Description

Technical Field

[0001] The present invention belongs to the technical field of geotechnical sampling equipment, and particularly relates to a geotechnical layer sampling equipment for geological detection. Background Art

[0002] Soil sampling refers to the method of collecting soil samples, including the layout of sampling and sampling techniques. For sampling profile soil samples, it should be carried out after the profile observation and record are completed. Before sampling, the profile should be renovated, cleaned, and the top layer of floating soil should be shaved off. Then, samples should be taken layer by layer from the central typical part from top to bottom. Corresponding sampling equipment will be used when sampling geotechnical materials; Traditional sampling equipment includes structures such as a guiding groove, positioning nails, a central rod, a hammering part, guiding protrusions, a transmission rod, an adjusting ring, a transmission ring, a transmission block, a cutting ring, and a spacer ring. The advantage of this sampling equipment is that sampling can be carried out through the lateral movement of the cutting ring; However, when the traditional sampling equipment is used, sampling is only carried out through the simple lateral movement of the cutting ring. When the cutting ring resets, the cutting ring is very easy to separate from the soil, resulting in the sampling equipment being unable to effectively sample, and the sampling reliability of the sampling equipment is poor and needs to be improved urgently.

[0026] The working principle and usage process of the present invention: Before use, corresponding pits are dug in the rock and soil with tools such as shovels, and then the sampling device is placed in the pits. Then the user presses down the adjustable drive plate 212. At this time, the pressure regulating piston plate 210 moves downward to press the flowable transmission liquid 31, so that a plurality of deformable samplers 32 are synchronously extended under the hydraulic action. At this time, the sampling metal tube 325 passes through the anti-tipping metal seat 1 and inserts into the soil. Then the user presses the second limit drive plate 223. At this time, the limit drive gear plate 221 moves downward to cooperate with the drive gear column 328 to drive the sampling metal tube 325 to rotate. At this time, the rock and soil are cut by the limit cutting member 326 at the end of the sampling metal tube 325, so that the sampled rock and soil can be reliably retained inside the sampling metal tube 325. Then the second limit drive plate 223 is pulled up to reset the limit drive gear plate 221 above the sampling metal tube 325; Then, release the pressing on the adjustable drive plate 212. At this time, the sampling device returns to its initial form, and the user can directly take out the sampling device from the pit. That is to say, the user can achieve synchronous sampling of multiple deformable samplers 32 at different heights and different positions with only two simple presses, significantly improving the sampling speed and sampling effect of the sampling device. And through cutting, the sampled rock and soil can be reliably retained inside the sampling metal tube 325, improving the sampling reliability. The threaded connection of the transmission gear column 328 facilitates the user to remove the sampling metal tube 325. At this time, the user can push the movable ejector plug 327 inside the sampling metal tube 325 by passing a rod-shaped object such as a metal rod through the transmission gear column 328. Then, the sampled rock and soil can be completely detached by the movement of the movable ejector plug 327, and the inner wall of the sampling metal tube 325 can be fully cleaned, facilitating the user to use the sampling device subsequently; Thus, through the mutual cooperation of multiple structures, the sampled rock and soil are cut, avoiding the phenomenon that the device cannot effectively sample, and improving the sampling reliability of the device. Secondly, the present invention can synchronously sample multiple layers of rock and soil, significantly improving the sampling efficiency of the sampling device. In addition, the present invention is easy to maintain, and has a simple structure and is convenient to use, improving the user experience of the sampling device.
