Discharge Auger System
Ground feed from the mixing tank is discharged by an auger system consisting
of three hydraulically motor driven augers that are connected in series so that
all augers are synchronized as well as started and stopped together.
If any
motor malfunctions, the movement of material through the augers will stop
immediately.
The discharge auger unloads material to any point within a 300
degree radius. The length of the unloading auger is approximately 12 feet,
without any extensions. By adding a 3’ or 6’ folding extensions, the length can
be increased. A transport cradle is provided for holding the unloading auger in
position during transport.
NOTE: Always activate the hydraulic variable speed control valve to engage
the discharge augers before opening the discharge auger shut-off door. When
the mixing tank has been unloaded, close the discharge auger shut-off door
then shut-off the hydraulic variable speed control valve .
OPERATION (cont.)
Discharge Auger Door & Variable Speed Valve
A variable speed valve with a pressure relief controls the hydraulic motors
which operate at a single constant speed determined by the speed of the
tractor PTO, or at a variable speed determined by the valve. A discharge auger
shut-off door is provided to regulate the amount of feed passing into the
discharge auger.
Needle Valves
An adjustable needle valve is provided on each hose of the discharge auger
rotation to control the speed of auger swing to provide smooth rotation. Needle
valves are located at the rear of the machine by the hydraulic rotation motor.
See the Adjustment Chapter of the manual for adjustment details.
