[0023] Working principle: When in use, the utility model discharges the required concrete into the lower hopper 2. When the concrete is discharged into the lower hopper 2, the reduction motor 10 is turned on by control. When the reduction motor 10 is turned on, it drives the first pulley 11 to rotate.
