Abstract

The need to develop specialized machines and equipment for laboratory and field research on potato breeding is due to the fact that the methodology of breeding processes and the first stages of seed production involves comparing many plants of different origins and selecting the best for further work up to the creation of a new variety or transfer of seeds for propagation in production conditions. The large variability of machines for unloading vegetables and potatoes does not adequately prevent damage to vegetable and potato products, which is due to the imperfect design of such machines, including the imperfection or absence of patterns of automated control of the technological process of work and justification of the parameters of their working parts. The purpose of the study is to substantiate the parameters of the conveyor for unloading vegetable crops and potatoes into storage and to determine the patterns of formation of the control signal of the transfer function of automatic control of operation. The power required to move the pick-up depends on the maximum pressure force of introducing the intake element into the embankment, the mass of the pick-up and the rolling resistance coefficients of the running wheels of the pick-up and transport sections. The length of the unloading conveyor of the machine is determined by the reserve zone to prevent wheels from hitting the tubers, their maximum difference in the embankment, the height of the layer, as well as the angle of inclination of the unloading conveyor. The width of the conveyor belt for unloading products from storage is determined by the values of the coefficient of friction of root crops on the surface of the belt, the coefficient of working time utilization and the forward speed of the conveyor belt. After removing the collapsed mass of tubers, the line of crumbling slopes and the limiting equilibrium are a straight line, characterized by an empirical equation for determining the coordinates of the tuber collapse point, the height of the tuber layer and the embankment collapse coefficient. When the feeder tubers are introduced into the surface of the embankment, the formation of slopes occurs in four stages: the formation of a natural slope, a limiting equilibrium slope, a shedding slope and a product collapse slope.
