Embodiment 2
[0047] Such as Figure 1-12 As mentioned above, the difference with Embodiment 1 is that the transmission cylinder 22 is disassembled and installed with the extension cylinder 6 through the first connection groove 61, and the lower end of the extension cylinder 6 is provided with a connection cylinder 62 matching the first connection groove 61, so The connecting cylinder 62 is threadedly connected to the first connecting cylinder 61 , and the upper end of the extension cylinder 6 is also provided with a first connecting groove 61 .
[0048] When it is necessary to sample the soil in the deeper soil layer, the extension tube 6 is loaded into the first connection groove 61 on the soil drill 2 through the connection tube 62, and the extension tube 6 is packed into the inner pipe 4, and the extension tube 6 is connected with the inner tube 6. There is a gap fit between the pipes 4, and the cover is installed on the top of the extension tube 6, and then the steps in the embodiment ...

The invention, which belongs to the technical field of soil sampling devices, mainly relates to an undisturbed soil sampling device comprising a positioning plate and a soil sampling drill. An inner tube is installed in the soil sampling drill. A first via hole is formed in the positioning plate. The soil sampling drill includes a soil-crushing cylinder and a transmission cylinder; a soil-crushingthread is formed in the soil-crushing cylinder; the transmission cylinder is provided with a transmission thread; and the transmission thread and the soil-crushing thread have opposite directions. Afirst chute is formed in the outside of the transmission cylinder axially; a transmission ring sleeves the transmission cylinder in a sliding manner; the inner diameter of the transmission ring is larger than the outer diameter of the transmission cylinder; a sliding block matching the first chute is formed on the inner wall of the transmission ring in an integrated manner; and a stress application rod is installed on the transmission ring detachably. A drill-up nut matching the transmission cylinder is arranged at the upper part of the positioning plate. Therefore, problems that the undisturbed soil can not be obtained easily by the traditional soil sampling drill and the long soil sampling drill can not be used conveniently because forces need to be applied to the top of the soil sampling drill in use are solved.
Description
technical field [0001] The invention belongs to the technical field of soil sampling devices, in particular to an undisturbed soil sampling device. Background technique [0002] Soil sampling is an important method for ecological environment investigation, environmental monitoring, and pollution prevention and control. However, in the current sampling process, there are problems of disturbance and pollution of different soil layers, so that the collected samples cannot truly reflect the original state of the soil; in addition, in some deep soil layers In areas where soil science research is carried out, it is necessary to accurately obtain soil samples at different levels in order to better speculate on erosion deposition and water migration information. [0003] At present, when soil sampling is carried out, soil augers are often used for sampling. The soil auger is drilled into the soil layer through a spiral method, and then reversely rotated to pull it out. However, the ...
