The invention relates to agricultural machine building, in particular to working tools of potato harvesters. A cleaner is made in the form of upper and lower hollow cones directed by vertexes to each other, is connected to a rotary actuator. The lower hollow cone of the cleaner has in the center a hollow protrusion of conical form directed inside thereof, which is formed by round rods installed concentrically and with a gap to each other, which together with the lower hollow cone of the cleaner form two unloading sleeves of cylindrical form, which are located with a gap to each other round transverse rods. Above the hollow protrusion a two-blade beater is located with a gap, it is installed on the end of a cantilever drive shaft located below. Under the lower part of the cleaner a shaped root guide is located. The new design of apparatus allows to increase quality of cleaning tuberous roots from impurities by 25...30 %. |
