Geological prospecting instrument convenient to adjust

Abstract

The invention discloses a geological prospecting instrument convenient to adjust, wherein the instrument comprises a box body, a connecting rod and a sampling device; the box body is internally provided with a servo motor; the connecting rod is perpendicular to the bottom surface of the box body; one end of the connecting rod penetrates the bottom face of the box body and is fixedly connected withthe output end of the servo motor, and the other end of the connecting rod is rotationally connected with a circular disc; the sampling device comprises a transmission mechanism, a fixed block and asampling block; the fixed block and the sampling block are in transmission connection through a lead screw of the transmission mechanism, and the fixed block is arranged above the sampling block; theconnecting rod penetrates through the top surface of the fixed block and extends into the fixed block; and the circular disc is arranged in the fixed block and is matched with the top surface of the sampling block. According to the invention, the integrity of a soil sample can be realized, and effective scraping of the soil sample on the inner wall of a tank during sampling is ensured.

Description

technical field [0001] The invention relates to the technical field of geological prospecting, in particular to a geological prospecting instrument which is easy to adjust. Background technique [0002] Geology generally refers to the nature and characteristics of the earth, mainly referring to the material composition, structure, structure, development history, etc. The output state, contact relationship, the history of the earth's structural development, biological evolution and climate change, as well as the occurrence and distribution of mineral resources, etc. Geological exploration refers to the exploration and detection of geology through various means and methods , determine the appropriate bearing layer, according to the foundation bearing capacity of the bearing layer, determine the foundation type, calculate the investigation and research activities of the foundation parameters, there are still some problems in the existing soil sampling device for geological expl...

Problems solved by technology

[0002]Geology generally refers to the nature and characteristics of the earth, mainly referring to the material composition, structure, structure, development history, etc. of the earth, including the differentiation of the earth's circles and physical properties , chemical properties, rock properties, mineral composition, rock stratum and rock mass output state, contact relationship, the earth's structural development history, biological evolution history and climate change history, as well as the occurrence and distribution of mineral resources, etc., geological exploration , that is, through various means and methods to conduct geological exploration and detection, determine the appropriate bearing layer, determine the foundation type and calculate the foundation parameters according to the foundation bearing capacity of the bearing layer. There are also certain problems in the soil sampling device for exploration. For example, the patent No. is CN210217653U, a conveniently adjustable soil sampling device for geological exploration. After the device has taken the soil, it cannot conveniently take out the soil located in the soil extraction head completely, and the soil located on the inner wall of the soil extraction head cannot be scraped clean during sampling, which will easily affect the subsequent sampling. In view of Therefore, we propose a geological prospecting instrument that is easy to adjust
