AI Technical Summary
Existing soil sample screening devices for soil remediation testing suffer from problems such as small vibration frequency amplitude, poor screening effect, and poor locking stability due to loose limit nuts during the vibration screening process.
A cyclic vibration-assisted screening mechanism and a compaction mechanism are adopted. Multiple screening sleeves are vibrated and compacted by electric drive, which increases the vibration amplitude and improves the locking stability.
It improves the stability and efficiency of screening, reduces the loosening and separation of the sleeve during the screening process, and enhances the effect of vibrating screening.
