The applied 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 several cleaning elements, is mounted. The cleaning block consists of two hollow, elastic solid cones of different sizes, the vertices of which are arranged one to another and mounted on the shaft on a joint movable bush. The cone of a larger diameter is disposed in the front. The lower cone of a smaller diameter has reinforcement inside as rigid concentric rings mounted with gaps. The movable bush is additionally connected with the shaft with the aid of an extension spring. |
