AI Technical Summary

Technical Problem

Existing soil sampling devices are prone to leaving soil residue on their inner walls after use, leading to contamination of subsequent samples and inaccurate test results.

Method used

A biological crust soil sampling device was designed, comprising a top plate, a sampling cylinder, a connecting column, a cleaning mechanism, and a fixing mechanism. The sampling cylinder is driven to move up and down by a second pressing plate, and the inner wall soil is cleaned by a shovel. The device is fixed by nails and side plates to ensure sampling accuracy and cleaning convenience.

Benefits of technology

This allows for convenient cleaning of the soil inside the sampling tube after sampling, avoiding sample contamination, ensuring the accuracy of sampling results and the stability of the device, and simplifying the cleaning process.
