[0002] Gold mining will produce dust, which will have adverse effects on the working environment and the health of workers. Dust will reduce visibility at the work site and increase the risk of accidents: mining ventilation equipment is to transport fresh air from the ground to various work points underground through wind pipes, while using local ventilation equipment to strengthen local area ventilation, air purification equipment to remove dust and harmful gases, and ventilation structures to adjust the airflow; However, during gold mining, due to the large number of solid particles in the dust, it is easy to adhere to the outer wall of the filter plate. After long-term use, there will be more impurities on the surface of the filter plate, which will reduce the filtering effect of the filter plate; at the same time, when the filtering effect of the filter plate is poor, the airflow of the ventilation device cannot be discharged, and the airflow rushes back and forth in the inner cavity of the device, thereby causing the impeller, casing and other parts of the fan to be scoured and corroded by the airflow, resulting in the problem of reduced material performance; A ventilation device for coal mining (publication number CN 212039535U), the patented technology is to install a dust cleaning mechanism on both the left and right ends of the ventilation box, the dust cleaning mechanism includes a driving motor, the output end of the driving motor is connected to an output shaft, the middle outer side of the output shaft is connected to a mounting block, the outer side of the mounting block is connected to a positioning frame, the middle outer side of the positioning rod is connected to a limited block, the bottom of the positioning rod is fixedly installed with a cleaning shaft, the rear side of the cleaning shaft is provided with a cleaning brush, and the rear side of the cleaning brush is connected with a filter screen, which is convenient for automatic cleaning, greatly improves the work efficiency of workers, and effectively solves the problems of the prior art, but its structure still needs to be improved, as follows: In this solution, a driving motor is used to drive the cleaning structure to operate. The driving motor will cause the device to have high energy consumption. Since the poor environment in the mine will affect the life of electrical equipment, the driving motor needs regular maintenance. Otherwise, damage to the driving motor will cause the cleaning structure to fail. Since the microporous structure of the filter plate adsorbs foreign particles, the cleaning shaft and the cleaning brush slide on the outer surface of the filter and are difficult to clean.

[0013] As a preferred solution of the present invention, a rack is slidably connected to the inner wall of the limit shell, wherein a compression spring is connected to the outer wall of the rack, and a driving gear is meshingly connected to the outer wall of the rack, a connecting protrusion is rotatably connected to one side of the limit shell and located on the outer wall of the rack, a limit pull rod is installed on one end of the connecting protrusion, a connecting block is rotatably connected to the outer wall of the limit pull rod, and one end of the connecting block is connected to the limit frame.

[0014] As a preferred solution of the present invention, a protective cover is installed at the port of the fan, the controller is connected to a magnetic sensor through a wire and the connection is electrical, the baffle plate is inclined 30 degrees relative to the inner wall of the box, and the graphene adsorption plate is located on one side of the grille plate, and the diversion shell serves to limit the sealing plate.

