a soil sampler

Abstract

The invention relates to the field of soil sampling devices, in particular to a soil sampler, comprising a fixed sleeve, a soil-taking structure, a water injection structure, a lubricating structure, a bulldozing structure and an air intake structure; the soil-taking structure can drive The water injection structure works, and through the work of the water injection structure, when the soil borrowing structure is working, the soil samples taken from the soil borrowing structure can be injected with water, and the soil samples that need to be taken from the soil can be soaked to reduce the soil hardness. The purpose of this is to speed up the efficiency of soil fetching and facilitate soil fetching. Through the combined use of the fixed sleeve and the soil fetching structure, the power of the feet can be used to achieve rotary soil fetching without repeated rotation of the hands, which can save manpower. , It can also use the power of the feet to accelerate the speed of inserting the soil, and the way of rotating the soil can be further inserted into the interior of the soil quickly, so that it can achieve rapid soil extraction and facilitate soil sampling.

Description

technical field [0001] The invention relates to the field of soil sampling devices, in particular to a soil sampler. 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 interconnected and restrict each other, provide the necessar...

AI Technical Summary

Problems solved by technology

[0003] When sampling soil with low water content and relatively hard soil, due to the lack of water and hardening of the soil, it is difficult for the sampler to enter the interior of the soil for sampling. The sampling work is time-consuming and labor-intensive
