The invention relates to a sleeve-driven closed tooth type fixed-range sampler which comprises a hollow outer sleeve, an inner sleeve assembly movably arranged in the outer sleeve, a supporting frame, a precession handle and an opening and closing handle, the supporting frame is arranged outside the outer sleeve and the inner sleeve assembly, the outer sleeve is fixedly connected with the supporting frame, the precession handle is fixedly connected with the supporting frame, the inner sleeve assembly is movably connected with the supporting frame, the opening and closing handle is fixedly connected with the inner sleeve assembly, petal-shaped sealing teeth are detachably arranged at the bottom of the inner sleeve assembly, when the sealing teeth are located in the outer sleeve, the sealing teeth are in a closed state, and when the sealing teeth stretch out of the outer sleeve, the sealing teeth are in an open state. Compared with the prior art, the sleeve-driven closed tooth type fixed-range sampler has the advantages that the sampling depth and the sample amount can be accurately controlled, the problem of secondary pollution introduced in the sampling process can be effectively avoided, it is ensured that volatile components are not lost, and the sleeve-driven closed tooth type fixed-range sampler has the advantage of being portable to use in the field.
Description
technical field [0001] The invention relates to a soil sampling device, in particular to a casing-driven closed-tooth type fixed-range sampler. Background technique [0002] In order to ensure the rapid development of the economy, our country has used the soil unreasonably for a long time, making the contradiction between population-resources-environment increasingly acute, and the problem of soil quality is gradually receiving common attention worldwide. Soil resources are very fragile resources, which are of great significance to food safety, human health and safety, and even environmental safety. In order to achieve stable agricultural growth, safe and rational use of construction land, and sustainable development of the ecological environment, it is necessary to re-understand the role of soil in The important role of the environment, focusing on the relationship between soil quality and the environment. [0003] In the fields of ecology, soil science, and environmental ...
