Sampling device for in-situ geological survey
By designing components such as threaded connecting sleeves and limiting rings, the problem of difficulty in removing soil samples caused by their tight adhesion to the inner wall of the soil sampler was solved, enabling convenient removal of soil samples and improving sampling efficiency.

AI Technical Summary
Existing sampling devices for geological exploration are cumbersome to operate when extracting soil samples, and the samples are tightly attached to the inner wall of the sampler, which increases the difficulty of extraction.
The system employs components such as threaded connecting sleeves, limiting rings, compression blocks, and separation structures. Through threaded connection and limiting design, it ensures a stable connection between the drill rod and the threaded connecting sleeve. Furthermore, through the inclined design of the isolation plate and the cooperation of the elastic block, it achieves a stable separation between the isolation plate and the inner wall of the drill rod, facilitating the removal of soil samples.
It simplifies the process of extracting soil samples, reduces operational difficulty, and improves sampling efficiency.
