The invention discloses a recovery processing device of waste dry batteries. The recovery processing device comprises a supporting frame, a detachment box, a feed hopper, a material pouring device, a rotating table, a sleeve, a lifting shaft inserted in the sleeve and capable of moving up and down relative to the sleeve, an installation rod, a motor, a rotating shaft, a cylindrical cam arranged on the rotating shaft and capable of synchronously rotating together with the rotating shaft, a first gear and a second gear. A rolling piece is arranged in a curve groove of the cylindrical cam and connected with the lifting shaft through a connection rod. A first through hole, a second through hole, a third through hole and a fourth through hole are formed in the rotating table. An impact rod is connected to the installation rod. A push-out rod is connected to the installation rod. A fifth through hole and a sixth through hole are formed in the detachment box. A first collection box and a second collection box are arranged on the supporting frame. Shells and inner cores of waste dry batteries can be effectively recovered in a separated mode, and meanwhile the labor intensity of operation workers is remarkably lowered.
