Description

Technical Field

[0001] This invention belongs to the field of dust removal technology for continuous mining machines, specifically a dust removal device for continuous mining machines. Background Technology

[0002] Continuous mining machines are a new type of equipment that integrates tunneling, mining, and material handling. They are commonly used in coal mining. During coal mining, continuous mining machines can improve mining efficiency and reduce labor costs. However, the mining process generates a large amount of coal-containing dust. This dust not only pollutes the air but also obstructs the visibility of miners and harms their health. Therefore, continuous mining machines need to have dust removal capabilities.

[0003] A patent with publication number CN210768763U discloses a dust removal device for a continuous coal mining machine, including a base installed on the continuous coal mining machine body, several grooves opened on the base and spaced apart along the length of the base, slide seats slidably connected in each groove, a nozzle at one end of each water outlet pipe and a soft water pipe connected to the other end, each soft water pipe being connected through a water distribution box, and a water supply pipe being connected to the side wall of the water distribution box; a servo motor is provided at one end of the base, and the motor shaft of the servo motor is connected to each central shaft through a transmission component. This utility model has the effect of improving the flexibility of the dust removal device.

[0004] The above-mentioned method of dust removal during continuous mining machine operation is problematic because the dust generated in coal mines is quite large. Complete dust removal by spraying would produce a lot of water in the coal mine, which would hinder the movement of workers and other equipment, waste a lot of water, and pollute the mine environment. Moreover, the sprayed water mist would still be inhaled by workers, causing them harm, and the water mist would also obstruct their vision, affecting the coal mining efficiency of the continuous mining machine.

[0009] Preferably, the dust collection device includes a rotating ring rotatably connected to a plurality of dust collection ports, with through openings on both sides of the rotating ring. A first motor is fixedly connected to one side of the rotating ring inside the coal mining platform. A gear is fixedly connected to the output end of the first motor. The gear meshes with one side of the rotating ring. A dust collection groove is provided on one side of the coal mining platform. The dust collection groove is fixedly connected to a dust collection pipe.

[0010] Preferably, a plurality of guardrails are fixedly connected to one side of the conveyor belt, and the plurality of guardrails are slidably connected to the conveyor box. The plurality of guardrails are used to transport coal blocks out of the coal mining platform.

[0011] Preferably, a rotating arm is rotatably connected to one side of the coal mining platform, a telescopic rod is rotatably connected to one side of the coal mining platform, the rotating arm is rotatably connected to the coal mining wheel, the telescopic rod is rotatably connected to the coal mining wheel, and a drive device for driving the coal mining wheel to rotate is provided on one side of the coal mining wheel.

[0012] Preferably, a filter plate is slidably connected inside the dust removal chamber, and a discharge port is opened on one side of the dust removal chamber. The filter plate is used to separate and transport coal blocks and coal dust out of the dust removal chamber.

[0013] Preferably, two sliding rods are fixedly connected to both sides of the dust removal chamber, and springs are sleeved on each of the sliding rods. One end of each spring is fixedly connected to the dust removal chamber, and the other end of each spring is fixedly connected to the filter plate. A driving device for driving the filter plate to move back and forth is provided on one side of the dust removal chamber.

[0014] Preferably, a discharge device is provided inside the dust removal chamber on the lower side of the filter plate. The discharge device includes a discharge trough opened on the lower side of the dust removal chamber, and a discharge hopper is fixedly connected to one side of the discharge trough.

[0015] Preferably, the discharge device includes two auger rods rotatably connected in the discharge trough, the two auger rods rotating to discharge viscous coal dust from the dust removal chamber.

[0017] The beneficial effects of this invention are as follows: 1. The dust removal device for a continuous mining machine of the present invention, by driving a dust collection device, draws coal dust from the air into the coal mining platform through a dust collection port, and then through a dust collection pipe into a dust removal chamber. Multiple dust collection ports collect airborne dust from multiple angles, drawing coal dust from the upper, lower, and front sides of the coal mining platform into the dust removal chamber. The dust is then settled by spray nozzles and water inlets within the dust removal chamber. This method effectively draws as much coal dust generated during coal mining as possible into the dust removal chamber for dust removal, reducing coal dust pollution of the working environment, reducing the amount of coal dust inhaled by workers, improving the workers' visibility during coal mining, effectively improving work efficiency, ensuring the health of workers, and reducing environmental pollution.

