Abstract
A tandem drive assembly, sometimes called a drive or head section, for a belt conveyor having a pair of drive pulleys arranged in tandem, in which the main drive frame comprises separate, ground-engaging, foot members located respectively inbye and outbye of the drive pulleys, and a pair of longitudinal side members interconnecting the foot members. In the example illustrated, the side members are I-beams angularly inclined upwardly from the outbye foot member to the inbye foot member. The drive pulleys are rotatably journaled in bearings mounted on upper, angularly inclined surfaces of the side members to support the inbye drive pulley at a higher level than the outbye drive pulley. The lower surfaces of the side frames are likewise angularly inclined and provide ground level clearance through the sides of the main frame for access by a scoop or shovel to the area beneath the drive rollers where dust and fines are deposited by the conveyor belt.
