AI Technical Summary

⚠Technical Problem

There are problems such as screen hole blockage, low screening efficiency and poor equipment reliability in the screening process of lunar soil, especially in the in-situ application of lunar soil screening equipment, it is difficult to achieve high-precision screening and stable equipment operation.

⚗Method used

The in-situ lunar soil screening mechanism adopts centrifugal vibrating stirring brush. Through the vibration of the inner screen assembly and the rotation of the brush head assembly, the alternating current is used to adsorb lunar dust. Combined with the spiral support and connecting rod structure, screening and discharge are achieved, avoiding clogging and improving screening efficiency.

🎯Benefits of technology

This effectively prevents screen clogging, reduces dust generation, improves screening efficiency and equipment reliability, and ensures efficient screening and smooth discharge of lunar soil.
