[0021] Reference Figure 1-6When the equipment is running, the engine 3 on the base 1 first drives the hydraulic pump 4. The hydraulic pump 4 converts the mechanical energy of the engine 3 into hydraulic energy, which drives the lifting wheels 6.

The rotation of gear 53 drives the slewing support 51 to rotate. The rotation of slewing support 51 drives the turntable fixing frame 49 to rotate. The turntable fixing frame 49 adjusts the fog cannon component 64 to a suitable position. At this time, the electric push rod 56 runs to adjust the nozzle of the fog cannon component 64. The centrifugal pump 54 runs to pump water from the water tank 55 into the nozzle ring component 66 inside the fog cannon component 64, and sprays it out through the nozzle 106 on the nozzle ring component 66 to carry out dust suppression.
