Description

Technical Field

[0001] The utility model relates to the field of detection devices, in particular to a soil pollution investigation and detection device. Background Art

[0002] When conducting on-site heavy metal detection on soil, it is necessary to first sample the soil and then test the excavated soil. Usually, a soil heavy metal analyzer is used for spectral analysis to determine whether it is polluted or the degree of pollution. The soil sampling device in the prior art can obtain soil of different depths when sampling. The specific operation is: when inserting the sampling tube into the soil, the opening of the sampler is facing the side and facing the soil, and then the soil of different depths is collected by the sampler. After the sampling is completed, the sampling tube is pulled out of the soil to obtain a sample.

[0003] After searching, the Chinese patent publication number CN219935350U discloses a soil sampling device, which can simultaneously sample soil at different depths through multiple groups of storage boxes set on the sampling tube, effectively improve the efficiency of soil sampling, reduce the workload during sampling, and place samples of different depths separately through the storage boxes, and seal and isolate the soil samples in the storage boxes through a scraper.

[0004] In the above patent, due to the loose soil structure, the scraped soil sample cannot smoothly pass through the guide slot into the storage box, which is not conducive to taking out the soil sample. Since the sampling tube is long, it is easy to tilt during the insertion into the soil, making the sampling depth inconsistent with the actual depth and reducing the accuracy. Utility Model Content
