Substantiation of the construction and technological scheme of the underground separatory working body of the potato harvesting machine

Goal. To improve the quality of potato harvester by substantiating parameters and improving design digging separating working body. Methods. Analytical — during analysis structures technological processes bodies harvesters. Mathematical for determining bodies. Results. It is determined that it possible to increase indicators harvesters increasing efficiency process separation soil impurities on The construction-technological scheme digging-separating body with device uniform distribution dug-up heap width a cloth rod-elevator conveyor are substantiated. Conclusions. Laboratory field studies digger KRK-2 loader KKN-2 new (parameters: drum diameter D=560 mm; height bar H=250 alignment between drums A=350 rod dr=18 circular speed rotation VD=2.8 m/s; number rods k=20, length distributor wing l=450 mm, h=150 angle α=40–45°, gap Δ=80 distance L=600 mm), showed proposed improves
