Abstract
A device for collecting manganese nodules or the like from the ocean floor having a frame that is drawn across the ocean floor, a cylinder rotating around a horizontal axis which has on its circumference brushes for picking up manganese nodules in the circumferential direction. A screen surrounds the rear half of the cylinder. Hook-like rods mounted on the screen terminate in prongs pointing in the traction direction for digging out manganese nodules. The bristles can be made of bronze and are in the form of ribs running in the axial direction of the cylinder. Because of the brushes, the jamming of the nodules is prevented and at the same time a cleaning action is performed on the nodules.
