Bonchyk V. Elaboration and substantiation of parameters of rotary potato digger.

The research presents scientific investigations concerning the increase of separating ability of a potato digger by designing of clod crushers installed at the beginning of tuber digging technological process. The constructive and technological parameters of the designed potato digger have been substantiated in the research. We present the theoretical dependences for definition of the constructive, cinematic and dynamic influences of a rotary work organ with vertical axle on the destroying process of a patoto bed. Main factors mostly influencing qualitative and energetic indexes of the mashine have been dertermined. The recommendations on choosing of rational working regime are worked out.
