The motor 3 is started to drive the rotating shaft 9 and the stirring rod 10 to rotate, so that the sand and gravel are evenly spread on the first screen 11, and the larger sand and gravel remain on the top first screen 11, and the smaller sand and gravel fall on the bottom first screen 11. After the screening is completed, the micro servo motor is started to drive the rotating rod 18 to rotate, thereby driving the baffle 19 to rotate, so that the top ends of the first discharge pipe 4 and the second discharge pipe 5 are opened, and the sand and gravel after screening are transported through the first discharge pipe 4 and the second discharge pipe 5 and fall on the two conveyor belts 7 for transportation, so as to prevent the screened sand and gravel from piling up.

[0022] A water collecting trough 13 is provided at the bottom of the inner wall of the box body 1, and a second screen 12 is provided between the inner walls of the water collecting trough 13. A pump body 15 is fixedly connected to the rear side of the box body 1, and the input and output ends of the pump body 15 are fixedly connected to the water supply pipe 14. The top of the top water supply pipe 14 passes through the box body 1 and is fixedly connected to a circular pipe 16, and the circular pipe 16 passes through and is fixedly connected to the box body 1. The bottom of the circular pipe 16 passes through and is fixedly connected with a uniformly distributed atomizing nozzle 17. At the same time, during screening, the pump body 15 starts to extract the water stored in the water collecting trough 13, and then transports it to the circular pipe 16.

At the same time, when screening, the pump body 15 starts to extract the water stored in the water collection tank 13, and then transports it to the circular pipe 16, and then the atomizing nozzle 17 on the circular pipe 16 atomizes and sprays the water, so as to reduce the dust generated by the sand and gravel during screening and reduce the impact of the dust on the staff and the working environment. The water that is washed down passes through the second screen. The filtered particles 12 fall back into the water collection tank 13 for recycling. After the screening is completed, the micro servo motor is started to drive the rotating rod 18 to rotate, thereby driving the baffle 19 to rotate, so that the top ends of the first discharge pipe 4 and the second discharge pipe 5 are opened, and the screened sand and gravel are transported through the first discharge pipe 4 and the second discharge pipe 5 and fall on the two conveyor belts 7 for transportation, preventing the screened sand and gravel from piling up.