[0015] A method for using a gold mining ventilation device, the steps are as follows: Operation step 1: Turn on the switch of the controller so that the controller controls the fan to operate. When the fan is running, the fan will inhale the dust gas from the outside, and then the airflow generated by the fan will enter the inner cavity of the box. First, the airflow contacts the material blocking grille, and the solid particles collide with the material blocking grille and are blocked, so that the particles slide down along the surface of the material blocking grille. At this time, the particles fall into the inner cavity of the installation shell along the material blocking plate, and then are collected in the inner cavity of the drawer. Then, when the airflow passing through the material blocking grille is subjected to the adsorption filter plate, the dust impurities are adsorbed by the adsorption filter plate, and then the filtered gas is filtered again through the subsequent graphene adsorption plate; Operation step 2: When the adsorption filter plate is blocked by dust and impurities, the gas cannot pass through the adsorption filter plate, which will cause the gas in the inner cavity of the box to flush. At this time, the gas will flush the diversion component along the adsorption filter plate, and then the airflow will flush the closed plate, so that the closed plate is forced to drive the positioning block to move, and then the closed plate drives the positioning block to rotate on the outer wall of the rotating shaft. At the same time, the closed plate applies an extrusion force to the limit spring, so that the limit spring is compressed; Operation step three: At the same time, the sealing plate slides and unfolds on the outer wall of the connecting rod, so that the airflow in the inner cavity of the box flows out through the diversion shell. When the sealing plates opposite to each other at the port of the diversion shell are respectively tilted up, the magnetic sensor and the magnetic block are disconnected, and the magnetic sensor generates an electrical signal which is transmitted to the controller through the wire. When the set value is reached, the controller displays the data. When the adsorption filter plate is blocked and cannot filter, the diversion component diverts the airflow in the inner cavity of the box. Operation step 4: When the airflow passes through the ventilation hole, the airflow drives the impeller to rotate. When the impeller rotates, the impeller drives the connecting rod to rotate. When the connecting rod rotates, the connecting rod drives the second driving rod to rotate. When the second driving rod rotates, the second driving rod drives the active bevel gear to rotate, and then the active bevel gear drives the driven bevel gear to rotate through meshing connection. When the driven bevel gear rotates, the driven bevel gear drives the second rotating rod to rotate. When the second rotating rod rotates; Operation step five: Make the other end of the rotating rod drive the driving gear to rotate, and then the driving gear drives the rack to move laterally through meshing connection, which will make the rack move to one side on the inner wall of the limit housing. When the rack moves, the outer wall of the rack applies thrust to the compression spring, so that the compression spring is compressed. At the same time, one end of the rack applies tension to the limit pull rod through the connecting convex rod, which will make the limit pull rod apply tension to the limit frame through the connecting block, so that when the limit frame is stressed, its limit frame rotates around the rotating shaft, so that the limit frame is pulled out and moved to the patting cleaning position; Operation step six: the connecting rod drives the driving rod 1 to rotate. When the driving rod 1 rotates, the driving rod 1 drives the driving bevel gear to operate. When the driving bevel gear rotates, the driving bevel gear drives the connecting bevel gear to operate through meshing connection, so that the connecting bevel gear drives the rotating rod 1 to rotate, and then one end of the rotating rod 1 drives the cam crank to rotate, because the crank of the cam crank is provided with a first rotating rod; Operation step seven: when the cam crank rotates, the cam crank will drive the first rotating rod to rotate, and then the first rotating rod applies left and right rotating pulling force to the second rotating rod through the connecting plate, so that the second rotating rod applies lateral reciprocating pulling force to the fixed handle, and then the fixed handle rotates in an arc on the outer wall of the mounting rod. Since one end of the fixed handle is connected to the flapping frame through the fixed rod rotation, when the fixed handle moves left and right, the fixed handle will apply a reciprocating force to the flapping frame through the fixed rod. At the same time, since one end of the flapping frame applies an elastic thrust through the ejection spring, one end of the flapping frame is always against the bottom of the adsorption filter plate. At this time, the other end of the adsorption filter plate is reciprocated by the flapping frame, so that impurities and dust on the surface of the adsorption filter plate fall off, and then the dust falls into the inner cavity of the mounting shell for collection; Operation step eight: the airflow drives the connecting rod to rotate through the impeller, so that when the impeller drives the connecting rod to rotate, the connecting rod and the limit assembly are driven. When the dust on the surface of the adsorption filter plate blocks the adsorption filter plate, the airflow is discharged from the diversion assembly, thereby accelerating the operation of the impeller, and also making the cleaning assembly and the limit assembly run faster. The beating frame in the cleaning assembly has a higher efficiency in beating the adsorption filter plate. At this time, one end of the driving rod 2 is magnetically connected with the connecting rod. When the connecting rod rotates, the connecting rod drives the driving rod 2 to rotate through the magnetic coupling connection. When the rack moves laterally on the inner wall of the limit housing, the compression spring is compressed; Operation step nine: After the dust on the surface of the adsorption filter plate falls off, when the adsorption filter plate filters the gas normally, the airflow does not pass through the diversion component, and the compressed limit spring resets the sealing plate through elastic thrust. At this time, the impeller stops running. When the impeller drives the connecting rod to stop running, the connecting rod will stop running on the cleaning component and the limit component. At this time, the compressed compression spring loses the thrust of the rack, and then the compression spring stretches and resets, so that the compression spring pushes the rack to move in the opposite direction of the limit housing. After the limit component is reset, the limit frame will also be reset.

