AI Technical Summary
In existing multi-stage vibrating screens, the lowest screen chamber is prone to loosening or deformation at the connection with the main body of the vibrating screen due to excessive load, resulting in a high damage rate.
A support base and a positioning screw are installed on the top of the side wall of the vibrating screen body, and a positioning clamp is installed at the bottom of the side wall of the screen chamber. The clamp is fixed to the positioning screw by a locking device to form an auxiliary support structure and reduce the concentration of load on the screen chamber.
This improves the protective effect of the screen chamber, preventing loosening or deformation damage caused by vibration and excessive load, and enhancing the stability and service life of the screen chamber.
