Description

Technical Field

[0001] The present invention relates to the technical field of gas treatment devices, and particularly to a gas discharge device for mine safety production. Background Art

[0002] During the process of mine exploitation, harmful gases such as methane (CH4), carbon monoxide (CO), and hydrogen sulfide (H2S) are likely to accumulate in the mine shaft. Exceeding the concentration standard of these gases can easily trigger safety accidents such as explosions and poisonings. Therefore, it is necessary to discharge the internal gas of the mine in real time and introduce fresh gas to provide a good working environment for construction workers.

[0003] Existing discharge devices are mostly composed of an air pump, a pipeline, and a rectangular filter screen. The air pump is arranged at the position of the pipeline inside the mine, and the rectangular filter screen is installed inside the pipeline. Its working principle is as follows: The air pump extracts the gas in the mine and transports it through the pipeline. When the gas enters the pipeline and diffuses, the filter screen intercepts the particulate matter, and the gas continues to diffuse to the outside for treatment, thus completing the working process of the discharge device.

[0004] The filter screens of existing discharge devices mostly adopt the traditional rectangular structure design. Its planar filtration mode has functional limitations and can only achieve single-stage separation efficiency. This structural characteristic causes adherent particulate matter to easily form a dense deposition layer during long-term operation. Especially when dealing with high-viscosity sediment mixtures, the interfacial bonding strength between pollutants and the filter medium is significantly enhanced, and conventional physical cleaning methods are difficult to effectively remove deep adherent pollution. As a result, the complexity of the maintenance process increases exponentially, seriously affecting the continuous operation efficiency of the equipment. Therefore, it is urgent to propose a gas discharge device for mine safety production. Summary of the Invention

[0005] The purpose of the present invention is to address the problems of being unable to effectively clean the soil impurities attached to the filter screen and poor filtering effect in the background art, and propose a gas discharge device for mine safety production.

The piston plate is fixedly connected to the bottom end of the piston rod, and the piston plate is adapted to the inner size of the compression pipe. The first spring is fixedly connected between the fixed disk and the compression pipe.

[0010] Optionally, the transmission mechanism includes a first small pulley, a second small pulley, a belt, and a connecting rod. The first small pulley and the second small pulley are respectively arranged on the outside of the pipeline. The connecting rod is fixedly connected to the inside of the first small pulley. The end of the connecting rod away from the first small pulley is rotatably connected to the inner wall of the scraper, and the sponge is fixedly connected to the outside of the connecting rod. The belt meshes with the outside of the large pulley, the first small pulley, and the second small pulley. The belt is used to drive the large pulley, the first small pulley, and the second small pulley to rotate synchronously.

[0011] Optionally, the shaking component includes: A pressure rod connected to the end of the first small pulley away from the sponge; A triangular block connected to the outside of the pipeline; At least two first guide rods symmetrically distributed inside the scraper, and the first guide rods penetrate the scraper. Both ends of the first guide rods are fixedly connected to the inner wall of the pipeline. A second spring is sleeved on the outside of the first guide rods, and both ends of the second spring are fixedly connected to the scraper and the inner wall of the pipeline respectively; The limiting block is arranged on the outer side of the pipeline. One end of the limiting block close to the second small pulley is rotatably connected with a support rod, and the support rod is fixedly connected to the inside of the second small pulley.

[0016] Compared with the prior art, the present application includes at least one of the following beneficial technical effects: 1. Through the integrated innovation of the double-sided collaborative filtration of the drum-type filter screen and the dynamic centrifugal force throwing and attaching technology, this device realizes multi-stage efficient interception and self-cleaning: the double-surface gradient filtration breaks through the single-stage efficiency limitation, and the centrifugal force-assisted stripping of pollutants combines the scraper, sponge and soft mud liquid chemical loosening technology to effectively solve the problem of deep adhesion of high-viscosity sediment, and significantly improve the anti-blocking ability of the equipment and the stability of continuous operation.

[0017] 2. Through the synergistic effect of the friction vibration mechanism and the release of elastic potential energy, this device constructs a multi-stage adaptive cleaning mechanism: the rotation of the first small pulley drives the pressing rod. After contacting the inclined surface of the triangular block, it triggers a lateral displacement, and the linkage connecting rod pulls the scraper and the sponge away from the drum-type filter screen, realizing the periodic opening and closing of the contact surface; the first guide rod and the second spring form an elastic constraint system. When the scraper displaces, it compresses and stores energy, and during the reset stage, the elastic potential energy is instantaneously released to generate high-frequency vibration waves, which cooperate with the centrifugal force of the drum rotation to break through and improve the stripping efficiency at the interface between the high-viscosity soil and the filter screen, forming a "mechanical-elastic" dual-mode self-cleaning closed loop, and significantly enhancing the anti-adhesion ability of the equipment.

