Discharging device with waste residue centralized recycling function

The utility model discloses a discharging device with a waste residue centralized recovery function, which comprises a base body butted at the output end of external feeding equipment, and further comprises a guide groove formed at the inner end of the base body, a connecting shaft is nested and butted at the inner end of the guide groove, a first spring is butted between the connecting shaft and the guide groove, and a second spring is arranged at the outer end of the guide groove. Meanwhile, the outer side of the connecting shaft is nested and butted with a filter screen layer; and the first traction rope is in butt joint with the inner side of the base body and is in butt joint with the interior of the filter screen layer. According to the discharging device with the waste residue centralized recycling function, as impurities separated from the surfaces of the two filter screen layers are accumulated to a certain weight, the filter screen layers which are stressed to move downwards are matched with tractio
