Description

Technical Field

[0001] The utility model relates to the field of soil detection sampling, in particular to a layered sampling device for soil detection sampling. Background Art

[0002] Driven by the Soil Pollution Prevention and Control Law, soil environmental surveys are being carried out in full swing in various places, especially soil environmental monitoring surveys of industrial production sites. Due to the heterogeneity of soil, the collection of soil samples has become the most critical step in soil monitoring. Accurately collecting soil samples that meet regulatory requirements can provide quality assurance for various subsequent test data. Therefore, a stratified sampling device for soil testing and sampling is needed.

[0003] The existing patent document with the technical publication number CN219511845U provides a soil detection sampling device, which specifically relates to the field of soil detection technology, including a circular sleeve, through which a soil breaking device is provided, the vertebral body 2 and the circular sleeve are in a vertical state, such as Figure 1 As shown, it is convenient to break the soil and take samples easily. After taking the soil, the threaded rod can be rotated to move the threaded rod out of the L-shaped plate. The L-shaped plate moves downward under the influence of gravity and no longer supports the vertebral body 2. At this time, the end of the vertebral body 2 rotates downward and is not vertical to the circular sleeve to avoid accidental injury to the staff. When the circular sleeve enters the appropriate position, the threaded column is rotated, which immediately drives the long plate to move upward, and then drives the connecting rods on both sides to move upward, thereby causing the end of the connecting rod away from the long plate to rotate downward, thereby driving the end of the L-shaped rod on both sides away from the T-block to rotate downward, thereby driving the hemispheres on both sides to approach each other, thereby clamping the soil and sampling the soil without repeated sampling. However, the CN219511845U technology is not convenient for folding and storing the device during operation, it is not convenient to prevent the device from moving during sampling, and it is not convenient to observe the sampled soil layer. Therefore, a layered sampling device for soil detection sampling is urgently needed. Utility Model Content
