Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a building wall grinding device with a dust suction function. Background Art

[0002] In the grinding operation of building walls, the grinding device is usually equipped with a suction device to reduce the escape of dust. However, the existing suction device has the problem of low efficiency, resulting in a large amount of dust still spreading into the air. This phenomenon not only deteriorates the working environment, but also poses a serious threat to the health of workers. Dust particles are suspended in the air and are easily inhaled by workers. Long-term exposure may cause respiratory diseases and other occupational diseases.

[0003] In addition, the spread of dust will affect visibility at the construction site, reduce work efficiency, and may even cause safety accidents. Summary of the invention

[0004] In order to overcome the problem of low efficiency of existing suction devices, which causes a large amount of dust to still diffuse into the air, the present invention provides a building wall grinding device with a dust suction function.

[0005] The technical solution of the present invention is: a building wall grinding device with a dust suction function, comprising a cover shell; also comprising a connecting seat, a driving motor, a connecting pipe, a grinding disc, a baffle, a breathable cloth sheet, an air bag, an annular tube, a water pipe, a nozzle, a DD motor, an arc plate, bristles and a suction pipe; the cover shell is fixedly connected with a connecting seat; the connecting seat is equipped with a driving motor; the rotating part of the driving motor is connected with a connecting pipe; the connecting pipe is fixedly connected with a grinding disc; a plurality of baffles are fixedly connected with the cover shell; a plurality of breathable cloth sheets are fixedly connected with the cover shell; all baffles and the breathable cloth sheets are fixedly connected with an air bag; the connecting seat is fixedly connected with an annular tube; a plurality of water pipes are fixedly connected and connected with the annular tube, and all the water pipes are located in the wall of the cover shell; each water pipe is fixedly connected and connected with a plurality of nozzles; the connecting seat is fixedly connected with a DD motor; the rotating part of the DD motor is connected with an arc plate, and the arc plate is fitted with the cover shell; one of the baffles is fixedly connected with a suction pipe, and the suction pipe is connected with the inside of the cover shell.

[0006] More preferably, all the baffles and breathable fabrics are arranged in a staggered manner.

[0007] More preferably, a plurality of straight grooves are provided at the bottom of the grinding disc.

[0008] More preferably, all the nozzles protrude from the inner surface of the housing, and all the nozzles are made of deformable rubber material.

[0009] More preferably, a scraper is also included; a scraper is fixedly connected to both sides of the arc plate, all scrapers are in contact with the baffle and the breathable cloth, and the side of the scraper facing the baffle and the breathable cloth is hollow, and each scraper is provided with a water outlet.

[0010] More preferably, bristles are further included; and the hollow portion of each scraper is fixedly connected with bristles.

[0012] More preferably, the surface of the airbag is provided with a wear-resistant layer.

[0013] More preferably, the breathable fabric sheet is coated with a waterproof coating.

[0014] More preferably, the cover is made of transparent material.

[0015] Beneficial effect: The present invention arranges straight grooves at the bottom of the grinding disc so that the dust from grinding flows into the water mist sprayed from the nozzle through the straight grooves, so that the dust and the water mist are quickly combined. At the same time, the external pump is controlled to blow the outside air in through the connecting pipe, so that the air is sprayed out from the straight grooves at the bottom of the grinding disc, which speeds up the combination of dust and water mist.

[0016] The present invention squeezes the nozzle by an arc plate, so that the nozzle bends and deforms. When the nozzle bends and deforms, the dirt at the nozzle outlet is also deformed accordingly and becomes easier to fall off. When the arc plate squeezes the nozzle, the space inside the nozzle gradually becomes smaller, so that the water pressure gradually increases, so that the dirt blocking the nozzle outlet is flushed away.

