Description

Technical Field

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

[0002] With the development of industry, the amount of wastewater and waste gas generated by industry is increasing, and the pollution to the environment is becoming more and more serious. Among them, soil pollution is a part of environmental pollution. Therefore, scientific researchers need to take samples and analyze the contaminated soil.

[0003] In the prior art, a Chinese patent document with publication number CN218823322U proposes an environmental monitoring soil sampler that achieves the advantages of combining drilling and sampling by combining a vertical rod, a through groove, a horizontal rod, a connecting block, a vertical plate, a threaded sleeve, a threaded rod, a fixed sleeve, a handle, a drill bit and a sampling groove, and solves some defects in the use of previous soil samplers, which do not have the advantages of combining drilling and sampling, increase the difficulty of sampling, and thus reduce the work efficiency of users, and cannot meet the needs of the current market. Due to the above problems, the practicality and usability of the soil sampler are reduced, but consistent with the traditional method, the traditional soil sampler has the problem of soil loss during the extraction process. When the sampler is pulled out of the soil, the surrounding soil tends to fall outward and downward due to gravity. This situation will result in some soil samples not being completely collected inside the sampler, resulting in a reduction in the number of samples taken. This problem is more significant, especially in soft or moist soils, because the fluidity of the soil is enhanced, resulting in more soil loss. This soil loss will not only affect the accuracy of sampling, but may also affect the reliability of subsequent soil analysis and experimental results. Utility Model Content
