Title (EN) OVERHEAD DRIVE BAR SCREEN
(FR) CLASSEUR A BARREAUX COMMANDES PAR LE HAUT
Abstract:
(EN) Two racks of parallel spaced bars (28, 30) are supported for oscillatory motion from overhead drive shafts (52, 66) having eccentric cam surfaces (60, 62). A first drive shaft (52) is driven by a belt (50) connected to a motor (44), and a second shaft (66) is connected to the first shaft (52) for synchronized movement by a rigid link (68). The bars (28, 30) are clamped to bar support beams (78, 79) without the need for bolts to extend through individual bars. The support beams are connected by side frames (76, 82) to the eccentric cam surfaces (60, 62).
(FR) Deux rangées de barreaux (28, 30), espacées parallèle sont portées pour avoir un mouvement oscillant par des arbres d'entraînement par le haut (52, 66) présentant des surfaces de came excentriques (60, 62). Un premier arbre d'entraînement (52) est entraîné par une courroie (50) reliée à un moteur (44) et un second arbre (66) est relié au premier arbre (52) pour avoir un mouvement synchronisé au moyen d'une liaison rigide (68). Les barreaux (28, 30) sont fixés sur des poutres de support (78, 79) des barreaux sans utiliser de boulons traversant les barreaux individuels. Les poutres de support sont reliées par des cadres latéraux (76, 82) aux surfaces de cames excentriques (60, 62).