[0017] The present invention forms a relatively closed space between the cover shell and the arc plate, so that the water mist sprayed from the nozzle is quickly condensed into a small water flow, so that when the small water flow passes through the scraper, it flushes the bristles and dilutes the dirt adhered to the bristles. At the same time, after the small water flow flows out from the water outlet, it passes through the surface of the baffle and the breathable cloth sheet, and at the same time, the dirt adhered to the surface of the baffle and the breathable cloth sheet is flushed and diluted, which facilitates the cleaning of the bristles and improves the cleaning effect.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment 1: A building wall polishing device with dust collection function, such as Figure 1-Figure 5 As shown, it includes a cover 1; It also includes a connecting seat 2, a driving motor 3, a connecting pipe 4, a grinding disc 5, a baffle 6, a breathable cloth piece 7, an air bag 8, a ring pipe 9, a water pipe 10, a nozzle 11, a DD motor 12, an arc plate 13, bristles 14 and a suction pipe 15; the cover 1 is fixedly connected to the connecting seat 2; the driving motor 3 is bolted to the connecting seat 2; the rotating part of the driving motor 3 is connected to the connecting pipe 4; the connecting pipe 4 is fixedly connected to the grinding disc 5; six baffles 6 distributed in an annular manner are fixedly connected to the cover 1; six breathable cloth pieces distributed in an annular manner are fixedly connected to the cover 1 7; an air bag 8 is fixedly connected to all the baffles 6 and the breathable cloth piece 7; an annular tube 9 is fixedly connected to the connecting seat 2; a plurality of water pipes 10 are fixedly connected to and connected to the annular tube 9, and all the water pipes 10 are located in the wall of the cover shell 1; each water pipe 10 is fixedly connected to and connected to a plurality of nozzles 11; a DD motor 12 is bolted to the connecting seat 2; the rotating part of the DD motor 12 is connected to an arc plate 13, and the arc plate 13 is fitted with the cover shell 1; a suction pipe 15 is fixedly connected to one of the baffles 6, and the suction pipe 15 is connected to the inside of the cover shell 1.

[0022] All the baffles 6 and the breathable fabric pieces 7 are arranged in a staggered manner. By arranging the baffles 6 and the breathable fabric pieces 7 in a staggered manner, it is ensured that air is ejected from the breathable fabric pieces 7 .

[0023] A plurality of straight grooves 501 are formed at the bottom of the grinding disc 5, so that the dust produced by grinding flows into the water mist sprayed from the nozzle 11 through the straight grooves 501, thereby quickly combining the dust with the water mist.

[0024] All the nozzles 11 protrude from the inner surface of the cover shell 1, and all the nozzles 11 are made of deformable rubber material. By making all the nozzles 11 protrude from the inner surface of the cover shell 1, when the arc plate 13 passes through the nozzle 11, the arc plate 13 squeezes the nozzle 11, causing the nozzle 11 to bend and deform. When the nozzle 11 bends and deforms, the dirt at the nozzle opening of the nozzle 11 also deforms accordingly, making it easier to fall off, and when the arc plate 13 squeezes the nozzle 11, the space inside the nozzle 11 gradually becomes smaller, thereby gradually increasing the water pressure, so that the dirt blocked at the nozzle opening of the nozzle 11 is flushed away, further improving the cleaning effect.

[0025] It also includes a scraper 16; a scraper 16 is fixedly connected to both sides of the arc plate 13, all scrapers 16 are in contact with the baffle 6 and the breathable cloth sheet 7, and the side of the scraper 16 facing the baffle 6 and the breathable cloth sheet 7 is hollow, and each scraper 16 is provided with a water outlet 1601.

[0026] Bristles 14 are also included; the bristles 14 are fixedly connected to the hollow space of each scraper 16.

[0027] The side of the arc plate 13 facing the cover shell 1 is hollow. When the arc plate 13 rotates and the nozzle 11 is located in the hollow position, the arc plate 13 is in close contact with the cover shell 1. Therefore, the cover shell 1 and the arc plate 13 form a small space together. At this time, the water mist sprayed by the nozzle 11 quickly condenses into a small water flow, so that when the small water flow passes through the scraper 16, it flushes the bristles 14 and dilutes the dirt adhered to the bristles 14. At the same time, after the small water flow flows out from the water outlet 1601, it will pass through the surface of the baffle 6 and the breathable cloth sheet 7, and at the same time, the dirt adhered to the surface of the baffle 6 and the breathable cloth sheet 7 will be flushed and diluted, which is convenient for cleaning the bristles 14 and improves the cleaning effect.

[0028] During operation, first connect the corresponding grip rod to the rotating disc bolt on the connecting seat 2, then connect the suction pipe 15 to the external suction device, then manually hold the grip rod to fit the cover 1, grinding disc 5, baffle 6, breathable cloth piece 7 and air bag 8 to the wall, then control the drive motor 3 to drive the connecting pipe 4 and the grinding disc 5 to rotate, so that the grinding disc 5 grinds the wall, and at the same time manually swing the grip rod to make the grinding disc 5 evenly grind the wall, and at the same time, control the external suction device to suck away the dust generated by the grinding disc 5.

