Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling, in particular to a foldable automatic sealing soil sampler. Background Art

[0002] With the improvement of environmental protection awareness and the refinement of agricultural production, the monitoring and analysis of soil quality, composition, pollutants, etc. have become increasingly important. Traditional soil sampling methods often have problems such as cumbersome operation, low efficiency, and easy contamination of samples, which cannot meet the needs of modern soil science research and application. Therefore, a foldable automatic sealing soil sampler is needed.

[0003] A Chinese patent discloses a soil sampler (authorization announcement number CN204789028U). The patented technology uses a telescopic sleeve structure sampler. When carrying, the handle is folded upward, and the spring positioning pin is pressed to push the sampling rod I and the sampling rod II into the sampling tube at the same time, which reduces the length of the sampler and is easy to carry. The sampling port on the side of the soil sampling tube can ensure that the soil can easily enter the soil sampling tube. At the same time, the use of a scraper can scrape off the soil that is difficult to remove.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the existing foldable automatic sealing soil sampler cannot quickly install and disassemble the extraction pump during use, resulting in a long equipment downtime, affecting the continuous and stable operation of the equipment, and increasing the labor intensity of the operator.
