Description

Technical Field

[0002] Heavy metal pollution and pesticide residue control in soil are one of the most widespread and harmful environmental problems in soil pollution today. Heavy metal pollution and pesticide residue are different from other organic compound pollution. Organic compounds can be purified by microorganisms in nature to reduce or eliminate their harmfulness, while heavy metals are difficult to be degraded by microorganisms. The main source of heavy metal pollution in soil comes from waste emissions from industries such as chemical, electroplating and electronics. High concentrations of heavy metal elements can produce severe toxicity. Unreasonable soil fertilization, drug use, mining, etc. are long-term pollutants in the environment, which can easily affect the ecological structure and functional stability of the soil, causing poisoning or even death of animals and plants, so it is necessary to repair and control the contaminated soil.

[0037] A method for improving an adsorption-type soil improvement device for treating excessive heavy metals, comprising the following steps:

[0038] In the first step, the first rotating shaft 26 is rotated counterclockwise by the servo motor 33. By setting the infusion component, the fertilizer stock solution in the mother liquid tank 28 can be introduced into the fertilizer tank 17 in equal and intermittent amounts to mix with water. By setting the auxiliary mixing component, the stirring rod 46 can be rotated around the axis direction of the second rotating shaft 27 for stirring, and the stirring rod 46 can also be rotated around the axis direction of the third rotating shaft 44 for stirring. The stirring rod 46 can also move up and down to improve the mixing effect of the fertilizer stock solution and water. By setting the water delivery component, the water in the water tank 3 can be introduced into the water outlet box 14 in equal and intermittent amounts and sprayed out through the nozzle on the water outlet box 14. By irrigating with clean water in advance, the surface soil can be moistened, which is conducive to the downward movement of the fertilizer. By setting the rotating component, the water outlet box 14 can be swung left and right to increase the wetting range.

[0039] In the second step, after the preset wetting time, the servo motor 33 is used to rotate the first rotating shaft 26 clockwise. By setting a fertilizer delivery component, the mixed fertilizer liquid can be equally and intermittently introduced into the liquid outlet box 13 and sprayed out through the nozzle on the liquid outlet box 13. By setting a rotating component, the liquid outlet box 13 can be swung left and right to increase the fertilization and elution range.

[0040] When the present invention is used, a proper amount of clean water is injected into the water tank 3 and the fertilizer box 17 through the injection pipe 4, and the servo motor 33 is started to rotate the first rotating shaft 26 and the second gear 25 counterclockwise. When the first rotating shaft 26 rotates counterclockwise, the inner ring of the one-way bearing 37 rotates counterclockwise accordingly. At this time, the inner ring and the outer ring of the one-way bearing 37 are locked with each other, and the reciprocating screw 23 rotates counterclockwise accordingly, and finally the lifting block 36, the lifting rod 22, the water outlet rod 38 and the water outlet plug 39 move up and down. During the up and down movement of the water outlet plug 39, the clean water in the water tank 3 will be sucked into the water delivery cylinder 40 through the first conduit 5, and then squeezed into the water outlet box 14 through the second conduit 15 and moistened the soil through the nozzle on the water outlet box 14, which is conducive to the subsequent downward movement of the fertilizer;

[0041] When the second gear 25 rotates counterclockwise, the first gear 24 is meshed with the second gear 25, so that the first gear 24, the second rotating shaft 27, the transmission block 34 and the rotating disk 9 (attached Figure 1 When the turntable 9 rotates clockwise, the second round rod 10 rotates clockwise around the axis of the turntable 9, and the second round rod 10 contacts the first round rod 8. Figure 7 The middle fertilizer delivery plug 48 abuts against one end of the fertilizer delivery tube 6 and will not continue to move to the left, so that the second round rod 10 first contacts with the first round rod 8 and finally separates from each other. During the contact between the second round rod 10 and the first round rod 8, the moving block 49 and the infusion plug 51 move to the left synchronously, the second spring 53 is compressed, and the mother liquid in the infusion tube 55 is squeezed into the fertilizer box 17 through the fifth conduit 19. When the second round rod 10 and the first round rod 8 separate from each other, the elastic force generated by the compression of the second spring 53 can reset the moving block 49 and the infusion plug 51, so that the mother liquid in the mother liquid box 28 is sucked into the infusion tube 55 through the sixth conduit 20;

