Description

Technical Field

[0001] This utility model relates to the technical field of soil sampling, and in particular to a sample storage structure for soil. Background Technology

[0002] Soil sampling refers to the process of obtaining representative samples from the soil. This process is commonly used in fields such as agriculture, environmental science, and geology to analyze the physical, chemical, or biological properties of the soil. Soil sampling is one of the fundamental tasks for soil research and management. Through sampling, researchers and agricultural workers can understand the suitability of the soil, such as soil fertility, pollution levels, and soil type, thereby providing a scientific basis for the rational use of soil resources and environmental protection.

[0003] When testing soil fertility, the conventional method involves inserting a soil fertility analyzer into the soil to obtain preliminary data. If the data meets expectations, the analyzer moves to another plot for retesting. If the data does not meet expectations after changing plots, soil samples from that area need to be taken for laboratory testing. Currently, when sampling soft soil, the soil tends to adhere to the inner wall of the sampling bottle. Upon removal, some soil may remain inside the bottle, reducing the sample size. Furthermore, this residual soil may have specific properties; for example, soil near the bottle wall may have undergone physical or chemical changes due to contact, and its loss can render the sample unrepresentative. For instance, when studying soil microbial distribution, the microbial community in the portion of soil adhering to the bottle wall may differ from other parts, and the reduction in sample size and the loss of this soil portion can affect the research results.

[0004] Currently, no effective solution has been proposed to address the issues of loose soil residue remaining inside the bottle and reduced sample volume in related technologies. Utility Model Content

[0163] The method of using this utility model is as follows:

[0164] (a) Storage operations

[0165] Twist the second sealing element 403 to rotate it around the circumference of the sampling element 401 until it is disengaged from the sampling element 401;

[0166] The sampled soil is placed in the sampling element 401;

[0167] Connect the second sealing element 403 to the sampling element 401 by thread until the second sealing element 403 is tightened.

[0168] (II) Placement Operation

[0169] The sampling element 401 containing soil is placed in the placement element 102;

[0170] Connect the first sealing element 104 to the main body element 101 by thread until the first sealing element 104 is tightened.

[0171] During the process, as the first sealing element 104 is twisted, the limiting element 105 comes into contact with the second sealing element 403;

[0172] The first sealing element 104 squeezes the sampling element 401. The sampling element 401 drives the movable element 201 to move downward along the axial direction of the second sliding element 301 through the ejector element 202, thereby squeezing the elastic element 302 to produce deformation.

[0173] (III) Remove sampling element 401

[0174] Twist the first sealing element 104 to rotate it around the circumference of the main body element 101 until it disengages from the main body element 101;

[0175] During the process, as the first sealing element 104 gradually loosens, the sampling element 401 is pushed out by the ejector element 202 under the action of the elastic element 301, so that the sampling element 401 gradually moves upward along the axial direction of the placement element 102, thereby removing the sampling element 401.

[0176] (III) Soil Removal

[0177] Twist the control element 503 so that it drives the second rotating element 502 to rotate along the circumference of the first rotating element 402 while moving upward along the axial direction of the first rotating element 402.

[0178] The second rotating element 502 drives the scraping element 501 to move along the axial direction of the sampling element 401, thereby scraping out the soil.

[0179] The advantages of this invention are that the soil inside the sampling unit can be directly scraped out by the cooperation between the sampling unit and the scraping unit, which replaces the tools for digging out the soil, avoids soil residue inside the sampling unit, improves the convenience of soil removal, and ensures the soil research results; the sampling unit can be pushed up by the cooperation between the ejection unit and the elastic unit, making it easier to remove the sampling unit from the main unit, which improves the convenience of the overall structure.
