SWEEPER WITH MAIN BRUSH DRIVEN BY MECHANICAL TRANSMISSION AUTHORIZING BRUSH ADJUSTMENT

摘要

The present invention relates to a sweeper intended to be moved on the ground (S) to function, comprising a single main wheel (210) for driving a brush (420) with a horizontal axis, when the sweeper rests on a floor flat, a dust collection tank (430), said brush being intended to send the dust into the collection tank (430). According to the invention, the brush (420) is connected, via a mechanical transmission (T), to a shaft (212) integral with said wheel, said mechanical transmission comprising means (470, 470 ') providing a freedom of movement of the axis of the brush (420) in two directions (x, y), to lower it, to raise it, in order to compensate for its wear and / or to advance it, to move it back towards screw a free edge of a front wall (432) to maintain its effectiveness. The sweeper of the invention, equipped with a mechanical transmission between its main wheel and its brush, provides the same efficiency as a sweeper with hydraulic transmission. Its manufacturing cost is notoriously lowered.
