[0019] S3. Dust collection and dust monitoring: Turn on the fan to draw outside air into the cylindrical barrel, push the block downward, open the exhaust holes, and separate the dust and drop it onto the ash falling inclined plate. The amount of dust in the mine is monitored by the pressure and rotation of the ash falling inclined plate. Finally, the dust falls into the ash storage box.

[0020] S4. Water mist dust removal: Turn on the water pump and let water flow into the rotating drum, so that the water is sprayed out from the end of the output drum into the mine environment for storage, and then turn on the drive motor to drive the rotating drum to rotate, so that the rotating drum rotates continuously to increase the range of water mist spraying.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1) During operation, the output cylinders are evenly installed on the circumferential outer wall of the rotating cylinder. Driven by the water pump, water is sprayed out through the output cylinders to form water mist, which helps to settle the dust. When the fan is turned on, the air in the mine is driven to enter the cylindrical cylinder through the large air inlet holes, and finally the dust falls into the ash storage box for storage. The two methods are used to remove dust from the mine and improve the dust removal effect.

[0023] 2) During operation, the output cylinders are evenly installed on the circumferential outer wall of the rotating cylinder, and one end of the rotating cylinder is connected to the output shaft of the driving motor. Driven by the driving motor, the rotating cylinder rotates continuously, and the output cylinders on the rotating cylinder move along the circumference of the rotating cylinder, so that the water mist spraying positions at the output cylinders increase, and the water mist spraying range is expanded, thereby improving the dust removal effect of the mine;

[0024] 3) During operation, air enters the square box through the arrangement and falls onto the ash falling inclined plate. Under the pressure of the dust, the ash falling inclined plate rotates downward and opens, causing the conductive slider to move upward. The greater the amount of dust, the smaller the resistance value of the sliding rheostat connected to the drive motor circuit, which increases the speed of the driving motor driving the rotating drum, and the centrifugal force on the water in the rotating drum, which increases the amount and density of water mist sprayed. The amount and density of water mist sprayed are adapted to the amount of dust in the mine and are adaptively adjusted to ensure the dust removal effect.

[0025] 4) During operation, the top of the block is set into a hemispherical shape, so that the block closes the bottom of the cylindrical tube. When the air in the mine enters the cylindrical tube, it pushes the block downward to open the exhaust hole to facilitate air discharge. The block can buffer the air and make the dust fall, which is convenient for subsequent detection of the dust amount in the mine and convenient for dust collection.

[0026] 5) During operation, an arc-shaped baffle is provided on the outside of the rotating cylinder, and the arc-shaped baffle can close part of the end of the output cylinder. When the arc-shaped baffle is rotated and adjusted, the position of the output cylinder that can spray water mist can be adjusted, thereby adjusting the spraying direction of the water mist. At the same time, the end face of the suction cup contacts the side wall of the limiting swivel. When the block moves downward, the piston is pulled downward, so that the suction cup and the limiting swivel are fixed by negative pressure adsorption, thereby facilitating the position fixation of the arc-shaped baffle.

A direction adjustment assembly 4 is provided on the outside of the rotating cylinder 301. The direction adjustment assembly 4 is used to control the spray direction. A dust collection processing assembly 5 is installed on the support plate 2 provided with the horizontal pipe 304. The dust collection processing assembly 5 is used to absorb dust and adjust the dust amount Monitor and fix the direction adjustment component 4. The nozzle part 302 includes an output cylinder 3021 evenly installed on the circumferential outer wall of the rotating cylinder 301. The output cylinder 3021 is connected to the inner cavity of the rotating cylinder 301. An impact plate 3022 is provided at the end of the output cylinder 3021. The surface of the impact plate 3022 away from the rotating cylinder 301 is arranged in an arc shape. Atomization holes 3023 are evenly opened on the impact plate 3022. The output cylinder 3021 is evenly installed on the circumferential outer wall of the rotating cylinder 301. At the same time, one end of the rotating cylinder 301 is connected to the output shaft of the driving motor 303. Under the drive of the driving motor 303, the rotating cylinder 301 rotates continuously, and the output cylinder 3021 on the rotating cylinder 301 moves circumferentially along the rotating cylinder 301, so that the water mist spraying positions at the output cylinder 3021 increase, the water mist spraying range is increased, and the dust removal effect of the mine is improved.

