AI Technical Summary
Existing stratified sampling devices are cumbersome to operate, requiring manual twisting of the collection tube and its automatic return to its original position. Furthermore, the sample must be poured into a container after each sampling, which reduces sampling efficiency.
A stratified sampling device was designed, which adopted a sampling outer tube, an inner tube and a torsion spring structure. The inner tube automatically returned to its original position to close the sampling port through the elastic force of the torsion spring, and the collection structure was used to achieve rapid sample collection and multi-point sampling.
The operation process has been simplified, making sampling faster and improving sampling efficiency. The collection structure enables rapid collection and multi-point sampling of samples.
