Mathematical model of indicators determination of quality root crops harvesting and potato energy saving technology in high humidity soil condition

Abstract

Existing machines for harvesting root crops and potato tubers perform the technological process in conditions of high soil moisture, which negatively affects to the quality of harvesting as a result of a decrease in the completeness of separation of marketable products. To increase the separating capacity of slotted devices for cleaning root crops, it is proposed to improve the method of heating the separating surface with hot exhaust gas from the power plant of a harvesting machine or drive. The FSC VIM has developed a separating system for harvesting root crops and potatoes at high humidity using the heat of the exhaust gases of the power plant. In order to determine the optimal values of the developed separating system, as well as recommendations for subsequent changes in the design and technological parameters of harvesting machines, a mathematical model has been developed for calculating the quality of harvesting root crops and potatoes using energy-saving technology in conditions of high soil moisture. The values of finding the completeness of separation by expression are presented, depending on the heap mass of the root crops and potatoes coming from the digging to the separating working bodies, as well as the coefficient K_С of the change in the structural moisture of the soil.
