发明名称 ARMORED FACE CONVEYOR
摘要 An armored face conveyor includes a plurality of line pans positioned adjacent to one another, a plurality of flight bars, and a connecting member. Each line pan includes a race having an outer race face and an inner race face. The plurality of flight bars extend laterally across the line pans and are received by the race. Each flight bar includes an end having an upper guide surface and a lower guide surface. The connecting member extends through the plurality of flight-bars and couples the flight-bars to one another. Lateral movement of any one of the flight-bars that causes the upper guide surface to contact the outer race face substantially simultaneously causes the lower guide surface to contact the inner race face.
