AI Technical Summary
Existing insertion sampling devices are prone to damage during use, and the extracted soil is scattered, making it impossible to effectively determine the specific layers of the soil, resulting in poor detection results.
A soil sampling device was designed, comprising a handle, a first sampling tube, a second sampling tube, a motor, a screw, a screw sleeve, a connecting rod, and a clamping block. The motor drives the screw to rotate, which in turn raises the second sampling tube. The clamping block and clamping groove work together to separate the sampling tube, facilitating observation of the soil conditions at different levels. The soil is then quickly discharged through a push plate and a through-hole structure.
It enables efficient observation and rapid removal of soil samples, improves sampling efficiency and detection efficiency, prevents damage to the sampler and soil dispersion, and ensures detection accuracy.
