| 摘要 |
The present invention relates to a machine which makes it possible to clean sandy beaches in depth, and to mechanically remove waste exceeding a given size. The machine consists of a chassis (3) on wheels (4) on which a sieve tube (1), rotating on itself, is centred. The sieve tube (1) is an endless screw (6) fixed inside a screening cylinder (7). The shape of the continuous spiral blades (6) and the rotation of the tube make it possible to dig up the sand, which rises in the screening part of the tube (7), passes through the mesh of the sieve and falls back onto the beach. The coarse elements rise along the spiral as far as the upper part of the tube where they are recovered in a bucket (11) attached to the machine. The machine is drawn by an independent vehicle (12) which provides the energy necessary for rotating the tube (1). <IMAGE>
