Original-state soil sampler

Abstract

The invention relates to an original-state soil sampler comprising a soil sample collecting system and a soil sample pushing system. The original-state soil sampler is characterized in that the soil sample collecting system is formed by connecting a manual handle, an extension rod and a sampling head; the soil sample pushing system is formed by a shoving screw, a shoving rod, a shoving base and a shoving sheet, wherein the shoving screw is connected with the shoving rod inside the extension rod, and the shoving sheet is located inside the sampling head. In the invention, the sampling amount for one time can meet the requirement for monitoring regular pollutant index in soil, thereby greatly improving the sampling efficiency; the sampling head can be easily pushed out of the soil sample so as to ensure convenient and simple discharging process; the sample can be directly pushed out of the sampling head by the shoving sheet without using consumptive materials such as a circular ring, and the like, thereby saving resources; and the original soil level can be maintained and the sampling effect is ensured by controlling the whole process of sampling and discharging effectively.

Description

Technical field [0001] The invention relates to a sampler that can collect soil from farmland, vegetable field, contaminated field and the like. Background technique [0002] In recent years, with the rapid development of our country’s economy, people’s living standards have gradually improved, but at the same time, human production and life have also brought certain negative effects to the environment on which they depend, and soil environmental quality issues are one of them. Focus. As an important environmental medium, soil is very different from the atmosphere, water and other media. The fluidity of soil is small, and the migration and transformation rate of pollutants after entering the soil is relatively slow. Once contaminated, it will be difficult to repair. my country has a large population and a small land area per capita (only 29% of the world’s average per capita). The overall situation of soil pollution is quite severe, and the soil environmental quality is showing a...

Problems solved by technology

[0005] Aiming at the problems encountered in the use of the existing soil sampler: the original layer of the soil is changed during sampling, the depth of collection is not well controlled, the sampling equipment is inconvenient to carry and the sample is unloaded; the present invention provides an undisturbed soil sampler, It can ensure that the collected soil samples are not polluted during sampling, and at the same time, it can also ensure that the original layers of the soil are not disturbed, so as to achieve the purpose of collecting undisturbed soil
