When grabbing materials, if the dust is large, the staff can start the water pump 2, extract the water source in the water tank 3 through the water pump 2, and transport it to the secondary transfer box 6 through the primary pipe 4, and then the secondary transfer box 6 is directed to two three-level branch boxes 9, and one of the two three-level branch boxes 9 is connected to its direct nozzle 13, and the other three-level branch box 9 is connected to its atomizing nozzle 14. At this time, the staff only needs to control the corresponding solenoid valve 7 to quickly control its direct nozzle 13 or atomizing nozzle 14, and spray water through the direct nozzle 13 and the atomizing nozzle 14, so as to perform dust reduction operations. Among them, the two solenoid valves 7 and the water pump 2 are controlled by the foot pedal, which will not affect the operation of the staff.
