摘要： A dredge supporting a pivotal ladder with a suction auger on its free end. A shroud assembly including front, center and rear sections surrounds a large portion of the periphery of the auger. The shroud assembly is pivotal about the axis of the auger and the front and rear sections are each independently pivotal relative to the center section so that the center section can be maintained at a relatively constant attitude independent of the inclination of the ladder and only a leading one of the front and rear sections, depending on the direction of movement of the dredge, is necessarily opened while the trailing section can remain closed adjacent to the auger. The articulation of the several shroud sections enables the suction auger head to operate in both directions with reduced turbidity and, therefore, increased efficiency.
