Safe and environment-friendly ash discharging device for incinerator

The utility model relates to the technical field of incinerator appliances, in particular to a safe and environment-friendly ash discharging device for an incinerator. The pretreatment cavity is arranged, and the crushing rollers which rotate oppositely are arranged in the pretreatment cavity, so that fed waste can be pre-crushed, and subsequent incineration is facilitated; a rotatable V-shaped net plate is arranged in the incineration cavity, and waste falls on the net plate after entering the incineration cavity and is gathered at the low-lying position of the V shape; during incineration, the servo motor is controlled to drive the worm to rotate forwards and backwards, so that the worm gear drives the V-shaped screen plate to swing back and forth through the rotating shaft in a driven mode, waste products roll over, on one hand, incineration can be assisted, and on the other hand, ash can be decelerated to fall off from the screen plate and is discharged from the discharging pipe; and after incineration is
