The steering portion includes a support bearing structure mounted at the outlet opening to be swung about a vertical axis designed to have two parallel side plates between which a steering nozzle is pivotally mounted about a horizontal axis. Below the steering nozzle, designed to have a rectangular cross section and between the two side plates, a reversing bucket is pivotally mounted. This reversing bucket is link connected to the steering nozzle so that when the fore end of the steering nozzle is swung upwards, it will swing from a position up under the steering nozzle to a downwardly swung position.
