Embodiment 1

[0033] Such as Figure 1 to Figure 3As shown, the present embodiment provides a soil fetcher for geological detection, comprising a drill pipe 1, the top of the drill pipe 1 is provided with a handle 2, the bottom of the drill pipe 1 is fixedly connected with a sampling cylinder 3, and the bottom of the sampling cylinder 3 is fixedly connected with a Drill bit 4, wherein, there are four sampling scrapers 5 with four openings facing the side wall of the sampling barrel 3 and the back facing the center of the sampling barrel 3 in the sampling cylinder 3 at equal central angles. The space inside can store four groups of samples at the same time. The opening surface of the sampling scraper 5 is arc-shaped to ensure a wider range of contact with the target soil layer, and sampling is simpler and faster; The shaft center of the cylinder 3 is radially slidably connected to the center of the circle. Preferably, the bottom surface of the sampling cylinder 3 is provided with a radially ...

Embodiment 2

[0036] Such as figure 1 and figure 2 As shown, the present embodiment is further optimized on the basis of embodiment 1, specifically:

[0037] The closing mechanism includes a limiting cylinder 11 that is rotatably set in the sampling cylinder 3 and fits with the inner wall of the sampling cylinder 3 and penetrates through the lower end. The limiting cylinder 11 is rotatably connected with the sampling cylinder 3. The top of the limiting cylinder 11 is provided with a second rotating For the driving mechanism, four limiting openings 12 corresponding to the four outlets 6 are opened on the side wall of the limiting cylinder 11 . Rotate the limiting cylinder 11 by the second rotating drive mechanism, so that the limiting port 12 and the outlet 6 are aligned or staggered one by one, the closing and opening of the outlet 6 of the sampling cylinder 3 can be realized, the structure is simple and easy to operate, and the practicability is strong;

Embodiment 3

[0039] Such as figure 1 and figure 2 As shown, the present embodiment is further optimized on the basis of embodiment 1 and embodiment 2, specifically:

[0040] The drill rod 1 is a hollow drill rod 1 that communicates with the sampling cylinder 3, wherein the second rotation drive mechanism includes a hollow stop rod 13 that communicates with the stop tube 11 and is fixedly connected with the stop tube 11. The stop rod 13 passes through Located in the inner cavity of the drill pipe 1, the top end of the stopper rod 13 protrudes from the handle 2 at the top of the drill pipe 1 and is provided with a switch handle 14; the first rotary drive mechanism includes a rotary handle 15, and the top end of the drive shaft 7 passes through the stopper rod The inner chamber of 13 stretches out switch handle 14 and is fixedly connected with rotary handle 15. By rotating the handle 2 on the top of the drill rod 1, the switch handle 14 and the rotating handle 15, the drill rod 1 can be lo...

Abstract

The invention discloses a soil sampler used for geological detection and belongs to the technical field of geological detection. The soil sampler comprises a drill rod; the bottom of the drill rod isconnected with a sampling cylinder; the bottom of the sampling cylinder is connected with a drill head; a plurality of sampling scrapers are distributed at intervals of equal central angles in the sampling cylinder; a plurality of outlets which are in one-to-one correspondence with the opening surfaces of the sampling scrapers are formed in the cylindrical wall of the sampling cylinder; the outlets are provided with opening-closing mechanisms which can open and close the outlets; a sampling driving mechanism which is used for pushing the sampling scrapers out of the outlets or retracting the sampling scrapers is arranged in the sampling cylinder; the sampling driving mechanism includes a driving shaft; the driving shaft is provided with protruding driving blocks; the number of the protruding driving blocks is equal to the number of the sampling scrapers; the driving shaft servers as the rotation axis of the protruding driving blocks; each protruding driving block is tangent to the backof the scraper corresponding to the protruding driving block; and a reset spring is connected between the back of each sampling scrapper and the driving shaft. According to the soil sampler of the invention, the sampling scrapers can be flexibly pushed out or retracted, and therefore, soil from other soil layers can be prevented from entering the sampling cylinder, and the purity of a sample canbe effectively ensured.

Description

technical field [0001] The invention relates to the technical field of geological detection and is used for extracting soil samples in geological detection, in particular to a soil fetcher for geological detection. Background technique [0002] Geological exploration is based on the needs of economic construction, national defense construction and scientific and technological development, using surveying and mapping, geophysical prospecting, geochemical prospecting, drilling, pit exploration, sampling testing, geological remote sensing and other geological prospecting methods to investigate the rocks and strata in a certain area. Investigation and research work on geological conditions such as structures, minerals, groundwater, and landforms. [0003] In geological prospecting and reconnaissance, in order to obtain the physical and mechanical properties of foundation soil, in addition to in-situ testing, indoor geotechnical experiments are mainly used after drilling and samp...
