The invention discloses a stacking machine capable of being stably operated to realize rapid transportation. The stacking machine comprises a hoisting mechanism and a stacking disc matched with the hoisting mechanism, wherein the hoisting mechanism comprises a movable hanging frame, a hoisting mechanism and a driving mechanism which is arranged on a movable hanging frame transverse beam to drive the hoisting mechanism to move leftward and rightward; the driving mechanism is provided with four first hoisting wheels which are connected with second hoisting wheels arranged at four corners of the upper end face of a hoisting bottom frame of the hoisting mechanism; rotary locking mechanisms are arranged at left and right ends of the upper end face of the hoisting bottom frame along an edge of the hoisting bottom frame; the stacking disc is provided with a locking part for fixing the rotary locking mechanisms; the rotary locking mechanisms are controlled to rotate through retraction of a retraction device and then are tightly locked with or separated from the locking part. The stacking machine provided by the invention has a simple structure and the stacking disc is firmly fixed; the stress on the hoisting mechanism is uniform, and the hoisting mechanism is horizontally hoisted; the stacking machine is stable and does not swing in a transportation process; when the stacking disc is placed, the whole stacking is ordered, an occupied space is reduced and the stacking is safer; the working efficiency is greatly improved.