Detailed implementation manners

[0020] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Embodiment 1 As Figures 1-5As shown in the figure, a gas discharge device for mine safety production proposed by the present invention includes a pipeline 1, and further includes a drum-type filter screen 2 rotatably connected to the inner wall of the pipeline 1 and a cleaning mechanism for cleaning the drum-type filter screen 2. The cleaning mechanism includes: a cleaning component for cleaning the curved surface of the drum-type filter screen 2 and a triggering component for starting the cleaning component to perform cleaning work; when the air pump passes the gas through one side of the pipeline 1 close to the drum-type filter screen 2, the air pump is a prior art and the technology is mature, so it will not be elaborated too much. It will be guided by the triggering component, so as to force the gas to flow towards the lower half of the drum-type filter screen 2. At this time, the drum-type filter screen 2 will rotate under the action of the air flow. The dust attached to the gas needs to pass through the drum-type filter screen 2 twice (filtered by the outer surface when entering and secondarily filtered by the inner surface when passing through), which significantly improves the interception rate of fine particles. And when the drum-type filter screen 2 rotates, the dust particles in the air flow are thrown to the outer wall of the drum-type filter screen 2 and aggregated due to the centrifugal force generated by the drum-type filter screen 2, reducing the risk of blockage of the filter holes of the drum-type filter screen 2. And under the action of the wind force, the triggering component will also run synchronously. When the triggering component runs, it will drive the cleaning component to run. At this time, the cleaning component will spray water and clean the surface of the drum-type filter screen 2. The specific cleaning operation is: scraping off the soil impurities attached to the surface of the drum-type filter screen 2.

[0022] In addition, as Figure 6 , Figure 7 and Figure 8 shown, the transmission mechanism is connected to the cleaning component; when the cleaning component runs, it will drive the transmission mechanism to run.

[0023] In addition, as Figures 7-11 shown, a friction vibration mechanism is installed on the transmission mechanism. The cleaning component drives the friction vibration mechanism to reciprocate through the transmission mechanism to frictionally vibrate and clean the curved surface of the drum-type filter screen 2. The friction vibration mechanism includes: a sponge 9 for frictional contact with the curved surface of the drum-type filter screen 2; when the cleaning component runs, it will attach water to the inside of the sponge 9, and the cleaning component will also drive the sponge 9 to rotate through the transmission mechanism. At this time, the rotation directions of the sponge 9 and the drum-type filter screen 2 are opposite. When the sponge 9 applies the soft mud liquid to the outside of the drum-type filter screen 2, due to the reverse rotation force, a certain friction will be generated between the sponge 9 and the drum-type filter screen 2, so that the sponge 9 can further clean the soil on the outside of the drum-type filter screen 2.

[0024] It should be noted that, as Figures 7-11As shown, the friction vibration mechanism further includes a jitter component that vibrates the surface of the drum - type filter screen 2. When the cleaning component drives the transmission mechanism to operate, the transmission mechanism will drive the jitter component to operate. The jitter component will repeatedly impact the drum - type filter screen 2, thereby generating intermittent vibration force on the drum - type filter screen 2, making the dirt and the like attached to the outer side of the drum - type filter screen 2 fall off better. Through the above - mentioned structural design, the cleaning component realizes the water spraying and mud scraping on the drum - type filter screen 2, and the friction vibration mechanism realizes the intermittent vibration of the drum - type filter screen 2, effectively solving the problem that when the drum - type filter screen 2 processes high - viscosity sediment mixtures, the interfacial bonding strength between pollutants and the filter medium is significantly enhanced, and conventional physical cleaning means are difficult to effectively remove deep - attached pollution.

