AI Technical Summary
Existing soil moisture measuring devices cannot perform stratified sampling, resulting in soil samples from different depths being mixed together, making accurate detection difficult. Furthermore, soil samples inside the sampling tube are prone to slippage, affecting the accuracy of the measurement results.
A soil moisture content measuring device with stratified sampling capability was designed. It adopts a stratified sampling mechanism, which includes a driving component, a sampling component, and a closing component. The sampling tube is driven to extend by a hydraulic rod and anchored by a high-strength elastic thin steel strip during retraction to prevent soil sample slippage. The stability of the sampling tube is maintained by an electromagnet.
This technology enables independent sampling of soil layers at different depths, ensuring soil sample integrity, improving the accuracy of measurement results and the stability of the device, and reducing operational difficulty.
