The
increase
of the efficiency and quality of
performance of the work process of potato
heap separation can be achieved by means of improving the design of the vibrational spiral
separator and substantiating theoretically its rational parameters under the condition of
eliminating damage to the potato
tubers. An equivalent schematic model of the interaction
between the potato tuber and the surface of the cantilever spiral springs has been devised. On the
basis of the model, the kinematic characteristics of the tuber’s flight and its impact contact with
the elastic surface of the over
mounted rebounding conveyor have been investigated. A new
analytical mathematical model of the potato tuber’s flight from the surface of the spiral
separator
and its subsequent encounter with the
rebounding conveyor mounted above the spiral springs has
been developed. New analytical dependences have been obtained for finding out the distance and
height of the potato tuber’s flight to the point of impact contact as well as the trajectory equation
fo
r the travel to the said contact, which makes it possible to obtain the kinematic constraints
imposed on the allowed rate of travel under
the condition of not damaging the tuber. On the basis
of the obtained analytical dependences, the kinematic parameters
of the improved design of the
spiral potato harvester separator in its interaction with a
potato tuber under
the condition of not
damaging the latter have been investigated
