FIELD: controlling centrifugal vibrators used for handling loose materials during their transport and treatment.
SUBSTANCE: proposed device designed for automatic starting and stopping of bin-mounted centrifugal vibrators used for cleaning bin walls from sticking loose materials during their transport and treatment by turning on their motors as soon as conveyed material stops falling from bin to feeder or intake container and turning them off upon recovery of material falling process has push-button switch and drive contactor; newly introduced in device are permanent-magnet rocker arm, ferreed contact, stabilizing power pack, current-limiting resistor, delay element, threshold element (Schmitt flip-flop), amplifier, optical triac, and electromechanical relay.
EFFECT: facilitated servicing, enhanced effectiveness of using bin-mounted vibrators.
