Embodiment
[0038] Please refer to figure 1 , a hydrogeological drilling detection device, including: a support frame (not shown), a stabilizer 10, a drilling assembly 20 and a power assembly 30. The drilling assembly 20 is installed on the stabilizer 10, and the drilling assembly 20 is connected with the power assembly 30, and driven by the power assembly 30, the drilling assembly 20 can be extended into the ground for soil sample collection. The power assembly 30 is installed on the support frame.
[0039] Please refer to figure 2 with image 3 , the stabilizer 10 includes a connecting cylinder 11 , a plurality of first braces 12 and a plurality of second braces 13 . The connecting cylinder 11 is arranged vertically, and the inner side wall of the connecting cylinder 11 is provided with an internal thread. All the first diagonal braces 12 are in an inclined state, and all the first diagonal braces 12 are evenly spaced around the connecting cylinder 11, that is, all the first diagon...

The invention discloses a hydrogeological drilling type detection device, which belongs to the technical field of hydrogeological detection. A hydrogeological drilling type detection device, comprising: a supporting frame, a stabilizing frame, a drilling assembly arranged on the stabilizing frame, and a power assembly arranged on the supporting frame; the drilling assembly includes a vertically arranged drill tube and a drill pipe; The top of the barrel is connected with the power assembly, the outer wall of the drill barrel is connected with the stabilizer through threads, and the bottom end of the drill barrel is provided with a first tapered surface; the drill pipe passes through the drill barrel, and the top of the drill pipe is connected with the power assembly, and the drill pipe The side wall of the drill pipe is connected with the inner side wall of the drill pipe through threads, and a drill bit is provided at the bottom of the drill pipe, and the second cone surface of the drill bit is located in the extending direction of the first cone surface. In the invention, sampling is carried out through the screw groove, and soil at other depths does not enter into the screw groove of the drill pipe during sampling, which avoids soil at other depths from entering the sample, thereby avoiding detection errors caused by the mixing of other soils.
Description
technical field [0001] The invention relates to the technical field of hydrogeological detection, in particular to a hydrogeological drilling type detection device. Background technique [0002] Hydrogeology refers to the various changes and movement phenomena of groundwater in nature, such as the distribution and formation of groundwater, the physical properties and chemical composition of groundwater, so as to make rational use of groundwater. The detection of hydrogeology is helpful for researchers to understand the geological situation. At present, when researchers conduct hydrogeological detection, they generally take out soil samples at a certain depth from the ground by manual drilling for hydrological and hydrogeological detection. However, when drilling, The samples will be mixed with soil at different depths, resulting in errors in the final detection results. At the same time, the drill pipe is prone to jamming during drilling, making it difficult to pull out the ...
