Technical Field
[0001] This invention relates to the field of building materials testing technology, specifically to a wear resistance testing device for building materials used in construction projects. Background Technology
[0002] Building materials are used to construct various functional parts of buildings, including structure, decoration, insulation, and waterproofing. The choice of building materials directly affects the quality, durability, safety, and aesthetics of a building. Building materials face various frictions and wear conditions during use; for example, concrete floors are subjected to friction from foot traffic and moving objects. Concrete is a building material, referring to a general term for engineering composite materials made by binding aggregates together with cementing materials. It is composed of cement, sand, gravel, and water, and after mixing, it is usually poured into molds and hardens during the curing process, forming a strong structural material. Concrete is widely used in construction projects. Therefore, abrasion resistance testing of concrete blocks is necessary, and abrasion resistance testing equipment can be used for this purpose.
[0003] Currently, traditional concrete block abrasion resistance testing equipment grinds hard stones inside the concrete block during the grinding process, causing the grinding tool to shake, resulting in poor overall structural stability, affecting the grinding effect on the concrete block, and in severe cases, even damaging the grinding tool. Summary of the Invention
[0004] To achieve the above objectives, the present invention provides the following technical solution: A wear resistance testing device for building materials used in construction engineering includes: The machine body and the cabinet, wherein a rotating mechanism is installed at the bottom of the internal cavity of the machine body; A grinding mechanism for grinding concrete in construction projects, the grinding mechanism being installed at the top of the internal cavity of the machine; The grinding mechanism includes a hydraulic cylinder and a plate. The hydraulic cylinder is fixedly installed on the top of the machine body, and the plate is fixedly installed on the telescopic end of the hydraulic cylinder. A rotating shaft is rotatably installed at the middle of the bottom of the plate, and a servo motor is fixedly installed on the side of the bottom of the plate. A toothed turntable is fixedly connected to the output end of the servo motor. Right-angle teeth are fixedly connected to the outer circular surface of the rotating shaft, and a grinding ball head is fixedly connected to the bottom end of the rotating shaft. A cleaning component is installed at the bottom of the outer circular surface of the rotating shaft, and a ball bearing is rolled at the top edge of the grinding ball head. By extending and retracting the telescopic end of the hydraulic cylinder, the plate can be moved downward and upward, thereby moving the rotating shaft and the servo motor together. This allows the grinding ball head to move downward and upward with the rotating shaft, facilitating the adjustment of the height of the grinding ball head and promoting contact and separation between the grinding ball head and the concrete block to be inspected. The cleaning assembly includes a cleaning disc and a connecting rod. The center of the cleaning disc is rotatably mounted to the bottom of the outer circular surface of the rotating shaft. The bottom end of the connecting rod is fixedly connected to the protrusion on the top of the cleaning disc. An elastic strip is fixedly connected to the side of the top of the cleaning disc by a pad. A scraper is fixedly connected to the middle of the bottom of the elastic strip. An elastic brush is fixedly connected to the edge of the bottom of the cleaning disc. The servo motor output drives the toothed turntable to rotate, so that the connecting rod is subjected to the paving force of the toothed turntable. Under the rotation support of the rotating shaft, the toothed turntable rotates. The rotation direction of the toothed turntable is opposite to the rotation direction of the grinding ball head, and the bottom of the scraper is in contact with the top of the concrete block. As the scraper rotates, the grinding shavings discharged from the grinding ball head are scraped. With the continuous circumferential rotation of the scraper, the grinding shavings are guided to move outward by the scraper, and the grinding shavings are initially scraped off. As the extension end of the hydraulic cylinder extends, the rotating shaft drives the cleaning disc to move downward. The scraper slides upward after being subjected to the reverse force, and the elastic strip is pushed and undergoes elastic deformation.
[0005] Preferably, the rotating shaft and the hydraulic cylinders are installed vertically. There are two hydraulic cylinders, and the two hydraulic cylinders are symmetrically installed along the rotating shaft. The rotation of the servo motor output can drive the toothed turntable to rotate. The right-angle teeth mesh with the teeth on the surface of the toothed turntable, so that the right-angle teeth are subjected to a pulling force. With the rotational support of the rotating shaft by the plate, and with the right-angle teeth installed below the plate, the rotating shaft can drive the grinding ball head to rotate smoothly without shaking. This facilitates the grinding ball head to stably grind the concrete block to be tested and perform wear resistance testing on the concrete block.
