Description

Technical Field

[0001] The utility model relates to a deep sampling device for coal mine geological exploration, belonging to the technical field of mine geological exploration equipment. Background Art

[0002] Coal is the primary solid fuel and a type of combustible organic rock. It is formed by the natural coalification of lush vegetation that grew over a period of geological time, gradually accumulating into thick layers in a suitable geological environment and then being buried in water or mud. Before mining can begin, deep sampling of the geology of the mine site is necessary, and deep sampling devices are often used.

[0003] According to the authorized patent CN213688980U, the utility model in this patent is provided with a sampling assembly inside the sampling box. After drilling into the deep geological layer of the coal mine, the sample is located inside the sampling tube, which can prevent the sample from being contaminated by the outside world, reduce the work intensity of the staff, and facilitate the exploration work. However, when replacing the drill bit and the sampling tube, the drill bit needs to be disassembled and then the sampling tube needs to be installed, which wastes a lot of time. At the same time, vibration will be generated during drilling, and gravel will fall on the surface of the equipment, which needs to be cleaned up later. Utility Model Content
