Single drive conveyor apparatus (10) including an elongated material-conveying conveyor having vibration-generating means (V) connected to one end thereof and vibrating the same substantially only in a direction parallel with the longitudinal centroidal axis thereof and including two pairs of parallel vibration--generating shafts (21,22 and 28,32), each pair having axial displacement relative to the other and each shaft of each pair carrying eccentrically mounted weights (35,37 and 29,33) generating equal forces and rotating in opposite directions, said pairs of shafts rotating at different speeds and each pair carrying a pair of equal force-generating and eccentric weights (35,37 and 29,33) different from that of the other, a continuous flexible drive element (76) having opposed continuums (77,78) extending around and in driving relation to each of said pairs of shafts (21,22 and 28,32), and controllably shiftable phase--adjustment/motion-altering mechanism (50) engaging each of said continuums and shortening one of said continuums (77,78) while lengthening the other as said mechanism (50) shifts to thereby controllably alter the axial displacement existing between the shafts of said two pairs.
Convoyeur à entraînement unique (10) à bande de transport allongée muni d'un moyen de production de vibrations (V) fixé à l'une de ses extrémités et n'y induisant sensiblement que des vibrations parallèles à son axe longitudinal central, et de deux paires d'arbres producteurs de vibrations (21, 22 et 28, 32) dont chacune est en mouvement axial relatif par rapport à l'autre et où chaque arbre de chaque paire porte des masselottes (35, 37 et 29, 33) excentrées engendrant des forces égales, mais tournant en sens opposé, et d'un mécanisme de variation du mouvement commandé par réglage de phase (50) en prise avec les courroies de transmission du mouvement et raccourcissant l'une d'elle (77, 78) tout en allongeant l'autre alors que ledit mécanisme (50) se décale pour commander les variations du déplacement axial existant entre les arbres des deux paires susdites.
