Soil sampling device for geological exploration

Abstract

The invention belongs to the technical field of geological exploration, and particularly relates to a soil sampling device for geological exploration which comprises a fixing frame, an air cylinder is mounted in the middle of the upper surface of the fixing frame, a first motor is mounted on a telescopic shaft of the air cylinder, and a drill rod is mounted on an output shaft of the first motor. Fixing plates are symmetrically welded to the left end and the right end of the upper surface of the fixing frame, supporting rods are installed on the bottom faces of the fixing plates, and sliding barrels are slidably connected to the outer side walls of the supporting rods. When the fixing frame is placed at a sampling point, if one side of the fixing frame is in a low-lying position, the inclination state is judged by checking the gradienter, the PLC is in signal connection with the first WIFI module, and the electric push rod is in signal connection with the PLC through the first WIFI module, so that the starting of the electric push rod or the extending length of the telescopic end of the electric push rod can be directly controlled through the PLC to ensure that the upper surface of the fixing frame is horizontal, so that the balance of the device is ensured, and the later sampling operation is facilitated.

Description

technical field [0001] The invention belongs to the technical field of geological prospecting, in particular to a soil sampling device for geological prospecting. Background technique [0002] Geological exploration is the investigation of geological conditions such as rocks, stratum structures, minerals, groundwater, and landforms in a certain area by using geological exploration methods such as surveying and mapping, geophysical exploration, geochemical prospecting, drilling, pit exploration, sampling testing, and geological remote sensing. Research work, soil sampler, refers to the tools used to obtain soil samples. Commonly used are soil drills, shovels and shovels. The soil drills are composed of drill bits and handles made of hard materials. The drill bits are usually spiral or barrel. Shaped, the top of the helical drill is a pair of sharp blades that can be rotated and cut into the soil, followed by an enlarged soil-holding cavity, which drills down into the soil sur...

AI Technical Summary

Problems solved by technology

[0004] 1. When sampling through the soil sampling device, if the ground at the sampling point is not level, it is easy to make the device tilt as a whole when placed, which is not conducive to protection balance and inconvenient to use;

[0005] 2. After the existing soil sampling device drills the sample through the drill pipe, because it does not have the auxiliary sampling function, it is inconvenient to take the sample out of the drill pipe as a whole, which increases the difficulty of sampling;

[0006] 3. In the existing soil sampling device, when the first motor drives the drill pipe to rotate rapidly, because there are no auxiliary stabilizing devices on both sides of the fixed frame, it is easy to cause the device to shake during sampling and affect the progress of sampling
