Abstract
Due to the lack of theoretical studies of modelling potato separation on the rod elevator, the authors conducted research of potato separation completeness on the elevator of potato harvester type KPK-3. The research resulted in designing a mathematical model of separating potato impurities on the potato harvester elevator that can help determine the completeness of separation on the elevator. As a result, the authors derived equations of the distribution of separating fineness over the elevator apron length; proved equations of connection between the elevator length and separating fineness. It was established that separation fineness depends functionally on the length of the elevator apron section and two coefficients, each of which can be determined according to the experimental data of separation fineness at two sections of the elevator’s operating flight. It is established that when using the KPK-3 type potato harvester, 90% separation is reached when increasing the length of the rod elevator to 1800 mm with a given proportion of separated impurities of 50% at the length of 600 mm and 75% at the length of 1000 mm.