[0006] Preferably, the right-angled teeth are evenly distributed on the outer circumference of the rotating shaft, and the right-angled teeth are meshed with the teeth on the surface of the toothed disc. The rotating shaft drives the grinding ball head to rotate and grind the concrete block. The spiral pattern on the surface of the grinding ball head can transport the grinding debris upward, which facilitates the discharge of the grinding debris and reduces the wear of the grinding ball head on the grinding debris.
[0007] Preferably, the balls are evenly distributed at the edge of the top of the grinding ball head, and the spherical surface of the balls is rotatably mounted to the top of the inner side of the cleaning disc, and the top of the spherical surface of the grinding ball head is internally tangent to the top of the inner side of the cleaning disc.
[0008] The rotation of the cleaning disc drives the elastic brush to rotate as well, which in turn brushes away the abrasive debris scraped off by the scraper, thus keeping the top of the concrete block clean.
[0009] Preferably, the connecting rod is installed vertically, the connecting rod is evenly distributed along the circumferential direction of the central axis of the rotating shaft, and the top end of the connecting rod is engaged with the teeth on the surface of the toothed rotating disk.
[0010] Preferably, there are four elastic strips, which are evenly distributed on the side of the top of the sweeping disc. The scraper passes through the sweeping disc and extends to its bottom, and the scraper is slidably installed between the scraper and the sweeping disc.
[0011] Preferably, the rotating mechanism includes a power source. The bottom of the power source is fixedly installed to the bottom of the internal cavity of the machine body by screws. A four-jaw chuck is fixedly installed at the output end of the top of the power source. A right-angled top rod is hinged to the side of the top of the power source. A return spring is fixedly connected between the inner side of the right-angled top rod and the top of the power source. A striking ball is rolled on the top of the right-angled top rod. Rotating the right-angled top rod counterclockwise causes the striking ball to move away from above the four-jaw chuck, and the return spring is stretched. This facilitates the four-jaw chuck to clamp and fix the concrete block that needs wear resistance testing. The power source provides power, and the output end of the power source drives the four-jaw chuck to rotate, causing the concrete block to rotate as well. The direction of rotation of the concrete block is opposite to the direction of rotation of the grinding ball head, which can improve the grinding efficiency of the grinding ball head on the concrete block.
[0012] Preferably, the reset spring is installed at an angle, the striking ball is hollow, and the striking ball is installed directly above the four-jaw chuck. As the grinding ball head and the sweeping disc move downward together, and the bottom of the grinding ball head contacts the top of the concrete block, the right-angled top rod can be released. Under the elastic tension of the reset spring, the right-angled top rod drives the striking ball to rotate clockwise for reset. As the sweeping disc rotates, the edge of the top of the scraper contacts the striking ball, causing the striking ball to receive an upward pushing force. The reset spring is stretched again. As the scraper continues to rotate, the scraper separates from the striking ball, and under the elastic tension of the reset spring, the right-angled top rod drives the striking ball to rotate in the opposite direction. The striking ball strikes the sweeping disc, causing the sweeping disc to vibrate. Under the action of vibration, dust and debris fall off the scraper and elastic brush, thus achieving self-cleaning.
[0013] Preferably, a dust removal mechanism is fixedly installed on the bottom of the machine body surface. The dust removal mechanism includes a water tank, the surface of which is fixedly installed to the bottom of the machine body surface. An air outlet is fixedly installed on the side of the top of the water tank, and a drain pipe is fixedly installed on the side of the bottom of the water tank. A suction fan is fixedly installed on the side of the top of the inner cavity of the water tank. A J-shaped air guide plate is fixedly connected to the middle of the inner cavity of the water tank. A partition is fixedly connected to the surface of the J-shaped air guide plate and on the side away from the suction fan. The partition is installed at an angle, and a vent hole is opened on the top of the surface of the partition for air intake by the suction fan. The suction force generated absorbs the dust and debris brushed away by the elastic brush. The air outlet of the suction fan applies a blowing force between the J-shaped air guide plate and the inside of the water tank, creating a pressure difference that causes the water level to slowly drop until a narrow gap appears between the bottom of the J-shaped air guide plate and the bottom of the water tank cavity. This allows dust-laden air to enter the water between the J-shaped air guide plate and the partition. The water is turbulent under the airflow, splashing water everywhere, which allows the air and water to come into full contact. The water carries away the dust and debris, forming a water vortex for dust removal, while the gas passes through the vent holes and is discharged from the air outlet, thus achieving dust suppression.
