The inspection door 12 is hinged to the front of the protection box 2 through a hinge. The hinge itself has a certain load-bearing capacity, which can ensure the normal opening and closing of the inspection door 12 and extend the service life of the inspection door 12. An adjustment mechanism 3 that penetrates to the outside of the protection box 2 and is used to adjust the inclination angle of the device is fixed to the inner bottom wall of the protection box 2, and a movable box 4 is fixed to the left side of the adjustment mechanism 3. A water spray assembly is fixed to the left side of the box body 1, and the water spray assembly can remove dust in the air. The water spray assembly includes a stabilizing plate fixed to the left side of the box body 1, and a stabilizing plate is fixed to the left side of the box body 1. A water tank 5 is fixed on the top of the fixed plate, and a water pump 6 that penetrates into the inner cavity of the water tank 5 is fixed on the top of the water tank 5. A water pipe 7 is connected between the water outlet of the water pump 6 and the diversion pipe 9. A fixed plate 8 is fixed between the top wall and the bottom wall of the inner cavity of the movable box 4. The fixed plate 8 can play the role of fixing the diversion pipe 9. When the movable box 4 is driven to adjust the angle, the diversion pipe 9 can be driven to adjust the angle at the same time. A diversion pipe 9 that penetrates the fixed plate 8 and is used to increase the spraying range is fixed on the fixed plate 8. Several nozzles are fixed on the left side of the diversion pipe 9. A single water outlet can be increased to multiple through the diversion pipe 9, thereby increasing the spraying range, which not only saves working time, but also improves the efficiency of dust reduction, saves time and effort, and an installation hole compatible with the diversion pipe 9 is opened on the left side of the movable box 4.

[0024] In this embodiment, after the movable box 4 and the internal structure of the movable box 4 are adjusted to a suitable spraying angle through the adjusting mechanism 3, the water is transported to the diversion pipe 9 by the water pump 6 for large-scale spraying, thereby achieving the effect of dust reduction and achieving the purpose of adjustable spraying angle.

[0025] See also Figure 3-4 In order to achieve the purpose of adjustable spraying angle, the adjustment mechanism 3 in this embodiment includes a servo motor 301 fixed to the inner bottom wall of the protection box 2, a mounting bracket is fixed to the outer surface of the servo motor 301, the servo motor 301 is fixed to the inner bottom wall of the protection box 2 through the mounting bracket, the output shaft of the servo motor 301 is fixed with a driving gear 302, the inner bottom wall of the protection box 2 is fixed with a transmission assembly 303 located on the left side of the servo motor 301, and the outer surface of the transmission assembly 303 is fixed with a driven gear 304 meshing with the driving gear 302.

[0026] It should be noted that the transmission assembly 303 is composed of two stabilizing blocks 3031, a rotating rod 3032 and two connecting blocks 3033. The two stabilizing blocks 3031 are fixed to the inner bottom wall of the protective box 2 and are distributed front and back. The rotating rod 3032 is rotatably connected between the two stabilizing blocks 3031. Limiting plates are fixed on the front and rear sides of the rotating rod 3032. The limiting plates can limit the rotating rod 3032 to prevent the rotating rod 3032 from gradually moving out of the stabilizing block 3031 during the rotation process, so that the device cannot operate normally. The two connecting blocks 3033 are fixed to the outer surface of the rotating rod 3032 and are fixed to the right side of the movable box 4. A movable hole for the two connecting blocks 3033 to swing is opened on the left side of the protective box 2.

[0027] In this embodiment, the driving gear 302 drives the driven gear 304 to rotate relatively, drives the rotating rod 3032 to rotate, and drives the movable box 4 to adjust to a suitable spraying angle to spray and reduce dust, thereby achieving the purpose of adjustable spraying angle.

[0028] The working principle of the above embodiment is:

[0029] After the device is moved as a whole to the location where dust reduction is required, the servo motor 301 is started. The output shaft of the servo motor 301 rotates while driving the driving gear 302 to rotate. At this time, the driving gear 302 will mesh with the driven gear 304, so that the driving gear 302 and the driven gear 304 rotate relative to each other. At this time, the rotating rod 3032 is driven to rotate by the driven gear 304. The rotating rod 3032 rotates while driving the two connecting blocks 3033 to swing diagonally upward. At the same time, the movable box 4 is also driven to adjust the angle. When it swings to a suitable angle, the servo motor 301 is turned off, and then the water pump 6 is started. The water pump 6 draws the water out of the water tank 5 and transports it to the water pipe 7, and then transports it to the diversion pipe 9 for diversion, and finally sprays it into the air through the nozzle, mixes with the dust to reduce dust, thereby achieving the purpose of adjustable spraying angle and better dust reduction effect.
