[0016] 2. In the utility model, when water is circulated, dust in the water is settled inside the collection box at the bottom of the No. 1 overflow chamber and the No. 2 overflow chamber. When a certain amount of precipitated dust is collected inside the collection box, the servo motor is turned on to drive the adjusting screw to rotate, so that the threaded sleeve moves upward along the adjusting screw, thereby driving the collection box to move upward, which is convenient for cleaning the dust collected inside the collection box.

[0017] 3. In the utility model, the position of the support plate is adjusted by rotating the connecting bolt rotating shaft through the connecting outer tube, and the support plate is moved to a position where it can support the ground. At this time, the connecting nut is tightened to deform the connecting outer tube by squeezing the base to squeeze and fix it, thereby positioning the support plate. Then the threaded support rod is rotated to support the support plate with the ground. The height of the support plate from the bottom of the connecting inner tube can be adjusted by adjusting the number of rotations of the threaded support rods at the four corners of the base, so that the device can be stably placed on an uneven ground, avoiding the tilt of the base placement position due to the uneven ground inside the base mine, resulting in unstable placement of the device as a whole.

[0018] 4. In the utility model, according to the height of the dust generated at the working place, the height of the No. 1 mounting frame can be adjusted by the telescopic electro-hydraulic push rod. By adjusting the height of the No. 1 mounting frame, the height of the dust reduction mechanism can be adjusted, so that the dust at different height layers can be accurately, quickly and fully reduced. When the No. 1 mounting frame moves up and down, the No. 1 mounting frame drives the slider to slide along the slide rail, and the No. 1 mounting frame is limited by the slide rail and the slider, so as to improve the stability of the No. 1 mounting frame when it moves up and down.

[0041] The effect achieved by the entire embodiment is that the device is placed as a whole at a dust-generating operation site, and according to the size and shape of the ground on which it is placed, the position of the support plate 112 is adjusted by rotating the connecting bolt 17 through the connecting outer tube 19, and the support plate 112 is moved to a position where it can be supported by the ground. At this time, the connecting nut 18 is tightened to deform the base 11 to squeeze and fix the connecting outer tube 19, thereby positioning the position of the support plate 112, and then the threaded support rod 111 is rotated to support the support plate 112 with the ground, and the threaded support rod 111 is adjusted by adjusting the four corners of the base 11.

[0045] When performing dust reduction operations, after the height adjustment of the dust reduction mechanism 2 is completed, water is added to the processing pool 32, and the circulation pump 212 and the ventilation motor 25 are turned on at the same time. At this time, the ventilation motor 25 drives the fan blades 26 to rotate, and the external dust is sucked into the dust reduction box 22. The circulation pump 212 extracts the water in the processing pool 32 through the pumping pipe 213, and then passes it into the diversion water tank 28 through the water supply pipe 216. At this time, the diversion water tank 28 distributes the water to the inside of each spray pipe 29, and then the atomizing nozzle 210 sprays it to the dust reduction box 2 2, the dust inside is subjected to dust reduction operation, the water adsorbing the dust is collected by the water collecting bucket 27, and then passed into the No. 1 overflow cavity 38 inside the treatment pool 32 through the guide pipe 214, and after a first sedimentation inside the No. 1 overflow cavity 38, it flows into the No. 2 overflow cavity 39 through the overflow hole on the surface of the No. 1 overflow plate 36 for secondary sedimentation, and the dust collected in the water is fully precipitated, and then enters the water supply cavity 310 through the overflow hole on the surface of the No. 2 overflow plate 37, and is then pumped out by the circulation pump 212 for recycling;

[0046] When water is circulated, dust in the water is deposited inside the collection box 311 at the bottom of the No. 1 overflow chamber 38 and the No. 2 overflow chamber 39. When a certain amount of precipitated dust is collected inside the collection box 311, the servo motor 34 is turned on to drive the adjusting screw 35 to rotate, so that the threaded sleeve 312 moves upward along the adjusting screw 35, thereby driving the collection box 311 to move upward.

[0047] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields.
