Problems solved by technology

And the existing soil sampling device, when carrying out soil sampling, among the soil samples that it takes, there are many useless soil samples, the resistance that the sampling device penetrates into the soil is relatively large, and when the sample is taken out, the attached soil and sampling will produce There is a lot of soil, it is easy to cause the unmined soil to collapse, and it is not easy to sample at multiple fixed points in a large area

Abstract

The invention discloses a sampling device for repairing heavy metal contaminated soil by biochar, which comprises: a frame fixed at a fixed point to be sampled, one side of which is provided with an intelligent screen for monitoring and regulation; two groups of lifting frames which are longitudinally mounted on the left side plate and the right side plate of the building frame; two sets of placing plate frames which are transversely installed on the lifting frame on the left side and the lifting frame on the right side and are arranged in an upper-line parallel mode, longitudinal splicing rods are placed on the upper placing plate frame, and first longitudinal couplings are placed on the lower placing plate frame and used for splicing of the splicing rods; driving clamping seats which are arranged into two groups, are respectively mounted on the corresponding placing plate frames, and are used for taking and placing the corresponding splicing rods and the couplings I; and a sampling device which is mounted at the lower end of the first group of coupling I.

Description

technical field [0001] The invention relates to the technical field of soil sampling and detection, in particular to a sampling device for remediating heavy metal polluted soil with biochar. Background technique [0002] Soil heavy metal pollutants mainly include heavy metal elements such as mercury, cadmium, lead, and chromium. After being absorbed by plants, they remain in plants. Not only can plants grow and develop, but they can also indirectly cause damage to human health. Among them, anions exist in the soil Mercury can be absorbed by clay minerals, and mercury in the form of cations can also be adsorbed by negatively charged clay mineral bands, so soil sampling is required. And the existing soil sampling device, when carrying out soil sampling, among the soil samples that it takes, there are many useless soil samples, the resistance that the sampling device penetrates into the soil is relatively large, and when the sample is taken out, the attached soil and sampling w...
