Abstract:
A sweeping machine comprising:two driven circular brooms which can be rotated in opposite directions with respect to each other, and a sweeping plate over which the driven circular brooms sweep, said sweeping plate provided with an elastic sweeping lip which, in an operational state of the sweeping machine, is positioned at least partially flush with the ground, wherein, starting from its in use ground-sided contact area, the sweeping lip is designed so as to be increasingly flexible in a direction of an upper-sided sweeping area so that, when the sweeping lip encounters an impediment, a front face area of the sweeping lip performs an automatic elastic avoidance movement in the upward direction, and wherein the increasingly flexible design is achieved with at least one of a material weakening structure in the upper-sided sweeping area and a reinforcement insert in the ground-sided contact area.
