Description

Technical Field

[0001] The present invention relates to the technical field of land improvement, and particularly relates to an ecological restoration device for comprehensive land improvement. Background Art

[0002] Under the rapid development of modern industrial society, the unreasonable exploitation of mineral resources and their smelting emissions, long-term sewage irrigation and sludge application to the soil, atmospheric deposition caused by human activities, application of chemical fertilizers and pesticides, etc. have all caused serious pollution to the soil, especially in industrialized cities. In land restoration, phytoremediation is a restoration method with low cost, no change in soil properties, and no secondary pollution. For land with relatively low pollution, phytoremediation can be used to treat soil organic pollution. However, for soil with relatively serious pollution, it is necessary to first conduct preliminary restoration of the soil through chemical leaching, and then conduct phytoremediation on the leached soil. During the restoration process, since the soil contains stones, the soil is prone to hardening and wrapping around the stones, resulting in insufficient internal leaching of the soil, and the stones will also affect the subsequent restoration operation of the soil; at the same time, the soil also contains some plastic wastes that are difficult to degrade, such as garbage bags.

[0003] Currently, when repairing land, turning the soil, spraying the restoration liquid, crushing stones, and cleaning garbage are all carried out by manual labor in cooperation with auxiliary tools. The efficiency of manual soil turning, stone crushing, and garbage cleaning is low and the labor intensity is high, reducing the efficiency of soil restoration; and during the process of manual soil turning, it is impossible to spray the restoration liquid on the soil synchronously, making it difficult for the subsequently manually sprayed restoration liquid to uniformly penetrate into the soil, resulting in poor soil restoration effect and affecting the subsequent use of the soil. Summary of the Invention

[0015] 2. Through the cooperation of the soil loosening drill bit and the soil loosening teeth in the soil loosening mechanism, the topsoil layer can be effectively loosened and the hardened soil can be initially broken up.
