottom surface of the water channel, so that the coal slime adhered to the inner bottom surface of the water channel can be shoveled up and recycled during the movement of the front shovel plate 1041. After the control motor 106 is started, the rotating collecting device runs accordingly. During the operation of the rotating collecting device, the coal slime in the water channel is sent along the front shovel plate 1041 towards the coal slime conveyor belt 105, realizing the function of recycling the coal slime in the water channel.

[0035] Example 2: On the basis of Example 1, as Figures 3-7As shown in the figure, the rotary collecting device includes an L-shaped plate 1042, a toggle roller 2, an internal gear ring 2001, a rotating gear 201, a driven gear 202, a toggle belt transmission member 203, a fixing plate 204, a planetary gear 2041, a rotating shaft 205, a central gear 2051, and a chiseling assembly. The front end of the mounting frame 104 is fixedly connected with the L-shaped plate 1042. The fixing plate 204 is fixedly connected to the L-shaped plate 1042. The rotating shaft 205 is rotatably connected inside the L-shaped plate 1042. The rotating shaft 205 passes through the fixing plate 204 and is rotatably connected thereto. The toggle roller 2 is rotatably connected outside the fixing plate 204. The outer side of the toggle roller 2 is provided with a rectangular toggle plate extending outwards to send the slime towards the slime conveyor belt 105 during the rotation of the toggle roller 2. The internal gear ring 2001 is fixedly connected inside the toggle roller 2. The rotating gear 201 is fixedly connected to the lower idler of the slime conveyor belt 105. The driven gear 202 is rotatably connected to the L-shaped plate 1042. The rotating gear 201 meshes with the driven gear 202. The slime conveyor belt 105 can drive the driven gear 202 to rotate through the rotating gear 201. The driven gear 202 and the rotating shaft 205 are connected by the toggle belt transmission member 203. The driven gear 202 can drive the rotating shaft 205 to rotate through the toggle belt transmission member 203. The central gear 2051 is fixedly connected to the outside of the rotating shaft 205. The planetary gear 2041 is rotatably connected to the fixing plate 204. The central gear 2051 meshes with the planetary gear 2041. Both the central gear 2051 and the planetary gear 2041 are located inside the fixing plate 204. The planetary gear 2041 meshes with the internal gear ring 2001. When the rotating shaft 205 rotates, it drives the planetary gear 2041 and the internal gear ring 2001 to rotate through the central gear 2051. The internal gear ring 2001 drives the toggle roller 2 to rotate. The chiseling assembly is installed inside the toggle roller 2 and is used to chisel and break the large pieces of slime that are stuck together and then recycle them.

[0036] When the slime conveyor belt 105 rotates, it can drive the rotating gear 201 to rotate. The rotating gear 201 drives the rotating shaft 205 to rotate through the driven gear 202 and the toggle belt transmission member 203. When the rotating shaft 205 rotates, it can drive the planetary gear 2041 to rotate through the central gear 2051. When the planetary gear 2041 rotates, it can drive the toggle roller 2 to rotate through the internal gear ring 2001. When the toggle roller 2 rotates, it can send the slime in the water channel towards the front shovel plate 1041, and at the same time, it can also push the slime on the front shovel plate 1041 towards the slime conveyor belt 105. When the slime adheres to the bottom of the water channel, the chiseling assembly is started. The chiseling assembly chisels and breaks the slime adhering to the bottom of the water channel and then recycles it, improving the cleaning efficiency.

[0037] As Figures 5-7As shown, the chiseling assembly includes a movable chiseling plate 3, a rotating guide ring 301, a movable frame 302, a movable push ring 303, a buffer spring 304, an electric slider 305 and a swing push rod 306. The movable chiseling plate 3 is slidably connected in the toggle drum 2. The movable chiseling plate 3 is located in a rectangular toggle plate extending outward from the toggle drum 2. The rotating shaft 205 is fixedly connected with a rotating guide ring 301. The rotating shaft 205 is rotatably connected with the movable frame 302. The movable push ring 303 is slidably connected to the movable frame 302. A buffer spring 304 is provided between the movable push ring 303 and the movable frame 302. One end of the buffer spring 304 is fixed to the movable frame 302. The other end is fixed on the moving push ring 303. An electric guide rail is provided in the rotating guide ring 301. An electric slider 305 is installed in the electric guide rail in the rotating guide ring 301. After the electric guide rail is energized, the electric slider 305 is controlled to move. The electric slider 305 can push the buffer spring 304 and the moving frame 302 to slide along the rotating shaft 205 through the moving push ring 303. An annular slide groove is provided in the moving push ring 303. One end of the electric slider 305 is slidably connected to the annular slide groove on the moving push ring 303. A swing push rod 306 is rotatably connected to the moving frame 302, and the other end of the swing push rod 306 is rotatably connected to the moving chisel plate 3.

