Description

Technical Field

[0001] This utility model relates to the field of core sampling technology, and more specifically, to a core sampling device for geological prospecting and exploration. Background Technology

[0002] A core is a cylindrical rock sample extracted from a borehole using a ring core drill bit and other coring tools, as needed for geological exploration or engineering work. Ore-bearing rocks or ore extracted from the ore body or ore layer of a solid mineral deposit are called ore cores. Cores are crucial physical geological data for studying and understanding underground geology and mineral resources. During mineral exploration and development, drilling work is carried out according to the stratigraphic level and depth designed geologically, and coring tools are lowered into the well to extract rock samples. Cores are the most direct and practical data for understanding underground strata and ore-bearing characteristics.

[0003] Patent CN218512056U discloses a core sampling device for geological prospecting, including a motor housing. A motor is fixedly installed inside the motor housing, and a transmission rod is splined to the output end of the motor. An auxiliary telescopic rod is fixedly connected to one end of the transmission rod, and a main telescopic rod is sleeved on the outer surface of the auxiliary telescopic rod. A blade cylinder is fixedly connected to the bottom of the main telescopic rod. This patent, through the arrangement of the auxiliary telescopic rod, main telescopic rod, and blade cylinder, allows for adjustment of the sampling device's height, facilitating core sampling. The motor rotation drives the blade cylinder to rotate, cutting the core, which is easy for personnel to operate. Bolts and baffles facilitate core removal, preventing the core from getting stuck in the blade cylinder, thus avoiding interference with personnel work and reducing efficiency. The A and B belt pulleys and threaded rod allow the blade cylinder to move up and down for cutting, improving convenience. However, in actual operation, the continuous rotation of the blade cylinder generates a large amount of dust, which can affect the work of surrounding personnel. Utility Model Content
