AI Technical Summary
The existing hydrogeological sampling device cannot effectively ensure the verticality of the sampling parts during soil sampling, resulting in an angular deviation when the sampling part penetrates deep into the soil, and the soil samples in the target area cannot be collected, affecting the analysis accuracy. At the same time, existing devices require greater force when sampling in deep layers, and exerting force on a single arm cannot meet the demand.
A hydrogeological sampling device is designed, including a bonding ring block, a sampling rod, a linkage rod, a first screw and a bar-type level. Through the linked insertion and limiting structure of the linkage rod and the first screw, the sampling rod remains vertical during deep soil. At the same time, using the combined structure connecting the semi-arc shell and the fixed snap ring, two modes can be switched according to the depth requirement and the user's force state to meet the needs of deep sampling.
It effectively ensures the perpendicularity of the sampling parts, avoids angular deviations in the sampling parts inside the soil, and improves detection accuracy. At the same time, through the coordination of the auxiliary pedal and screw, it can be switched according to the depth requirements and the user's force state, meeting the needs of deep sampling and improving sampling efficiency.
