A cleaner of tuberous root heads consists of a vertical driving shaft, on which cantilever elastic blades are arranged radially by means of double-arm levers, kinematically connected to a slider, as well as of links and hinges. The driving shaft is disposed outside of an immovable hollow axle, inside which an additional driving shaft is disposed with a gear wheel fixed at the end thereof. Said wheel engages with the gear wheels of additional cleaning blades which have larger rigidity than the cantilever elastic blades. The axles of the additional cleaning blades are mounted in cantilever fashion to the immovable toothed wheel fixed at the end of the hollow axle. The cantilever elastic blades are also made as rotary ones and have fixed gear wheels engaging with immovable toothed wheel of the hollow axle and have the directions of rotational movements which are opposite to the moving directions of the additional cleaning blades. |