[0016] Compared with the prior art, the present invention, by arranging a diversion component in the gold mining ventilation equipment and its use method, can achieve that when the adsorption filter plate is blocked by dust, the airflow in the inner cavity of the box is discharged through the diversion component, and the closed plate is forced to drive the positioning block to move, and then the closed plate drives the positioning block to rotate on the outer wall of the rotating shaft, so that the airflow in the inner cavity of the box flows out through the diversion shell. When the closed plates are respectively tilted up, the magnetic sensor and the magnetic block are disconnected, and the magnetic sensor generates an electrical signal that is transmitted to the controller through the wire. When the set value is reached, the controller will display the data, thereby solving the problem that when the filtering effect is not good, the airflow of the ventilation device cannot be discharged, and it is washed back and forth in the inner cavity, so that the fan impeller, casing and other components are corroded by the airflow and the material performance is reduced.

[0017] The present invention sets a limit assembly in the gold mining ventilation equipment and its use method, so that when the connecting rod drives the driving rod two to rotate, the active bevel gear drives the driven bevel gear to rotate through the meshing connection, so that the driven bevel gear drives the rotating rod two to rotate, and the other end of the rotating rod two drives the driving gear to rotate, and then the driving gear drives the rack to move laterally through the meshing connection, and one end of the rack applies a pulling force to the limit pull rod through the connecting convex rod, which makes the limit pull rod apply a pulling force to the limit frame through the connecting block, so that when the limit frame is subjected to force, the limit frame rotates around the rotating shaft, so that the limit frame is pulled out and moved to the patting and cleaning position.

[0018] The present invention can achieve the purpose of beating the filter adsorption plate by arranging a cleaning component in the gold mining ventilation equipment and the use method thereof, thereby causing dust to fall off. When the connecting rod drives the driving rod to drive a pair of driving bevel gears, the driving bevel gears drive the connecting bevel gears to operate through meshing connection, so that the cam crank drives the first rotating rod to rotate, and then the first rotating rod applies left and right rotational pulling force to the second rotating rod through the connecting plate, which will cause the fixed handle to apply reciprocating force to the beating frame through the fixed rod. At the same time, one end of the beating frame applies elastic thrust through the ejection spring, so that one end of the beating frame is always against the bottom of the adsorption filter plate. At this time, the other end of the adsorption filter plate is reciprocatedly beaten by the beating frame, so that impurities and dust on the surface of the adsorption filter plate fall off, and then the dust falls into the inner cavity of the installation shell for collection, thereby solving the problem that dust is easy to adhere to the outer wall of the filter plate in gold mining, and impurities increase after long-term use, resulting in reduced filtering effect.

[0019] The present invention arranges multiple components in the gold mining ventilation equipment and the use method thereof to cooperate with each other and operate independently without energy consumption. When the airflow passes through the impeller and drives the connecting rod to rotate, the connecting rod drives the cleaning component and the limit component. When the airflow does not pass through the diversion component, the compressed limit spring causes the sealing plate to reset through elastic thrust. At this time, the impeller stops running, which causes the connecting rod to stop driving the cleaning component and the limit component. At this time, the compressed compression spring loses the thrust of the rack, thereby stretching and resetting the compression spring, so that the compression spring pushes the rack to move in the opposite direction of the limit housing. After the limit component is reset, the limit frame is also reset. The device operates independently through the cooperation of multiple components without energy consumption, thereby solving the problem that the driving motor drives the cleaning structure to operate, the energy consumption is high, the mine environment affects its life, and regular maintenance is required, otherwise the motor is damaged and the cleaning structure fails.

