AI Technical Summary
In current concrete production, screens are easily damaged by stones getting stuck, and manual knocking on the screens can also cause damage.
A screening device for concrete production raw materials was designed, which includes a screening mechanism and a vibration mechanism. The eccentric wheel driven by the motor drives the movable plate to swing, thereby causing the screen to vibrate and forcing the stuck stones to fall off.
This effectively avoids damage caused by manual tapping of the screen, and improves the service life and screening efficiency of the screen.
