AI Technical Summary

Technical Problem

In existing technologies, the water film on the surface of damp grains increases friction and adhesion, causing the grains to easily stick to the edge of the screen and accumulate, resulting in blockage of the sorting frame. Moreover, cleaning requires disassembling the screens one by one, which is cumbersome.

Method used

A screening device for grain processing was designed, equipped with a cleaning mechanism. A motor drives a threaded rod to move a sliding block, and a jet pipe sprays water to remove adhering grains. Combined with an opening mechanism, it provides cleaning space and avoids manual disassembly of the screen.

Benefits of technology

It enables the removal of screen blockages without manual disassembly, improving screening efficiency, simplifying the cleaning process, and ensuring the continuity of screening operations.
