[0002] Soil remediation refers to the technical measures of transferring, absorbing, degrading and transforming pollutants in the soil by physical, chemical and biological methods to reduce their concentration to an acceptable level, or converting toxic and harmful pollutants into harmless substances. It can be roughly divided into three methods: physical, chemical and biological.

[0003] For example, CN220111187U discloses a soil screening device for soil remediation, which can continuously lift the filter plate upward to vibrate when screening the soil, and can reduce the clogging of the filter plate under the force, and at the same time can also improve the effect and efficiency of soil screening under the force, thereby improving the practicality of the screening device and facilitating the screening work. However, the soil to be screened often has a certain humidity, and even if the filter plate can be continuously vibrated, the wet and agglomerated soil will still be filtered above the screen, thereby affecting the screening effect of the soil.
