The utility model discloses a soil remediation box. Box body, supporting legs are symmetrically arranged on the two sides of the bottom of the box body. A discharge port and a control valve matched with the discharge port are arranged in the center of the bottom of the box body; and a first stirring mechanism and a second stirring mechanism are arranged at the positions, close to the lower end face, in the box body correspondingly, transmission shafts penetrating through the box body are connected to the deviated end faces of the first stirring mechanism and the second stirring mechanism correspondingly, and fixing blocks are symmetrically installed on the two sides of the top of the box body. According to the utility model, the driving motor drives the second bevel gear to operate; the transmission direction is changed through meshing of the first bevel gear; the two rotating shafts operate in opposite directions, so that the first stirring mechanism and the second stirring mechanismrotate in opposite directions, the first convex rods and the second convex rods are distributed in a staggered manner, and the operation directions of the first convex rods and the second convex rodsare opposite, so that soil can be uniformly stirred and fully mixed with remediation liquid, and the purpose of efficient soil remediation is achieved.
