The invention discloses an automatic discharging machine, relates to the field of plastic processing machinery, and solves the problems that an existing discharging machine is low in working efficiency and easy to bridge. The machine comprises a storage cylinder, a rotating plate, a stirring paddle, a motor, a transmission device, a longitudinal propelling device, a discharging opening and an extruding machine, wherein the material storage cylinder is arranged above the extruding machine, the discharging opening is formed in the bottom of the material storage cylinder, the rotating plate is arranged inside the storage cylinder, the stirring paddle is connected with the rotating plate, the longitudinal propelling device is arranged on the outer wall of the discharging opening, and the motoris respectively connected with the rotating plate and the longitudinal propelling device through the transmission device; the automatic discharging machine is used for stirring at the upper part of the discharging opening by adopting the stirring device, so that the phenomenon of bridging is prevented; and the bottom carries out propelling on the side wall by adopting the longitudinal propellingdevice, so that the direct propulsion mode of the traditional feeding equipment is changed, and the feeding speed is increased.
