The linkage mechanism 5 is located between adjacent distribution pipes 13. Two dust concentration detectors 9 symmetrically arranged in an upper and lower manner are provided on the inner wall of the box body 1. A valve 7 is provided on the side wall of the box body 1. The setting of the valve 7 can efficiently and quickly realize the cleaning of the box body 1 and the discharge of the cleaned sewage, thereby improving the convenience of cleaning.

[0026] Specifically, the driving mechanism 6 is started, and the two threaded rods 25 are driven by the driving mechanism 6 to rotate synchronously. Synchronously, the two fans 21 are driven to rise and fall while blowing air into the box 1, ensuring that the wind direction will not always remain in a consistent direction during the blowing process, thereby improving the authenticity of the simulated real environment, and cooperating with the linkage effect to promote the movement of the linkage mechanism 5 in the discharge pipe 12 at the bottom of the inhibitor barrel 3, which can effectively control the discharge amount of the dust suppressant and the requirements for automatic discharge, reduce the labor of manual discharge, and the discharge amount is uniform, which can improve the accuracy of the detection data.

[0027] The blower mechanism 2 includes a blower 21, a limit block 22, a fixed frame 23, a limit bar 24 and a threaded rod 25. The blower 21 is movably connected in the slide grooves on both sides of the box body 1, the limit block 22 is connected to the side wall of the blower 21, the fixed frame 23 is connected to the side wall of the box body 1, the limit bar 24 is vertically connected in the fixed frame 23, the threaded rod 25 is vertically rotatably connected in the fixed frame 23, the threaded rod 25 is threadedly connected to the blower 21, and the thread directions of the two threaded rods 25 are oppositely set. Through the lifting and lowering movement of the blower 21, the blowing position in the box body 1 can be adjusted, and the actual blowing state in actual transportation can be restored to ensure the accuracy of data testing.

[0028] The trigger mechanism 4 includes a contact block 41 and a sleeve 42. The contact block 41 is slidably connected to the inner top wall of the box body 1.

The head ends of the two stoppers 51 are connected to racks 53. The two racks 53 slide through the mounting block 54. The mounting block 54 is connected to the box body 1. On the inner top wall, a gear 55 is meshed between the two racks 53, and the gear 55 is rotatably connected to the inner wall of the box body 1. The tail ends of the two stop blocks 51 are provided with a bar 52. The right end of one mounting block 54 is connected to the contact block 41, and the other mounting block 54 is movably inserted in the sleeve 42, which ensures the quantitative feeding of the dust suppressant and avoids the situation where the feeding amount cannot be accurately controlled during manual feeding. The feeding is achieved by linkage, which can effectively reduce the workload of manual labor and improve production efficiency.

[0029] The sealing assembly 10 includes a spring 101 and a corrugated sealing strip 102. The head ends of the spring 101 and the corrugated sealing strip 102 are connected to the inner wall of the slide groove, and the tail ends of the spring 101 and the corrugated sealing strip 102 are commonly connected to the adjacent fan 21, which can ensure the sealing of the side wall of the box body 1 when the fan 21 is in motion, and prevent the particles in the box body 1 from being blown to the outside of the box body 1 when blowing, causing pollution to the air environment outside the equipment.

[0030] A driving mechanism 6 capable of driving the two blower mechanisms 2 to move up and down is provided at the bottom of the box body 1. A support seat 8 is provided at the bottom of the driving mechanism 6. The power output shaft of the driving mechanism 6 is connected to the threaded rod 25 through a belt, which drives the two threaded rods 25 to rotate synchronously in the same direction, thereby improving the efficiency of the equipment operation.

[0031] The practical working principle of the present invention is as follows: first, the driving mechanism 6 is started, and the two threaded rods 25 are driven to rotate through the power output shaft of the driving mechanism 6. The interaction between the threads and the limiting effect of the limit strip 24 on the fan 21 make the threaded rod 25 drive the fan 21 to move up and down when it rotates. When the blower mechanism 2 drives the push block 11 to move to the top of the box body 1, the push block 11 fits with the contact block 41. Through the fitting contact of the inclined surface, the push block 11 pushes the contact block 41 to move toward the head end. The two blocks 51 are connected by the meshing of the gear 55 and move synchronously in opposite directions. When one of the blocks 51 is located between two adjacent feed pipes 13, the other block 51 leaves the current position. Such reciprocating movement can realize quantitative feeding of the dust suppressant. The dust concentration detector 9 is started to monitor the dust concentration in the box body 1 in real time. During cleaning, the flushing water flows through the cleaning setting at the bottom of the box body 1. After accumulating in the direction of the valve 7, the accumulated water in the box body 1 is manually discharged.
