A multi-point intelligent collection and detection device for polluted soil

Abstract

The invention discloses a contaminated soil multi-point intelligent collection and detection device, and belongs to the technical field of soil detection equipment. The device mainly comprises a detection box body, a soil collection element, an intelligent detection element and a power supply, the soil collection element comprises a collection installation drawer, a telescopic sleeve and a collection head, the lower end of the outer wall of the collection head is sleeved with an annular support, and multiple soil loosening gear rods are evenly arranged at the bottom end of the annular supportin the circumferential direction; through the arrangement of the soil loosening gear rod, soil loosening can be conducted on a to-be-collected detection area, and damage to a drill bit or shortening of the service life of the drill bit due to too hard soil texture is avoided; through the arrangement of the collection head, a spiral collecting piece can be prevented from being exposed all the timeand being bent easily, the soil collecting effect is not affected, and therefore, the detection efficiency is reduced; soil at different depths can be collected at multiple points; and moreover, the contaminated soil multi-point intelligent collection and detection device has the advantages of convenient collection, accurate detection and intelligent integration, and is suitable for large-scale popularization.

Description

technical field [0001] The invention belongs to the technical field of soil detection equipment, and in particular relates to a multi-point intelligent collection and detection device for polluted soil. 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 substances, water, air, microorganisms, etc., and can grow plants. It is composed of organic matter produced by body decomposition, soil organisms, water, air, and oxidized humus. Solid substances include soil minerals, organic matter, and nutrients obtained by microorganisms through light inhibition and sterilization; liquid substances mainly refer to soil moisture; gas is air existing in soil pores; these three types of substances in soil constitute a contradictory Unity, they are interconnected and restrict each other, provide the necessary living conditions for crops, and are the material basis of soil fertility.

Problems solved by technology

[0003] With the development of the times, people's awareness of environmental protection is getting higher and higher. The state encourages people to build municipal gardens, but the existing land is destroyed. In order to better build municipal gardens, people invented soil that can help people understand the status of soil pollution. However, the existing soil collection and detection devices have the following defects: 1) the contaminated soil at different heights of the same sampling point cannot be detected at the same time, resulting in inaccurate detection results; 2) when the soil in the area to be collected is hard 3) When the collection head is not in use, it is always exposed and prone to bending, which affects the soil collection effect, thereby reducing the detection efficiency
