Design mathematical model of the movement of heap particles during vibration cleaning of potatoes from impurities

Goal. To substantiate rational constructive and kinematic parameters of the V-shaped distributor potato heap offered design combined digging separating working body harvester. Methods. Theoretical research was conducted using basic principles higher mathematics theoretical mechanics. Numerical calculations graphical dependencies are obtained a PC based on developed standard programs. Results. The movement wing surface in process its distribution over entire width conveyor studied. An equivalent scheme interaction particle with is constructed, which differential equations motion specified made, take into account main structural V-like distributor. Based integration this system quadratures, analytical expressions that describe laws change velocity displacement particles time at different values conveyor. expressions, were performed dependences along angle wings taking oscillations blade obtained. Conclusions. allowable speed determined, provided equality supply to ascent from maintained. 1.62 m·s–1. Analysis relationships shows decreases increasing inclination wing. If reduced less than value, will be unloaded distributor, lead violation technological With wing, maximum deflection range 40–45°.