[0025] Further, as Figure 2 、 Figure 3 and Figure 4 shown, the trigger component includes a diversion block 3, a fan blade 4, a displacement sensor, a controller, and a motor 5. The following is a specific description of the trigger component: When the air - extraction pump drives the wind for discharge, under the guiding action of the diversion block 3, the wind will force the gas to flow towards the lower half of the drum - type filter screen 2. The fan blade 4 is rotatably connected to the inner wall of the pipeline 1, and the wind will also drive the fan blade 4 to rotate. The displacement sensor is installed on the fan blade 4. The displacement sensor is used to sense the rotation of the fan blade 4. When the fan blade 4 rotates, the displacement sensor will receive the rotation signal of the fan blade 4. The controller is connected to the outside of the pipeline 1. The displacement sensor transmits the rotation signal to the controller. The motor 5 is installed on the outside of the pipeline 1. The displacement sensor, the controller, and the motor 5 are all connected by radio. At this time, the controller will control the motor 5 to operate. It should be noted that the displacement sensor and the controller are both existing technologies and are technically mature, not marked in the figure, so there is no need to elaborate further. When the motor 5 operates, it will drive the cleaning component to operate.

[0026] Further, as Figure 4 and Figure 5 shown, the cleaning component includes a compression module, a scraper 7, a compression pipe 10, and a delivery pipe 11. The following is a specific description of the cleaning component: The compression tube 10 is fixedly connected to the bottom end of the pipeline 1. The compression tube 10 is filled with water (the water in the embodiment of the present invention can be any liquid on the market that does not pollute the environment). The water enters through the liquid inlet of the compression tube 10. It should be noted that the liquid inlet of the compression tube 10 is provided with a one-way valve. The one-way valve ensures that liquid or gas can only enter through the liquid inlet and cannot be discharged. The liquid inlet of the compression tube 10 is a prior art and is not marked in the figure. It is located on the outside of the compression tube 10. The delivery pipe 11 is fixedly connected to the bottom end of the compression tube 10. Between the scraper 7 and the compression module, the compression module is connected to the output end of the motor 5, and is used to compress the soft mud liquid inside the compression tube 10 into the scraper 7. When the motor 5 is running, it will drive the compression module to reciprocate and compress the internal liquid of the compression tube 10. Under the action of pressure, the liquid will enter the interior of the scraper 7 through the delivery pipe 11, and then adhere to the inside of the sponge 9 through the scraper 7. As the sponge 9 rotates, the sponge 9 adheres the liquid to the outside of the drum filter 2, thereby softening the mud, making it easier for the scraper 7 to scrape it off.

[0027] Among them, Figure 4 and Figure 5 As shown, the compression module includes a large pulley 6, a fixed rod 12, a rectangular rod 13, a fixed plate 14, a piston rod 15, a piston plate 16 and a spring 17. The following is a detailed description of the compression module: The large pulley 6 is fixedly connected to the outside of the output end of the motor 5. The operation of the motor 5 drives the large pulley 6 to rotate. The fixed rod 12 is fixedly connected to the end of the large pulley 6 away from the motor 5. The rotation of the large pulley 6 will drive the fixed rod 12 to rotate synchronously. The rectangular rod 13 is rotatably connected to the outside of the fixed rod 12. In the initial state, the fixed rod 12 is located above the large pulley 6. As the large pulley 6 rotates, the large pulley 6 will drive the fixed rod 12 to do a circular motion. The fixed rod 12 will squeeze the rectangular rod 13 to swing. The end of the rectangular rod 13 away from the fixed rod 12 is connected to the fixed disk 14. Hinge, as the fixed rod 12 gradually squeezes the rectangular rod 13, the rectangular rod 13 and the fixed plate 14 will move downward under the action of gravity and the pressure of the fixed rod 12, and the piston rod 15 is fixed to the bottom end of the fixed plate 14. The downward movement of the fixed plate 14 drives the piston rod 15 downward. The piston plate 16 is fixed to the bottom end of the piston rod 15, and the piston plate 16 is adapted to the internal size of the compression tube 10. When the piston rod 15 moves downward, it drives the piston plate 16 to compress the internal liquid of the compression tube 10. The spring 17 is fixed between the fixed plate 14 and the compression tube 10. Figure 5As shown, in the initial state, the first spring 17 is in a deformed and stretched state. As the large pulley 6 drives the fixed rod 12 to gradually squeeze the rectangular rod 13, the first spring 17 will gradually release its elastic potential energy. Cooperating with the squeezing and swinging of the fixed rod 12 on the rectangular rod 13, it synchronously pulls the fixed disk 14 downward, ensuring the stability of the downward movement of the fixed disk 14. Finally, the liquid inside the compression tube 10 will enter the inside of the scraper 7 through the delivery pipe 11.