[0029] Considering that there is a lot of dust when grinding the wall, the efficiency of sucking the dust only by the external suction device is low, which will cause some dust to remain in the cover 1. When the handle is swung manually to move the grinding disc 5, the dust will overflow from the cover 1 and float in the air. After the workers inhale the dust, it will affect their health. Therefore, the external water pump is connected to the water inlet on the annular pipe 9, and then the external water pump is controlled to pump water into the annular pipe 9 and the water pipe 10, and water mist is sprayed through the nozzle 11, so that the water mist moistens the wall surface, and at the same time, the dust generated by grinding is adsorbed by the water mist to form clumping debris, which is then blown away along the air bag. The arc surface of 8 flows downward to the suction pipe 15 and is sucked away, thereby avoiding the problem of dust overflowing from the cover 1, and a plurality of straight grooves 501 are arranged at the bottom of the grinding disc 5, so that the dust polished down flows into the water mist sprayed from the nozzle 11 through the straight grooves 501, so that the dust and the water mist are quickly combined. At the same time, by connecting the connecting pipe 4 to an external pump, the external pump is controlled to blow outside air through the connecting pipe 4, so that the air is sprayed out from the straight grooves 501 at the bottom of the grinding disc 5, which speeds up the combination speed of dust and water mist, and the outside air continues to blow the straight grooves 501 to prevent dust accumulation in the straight grooves 501.

[0030] At the same time, it is considered that when the water mist fills the housing 1, the dust will adhere to the inner surface of the housing 1 to form dirt, causing the dust to adhere and accumulate. Therefore, the DD motor 12 is controlled to drive the arc plate 13 to rotate, so that the arc plate 13 scrapes the inner surface of the housing 1 so that the adhered dirt is scraped off. At the same time, because the water mist and the dust will combine with each other to form dirt, the spray hole on the nozzle 11 is easily blocked, thereby affecting the spray effect. Therefore, by making all the nozzles 11 protrude from the inner surface of the housing 1, when the DD motor 12 When the arc plate 13 is driven to rotate, the arc plate 13 squeezes the nozzle 11, causing the nozzle 11 to bend and deform. When the nozzle 11 bends and deforms, the dirt at the nozzle opening of the nozzle 11 also deforms accordingly and becomes easier to fall off. When the arc plate 13 squeezes the nozzle 11, the space inside the nozzle 11 gradually decreases from large to small, so that the water pressure gradually increases, so that the dirt blocking the nozzle opening of the nozzle 11 is flushed away. At the same time, the surfaces of the baffle 6 and the breathable cloth sheet 7 will also adhere to the dirt. Therefore, when the DD motor 12 continues to drive When the arc plate 13 rotates, the arc plate 13 drives the scraper 16 to rotate, so that the scraper 16 scrapes off the dirt adhered to the surface of the baffle 6 and the breathable cloth sheet 7. At the same time, the scraper 16 is provided with bristles 14, and the bristles 14 also clean the mesh holes on the surface of the breathable cloth sheet 7, further improving the cleaning effect. When the nozzle 11 is located in the hollow position of the arc plate 13, a relatively closed space is formed between the cover 1 and the arc plate 13. At this time, the water mist sprayed by the nozzle 11 quickly condenses into a small water flow, so that the small water flow When passing through the scraper 16, the bristles 14 are flushed to dilute the dirt adhered to the bristles 14. At the same time, the small water flow flows out from the water outlet 1601 and passes through the surface of the baffle 6 and the breathable cloth piece 7. At the same time, the dirt adhered to the surface of the baffle 6 and the breathable cloth piece 7 is flushed and diluted, which is convenient for cleaning the bristles 14 and improves the cleaning effect. By setting the water outlet 1601, the water flow is guided to the surface of the baffle 6 and the breathable cloth piece 7, so that the flushing time of the water flow on the surface of the baffle 6 and the breathable cloth piece 7 is increased, further improving the cleaning effect.

[0031] Embodiment 2: Based on embodiment 1, Figure 1-Figure 4 As shown, a wear-resistant layer is provided on the surface of the airbag 8 to prevent the airbag 8 from directly rubbing against the wall surface, which would lead to a reduction in service life.

[0032] The breathable fabric sheet 7 is coated with a waterproof coating to prevent water from overflowing from the breathable fabric sheet 7 .

[0033] The cover 1 is made of transparent material, and the internal water mist can be manually observed through the cover 1 to adjust the size of the water mist to achieve a better cleaning effect.

[0034] The arc plate 13 is made of wear-resistant material to increase the service life.

[0035] When the grinding disc 5 is grinding the wall, the airbag 8 is in close contact with the wall. When the worker swings the grip to make the grinding disc 5 grind the wall evenly, the airbag 8 will also swing accordingly, causing the airbag 8 to continuously rub against the wall, resulting in a reduction in the service life of the airbag 8. A wear-resistant layer is provided on the surface of the airbag 8 to avoid direct friction between the airbag 8 and the wall, thereby preventing the service life from being reduced. At the same time, a waterproof coating is applied on the breathable cloth sheet 7 to prevent water from overflowing from the breathable cloth sheet 7. The cover shell 1 is set to a transparent material, and the internal water mist is observed manually through the cover shell 1 to adjust the size of the water mist and achieve a better cleaning effect.

[0036] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
