A cleaner of root heads comprises a driving horizontal shaft with two base flat elastic cleaning elements tangentially fixed thereon, the free ends of which are connected with a shaft of the cleaner with the aid of flexible ligatures, and also additional cleaning elements are arranged diametrically opposite. The additional cleaning elements are made of elastic strips, the peripheries of which are fixed on a driving horizontal shaft and form spherical shapes in the cross-section, inside of which axles, fixed on the driving shaft, are disposed. At the ends thereof convex semispherical brackets are movably mounted, on the outer surfaces of the latters short resilient fingers, which come outside onto a convex cleaning surface through openings in the elastic strips, are fixed. In doing so on the axles between the driving shaft and movable brackets compression springs are mounted. |
