[0002] Farmland soil pollution refers to the phenomenon that due to human factors, certain substances enter the surface soil of the land, causing changes in the chemical, physical and biological properties of the soil, thereby affecting the function and effective use of the soil, endangering public health or damaging the ecological environment; the main sources of farmland soil pollution are improper use of fertilizers and pesticides, soil erosion, etc., among which excessive use of fertilizers will lead to the accumulation of nutrients in the soil and destroy the ecological balance of the soil, while excessive use of pesticides will cause residues to enter the soil and cause poisoning to the soil ecosystem. Soil and water loss and wind erosion will weaken soil fertility and affect water quality;

[0003] In the prior art, soil remediation is generally done by manually spraying remediation agents directly onto the soil. However, insufficient absorption of the remediation agent will cause the soil to clump and be unable to spread to the surrounding soil; the remediation agent will remain inside the clump of soil. There are also some mechanized remediation devices on the market, but they generally require manual transfer of the soil into the equipment, and then backfilling it into the field after the remediation is completed. This method requires a large amount of earthwork and has defects. Summary of the invention

[0056] Example 4

[0057] This embodiment provides a soil pollution remediation and treatment device, such as Figure 4 The support assembly 2 shown is a bent hard metal rod; a mounting frame 21 connected to the mechanical equipment is provided at the end of the metal rod; a support frame 22 is provided on the side of the metal rod close to the driving assembly 5 for supporting the pipeline of the liquid supply assembly 3; the pipeline of the liquid supply assembly 3 is a flexible tube, which passes over the top of the treatment assembly 1 and is connected to the connector 42; the flexible tube can be bent into a required shape as needed, and the support frame 22 can support the middle part of the flexible tube to avoid downward deviation due to excessive weight and contact with the outermost rolling ring 11 of the treatment assembly 1, affecting the normal operation of the device.

[0058] In this embodiment, a cylindrical support is provided at the end of the metal rod of the support assembly 2 to provide a base for the drive assembly 5 to be easily installed; the drive assembly includes a motor and a reducer to provide driving force for the connecting shaft 134; after the support assembly 2 and the treatment assembly 1 are assembled, an angle of 15-30° is formed between the metal rod and the treatment assembly 1. Due to the existence of the angle, during the movement of the device, the output direction of the output end is at an obtuse angle to the metal rod of the support assembly 2, so the spilled soil and repair agent will not fall into the soil taking area of ​​the treatment assembly 1.

[0059] The treatment component 1 of the present invention includes three layers from the outside to the inside. In actual use, the repair liquid is pre-prepared according to the composition of the soil pollutants and is temporarily stored in the material box. Then, the liquid supply component 3 is connected to the material box, and the repair liquid in the material box can be transported to the treatment component 1 through the liquid supply component 3 through the pressurizing device.

[0060] At the beginning of the repair operation, the support component 2 is connected first through external mechanical equipment such as tractors and agricultural machinery; the entire treatment component 1 is driven by the mechanical equipment to reciprocate back and forth in a certain area (the movement distance does not exceed 2m). During the movement, the treatment component 1 relies on its own weight to squeeze the blocky soil. After filtering by the first filter structure and the second filter structure, the crushed soil particles that meet the requirements can enter the interior of the treatment component 1, and the driving component 5 drives the connecting shaft 134 to rotate, thereby driving the partition 133 to move, so that the granular soil enters the hollow part through the diversion hole 135; the opening and closing door 43 is controlled to remain closed, and the repair liquid is injected through the liquid supply component 3; after the soil absorbs the repair liquid, the opening and closing door 43 is controlled to open; the driving component 5 increases the rotation speed so that the soil and the repair liquid can be output to the side of the original site through the output port; after completing the repair work of one area, it can be moved to the next area for reciprocating movement, and so on and so forth until the repair work of all plots is completed.

[0061] Compared with manual restoration, this embodiment greatly improves efficiency and reduces earthwork workload compared with traditional mechanical equipment; the mixed soil is fully absorbed and splashed back to its original place, which is not likely to cause soil compaction. The splashing method can also make the treated soil more evenly distributed in the original plot.

[0062] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
