[0004] In the above-mentioned prior art, although the soil in the inner cylinder frame is eluted by the spray assembly, so that the soil is turned over and eluted while being transported toward the discharge port of the outer cylinder, there is no soil crushing structure in this process. Since the contact area between the bulk soil and the chemical reagent is small, the reaction speed is relatively slow, which directly leads to a decrease in the efficiency of soil remediation. Therefore, in order to increase the rate of soil remediation, it is necessary to add a special soil crushing device based on the existing technology. Utility Model Content
