Receiving Hopper
The receiving hopper on the rear of the machine is
hydraulically controlled. When the hopper wings are
fully open, the hopper can hold a payload up to 3.5 cubic
yards (4 cubic meters). The receiving hopper controls
are located on the joystick for ease of operation while
chip spreading.
Aggregate material is delivered by a dump truck into
the receiving hopper. The chip spreader is equipped
with a positive-latching, hydraulic-release truck hitch
that secures the chip spreader to a pull bar on the
dump truck. Rubber sealing skirts along the receiving
hopper seals the hopper to the truck dump box during
operation.
Once aggregate material is loaded into the receiving
hopper, it then moves via two hydraulic motor-driven
conveyor belts through grizzly screens to the front
spread hopper. The grizzly screens prevent oversized
aggregate and debris from entering the spread hopper.
A feed gate for each conveyor in the receiving hopper
allows more control over the amount of aggregate
being conveyed to the spread hopper in the front of the
machine.
Conveyors
The conveyors are an important part of the chip
spreader’s aggregate delivery system.
Two motor-driven conveyor belts move aggregate from
the receiving hopper to the spread hopper. Rubber
chute liners seal each side of the conveyors to prevent
spillage of aggregate. Drive, tension and suspension
for the conveyor belts are provided by various pulleys
attached to the conveyor frame. Pulleys and trough
idlers provide suspension and tension adjustment for
each conveyor belt.
Proper alignment and tension adjustment of the
conveyor belts is necessary for optimum operation and
machine maintenance.
