When the soil property is investigated, the soil is cleared up, high-standard farmland construction and long-term positioning test are carried out, the basic soil properties such as pH, EC, organic matter nutrient content and the like of the soil in an investigation area or a test area are firstly investigated. Meanwhile, in the process of scientific research and test, the basic properties of the soil in different soil layers at different time need to be determined according to the test scheme in the long-term test field, so that the soil in the corresponding soil layer needs to be adopted for indoor analysis and test. Soil samples of different soil layers are taken, generally through a soil sampler. The soil sampler is one of agricultural instruments, and the existing soil sampler in the market is generally a handheld stainless steel soil sampler and an electric soil sampler. The hand-held stainless steel soil sampler consists of a drill body, a connecting rod and a handle, wherein the drill body has a cylindrical shape and a square shape. The electric soil sampler is generally provided with a power device and is mainly used in the engineering field with hard geology and deep soil sampling depth. At present, in the development aspect of the handheld stainless steel soil sampler, a scraper is also added. However, in the practical application process, the handheld stainless steel soil sampler cannot be used efficiently, needs great strength to be inserted into soil, and is very labor-consuming to pull out. Meanwhile, soil brought out by the soil drilling device cannot be easily scraped into the sample bag, and sometimes the soil is very hard to stick and can not be scraped cleanly. The common hand-held stainless steel soil sampler has no very accurate calculation on the soil sampling depth, and workers or scientific researchers can only observe and estimate the soil sampling depth in the common soil sampling process.
In addition, current scraper tip is mostly screwed connection, scrapes the head and is mostly the cylinder, or only the tip surface is carved with the screw thread. Although the cylinder scraping head can be conveniently taken down, the cylinder scraping head is easy to lose in practice. Therefore, when a researcher or a worker needs to sample soil for a long-term positioning test site or an engineering construction site, the operation of sampling soil by using the sampler causes low working efficiency and wastes time and labor. Moreover, the scraping is not clean, so that the pollution of different test areas can be caused, the test effect is influenced, and the influence on soil microorganisms, organic pollutants and the like is great particularly when the investigation is carried out.
