CropHawk Draper Platform Operators Manual 15
General Platform Information
8. Draper Belts.
The
MidWest
platform operates two types of Draper belts.
1.
The outer Draper belts conveys the crop to the
centre feed belt . The outer draper belts are 915
mm wide and have a V form guide moulded to the
centre of the belt. This design ensures true
alignment and allows for the belt to be reversed.
The belt is driven hydraulically via a vulcanised
drive roller and is tensioned by the inner idler roller.
2.
The centre feed belt conveys the crop to the feed drum, which
delivers the crop to the combine. The centre belt is 1500 mm wide
and has a V form guide moulded to the left hand side of the belt. The
belt is driven hydraulically via a steel drive roller and is tensioned by
the front idler roller.
9. Hydraulics / Electrics
The
MidWest
platform contains two separate hydraulic systems.
1.
The self contained, fully integrated hydraulic system drives the draper belts.
The feeder house drive shaft from the combine is connected to an input
drive shaft on the platform via a PTO shaft. The accelerator gearbox is
mounted on the input shaft and drives the hydraulic pump. The draper con-
trol circuit is split between the lateral drapers and the centre draper. The belt
speeds are independently controlled by a dual flow control incorporating a
relief valve. The oil is filtered then returned to the reservoir tank.
2.
Dependant on the combine ‘s hydraulic system is the reel
drive and reel cylinders. This system operates from the
combines hydraulics allowing full in cab control.
Electrics
The electrical system and sensors are integrated into the
combines operating system, and include reel speed control,
lighting and allowing for full platform recognition by the combine.
