Inverted Windrow Assembly Width Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural vehicles, such as combines, face complexity in adjusting the width of their windrow assemblies, which affects the efficiency of crop material drying and handling, as existing mechanisms are often cumbersome and require additional locking or clamping systems.
Innovation Solution
A windrow assembly with a simple manual adjustment mechanism using side panels and linkages, allowing for easy width adjustment via a manual handle and detent arrangement, eliminating the need for additional locking mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complicated width adjusting mechanism is used in an inverted windrow assembly, then the windrow width can be adjusted, but the device complexity increases and requires additional locking or clamping systems
Solution Approach 1:
The patent inverts the conventional windrow assembly design by positioning the discharge panel at the bottom and the side walls extending upward, allowing gravity to assist in maintaining the windrow shape. This inverted configuration enables a simpler adjustment mechanism without requiring complex locking or clamping systems, as the gravity-assisted design naturally stabilizes the structure during operation.
Solution Approach 2:
The patent employs a dynamic adjustment mechanism where the side walls can be moved laterally inward and outward relative to the discharge panel to adjust windrow width. The mechanism uses a manual adjustment member connected through linkages that allow smooth, continuous adjustment without fixed locking positions, enabling the operator to dynamically adapt the windrow width to varying operational conditions.
2Adaptability or versatility
If the entire rear hood is raised or lowered to adjust windrow width in a windrower or haybine, then the windrow width can be adjusted, but the device complexity and operational time increase
Solution Approach 1:
The patent segments the windrow assembly into independent components: a fixed discharge panel and movable side walls. This segmentation allows the side walls to be adjusted independently without moving the entire rear hood structure, significantly reducing the time and effort required for width adjustment while maintaining full adaptability of the windrow configuration.
3Ease of operation
If a simple manual adjustment mechanism is used, then the ease of operation improves, but the manufacturing precision and stability of the adjustment may be compromised
Solution Approach 1:
The patent uses a dynamic linkage system connected to a manual adjustment member that provides continuous, smooth control over side wall position. The linkage geometry is designed to translate small manual inputs into precise lateral movements of the side walls, maintaining high adjustment precision while keeping the operation simple and manual without requiring complex locking mechanisms or automated systems.
