During the movement of the semi-arc block 505, the semi-arc block 505 will contact the push block 1 509, and the semi-arc block 505 will continue to rise. At this time, the push block 1 509 will squeeze and push the semi-arc block 505, so that the semi-arc block 505 is centered on the hinge column 1 504, and the semi-arc block 505 is angularly offset downward. The rotation of the semi-arc block 505 will drive the atomizing nozzle 506 to rotate. When the booster disk 503 moves downward, The booster disk 503 drives the hinge column 1 504 to move, and the movement of the hinge column 1 504 will also drive the semi-arc block 505 to move downward. During the downward movement of the semi-arc block 505, the semi-arc block 505 will contact the push block 2 511, and the push block 2 511 will squeeze and push the semi-arc block 505 to rotate upward by a certain angle. The angle deviation of the atomizing nozzle 506 can increase the area of ​​the sprayed water mist and increase the dust reduction range. It can effectively control the spray direction and distribution range of the water mist and increase the contact area between the water mist and the dust in the air.

[0018] When the device is used, the motor 8 will start, and the output end of the motor 8 will drive the reciprocating screw 501 to rotate, and the reciprocating screw 501 will drive the booster plate 503 to move up and down reciprocatingly, and the reciprocating up and down movement of the booster plate 503 will drive the block 601 to move up and down reciprocatingly, and during the reciprocating up and down movement of the block 601, the block 601 will come into contact with the rotating column 604 and squeeze and push the rotating column 604, so that the rotating column 604 rotates around the support 603, and the rotation of the rotating column 604 squeezes the spring block 602, and the rotating column 604 During the rotation process, the moving plate 605 will also be driven to move, and the movement of the moving plate 605 will drive the push plate 606 to move, and the movement of the push plate 606 will push the water dripping on the surface of the inclined box 10 to move. When the extrusion force on the rotating column 604 ends, the spring block 602 will reset and drive the rotating column 604 to reset. After the rotating column 604 is reset, it will knock on the surface of the inclined box 10, causing the inclined box 10 to vibrate to a certain extent, thereby increasing the speed at which the water on the surface of the inclined box 10 reaches the collection point, and can guide the dripping water, thereby improving the subsequent collection. The speed is improved, and the efficiency of the device is improved. At the same time, the rotation of the reciprocating screw 501 will drive the protrusion 1 502 to rotate. During the rotation of the protrusion 1 502, the protrusion 1 502 will contact the protrusion 2 612 and squeeze and push the protrusion 2 612. The movement of the protrusion 2 612 will drive the collection box 607 to move. The movement of the collection box 607 will squeeze the telescopic end of the elastic telescopic rod 1 608. At the same time, the movement of the elastic telescopic rod 1 608 will drive the L plate 1 609 to move. The movement of the L plate 1 609 will drive the sealing block 610 to move. The sealing block The movement of 610 will open the opening of the inclined box 10, and the water dripping from the surface of the inclined box 10 can fall into the inside of the collecting box 607 through the opening of the inclined box 10. When the protrusion 1 502 is no longer in contact with the protrusion 2 612, the elastic telescopic rod 1 608 will reset and drive the collecting box 607 to reset. At this time, the water in the collecting box 607 will pass through the filter plate 611 and then re-enter the inside of the water tank 4. The filtered water can be used again, which can reduce the construction cost, save water resources, improve the use capacity of the device, and reduce the cost of the device when in use.
