Problems solved by technology
[0003] Therefore, it is necessary to artificially carry out soil regeneration. Before soil regeneration, the contaminated soil will be sampled and tested to determine the cause of soil pollution. In the prior art, only the surface of the contaminated soil is generally sampled. This sampling method cannot fully reflect the soil pollution. The degree of pollution, a kind of sampling equipment that the present invention sets forth is used for polluted soil regeneration, can solve the above-mentioned problem

The invention discloses sampling equipment for contaminated soil regeneration, which comprises a mounting plate, wherein a connecting rod is fixedly connected in the mounting plate; the upper end of the connecting rod is fixedly connected with a case; a driving motor is fixedly arranged in the case; a storage hole is formed in the connecting rod in an up-down penetrating manner; a screw is rotationally arranged in the storage hole; the upper end of the screw is in power connection with the driving motor; and a sliding rod is arranged on the lower side of the screw in a sliding manner. According to the invention, the stress area between the sampling equipment and soil is increased through a supporting plate, so that the fixing effect is improved, shaking in the soil drilling process is avoided, six soil samples with different depths can be collected and detected, and the reason of soil contamination and the depth range of soil contamination can be completely reflected.
Description
technical field [0001] The invention relates to the field of soil regeneration, in particular to a sampling device for regeneration of polluted soil. Background technique [0002] Soil pollutants can be roughly divided into two categories: inorganic pollutants and organic pollutants. Inorganic pollutants mainly include acids, alkalis, and heavy metals. Organic pollutants mainly include organic pesticides, phenols, cyanides, and petroleum. Too many harmful substances, exceeding the self-purification capacity of the soil, will cause changes in the composition, structure and function of the soil, and inhibit microbial activities. [0003] Therefore, it is necessary to artificially carry out soil regeneration. Before soil regeneration, the contaminated soil will be sampled and tested to determine the cause of soil pollution. In the prior art, only the surface of the contaminated soil is generally sampled. This sampling method cannot fully reflect the soil pollution. The degree ...
