At this time, the baffle 5 at one end of the material box 42 toward the hopper 1 rotates to open the bottom of the material box 42, so that the raw materials of the required weight fall from the material box 42 into the hopper 1, and at the same time, the baffle 5 at one end of the material box 42 away from the hopper 1 rotates to close the top of the material box 42, and at the same time, the conveying of the raw material conveying pipeline is stopped to avoid excessive mixing of raw materials resulting in an imbalance in the proportion of the raw materials. The raw materials entering the hopper 1 are stirred. The mixing blades 16 are rotated to stir and mix the raw materials. After the raw materials are stirred and mixed into concrete, the opening 17 is opened to discharge the concrete into the sleeper mold box 22 for casting the sleeper. The concrete is cast in sequence in all the sleeper mold boxes 22 arranged along the length direction of the guide rail 24 through the conveying frame of the conveyor vehicle 25, and the casting of the sleeper is completed; after the sleeper is solidified and fixed, the sleeper mold box 22 is driven by the driving vehicle 27 to slide toward the end of the length direction of the placement frame 26, and the sleeper mold box 22 swings when passing through the vibrating gear ring 31 to loosen the sleeper.
