Description

Technical Field

[0002] Common forms of soil pollution include inorganic pollution and organic pollution. Among them, inorganic pollution is most significant and harmful to heavy metal elements, and organic pollution is most significant and harmful to fertilizers, pesticides, insecticides and herbicides. Soil remediation refers to the use of physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in the soil to reduce their concentration to an acceptable level, or to convert toxic and harmful pollutants into harmless substances. Common soil remediation agents are used for treatment, and corresponding dosing devices are required. Publication No. CN219944097U discloses a dosing device for soil treatment. By starting the first electric push rod, the first electric push rod adjusts the amount of water extracted by the push disk and adjusts the concentration of the agent, thereby achieving the effect of precise dosing for different soils; the second electric push rod descends, causing the push disk to descend, and the mixed reagents inside the mixing barrel are finally sprayed by the nozzle through the liquid outlet pipe to improve the mixing efficiency of the agent. However, the device achieves drug addition by pushing the disk to move back and forth, and will stop spraying during the rising process. The discontinuous spraying leads to uneven spraying. At the same time, the control of the first electric push rod depends on manual operation, making it difficult to achieve accurate concentration adjustment. Utility Model Content
