FIELD: agriculture.SUBSTANCE: suggested cutter for growing soybean stripping contains floating platform with outside dividers, unloading device with fan, front and rear along movement direction drums with stripping combs with teeth 9 and holes 10 at places of their side edges connection in base of the tooth 9 covered by enclosures. Side edges of the tooth 9 of the stripping comb are made according to hypocycloid:where: R is radius of guide circle; r is radius of generating circle; ? is angle of rotation of the generating circle. At that the hypocycloid is plotted at ratio R=3r, two branches 14 start from top of tooth 9 and crosses axis x of the guide circle in places of their connection Edge of the hole 10 at place of connection of side edges 11 in the base of tooth 9 has groove.EFFECT: improved space filling between teeth of the stripping comb, and trajectory of soybean grains movement, reduced weight of the stripping comb.3 cl, 4 dwg |
