[0027] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them.

[0028] like Figure 1-5 As shown, the present embodiment proposes a contaminated soil remediation device, comprising a bottom plate 1, a push handle 2 fixedly connected to the outer wall of the bottom plate 1, a mixing box 3 fixedly connected to the top wall of the bottom plate 1, a feed pipe 4 fixedly connected to the top wall of the mixing box 3, and further comprising:

[0029] A fixing frame 12 is fixedly connected to the top wall of the bottom plate 1. A first motor 13 is fixedly connected to the inner wall of the fixing frame 12. A driving gear 14 is fixedly connected to the output end of the first motor 13. An end of the driving gear 14 away from the output end of the first motor 13 is fixedly connected to a main rotating rod 19, and the main rotating rod 19 is rotatably connected to the mixing box 3.

[0030] The stirring assembly includes a slider 18 symmetrically slidably connected to the inner wall of the mixing box 3, a secondary rotating rod 16 is rotatably connected between the symmetrical sliders 18, and a connecting frame 27 is rotatably connected to the outer wall of the secondary rotating rod 16, and the connecting frame 27 is fixedly connected to the slider 18, and the connecting frame 27 is fixedly connected to the driving gear 14. The outer wall of the secondary rotating rod 16 is fixedly connected with a uniformly distributed stirring plate 17, and the outer wall of the secondary rotating rod 16 is fixedly connected to the driven gear 15, and the outer wall of the driven gear 15 is meshed with the outer wall of the driving gear 14. The mixed material is placed in the mixing box 3 through the feeding pipe 4, and then the first motor 13 is started, and the mixing material is put into the mixing box 3 through the feeding pipe 4. The output end of the first motor 13 drives the driving gear 14 and the connecting frame 27 to rotate, thereby driving the driven gear 15 and the auxiliary rotating rod 16 to rotate, and then driving the stirring plate 17 to rotate. At this time, the stirring plate 17 and the auxiliary rotating rod 16 are in revolution, thereby realizing revolution stirring. At the same time, the rotation of the driving gear 14 and the meshing between the driven gear 15 will drive the driven gear 15 to rotate, thereby driving the auxiliary rotating rod 16 and the stirring plate 17 to rotate. The revolution and rotation of the stirring plate 17 are combined to fully disrupt the flow trajectory of the mixed materials during mixing, thereby achieving full mixing of the mixed materials and accelerating the mixing speed;

[0031] The lifting and adjusting component is arranged on the outer wall of the base plate 1 .

[0032] like Figure 5As shown, as a preferred embodiment, on the basis of the above method, further, the lifting and adjusting component includes a second motor 22 fixedly connected to the outer wall of the base plate 1, and the output end of the second motor 22 is fixedly connected to the screw 23, and the end of the screw 23 away from the output end of the second motor 22 is rotatably connected to the first side plate 20, and the first side plate 20 is fixedly connected to the base plate 1, and the outer wall of the screw 23 is threadedly connected to the lifting plate 24, and the lifting plate 24 is slidably connected to the first side plate 20, and the outer wall of the lifting plate 24 is fixedly connected to the lifting frame 25, and the inner wall of the lifting frame 25 is provided with an electric crushing wheel 26. By starting the second motor 22, the screw 23 is driven to rotate by the output end of the second motor 22, and the lifting plate 24 is driven by the threaded cooperation between the screw 23 and the lifting plate 24 to drive the lifting frame 25 to slide in the first side plate 20 and the second side plate 21, thereby adjusting the depth of the soil that the electric crushing wheel 26 can turn over, with high flexibility.

[0033] like Figure 2 As shown, as a preferred embodiment, on the basis of the above method, further, the outer wall of the mixing box 3 is fixedly connected to a water pump 8, the water inlet of the water pump 8 is fixedly connected to a feed pipe 7, and the end of the feed pipe 7 away from the water inlet of the water pump 8 is fixedly connected to the mixing box 3, the water outlet of the water pump 8 is fixedly connected to a discharge pipe 9, the end of the discharge pipe 9 away from the water outlet of the water pump 8 is fixedly connected to a hollow tube 10, and the outer wall of the hollow tube 10 is fixedly connected to uniformly distributed nozzles 11. The repair liquid formed after the mixed materials are mixed is discharged through the discharge pipe 9, transported to the hollow tube 10 through the water pump 8 and the feed pipe 7, and sprayed out through the nozzle 11, and at the same time, the electric crushing wheel 26 turns the soil.

[0034] like Figure 5 As shown, as a preferred embodiment, on the basis of the above method, further, the outer wall of the bottom plate 1 is fixedly connected to the second side plate 21, and the second side plate 21 is slidably connected to the lifting plate 24. The first side plate 20 and the second side plate 21 can effectively improve the stable movement of the lifting frame 25 and enhance the structural stability.

[0035] like Figure 1-2 As shown, as a preferred embodiment, on the basis of the above method, further, the outer wall of the base plate 1 is fixedly connected to a symmetrically distributed rotating frame 5, and the outer wall of the rotating frame 5 is rotatably connected to a traveling wheel 6, and the equipment moves through the traveling wheel 6.

[0036] Specifically, when the device for repairing contaminated soil is in use: first, the mixed material is placed in the mixing box 3 through the feed pipe 4, and then the first motor 13 is started, and the output end of the first motor 13 drives the driving gear 14 and the connecting frame 27 to rotate, and then drives the driven gear 15 and the auxiliary rotating rod 16 to rotate, and then drives the stirring plate 17 to rotate. At this time, the stirring plate 17 and the auxiliary rotating rod 16 are in orbital revolution, thereby realizing orbital stirring. At the same time, the engagement between the driving gear 14 and the driven gear 15 will drive the driven gear 15 to rotate, and then drive the auxiliary rotating rod 16 and the stirring plate 17 to rotate. The combination of the orbital revolution and the rotation of the stirring plate 17 fully disrupts the flow trajectory of the mixed material during mixing, thereby achieving sufficient mixing of the mixed material, The mixing speed is fast, and the repair liquid formed after the mixed materials are mixed is discharged through the discharge pipe 9, transported to the hollow tube 10 through the water pump 8 and the feed pipe 7, and sprayed out through the nozzle 11. At the same time, the electric crushing wheel 26 turns the soil. If it is necessary to process soil at different depths, it is only necessary to start the second motor 22, and drive the screw 23 to rotate through the output end of the second motor 22. The threaded fit between the screw 23 and the lifting plate 24 drives the lifting plate 24 to drive the lifting frame 25 to slide in the first side plate 20 and the second side plate 21. The first side plate 20 and the second side plate 21 can effectively improve the stable movement of the lifting frame 25, enhance the structural stability, and thus adjust the depth to which the electric crushing wheel 26 can turn the soil, with high flexibility.

[0037] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
