Double-tab baffle for agricultural baler bale wrapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural balers often result in unevenly wrapped bales due to wrapping material becoming jammed or bunched, leading to incomplete coverage and issues with hay loss and storage.
Innovation Solution
A duckbill assembly with a double-tab baffle system, featuring a frame, rollers, upper and lower baffles, and gripper tabs, ensures consistent spreading and retention of wrapping material across the bale width, preventing material from bunching and ensuring full coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a single-tab baffle is used to retain wrapping material, then the structure is simple, but the wrapping material becomes jammed or bunched causing incomplete coverage
Solution Approach 1:
The lower baffle is segmented into a double-tab configuration with two separate tabs instead of a single tab. This segmentation allows the wrapping material to be retained at multiple points across the baffle width, preventing the material from bunching or jamming in a single location, thereby ensuring more uniform wrapping coverage.
2Ease of operation
If the wrapping material is allowed to spread freely, then the application is simple, but the material bunches or pulls inwardly toward the center causing uneven wrapping
Solution Approach 1:
The lower baffle features localized retention points at specific positions across its width through the double-tab configuration. These localized features provide controlled engagement points for the wrapping material, preventing it from pulling inwardly toward the center while still allowing it to spread across the full width of the bale for complete coverage.

AI summary
A duckbill assembly of a wrapper for an agricultural baler. The duckbill assembly includes a frame, at least one roller movably connected to the frame and configured for spreading a wrapping material, an upper baffle connected to the frame, and a lower baffle connected to the frame and located underneath the upper baffle. The lower baffle has a width, a first set of grippers, and a second set of grippers. The first and second set of grippers are configured for spreading the wrapping material across the width of the lower baffle.
