Soil layer sampling device for geological exploration

Abstract

The invention belongs to the field of geological prospecting, and particularly discloses a soil layer sampling device for geological prospecting. The device comprises a sampling barrel. A rotating shaft is rotatably connected in the sampling barrel, a plurality of groups of stirring assemblies are arranged on the rotating shaft from top to bottom, and a plurality of groups of sampling assemblies are arranged on the outer wall of the sampling barrel from top to bottom. The stirring assembly comprises a stirring rod rotationally connected to the rotating shaft and transversely arranged and stirring blades hinged to the rotating shaft and located below the stirring rod. Driving bevel gears are fixed to the portions, located above the stirring rod, of the rotating shaft, and a connecting rod is rotationally connected to the inner wall of the sampling barrel. A driven bevel gear meshed with the driving bevel gear is fixed to the connecting rod, a through hole allowing the connecting rod toextend out is formed in the sampling barrel and located in the connecting rod, and the inner diameter of the through hole is larger than the outer diameter of the connecting rod. Spiral blades are fixed at the part, outside the sampling barrel, of the connecting rod. By the adoption of the scheme, the problem that it is troublesome to complete sampling of soil layers of different depths through multiple times of sampling of a sampler can be solved.

Description

technical field [0001] The invention belongs to the field of geological exploration, and in particular relates to a soil layer sampling device for geological exploration. Background technique [0002] As we all know, the environment of each place is different, and the soil environment brought by it will also be different, and the composition, structure, and water content of the soil will also be different. Soil analysis is the qualitative and quantitative determination of soil components and their physical and chemical properties. It is the basic work of soil formation and development, fertility evolution, soil resource evaluation, soil improvement and rational fertilization research. important means of quality assessment. Especially in geological exploration, the analysis of soil layers at different depths is extremely necessary. The commonly used sampling analysis methods include mixed analysis and single-point analysis. Mixed analysis means to analyze the mixed soil laye...
