Changes and improvements to the harvester since the last Washington State University Field Evaluation
The last time we ran one of our prototypes for Washington State University to field test was in 2007, and we have made a number of changes and
improvements to the design since then.
Here is an outline of the improvements we've made that will be included in the next harvester that we build.
Improved Optical Spear Detector
Switched to a beam-break type system - Simpler and more reliable
More accurate - better cutting - improved yield
No moving parts - More reliable
Eliminates timing adjustments
Improved air cylinders
Smaller bore for better stroke length repeatability - less collateral damage - better yield
Designed for extremely rugged conditions
Reduced blade width - less collateral damage
More Cylinder Info
V-belt guided - won't run off pulleys
Eliminated pendant controls
Simpler harvester operation
Eliminated V-belt from compressor
Fewer parts - better reliability
Eliminates an adjustment
Eliminated V-belt from alternator
Fewer parts for better reliability
Eliminates an adjustment
Redesigned Air Distribution System
Shorter port hoses - improved cylinder response - less collateral damage
Added Check valves - improved stroke repeatability - less collateral damage
Independent air valve supply lines - improved stroke repeatability - less collateral damage
Electronic air regulation - Tight regulation for better repeatability - less collateral damage
Simplified Header Height Control
Only one moving part - better reliability
Analog sensor makes for more accurate bed height tracking - better cutting - improved yield
This is a clip of our harvester at work in Pasco Washington in 2007. This
clip shows pretty clearly how the machine functions. Notice how
much white is on the bottom of the spears - we were cutting pretty deep!