[0018] 2. The dust removal device for a continuous mining machine according to the present invention drives a first motor to rotate, causing a rotating ring to rotate so that the upper passage completely overlaps with the upper dust suction port or opens a large gap. At this time, the lower passage does not overlap with the lower dust suction port, causing the rotating ring to block the lower dust suction port or leave only a small gap. This increases the airflow of the upper dust suction port and reduces the airflow of the lower dust suction port. In this way, while maintaining the same dust suction airflow, a better dust removal effect can be achieved. At this time, the front dust suction port still maintains suction power, so better dust removal can be achieved without adding a new dust collector. When taking coal blocks from the lower side, the first motor is driven to rotate the rotating ring to close and reduce the airflow of the upper dust suction port, while increasing the airflow of the lower dust suction port, which can better remove coal dust from the air.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Example 1 like Figures 1 to 10 As shown in the embodiment of the present invention, a dust removal device for a continuous mining machine includes a coal mining platform 1. A coal mining wheel 7 is rotatably connected to one side of the coal mining platform 1. A conveyor box 10 is fixedly connected inside the coal mining platform 1. A conveyor belt 11 is rotatably connected inside the conveyor box 10. The conveyor belt 11 is used to transfer coal blocks out of the coal mining platform 1. A dust removal chamber 2 is fixedly connected inside the coal mining platform 1. A water inlet 3 is fixedly connected to one side of the dust removal chamber 2. A spray head 23 is provided on the upper side of the dust removal chamber 2. Two dust inlet suction pipes 4 are fixedly connected to one side of the dust removal chamber 2. Two dust collection devices are provided on one side of the coal mining platform 1. The dust collection devices include multiple dust suction ports 5 opened on one side of the coal mining platform 1. The multiple dust suction ports 5 are distributed in an upper, middle and lower manner. The multiple dust suction ports 5 are fixedly connected to the dust suction pipes 4. The multiple dust suction ports 5 are used to suck coal dust dispersed in the air into the dust removal chamber 2.

[0023] Specifically, during the dust removal process of the coal mining machine, the coal mining platform 1 is moved to the working area, and the coal mining wheel 7 is driven to rotate for coal mining. The mined coal blocks are transferred out of the coal mining platform 1 via the conveyor belt 11 for use. At this time, a large amount of coal dust will be generated and float in the air. It is necessary to drive the dust collection equipment to suck the coal dust in the air into the coal mining platform 1 through the dust collection port 5, and then into the dust collection chamber 2 through the dust collection pipe 4. The dust in the air is collected from multiple angles through multiple dust collection ports 5, and the coal dust on the upper side, lower side and front side of the coal mining platform 1 are all sucked into the dust collection chamber 2. Then, the coal dust in the dust collection chamber 2 is settled by the spray head 23 and water inlet 3 in the dust collection chamber 2. This can suck as much of the coal dust generated during coal mining into the dust collection chamber 2 for dust removal, reduce the occurrence of coal dust pollution in the working environment, reduce the degree of coal dust inhaled by workers, make the workers' working vision clearer during coal mining, effectively improve the work efficiency of workers, ensure the health of workers, and reduce environmental pollution.

[0024] like Figures 1 to 10 As shown, a collection bucket 8 is rotatably connected to the lower side of the coal mining platform 1. A notch is opened on one side of the collection bucket 8, and two rotating fans 9 are rotatably connected to one side of the collection bucket 8. Both rotating fans 9 are equipped with driving devices.

[0025] Specifically, when the coal is mined by the coal mining wheel 7, the mined coal will fall into the collection hopper 8. At this time, the rotating fan 9 is started to make the two rotating fans 9 rotate to discharge the coal blocks in the collection hopper 8 from the gap. The coal blocks discharged from the collection hopper 8 will fall onto the conveyor belt 11 and be transferred and used by the conveyor belt 11.