[0014] Preferably, there are two water tanks, and the two water tanks are symmetrically installed along the central axis in the middle of the machine body. The bottom of the air outlet is connected to the water tank, and the air vents are evenly distributed on the top of the partition surface.
[0015] This invention provides a wear resistance testing device for building materials used in construction engineering. It has the following beneficial effects: I. The abrasion resistance testing equipment for building materials used in this construction project utilizes the extension and retraction of the hydraulic cylinder's telescopic end to move the flat plate downwards and upwards, thereby moving the rotating shaft and servo motor together. This allows the grinding ball head to move downwards and upwards along with the rotating shaft, facilitating the adjustment of the grinding ball head's height and promoting contact and separation between the grinding ball head and the concrete block to be tested.
[0016] II. This abrasion resistance testing equipment for building materials used in construction projects utilizes the rotation of the output end of a servo motor to drive the toothed turntable to rotate. The right-angle teeth mesh with the teeth on the surface of the turntable, causing the right-angle teeth to receive a pulling force. With the support of the rotating shaft on a flat plate, and the right-angle teeth mounted below the plate, the rotating shaft can drive the grinding ball head to rotate smoothly without wobbling. This facilitates stable grinding of the concrete block to be tested by the grinding ball head, enabling abrasion resistance testing of the concrete block.
[0017] Third, the abrasion resistance testing equipment for building materials used in this construction project uses a rotating shaft to drive a grinding ball head to grind concrete blocks. The spiral pattern on the surface of the grinding ball head can transport the grinding debris upwards, making it easier for the debris to be discharged and reducing the wear of the grinding ball head on the debris.
[0018] IV. The abrasion resistance testing equipment for building materials used in this construction project utilizes the connecting rod to be driven by the toothed turntable, causing the toothed turntable to rotate. As the scraper rotates, it scrapes the abrasive shavings discharged from the grinding ball head. With the continuous circumferential rotation of the scraper, the abrasive shavings are guided outward by the scraper, performing preliminary scraping of the abrasive shavings. As the extension end of the hydraulic cylinder extends, the rotating shaft drives the cleaning disc to move downward. The scraper slides upward after being subjected to the reverse force, and the elastic strip is pushed and undergoes elastic deformation, preventing the structure from jamming.
[0019] 5. The abrasion resistance testing equipment for building materials used in this construction project can rotate the elastic brush by rotating the cleaning disc. The elastic brush can then brush away the abrasion debris scraped off by the scraper, thus keeping the top of the concrete block clean.
[0020] VI. The abrasion resistance testing equipment for building materials used in this construction project uses a four-jaw chuck to clamp and fix the concrete block that needs to be tested for abrasion resistance. The power source drives the four-jaw chuck to rotate, causing the concrete block to rotate along with it. The direction of rotation of the concrete block is opposite to the direction of rotation of the grinding ball head, which can improve the grinding efficiency of the grinding ball head on the concrete block.
[0021] VII. The abrasion resistance testing equipment for building materials used in this construction project, as the sweeping disc rotates, the top edge of the scraper contacts the striking ball, causing the striking ball to receive an upward pushing force. The scraper separates from the striking ball, and under the elastic tension of the return spring, the right-angled top rod drives the striking ball to rotate in the opposite direction. The striking ball strikes the sweeping disc, causing the sweeping disc to vibrate. Under the action of vibration, dust and debris fall off the scraper and elastic brush, thus enabling self-cleaning.
