A root head cleaner differs from the known technical solutions in that additional cleaning elements are made as movable brackets, having a U-shaped profile in the transverse plane, with the bases directed to a driving horizontal shaft, and in the longitudinal plane - a shape of a right-angled triangle, with the vertex directed in the rotational direction, mounted into the guides arranged on the generating surface of the shaft. The rear parts of the brackets are additionally connected with the shaft by compression springs. In doing so from above on the brackets four camshafts, which are mounted into arched openings of the side parts of the brackets and connected therewith by torsional springs, are arranged in series. |
