Description

Technical Field

[0001] The utility model belongs to the technical field of soil sample sampling in the process of environmental detection, and more specifically, particularly relates to a multi-point sampling device. Background Art

[0002] During the environmental testing process, since some pollutants will penetrate into the interior of the soil, when testing the environment, in addition to sampling and testing the air in the current environment, a corresponding sampling device is also required to sample the soil in the location that needs to be tested, and subsequent testing and other work are performed to detect the soil condition at the current location. However, when the existing sampling device is sampling, it is mostly a single-tube sampling structure. When multi-point sampling operations are required, multiple sampling tubes need to be taken out manually at the same time in sequence to achieve multiple multi-point sampling operations. Therefore, the sampling tube needs to be repeatedly taken out and used each time when sampling is performed, which will result in low sampling efficiency. Utility Model Content