[0028] Among them, as Figure 7 and Figure 8 shown, the transmission mechanism includes a first small pulley 18, a second small pulley 19, a belt 20 and a connecting rod 8. The following is a specific description of the transmission mechanism: The first small pulley 18 and the second small pulley 19 are respectively arranged on the outer side of the pipeline 1. The connecting rod 8 is fixedly connected inside the first small pulley 18. One end of the connecting rod 8 far from the first small pulley 18 is rotatably connected to the inner wall of the scraper 7, and the sponge 9 is fixedly connected to the outer side of the connecting rod 8. The belt 20 is engaged with the outer sides of the large pulley 6, the first small pulley 18 and the second small pulley 19. The belt 20 is used to drive the large pulley 6, the first small pulley 18 and the second small pulley 19 to rotate synchronously. When the motor 5 drives the large pulley 6 to rotate, the large pulley 6 will drive the second small pulley 19 and the first small pulley 18 to rotate synchronously through the belt 20. When the first small pulley 18 rotates, it will drive the connecting rod 8 to rotate. Since the connecting rod 8 is fixedly connected to the sponge 9, when the connecting rod 8 rotates, it will also drive the sponge 9 to rotate. At this time, the sponge 9 and the drum - type filter screen 2 rotate in opposite directions. The sponge 9 can further clean the soil on the outer side of the drum - type filter screen 2 due to the frictional force generated between it and the drum - type filter screen 2 during the process of applying the soft mud liquid to the outer side of the drum - type filter screen 2.

[0029] Furthermore, as Figures 7-11 shown, the shaking assembly includes: The pressing rod 21 is connected to the end of the first small pulley 18 far from the sponge 9. When the first small pulley 18 rotates, it will drive the pressing rod 21 to rotate counterclockwise. The triangular block 22 is connected to the outer side of the pipeline 1. When the first small pulley 18 rotates, it will drive the pressing rod 21 to rotate counterclockwise; It should be noted that as Figure 8 、 Figure 9 and Figure 10As shown, there are at least two guide rods 23 symmetrically distributed inside the scraper 7, and the guide rods 23 penetrate the scraper 7. Both ends of the guide rods 23 are fixedly connected to the inner wall of the pipeline 1. When the scraper 7 moves, it will move stably along the outer sides of the two guide rods 23 to avoid shaking. A second spring 24 is sleeved on the outer sides of the guide rods 23. Both ends of the second spring 24 are fixedly connected to the scraper 7 and the inner wall of the pipeline 1 respectively. When the scraper 7 moves in the direction away from the second spring 24, the second spring 24 will deform and generate elastic potential energy. When the pressure rod 21 passes over the triangular block 22, the second spring 24 will instantaneously release the elastic potential energy, thereby pulling the scraper 7 back to its original position. When the scraper 7 returns to its original position, it will drive the scraper 7 and the first small pulley 18 to return to their original positions through the connecting rod 8. And during the process of the scraper 7 returning to its original position, it will instantaneously impact the drum - type filter net 2.

[0030] Among them, as Figure 7 and Figure 8 shown, a limit block 25 is arranged on the outer side of the pipeline 1. One end of the limit block 25 close to the second small pulley 19 is rotatably connected to a support rod 26, and the support rod 26 is fixedly connected to the inside of the second small pulley 19. When the first small pulley 18 is horizontally in position, due to the fixed length of the belt 20, the belt 20 will pull the second small pulley 19, and the second small pulley 19 will drive the limit block 25 to move in an obliquely upward direction through the support rod 26. Two pairs of first side plates 28 are fixedly connected to the outer side of the pipeline 1. Guide rods 29 are fixedly connected between the two pairs of first side plates 28. When the limit block 25 moves, it will move along the outer sides of the guide rods 29. A third spring 30 is sleeved on the outer sides of a pair of the guide rods 29. Both ends of the spring 30 are fixedly connected to the limit block 25 and the first side plate 28 respectively. When the limit block 25 moves, it will simultaneously compress the third spring 30, causing the third spring 30 to deform and generate elastic potential energy. When the limit block 25 reaches the end position, the third spring 30 can release the elastic potential energy to push the limit block 25 back to its original position. And the reaction force exerted by the third spring 30 can ensure that there is enough friction between the second small pulley 19 and the belt 20 so that the two can continue to mesh.

[0031] In addition, as Figure 8 and Figure 11 shown, a slider 27 is slidably connected to the outer side of the pipeline 1. A second side plate 31 is fixedly connected to the outer side of the pipeline 1. A pair of fourth springs 32 are fixedly connected between the slider 27 and the second side plate 31. When the slider 27 moves horizontally, the slider 27 and the second side plate 31 will cooperate to compress the fourth springs 32, causing the fourth springs 32 to deform and generate elastic potential energy. When the slider 27 finishes moving, the fourth springs 32 will release the elastic potential energy to push the slider 27 back to its original position. The working principle of the fourth springs 32 is the same as that of the third spring 30. It can not only provide the thrust for resetting, but also ensure that the first small pulley 18 and the belt 20 are in a continuous meshing state.