[0042] When the transmission block 34 rotates and the lifting rod 22 moves up and down, because the transmission block 34 is rectangular and always cooperates with the transmission groove 41, and the lifting rod 22 is rotatably connected to the lifting block 36, the lifting rod 22 can rotate synchronously with the transmission block 34. During the rotation of the lifting rod 22, the stirring rod 46 can rotate, and during the up and down movement of the lifting rod 22, the stirring rod 46 moves up and down accordingly. By providing the third gear 45 and the rack 43, the stirring rod 46 can rotate around the axis of the third rotating shaft 44, so that the stirring rod 46 can move up and down while also rotating horizontally and swinging up and down, so that the mother liquid and clean water in the fertilizer box 17 can be evenly mixed and stirred, thereby improving the mixing effect;

[0043] After a period of time, the servo motor 33 is started to rotate the first shaft 26 and the second gear 25 clockwise. When the first shaft 26 rotates clockwise, the inner ring of the one-way bearing 37 rotates clockwise accordingly. At this time, the inner ring and the outer ring of the one-way bearing 37 rotate idly, and the reciprocating screw 23 cannot rotate, that is, the lifting block 36 and the lifting rod 22 do not move up and down, and no clean water will be sprayed out of the water outlet box 14. When the second gear 25 rotates clockwise, the first gear 24 is meshed with the second gear 25, so that the first gear 24, the second shaft 27, the transmission block 34 and the turntable 9 (attached Figure 1 When the turntable 9 rotates counterclockwise, the second round rod 10 rotates counterclockwise around the axis of the turntable 9, and the second round rod 10 contacts the first round rod 8. Figure 7 The middle moving block 49 abuts against the right end of the moving groove 54 and cannot continue to move rightward in the moving groove 54, so that the second round rod 10 first contacts with the first round rod 8 and finally separates from each other. During the contact between the second round rod 10 and the first round rod 8, the moving block 49, the infusion tube 55, the square rod 7, and the fertilizer plug 48 will move rightward synchronously, and the first spring 50 will be compressed, so that the fertilizer liquid stirred and mixed evenly in the fertilizer box 17 can be sucked into the fertilizer tube 6 through the fourth conduit 18. When the second round rod 10 is no longer in contact with the first round rod 8, the elastic force generated by the compression of the first spring 50 can reset the moving block 49, the infusion tube 55, the square rod 7 and the fertilizer plug 48, so that the fertilizer liquid sucked into the fertilizer tube 6 can be squeezed into the liquid outlet box 13 through the third conduit 16 and sprayed out through the nozzle on the liquid outlet box 13 to improve the soil;

[0044] When the turntable 9 rotates counterclockwise or clockwise, the second round rod 10 will slide inside the auxiliary frame 11, so that the auxiliary frame 11 can swing left and right, and then the rotating rod 12, the liquid outlet box 13 and the water outlet box 14 can rotate left and right, so as to increase the range of clean water wetting and subsequent liquid spraying improvement and improve the use effect. The threaded rod 32 can be rotated by rotating the hand wheel 29, so that the threaded block 30 can be moved back and forth, so as to adjust the rotation radius of the second round rod 10. When the rotation radius of the second round rod 10 is larger, the volume of its mother liquid sucked into the fertilizer box 17 at a time is larger, the volume of the fertilizer liquid sucked out at a time is also larger, and the range of clean water wetting and liquid spraying improvement is larger. The smaller the rotation radius of the second round rod 10 is, the smaller the volume of its mother liquid sucked into the fertilizer box 17 at a time, the smaller the volume of the fertilizer liquid sucked out at a time is also smaller, and the range of clean water wetting and liquid spraying improvement is smaller, which can meet the use requirements in different situations.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
