摘要

Investigation of various technological processes for the implementation of transport movement using vibratory conveyor machines for heat exchange processing of bulk materials was carried out, which showed the effectiveness of drive mechanisms with a combined unbalanced vibration system. Graphoanalytical analysis of power and moment disturbances during the generation of working vibrations made it possible to predict and ensure the necessary trajectory of bulk material movement without an additional transport device. With the help of the developed research vibrating dryer with a flexible transport body, the kinematic and energy characteristics of the exciter were experimentally obtained, which confirmed the results of mathematical modeling and substantiated the main parameters of the operating mode for advancing the technological load along the processing zone. Comparative studies of the characteristics of the movement of loose masses of rapeseed and soybeans, conducted on a research model and a classic belt conveyor, showed an increase in the speed of raw material transportation by almost two times and a decrease in energy consumption for the process using the vibration wave scheme by 1.6 times.
