Description

Technical Field

[0001] The utility model relates to the technical field of vibration screening machinery, in particular to a vibration screen feeding back plate. Background Art

[0002] Vibrating screens are widely used in the grading, dehydration, desludging and de-intermediation of materials in the mineral processing and coal preparation industries. During operation, the materials to be screened enter the screen surface through the feed end of the screen machine and are discharged after screening. In this process, all parts of the screen machine are involved in vibrations to varying degrees. Compared with other parts, the feed end is the first and most directly subjected to long-term and concentrated stamping of the material. It has a large dynamic stress and is one of the weakest parts of the vibrating screen. Fractures and feed end deflection often occur during use. Therefore, the vibrating screen is equipped with a supporting and reinforcing member at the feed end. Existing vibrating screens mostly use a feed end beam connection structure. However, its processing and manufacturing are relatively complex and costly. And when applied to multi-layer screens, the sealing effect is not good. Utility Model Content
