The sweeping unit includes a scraper (31) and a cambered notched rod (40) carrying the sweeping unit. A toothed wheel (21) of the drive system engages with the rod for requiring reciprocating movement of the rod. A fixed cambered guide (50) slides relative to the rod, and guides the movement of the rod. The rod extends from a distal end toward a proximal end secured to the sweeping unit.</p> |
