The current soil sampling method mainly comprises two forms of excavation and exploratory well, exploratory groove direct sampling and sampler sampling, wherein the sampler sampling is simple, convenient and practical, has small damage to the earth surface environment, and is the most common sampling mode. In the outdoor sampling process, the power of the sampler mainly comprises manpower and machinery, and the drill bit is pressed into or screwed into the soil by utilizing the power to sample. The mechanical sampling operation is fast, the sampling depth is large, the mechanical sampling operation can adapt to various soil qualities, but the mechanical sampling operation is large in size and laborious to carry, and the mechanical sampling operation is relatively difficult especially in regions where some vehicles cannot reach. The manpower sampler can meet the soil sample collection requirements under various environments, so that more manpower samplers are used in shallow soil collection.

In order to make the soil sample closest to the natural condition of soil, the traditional manual sampler mainly takes a drill cylinder with a cutting ring as a sampling tool when raw soil is sampled, and a scraper is used for separating the sample from the drill cylinder. Soil in the drill cylinder is difficult to take out directly after drilling due to compaction, the integrity of a soil sample is easy to damage when the soil is taken out from the drill cylinder by using a tool, and meanwhile, the complete transfer of the soil in the drill cylinder takes a long time, so that the sampling progress is slow.
