Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, specifically a soil sampling device for soil analysis. Background Technology

[0002] Soil analysis aims to determine the physical, chemical, and mechanical properties of soil, providing a basis for engineering construction, agricultural production, and environmental protection. Soil sampling is conducted to obtain representative soil samples for various analytical tests in the laboratory. Soil sampling avoids the limitations of field testing, enabling more accurate analysis of soil particle composition, moisture content, density, compressibility, shear strength, and other indicators. This provides reliable data support for soil analysis and helps in the accurate assessment of soil characteristics and engineering performance.

[0003] A soil sampling device for soil analysis, disclosed in patent publication number CN217084251U, includes a push rod and a stop block. Rotating the push rod causes the stop block to move downwards to the bottom of the sampling tube. After selecting the location for soil sampling, the lower opening of the sampling tube is facing downwards, and the sampling device is tapped into the soil. The lower opening of the sampling tube is blocked by the stop block, preventing soil from entering the sampling tube during the tapping process. Once the sampling device has reached the designated depth in the soil, rotating the push rod causes the stop block to move to the upper part of the sampling tube, and then the sampling device is tapped into the soil again to force the soil sample into the sampling tube. Finally, the sampling device is removed from the soil.

[0004] During soil sampling, the aforementioned device requires workers to use their arms to insert the sampling tube and the stop block into the soil simultaneously. Overcoming soil resistance often requires a significant amount of physical exertion. Furthermore, the actual sampling process typically involves repeated operations and prolonged downward insertion, which can easily lead to worker fatigue. In addition, to obtain soil samples at different depths for comprehensive analysis, multiple layers of samples are often required, but the tube length cannot be flexibly adjusted. This not only increases the difficulty of sampling but also affects the efficiency and accuracy of the sampling work. To address these issues, a soil sampling device for soil analysis is proposed.

[0027] The top of the fixed tube 11 is connected to the handle 12 via a snap-fit ​​assembly, and the bottom of a set of fixed tubes 11 at the bottom is threadedly connected to the sampling tube 13.

[0028] The connecting assembly includes several sets of first positioning holes 14 and second positioning holes 17. The first positioning holes 14 are located on one side of the top of the fixing tube 11, and the second positioning holes 17 are located on one side of the bottom of the fixing tube 11. One set of fixing tubes 11 is threaded to another set of fixing tubes 11. A set of positioning bolts 15 are threaded into the first positioning holes 14 and the second positioning holes 17. A slot 16 is provided on one side of the positioning bolt 15.
