Automated Header Positioning for Agricultural Harvesters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rigidly mounted headers on agricultural vehicles are ineffective in harvesting crop material under varying terrain and crop conditions, leading to significant header loss and operator fatigue due to the need for frequent manual adjustments.
Innovation Solution
An automated adjustment system that includes sensors and actuators to automatically orient and adjust the header and feeder housing in response to terrain and crop conditions, reducing the need for manual intervention and improving harvesting efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a rigidly mounted header is used, then the structural simplicity and ease of manufacture are improved, but the adaptability to varying terrain and crop conditions deteriorates, leading to header loss
Solution Approach 1:
The header is transformed from a rigid, fixed structure to a dynamic, adjustable system. Multiple independent adjustment mechanisms enable the header to change its geometry (cutter bar angle, reel position, snout orientation) in real-time to adapt to varying terrain and crop conditions, directly resolving the contradiction between structural simplicity and adaptability
2Adaptability or versatility
If a moveable header with multiple adjustment mechanisms is used, then the adaptability to terrain and crop conditions is improved, but the device complexity and ease of operation deteriorates due to frequent manual adjustments
Solution Approach 1:
The header adjustment system operates autonomously without requiring continuous manual intervention. Sensors detect terrain profile and crop conditions, the controller processes this information, and actuators automatically adjust header components, enabling the system to serve itself and eliminate operator fatigue from frequent adjustments
3Measurement precision
If manual measurement and adjustment of header pitch angle is performed, then the initial setup precision can be achieved, but the time consumption and operator fatigue increase
Solution Approach 1:
Manual mechanical measurement and adjustment operations are replaced by an automated electronic control system. Sensors electronically detect terrain and crop parameters, the controller computationally determines optimal settings, and actuators automatically position header components, eliminating the time-consuming manual measurement and adjustment process while maintaining or improving precision

AI summary
A method of operating an agricultural vehicle having a feeder housing and a header. The method includes the steps of providing an automated adjustment system configured for adjusting at least one of: at least one header function, at least one feeder housing function, and at least one agricultural vehicle function. The automated adjustment system includes a controller and a memory operably coupled to the controller. The method includes the further steps of receiving an input from one of an operator manually inputting the input or the header automatically communicating the input, defining an origin position, calibrating an origin pitch angle of the header, adjusting a position of the header, maintaining the origin position, determining a condition, and adjusting or maintaining at least one of the at least one header function, the at least one feeder housing function, and the at least one agriculture vehicle function in response to the condition.
