Further, the plant cultivation boxes 3 are evenly distributed around the first rotating shaft 8 in a circumferential manner.

The utility model discloses a theory of operation:

when the phytoremediation device for heavy metal contaminated soil is used, different types of plants are planted in the plant planting boxes 3, the plants of different types have different absorption capacities on heavy metals in the soil, for example, radish has weaker enrichment capacity on cadmium Cd, while cabbage has stronger enrichment capacity on cadmium Cd, so that different plant planting boxes 3 have different adsorption capacities on different types of metals in the metal contaminated soil below the plant planting boxes;

after the plants in each plant planting box 3 are planted, the plants grow for a period of time, at the moment, the root systems of the plants penetrate into the containing box 1 from the through holes 4 formed on the placing plates 2, the heavy metals in the heavy metal contaminated soil in the containing box 1 are absorbed, for example, when one of the plant planting boxes 3 plants Chinese cabbage, most of the heavy metal cadmium Cd in the soil below the Chinese cabbage is absorbed, so that the heavy metal cadmium Cd content is greatly reduced, the content of cadmium Cd heavy metal in soil at other positions is relatively high, then a motor 13 of a driving mechanism is started, the motor 13 drives a second rotating shaft 12 to rotate, the second rotating shaft 12 rotates to drive a driving gear 10 to rotate, the driving gear 10 rotates to drive a driven gear 11 to rotate, the driven gear 11 drives a first rotating shaft 8 to rotate, and the first rotating shaft 8 rotates to drive a plurality of plant planting boxes 3 connected with the first rotating shaft through a connecting rod 7 to rotate;

after the plurality of plant species plants case 3 and rotates, different plant species plants case 3 and just rotates different positions, for example: the method has the advantages that the plant planting box 3 for planting the Chinese cabbage rotates to other positions, cadmium Cd heavy metal in soil at other positions can be absorbed, if lettuce is planted in the original position plant planting box 3, most of lead Pb at the original position is absorbed due to the strong adsorption capacity of the lettuce on the lead Pb, and the lettuce absorbs the cadmium Cd heavy metal at the position, so that different plants can absorb different heavy metals in the same area, and the operation is simple and convenient;

when the position that some plants held the incasement 1 according to inserting is darker, when inconvenient rotation, starts pneumatic cylinder 5, and the hydraulic telescoping rod of pneumatic cylinder 5 promotes plate body 6 up-and-down motion, and plate body 6 up-and-down motion drives the left side of placing board 2 and slides along fixed slider 14 along spout 15, and the right of placing board 2 simultaneously slides along the logical groove of seting up on holding case 1 along fixed plate body.

To sum up, the utility model provides an adopt different plants to carry out the plant prosthetic devices of absorptive heavy metal contaminated soil to different microelement in the soil in same region, through the plant to heavy metal absorption, volatilize, root filter, degradation, effect such as stable, reach the effect of pollutant in purification soil and the water body, realize utilizing multiple plant to absorb the heavy metal of different types in the soil, finally make heavy metal contaminated soil obtain restoreing.

The above disclosure is only for a few specific embodiments of the present invention, however, the present invention is not limited to the embodiments, and any changes that can be considered by those skilled in the art shall fall within the protection scope of the present invention.
