Description

Technical Field

[0001] This utility model relates to dust suppression equipment for coal mining, specifically a dust suppression device for use in coal mining environments. Background Technology

[0002] Coal mining underground generates large amounts of coal dust and particulate matter, making dust control in coal mines particularly important. Traditional dust control methods involve manual hand-held water sprayers, which are inefficient and ineffective. Existing coal mine dust suppression devices typically consist of multiple spray nozzles installed on the inner walls of the tunnels to spray water mist for dust reduction. However, the complex environment within tunnels and existing dust suppression devices suffer from structural instability, inconvenient height adjustment, and poor support stability. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model aims to provide a dust suppression device for coal mining environment. This device has good dust suppression effect, can be height-adaptive to the height of the roadway, and can also effectively support the base, significantly improving structural stability.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A dust suppression device for coal mining environments includes a base, a water supply plate, and spray heads. Lifting plates are vertically fixed to both sides of the water supply plate, and each lifting plate is mounted on a corresponding base via a lifting drive mechanism. The spray heads are installed on the bottom of the water supply plate and on the opposite side walls of the two lifting plates, and are connected to an external water source via a water supply assembly. Wheels are installed under the base, and support mechanisms are symmetrically installed on both sides of the base. Each support mechanism includes outriggers and a linkage drive assembly. The linkage drive assembly is mounted on the side wall of the base, and the outriggers are connected to the moving parts of the linkage drive assembly.

[0006] Preferably, the lifting drive mechanism includes a slide rod and a screw rod vertically disposed above the base. The slide rod is fixed to the top of the base, and the screw rod is rotatably mounted on the base and is powered by a motor in the internal cavity of the base. A limit sliding hole and a threaded hole are vertically formed in the lifting plate. The slide rod is vertically slidably inserted into the limit sliding hole, and the screw rod is threadedly sleeved in the threaded hole.

[0007] Preferably, a limiting block is fixed at the upper end of the slide rod, the limiting block is slidably engaged with the limiting slide hole, and the diameter of the limiting block is larger than the lower opening diameter of the limiting slide hole.

[0008] Preferably, the water supply assembly includes a water supply pipe, a through-hole, a first water supply channel, and a second water supply channel. The through-hole is vertically inserted into the lifting plate with its opening facing downwards. The first water supply channel is located inside the lifting plate, and the second water supply channel is located inside the water supply plate. The lower end of the second water supply channel is connected to the first water supply channel. The first water supply channel is connected to a spray head on the lifting plate, and the second water supply channel is also connected to a spray head on the water supply plate. The water supply pipe is vertically installed on the base. The lower end of the water supply pipe is connected to an external water source, and the upper end is slidably inserted into the through-hole. The upper end of the through-hole is connected to the upper end of the first water supply channel.

[0009] Preferably, a sealing ring is provided at the upper opening of the water supply pipe, and the sealing ring cooperates with the inner wall of the pipe hole.

[0010] Preferably, the linkage drive assembly includes a telescopic cylinder and a first and second linkage arranged parallel to each other vertically. One end of the first and second linkages is rotatably connected to the side wall of the base via corresponding first rotating shafts, and the other end is rotatably connected to the support leg via corresponding second rotating shafts. The tail of the telescopic cylinder is rotatably connected to the first rotating shaft corresponding to the second linkage, and the piston rod end of the telescopic cylinder is rotatably connected to the second rotating shaft corresponding to the first linkage.

[0011] Preferably, the outrigger includes a support rod and a foot, and the two connecting rods and the piston rod of the telescopic cylinder are rotatably connected to the vertically arranged support rod through a second rotating shaft; the foot is installed at the lower end of the support rod.

[0012] Preferably, the water supply board adopts an arc-shaped structure that matches the top of the coal mine roadway.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. When the dust suppression height needs to be adjusted, the screw is rotated by the motor. Under the sliding limit action of the slide rod and the limiting slide hole, the threaded hole in the lifting plate cooperates with the screw, so that the lifting plates on both sides can drive the water supply plate to move up and down, thereby enabling the device to adapt to the dust suppression use in roadways of different heights.

