The blasting dust removal device is composed of a water tank, a high-pressure water pump, a water pipe, and a high-pressure nozzle installed on a vehicle body. When using the blasting dust removal device for dust removal in a small area, the vehicle body is driven to a point farther away from the blasting point, the high-pressure water pump is started, so that the water source passes through the water pipe and finally sprays out from the high-pressure nozzle, forming a water curtain above the blasting point.

The water pipe 5 is fixedly connected to the water tank 1. The upper end of the water pipe 5 is fixedly connected to a high-pressure spray head 6. An auxiliary dust removal assembly 2 is arranged on the right side of the water tank 1.
[0029] Referring to Figure 2 and Figure 3 As shown in the figure, in this implementation: The auxiliary dust removal assembly 2 includes a collection box 21 detachably connected to the vehicle body. The upper end of the collection box 21 is detachably connected to a lid 22. The upper end of the lid 22 is fixedly connected to a first collection pipe 23. A collection hopper 25 is fixedly connected to the arc surface of the first collection pipe 23. A collection net 24 is detachably connected to the inner wall of the collection box 21. A negative pressure mechanism 26 is arranged at the bottom of the inner wall of the collection box 21. By setting the auxiliary dust removal assembly 2, when it is necessary to assist in removing dust generated by blasting, the first collection pipe 23 is surrounded around the blasting area, and at the same time, the first collection pipe 23 is kept within a safe range from the blasting area. When the dust generated after blasting rises upward, it is blocked by the water curtain sprayed by the high-pressure spray head 6. At the same time, under the action of the negative pressure mechanism 26, the collection hopper 25 on the first collection pipe 23 on the lid 22 has suction, so that the dust that escapes to the surroundings is sucked in and thus is sucked into the collection net 24 in the collection box 21, thereby achieving the function of reducing dust for the dust that escapes to the surroundings after blasting as much as possible. The negative pressure mechanism 26 includes an installation groove 261 opened at the bottom of the inner wall of the collection box 21. An installation frame 262 is fixedly connected to the inner wall of the installation groove 261. The lower end of the installation frame 262 is rotatably connected to an impeller 263. Through a driving mechanism, the impeller 263 on the installation frame 262 in the installation groove 261 rotates at a high speed, so that a negative pressure area is formed in the collection box 21, and thus the collection hopper 25 on the first collection pipe 23 on the lid 22 has suction. The lower end of the impeller 263 is fixedly connected to a first bevel gear 267. A second bevel gear 266 is meshed and connected to one side of the first bevel gear 267. A water turbine 264 is arranged on the inner wall of the water pipe 5. A rotating shaft 265 is rotatably connected to the arc surface of the water pipe 5. The rotating shaft 265 is rotatably connected to the collection box 21. The second bevel gear 266 is fixed to the rotating shaft 265. When the high-pressure water pump 4 works, water is sucked into the water pipe 5, so that when the water turbine 264 has water flowing through it, it is driven to rotate at a high speed, thereby driving the rotating shaft 265 to rotate. Then, through the transmission of the first bevel gear 267 and the second bevel gear 266, the impeller 263 rotates. A fixing ring 268 is fixedly connected to the arc surface of the first collection pipe 23. A positioning rod 269 is threadedly connected to the lower end of the arc surface of the fixing ring 268. By driving the positioning rod 269 on the fixing ring 268 into the ground, the first collection pipe 23 is fixed.
[0030] Referring to Figure 3 and Figure 4As shown in the figure, in this embodiment: A connection component 3 is provided on one side of the first collecting pipe 23. The connection component 3 includes a second collecting pipe 31 provided on one side of the first collecting pipe 23. The other end of the second collecting pipe 31 is closed. When it is necessary to increase the length of the collecting pipe, the second collecting pipe 31 and the first collecting pipe 23 are fixed through a fixing mechanism, thereby increasing the length of the collecting pipe. A sliding ring 32 is slidably connected to the arc surfaces of the first collecting pipe 23 and the second collecting pipe 31. Insert pins 33 are slidably inserted into both sides of the inner arc surface of the sliding ring 32. The insert pins 33 are inserted into the first collecting pipe 23 and the second collecting pipe 31. The sliding ring 32 is dragged so that the left insert pin 33 is snapped into the first collecting pipe 23, and then the second collecting pipe 31 is dragged so that the right insert pin is snapped into the second collecting pipe 31, thereby fixing the second collecting pipe 31 and the first collecting pipe 23. A spring 34 is fixedly connected between the insert pin 33 and the sliding ring 32. A sealing ring 36 is provided between the sliding ring 32 and the first collecting pipe 23 and the second collecting pipe 31. By providing the spring 34, the insert pin 33 is reset. A pull rope 35 is fixedly connected to the upper end of the insert pin 33. The pull rope 35 passes through the sliding ring 32, and pulling the pull rope 35 causes the insert pin 33 to move.
[0031] Working principle:
[0032] When using the blasting dust removal device for small-scale blasting dust removal, the vehicle body is driven to a point far away from the blasting point, and the high-pressure water pump 4 is started, so that the water source in the water tank 1 passes through the water pipe 5 and is finally sprayed out by the high-pressure nozzle 6 to form a water curtain above the blasting point, thereby blocking the dust generated by the blasting. At the same time, the water combines with the dust and falls to the ground, thereby achieving dust removal. When it is necessary to assist in dust removal of the dust generated by the blasting, the collecting pipe 1 23 is surrounded along the blasting area, and the collecting pipe 1 23 and the blasting area are kept in a safe range. When the dust generated after the blasting is lifted up, it is blocked by the water curtain sprayed by the high-pressure nozzle 6. At the same time, when the high-pressure water pump 4 is working, water is sucked into the water pipe 5, so that when water flows through the water turbine 264, it is driven to rotate at high speed, thereby driving the rotating shaft 265 to rotate, and then through the transmission of the bevel gear 1 267 and the bevel gear 2 266, the impeller 263 rotates, thereby forming a negative pressure area in the collecting box 21 Domain, thereby making the collecting bucket 25 on the collecting tube 1 23 on the cover 22 have suction force, so that the dust generated to escape to the surroundings is sucked into the collecting net 24 in the collecting box 21, thereby achieving the effect of reducing the dust that escapes to the surroundings after blasting as much as possible, and the positioning rod 269 on the fixing ring 268 is nailed into the ground, thereby fixing the collecting tube 1 23. When it is necessary to increase the length of the collecting tube, the left side plug 33 is inserted into the collecting tube 1 23 by dragging the slip ring 32, and then the collecting tube 2 31 is dragged so that the right side plug is inserted into the collecting tube 2 31, thereby fixing the collecting tube 2 31 and the collecting tube 1 23, fixing the collecting tube 2 31 and the collecting tube 1 23, thereby increasing the length of the collecting tube, and sealing the collecting tube 2 31, the collecting tube 1 23 and the slip ring 32 by the sealing ring 36, and the spring 34 is set to reset the plug 33, and the pull rope 35 is pulled to move the plug 33.
