Technical Field

[0001] The utility model relates to the technical field of soil screening devices, in particular to a soil screening device for soil remediation. Background Art

[0002] With the acceleration of industrial development, agricultural activities and urbanization, soil pollution is becoming increasingly serious. Industrial waste discharge, excessive use of pesticides and fertilizers, sewage irrigation, and oil spills have caused excessive levels of heavy metals, organic matter, and other harmful substances in the soil. In order to protect the ecological environment and human health, soil remediation has become an important task in the current environmental field. Restoring contaminated soil can restore its ecological functions, ensure the safety of agricultural products, and promote sustainable development.

[0003] In the soil remediation process, soil screening is an important pretreatment step. Various impurities and foreign matter often exist in the soil, such as stones, bricks and plastic fragments. These impurities will affect the implementation and remediation effect of subsequent remediation processes. For example, when using chemical remediation methods, impurities may hinder the full contact between the remediation agent and the soil. In the biological remediation process, impurities may have a negative impact on the growth and activity of microorganisms. These impurities and foreign matter can be removed through screening devices, making the soil texture more uniform, which is conducive to subsequent remediation operations.

[0004] Traditional manual screening involves using a screen to shake or stir the soil. This method is extremely inefficient and time-consuming, especially for large quantities of soil requiring remediation. Furthermore, manual screening accuracy and uniformity are difficult to guarantee, and screening results can vary significantly between operators, leading to inconsistent soil treatment quality.
