Description

Technical Field

[0001] The utility model relates to the technical field of soil heavy metal sampling, in particular to a sample collection device for heavy metal analysis. Background Art

[0002] Heavy metals are particularly prominent among inorganic pollutants in soil, mainly because heavy metals cannot be decomposed by soil microorganisms and are easily accumulated and converted into more toxic methyl compounds. Some even accumulate in the human body at harmful concentrations through the food chain, seriously endangering human health. Therefore, how to remediate heavy metal-contaminated soil on a large scale has become one of the important issues facing environmental remediation in my country at present and in the future.

[0003] In the prior art, when remediating heavy metals in soil, it is first necessary to sample and test the soil. However, the existing sample collection device for heavy metal remediation in soil uses a manual digging method, which is inefficient. Therefore, a sample collection device for heavy metal analysis is proposed.

The utility model movably mounts a slider on the base, rotates the threaded column by rotating the handle, drives the slider to move in the strip hole on the base, thereby driving the spiral tube to move, and finds the next suitable soil for collection, and then enables the spiral tube to move left and right, thereby solving the problem of the inconvenience of the collection device encountering obstacles when collecting samples.

[0005] Although the above patent achieves the goal of rotating the threaded column by turning the handle to drive the slider to move the bar hole on the base, thereby driving the spiral tube to move and find the next suitable soil for collection, and then allowing the spiral tube to move left and right, thus solving the problem of the collection device being inconvenient to move when encountering obstacles when collecting samples; however, the device lacks a protective structure. When sampling soil samples, the soil will splash around, which may cause harm to surrounding workers, and the soil may contain heavy metal components, which may pose a potential health risk if in contact with human skin for a long time.

[0006] Therefore, it is necessary to invent a sample collection device for heavy metal analysis to solve the above problems. Utility Model Content
