At this time, the movement of the roller 704 will drive the roller 704 to move and rotate, the rotation of the roller 704 will drive the rotating column 703 to rotate, and the rotation of the rotating column 703 will drive the flip plate 705 to rotate. The rotation or movement of the connecting rod 702, the rotating column 703, and the flip plate 705 can further activate the contaminated soil inside the material tank 3, improve the effect of heating the contaminated soil, and improve the device's effect on contamination. In order to improve the speed of soil repair and reduce the repair time, the stirring mechanism 7 also includes a positive plate 706, a connecting column 707, a soil turning box 708, and an elastic telescopic rod 2 709.

[0017] Working principle: when the device is started, the worker puts the soil to be repaired into the interior of the material tank 3 through the earth-entry door 4. When all the soil is placed in the interior of the material tank 3, the motor 2 will start, and the output end of the motor 2 will drive the reciprocating screw 601 to rotate. The rotation of the reciprocating screw 601 will drive the rotating ball 602 to rotate, but the rotating ball 602 is restricted by the overall parts. At this time, the rotating ball 602 can only move up and down reciprocatingly through the reciprocating groove on the surface of the reciprocating screw 601. The reciprocating movement of the rotating ball 602 will drive the heating rod 603 to move up and down reciprocatingly, and the movement of the heating rod 603 will drive the heat-conducting ring 604 to move up and down reciprocatingly. At this time, the reciprocating up and down movement of the heating rod 603 and the heat-conducting ring 604 can heat the soil at different depths inside the material tank 3, so that the soil inside the material tank 3 is heated evenly, and the heating speed of the soil is increased. Soil heating can increase the soil temperature, thereby accelerating the dissolution of some heavy metals in the soil. The reciprocating screw 601 drives the rotating block 602 to move, and the rotating block 602 drives the heating rod 603 to move. The movement of the heating rod 603 drives the heat-conducting ring 604 to move. The movement of the heat-conducting ring 604 drives the column 605 to move. After the column 605 moves upward for a certain distance, the column 605 contacts and squeezes the L block 607. The squeezing force on the L block 607 compresses the elastic telescopic rod 609, so that the elastic telescopic rod 609 is retracted. At this time, the L block 607 moves upward. The movement of the L block 607 opens the surface opening of the catalyst box 606, so that the catalyst inside the catalyst box 606 can flow out through the opened opening. The movement of the L block 607 causes the catalyst to flow out indirectly, which can improve the efficiency of the device in repairing contaminated soil, and make the removal of heavy metal substances in the soil more efficient and rapid. The indirect outflow of the catalyst can save the cost of repairing the soil by the device.

[0018] When the device is in use, a worker puts the soil to be repaired into the material tank 3 through the soil entry door 4, and then the motor 2 is started, and the output end of the motor 2 drives the reciprocating screw 601 to rotate. The rotation of the reciprocating screw 601 drives the rotating block 701 to rotate. At this time, the rotation of the rotating block 701 drives the connecting rod 702 to rotate, and the rotation of the connecting rod 702 drives the rotating column 703 to rotate and move. The rotation of the rotating column 703 drives the roller 704 to move. During the movement of the roller 704, the circumferential surface of the roller 704 is in contact with the inner surface of the material tank 3. The wall will produce friction, at this time the movement of roller 704 will drive roller 704 to move and rotate, the rotation of roller 704 will drive rotating column 1 703 to rotate, the rotation of rotating column 1 703 will drive flip plate 705 to rotate, the rotation or movement of connecting rod 1 702, rotating column 1 703, flip plate 705 can make the contaminated soil inside the tank 3 further active, improve the effect of heating the contaminated soil, improve the speed of the device to repair the contaminated soil, and reduce the repair time. When the reciprocating screw 601 rotates, the reciprocating screw 601 will drive the rotating circle The movement of the rotating circular block 602 will drive the heating rod 603 to move, the movement of the heating rod 603 will drive the heat-conducting ring 604 to move, the movement of the heat-conducting ring 604 will drive the positive plate 706 to move up and down, the up and down reciprocating movement of the positive plate 706 will drive the connecting column 707 to move up and down, the up and down reciprocating movement of the connecting column 707 will drive the soil-turning box 708 to move up and down, at this time, when the soil-turning box 708 moves downward, the soil-turning box 708 can retain part of the soil inside itself, and then when the soil-turning box 708 rises and turns the soil-turning box 708 up and down, the soil-turning box 708 moves up and down. After the bottom of 08 is no longer in contact with the soil inside the material tank 3, the soil inside the soil turning box 708 will squeeze the soil turning box 708 through its own gravity. At this time, the soil turning box 708 will rotate with the connecting column 707 as the center. The rotation of the soil turning box 708 will cause the soil inside the soil turning box 708 to fall to a position close to the catalyst box 606, and the catalyst dropped from the catalyst box 606 can contact it, which can increase the contact area between the soil inside the material tank 3 and the catalyst, improve the repair efficiency of the soil inside the device, and avoid a small amount of soil not contacting the catalyst, thereby reducing the repair speed and effectiveness.
