Crushing device for heavy metal contaminated soil treatment

The utility model relates to the technical field of soil remediation, in particular to a crushing device for treating heavy metal contaminated soil. According to the crushing device for heavy metal contaminated soil treatment, soil to be crushed is crushed multiple times through the arranged crushing bin, and therefore the problems that a traditional crushing device cannot fully crush the soil, and crushing dead corners exist are solved; meanwhile, the screening bin arranged at the lower end of the crushing bin is suitable for further particle size screening of the crushed soil, so that some hard soil blocks which cannot be crushed and impurities carried in the soil are screened out, the problem that the crushed soil needs to be manually screened is avoided, and the repairing efficiency after the soil is crushed is improved; and through reasonable arrangement of the structures of the crushing bin and the screening bin, the crushing efficiency is greatly improved, and the technical problem that a traditional c
