Problems solved by technology
[0003] When planting plants to restore soil on soil polluted by heavy metals, most of the existing seed sowing methods are to first shovel out the grooves in the soil using manual or shoveling machines, then use manual or seeding machines to sow, and finally cover the soil. , if manual slotting, seeding, and soil covering are used, and if slotting machines, seeders, and soil covering machines are used for work, a variety of different machines are required to perform slotting, seeding, and soil covering in sequence, which makes the work efficiency extremely low and the cost It is extremely inconvenient to use different machines, requiring multiple people to operate, which greatly wastes labor resources

Embodiment Construction
[0028] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0029] Such as Figure 1-Figure 5 Shown, the using method of a kind of heavy metal contaminated soil remediation device of the present invention, comprises the following steps:
[0030] S1. Select different plant seeds according to the heavy metal components contained in the heavy metal-contaminated soil. The corresponding relationship between plant seeds and heavy metal elements is as follows: Lishihe corresponds to Cr, Sedum sedum corresponds to Zn, Centipede grass and Daye Jingkou sidegrass Corresponding to As, pokeweed corresponding to Mn, Baoshan Dongcai corresponding to Cd, Huping broken rice shepherd corresponding to Se, anthiaceae corresponding to Zn and Cd, vetiver corresponding to Zn, shepherd's purse corresponding to Pb, Cd and Zn and o...

The invention relates to the technical field of remediation of heavy metal-contaminated soil, and specifically relates to a method for using a device for remediating heavy metal-contaminated soil. The remediation device for heavy metal-contaminated soil adopted in the method includes a drive mechanism, a soil-covering support mechanism, a shovel mechanism and a seeding mechanism. The earth-covering supporting mechanism is arranged on one side of the driving mechanism, the soil-shoveling mechanism and the seeding mechanism are both arranged inside the earth-covering supporting mechanism, and the earth-shoveling mechanism is arranged below the seeding mechanism, and the driving mechanism is composed of a box body , a fixed frame, a two-axis servo motor, a coupling, a rotating shaft, a first transmission wheel, a driven shaft, a second transmission wheel, a transmission belt and a drive wheel. By inserting the set limit bolts into the through holes of different heights, the ground clearance height of the covering roller can be adjusted, and the expansion and contraction of the telescopic end of the cylinder can drive the angle of the shovel to adjust, which is convenient for adjusting the shovel. Topsoil at different depths.
Description
technical field [0001] The invention relates to the technical field of heavy metal-contaminated soil remediation, in particular to a method for using a heavy metal-contaminated soil remediation device. Background technique [0002] Heavy metals refer to metals with a specific gravity equal to or greater than 5.0, such as Fe, Mn, Zn, Cd, Hg, Ni, Co, etc. Soil heavy metal pollution refers to the excessive deposition of trace metal elements in the soil due to human activities, which is collectively referred to as soil heavy metal pollution. Soil heavy metals refer to the phenomenon that human activities add metals to the soil, causing the heavy metals in the soil to be significantly higher than the original content, and resulting in the deterioration of the quality of the ecological environment. The remediation of heavy metal-contaminated soil can be divided into two types in terms of treatment strategies: one is stabilization, which stabilizes heavy metals in the soil to limi...
