Description

Technical Field

[0001] The utility model belongs to the technical field of soil collection, and in particular relates to a portable soil collection device. Background Art

[0002] The soil collection device, that is, the soil sampler, is a tool specially used to collect soil samples. It is of great significance to soil research, environmental monitoring, water resource protection, etc. Power (gasoline) soil sampler: powered by a gasoline engine, saving manpower, the sampling depth can reach 2 meters, soil nail: used for surface soil sampling, the sampling depth generally does not exceed 30 cm, with a simple structure and convenient sampling.

[0003] During the soil collection process, the devices used often face the challenge of size mismatch, that is, they are either too large or too small to meet the diverse sampling needs. For large-scale soil collection devices, although they have the ability to penetrate deep into the soil layer and collect a large number of soil samples, this is also accompanied by significant portability and operational complexity. Such large devices usually require professional transportation tools to move, and the setup and debugging at the sampling site are also extremely cumbersome, which places high demands on the operator's technical level and physical strength. At the same time, they may also have a certain impact on the environment of the sampling area due to their large size, limiting their flexibility and wide range of use.

[0004] In contrast, small soil collection devices, while portable and quickly deployable, are severely limited in their sampling capabilities. They often struggle to reach deeper into the soil, making them inadequate for research requiring deep soil information. Furthermore, small devices can compromise the accuracy and reliability of subsequent analytical results due to insufficient or unrepresentative sampling. Utility Model Content
