Description

Technical Field

[0001] This utility model belongs to the field of soil remediation technology, and in particular relates to a sampling device for soil improvement and remediation. Background Technology

[0002] Currently, soil sampling devices are crucial tools for obtaining soil samples, assessing soil pollution, and developing remediation measures, and their importance is self-evident.

[0003] A search revealed Chinese patent application number 202323426024.7, which discloses a sampling device for soil improvement and remediation. The device includes a horizontal handle with a sampling cylinder fixedly connected to the bottom center. A push rod is installed inside the sampling cylinder, and a push block is connected to the bottom of the push rod. The push rod and push block facilitate the removal of soil from the sampling cylinder after sampling. A cleaning layer helps to remove residual soil from the inner wall of the sampling cylinder, preventing it from affecting subsequent soil sampling results. A pivot is installed between the upper and lower rods. If the upper rod is pushed out completely as the sampling cylinder is inserted deeper, potentially touching the sampler's face, the pivot allows the sampler to simply push the upper rod forward to rotate it to one side, then press the horizontal handle downwards to continue sampling the soil.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: non-professionals cannot effectively perform layered extraction of soil samples, and soil samples are inconvenient to extract using a sampler when they need to be mailed or stored. Summary of the Invention

[0005] To address the issue that soil samples taken by non-professionals need to be mailed or preserved intact when collected by a sampler, this invention provides a sampling device for soil improvement and remediation.

A placement groove is provided on the side plate, which works in conjunction with the cover plate. This forms a structure where, when the side plate is in the groove, the cover plate rotates 90 degrees to the placement groove, and when the side plate moves out of the groove, the cover plate blocks the groove under the action of the torsion spring.

[0011] In summary, this application includes the following beneficial technical effects: 1. It sets up a sampling tube that can be opened or closed, and sets up an inner tube for placing soil samples inside the sampling tube. It sets up a prying mechanism inside the sampling tube for separating the tube body and the inner tube, and achieves bagging of soil samples with the cooperation of a packaging mechanism at one end of the sampling tube body, ensuring the integrity of the soil samples and facilitating subsequent testing work.
