A sampling device for geological exploration

Abstract

The invention discloses a sampling device for geological exploration, relates to the technical field of geological exploration equipment, and comprises a main body, a worm gear motor, a transmission shaft and a central rod. In the present invention, the first rotating shell and the planetary plate are idling through the one-way bearing, and the first rotating shell and the main gear are fixedly connected. The rotational speed of the planetary plate is lower than that of the main gear and the rotational speed of the planetary plate and the main gear is not Synchronization, and then make multiple sets of planetary gears rotate, and the rotating planetary gears drive the reciprocating telescopic mechanism to expand and contract the vertical blade, thereby adjusting the sampling radius of the soil, and when the first rotating shell and the planetary plate pass through the one-way bearing lock When dead, the rotation speed of the planetary plate and the main gear are the same and synchronized, the planetary gear is relatively stationary and will not rotate, and then the stretched vertical blade can crush the soil with different radius lengths, and the helical blade rotates under the drive of the central rod. Synchronizing the screw blades can lift the crushed soil upwards and discharge it.

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...
