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

[0002] Coal is a combustible mineral. It is formed by the accumulation of plants buried in the ground over time. Coal is also an essential resource in today's life. The coal exploration sampling device is used to extract samples from underground coal resources for subsequent laboratory analysis to evaluate the quality and characteristics of the coal.

[0003] When the coal exploration geological sampling device is in use, the bottom end of the sampling tube is inserted into the coal geology, and the driving assembly is started to drive the drill bit and the spiral feed blade to rotate and push downward at the same time, so that the coal is transported upward along the spiral feed blade for sampling. After the sampling is completed, it needs to be cleaned, but the spiral feed blade is located in the sampling tube, which makes it easy for soil to adhere to the spiral feed blade and the inner wall of the sampling tube, resulting in a more cumbersome cleaning process and poor cleaning effect. Soil is easy to remain inside, which can easily affect the next coal geological sampling and detection. Therefore, in response to the above problems, we propose a coal exploration geological sampling device. Utility Model Content

When cleaning is required, the nut 11 is rotated outward to remove the nut 11 and the gasket 12, and then the handle 8 is rotated outward. The handle 8 drives the screw assembly 7 to rotate outward, so that the screw assembly 7 is rotated upward along the first internal threaded sleeve 6 and the second internal threaded sleeve 9 and removed. Then the elastic steel plate assembly 3 is removed to separate the sampling tube 1, the spiral feeding blade 15 and the drill bit 19, and then clean them separately, so that the cleaning is cleaner and the soil residue is reduced, so that the next coal geological sampling test results are more accurate. The installation can be carried out by reverse operation. The installation and disassembly process is simple, which makes cleaning easier.
