Abstract
The article presents the design of a rod elevator with an adjustable inclination angle of the apron, which reduces damage to marketable products of root crops and bulbs with maximum separation. The results of theoretical studies of a rod elevator on substantiation of the structural and technological parameters during its interaction with a heap of onion sets are presented. The constructive-technological scheme of the separating rod elevator with an adjustable inclination angle of the apron which improves the quality indicators of harvesting onion sets is substantiated and developed. It has been established that with increasing angle of the longitudinal inclination of the apron, the relative speed of movement of the heap of onion sets decreases. In the absence of air flow, the relative velocity of the onion set heap with a longitudinal change in the inclination of the rod elevator apron in the considered range varies from 0.34 to 0.47 m / s. Changing the angle of the longitudinal inclination of the rod elevator by 5º significantly changes the relative average speed of movement of the heap of onion sets. A mathematical model of the movement of a heap of onion sets along the surface of the rod elevator with a change in the direction of its oscillations in the horizontal plane is developed