[0026] Based on the above structural features and the connection relationship, one end of the second driving rod 701 is magnetically connected to the connecting rod 411, wherein the second driving rod 701 and the connecting rod 411 are magnetically fixed through a magnetic coupling connection. When the limiting assembly 7 drives the limiting frame 19 to be pulled out and moved to the beating cleaning position, the rack 710 in the inner cavity of the limiting assembly 7 is stuck, and the stuck driving rod 701 will not affect the rotation of the connecting rod 411. Among them, a protective cover 23 is installed at the port of the fan 11, so that the protective cover 23 shields the fan 11, making the device safer. The controller 13 is connected to the magnetic sensor 407 through a wire and the connection method is electrical connection, so that the device is powered on, and then the controller 13 controls the magnetic sensor 407 to operate. The material baffle plate 17 is inclined 30 degrees relative to the inner wall of the box body 2, and the graphene adsorption plate 22 is located on one side of the grille plate 12, and the diversion shell 401 limits the sealing plate 404.

[0027] When the gold mining ventilation equipment and the method of using the same are in operation, the controller 13 is turned on to control the fan 11 to operate. When the fan 11 is in operation, the fan 11 will inhale dust gas from the outside, and then the airflow generated by the fan 11 will enter the inner cavity of the box body 2. First, the airflow contacts the material blocking grille 16, and the solid particles collide with the material blocking grille 16 and are blocked, so that the particles slide downward along the surface of the material blocking grille 16. At this time, the particles fall into the inner cavity of the installation shell 3 along the material blocking plate 17, and are then collected in the inner cavity of the drawer 8. Subsequently, when the airflow passing through the material blocking grille 16 is subjected to the adsorption filter plate 20, the dust impurities are adsorbed by the adsorption filter plate 20, and then the filtered gas is filtered again by the subsequent graphene adsorption plate 22, and the filtered gas is discharged. When the adsorption filter plate 20 is blocked by dust and impurities, the gas cannot pass through the adsorption filter plate 20, which will cause the gas in the inner cavity of the box body 2 to be flushed. At this time, the gas will flush the diverter component 4 along the adsorption filter plate 20, and then the airflow will flush the sealing plate 404, so that the sealing plate 404 is forced to drive the positioning block 403 to move, and then the sealing plate 404 drives the positioning block 403 to rotate on the outer wall of the rotating shaft 402, and at the same time, the sealing plate 404 applies an extrusion force to the limit spring 406, so that the limit spring 406 is compressed, and at the same time, the sealing plate 404 slides and expands on the outer wall of the connecting rod 411, so that the inner cavity of the box body 2 The airflow in the cavity flows out through the diverter housing 401. When the sealing plates 404 opposite to each other at the ports of the diverter housing 401 are respectively tilted up, the magnetic sensor 407 and the magnetic block 408 are disconnected, and then the magnetic sensor 407 generates an electrical signal which is transmitted to the controller 13 through the wire. When the set value is reached, the controller 13 displays the data. When the adsorption filter plate 20 is blocked and cannot be filtered, the diverter assembly 4 diverts the airflow in the inner cavity of the box body 2, thereby solving the problem that when the filtering effect is not good, the airflow of the ventilation device cannot be discharged, and it is washed back and forth in the inner cavity, so that the fan impeller, casing and other components are corroded by the airflow and the material performance is reduced. When the airflow passes through the ventilation hole 409, the airflow drives the impeller 410 to rotate. When the impeller 410 rotates, the impeller 410 drives the connecting rod 411 to rotate. When the connecting rod 411 rotates, the connecting rod 411 drives the second driving rod 701 to rotate. When the second driving rod 701 rotates, the second driving rod 701 drives the active bevel gear 703 to rotate, and then the active bevel gear 703 drives the driven bevel gear 705 to rotate through meshing connection. When the driven bevel gear 705 rotates, the driven bevel gear 705 drives the second rotating rod 704 to rotate. When the second rotating rod 704 rotates, the other end of the second rotating rod 704 drives the driving gear When the rack 710 moves, the