AI Technical Summary
Technical Problem
Existing technologies lack the function of automatically turning over the topsoil, requiring manual turning of the soil periodically, which leads to high labor intensity and low efficiency.
Method used
The system uses a drive mechanism and an adjustable-height soil-turning mechanism to automatically and efficiently turn the soil on the surface of contaminated soil using a soil-turning rake. It also utilizes the negative phototaxis of the light source to prevent earthworms from being injured, and a spraying mechanism is set up to maintain soil moisture.
Benefits of technology
It has achieved automated soil turning, reduced manual labor intensity, improved soil turning efficiency, protected earthworms, ensured soil aeration and moisture, and prevented soil compaction.

Abstract
The utility model relates to the technical field of soil remediation, and discloses a device for improving soil heavy metal by earthworms, which comprises a remediation bed, the top of the remediation bed is fixedly connected with a portal frame, a driving mechanism is arranged at a position close to the top in the portal frame, and a support frame is arranged at the bottom of the driving mechanism. A soil turning mechanism with the adjustable height is arranged on the supporting frame, and light sources are fixedly installed on the top of the inner wall of the portal frame and located on the two sides of the driving mechanism. Through cooperative use of the driving mechanism and the soil turning mechanism with the adjustable height, a soil turning harrow in the soil turning mechanism can be driven to repeatedly, automatically and efficiently turn soil on the surface layer of a polluted soil mixing layer, soil on the surface layer of the polluted soil mixing layer is prevented from being hardened, the air permeability of the soil is guaranteed, and the soil turning efficiency is improved. In addition, transmission manual soil turning operation is replaced, the labor intensity of workers is relieved, and time and labor are saved.
