Problems solved by technology
[0006] In order to solve the above-mentioned problems, the present invention provides a soil heavy metal detection process, which can solve the problems that cannot be clamped for different types of crucibles, need to manually shake the crucible, etc. When the crucible shakes, it is easy to cause the mixture in the crucible to spill, and it is easy to cause safety hazards when the crucible is stirred manually. It can be realized that the crucible containing the soil can be clamped and shaken when the soil is acid-treated, and the The function of stirring has the advantages of clamping action for different types of crucibles, mechanized shaking of the crucible, the mixture in the crucible will not be spilled when the crucible is shaken, and there is no safety hazard in the mechanized stirring action of the crucible.

Embodiment Construction
[0034] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0035] Such as Figure 1 to Figure 5 Shown, a kind of soil heavy metal detection technique comprises the following steps:
[0036] Step 1: Soil collection: First, clean up the weeds above the soil layer at any time, then press a plastic sampler with a length of 10 cm and a diameter of 8 cm directly into the soil layer, and then dig out the sampler with bamboo or wood chips, Soil samples are collected separately at multiple locations within a field;
[0037] Step 2: Air-dry the soil samples: Put the collected soil samples in a wooden tray or on a plastic cloth, spread them into a thin layer about 2 cm thick, place them indoors, and turn them over with wooden sticks or glass sticks at intervals to make them airy and dry in the shade , when the soil ...

The invention relates to a soil heavy metal detecting process. The soil heavy metal detecting process comprises the following steps of, firstly, collecting soil; secondly, air-drying a soil sample; thirdly, sieving the soil sample; fourthly, processing the soil sample, specifically, weighing out and placing 500 milligrams of the soil sample into a crucible, and controlling a clamping device mounted on a support base to clamp the crucible, wherein the clamping device comprises a support rack, a stopping mechanism, a clamping pushrod, a lifting plate, a shaking mechanism, a clamping mechanism, aclamping air cylinder, a clamping extending rod and a clamping top plate; fifthly, performing acid treatment on the soil sample; sixthly, performing metal detection; seventhly, performing detection recording. The soil heavy metal detecting process can solve the problems that, during soil acid treatment in existing soil heavy metal detection, clamping different types of crucibles cannot be achieved, manually shaking the crucibles is required, shaking the crucibles is prone to resulting in scattering of mixtures inside the crucibles, manually mixing the crucibles are prone to causing potentialrisks and the like.
Description
technical field [0001] The invention relates to the technical field of agricultural detection instruments, in particular to a soil heavy metal detection process. 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 human health. Heavy metal elements in polluted soil mainly include mercury, cadmium, lead, copper, chromium, nickel, zinc and so on. [0003] Today's soil heavy metal detection equipment is not very accurate in the detection of heavy metals, especially the soil deep in the field cannot be detected by detection equipment, and the deep soil can only be detected by chemical detection methods. [0004] Existing patents also propose a detection method for heavy m...