[0038] When there is a lot of coal slime adhering to the bottom surface of the water channel, the electric guide rail in the rotating guide ring 301 is energized to make the electric slider 305 move toward the moving frame 302. The electric slider 305 pushes the moving frame 302 to rotate along the rotating shaft 205 through the moving push ring 303 and the buffer spring 304. When the two moving frames 302 are close to each other, the moving chisel plate 3 can be pushed out from the rectangular toggle plate outside the toggle roller 2 by the swing push rod 306. As the toggle roller 2 rotates continuously, the moving chisel plate 3 rotates accordingly and contacts the coal slime adhering to the bottom surface of the water channel. 3 will be continuously rotated to break the coal slime, and because the buffer spring 304 is provided, a certain buffer effect is provided when the movable chisel plate 3 contacts the coal slime, which can reduce the damage of the movable chisel plate 3 in the process of chiseling the coal slime. After cleaning, the electric guide rail in the rotating guide ring 301 is reversely energized to make the electric slider 305 slide into the electric guide rail in the rotating guide ring 301 again, and at the same time drive the movable push ring 303, the buffer spring 304 and the movable frame 302 to move and reset. Driven by the swing push rod 306, the movable chisel plate 3 slides and resets along the paddle roller 2.

[0039] like Figure 3 and Figure 4As shown in the figure, the depth adjustment component includes a connecting plate 1043 and a lifting cylinder 109. The connecting plate 1043 is fixedly connected to the mounting frame 104. The top of the connecting plate 1043 is bent horizontally. The lifting cylinder 109 is installed at the front end of the screening box 102. The top of the output shaft of the lifting cylinder 109 contacts the connecting plate 1043. The lifting cylinder 109 can jack up the mounting frame 104 through the connecting plate 1043 to drive the mounting frame 104 and the front shovel plate 1041 to rise upward.

[0040] The more slime accumulates in the water channel near the mine belt head. During the cleaning process, it is necessary to continuously adjust the heights of the connecting plate 1043 and the mounting frame 104 through the lifting cylinder 109 to adjust the heights of the front shovel plate 1041 and the dialing roller 2, so as to clean the slime in the water channel layer by layer, clean the slime at different depths, improve the cleaning effect, and at the same time, it can also reduce the damage suffered by the equipment during the cleaning process and improve the service life.

[0041] Embodiment 3: On the basis of Embodiment 2, as Figure 8 and Figure 9 shown in the figure, it further includes a filtering component for filtering slime. The filtering component includes a swing sieve plate 4, a swing gear 401, a sliding plate 402, a lifting rod 403, a moving rack 4031, a cam 404, a connecting rod 405 and a sliding guide frame 406. The swing sieve plate 4 is rotatably connected in the screening box 102. The swing gear 401 is fixedly connected to the rotating shaft of the swing sieve plate 4. The sliding plate 402 is slidably connected in the screening box 102. The lifting rod 403 is fixedly connected to the sliding plate 402. The moving rack 4031 is arranged at the bottom of the lifting rod 403. The moving rack 4031 meshes with the swing gear 401. The cam 404 is rotatably connected outside the processing box 103. The cam 404 has no connection with the control motor 106. The cam 404 is controlled separately by additional power, and the cam 404 will not swing freely during the movement of the equipment. The sliding guide frame 406 is slidably connected outside the processing box 103. An inclined slideway is arranged in the sliding guide frame 406. The top of the lifting rod 403 is slidably connected in the sliding guide frame 406. The eccentric part of the cam 404 is rotatably connected to the connecting rod 405. The other end of the connecting rod 405 is fixedly connected to the sliding guide frame 406. The cam 404 drives the sliding guide frame 406 to slide reciprocally along the processing box 103 through the connecting rod 405.

[0042] After the coal slime conveyor belt 105 conveys the coal slime into the screening box 102, the coal slime will fall on the swinging screen plate 4, and the swinging screen plate 4 will screen the coal slime and the water on its surface. When there is more coal slime on the swinging screen plate 4, the control cam 404 will rotate one circle. When the cam 404 rotates, the sliding guide frame 406 will be driven to slide back and forth along the processing box 103 through the connecting rod 405. When the sliding guide frame 406 slides in the direction close to the cam 404, the lifting rod 403 will slide downward along the inclined slideway in the sliding guide frame 406, and at the same time drive the sliding plate 402 to slide downward along the screening box 102. When the lifting rod 403 descends, it can drive the moving rack 4031 to descend, and the moving rack The descent of bar 4031 will drive the swing gear 401 to rotate clockwise, and at the same time drive the swing screen plate 4 to rotate clockwise, so as to pour the coal slime on the swing screen plate 4 into the processing box 103. When the sliding guide frame 406 slides in the direction away from the cam 404, the lifting rod 403 will rise along the inclined slideway in the sliding guide frame 406, and at the same time drive the sliding plate 402 and the movable rack 4031 to rise. When the movable rack 4031 rises, it can drive the swing gear 401 to rotate counterclockwise, and the swing screen plate 4 swings downward counterclockwise to reset, and re-receives the coal slime that has not been sent into the screening box 102, thereby realizing the function of screening out water in the coal slime and sending the coal slime into the processing box 103.

