Description

Technical Field

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

[0002] Soil is the foundation of ecosystems and plays a vital role in agricultural production, environmental protection, and natural resource management. Soil surveys involve collecting and analyzing soil samples to assess their properties, quality, and distribution, providing a scientific basis for land use, agricultural development, and environmental management. The quartering method is a commonly used soil sampling method. Its basic principle is to uniformly mix the soil sample, divide it into four equal parts, and then select a portion from each part as the final sample. This method effectively reduces sample randomness and improves sample representativeness.

[0003] The existing technology has the following shortcomings: The existing technology disclosed in CN202320598752.7 is a soil quartering method sample preparation device, which includes a bottom tray with a central fixed shaft fixedly connected to the upper surface of the bottom tray; an annular inner cylinder, which is rotatably installed outside the central fixed shaft and concentric with it, and a quartering plate fixedly connected to the inner cavity of the annular inner cylinder; and four inner cylinder openings arranged in a ring array on the side of the annular inner cylinder; and an annular outer cylinder, which is rotatably installed outside the annular inner cylinder and fits against the outer wall of the annular inner cylinder, and an outer cylinder opening corresponding to the four inner cylinder openings through the outer wall of the annular outer cylinder.

[0004] While the aforementioned equipment can conveniently perform quartering sampling of soil, it lacks a good soil pulverizing mechanism during operation. When dividing large soil clumps, it is difficult to improve the detection accuracy of the divided samples, which limits the effectiveness of soil survey and testing. Utility Model Content