[0015] 2. A limiting block is fixedly provided at the upper end of the slide rod, and the limiting block slides in a sliding fit with the limiting slide hole. This application uses the limiting block fixed at the upper end of the slide rod to limit the upward displacement height of the slide rod, preventing the lifting plate from detaching from the slide rod and improving the stability of the device.

[0016] 3. In this application, the external water source enters the through-hole through a water supply pipe, and then sequentially enters the first and second water supply channels. The water mist is then sprayed outwards from the spray heads installed in the two water supply channels, effectively reducing dust. Furthermore, because the water supply pipe and the through-hole are vertically slidably fitted together, when the lifting plate is moved up and down to adjust the height, the water supply pipe only changes its vertical insertion position within the through-hole, without affecting the water supply effect, thus ensuring water supply stability.

[0017] 4. When this device needs to move within a tunnel, the telescopic cylinders on both sides of the base extend, causing the two connecting rods to swing upwards around the first pivot, thereby moving the outriggers upwards and retracting them. The device can then be moved and transported within the tunnel using the wheels beneath the base. When dust suppression operations are required in the mining area, the telescopic cylinders retract, causing the two connecting rods to swing downwards. The outriggers' support feet rest on the ground, lifting the base and causing the wheels to leave the ground. This allows for rapid extension and retraction of the outriggers, providing stable support and improving operational efficiency. Attached Figure Description

[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of application of this utility model.

[0022] like Figure 1-3 As shown, this utility model proposes a dust suppression device for coal mining environments, including a base 6, a water supply plate 1, and a spray head 3. The water supply plate 1 can adopt an arc-shaped structure that matches the top of the roadway. Lifting plates 2 are vertically fixed to both sides of the water supply plate 1, and the lifting plates 2 are mounted on the corresponding base 6 via a lifting drive mechanism. The lifting drive mechanism includes a sliding rod 71 and a screw 72 vertically mounted above the base 6. The lower end of the sliding rod 71 is fixed to the top of the base 6, and the lower end of the screw 72 is rotatably mounted on the base 6 and powered by a motor 721 in the internal cavity 60 of the base 6. A limiting sliding hole 21 and a threaded hole 24 are vertically formed inside the lifting plate 2. The sliding rod 71 is vertically slidably inserted into the limiting sliding hole 21, and the screw 72 is threadedly sleeved in the threaded hole 24.

[0023] When the dust suppression height needs to be adjusted, the motor 721 drives the screw 72 to rotate. Under the sliding limit action of the slide rod 71 and the limiting slide hole 21, the threaded hole 24 in the lifting plate 2 cooperates with the screw 72, so that the lifting plates 2 on both sides can drive the water supply plate 1 to move up and down, thereby enabling the device to adapt to the dust suppression use in roadways of different heights.

[0024] In addition, a limiting block 711 is fixedly provided at the upper end of the slide rod 71. The limiting block 711 is slidably engaged with the limiting sliding hole 21, and the diameter of the limiting block 711 is larger than the lower opening diameter of the limiting sliding hole 21. By using the limiting block 711 fixed at the upper end of the slide rod 71, this application can limit the upward displacement height of the slide rod 71, prevent the lifting plate 2 from disengaging from the slide rod 71, and improve the stability of the device.

