Segmented Windguard Roller for Baler Crop Feeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
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 featuring a transversely mounted roller with crop engaging surfaces and a tine assembly with independently moveable tines, allowing for closer proximity to the crop flow and improved compaction against the pickup roll.
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 is divided into multiple segments including a first windguard section and a second windguard section that can be independently positioned. This segmentation allows each section to be optimized for different regions of the pickup reel, eliminating dead spaces while maintaining overall structural manageability
Solution Approach 2:
The second windguard section is made independently movable relative to the first windguard section, allowing dynamic adjustment to accommodate varying crop conditions and reel positions. This independence enables the windguard to adapt to different operational scenarios without creating dead spaces
2Reliability
If the windguard is positioned closer to eliminate dead spaces, then crop compaction improves, but the risk of crop material being blown away during windy conditions increases
Solution Approach 1:
The windguard is segmented into multiple sections that can be independently positioned, allowing the front section to extend further forward to protect against wind while the rear section maintains close proximity for effective compaction, thus addressing both wind protection and feeding consistency requirements
Solution Approach 2:
The windguard sections can be independently positioned in multiple dimensions, allowing optimization of both the forward extension for wind protection and the lateral/closeness positioning for compaction effectiveness, resolving the contradiction through multi-dimensional adjustment

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 transversely mounted 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 mounted with respect to the roller. The tine assembly includes a plurality of axially spaced-apart and longitudinally extending tines extending from a transversely mounted shaft. One of the tines of the plurality of tines is independently moveable with respect to another tine of the plurality of tines.
