The present invention installs a placement box into a connecting groove by setting a feeding mechanism and a connecting mechanism, and at this time, a docking block is inserted into the docking groove, so that a first rotating block and a second rotating block complete docking. When multiple placement boxes are installed, the rotating column drives a push plate to move, and the push plate displacement pushes the plug block to move out of the slot, and the baffle rotates, and the raw materials fall into the mixing barrel, so that while the stirring motor drives the stirring shaft to rotate to stir the internal materials, the next material can be proportioned, and the materials can be placed in the placement box. When the concrete is discharged from the stirring shaft, the proportioned materials can be directly poured into the mixing barrel for mixing, which is convenient for adding materials and improves the production efficiency of concrete.