[0032] When the scraper 7 moves laterally and breaks away from the contact with the drum filter 2, dirt and other impurities may pass through the gap between the scraper 7 and the drum filter 2, which leads to the problem that the dirt and impurities cannot be intercepted.

[0033] To solve the above problems, this embodiment further includes a slide 33, a telescopic plate 34 and multiple sets of springs 35, such as Figure 4 and Figure 12 As shown, the chute 33 is opened inside the scraper 7, the telescopic plate 34 is slidably connected to the inside of the chute 33, and multiple groups of springs 5 35 are fixed between the telescopic plate 34 and the chute 33. In the initial state, the telescopic plate 34 and the drum filter 2 are in a fitted state, and the spring 5 35 is in a compressed state. It should be noted that the elastic potential energy of the spring 5 35 is small, and the friction between the telescopic plate 34 and the drum filter 2 will not interfere with the normal rotation of the drum filter 2 under the action of wind. When the scraper 7 moves laterally, the scraper 7 will be separated from the drum. The expansion plate 34 is moved upwards by the spring 35, and the expansion plate 34 is pushed upwards by the spring 35. The expansion plate 34 is pushed ...

[0034] Among them, Figure 8 As shown, the sponge 9 is made of hydrophilic flexible polyurethane material, which can better absorb soft mud liquid, and has an indentation hardness between 1.62-1.68. It has a certain hardness and can generate a certain friction with the drum filter 2, making it easier to clean the soil impurities attached to the outside of the drum filter 2.

[0035] In addition, if Figure 5 As shown, the delivery pipe 11 is an EPDM rubber hose, which has good flexibility and good water permeability, and is suitable for the environment of soft mud liquid delivery.

[0036] Example 2 like Figure 3 As shown, based on Example 1, a storage box 36 is fixedly connected to the bottom end of the pipe 1, and an inspection door 37 is provided on the outside of the storage box 36. The soil and impurities scraped from the outside of the drum filter 2 will fall into the inside of the storage box 36 under the action of gravity, and the inspection door 37 can be opened to clean the soil and impurities accumulated inside the storage box 36.

