Technical field

The utility model relates to the field of geological sampling devices, specifically a rock sampling device.

Background technique

Field geological exploration is an investigation and research activity that uses various means and methods to survey and detect the geology, determine the appropriate bearing layer, determine the foundation type and calculate the foundation parameters based on the foundation bearing capacity of the bearing layer. Mineral deposits of industrial significance are discovered during the mineral survey. In order to ascertain the quality and quantity of minerals, as well as the technical conditions for mining and utilization, provide mineral reserves and geological data required for mine construction design, and analyze the rocks and strata in a certain area. Conduct investigation and research on geological conditions such as structures, minerals, hydrology, and landforms.

Drilling sampling refers to an exploration method that uses a drill to drill holes in the formation to identify and divide the subsurface strata and to sample along the depth of the hole. Drilling is the most widely used exploration method in engineering geological survey, which can obtain deep geological data. When sampling rock samples, a handheld backpack drill is used. The handheld backpack drill has the advantages of small size, easy operation, and portability. It has been widely used when sampling rock samples.
