This invention provides a self-feeding progressive brick-making device for construction waste, belonging to the field of brick making. It includes a lower frame, with an upper frame fixed above it. The lower frame holds a brick mold to be pressed, and the construction waste to be pressed is placed inside the brick mold. An upper mold, corresponding to the brick mold, is mounted above the brick mold and can press the material downwards. The upper frame is fitted with a lead screw that rotates up and down via a self-rotating axis through a vertical threaded hole. A ring-shaped cam is coaxially fixed to the lower part of the lead screw. Two or more ring-shaped, evenly distributed pressing heads are located below the cam. The upper part of each pressing head elastically presses against the pressing surface below the ring-shaped cam. This device continuously vibrates while pressing the construction waste inside the brick mold using the upper mold, ensuring uniform distribution of the waste material and improving the quality of bricks made from construction waste. Furthermore, the device has a simple and compact structure, significantly reducing the overall size of the device.
