[0016] Preferably, a second mounting seat is further provided on the machine body. The second mounting seat is located at the outlet of the conveyor belt. A second spray pipe is provided on the second mounting seat. The second spray pipe is connected to the first spray pipe, and multiple spray heads on the second spray pipe face the outlet of the conveyor belt.

[0017] By adopting the above technical solution, the second spray pipe is set to spray and treat the dust at the outlet of the conveyor belt to prevent dust from flying during the transportation of sand and gravel.

[0018] Preferably, a shielding pad is provided at the bottom of the second mounting seat, and the shielding pad is located on the side of the outlet of the conveyor belt away from the screening area.

[0019] By adopting the above technical solution, the shielding plate can block the splashing of the sand and gravel conveyed from the outlet of the conveyor belt and protect the staff.

[0020] Preferably, a sponge pad is provided on the surface of the shielding pad facing the conveyor belt, and the sponge pad is located on the spraying path of the second spray pipe.

[0021] By adopting the above technical solution, the sponge pad can suck dust and cooperate with the second spray pipe to suppress dust. At the same time, the water mist sprayed by the second spray pipe will clean the sponge, so that the dust attached to the sponge pad is washed away, ensuring the continuous dust suction performance of the sponge pad.
