Vehicle-mounted in-situ magnetic field decontamination device for heavy metal contaminated soil with retractable baffle

A vehicle-mounted in-situ magnetic field decontamination device for heavy metal contaminated soil with a retractable baffle, comprising a magnetic particle extraction mechanism, a magnetic particle recovery assembly, a lifting regulator, and an agricultural machinery frame body, wherein the magnetic particle extraction mechanism comprises a mounting frame, a plurality of magnetic rods, and a retractable baffle assembly;

• the mounting frame is in a shape of a closed loop, and the plurality of magnetic rods move circumferentially along the closed loop of the mounting frame and are configured to adsorb magnetic particles in the heavy metal contaminated soil in a slurry state, the magnetic particles are configured to adsorb heavy metals in the heavy metal contaminated soil, a lower end of the mounting frame and a lower end of the lifting regulator are hinged with the agricultural machinery frame body, and an upper end of the mounting frame is supported by the lifting regulator;
• the magnetic particle recovery assembly is arranged on the agricultural machinery frame body and below the upper end of the mounting frame;
• the retractable baffle assembly comprises baffle springs and non-magnetic baffles arranged at free ends of the baffle springs, and the non-magnetic baffles and the baffle springs each sleeve a corresponding one of the magnetic rods;
• the mounting frame is provided at a middle part thereof with a turn-over channel for the retractable baffle assembly to move, the turn-over channel are provided at both sides thereof with compression flaps, and the compression flaps are arranged at a lower side of the upper end of the mounting frame;
• an ejection flare configured to allow the ejection of the non-magnetic baffles is formed between tilted free ends of the compression flaps on both sides, the non-magnetic baffles abut against respective compression flaps after fully extending out, and are compressed to retreat by the compression flaps along with movement of the magnetic rods.