[0041] The direction adjustment component 4 includes a limiting ring groove 401 symmetrically opened on the outer wall of both ends of the rotating cylinder 301, and a limiting swivel 402 is rotatably installed on the inner side of the limiting ring groove 401. An arc-shaped baffle 403 is provided on the outer side of the rotating cylinder 301. A connecting rod 404 is installed between the arc-shaped baffle 403 and the limiting swivel 402. The arc-shaped surface of the impact plate 3022 is tightly attached to the inner wall of the arc-shaped baffle 403. The arc-shaped baffle 403 is used to close the output cylinder 3021 in part.

[0042] The dust collection and processing assembly 5 includes a square box 501 fixedly mounted on one side of one of the support plates 2, a cylindrical tube 502 is mounted on the top of the square box 501, and large air intake holes 503 for the air in the mine are opened at equal angles on the outer wall of the cylindrical tube 502, a fan 504 is mounted inside the cylindrical tube 502, a dust buffer 505 is arranged on the top of the square box 501, a dust quantity monitoring component 506 is arranged in the middle of the square box 501, and an ash storage box 507 for storing dust is mounted on the bottom of the square box 501, and the output tube 3021 is evenly mounted on the circumferential outer wall of the rotating tube 301. Driven by the water pump, water is sprayed outward through the output tube 3021 to form water mist, thereby realizing dust sedimentation. Turning on the fan 504 can drive the air in the mine to enter the cylindrical tube 502 through the large air intake holes 503, and finally the dust falls into the ash storage box 507 for storage. The mine dust is removed in two ways, thereby improving the dust removal effect.

[0043] The dust-falling buffer 505 includes a block 5051 arranged at the top of the inner cavity of the square box 501. The top of the block 5051 is set to be hemispherical, and the horizontal cross-section of the square box 501 is square, and the horizontal cross-section of the cylindrical tube 502 is circular, so that the top of the block 5051 closes the bottom end of the cylindrical tube 502. The block 5051 is connected to a negative pressure fixing member 508 that fixes the arc baffle 403. Side baffles 5053 are symmetrically installed on both sides of the block 5051. The side baffles 5053 are tightly attached to the inner wall of the square box 501. Exhaust holes 5052 are evenly opened on both sides of the square box 501. The side baffles 5053 block the exhaust holes 5052. The top of the block 5051 is set to be hemispherical, so that the block 5 051 closes the bottom end of the cylindrical tube 502. When the air in the mine enters the cylindrical tube 502, it pushes the block 5051 to move downward, opening the exhaust hole 5052 to facilitate air discharge. The block 5051 can buffer the air, allowing dust to fall, facilitating subsequent detection of the amount of dust in the mine and facilitating dust collection. A slider 5054 is installed on the side of the side baffle 5053 away from the block 5051. The slider 5054 is slidably installed inside the slide groove 5055. The slide groove 5055 is opened on the inner wall of the square box 501. The bottom end of the slide groove 5055 is fixedly installed with a first spring 5056, and the bottom end of the first spring 5056 is fixedly connected to the inner bottom wall of the slide groove 5055.

