The invention relates to a sampling device for soil pollution detection. The sampling device comprises a grip, an outer cylinder, a sampling cylinder and a push rod, wherein one end of the outer cylinder is rotatably connected with a stopper, the other end of the outer cylinder is fixedly connected with the grip, the sampling cylinder is sleeved with the outer cylinder, the push rod is fixedly connected with the sampling cylinder, a plurality of the stoppers are provided, one end of each stopper is rotatably connected with the outer cylinder, the other end of each stopper is provided with a drill bit, and the drill bits are arranged to be in contact with the stoppers. The sampling device divides the sampling operation into a downward pressing process and the sampling process through arranging the stoppers and the drill bits, thus avoids the mixing of upper layer soil and soil with depth to be detected, and has the beneficial effects of high precision, high working efficiency, convenient operation and the like.
Description
technical field [0001] The invention relates to the field of environmental detection, in particular to a sampling device for soil pollution detection. Background technique [0002] Soil remediation is a technical measure to restore contaminated soil to normal functions. Since the 1980s, many countries in the world, especially developed countries, have formulated and carried out plans for the treatment and restoration of polluted soil, thus forming an emerging In the soil remediation industry, in the process of soil remediation, the soil to be remediated needs to be sampled and tested first. At present, when sampling suddenly, most of them use ordinary manual samplers for sampling. The existing manual samplers will The surface soil and the soil at the depth to be tested are taken out as a whole. This method is prone to the upper layer of soil being mixed into the soil at the depth to be tested, resulting in detection errors. At the same time, when the depth of the soil to be ...
