Description

Technical Field

[0002] Soil sampling in geological exploration is a basic and critical task that helps determine the physical and chemical properties of the soil and whether there is mineralization. Soil sampling is usually divided into two categories: collecting surface samples and collecting soil profile samples.

[0003] Chinese patent CN216082127U discloses a soil stratification rapid sampling device for engineering geological survey, including a driving device. The soil stratification rapid sampling device for engineering geological survey described in the utility model can extract the sampled soil in layers through the detachable material collection bucket, arc base, connector, arc mounting cover, scale, threaded ring and detachable soil breaking head, avoiding squeezing the soil to ensure the accuracy of soil stratification, and the supporting frame including a circular fixed plate, a rotating shaft, a supporting rod, a circular base and a fixing nail can be arranged to vertically fix the sampling device to ensure the stability and verticality of the sampling, thereby avoiding the influence of the sampling tilt on the detection result, and reducing the work intensity of the user, and the whole soil stratification rapid sampling device for engineering geological survey has a simple structure, and the device is not only simple in structure, but also easy to operate, bringing better prospects for use.

[0004] In the above patent, when encountering more complex terrain, such as uneven terrain, it is necessary to manually use tools to level the ground to ensure the use of the support frame, which is time-consuming and labor-intensive. The uneven ground causes the support frame to be unable to adapt to the terrain, resulting in the inability to ensure that the sampling device is vertically fixed, which in turn affects the test results. It can be seen that the support frame used by the sampling device has a small scope of application. Utility Model Content