[0022] 8. The abrasion resistance testing equipment for building materials used in this construction project applies a blowing force from the exhaust end of the suction fan to the interior of the J-shaped air guide plate and the water tank. The pressure difference causes the water level to slowly drop until a narrow gap appears between the bottom of the J-shaped air guide plate and the bottom of the water tank cavity. This allows dusty air to enter the water between the J-shaped air guide plate and the partition. The water is turbulent under the airflow, and water splashes everywhere, allowing the air and water to come into full contact. The water carries away the dust and debris, forming a water vortex for dust removal. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0026] First embodiment, such as Figures 1 to 5 As shown, the present invention provides a technical solution: A wear resistance testing device for building materials used in construction engineering includes: The unit 1 and the cabinet 2 are equipped with a rotating mechanism 3 installed at the bottom of the inner cavity of the unit 1. Grinding mechanism 4 is used to grind concrete in construction projects. Grinding mechanism 4 is installed on the top of the inner cavity of machine body 1. The grinding mechanism 4 includes a hydraulic cylinder 41 and a plate 42. The hydraulic cylinder 41 is fixedly installed on the top of the machine body 1, and the plate 42 is fixedly installed on the telescopic end of the hydraulic cylinder 41. A rotating shaft 43 is rotatably installed at the middle of the bottom of the plate 42. A servo motor 44 is fixedly installed on the side of the bottom of the plate 42. A toothed turntable 45 is fixedly connected to the output end of the servo motor 44. A right-angle tooth 46 is fixedly connected to the outer circular surface of the rotating shaft 43. A grinding ball head 47 is fixedly connected to the bottom end of the rotating shaft 43. A cleaning component 48 is installed at the bottom of the outer circular surface of the rotating shaft 43. A ball bearing 49 is rolled at the top edge of the grinding ball head 47. When the operator starts the hydraulic cylinder 41, the plate 42 can be moved downward and upward by extending and retracting the telescopic end of the hydraulic cylinder 41. This moves the rotating shaft 43 and the servo motor 44 together, so that the grinding ball head 47 can move downward and upward along with the rotating shaft 43, making it easy to adjust the height of the grinding ball head 47. The rotating shaft 43 is installed vertically, and the hydraulic cylinder 41 is installed vertically. There are two hydraulic cylinders 41, and the two hydraulic cylinders 41 are installed symmetrically along the rotating shaft 43.
[0027] The operator starts the servo motor 44 to operate. The rotation of the output end of the servo motor 44 drives the toothed turntable 45 to rotate. The right-angle teeth 46 mesh with the teeth on the surface of the toothed turntable 45, so that the right-angle teeth 46 are subjected to a pulling force. With the support of the rotating shaft 43 by the plate 42 and the right-angle teeth 46 installed below the plate 42, the rotating shaft 43 can drive the grinding ball head 47 to rotate smoothly without shaking. This makes it easy for the grinding ball head 47 to stably grind the concrete block to be tested.
[0028] Right-angle teeth 46 are evenly distributed on the outer surface of the rotating shaft 43, and are engaged with the teeth on the surface of the toothed disc 45.
[0029] The grinding ball head 47 is rotated by the rotating shaft 43 to grind the concrete block. The spiral pattern on the surface of the grinding ball head 47 can transport the grinding debris upward, which facilitates the discharge of the grinding debris and reduces the wear of the grinding ball head 47.
[0030] The cleaning assembly 48 includes a cleaning disc 481 and a connecting rod 482. The center of the cleaning disc 481 is rotatably mounted to the bottom of the outer surface of the rotating shaft 43. The bottom end of the connecting rod 482 is fixedly connected to the protrusion on the top of the cleaning disc 481. An elastic strip 483 is fixedly connected to the side of the top of the cleaning disc 481 via a pad. A scraper 484 is fixedly connected to the middle of the bottom of the elastic strip 483. An elastic brush 485 is fixedly connected to the edge of the bottom of the cleaning disc 481. The output end of the servo motor 44 drives the toothed turntable 45 to rotate, and the top end of the connecting rod 482 is engaged with the teeth on the surface of the toothed turntable 45, so that the connecting rod 482 is pushed by the toothed turntable 45. Force, and under the rotational support of the rotating shaft 43, causes the toothed disc 45 to rotate, and the rotation direction of the toothed disc 45 is opposite to the rotation direction of the grinding ball head 47. The bottom of the scraper 484 is in contact with the top of the concrete block. As the scraper 484 rotates, it can scrape the grinding debris discharged from the grinding ball head 47. As the scraper 484 continues to rotate in a circular motion, the grinding debris is guided by the scraper 484 to move outward, and the grinding debris is initially scraped off. As the extension end of the hydraulic cylinder 41 extends, the rotating shaft 43 drives the cleaning disc 481 to move downward. The scraper 484 slides upward after being subjected to the reverse force, and the elastic strip 483 is pushed and deformed elastically.
[0031] The balls 49 are evenly distributed on the edge of the top of the grinding ball head 47, and the spherical surface of the balls 49 is rotatably mounted to the top of the inner side of the cleaning disc 481, and the top of the spherical surface of the grinding ball head 47 is internally tangent to the top of the inner side of the cleaning disc 481.
