Sampling equipment for contaminated soil regeneration

Abstract

The invention relates to the technical field of soil regeneration, and discloses sampling equipment for contaminated soil regeneration. A mounting seat is fixedly connected to the upper part of the front surface of a body, a metal part is movably connected to the top end of the mounting seat, and a double-screw rod is movably connected to the inner side of the left end of the metal part. Accordingto the sampling equipment for the contaminated soil regeneration, the double-screw rod rotates anticlockwise to drive a screw thread to operate along with the double-screw rod, the screw thread and asliding piece are driven by mutual friction under the action of internal threads, the screw thread drives the sliding piece to reciprocate up and down, a driving piece changes from an initial flat state to an extraction state and extrudes a chemical agent, the sliding piece extrudes a strong spring upwards to operate, when the sliding piece presses the strong spring downwards to reach a limit value, a compressed state is changed into a stretching state, the acceleration effect is achieved on the strong spring which slowly rises to the double-screw rod operating upwards, and the equipment is enabled to achieve the effects of mechanical sampling, automatic liquid spraying, high efficiency and high automation degree.

Description

technical field [0001] The invention relates to the technical field of soil regeneration, in particular to a sampling device for regeneration of polluted soil. Background technique [0002] Contaminated soil regeneration treatment mainly refers to the use of physical, chemical, biological, and ecological principles. Generally, contaminated soil remediation can be divided into several categories: phytoremediation, microbial remediation, chemical remediation, physical remediation, and comprehensive remediation. With the popularization of scientific planting models, the study of soil quality is becoming more and more important. A comprehensive understanding of the soil composition of each soil layer can help people use land resources more effectively. [0003] During the long-term use of the soil, the soil is often polluted due to the destructive use of people and the discharge of a large amount of pollutants. In order to ensure the normal use of the soil, it is usually necessa...

Problems solved by technology

[0003] During the long-term use of the soil, the soil is often polluted due to the destructive use of people and the discharge of a large amount of pollutants. In order to ensure the normal use of the soil, it is usually necessary to restore and regenerate the soil. Sampling is required for soil regeneration. Now Some soil sampling is mainly divided into manual sampling and mechanical sampling. Manual sampling has high work intensity, high cost and low efficiency, and is time-consuming and laborious. Mechanical sampling equipment is generally complicated and requires constant replacement of samples, which greatly affects work efficiency. A sampling device for the regeneration of contaminated soil emerges at the historic moment
