Description

Technical Field

[0001] The present application relates to the field of coal mine geological survey, and in particular, to a deep sampling device for coal mine geological survey. Background Art

[0002] Coal is mainly formed by Mesozoic trees being buried in the soil and undergoing long periods of changes underground. When exploring for coal mines, people must first analyze whether there are Jurassic or Carboniferous terrestrial coal-bearing strata in an area, and then drill some exploratory wells on the ground. By taking out rock cores, they can directly see the depth of the coal seam, how thick it is, and whether it has mining value. In the process of coal mining, sampling and testing are also required inside the coal mine tunnels.

[0003] The structure of the product can refer to a deep sampling device for coal mine geological survey disclosed in Chinese patent document 202121901502.3, which belongs to the technical field of survey equipment, including a first installation box, and a second installation box located on one side of the first installation box, the first installation box is provided with a first connecting seat inside, and the second installation box is provided with a second connecting seat on the back, and the first installation box and the second installation box are rotatably connected through the first connecting seat and the second connecting seat. The utility model can adjust the inclination angle of the sampling tube and the ground by adjusting the angle between the first installation box and the second installation box through the arrangement of the first installation box, the second installation box, the first connecting seat and the second connecting seat, so that the sampling tube can be drilled and sampled at multiple angles. Through the arrangement of the push piece and the through hole, an iron rod can be inserted through the through hole at the end of drilling to push the push piece downward, so that all the coal seam samples inside the coupling are ejected, and the coal seam samples can be better taken out as a whole, which is convenient for later detection.

[0004] However, in this patent, the sampling tube is not convenient to be inserted into the mineral soil during sampling and testing, which may damage the sampling tube and reduce its practicality.
