Geological exploration sampling device

Abstract

The invention discloses a geological exploration sampling device, and relates to the technical field of geological exploration equipment. Thegeological exploration sampling device comprises a main body, a worm and gear motor, a transmission shaft and a center rod. The first rotating shell and the planetary plate are in idle rotation through the one-way bearing, the first rotating shell and the main gear are fixedly connected, the rotating speed of the planetary plate is lower than that of the main gear, the rotating speed of the planetary plate and the rotating speed of the main gear are not synchronous, and then the multiple sets of planetary gears conduct autorotation; A self-rotating planetary gear drives a reciprocating telescopic mechanism to enable a vertical blade to stretch out and draw back so as to adjust the sampling radius of soil, and when a first rotating shell and a planetary plate are locked through a one-way bearing, the planetary plate and a main gear have the same rotating speed and are synchronous, and the planetary gear is relatively static and does not rotate; The telescopic vertical blade can crush the soil with different radius lengths, and the spiral blades are driven by the center rod to rotate, so that the spiral blades can synchronously lift and discharge the crushed soil upwards.

Description

technical field [0001] The invention relates to the technical field of geological prospecting equipment, in particular to a geological prospecting sampling device. Background technique [0002] Geological exploration can be understood as geological work in a broad sense. It is based on the needs of economic construction, national defense construction, and scientific and technological development, using geological exploration methods such as surveying and mapping, geophysical prospecting, geochemical prospecting, drilling, pit exploration, sampling testing, and geological remote sensing. , Investigation and research work on geological conditions such as rocks, stratum structures, minerals, groundwater, and landforms in a certain area. [0003] Geological exploration requires sampling the surface soil. Soil refers to a layer of loose material on the surface of the earth, which is composed of various granular minerals, organic substances, water, air, microorganisms, etc., and c...
