In one embodiment, the heated remediation mechanism 500 is installed on the third soil-agitating device 223. Therefore, in the moving process of the moving mechanism 100, the photocatalytic mechanism 300 firstly catalyzes the loosened soil, the adhesive repairing mechanism 400 mixes the soil repairing agent into the soil after photocatalytic treatment, which is to be repaired and is stirred and broken, and finally the heating repairing mechanism 500 heats the soil to be repaired mixed with the repairing agent, so that pollutants in the soil to be repaired can be decomposed as much as possible through the steps of photocatalytic treatment, mixing of the repairing agent, heating and the like, and the soil repairing efficiency is greatly improved.

The photocatalytic mechanism 300 is provided with an ultraviolet lamp, and when the ultraviolet lamp works, the photocatalytic mechanism 300 emits ultraviolet light to irradiate the soil to be repaired, which is stirred and broken by the soil stirring device 220, so that the pollutants in the soil to be repaired are partially decomposed by the ultraviolet light. Particularly, for the petroleum pollutants in the soil, the ultraviolet light can be adopted to well decompose the petroleum pollutants in the soil.

The reagent repairing mechanism 400 is used for storing a soil repairing agent, and after the soil to be repaired is stirred and loosened or the loosened soil is catalyzed by ultraviolet light, the stored soil repairing agent is uniformly mixed into the soil to be repaired. Preferably, the soil remediation agent comprises the following components in parts by mass: 40 parts of farmyard manure, 20 parts of biomass charcoal, 20 parts of bamboo fiber grinding particles, 8 parts of organic acid, 9 parts of proline, 0.5 part of compound microbial agent and 8 parts of compound additive.

In this embodiment, the reagent repairing mechanism comprises a reagent kit and a blocking piece, the blocking piece is slidably connected with the bottom of the reagent kit, and the blocking piece is used for controllably opening or closing a plurality of open pores at the bottom of the reagent kit, so that the soil repairing agent stored in the reagent kit is controllably mixed into the soil to be repaired. Further, the reagent box is of a hollow cylindrical groove-shaped structure with an opening on the side wall. The bottom of the kit is provided with a plurality of openings. The soil remediation agent is stored in the kit through the opening, and after the blocking piece leaves each open pore, the soil remediation agent falls from each open pore under the influence of gravity and is mixed into the soil to be remedied; after the blocking pieces cover the open holes, the soil remediation agent stops falling off and is stably stored in the kit. In one embodiment, the reagent repairing mechanism further comprises a cover body, the cover body is rotatably connected with the reagent kit, and the cover body is used for covering the opening of the reagent kit so as to prevent soil repairing agent from overflowing from the opening of the reagent kit due to vibration in the moving process.

The heating remediation mechanism 500 is mounted with the soil agitation device 220, that is, the heating remediation mechanism 500 may also heat the soil simultaneously as the soil agitation device 220 agitates and loosens the soil. In one embodiment, the heat restoration mechanism 500 is provided only in the third soil agitating device 223. Preferably, there are three heating and repairing mechanisms 500 installed in the first soil-agitating device 221, the second soil-agitating device 222 and the third power device 213, respectively, and the three heating and repairing mechanisms 500 are controlled to be heated simultaneously and synchronously or asynchronously. Therefore, the soil to be repaired can be heated better and faster, and the soil repairing efficiency is improved.

In this embodiment, the heating repair mechanism is a heating wire. The heating and repairing mechanism is arranged along the extending direction of the soil stirring device. For example, the soil stirring device is a spiral blade structure, and the heating wires are arranged on the spiral blade structure in a spiral structure along the spiral blade structure. Therefore, the soil to be repaired is loosened through stirring by the soil stirring equipment, and when the soil to be repaired needs to be heated, the soil to be repaired can be heated by starting the heating wire. It should be noted that the heating wire is wrapped and installed on the soil-agitating device by an insulating heat-resistant material such as resin-bonded or impregnated, coated mica, a glass fiber material, or the like. In other embodiments, the heat repair mechanism may be a heat fin.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
