Abstract

The invention discloses a soil layer sampling device for geological exploration. The device comprises a rack, wherein a sampling rod is arranged in the middle of the rack; a spiral blade is welded onthe periphery of the lower side of the sampling rod; a bearing block is arranged on the upper side of the rack, a driving mechanism is mounted on the bearing block, a plurality of springs are arrangedbetween the bearing block and the rack, crank levers are hinged to two ends of the bearing block, and the other ends of the crank levers are correspondingly hinged to two ends of the rack; drill bitsare arranged at the lower end of the sampling rod, a sampling assembly is mounted on the inner side of the lower end of the sampling rod, a sampling piston is arranged on the inner side of the sampling assembly, a limiting cavity is formed in the sampling rod on the upper side of the sampling assembly, a limiting piston is glidingly arranged in the limiting cavity in a matched manner, and a buffer cavity is formed in the sampling rod on the upper side of the limiting cavity. During use, the soil layer sampling device is higher in stability and can reduce bending torsion received by the device, the working efficiency of the device is improved, the service life of the device is prolonged, the sampling effect is good, and guarantee is provided for soil layer sampling operation.

Description

technical field [0001] The invention relates to the field of geological exploration, in particular to a soil layer sampling device for geological exploration. Background technique [0002] "Geological prospecting" is the investigation and research activity of conducting geological exploration and detection through various means and methods, determining the appropriate bearing layer, determining the foundation type and calculating the foundation parameters according to the foundation bearing capacity of the bearing layer. It is the discovery of mineral deposits with industrial significance in the general survey of mineral resources. In order to ascertain the quality and quantity of mineral products, as well as the technical conditions for mining and utilization, provide mineral reserves and geological data required for mine construction design, and analyze rocks and strata in a certain area. Conduct investigation and research work on geological conditions such as geology, str...
