[0025] Such as Figures 1 to 4As shown in the figure, an air dust reduction device for air blasting according to an embodiment of the present utility model includes a sleeve 1; a water delivery ring 11 is fixedly connected to the end of the sleeve 1; a plurality of nozzles 111 are communicated with the water delivery ring 11; a first hose 112 is communicated with the inner side of the water delivery ring 11; a first fixing rod 123 is fixedly connected to the inner wall of the sleeve 1; the first fixing rod 123 is provided in plurality on the inner wall of the sleeve 1; a double-output motor 121 is fixedly connected to the end of the first fixing rod 123; a fan 12 is fixedly connected to the front output end of the double-output motor 121; a protective cover 13 is fixedly connected to the end of the sleeve 1; the protective cover 13 is provided with a plurality of holes; a fixing bracket 14 is fixedly connected to the outer side of the sleeve 1; a water pump 15 is fixedly connected below the fixing bracket 14; the end of the first hose 112 is communicated with the water pump 15; during operation, when it is necessary to reduce dust in the surrounding air during blasting, first turn on the water pump 15, the water flow is delivered to the water delivery ring 11 through the first hose 112, and then passes through the nozzles 111. The nozzles 111 spray water mist. At the same time, turn on the double-output motor 121. The front output end of the double-output motor 121 drives the fan 12 to rotate. The strong wind formed by the rapid rotation of the fan 12 drives the water mist, blows the water mist farther, and increases the spraying range. By arranging the protective cover 13 behind the fan 12, the porous setting can not only dissipate heat from the motor, but also reduce the occurrence of secondary pollution caused by the dust generated by external blasting being blown out by the fan 12 while not affecting the air intake of the fan 12. At the same time, it reduces the wear of the fan 12 caused by the dust generated by external blasting and improves the service life of the fan 12.

[0026] As Figures 3 to 4 shown, a second fixing rod 122 is fixedly connected to the rear output end of the double-output motor 121; an inner scraper 2 is arranged at the end of the second fixing rod 122; the inner scraper 2 is attached to the inner wall of the protective cover 13; by arranging the inner scraper 2 on the inner wall of the protective cover 13, when the double-output motor 121 is turned on to drive the second fixing rod 122 to rotate, the second fixing rod 122 drives the inner scraper 2 to rotate, and the dust accumulated on the inner wall of the protective cover 13 can be cleaned, reducing the occurrence of the situation that the protective cover 13 is blocked due to dust caking.

[0027] As Figures 3 to 4 shown, an outer scraper 3 is arranged at the end of the second fixing rod 122; the outer scraper 3 is attached to the outer wall of the protective cover 13; by arranging the outer scraper 3 on the outer wall of the protective cover 13, when the double-output motor 121 is turned on to drive the second fixing rod 122 to rotate, the second fixing rod 122 drives the outer scraper 3 to rotate, and the dust accumulated on the outer wall of the protective cover 13 can be cleaned, reducing the occurrence of the situation that the protective cover 13 is blocked due to dust caking. At the same time, it reduces the occurrence of secondary pollution caused by the dust passing through the protective cover 13 and being blown out by the fan 12, and reduces the wear of the fan 12 caused by the dust generated by external blasting, improving the service life of the fan 12.

[0028] As shown Figures 1 to 5 in the figure, an arc-shaped baffle 4 is fixedly connected to the outside of the water pump 15; the arc-shaped baffle 4 covers the sleeve 1; by arranging the arc-shaped baffle 4 above the sleeve 1, when blasting at the blasting site, the damage and erosion of the stone dust generated by blasting to the surface of the equipment can be reduced, and the service life of the equipment can be prolonged.

[0029] As shown Figures 1 to 5 in the figure, a water delivery pipe 5 is fixedly connected to the top of the arc-shaped baffle 4; the water delivery pipe 5 is provided with openings; a second hose 51 is communicated below the water delivery pipe 5; the end of the second hose 51 is communicated with the water pump 15; by arranging the water delivery pipe 5 at the top of the arc-shaped baffle 4, when there is dust accumulation on the surface of the arc-shaped baffle 4, the water pump 15 can be turned on, the water flow passes through the second hose 51 to reach the water delivery pipe 5, and then flows out through the holes on the water delivery pipe 5, so that the water flow can wash away the dust, keep the arc-shaped baffle 4 clean, and at the same time reduce the corrosion of the dust to the surface of the arc-shaped baffle 4 and prolong the service life of the arc-shaped baffle 4.

[0030] As shown Figures 1 to 6 in the figure, a base 6 is placed below the water pump 15; the water pump 15 is located inside the base 6; by placing the water pump 15 in the base 6, when the water delivery pipe 5 discharges water to wash the arc-shaped baffle 4, the sewage formed after washing can be received, and the pollution of the surrounding environment by the sewage can be reduced.

[0031] Working principle: When it is necessary to reduce dust in the surrounding air during blasting, first turn on the water pump 15. The water flow is conveyed to the water delivery ring 11 through the first hose 112, and then passes through the spray head 111. The spray head 111 sprays water mist. At the same time, turn on the double-output motor 121. The front output end of the double-output motor 121 drives the fan 12 to rotate. The strong wind formed by the rapid rotation of the fan 12 drives the water mist, blowing the water mist farther and increasing the spraying range. By setting a protective cover 13 behind the fan 12, it is possible to reduce the occurrence of secondary pollution caused by the dust generated by external blasting being blown out by the fan 12 while not affecting the air intake of the fan 12. At the same time, it reduces the wear of the fan 12 caused by the dust generated by external blasting. By setting an inner scraper 2 on the inner wall of the protective cover 13, when the double-output motor 121 is turned on to drive the second fixed rod 122 to rotate, the second fixed rod 122 drives the inner scraper 2 to rotate, which can clean the dust accumulated on the inner wall of the protective cover 13. By setting an outer scraper 3 on the outer wall of the protective cover 13, when the double-output motor 121 is turned on to drive the second fixed rod 122 to rotate, the second fixed rod 122 drives the outer scraper 3 to rotate, which can clean the dust accumulated on the outer wall of the protective cover 13, reducing the occurrence of the situation where the protective cover 13 is blocked due to dust caking, and at the same time reducing the occurrence of secondary pollution caused by dust being blown out by the fan 12 through the protective cover 13, and reducing the wear of the fan 12 caused by the dust generated by external blasting. By setting an arc-shaped baffle 4 above the sleeve 1, during the blasting at the blasting site, it can reduce the damage and erosion of the equipment surface caused by the stone dust generated by the blasting. By setting a water delivery pipe 5 on the top of the arc-shaped baffle 4, when there is dust accumulation on the surface of the arc-shaped baffle 4, turn on the water pump 15. The water flow passes through the second hose 51 to reach the water delivery pipe 5 and then flows out through the holes on the water delivery pipe 5, allowing the water flow to wash away the dust, keeping the arc-shaped baffle 4 clean, and at the same time reducing the corrosion of the surface of the arc-shaped baffle 4 by the dust. By placing a base 6 under the water pump 15, when the water delivery pipe 5 discharges water to wash the arc-shaped baffle 4, it can catch the sewage formed after the flushing, reducing the pollution of the surrounding environment by the sewage.
