Windguard Assembly with Pivotable Tines for Baler Crop Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Many existing windguard designs for agricultural balers suffer from dead spaces where crop material is not held closely against the pickup tines, leading to inefficiencies in crop feeding and bale formation.
Innovation Solution
A windguard assembly with a rotating roller and a pivotably mounted tine assembly, where the tines are positioned closer to the crop flow and the pickup roll, effectively eliminating dead spaces and improving crop compaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional windguard designs are used, then the structure is simple, but dead spaces are created where crop material is not held closely against the pickup tines
Solution Approach 1:
The windguard incorporates a pivotable tine assembly that can rotate about the roller's axis of rotation, allowing the tines to dynamically adjust their position to follow the crop flow path and eliminate dead spaces, thereby improving crop holding effectiveness while maintaining reasonable structural complexity
Solution Approach 2:
The windguard is divided into a roller portion and a separately pivotable tine assembly, allowing independent optimization of each component's function and enabling the tines to be positioned more effectively along the crop path without overcomplicating the overall structure
2Manufacturing precision
If the tine assembly is positioned closer to the crop flow, then crop compaction is improved, but the device complexity increases due to the pivotable mounting mechanism
Solution Approach 1:
The pivotable mounting allows the tine assembly to automatically adjust its position dynamically, ensuring consistent crop compaction as the tines follow the natural crop flow path without requiring complex control mechanisms or multiple adjustment points
3Loss of substance
If the windguard prevents windblown losses, then crop material retention is improved, but the feeding mechanism complexity increases
Solution Approach 1:
The pivotable tine assembly dynamically adapts to crop flow conditions, providing effective wind protection and preventing windblown losses through a single degree of freedom rotation rather than requiring multiple active control mechanisms
Solution Approach 2:
The tine assembly uses the natural force of crop flow to drive its own pivoting motion, eliminating the need for external actuators or complex control systems while still achieving effective crop material retention

AI summary
A windguard assembly for a baler that is configured to either limit or prevent crop material from being blown away by the wind during feeding of the crop material into a bale chamber of the baler. The windguard assembly includes a roller that is configured to rotate about an axis of rotation. The roller includes a plurality of crop engaging surfaces that are configured to transport the crop material toward the bale chamber. The windguard assembly also includes a tine assembly that is pivotably mounted with respect to the roller about the axis of rotation. The tine assembly includes a transversely-mounted shaft and a plurality of axially spaced-apart tines extending from the shaft.