[0025] Sprinkler heads 3 are installed on the bottom of the water supply plate 1 and on the opposite side walls of the two lifting plates 2. The sprinkler heads 3 are connected to an external water source through the water supply assembly. Specifically, the water supply assembly includes a water supply pipe 5, a through-hole 22, a first water supply channel 23, and a second water supply channel 11. The through-hole 22 is vertically opened downwards in the lifting plate 2. The first water supply channel 23 is vertically located inside the lifting plate 2, and the second water supply channel 11 is located inside the water supply plate 1. The two ends of the second water supply channel 11 in the water supply plate 1 are respectively connected to the first water supply channel 23 in the two lifting plates 2. The first water supply channel 23 is connected to the sprinkler heads 3 on the lifting plate 2, and the second water supply channel 11 is connected to the sprinkler heads 3 on the water supply plate 1. The water supply pipe 5 is vertically installed on the base 6. The inlet at the lower end of the water supply pipe 5 is connected to an external water source, and the upper end is slidably inserted into the through-hole 22. The upper end of the through-hole 22 is connected to the upper end of the first water supply channel 23. A sealing ring 51 is provided at the upper opening of the water supply pipe 5. The sealing ring 51 fits with the inner wall of the through hole 22. The sealing ring 51 can improve the sealing between the water supply pipe 5 and the through hole 22 and prevent water leakage.

[0026] The external water source enters the through-hole 22 through the water supply pipe 5, and then sequentially enters the first water supply channel 23 and the second water supply channel 11. Water mist is then sprayed outwards through the spray heads 3 installed on the two water supply channels, effectively reducing dust. Furthermore, since the water supply pipe 5 and the through-hole 22 are vertically slidably fitted together, when the lifting plate 2 moves up and down to adjust its height, the water supply pipe 5 only changes its vertical insertion position within the through-hole 22, without affecting the water supply effect, thus ensuring water supply stability.

[0027] A traveling wheel 61 is installed below the base 6. Support mechanisms 4 are symmetrically installed on both sides of the base 6. Each support mechanism 4 includes a support leg 44 and a linkage drive assembly. The linkage drive assembly is installed on the side wall of the base 6, and the support leg 44 is connected to the moving part of the linkage drive assembly. Specifically, the linkage drive assembly includes a telescopic cylinder 43 and a first connecting rod 41 and a second connecting rod 42 arranged parallel to each other vertically. One end of the first connecting rod 41 and the second connecting rod 42 are rotatably connected to the side wall of the base 6 via corresponding first rotating shafts, and the other end is rotatably connected to the support leg 44 via corresponding second rotating shafts. The tail of the telescopic cylinder 43 is rotatably connected to the first rotating shaft corresponding to the second connecting rod 42, and the piston rod end of the telescopic cylinder 43 is rotatably connected to the second rotating shaft corresponding to the first connecting rod 41. The support leg 44 includes a support rod 441 and a foot 442. Both connecting rods and the piston rod of the telescopic cylinder 43 are rotatably connected to the vertically arranged support rod 441 via second rotating shafts; the foot 442 is rotatably installed at the lower end of the support rod 441. In practice, the telescopic cylinder 43 can be a hydraulic cylinder structure.

[0028] When the device needs to move within a tunnel, the telescopic cylinders 43 on both sides of the base 6 extend, causing the two connecting rods to swing upwards around the first pivot, thereby moving the outriggers 44 upwards and retracting them. The traveling wheels 61 under the base 6 then allow the device to move and transport within the tunnel. When dust suppression is required in the mining area, the telescopic cylinders 43 retract, causing the two connecting rods to swing downwards. The support feet 442 of the outriggers 44 support the ground and lift the base 6, causing the traveling wheels 61 to leave the ground. This allows the device to quickly extend and retract the outriggers 44, providing stable support and improving operational efficiency.

[0029] When using this utility model, after moving the device to the mining area using the walking wheels 61, first control the telescopic cylinders 43 on both sides of the base 6 to retract, and then use the support legs 44 to stably support the device; then start the motor 721 to drive the screw 72 to rotate, and adjust the height of the lifting plate 2 and the water supply plate 1 according to the height of the roadway; connect the external water source to the water inlet below the water supply pipe 5, and spray uniform water mist outward through the spray head 3, thereby effectively suppressing dust in the roadway.
