Description

Technical Field

[0001] The utility model relates to the technical field of geological survey, in particular to a sampling device for geological survey. Background Art

[0002] At present, there is a large demand for shallow drilling sampling in the fields of geological survey, geochemical prospecting, geophysical prospecting, basic engineering survey, etc. Geological survey plays an extremely important role in studying the regional environment and the changes in the regional environment. There is a need for a lightweight geological survey sampling drill that can be carried by manpower. The portable geological survey sampling drill is a small and lightweight sampling drilling equipment mainly suitable for mountainous areas, transportation and energy inconvenient areas. The use of this drill can replace traditional manual excavation, trenching and well exploration sampling. It can not only speed up the sampling work, but also greatly reduce the damage to vegetation and protect the environment. It is an indispensable technical means for shallow geological exploration work such as regional geological mapping, geophysical and geochemical sampling, paleomagnetic sampling, and geological disaster prevention.

[0003] The existing sampling devices for geological surveys have certain drawbacks when used. First, the sampling effect of the existing sampling devices is not ideal, and the collection and preservation of soil samples cannot be completed simultaneously, causing secondary damage to the original structural characteristics and mechanical properties of the soil samples. Secondly, the existing sampling devices for geological surveys are prone to unstable fixation during operation. The support frame of the existing sampling device is prone to tilting on one side due to unstable force during operation, affecting the normal progress of the sampling work. Finally, the existing sampling devices for geological surveys are not only difficult to carry due to their large size, but also costly, which has a certain impact on people's use process. For this reason, we propose a sampling device for geological surveys. Utility Model Content
