[0002] The soil pollution treatment screening device of existing screening device cannot effectively crush the blocky soil, leading to that it cannot fully separate the gravel in the soil, and cannot effectively remove the iron or other metal substances in the soil, affecting the overall quality of soil treatment.

[0003] In the patent with the publication number CN213854709U, a soil pollution treatment screening device is provided. In the patent, the soil to be screened is introduced into the screening net through the feed inlet during daily use. The connecting rod and the pressure plate are driven by the swing motor to reciprocate, so that the crushing teeth can pound and crush the soil on the screening net. At the same time, the screening net vibrates during the pounding process due to the contraction and reset of the buffer spring, so that the crushed soil on the screening net can be vibrated and shaken off to achieve screening, which improves the overall efficiency of screening and greatly reduces the overall cost of screening. During daily use, the magnet roller is driven by the transmission motor to rotate in real time, and the iron and other metal substances in the crushed and falling soil are adsorbed and removed.