[0044] When the coal slime is sent to the swinging screen plate 4, some water will enter the screening box 102, and the water in the screening box 102 will flow into the water storage frame 501 through the outlet pipe 5, and finally the water in the water storage frame 501 will be sprayed outward through the water spray port 502 to rinse the outside of the moving drum 2.

[0045] like Figure 10 and Figure 11As shown in the figure, it further includes a grinding mechanism for grinding slime. The grinding mechanism includes a collecting plate 6, a rotating grinding frame 601, a first bevel gear transmission group 602, a grinding runner 603, a vibrating sieve plate 604, a wedge block 605 and a cylindrical rod 606. A collecting plate 6 is installed in the storage bin. The collecting plate 6 is arc-shaped and concave downward. A rotating grinding frame 601 is rotatably connected in the processing box 103. A grinding runner 603 is rotatably connected to the rotating grinding frame 601. The rotating grinding frame 601 is connected to the transmission shaft 107 through the first bevel gear transmission group 602. The transmission shaft 107 drives the rotating grinding frame 601 to rotate through the first bevel gear transmission group 602, and the grinding runner 603 rotates accordingly to grind the slime. A vibrating sieve plate 604 is slidably connected in the processing box 103. A wedge block 605 is fixedly connected to the bottom of the vibrating sieve plate 604. A cylindrical rod 606 is fixedly connected to the outside of the rotating grinding frame 601. The cylindrical rod 606 cooperates with the wedge block 605. As the rotating grinding frame 601 rotates, the cylindrical rod 606 pushes the vibrating sieve plate 604 to slide upward through the wedge block 605, so that the vibrating sieve plate 604 vibrates up and down to screen the slime.

[0046] When the slime is put into the processing box 103, the slime will fall on the collecting plate 6, and the slime will slide down along the inner arc surface of the collecting plate 6. The control motor 106 can drive the first bevel gear transmission group 602 through the transmission shaft 107 to drive the rotating grinding frame 601 to rotate, and the grinding runner 603 rotates accordingly. Finally, under the cooperation of the processing box 103 and the grinding runner 603, the slime entering the processing box 103 will be ground. The ground slime falls on the vibrating sieve plate 604. During the rotation of the rotating grinding frame 601, the cylindrical rod 606 will contact the inclined surface of the wedge block 605. When the cylindrical rod 606 continues to rotate with the rotating grinding frame 601, the cylindrical rod 606 will push the vibrating sieve plate 604 to slide upward through the wedge block 605. When the cylindrical rod 606 is separated from the wedge block 605, the vibrating sieve plate 604 will slide downward to reset, so that the vibrating sieve plate 604 vibrates up and down to screen the ground slime.

[0047] As Figure 11 and Figure 12As shown in the figure, it further includes a drying mechanism for drying coal slime. The drying mechanism includes a second bevel gear transmission group 607, a drying box 7, a connecting shaft 701, a spur gear transmission group 702, a reciprocating lead screw 703 and a moving tooth plate 704. The drying box 7 is fixedly connected to the bottoms of the screening box 102 and the treatment box 103. The connecting shaft 701 is rotatably connected to the bottom of the treatment box 103. The rotating grinding frame 601 is connected to the connecting shaft 701 through the second bevel gear transmission group 607. The rotating grinding frame 601 drives the connecting shaft 701 to rotate through the second bevel gear transmission group 607. The reciprocating lead screw 703 is rotatably connected inside the drying box 7. The reciprocating lead screw 703 is connected to the connecting shaft 701 through the spur gear transmission group 702. The moving tooth plate 704 is slidably connected inside the drying box 7. The moving tooth plate 704 is threadedly connected to the reciprocating lead screw 703. When the reciprocating lead screw 703 rotates, the moving tooth plate 704 can reciprocate along the drying box 7 to flatten the coal slime inside the drying box 7 and improve the drying efficiency.

[0048] When the coal slime is ground and screened, it will fall downward into the drying box 7. When the rotating grinding frame 601 rotates, it drives the connecting shaft 701 to rotate through the second bevel gear transmission group 607. The connecting shaft 701 drives the reciprocating lead screw 703 to rotate through the bevel gear transmission group. When the reciprocating lead screw 703 rotates, it drives the moving tooth plate 704 to reciprocate inside the drying box 7. During the movement of the moving tooth plate 704, it will push away the coal slime falling into the drying box 7 to prevent the coal slime from piling up and improve the drying effect.