outer wall of the rack 710 applies a thrust to the compression spring 709, so that the compression spring 709 is compressed. At the same time, one end of the rack 710 applies a pulling force to the limiting pull rod 712 through the connecting protruding rod 711, so that the limiting pull rod 712 applies a pulling force to the limiting frame 19 through the connecting block 713, so that when the limiting frame 19 is stressed, the limiting frame 19 rotates around the rotating shaft 18, so that the limiting frame 19 is pulled out and moved to the patting cleaning position. The driving rod 601 is driven to rotate by the connecting rod 411. When the driving rod 601 rotates, the driving rod 601 drives the driving bevel gear 604 to operate. When the driving bevel gear 604 rotates, the driving bevel gear 604 drives the connecting bevel gear 606 to operate through meshing connection, so that the connecting bevel gear 606 drives the rotating rod 605 to rotate, and then one end of the rotating rod 605 drives the cam crank 607 to rotate. Since the crank of the cam crank 607 is provided with a first rotating rod 608, when the cam crank 607 rotates, the cam crank 607 drives the first rotating rod 608 to rotate, and then the first rotating rod 608 applies a left and right rotational pulling force to the second rotating rod 611 through the connecting plate 609, so that the second rotating rod 611 applies a lateral reciprocating pulling force to the fixed handle 610 The force is applied to the fixed handle 610, thereby causing the fixed handle 610 to rotate in an arc shape on the outer wall of the mounting rod 603. Since one end of the fixed handle 610 is rotatably connected to the flapping frame 613 through the fixed rod 612, when the fixed handle 610 moves left and right, the fixed handle 610 will apply a reciprocating force to the flapping frame 613 through the fixed rod 612. At the same time, since one end of the flapping frame 613 applies an elastic thrust through the ejection spring 615, one end of the flapping frame 613 is always pressed against the bottom of the adsorption filter plate 20. At this time, the other end of the adsorption filter plate 20 is reciprocatedly flapped by the flapping frame 613, so that the impurities and dust on the surface of the adsorption filter plate 20 fall off, and then the dust falls into the inner cavity of the mounting shell 3 for collection, thereby solving the problem that dust is easy to adhere to the outer wall of the filter plate in gold mining, and impurities increase after long-term use, resulting in reduced filtering effect. The airflow passes through the impeller 410 to drive the connecting rod 411 to rotate, so that when the impeller 410 drives the connecting rod 411 to rotate, the connecting rod 411 will drive the cleaning component 6 and the limiting component 7. When the dust on the surface of the adsorption filter plate 20 blocks the adsorption filter plate 20, the airflow is discharged through the diversion component 4, thereby accelerating the operation of the impeller 410, and also making the cleaning component 6 and the limiting component 7 run faster. Among them, the flapping frame 613 in the cleaning component 6 has a higher flapping efficiency for the adsorption filter plate 20. At this time, one end of the driving rod 2 701 is magnetically connected to the connecting rod 411. When the connecting rod 411 rotates, the connecting rod 411 will drive the driving rod 2 701 to rotate through the magnetic coupling connection. When the rack 710 moves laterally on the inner wall of the limiting shell 707, the compression spring 709 is compressed by force. After the dust falls off, when the adsorption filter plate 20 filters the gas normally, the airflow does not pass through the diverter component 4, and the compressed limit spring 406 resets the sealing plate 404 through elastic thrust. At this time, the impeller 410 stops running. When the impeller 410 drives the connecting rod 411 to stop running, the connecting rod 411 will stop driving the cleaning component 6 and the limit component 7. At this time, the compressed compression spring 709 loses the thrust of the rack 710, and then the compression spring 709 stretches and resets, so that the compression spring 709 pushes the rack 710 to move in the opposite direction of the limit housing 707. After the limit component 7 is reset, the limit frame 19 will also be reset. The device operates independently through the cooperation of multiple components without energy consumption, thereby solving the problem that the driving motor drives the cleaning structure to operate, the energy consumption is high and the mine environment affects its life, and regular maintenance is required, otherwise the motor is damaged and the cleaning structure fails.

