The utility model provides an automatic change forest peeling apparatus, relates to the forestry engineering field, and including base, quick -witted case and two stripping roller, quick -witted case is installed on the base, and stripping roller sets up at quick -witted incasement, stripping roller's below be provided with the bark reducing mechanism, the below of bark reducing mechanism is provided with the screw extruder, the discharge gate setting of screw extruder is at its tip. The utility model discloses add the bark processing capacity on the existing equipment basis, the bark that produces in the time of can skinning to timber is in time handled to direct bagging -off is deposited, thereby makes production site cleaner and tidier. The utility model discloses a bark reducing mechanism and screw extruder are handled the bark, the bark of output through smashing with pressing process after, the space that occupies significantly reduces, simultaneously, the bark smash saw -dust that the back formed can be directly as saw -dust processing product's raw materials, and need not to handle once more to the recycle of bark is more convenient for.
