Header Automation Using Feeder Drum Position for Crop Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural harvesters face inefficiencies due to variations in crop flow and layer thickness from the header into the feeder, impacting overall operational efficiency and capacity.
Innovation Solution
A system that automatically adjusts parameters such as knife position, reel position, auger speed, and belt speeds of the header based on the detected position of a conveyor idler, using sensors and a controller to minimize variations in crop flow and layer thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual adjustment of header parameters is used, then operational simplicity is maintained, but crop flow variation and layer thickness inconsistency occur
Solution Approach 1:
The system employs sensors to detect the position of the conveyor idler and feeds this information back to the controller, which automatically adjusts header parameters. This closed-loop feedback mechanism eliminates manual adjustment while maintaining layer thickness consistency and reducing crop flow variation.
Solution Approach 2:
The header automation system performs self-adjustment based on real-time sensor data. The controller automatically modifies knife position, reel position, and auger speed without operator intervention, allowing the system to optimize its own performance and maintain consistent crop flow.
2Productivity
If fixed header parameters are used, then system simplicity is maintained, but productivity decreases due to inefficient crop flow
Solution Approach 1:
The system transitions from fixed header parameters to dynamic adjustment. The controller continuously modifies knife position, reel position, and auger speed based on real-time crop flow conditions detected by sensors, optimizing harvesting efficiency while adapting to varying field conditions.
Solution Approach 2:
The automation system changes operational parameters (knife position, reel position, auger speed) based on detected crop flow variations. This dynamic parameter adjustment optimizes the header's performance to maintain consistent layer thickness and improve overall productivity.
3Reliability
If header parameters are not adjusted, then operational simplicity is maintained, but throughput variation increases
Solution Approach 1:
The control system uses sensor feedback to detect throughput variations and automatically adjusts header parameters to maintain consistent crop flow. This feedback loop ensures reliable throughput while the system adapts to changing field conditions without manual intervention.

AI summary
A system and method for automatically adjusting one or more parameters of a header (18) of an agricultural harvester (10) for gathering a crop and feeding the crop into a feeder housing (20) includes receiving, from one or more sensors (92), a signal indicative of a position of a conveyor idler (27) of a conveyor (25) of the feeder housing (20) over time. The system and method also includes providing one or more control signals to adjust the one or more parameters of the header (18) based on variation of the position of the conveyor idler (27) over time.