[0032] The connecting rod 482 is installed vertically and is evenly distributed along the circumference of the central axis of the rotating shaft 43. The top of the connecting rod 482 is engaged with the teeth on the surface of the toothed rotating disk 45. By rotating the cleaning disk 481, the elastic brush 485 can be driven to rotate, and the elastic brush 485 can be used to brush the grinding debris scraped by the scraper 484, so that the grinding debris is brushed away.
[0033] There are four elastic strips 483, and the four elastic strips 483 are evenly distributed on the top side of the sweeping disc 481. The scraper 484 passes through the sweeping disc 481 and extends to its bottom, and the scraper 484 is slidably installed between the sweeping disc 481 and the sweeping disc 481.
[0034] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 1 to 6 As shown: The rotating mechanism 3 includes a power source 31. The bottom of the power source 31 is fixedly installed to the bottom of the inner cavity of the machine body 1 by screws. A four-jaw chuck 32 is fixedly installed at the output end of the top of the power source 31. A right-angled push rod 33 is hinged to the side of the top of the power source 31. A return spring 34 is fixedly connected between the inner side of the right-angled push rod 33 and the top of the power source 31. A striking ball 35 is rolled on the top of the right-angled push rod 33. When the operator rotates the right-angled push rod 33 counterclockwise, the striking ball 35 moves away from the top of the four-jaw chuck 32, and the return spring 34 is stretched. This makes it easier for the four-jaw chuck 32 to clamp and fix the concrete block that needs to be tested for wear resistance. The power source 31 provides power, and the output end of the power source 31 drives the four-jaw chuck 32 to rotate, causing the concrete block to rotate as well. The direction of rotation of the concrete block is opposite to the direction of rotation of the grinding ball head 47, which improves the grinding efficiency of the grinding ball head 47 on the concrete block.
[0035] The reset spring 34 is installed at an angle, the striking ball 35 is hollow, and the striking ball 35 is installed directly above the four-jaw chuck 32.
[0036] As the grinding ball head 47 and the sweeping disc 481 move downwards together, and the bottom of the grinding ball head 47 contacts the top of the concrete block, the right-angled top rod 33 can be released. Under the elastic tension of the reset spring 34, the right-angled top rod 33 drives the striking ball 35 to rotate clockwise for reset. As the sweeping disc 481 rotates, the top edge of the scraper 484 contacts the striking ball 35, causing the striking ball 35 to be subjected to an upward pushing force. The reset spring 34 is stretched again. As the scraper 484 continues to rotate, the scraper 484 separates from the striking ball 35. Under the elastic tension of the reset spring 34, the right-angled top rod 33 drives the striking ball 35 to rotate in the opposite direction. The striking ball 35 strikes the sweeping disc 481, causing the sweeping disc 481 to vibrate. Under the action of vibration, dust and debris fall off the scraper 484 and the elastic brush 485.
[0037] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 1 to 8 As shown: A dust removal mechanism 5 is fixedly installed on the bottom of the surface of the body 1. The dust removal mechanism 5 includes a water tank 51. The surface of the water tank 51 is fixedly installed on the bottom of the surface of the body 1. An air outlet 52 is fixedly installed on the side of the top of the water tank 51. A drain pipe 53 is fixedly installed on the side of the bottom of the water tank 51. A suction fan 54 is fixedly installed on the side of the top of the inner cavity of the water tank 51. A J-shaped air guide plate 55 is fixedly connected to the middle of the inner cavity of the water tank 51. A partition plate 56 is fixedly connected to the surface of the J-shaped air guide plate 55 and the side away from the suction fan 54. The partition plate 56 is installed at an angle. A ventilation hole 57 is opened on the top of the surface of the partition plate 56.
[0038] The staff turns on the suction fan 54 to operate. The suction generated by the suction fan 54's air inlet absorbs the dust and debris brushed away by the elastic brush 485. The air outlet of the suction fan 54 applies a blowing force between the J-shaped air guide plate 55 and the inside of the water tank 51. The pressure difference causes the water level to slowly drop until a narrow gap appears between the bottom of the J-shaped air guide plate 55 and the bottom of the inner cavity of the water tank 51. This allows dusty air to enter the water between the J-shaped air guide plate 55 and the partition plate 56. The water is turbulent under the airflow, and water splashes everywhere, allowing the air and water to come into full contact. The water carries away the dust and debris, forming a water vortex for dust removal, while the air passes through the vent hole 57 and is discharged from the air outlet 52, thus achieving dust suppression.
