FIELD: engines and pumps.SUBSTANCE: proposed dispenser comprises frame, unloading flute equipped with adjusting shutter and accumulation bin arranged there above and secured at stationary support. Spring secured at fixed support is secured to flute case from side opposite the drive. Unloading flute is oscillated by three-phase linear induction motor. Secondary element of three-phase linear induction motors is composed by spring-loaded rod rigidly coupled with unloading flute and arranged on drive side. Operation of three-phase linear induction motors is controlled by control system with its input connected with AC three-phase circuit. Winding of three-phase linear induction motors is connected with motor control system output. This dispenser also comprises the spring arranged on side opposite the drive, its one end being connected with the case and opposite end secured at fixed support.EFFECT: simplified drive, decreased weight, sizes and costs, adjustable oscillation frequency, higher reliability and efficiency.1 dwg |
