TM 5-3895-373-201.12.5. HopperAuger/ConveyorSystems. Thepaving machine is equipped with right and leftindependently controlled auger/conveyor systems. Eachsystem is driven by a hydraulic motor mounted on themain frame bulkhead. The main auger/conveyor systemcomponents are as follows:a.Conveyors. There are two conveyors located inthe hopper. Each conveyor consists of conveyor rollers,drive shafts, conveyor chains with drag bars, conveyordrive sprocket wheels, and drag plates. When theauger/conveyor system is turned on, the conveyors pullpaving material from the hopper back to the augers infront of the screed.b.Augers. Two spiral augers are used to movethe paving material deposited by the conveyors. Whenthe auger/conveyor drive is turned on, the spiral augersspread paving material evenly across the width of thescreed.c.Auger/Conveyor Drive System. The conveyorsand augers are driven by two hydraulic motors. Thehydraulic motors are turned on and off at the operatorswitch panel or at the screed control panels. Reversecontrol switches on the switch panel allow each conveyorand auger to be run in reverse. Speed control valvescan be manually adjusted to speed up or slow downconveyor and auger rotation. Each motor is connectedto a drive sprocket wheel and drive chain. The drivechain engages with the conveyor drive sprocket wheeland auger drive sprocket wheel. The position of themotors and sprocket wheels is adjustable for maintainingchain tension.1-10
