Abstract

The high-quality implementation of the technological process of harvesting potatoes largely depends on the separation process. A separating elevator with cleaning rubber-coated blades is proposed in order to improve the process of separation of the soil-tuberous mass and reduce damage to tubers. The conveyor with rubber blades is located inside the main and moving against the direction of the separating elevator movement. Mounted blades with their touch will clean the lumens of the rods from sticking. The quality of the completeness of the separation of potato harvesters depends on the duration of the presence of the soil-tuberous mass on the working surface of the elevator. In the course of theoretical studies, the relative speed of movement of the soil-tuberous mass was analytically determined depending on the change in the mass of the soil layer after the interaction of the blades of the internal conveyor with the elevator bars. The range of change in the rational value of the elevator speed for elliptical shakers was taken into account. The graphs of the dependences of the relative speed of movement of the soil-tuberous mass on the kinematic parameters of the internal conveyor and on the congestion of the elevator are analyzed. It has been established that the interaction of the blades of the internal conveyor with the bars of the elevator has little effect on the speed of the soil layer. The internal conveyor with rubberized blades will clean the gaps between the bars of the elevator without resisting the movement of soil and tuber mass on the surface of the separating elevator, thereby improving the quality of soil separation and reducing damage to tubers.