When the fan (11) operates, the fan (11) will suck in dust gas from the outside, thereby causing the airflow generated by the fan (11) to enter the inner cavity of the box body (2). First, the airflow contacts the material blocking grille (16), and the solid particles collide with the material blocking grille (16) and are blocked, causing the particles to slide downward along the surface of the material blocking grille (16). At this time, the particles fall into the inner cavity of the installation shell (3) along the material blocking plate (17), and are then collected in the inner cavity of the drawer (8).

When the second rotating rod (704) rotates; Operation step five: the other end of the second rotating rod (704) drives the driving gear (706) to rotate, and then the driving gear (706) drives the rack (710) to move laterally through the meshing connection, which causes the rack (710) to move to one side on the inner wall of the limiting shell (707). When the rack (710) moves, the outer wall of the rack (710) applies a thrust to the compression spring (709), so that the compression spring (709) is compressed. At the same time, one end of the rack (710) applies a pulling force to the limiting pull rod (712) through the connecting protruding rod (711), which causes the limiting pull rod (712) to apply a pulling force to the limiting frame (19) through the connecting block (713), so that when the limiting frame (19) is subjected to force, the limiting frame (19) rotates around the rotating shaft (18), and then the limiting frame (19) is pulled out and moved to the patting cleaning position; Operation step six: driving the driving rod 1 (601) to rotate through the connecting rod (411); when the driving rod 1 (601) rotates, the driving rod 1 (601) drives the driving bevel gear (604) to operate; when the driving bevel gear (604) rotates, the driving bevel gear (604) drives the connecting bevel gear (606) to operate through meshing connection, so that the connecting bevel gear (606) drives the rotating rod 1 (605) to rotate, and then one end of the rotating rod 1 (605) drives the cam crank (607) to rotate, because the crank of the cam crank (607) is provided with a first rotating rod (608); Operation step seven: When the cam crank (607) rotates, the cam crank (607) drives the first rotating rod (608) to rotate, so that the first rotating rod (608) applies a left-right rotational pulling force to the second rotating rod (611) through the connecting plate (609), so that the second rotating rod (611) applies a lateral reciprocating pulling force to the fixed handle (610), so that the fixed handle (610) rotates in an arc on the outer wall of the mounting rod (603). Since one end of the fixed handle (610) is rotatably connected to the flapping frame (613) through the fixed rod (612), when When the fixed handle (610) moves left and right, the fixed handle (610) applies a reciprocating force to the beating frame (613) through the fixed rod (612). At the same time, one end of the beating frame (613) applies an elastic thrust through the ejection spring (615), so that one end of the beating frame (613) always presses against the bottom of the adsorption filter plate (20). At this time, the other end of the adsorption filter plate (20) is reciprocatedly beaten by the beating frame (613), so that impurities and dust on the surface of the adsorption filter plate (20) fall off, and then the dust falls into the inner cavity of the mounting shell (3) for collection; Operation step eight: The airflow passes through the impeller (410) to drive the connecting rod (411) to rotate, so that when the impeller (410) drives the connecting rod (411) to rotate, the connecting rod (411) drives the cleaning component (6) and the limiting component (7).

At this time, the impeller (410) stops running. When the impeller (410) drives the connecting rod (411) to stop running, the connecting rod (411) stops running on the cleaning assembly (6) and the limit assembly (7). At this time, the compressed compression spring (709) loses the thrust of the rack (710), and the compression spring (709) is stretched and reset, so that the compression spring (709) pushes the rack (710) to move in the opposite direction in the limit housing (707).
