DUAL DRIVE CONVEYOR SYSTEM WITH VIBRATIONAL CONTROL

摘要

A dual drive conveyor system which has a vibration control mechanism (103) for adjusting the application of vibratory force to the material-conveying member (5) without changing the direction of the resultant line of vibratory force generated thereby, wherein the vibration generator (3) connected to the material-conveying member includes a pair of eccentrically weighted master shafts (19 and 21) driven by a first drive motor (57), and a pair of opposing parallel counter-rotating eccentrically weighted slave shafts (15 and 17) driven by a second drive motor (85), the master and slave shafts rotating in such manner that direction of the resultant line of vibratory force is substantially only parallel with the longitudinal centroidal axis of the material-conveying member (5).
