A cleaner of root heads from top residues has a frame with a console driving shaft, mounted in the longitudinal-vertical plane as inclined one, at the end of which a cleaning block, which consists of cleaning elements as elastic disks, is arranged. The cleaning block is formed by two elastic disks of the same diameter and of the same rigidity, which have a gap therebetween, in which resilient thin plates of an arched shape, connecting the peripheries of the disks therebetween, are mounted. Said plates are arranged with a corresponding space to each other and are guided in the direction from the axle of the shaft by raised parts thereof. One of the disks is mounted on the shaft movably with the aid of a mechanism of changing and fixing the gap between the disks. |