[0044] The dust quantity monitoring component 506 includes dust falling inclined blocks 5061 symmetrically installed on the inner walls of both sides of the square box 501, the dust falling inclined blocks 5061 are located below the slide 5055, and the interior of the block 5051 is symmetrically provided with dust falling inclined plates 5062. The bottom ends of the two dust falling inclined plates 5062 are in contact with each other, and the tops of the two dust falling inclined plates 5062 are both installed with rotating shafts 5063. The rotating shafts 5063 are rotatably connected to the square box 501, and the two rotating shafts 5063 are respectively located below the two dust falling inclined blocks 5061. The two sides of the square box 501 are symmetrically provided with transverse rod grooves 5064, and the interior of the transverse rod grooves 5064 is laterally movable. There is a horizontal rod 5065, and a support block 5066 is installed at one end of the horizontal rod 5065 located inside the square box 501. The end of the support block 5066 contacts the lower surface of the ash falling inclined plate 5062. A second spring 5067 is installed on the side of the support block 5066 away from the ash falling inclined plate 5062. One end of the second spring 5067 is fixedly connected to the inner wall of the square box 501. An external plate 5068 is installed at one end of the horizontal rod 5065 located outside the square box 501. A moving rod 5069 is installed on the side where the two external plates 5068 are close to each other. The moving rod 5069 is located in the square box 501 away from the support plate 2, a longitudinal movement block 50611 is provided on the side of the square box 501 away from the support plate 2, and a connecting rod 50610 is symmetrically hingedly installed on the top of the longitudinal movement block 50611. The tops of the two connecting rods 50610 are hinged to the ends of the two moving rods 5069 respectively. A sliding rheostat 50612 is installed on one side of the square box 501, and a longitudinally sliding conductive slide 50613 is installed on the sliding rheostat 50612. The longitudinal movement block 50611 is fixedly connected to the conductive slide 50613. The drive motor 303 and the sliding rheostat 50612 are arranged in series, and there is a contact between the drive motor 303 and the sliding rheostat 50612. A power supply and a switch are arranged in series. Air enters the square box 501 and falls onto the ash-falling inclined plate 5062. Under the pressure of the dust, the ash-falling inclined plate 5062 rotates downward and opens, causing the conductive slider 50613 to move upward. The greater the amount of dust, the smaller the resistance value of the sliding rheostat 50612 connected to the circuit of the drive motor 303, which makes the drive motor 303 drive the rotating drum 301 at a higher speed, and the water in the rotating drum 301 is subjected to greater centrifugal force, which increases the water mist spraying amount and spraying density, so that the water mist spraying amount and spraying density are adapted to the amount of dust in the mine and are adaptively adjusted to ensure the dust removal effect.

[0045] The negative pressure fixing member 508 includes a longitudinal tube 5081 fixedly mounted on the top of the square box 501. The longitudinal tube 5081 is located on the side of the cylindrical cylinder 502 close to the rotating cylinder 301. The top of the longitudinal tube 5081 is installed with a transverse tube 5082. One end of the transverse tube 5082 is installed with a suction cup 5083. The end face of the suction cup 5083 is in close contact with the side wall of one of the limiting rotating rings 402. A piston 5084 is movably installed inside the longitudinal tube 5081. The bottom end of the piston 5084 is installed with a pull rod 5085. The bottom end of the pull rod 5085 is fixedly connected to the stopper 5051. The rotating cylinder An arc-shaped baffle 403 is provided on the outside of 301, and the arc-shaped baffle 403 can close part of the end of the output tube 3021. When the arc-shaped baffle 403 is rotated and adjusted, the position of the output tube 3021 that can spray water mist can be adjusted, thereby adjusting the spraying direction of the water mist. At the same time, the end face of the suction cup 5083 contacts the side wall of the limiting swivel 402. When the block 5051 moves downward, the piston 5084 is pulled downward, so that the suction cup 5083 and the limiting swivel 402 are fixed by negative pressure adsorption, thereby facilitating the position fixation of the arc-shaped baffle 403.

