Description

Technical Field

[0001] The utility model relates to the technical field of ecological environment, in particular to a soil detection sampler. Background Art

[0002] Soil environmental monitoring refers to an important measure to understand the status of soil environmental quality. It is aimed at preventing and controlling the hazards of soil pollution and involves dynamic analysis and measurement of the degree and development trends of soil pollution. It includes surveys of the current status of soil environmental quality, surveys of regional soil environmental background values, investigations of soil pollution accidents, and dynamic observations of contaminated soil. Soil environmental monitoring generally includes steps such as preparation, site placement, sampling, and sample preparation.

[0003] Patent publication number CN220170558U discloses a sampler for soil testing, including a handle structure and a sampling structure. The handle structure is connected to the sampling structure through a threaded connection. A hollow cylindrical support frame lower rod is provided on the sampling structure. A sampling head is welded to the lower end of the support frame lower rod. A limiting plate is fixed to the inner wall of the upper end of the support frame lower rod. A sampling cavity is provided in the sampling head. A fixed plate is provided at the center position of the upper part of the sampling head. The fixed plate is located inside the support frame lower rod. A bulldozer structure that can move up and down is provided inside the support frame lower rod.

[0004] In order to solve the problem that the existing soil sampler is difficult to remove soil with high viscosity, the existing technology is to place the protrusion of the bulldozer base on the horizontal step at the upper part of the horizontal limit groove and fix it, then hold the anti-slip sleeve with both hands to make the sampling head penetrate into the soil. After taking the soil, the protrusion part of the bulldozer base is rotated and placed in the other direction of the upper part of the horizontal limit groove, and then the protrusion part of the bulldozer base is pushed to completely remove the soil. However, there may still be a situation where the soil layer is hard, which makes it difficult for the sampler to take samples. Utility Model Content

If the sampling depth cannot be reached by using a single screw rod 36 during the sampling process, another screw rod 36 is taken out of the storage box 29, and the two screw rods 36 are connected to increase the sampling depth. After the sampling is completed, the push plate 373 is pressed downward. The push plate 373 drives the circular plate 371 to slide downward in the sampling head 37 through the connecting column 372, and the circular plate 371 pushes the sample soil in the sampling head 37 out of the sampling head 37.
