Multifunctional rapid detection device for detecting environment soil

Abstract

The invention discloses a multifunctional rapid detection device for detecting environment soil. The multifunctional rapid detection device comprises a shell, wherein the shell is sequentially provided with a soil sample feeding hopper, a soil grinding device and a soil flow distribution device from top to bottom; the soil flow distribution device comprises a rectangular main pipe and three rectangular secondary pipes; soil conveyor belts are arranged at the bottom ends of the three rectangular secondary pipes; a soil component detection device, a soil moisture detection device and a soil potential of hydrogen detection device are arranged below the three conveyor belts respectively; the soil component detection device comprises a near-infrared soil nutrient rapid detection instrument; a gas chromatograph is arranged at one side of the soil moisture detection device. According to the multifunctional rapid detection device provided by the invention, the potential of hydrogen of the soil, nutrients of soil solids, the moisture content of the soil and gas properties in the soil can be detected at the same time; the multifunctional rapid detection device has the advantages of completedetection functions, high detection efficiency, semiautomatic detection and labor saving and cost reducing.

Description

technical field [0001] The invention relates to the technical field of soil detection, in particular to a multifunctional rapid detection device for environmental soil detection. Background technique [0002] After weathering, the rocks on the earth's surface are gradually broken into loose mineral particles of various sizes (called parent materials). Soil is formed and evolved under the comprehensive action of various soil-forming factors such as parent material, climate, organisms, topography, and time. The composition of soil is very complex. Generally speaking, it is composed of three phases of solid, liquid and gas such as minerals, organic matter produced by the decomposition of animal and plant residues, water and air. [0003] Soil refers to the loose surface layer of the land surface that is fertile and capable of growing plants. It lies between the atmosphere, lithosphere, hydrosphere and biosphere, and is a unique component of the environment. Soil is composed ...

Problems solved by technology

[0010] (1) Most of the existing devices that are portable and can be detected in the field, due to their small size, can only detect certain properties of the soil, such as certain organic matter and moisture in the soil, and have few functions. If you want to detect soil For most of the functions, a combination of multiple detection devices is required, which not only has a large error, but also takes a long time;

[0011] (2) At present, the more comprehensive testing of soil is carried out in the laboratory. In the laboratory, the soil samples need to be preserved and brought to the laboratory. If the soil is not well preserved, the test results will be quite different from the real value. , and when testing in the laboratory, because multiple properties of the soil need to be detected, the detection takes a long time, it takes a long time to wait, the detection efficiency is low, and the cost of various reagents is also relatively high. bigger