[0039] There are two water tanks 51, and the two water tanks 51 are symmetrically installed along the central axis in the middle of the body 1. The bottom of the air outlet 52 is connected to the water tank 51, and the air vents 57 are evenly distributed on the top of the surface of the partition 56.
[0040] When in use, the staff first injects an appropriate amount of water into the water tank 51 from the air outlet 52, so that the water level exceeds the bottom of the J-shaped air guide plate 55 and the partition plate 56. At this time, the right-angle top rod 33 is rotated counterclockwise, so that the striking ball 35 is moved away from the top of the four-jaw chuck 32, and the reset spring 34 is stretched, so that the four-jaw chuck 32 can clamp and fix the concrete block that needs to be tested for wear resistance. The operator starts the hydraulic cylinder 41 to work. By extending the telescopic end of the hydraulic cylinder 41, the plate 42 can be moved downward, thereby moving the rotating shaft 43 and the servo motor 44 together. This allows the grinding ball head 47 to move downward along with the rotating shaft 43, making it easy to adjust the height of the grinding ball head 47. As the grinding ball head 47 and the cleaning disc 481 move downward together, and the bottom of the grinding ball head 47 contacts the top of the concrete block, the right-angle top rod 33 can be released. Under the elastic tension of the reset spring 34, the right-angle top rod 33 drives the striking ball 35 to rotate clockwise to reset. The striking ball 35 is on the top of the cleaning disc 481. Power source 31 is used as the power source. The output end of power source 31 drives the four-jaw chuck 32 to rotate, causing the concrete block to rotate together. Servo motor 44 is started to work. The rotation of the output end of servo motor 44 can drive the toothed turntable 45 to rotate. The right angle tooth 46 is engaged with the tooth on the surface of the toothed turntable 45, so that the right angle tooth 46 is subjected to a pulling force. With the support of the rotating shaft 43 by the plate 42 and the right angle tooth 46 installed below the plate 42, the rotating shaft 43 can drive the grinding ball head 47 to rotate smoothly without shaking. This makes it easy for the grinding ball head 47 to grind the concrete block to be tested stably. The rotation direction of the concrete block is opposite to the rotation direction of the grinding ball head 47, which improves the grinding efficiency of the grinding ball head 47 on the concrete block. Furthermore, the output end of the servo motor 44 drives the toothed turntable 45 to rotate, and the top of the connecting rod 482 is engaged with the teeth on the surface of the toothed turntable 45, so that the connecting rod 482 is subjected to the pulling force of the toothed turntable 45, and under the rotation support of the rotating shaft 43, the toothed turntable 45 rotates, and the rotation direction of the toothed turntable 45 is opposite to the rotation direction of the grinding ball head 47. The bottom of the scraper 484 is in contact with the top of the concrete block. As the scraper 484 rotates, the grinding debris discharged from the grinding ball head 47 can be scraped. As the scraper 484 continues to rotate in a circular motion, the grinding debris is guided by the scraper 484 to move outward, and the grinding debris is initially scraped off. At the same time, the rotation of the cleaning disc 481 can drive the elastic brush 485 to rotate, so that the elastic brush 485 can brush the grinding debris scraped by the scraper 484, and the grinding debris can be brushed away. Furthermore, the staff turns on the suction fan 54 to operate, using the suction force generated by the suction port of the suction fan 54 to absorb the dust and debris brushed off by the elastic brush 485. The air outlet of the suction fan 54 applies a blowing force between the J-shaped air guide plate 55 and the inside of the water tank 51, creating a pressure difference that causes the water level to slowly drop until a narrow gap appears between the bottom of the J-shaped air guide plate 55 and the bottom of the inner cavity of the water tank 51. This allows dust-laden air to enter the water body between the J-shaped air guide plate 55 and the partition plate 56. The water body is turbulent under the blowing of the airflow, splashing water everywhere, which allows the air and water body to come into full contact. The water body carries away the dust and debris, forming a water vortex for dust removal, while the gas passes through the vent hole 57 and is discharged from the air outlet 52, thus achieving dust suppression.