[0037] The implementation principle of the present invention is as follows: When the air pump draws gas into one side of the pipeline 1 close to the fan blade 4, the air pump is a prior art and the technology is mature, so it will not be elaborated in detail. It will be guided by the guide block 3, forcing the gas to flow towards the lower half of the drum-type filter screen 2. At this time, the drum-type filter screen 2 will rotate under the action of the air flow. The dust attached to the gas needs to pass through the drum-type filter screen 2 twice. When the drum-type filter screen 2 rotates, the dust and soil attached to the outer side of the drum-type filter screen 2 will be blocked by the scraper 7 and then scraped off by the scraper 7; When the gas flows, it will also drive the fan blade 4 to rotate. When the fan blade 4 rotates, the displacement sensor will receive the rotation signal of the fan blade 4. The displacement sensor transmits the rotation signal to the controller, and the controller will then control the operation of the motor 5. The operation of the motor 5 will drive the large pulley 6 to Figure 4 rotate counterclockwise from the Figure 4 perspective. The rotation of the large pulley 6 will drive the fixed rod 12 to rotate synchronously. The rectangular rod 13 is rotatably connected to the outside of the fixed rod 12. In the initial state, the fixed rod 12 is located above the large pulley 6. As the large pulley 6 rotates, the large pulley 6 will drive the fixed rod 12 to make a circular motion, and the fixed rod 12 will squeeze the rectangular rod 13 to swing. As the fixed rod 12 gradually squeezes the rectangular rod 13, the rectangular rod 13 and the fixed disk 14 will move downward under the action of gravity and the pressure of the fixed rod 12. The downward movement of the fixed disk 14 will drive the piston rod 15 to move downward, and the downward movement of the piston rod 15 will drive the piston plate 16 to compress the soft mud liquid inside the compression tube 10. The first spring 17 is in a deformed and stretched state in the initial state. As the large pulley 6 drives the fixed rod 12 to gradually squeeze the rectangular rod 13, the first spring 17 will gradually release its elastic potential energy, cooperate with the squeezing and swinging of the fixed rod 12 on the rectangular rod 13, and synchronously pull the fixed disk 14 downward to ensure the stability of the downward movement of the fixed disk 14. Finally, the soft mud liquid inside the compression tube 10 will enter the inside of the scraper 7 through the delivery pipe 11, and then adhere to the inside of the sponge 9 through the scraper 7. As the drum-type filter screen 2 rotates, the drum-type filter screen 2 will drive the sponge 9 to attach the soft mud liquid to the outside of the drum-type filter screen 2, thereby softening the soil and facilitating the scraper 7 to scrape it off; When the large pulley 6 rotates, since the large pulley 6, the first small pulley 18 and the second small pulley 19 are all in a meshing state, the large pulley 6 will drive the first small pulley 18 to rotate through the belt 20. The rotation of the first small pulley 18 will drive the connecting rod 8 to rotate, and the rotation of the connecting rod 8 will drive the sponge 9 to rotate. At this time, the rotation directions of the sponge 9 and the drum-type filter screen 2 are opposite. The sponge 9 can generate a certain friction with the drum-type filter screen 2 due to the reverse rotation force during the process of applying the soft mud liquid to the outside of the drum-type filter screen 2, further cleaning the soil on the outside of the drum-type filter screen 2; When the first small pulley 18 rotates, it will drive the pressure rod 21 to rotate counterclockwise. When the pressure rod 21 rotates, it will contact the inclined surface of the triangular block 22. Since the position of the triangular block 22 is fixed, the pressure rod 21 will drive the first small pulley 18 to move horizontally. When the first small pulley 18 moves horizontally, it will drive the sponge 9 and the scraping plate 7 to move synchronously through the connecting rod 8, so that the scraping plate 7 and the sponge 9 are separated from the contact with the drum-type filter net 2. When the scraping plate 7 moves away from the second spring 24, the second spring 24 will deform and generate elastic potential energy. When the pressure rod 21 crosses the triangular block 22, the second spring 24 will instantaneously release the elastic potential energy, thereby pulling the scraping plate 7 back to its original position. When the scraping plate 7 returns to its original position, it will drive the scraping plate 7 and the first small pulley 18 to return to their original positions through the connecting rod 8. And during the process of the scraping plate 7 returning to its original position, it will instantaneously impact the drum-type filter net 2, thereby generating an intermittent vibration force on the drum-type filter net 2, making the soil and the like attached to the outside of the drum-type filter net 2 fall off better. When the first small pulley 18 is in the horizontal position, due to the fixed length of the belt 20, the belt 20 will pull the second small pulley 19, and the second small pulley 19 will drive the limit block 25 to move in an obliquely upward direction through the support rod 26. And when the limit block 25 moves, it will synchronously compress the third spring 30, making the third spring 30 deform and generate elastic potential energy. When the limit block 25 reaches the end, the third spring 30 can release the elastic potential energy, push the limit block 25 back to its original position, and the reaction force exerted by the third spring 30 can ensure that there is enough friction between the second small pulley 19 and the belt 20, so that the two can continue to mesh. When the slider 27 moves horizontally, the slider 27 and the second side plate 31 will squeeze the fourth spring 32, making the fourth spring 32 deform and generate elastic potential energy. When the slider 27 finishes moving, the fourth spring 32 will release the elastic potential energy, thereby pushing the slider 27 back to its original position. The working principle of the fourth spring 32 is the same as that of the third spring 30. It can not only provide the thrust for resetting, but also ensure that the first small pulley 18 and the belt 20 are in a continuous meshing state; In the initial state, the telescopic plate 34 is in contact with the drum-type filter net 2, and the fifth spring 35 is in a compressed state. It should be noted that the elastic potential energy of the fifth spring 35 is relatively small, and the frictional force between the telescopic plate 34 and the drum-type filter net 2 will not interfere with the normal rotation of the drum-type filter net 2 under the action of wind. When the scraping plate 7 moves horizontally, the scraping plate 7 will be separated from the contact with the drum-type filter net 2, and the scraping plate 7 will also drive the telescopic plate 34 to move synchronously. Since the telescopic plate 34 moves, the pressure received by the fifth spring 35 gradually decreases, and the fifth spring 35 will gradually release the elastic potential energy, pushing the telescopic plate 34 upward. Although the telescopic plate 34 also moves horizontally, under the thrust of the fifth spring 35, the telescopic plate 34 will still move upward and remain in contact with the drum-type filter net 2, thus avoiding the situation that a gap will be generated between the drum-type filter net 2 and the scraping plate 7 when the scraping plate 7 moves, and effectively intercepting soil impurities.
