It is disclosed a beach sand-cleaning method and mechanism characterised by two distinguished processes. According to the first process the sand is stirred by the rotor 2 (fig.1) rotating at constant velocity while the mechanism is moving on the surface subjected to cleaning; throughout stirring, rubbish is lunched on the conveyor 5 along with a little quantity of stirred sand and then conducted to screens where the sand is released and the rubbish conducted to the trash can provided. Accordingto the second process, the main quantity of the stirred clean sand moves between the wedge-like part 1 and the conveyor 12 before falling on the ground. The advantage of the invention is that the mechanism in question is an energy-saving mechanism susceptible to improve the productivity of the sand-cleaning machines. |
