The invention relates to an environment-friendly device, in particular to an environment-friendly municipal
domestic waste centralized treatment device. The environment-friendly municipal
domestic waste centralized treatment device comprises a shell, a conveying base, a pushing box, a limiting plate, a belt I, a motor, a belt II, a
mashing box, a dry and wet separation box, a
grinding base, an electromagnetic box and a waste discharging limiting plate. The problems that an existing
waste treatment device is simple in structure and single in function, a general treatment method comprises the step that waste is collected to be buried or incinerated in a centralized mode, and a general
waste collection device does not have a
grinding function and the problem that in the
waste collection process, some waste can produce liquid, and the liquid can flow out to contaminate the environment can be solved. Conveying base springs, sliding bases, a small
bevel gear rotation shaft, a long key, a small
bevel gear, a small
bevel gear spring, a small bevel gear limiting plate, a small bevel gear shaft belt gear, a large bevel gear shaft, a large bevel gear shaft belt gear, a large bevel gear limiting plate, a large bevel gear, a small bevel gear belt and a conveying roller are arranged at the upper end of the conveying base.
