1.12.5. Hopper Auger/Conveyor Systems. The
paving
machine
is
equipped
with
right
and
left
independently controlled auger/conveyor systems. Each
system is driven by a hydraulic motor mounted on the
main frame bulkhead. The main auger/conveyor system
components are as follows:
a.
Conveyors. There are two conveyors located in
the hopper. Each conveyor consists of conveyor rollers,
drive shafts, conveyor chains with drag bars, conveyor
drive sprocket wheels, and drag plates. When the
auger/conveyor system is turned on, the conveyors pull
paving material from the hopper back to the augers in
front of the screed.
b.
Augers. Two spiral augers are used to move
the paving material deposited by the conveyors. When
the auger/conveyor drive is turned on, the spiral augers
spread paving material evenly across the width of the
screed.
c.
Auger/Conveyor Drive System. The conveyors
and augers are driven by two hydraulic motors. The
hydraulic motors are turned on and off at the operator
switch panel or at the screed control panels. Reverse
control switches on the switch panel allow each conveyor
and auger to be run in reverse. Speed control valves
can be manually adjusted to speed up or slow down
conveyor and auger rotation. Each motor is connected
to a drive sprocket wheel and drive chain. The drive
chain engages with the conveyor drive sprocket wheel
and auger drive sprocket wheel. The position of the
motors and sprocket wheels is adjustable for maintaining
chain tension.
