The phenomenon of blockage of the discharge port can be avoided. When the screw 11 rotates, it drives the turntable 10 to rotate. The two turntables 10 rotate synchronously through the belt, thereby driving the transmission shaft 15 to rotate. The transmission shaft 15 drives the two eccentric wheels 18 to rotate. The rotation of the two eccentric wheels 18 and the use of the spring 13 can make the filter frame 14 vibrate up and down in the slide 17, which helps to filter the water used for dust reduction. The filtered sewage is discharged from the water outlet, and the wetted stones are discharged from the discharge port.
