Variable Baling Chamber for Continuous Round Bale Formation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing continuous balers face issues such as non-uniform bale formation, difficulty in binding material placement, complex transfer mechanisms, and high energy consumption due to fixed chamber dimensions, leading to inefficiencies and increased machine complexity.
Innovation Solution
A baler design with a variable baling chamber that allows continuous bale formation by transitioning crops through a feeding channel and starter rollers, enabling simultaneous bale rotation and binding, while maintaining constant pressure and uniform distribution, using a feeding system that switches orientations to accommodate bale growth without stopping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a fixed baling chamber is used, then the structure is simple, but the bale density is limited and the final dimension is fixed and not adaptable
Solution Approach 1:
The baling chamber is designed with movable walls that can dynamically adjust their position during the baling cycle. The first wall moves to define a first baling volume, then a second wall moves to define a second baling volume, allowing the chamber to adapt its dimensions continuously rather than being fixed, thereby achieving higher and more adaptable bale density
2Reliability
If the baler stops to bind the bale, then the binding can be performed properly, but time is wasted and tractor operations are complicated
Solution Approach 1:
The baling operation is made continuous by having multiple walls that can be moved sequentially. While one wall is moving to complete a bale, another wall can begin forming the next bale, allowing the binding process to occur without interrupting the overall baling flow, thus maintaining productivity while ensuring proper binding
3Adaptability or versatility
If a variable baling chamber is used, then flexibility and bale density are improved, but the device complexity increases
Solution Approach 1:
The variable baling chamber is segmented into multiple movable walls (first wall, second wall, third wall, fourth wall) that can be controlled independently. This segmentation allows each wall to perform specific functions at specific times, simplifying the control logic for each individual component while achieving complex overall functionality through coordinated operation

AI summary
A baler (1) connectable to a tractor for providing round bales (B) comprises: a baling chamber (2) for receiving crops for forming the bale (B), the baling chamber (2) being supported on a wheel axle; a conveying assembly (3), including a belt (30) which at least partially delimits the baling chamber (2) for imparting a rotating movement to the crops contained in the baling chamber (2); a pick-up device (5), configured for picking-up the crops from a field; a feeding system (4), configured for feeding the crops to the baling chamber (2); a binder (6), configured for binding a formed bale with a fastening element (60). The binder (6) is positioned at a lower height than the baling chamber with respect to the ground surface on which the baler rests, and is configured to guide the fastening element into the baling chamber along an upwardly trajectory.