[0026] like Figures 1 to 10 As shown, the dust collection device includes a rotating ring 18 rotatably connected to multiple dust collection ports 5. Both sides of the rotating ring 18 have through-holes 19. A first motor 16 is fixedly connected to one side of the rotating ring 18 inside the coal mining platform 1. A gear 17 is fixedly connected to the output end of the first motor 16. The gear 17 meshes with one side of the rotating ring 18. A dust collection groove 20 is provided on one side of the coal mining platform 1. The dust collection groove 20 is fixedly connected to the dust collection pipe 4.

[0027] Specifically, the openings 19 on both sides of the rotating ring 18 are asymmetrical. That is, when the upper dust suction port 5 is completely aligned with the upper opening 19, the lower dust suction port 5 is completely closed with the lower opening 19. When collecting coal dust through the dust suction port 5, when the coal mining wheel 7 picks up the upper coal block, the first motor 16 is driven to rotate, causing the rotating ring 18 to rotate so that the upper opening 19 is completely aligned with the upper dust suction port 5 or opens a large gap. At this time, the lower opening 19 is not aligned with the lower dust suction port 5, causing the rotating ring 18 to block the lower dust suction port 5 or... By leaving only a small gap, the airflow of the upper suction port 5 can be increased while the airflow of the lower suction port 5 can be reduced. This allows for better dust collection and removal while maintaining the same suction power. The front suction port 5 still maintains suction power, allowing for better dust collection without adding a new vacuum cleaner. When removing coal blocks from the lower side, the first motor 16 is driven to rotate the rotating ring 18 to close and reduce the airflow of the upper suction port 5, while increasing the airflow of the lower suction port 5 to better remove coal dust from the surrounding air.

[0028] like Figures 1 to 10 As shown, multiple guardrails 12 are fixedly connected to one side of the conveyor belt 11. The multiple guardrails 12 are slidably connected to the conveyor box 10. The multiple guardrails 12 are used to transport coal blocks out of the coal mining platform 1.

[0029] Specifically, when conveying coal blocks, the multiple guardrails 12 on the conveyor belt 11 can better transfer the coal blocks out for use, preventing the coal blocks from rolling to the bottom of the conveyor belt 11 and generating new coal dust. Furthermore, the coal blocks attached to the conveyor belt 11 and the guardrails 12 can fall back into the conveyor box 10, preventing the coal dust and coal blocks attached to the conveyor belt 11 and the guardrails 12 from falling to the ground and forming new coal dust that flies in the air. This allows the coal dust and coal blocks attached to the conveyor belt 11 and the guardrails 12 to return to the conveyor belt 11 for conveying out.

[0030] like Figures 1 to 10 As shown, a rotating arm 6 is rotatably connected to one side of the coal mining platform 1, and a telescopic rod 13 is rotatably connected to one side of the coal mining platform 1. The rotating arm 6 is rotatably connected to the coal mining wheel 7, and the telescopic rod 13 is rotatably connected to the coal mining wheel 7. A drive device for driving the coal mining wheel 7 to rotate is provided on one side of the coal mining wheel 7.

[0031] Specifically, during coal mining, the telescopic rod 13 is activated to adjust the height of the coal mining wheel 7, allowing the coal mining wheel 7 to rotate via the rotating arm 6. When the telescopic rod 13 pushes the coal mining wheel 7 to rotate and collect coal from the upper side, it will cause the rotating arm 6 to rotate upward, triggering the first motor 16 to rotate the rotating ring 18, increasing the airflow at the upper dust suction port 5 to quickly remove coal dust from the upper air. When the telescopic rod 13 retracts and causes the coal mining wheel 7 to rotate and collect coal from the lower side, it will cause the rotating arm 6 to rotate downward, triggering the first motor 16 to rotate the rotating ring 18, increasing the airflow at the lower dust suction port 5 to quickly remove coal dust from the lower air. Thus, the height of the coal mining wheel 7 can be adjusted via the telescopic rod 13 to mine coal from both the upper and lower sides, and the first motor 16 is activated via the rotating arm 6 to control the suction power of the upper and lower dust suction ports 5.

