Cultivated land soil remediation system

Abstract

The invention discloses a cultivated land soil remediation system. The cultivated land soil remediation system comprises a shell, wheels arranged at the bottom of the shell, a garbage collection box fixed to one side of the shell, a dustproof cover arranged on the shell, a feeding machine located on one side of the shell, a remediation chamber arranged in the shell and a primary screening chamberarranged in the shell. The remediation chamber comprises a third sieve plate, a plurality of second cams arranged at the bottom of one side of the third sieve plate, two first inclined plates locatedbelow the third sieve plate, a plurality of spray heads adjacent to the first inclined plates, a pump body connected with the spray heads, a spiral stirring shaft located below the inclined plates anda bottom plate located below the spiral stirring shaft; and according to the method, an in-situ remediation mode is adopted, the cultivated land soil is subjected to centralized treatment, the soil before cultivation is remediated through the processes of crushing, primary screening, refining, remediation liquid spraying and the like, the activity of the soil is restored, and compared with a traditional ploughing mode, the labor force is reduced, and the problem of heavy metal pollution removal is solved.

Description

technical field [0001] The invention belongs to the technical field of soil restoration, and in particular relates to a cultivated soil restoration system. Background technique [0002] Agricultural land refers to the land directly used for agricultural production, including cultivated land, forest land, grassland, etc. When the agricultural land is abandoned for a long time, the nutrients and components in the soil will be decomposed by microorganisms and lost, resulting in infertile soil. When the agricultural land is re-used, the soil of the agricultural land needs to be repaired. The traditional restoration requires soil restoration. Flipping, watering and fertilizing is a waste of manpower and time. For cultivated land, there are especially problems such as heavy metal pollution and soil compaction caused by the application of pesticides, which affect soil activity. In the existing technology, there are large-scale farming machines, which plow the land quickly, but the...

Problems solved by technology

When the agricultural land is abandoned for a long time, the nutrients and components in the soil will be decomposed by microorganisms and lost, resulting in infertile soil. When the agricultural land is re-used, the soil of the agricultural land needs to be repaired. The traditional restoration requires soil restoration. Flipping, watering and fertilizing is a waste of manpower and time. For cultivated land, there are especially problems such as heavy metal pollution and soil compaction caused by the application of pesticides, which affect soil activity.

In the existing technology, there are large-scale farming machines, which plow the land quickly, but the farming machines can only be used for loosening the soil and fertilizing, and have no function of removing pesticide residues. Removing pesticide residues requires later spraying or special reactions It is time-consuming and labor-intensive to remediate the soil with a kettle. Therefore, a soil remediation device for arable land is proposed
