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 with the support 603 as the center. The rotation of the rotating column 604 will squeeze the spring block 602. During the rotation process, the rotating column 604 will also drive the moving plate 1 605 to move. The movement of the moving plate 1 605 will drive the push plate 606 to move. The movement of the push plate 606 will push the water dripping on the surface of the inclined box 10 to move. When the squeezing 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 improving the inclined box.

At the same time, the rotation of the reciprocating screw 501 drives the protrusion 1 502 to rotate. During the rotation of the protrusion 1 502, the protrusion 1 502 contacts the protrusion 2 612 and squeezes and pushes the protrusion 2 612. The movement of the protrusion 2 612 drives the collection box 607 to move. The movement of the collection box 607 squeezes the telescopic end of the elastic telescopic rod 1 608. At the same time, the movement of the elastic telescopic rod 1 608 drives the L plate 1 609 to move. The movement of the L plate 1 609 drives the sealing block 610 to move. The movement of the sealing block 610 opens the opening of the inclined box 10.Water dripping from the surface of the inclined box 10 can fall into the interior of the collection box 607 through the opening of the inclined box 10. When the first protrusion 502 and the second protrusion 612 are no longer in contact, the elastic telescopic rod 1 608 will reset and drive the collection box 607 back to its original position. At this time, the water inside the collection box 607 will pass through the filter plate 611 and re-enter the interior of the water tank 4. The filtered water can be reused, which can reduce construction costs, save water resources, improve the usability of the device, and reduce the cost of the device during use.

The output end of the motor 8 will drive the reciprocating screw 501 to rotate, and the rotation of the reciprocating screw 501 will drive the protrusion 502 to rotate. At the same time, the rotation of the reciprocating screw 501 will also drive the booster disc 503 to rotate, but the booster disc 503 is limited by the limiting column 507 at this time, so the booster disc 503 can only move up and down through the reciprocating groove on the surface of the reciprocating screw 501. The up and down reciprocating movement will drive the hinge column 504 to move, the movement of the hinge column 504 will drive the semi-arc block 505 to move, the movement of the semi-arc block 505 will drive the atomizing nozzle 506 to move, the up and down movement of the atomizing nozzle 506 can adapt to different heights, increase the dust reduction range of the atomizing nozzle 506, the water mist sprayed by the atomizing nozzle 506 can cover the dust at higher places, improve the use efficiency of the device, and increase the dust prevention effect of the device.

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, causing the semi-arc block 505 to deviate downward at an angle. 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 hinged column 1 504 to move, and the movement of the hinged 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 offset of the atomizing nozzle 506 can increase the area of the sprayed water mist, increase the dust reduction range, 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.
[0026] When the device is used, the motor 8 is started, and the output end of the motor 8 drives the reciprocating screw 501 to rotate, and the reciprocating screw 501 drives the boost disk 503 to move up and down reciprocatingly, and the reciprocating up and down movement of the boost disk 503 drives the block 601 to move up and down reciprocatingly, and the block 601 contacts the rotating column 604 during the reciprocating up and down movement and squeezes and pushes the rotating column 604, so that the rotating column 604 rotates with the support 603 as the center, 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.

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, which can guide the dripping water and improve the subsequent collection Speed, improve the efficiency of the device, 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 come into contact with 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, and 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.
