Soil pollution vertical detection device

Abstract

The invention provides a soil pollution vertical detection device, belongs to the technical field of soil treatment, and solves the technical problems that an existing detection device is inaccurate in detection result, easy to damage and the like. The soil pollution vertical detection device comprises a lifting mechanism, a plurality of detection mechanisms are arranged on the lifting mechanism, each detection mechanism comprises a drill rod, a cavity is formed in a rotating rod, a rotating shaft is rotationally connected in the cavity, the upper end of the rotating shaft extends out of the cavity, the upper end of the rotating shaft is connected with the lifting mechanism, and a plurality of sets of rotating sleeves which are symmetrical vertically are arranged on the rotating shaft. The rotating sleeve is rotationally connected with the rotating shaft, symmetrical telescopic rods are fixed to the outer side of the rotating sleeve, the other end of each telescopic rod is connected with a sampling barrel, the outer side of each telescopic rod is sleeved with a tension spring, and a plurality of eccentric wheels matched with the sampling barrels are arranged on the rotating shaft. The device has the advantages that stratified sampling is realized, the accuracy of the detection result is improved, and the detection part is protected.

Description

Technical field [0001] The present invention belongs to the field of soil remediation technology, relates to a detection device, in particular a vertical soil contamination detection means. Background technique [0002] The soil is extremely important for human survival precious natural resources, but with the rapid development of industry and agriculture, the sharp population growth, garbage thrown away, irrigation, Tailing and a series of environmental safety soil problems It has become increasingly prominent. Crops, animals will be directly affected, indirectly affecting the health of human beings. Currently the surface soil contamination with other factors such as rainfall or irrigation has spread to the deep soil, soil heavy metals, excess NPK, pH, extreme environment will have an impact on soil. [0003] In the prior art, the detection of the degree of contamination of soil is vertically fixed to a particular place detecting means is detected by extracting soil samples, so ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the detection of the vertical soil pollution degree is to fix the detection device in a specific place and take soil samples for detection, which will easily cause confusion of the soil layer and affect the accuracy of the soil detection results, and directly The detection device is easy to cause damage to the detection device during the movement to the deep soil because the detection part needs to be in contact with the soil
