The invention relates to the technical field of soil sampling, in particular to contaminated soil investigation sampling equipment which comprises a sampler shell and a sampling tube. The humidity of lower-layer soil is larger than that of upper-layer soil, the resistivity of the lower-layer soil is small, and the resistance value of the lower-layer soil is small, so that current of a storage battery is transmitted to a first electromagnetic block through a conductive wire, a second conductive rod, the lower-layer soil and a first conductive rod, and the magnetic force of the first electromagnetic block is increased, and the first electromagnetic block adsorbs the magnetic sampling groove to move downwards; and when the magnetic sampling groove moves downwards to the bottom end of the sampling pipe, the magnetic sampling groove approaches to enable the magnetic sensitive resistor to control the magnetic pulling force of the second electromagnetic block to be increased and adsorb the magnetic baffle to promote the magnetic sampling groove to be opened, and meanwhile, the opening area of the magnetic baffle can scrape off upper soil on the surface of the soil to be sampled; at the moment, the sampler is controlled to continuously move downwards, so that the lower-layer soil can enter the magnetic sampling groove, and the lower-layer soil is prevented from being polluted by upper-layer soil remained on the inner wall of the sampling pipe when the equipment samples the lower-layer soil.
Description
technical field [0001] The invention relates to the technical field of soil sampling, in particular to a polluted soil survey sampling device. Background technique [0002] Soil sampling equipment is a scientific instrument used in the fields of geological science, environmental science and technology, and resource science and technology. It mainly samples the underground soil to detect the underground soil composition, so as to judge the pollution degree of the soil or the environment. To facilitate the implementation of soil environmental protection measures. [0003] Chinese patent CN111175073B discloses a special soil sampling device for soil pollution improvement, which includes a sampler housing, and a sampling space with an opening facing downward is provided in the sampler housing, and a sampling mechanism is provided in the sampling space, and the sampling mechanism includes Rotate the gear shaft arranged on the rear end wall of the sampling space, a gear is fixed ...
