Forage Harvester Crop Processor Gap Positioning for CSPS and Power Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing forage harvesters face challenges in achieving high corn silage processing scores (CSPS) while managing power consumption, as improvements in processing quality often lead to increased power demands.
Innovation Solution
A crop processing system with a positioning adjustment system that adjusts the relative position of the processing gap between crop processor rolls and the inlet channel, allowing operators to balance processing quality and power consumption by directing crop flow towards one roll or aligning it with the gap, using actuators to move the processor or inlet channel components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the crop is directed towards the rear roll of the crop processor to improve processing quality, then the corn silage processing score increases, but the power consumption increases
Solution Approach 1:
The patent implements a positioning adjustment system that allows dynamic repositioning of the processing gap relative to the inlet channel center during operation. This enables the system to adapt between different processing modes: directing more crop to the rear roll for higher processing quality when needed, or aligning the gap with the inlet channel for reduced power consumption, thus resolving the contradiction between processing quality and power usage
2Manufacturing precision
If the processing gap is positioned to maximize crop processing quality, then the corn silage processing score improves, but the system becomes less adaptable to varying operational conditions
Solution Approach 1:
The positioning adjustment system transforms a static processing gap configuration into a dynamic one, allowing the system to adapt to varying operational conditions such as different crop types, moisture levels, and power availability. The system can switch between optimization modes as needed
3Use of energy by moving object
If the processing gap is aligned directly with the inlet channel center, then power consumption is reduced, but the crop processing quality decreases
Solution Approach 1:
The system allows operators to dynamically adjust the processing gap position based on real-time operational requirements. When power conservation is prioritized, the gap aligns with the inlet channel center for efficient power usage. When processing quality is prioritized, the gap can be repositioned to direct more crop material to the rear roll, thus resolving the trade-off between energy efficiency and processing quality

AI summary
A crop processing system for a forage harvester includes a crop processor for processing crop including two crop processor rolls defining a processor gap therebetween for the crop to pass through. An inlet channel guides the crop to the crop processor. A positioning adjustment system is configured to adjust a position of the processing gap relative to a center of the inlet channel.
