AI Technical Summary
The existing drum screen has a fixed support frame, making it difficult to adjust the drum's inclination angle, which makes it difficult to meet the material screening requirements under different working conditions.
By rotatably connecting one end of the support frame to the fixed frame, and using an adjusting component at the other end to adjust the angle between the support frame and the fixed frame, the roller tilt angle can be flexibly adjusted.
It enables flexible adjustment of the drum tilt angle under different working conditions, improves the applicability of material screening and the stability of the equipment, prevents screw loosening, and improves screening efficiency and equipment performance.
