Description

Technical Field

[0001] The utility model relates to the technical field of plant restoration, in particular to a plant restoration device for heavy metal polluted soil. Background Art

[0002] Heavy metal pollution is the most prominent among inorganic soil pollution. This is mainly because heavy metals cannot be decomposed by soil microorganisms, but are easily accumulated and converted into more toxic methyl compounds. Some even accumulate in the human body at harmful concentrations through the food chain, seriously endangering human health. It can also lead to soil degradation and reduced crop yield and quality. Therefore, the remediation of heavy metal pollution in the soil is of vital importance.

[0003] The Chinese utility model patent with patent application number CN201921428446.9 provides a plant remediation device for heavy metal contaminated soil. By using different plants to sequentially adsorb different types of heavy metal trace elements in the soil in the area, it can absorb various heavy metals multiple times and more effectively solve the heavy metal pollution of the soil.

[0004] However, during use, it was found that when the above-mentioned device controls different plants to rotate to different positions, it drives the rotating shaft through a motor, so that the rotating shaft drives the planting box to rotate through a connecting rod. However, when the plants absorb heavy metals in the soil, the roots of the plants will enter the soil. When the rotating shaft drives the planting box to rotate, the plants will be forcibly pulled. When forced to pull, it will cause greater root damage, which will affect the subsequent survival and adaptability of the plants. Utility Model Content

[0005] In view of the above problems, the utility model provides a heavy metal contaminated soil plant remediation device to solve the problems in the prior art of forcibly pulling plants during transplantation, causing significant root damage and affecting the subsequent survival and adaptability of the plants.

DETAILED DESCRIPTION

[0021] The utility model is further described in detail below with reference to the accompanying drawings and through specific embodiments. The following embodiments are merely illustrative and not limiting of the protection scope of the utility model.

[0022] Embodiment 1: As shown in the attached Figure 1 and attached Figure 2 As shown, a heavy metal contaminated soil plant remediation device comprises a planting box 1, a planting plate 12 is installed in the middle of the planting box 1, and a plurality of planting holes 121 are opened on the planting plate 12;

[0023] A bottom mesh layer 14 is provided at the bottom of the planting box 1 , a planting layer 13 is provided between the planting plate 12 and the bottom mesh layer 14 , and fixing nails 11 are fixedly installed at the bottom of the planting box 1 .

[0024] As can be seen from the above, the planting box 1 is fixed on the heavy metal contaminated soil by the fixing nails 11, and plants that can absorb heavy metal trace elements are planted in the planting box 1. The plants are planted in the planting holes 121 of the planting plate 12 in turn. The root system of the plant continues to develop downward in the planting layer 13. The root system of the plant passes through the bottom mesh layer 14 and enters the soil to be repaired at the bottom, and absorbs the heavy metal trace elements in the soil, thereby repairing the heavy metal contaminated soil.

[0025] Embodiment 2: As shown in the attached Figure 1 To Attachment Figure 3 As shown, based on the first embodiment, an irrigation box 2 is installed on the other side of the planting box 1;

[0026] A liquid storage tank 21 is provided at the bottom of the irrigation box 2, and a liquid inlet 211 is opened on the liquid storage tank 21. A liquid inlet pipe 23 is installed in the liquid storage tank 21, and the liquid inlet pipe 23 is connected to the pump body 22. The pump body 22 is connected to a liquid infusion pipe 24, and the liquid infusion pipe 24 is connected to a spray pipe 25. The spray pipe 25 is provided with a plurality of nozzles 251 for spray irrigation.

[0027] As can be seen from the above, the irrigation box 2 is used to irrigate the planted plants so that the plants can grow normally. During the irrigation process, the pump body 22 absorbs the irrigation liquid in the liquid storage tank 21 through the liquid inlet pipe 23, and transports it to the spray pipe 25 through the liquid delivery pipe 24. Each nozzle 251 in the spray pipe 25 corresponds to a planting hole 121, so that the irrigation liquid can be accurately sprayed on the plant through the nozzle 251 to avoid waste of irrigation liquid.

[0028] Embodiment 3: As shown in the attached Figure 1 To Attachment Figure 4 As shown, on the basis of the second embodiment, a shear box 3 is fixedly installed on one side of the planting box 1, and the shear box 3 includes a rotating rod 31, the rotating rod 31 is fixedly connected to a gear 1 32, the gear 1 32 is arranged inside the shear box 3, the gear 1 32 is meshed with a gear 2 33, a bidirectional threaded rod 1 34 is fixedly connected to the gear 1 32, the bidirectional threaded rod 1 34 passes through a moving block 1 36, a shear knife 1 361 is fixedly connected to the bottom of the moving block 1 36, a bidirectional threaded rod 2 35 is fixedly connected to the gear 2 33, the bidirectional threaded rod 2 35 passes through a moving block 2 37, and a shear knife 2 371 is fixedly connected to the bottom of the moving block 2 37;

[0029] A shearing layer 15 is arranged in the middle of the bottom mesh layer 14 , and a shearing knife 1 361 and a shearing knife 2 371 are arranged in the shearing layer 15 .

[0030] As can be seen from the above, the shear blade 1 361 and the shear blade 2 371 are double-edged blades. After the contaminated soil is repaired, the rotating rod 31 is rotated so that the rotating rod 31 drives the gear 1 32 to rotate. Through the meshing of the gear 1 32 and the gear 2 33, the gear 1 32 and the gear 2 33 respectively control the two-way threaded rod 1 34 and the two-way threaded rod 2 35 to rotate. When the two-way threaded rod 1 34 rotates, the two moving blocks 1 36 it passes through move toward each other in the shear box 3. When the two-way threaded rod 2 35 rotates, the two moving blocks 2 37 it passes through move in the opposite direction in the shear box 3, so that the shear blade 1 361 and the shear blade 2 371 can move toward each other to shear the plant roots between them.

[0031] Then, the rotating rod 31 is reversed to make the two moving blocks 2 37 on the two-way threaded rod 2 35 move toward each other, so that the shear knife 2 371 connected to the two moving blocks 2 37 shears the plant roots between them, so that the plant roots between the planting box 1 and the repair soil are completely cut, thereby separating the planting box 1 from the repair soil, making it easier to transfer the planting box 1 to other contaminated soils. By cutting the roots, the degree of damage to the plant roots can be reduced, and it can be avoided that the roots of the plants are pulled out and cause greater damage to the roots, resulting in breakage, tearing or damage to the roots, affecting the growth and vitality of the plants.

[0032] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