[0032] like Figures 1 to 10 As shown, a filter plate 15 is slidably connected inside the dust removal chamber 2, and a discharge port 14 is opened on one side of the dust removal chamber 2. The filter plate 15 is used to separate and transport coal blocks and coal dust out of the dust removal chamber 2.

[0033] Specifically, when the dust suction port 5 is suctioning dust, larger coal pieces will fly into the dust suction port 5 and be sucked into the dust collection chamber 2. When the dust in the dust collection chamber 2 is settled by the water sprayed from the spray head 23, it will fall onto the filter plate 15. The larger coal pieces will remain on the filter plate 15 and be discharged from the dust collection chamber 2 through the discharge port 14 and flow to the conveyor belt 11 for transfer, while the smaller coal dust will flow through the filter plate 15 to other places for subsequent processing and collection.

[0034] like Figures 1 to 10 As shown, two sliding rods 21 are fixedly connected to both sides of the dust removal chamber 2. Springs 22 are sleeved on multiple sliding rods 21. One end of multiple springs 22 is fixedly connected to the dust removal chamber 2, and the other end of multiple springs 22 is fixedly connected to the filter plate 15. A drive device for driving the filter plate 15 to move back and forth is provided on one side inside the dust removal chamber 2.

[0035] Specifically, the driving device can be a drive motor that drives a cam to strike the filter plate 15, causing the filter plate 15 to move back and forth at high speed. When the coal block falls onto the filter plate 15, the drive motor is started to make the cam rotate and strike the filter plate 15. After being struck, the filter plate 15 moves back and forth on the sliding rod 21, cyclically compressing the springs 22 on both sides, causing the filter plate 15 to move back and forth and generate vibration, so that the coal dust can pass smoothly through the filter holes on the filter plate 15, separating and collecting the coal block from the coal dust, so that the coal block will not block the filter plate 15 and can be smoothly discharged from the dust collection chamber 2 along the inclined direction of the filter plate 15 for collection and use.

[0036] Example 2 like Figures 1 to 10 As shown in Example 1, another embodiment of the present invention is as follows: The dust collection chamber 2 is equipped with a discharge device located below the filter plate 15. The discharge device includes a discharge trough 25 located below the dust collection chamber 2, and a discharge hopper 24 is fixedly connected to one side of the discharge trough 25.

[0037] Specifically, when the settled coal dust is discharged, the coal dust is sucked into the dust removal chamber 2 by the dust suction port 5. After passing through the spray head 23 in the dust removal chamber 2 to settle the coal dust, the settled coal dust will fall into the discharge trough 25 under the filter plate 15 after being separated by the filter plate 15, and will be discharged from the side of the discharge hopper 24 to the dust removal chamber 2 for subsequent processing.

[0038] like Figures 1 to 10 As shown, the discharge device includes two auger rods 26 rotatably connected in the discharge trough 25. The two auger rods 26 rotate to discharge viscous coal dust from the dust removal chamber 2.

[0039] Specifically, when discharging the settled coal dust, rotating the two auger rods 26 can discharge the coal dust in the discharge trough 25 from the discharge hopper 24. Furthermore, the cooperation of the two auger rods 26 can agitate and crush the coal dust, preventing the settled coal dust from solidifying and becoming difficult to discharge from the dust removal chamber 2.

[0040] like Figures 1 to 10 As shown, a second motor 28 is rotatably fixed to one side of the auger rod 26 inside the dust removal chamber 2. A transmission wheel 27 is fixed to one side of each of the two auger rods 26. The two transmission wheels 27 are connected by a transmission belt 29. The second motor 28 is fixed to the corresponding transmission wheel 27.

[0041] Specifically, when discharging the settled coal dust, the second motor 28 is started to rotate one drive wheel 27, which in turn causes both drive wheels 27 to rotate via the drive belt 29, thereby causing both auger rods 26 to rotate simultaneously to discharge and collect the settled coal dust for use.

