Soil sampling device convenient for rapid sampling

Abstract

The invention relates to the technical field of soil sampling devices, in particular to a soil sampling device convenient for rapid sampling, which comprises a support structure, a positioning structure, a soil loosening structure, an expansion structure, a sampling structure and a driving structure, the soil loosening structure used for loosening soil is connected to the driving structure used for driving the soil loosening structure to rotate, and the soil loosening structure is provided with the expansion structure used for cleaning the soil, so that the soil loosening structure is conveniently driven by the driving structure to be inserted into the soil, and the soil at the bottom end is lifted to the ground through the soil loosening structure; the soil at the top end and the soil at the bottom end are prevented from being mixed, meanwhile, the soil loosening structure expands to abut against the soil on the side wall through the expansion structure, the soil in the holes is effectively prevented from collapsing and falling to the bottom end, the soil sampling quality is further improved, soil at the same position and different depths can be conveniently sampled, and the positioning structure is arranged, so that the sampling depth of each time can be conveniently adjusted, and the sampling efficiency and the sampling quality are greatly improved.

Description

technical field [0001] The invention relates to the technical field of soil sampling devices, in particular to a soil sampling device which is convenient for rapid sampling. Background technique [0002] Soil refers to a layer of loose material on the surface of the earth, which is composed of various granular minerals, organic matter, water, air, microorganisms, etc., and can grow plants. Soil is composed of minerals, animals and plants from weathering of rocks, organic matter produced by the decomposition of microbial residues, soil organisms (solid phase substances), water (liquid phase substances), air (gas phase substances), oxidized humus, etc. Solid matter includes soil minerals, organic matter, and nutrients obtained by microorganisms through photoinhibition and sterilization. Liquid matter mainly refers to soil moisture. Gas is the air that exists in the pores of the soil. These three types of substances in the soil constitute a contradictory unity. They are i...

Problems solved by technology

[0003] However, when sampling soft soil with less water content, because the soil is soft, when sampling the soil on the top layer and sampling the soil on the bottom layer again, the soil on the top layer will easily fall to the bottom layer. It is not convenient to sample the soil at different depths at the same location, and the quality of sampling will be easily affected after the soil is mixed.
