Baler Segmented Tension Panels for Bale Density Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional balers face challenges in consistently controlling the shape and density of bales, particularly in forming rectangular bales with varying crop materials, as they lack precise control over the baling chamber geometry and pressure distribution.
Innovation Solution
A baler with segmented tension panels, where each side wall is composed of independently moveable segment panels attached via pivot joints, allowing for controlled actuation and adjustment of the baling chamber's geometry and pressure distribution through an actuator system and control system, enabling precise shaping and density control of bales.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional rectangular side walls are used in the baling chamber, then the structure is simple and easy to manufacture, but the control over bale shape and density is insufficient
Solution Approach 1:
The side walls of the baling chamber are divided into multiple independently movable segment panels instead of being single rigid structures. Each segment panel can be independently actuated to adjust the chamber geometry and pressure distribution, enabling precise control over bale shape and density while maintaining structural simplicity through modular design
Solution Approach 2:
The side walls are transformed from static rigid structures to dynamic adjustable structures. Each segment panel is equipped with actuators that enable real-time adjustment of panel positions and angles during the baling process, allowing the chamber to adapt its geometry for optimal bale formation and density control
2Adaptability or versatility
If the baling chamber geometry is fixed, then the device complexity is reduced, but the adaptability to different crop materials and bale requirements is limited
Solution Approach 1:
The baling chamber geometry is made dynamically adjustable through independently controllable segment panels. Each panel can be actuated to different positions and angles, allowing the chamber to be reconfigured for different crop materials, bale sizes, and density requirements, providing high adaptability without requiring multiple fixed chamber designs
Solution Approach 2:
The chamber geometry parameters (panel angles, positions, gaps) are made variable through actuator systems. This allows continuous adjustment of chamber dimensions and pressure distribution to optimize baling performance for different materials and desired bale characteristics, transforming a fixed-parameter system into a variable-parameter system

AI summary
A baler (100) includes a frame (121) and a bale chamber structure (114) that is supported by the frame (121). The bale chamber structure (114) includes a plurality of walls (128) that cooperate to define a baling chamber (124) that extends along a longitudinal axis (126). The plurality of walls (128) shape different sides of the bale. At least one of the plurality of walls (128) includes a first segment panel (151) that is moveably attached to the frame (121) and a second segment panel (153) that is arranged in a downstream direction from the first segment panel (151) with respect to the longitudinal axis (126). The second segment panel (153) is moveably attached to the frame (121) independent of the first segment panel (151).
