Soil heavy metal detecting device

Abstract

The invention relates to the field of soil heavy metal detecting devices, in particular to a soil heavy metal detecting device, which comprises a supporting structure, a pulling structure, a depth adjusting structure, a sample acquisition structure, a guiding structure and a storage structure, wherein the depth adjusting structure is fixed to the supporting structure, is convenient to adjust the depth of an acquired sample, and adopts a lever principle, thereby making the operation more labor-saving and improving the acquisition efficiency; the guiding structure is arranged at the end portionof the depth adjusting structure, the guiding structure encloses a cone structure, has a guiding function for the depth adjusting structure, and effectively prevents the soil at different positions from entering the interior of the sample acquisition structure, thereby making the depth adjustment structure easier to enter the soil, and making soil acquisition effect of the sample acquisition structure better; and the sample acquisition structure is arranged inside the depth adjustment structure, and is convenient to acquire the soil at the same position layer by layer. The arrangement of the sample acquisition structure is convenient for accommodating the acquired sample soil, and is convenient to discharge the collected sample soil.

Description

technical field [0001] The invention relates to the field of soil heavy metal detection devices, in particular to a soil heavy metal detection device. Background technique [0002] Among the soil inorganic pollutants, heavy metals are more prominent, mainly because heavy metals cannot be decomposed by soil microorganisms, but are easy to accumulate and transform into more toxic methyl compounds, and some even accumulate in the human body at harmful concentrations through the food chain, seriously endangering For human health, heavy metal-polluted soil needs to be tested with a soil heavy metal detection device, and then the treatment method should be used reasonably according to the test results. Soil samples need to be taken before soil testing. [0003] However, the method of collecting soil samples in relatively soft geological areas is to first use drilling equipment to drill the soil, and then detect the soil at different depths. The operation is not convenient and quic...

Problems solved by technology

[0003] However, the method of collecting soil samples in relatively soft geological areas is to first use drilling equipment to drill the soil, and then detect the soil at different depths. The operation is not convenient and quick, and during the drilling process, the side of the drill The soil on the wall is easy to collapse, causing soil mixing at different depths, which affects the quality of the measurement. At the same time, the soil needs to be backfilled after drilling holes in the soil, which makes it difficult for operators to collect samples.
