Soil is the basis of agricultural production, soil analysis work is required to be carried out when the soil is found to be fine, plant nutrition and crop fertilization are researched, and the soil analysis plays a role in carrying out soil general survey, carrying out soil and crop nutrition diagnosis, guiding crop formula fertilization and promoting agricultural production for many years. The agricultural industry needs to study, understand and analyze the main body of the soil, the collection of soil samples is a necessary and first task, and the collection of representative samples is a prerequisite for the measurement result to faithfully reflect the objective conditions of the area or plot represented by the representative sample. As an important ring of soil analysis work, the collection of soil samples relates to the correctness of an analysis result and the correct and fidelity sampling, on one hand, the representativeness of the samples can be improved, errors can be reduced, on the other hand, the process from sampling to result obtaining can be shortened, the representativeness of the soil samples can be mastered and controlled according to the basic conditions of soil types, terrain and landforms, production conditions, crop growth conditions and the like, the original sampling technology also provides methods and requirements on aspects such as distribution points, sampling depth, the number of soil samples and the like, and the number of the sampling points can be calculated and determined even according to a formula n (CV/m). For soil analysis, people usually pay attention to indoor analysis, focus on improvement and improvement of analysis means and test methods, and pay less attention to fidelity of outdoor sampling. The distortion of soil sample collection brings great randomness to sampling, and meanwhile, inconsistency of data result comparison is caused. The method is a disadvantage in sampling and analyzing work, and the soil sample is collected by adopting an earth boring method and a cutting ring method at present, wherein the soil sample collected by the earth boring method is mostly used for measuring the physical, chemical and biological properties of the soil, and the soil sample collected by the cutting ring method is mostly used for measuring the volume weight of the soil.

Present soil sample collector is gathering after the soil sample, and inconvenient taking out the soil sample in the sampling tube, may have remaining soil sample in the sampling tube, so when taking a sample next time, can cause soil sample analysis accurate inadequately.
