Abstract

The invention provides an original-state soil sampling device. The invention relates to a soil sampling device and particularly relates to the original-state soil sampling device. The invention aims to solve the problem that the conventional soil sampling device cannot be used for sampling soil with an original state and has a larger sampling error. The original-state soil sampling device disclosed by the invention comprises a soil borer and a platy shovel. The soil borer comprises a soil borer handle and a wedged drilling pipe; the lower end of the soil borer handle is fixedly connected with the upper end of the wedged drilling pipe; the platy shovel comprises a platy shovel handle and a platy shovel head; the lower end of the platy shovel handle is fixedly connected with the upper end of the platy shovel head; and the front face of the platy shovel head can be tightly matched with the section of the wedged drilling pipe. The original-state soil sampling device disclosed by the invention is used for sampling the soil with the original state.

Description

technical field [0001] The invention relates to a soil sampling device, in particular to an undisturbed soil sampling device. Background technique [0002] Soil sampling is one of the important basic tasks for scientific and technological workers engaged in environmental and ecological research. Accurate and appropriate collection of soil or sediment at different depths is directly related to the accuracy of related research and reliability of data. General soil sampling devices are mainly for Mineral soil with low organic matter content, it is difficult to cut the solid organic matter layer or plant root system of organic soil. Although some samplers with small diameter can barely insert into the soil, the sampling volume is small, and the characteristics of the soil profile are difficult to distinguish. Due to the larger contact area of ​​the sampler with the soil surface, the insertion resistance also increases, and the compression of the soil during sampling is inevitabl...
