The invention relates to the technical field of material unpacking equipment, and particularly discloses ratchet chain type automatic bag breaking equipment which comprises a base and a bag breaking bin. The bag breaking bin comprises a feeding opening and a waste bag discharging opening, the bag breaking bin is internally provided with a bag breaking mechanism close to the feeding opening, a waste bag extruding mechanism close to the waste bag discharging opening and a chain wheel mechanism penetrating through the feeding opening and the waste bag discharging opening, and the chain wheel mechanism is used for receiving material bags input from the feeding opening and conveying the material bags to the waste bag discharging opening; the bag breaking mechanism is used for cutting the material bags conveyed by the chain wheel mechanism, so that the material bags are unloaded; the waste bag extruding mechanism is used for smoothly discharging and recovering the empty material bags after unloading, rapid bag breaking of the material bags is achieved, the material bags are prevented from being blocked in the bag breaking bin, materials are smoothly discharged, blocking of the discharging opening due to winding of the waste material bags is effectively avoided, the outer side of the discharging opening can be sleeved with a waste bag collecting bag, and the waste bags are recycled ina centralized mode.

The invention discloses a combined roller bag breaking device for household garbage in bags. The bag breaking device belongs to the field of environment protection equipment and comprises a draught fan assembly, an inner roller, an outer rolling ring and a base assembly. The inner roller is sleeved with the outer rolling ring. The inner roller and the outer rolling ring are each supported by a rolling wheel supporting mechanism on the base assembly. The outer rolling ring is provided with bag breaking nails, and the bag breaking nails are inserted in kidney-shaped holes in the inner roller. The draught fan assembly is arranged at the end, with the inclined face higher, of the base assembly. The wind direction of an axial flow draught fan directly faces the upper side face of the inner wall of the inner roller. When the household garbage in bags is placed therein through the high end of the inner roller, a speed reduction motor drives the inner roller to rotate; the bag breaking nails drive the outer rolling ring to rotate; and meanwhile, the bag breaking nails are inserted into and pulled out of the kidney-shaped holes in a reciprocating manner, so that the garbage bags are punctured, under the wind action of the axial flow draught fan, the garbage bags fall off the bag breaking nails, and garbage is collected through a special collection box. By means of the combined roller bag breaking device, the bag breaking effect is enhanced; bag breaking efficiency is improved; and the combined roller bag breaking device is simple in structure and great in practicability.
