Abstract
A beach cleaner for recovering waste while traveling in a towed state by a traction vehicle. A grating-like portion scoops up waste present in front of the beach cleaner as the beach cleaner is moved. A rotor is disposed on an upper side of the grating-like portion and is adapted to rotate so that a lower portion thereof moves rearwardly. The rotor is mounted on a rotary shaft extending in the transverse direction of the beach cleaner. Waste is delivered rearwardly between the rotor and the grating-like portion. With travel of the beach cleaner, waste present in front of the beach cleaner is scooped up onto the grating-like portion and sand which is scooped up together with the waste is allowed to drop through gaps in the grating-like portion.
