Description

Technical Field

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

[0002] Coal mine geological drilling refers to a geological project that uses certain drilling machinery and technology to obtain coal samples below the surface to make reliable evaluations of geological and mineral resource parameters. Before mining, deep sampling of the geology of the coal mine location must be carried out, so relevant staff often use coal mine geological deep sampling devices;

[0003] A Chinese patent publication (publication number: CN217033117U) discloses a deep sampling device for coal mine geological exploration, which includes a sampling barrel, a drill rod, a fixing plate, a limiting ring, a fixing sleeve, a conical drill bit, a through hole and a sampling assembly. The sampling assembly is detachably placed in the sampling barrel, a connecting ring is placed on the edge of one end of the sampling barrel, and the connecting ring and the fixing plate are fixedly connected by multiple bolts. One side of the fixing plate is connected to the drill rod, a limiting ring is built into the sampling barrel, and the edge of the limiting ring is connected to the inner wall of the sampling barrel. The other end of the sampling barrel is connected to the conical drill bit, and a through hole is opened in the conical drill bit. The fixing sleeve is placed on the inner wall of the other end of the sampling barrel, and the fixing sleeve is connected to the through hole in the conical drill bit; initially, the spiral rod extends into the through hole. The drill rod is connected to the drilling rig, and the sampling device is drilled into the deep sampling position of the geological stratum of the coal mine through the drilling rig. After drilling to the specified depth, the rotating motor is started, which drives the spiral rod to rotate. At the same time, the pneumatic telescopic rod slowly extends and pushes the connecting slide plate to move toward the conical drill bit, so that the spiral rod leaves the through hole and drills into the deep sampling position. The spiral blades on the spiral rod break the stratum through the rotation of the spiral rod, and at the same time drive the deep coal mine sample to be transported to the sampling barrel for sampling. When the connecting slide plate contacts the limit ring, the rotating motor is reversed to make the spiral rod rotate back into the sampling barrel. After the sampling is completed, the reverse drilling rig removes the sampling device from the stratum, then removes the fixing plate, and removes the sampling assembly at the same time, and then pours out the coal mine sample in the sampling barrel for collection. However, in actual use, after sampling, the fixing plate needs to be removed and the sampling assembly needs to be taken out before the coal mine sample in the sampling tube can be poured out and collected, which is time-consuming and laborious. After each sampling, the sample needs to be disassembled to take out the sample, and then it needs to be installed again before sampling can continue, which reduces the sampling efficiency and is not conducive to sampling. Therefore, it is currently necessary to propose a geological deep sampling device to achieve the effect of convenient sampling. Utility Model Content
