There is a rotating shaft at the bottom of the swinging nozzle, and an iron outlet is provided on each side. There are two rows of empty iron tanks below the iron outlet. When the swinging nozzle tilts to the left around the bottom rotating shaft, the iron tank on the left is filled with iron; after it is full, the swinging nozzle tilts to the right around the bottom rotating shaft, and the iron tank on the right is filled with iron, and then the left iron tank is operated to move forward one tank, so that the left and right sides are circulated, and the iron tapping task is completed after filling two rows of iron tanks.
