It mainly includes residents' domestic waste, market trade and commercial waste, public place waste, street sweeping waste and waste from enterprises and institutions. When domestic waste needs to be screened, a drum screening machine is used. Since the drum of the existing screening machine rotates for a long time and is in direct contact with the garbage, dirt is easily retained on the inner side. If it is not cleaned in time, the dirt will agglomerate, resulting in blockage at the drum mesh opening and the screened garbage needs to be transported with a conveyor belt, which is time-consuming and labor-intensive. For this reason, a reciprocating screening device for domestic waste is proposed. Utility Model Content
