Battery material recovery device

The invention relates to a battery material recovery device, which comprises a material receiving mechanism used for obtaining a to-be-recovered battery; the crushing mechanism is used for crushing the to-be-recycled battery to obtain a battery material; the sorting mechanism is used for sorting the battery materials to obtain different types of battery materials; the discharging mechanism is used for collecting the sorted battery materials, the material receiving mechanism, the crushing mechanism, the sorting mechanism and the discharging mechanism are arranged from top to bottom, the discharging mechanism comprises a plurality of material collecting boxes, the tops of the material collecting boxes communicate with a negative pressure exhaust pipeline, and the negative pressure exhaust pipeline communicates with the discharging mechanism. The negative-pressure exhaust pipeline is used for forming a negative-pressure environment in the negative-pressure exhaust pipeline so as to discharge dust and promote bla