[0046] Working principle: When working, first move the equipment to the position where spraying is required, connect the input end of the water pump to the water source through a hose, turn on the water pump, and pump water from the water source into the inner cavity of the rotating cylinder 301 through the longitudinal pipe 305 and the transverse pipe 304. Then, water mist is formed through the atomizing holes 3023 on the output cylinder 3021 and the impact plate 3022 and sprayed outward to achieve spraying, thereby settling the dust in the mine;

[0047] At the same time, the drive motor 303 needs to be turned on so that the output shaft of the drive motor 303 rotates and drives the rotating cylinder 301 to rotate continuously. Since the output cylinder 3021 is evenly installed on the circumferential outer wall of the rotating cylinder 301, the output cylinder 3021 continuously sprays water mist into the mine environment as the rotating cylinder 301 rotates, thereby increasing the spray range of the water mist and improving the dust settling effect.

[0048] An arc-shaped baffle 403 is provided on the outer side of the rotating cylinder 301. The surface of the impact plate 3022 at the end of the output cylinder 3021 is in close contact with the arc-shaped baffle 403, so that the arc-shaped baffle 403 can seal the end of the output cylinder 3021 at a certain position, thereby adjusting the water mist spraying position.

[0049] Before the water mist is sprayed, the fan 504 needs to be turned on. After the fan 504 is turned on, the air in the mine cave is driven to enter the interior of the cylindrical barrel 502 through the large air inlet hole 503. After the air enters the interior of the cylindrical barrel 502, pressure is generated on the hemispherical surface at the top of the stopper 5051, pushing the stopper 5051 to move downward. At the same time, the stopper 5051 buffers the air entering the cylindrical barrel 502, so that the dust in the air has a reduced speed and falls. After the stopper 5051 moves downward, it drives the side baffle 5053 to move downward to open the exhaust hole 5052. At this time, the air is discharged from the exhaust hole 5052, and the separated dust slides along the inclined surface of the ash falling inclined block 5061 to the inclined surface of the ash falling inclined plate 5062. The dust generates pressure on the ash falling inclined plate 5062. Under the action of pressure, the two ash falling inclined plates 5062 rotate and open, and the dust slides downward to the interior of the ash storage box 507 for storage.

[0050] When the dust falling inclined plate 5062 is rotated and opened, the support block 5066 is pushed to move outward along the horizontal rod groove 5064, and then the two moving rods 5069 are driven to move away from each other, and then the longitudinal moving block 50611 is pulled upward through the connecting rod 50610, thereby driving the conductive sliding piece 50613 on the sliding rheostat 50612 to move upward. The greater the amount of dust, the greater the upward movement distance of the longitudinal moving block 50611, so that the resistance value of the circuit where the sliding rheostat 50612 is connected to the drive motor 303 is increased. The smaller the value, the faster the driving motor 303 drives the rotating drum 301. The amount of dust in the mine is monitored and reflected through the compressed rotation of the dust falling inclined plate 5062. The rotating speed of the rotating drum 301 is increased, and the centrifugal force on the water inside the rotating drum 301 is increased, thereby increasing the pressure of the water mist sprayed out from the end of the output drum 3021, and increasing the amount and density of the water mist sprayed. The amount and density of the water mist sprayed are adapted to the amount of dust in the mine and are adaptively adjusted to ensure the dust removal effect.

[0051] When the stop block 5051 moves downward, the piston 5084 is pulled downward along the longitudinal tube 5081 by the pull rod 5085, and the end face of the suction cup 5083 at the end of the transverse tube 5082 is tightly attached to the side wall of the limiting swivel 402 on the arc baffle 403, so that the suction cup 5083 and the limiting swivel 402 are fixed by negative pressure adsorption, thereby fixing the position of the arc baffle 403. When it is necessary to adjust the water mist spraying position, the fan 504 is turned off, the limiting swivel 402 is rotated, and the position of the arc baffle 403 is adjusted so that the arc baffle 403 adjusts the blocking range of the output tube 3021, and then the arc baffle 403 is reopened, so that the suction cup 5083 and the limiting swivel 402 are again fixed by negative pressure adsorption, thereby fixing the arc baffle 403.
