Rock-soil sample drilling device for geological exploration

Abstract

The invention discloses a rock-soil sample drilling device for geological exploration, which is characterized in that the device comprises a fixing frame, a driving motor, a rotating module, a lockingmodule and an auger stem; the fixing frame comprises a shell arranged on the upper portion and a bottom plate arranged on the lower portion, and a detachable cover body is arranged at the top of theshell; the rotating module is arranged between the shell and the bottom plate; the locking module is arranged in the shell; the bottom of one end of the shell is fixedly connected with one side of thebottom plate through a first support; the bottom of the other end of the shell is fixedly connected with the other side of the bottom plate through a second support; the driving motor is fixedly arranged on one side below the bottom plate, and an output shaft of the driving motor penetrates through the bottom plate to drive the rotating module to rotate; an inner sleeve for storing a sampled sample is arranged in the auger stem in a sleeved mode, and the inner sleeve and the auger stem are coaxially arranged; and the auger stem sequentially penetrates through the shell, the locking module inthe shell, the rotating module and the bottom plate from top to bottom, and the tail end of the auger stem extends to the position below the bottom plate. The drilling device can quickly enter and exit samples, is simple and convenient to operate, saves manpower and material resources, and effectively improves the working efficiency.

Description

technical field [0001] The invention relates to the technical field of geological exploration equipment, in particular to a rock and soil sample drilling device for geological exploration. Background technique [0002] Geological prospecting is a scientific activity that explores, detects and studies geological soil through various methods. The analysis results of geological prospecting play an important role in agriculture, science, mining and other fields. Soil sampling is often required for geological prospecting. The analysis and study of soil composition can determine the geological properties of the area. The most widely used exploration method in "geological exploration" is drilling, that is, drilling holes in the stratum with a drilling rig to identify and divide the subsurface strata, and can follow the hole An exploration method of deep sampling. Drill pipe is used in drilling. The drill pipe is a steel pipe with threaded tail, which is used to connect the surface ...

[0002] Geological prospecting is a scientific activity that explores, detects and studies geological soil through various methods. The analysis results of geological prospecting play an important role in agriculture, science, mining and other fields. Soil sampling is often required for geological prospecting. The analysis and study of soil composition can determine the geological properties of the area. The most widely used exploration method in "geological exploration" is drilling, that is, drilling holes in the stratum with a drilling rig to identify and divide the subsurface strata, and can follow the hole An exploration method of deep sampling. Drill pipe is used in drilling. The drill pipe is a steel pipe with threaded tail, which is used to connect the surface equipment of the drilling rig and the drilling and grinding equipment or the bottom hole device at the bottom of the drilling well. However, currently The most commonly used soil-borrowing tools have a drill pipe, a drill bit, and a "T" handle. By manually rotating the handle, the soil-boring drill is pressed into the soil in a spiral shape for sampling. After the sampling, the drill is lifted by hand to obtain samples. , time-consuming and labor-intensive, low work efficiency, and most of the soil collection places are designed with openings, which cannot accurately take soil, which affects the sampling accuracy of the soil and ultimately affects the research quality of geological exploration
