Description

A portable drilling device for geological prospecting Technical Field

[0001] The present invention relates to the technical field of geological prospecting, and in particular to a portable drilling device for geological prospecting. Background Art

[0002] Geological prospecting refers to the geological prospecting projects carried out inside and outside the production mining area to increase new gold reserves, extend the service life of the mine, and further identify the geological structure and hydrogeology. The geological prospecting process often requires drilling and soil sampling, and in-depth research and preparation work are required for specific areas to provide a solid foundation for subsequent geological exploration and mineral resource assessment.

[0003] The existing geological prospecting drilling devices are generally large and fixed, not convenient to carry, and most of them are one-piece designs that cannot be folded and stored, which brings great pressure to subsequent transportation, movement, and carrying. Therefore, there are limitations. When sampling in prospecting projects, the sampling device is generally placed in the corresponding depth of the borehole to take samples. After taking samples, the device is taken out and then placed in another depth in the borehole to take samples. Multiple samplings are required to achieve sampling at different depths. The operation is cumbersome, time-consuming and labor-intensive, which increases the workload of the staff. At the same time, the machine is used frequently, which increases the cost investment. It is impossible to sample different depths in the borehole at the same time. When the drilling machine is taken out after drilling, the drilled soil is easy to fall into the hole and cannot be accurately sampled, so the sampling value has a large error.