[0042] Working principle: During the dust removal process of the coal mining machine, the coal mining platform 1 is moved to the working area, and the coal mining wheel 7 is driven to rotate to mine coal. The mined coal blocks are transferred out of the coal mining platform 1 via the conveyor belt 11 for use. At this time, a large amount of coal dust will be generated and float in the air. It is necessary to drive the dust collection equipment to suck the coal dust in the air into the coal mining platform 1 through the dust collection port 5, and then into the dust collection chamber 2 through the dust collection pipe 4. The dust in the air is collected from multiple angles through multiple dust collection ports 5, and the coal dust on the upper side, lower side and front side of the coal mining platform 1 are sucked into the dust collection chamber 2. Then, the coal dust in the dust collection chamber 2 is settled by the spray head 23 and the water inlet 3. This allows coal dust generated during coal mining to be sucked into the dust removal chamber 2 for dust removal, reducing the occurrence of coal dust pollution in the working environment, reducing the degree of coal dust inhaled by workers, making the workers' working vision clearer, effectively improving the workers' work efficiency, ensuring the workers' health, and reducing environmental pollution; when coal is mined by the coal mining wheel 7, the mined coal will fall into the collection hopper 8. At this time, the rotating fan 9 is started to make the two rotating fans 9 rotate to discharge the coal blocks in the collection hopper 8 from the gap in the collection hopper 8. The coal blocks discharged from the collection hopper 8 will fall onto the conveyor belt 11 and be transported and used by the conveyor belt 11; When collecting coal dust through the suction port 5, since the passages 19 on both sides of the rotating ring 18 are staggered, when the coal mining wheel 7 picks up the upper coal block, the first motor 16 is driven to rotate, causing the rotating ring 18 to rotate so that the upper passage 19 completely overlaps with the upper suction port 5 or opens a large gap. At this time, the lower passage 19 does not overlap with the lower suction port 5, causing the rotating ring 18 to block the lower suction port 5 or leave only a small gap. This increases the airflow of the upper suction port 5 and reduces the airflow of the lower suction port 5. In this way, while maintaining the same suction airflow, a better dust collection effect and dust removal can be achieved. At this time, the front suction port 5 still maintains suction power, so that no new vacuum cleaner is needed. In order to improve dust collection, when taking coal blocks from the lower side, the first motor 16 drives the rotating ring 18 to rotate and close, reducing the airflow of the upper dust suction port 5 and increasing the airflow of the lower dust suction port 5 to better remove coal dust from the air. When conveying coal blocks, the multiple guardrails 12 on the conveyor belt 11 can better transfer the coal blocks out for use, and the coal blocks attached to the conveyor belt 11 and the guardrails 12 can fall back into the conveyor box 10 and return to the conveyor belt 11 for conveying out again. When mining coal, the telescopic rod 13 is activated to adjust the height of the mining wheel 7, so that the mining wheel 7 can be rotated through the rotating arm 6, thereby adjusting the height of the mining wheel 7 to mine coal from the upper and lower sides of the coal mine. When the dust suction port 5 is used, larger coal chunks may fly into it and be sucked into the dust collection chamber 2. After the dust in the dust collection chamber 2 is settled by the water sprayed from the spray head 23, it falls onto the filter plate 15. Larger coal chunks remain on the filter plate 15 and are discharged from the dust collection chamber 2 through the discharge port 14, flowing to the conveyor belt 11 for transfer. Smaller coal dust passes through the filter plate 15 and flows to other locations for further processing and collection. When coal chunks fall onto the filter plate 15, the reciprocating equipment is activated to move the filter plate 15 back and forth, allowing coal dust that can pass through the filter plate 15 to pass smoothly without clogging it. 15. The dust is discharged from the dust collection bin 2 at an inclined direction for collection and use; when the settled coal dust is discharged, the settled coal dust will fall into the discharge trough 25 and will be discharged from the side of the discharge hopper 24 to the dust collection bin 2 for further processing; rotating the two auger rods 26 can discharge the coal dust in the discharge trough 25 from the discharge hopper 24, and the cooperation of the two auger rods 26 can agitate and crush the coal dust to prevent the settled coal dust from solidifying and being difficult to discharge from the dust collection bin 2; starting the second motor 28 makes one drive wheel 27 rotate, which can make both drive wheels 27 rotate through the drive belt 29, so that the two auger rods 26 can rotate simultaneously to discharge the settled coal dust for collection and use.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
