Baler Feed Bar Coupling for Adaptive Collection and Feed Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing balers face inefficiencies in switching between collection and feed modes due to varying crop quantities, leading to suboptimal conveyance of crop from the collection chamber to the press chamber.
Innovation Solution
A conveyor system with a feed bar comprising a first and second bar part connected by a coupling, allowing rotation in one direction with a restoring force and preventing rotation in the opposite direction, guided by a feed collection lever in collection mode and partially by a feed lever in feed mode, enabling efficient switching between modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single feed bar is used for both collection and feed modes, then device complexity is reduced, but the ability to adapt to different crop quantities and conveyance requirements deteriorates
Solution Approach 1:
The feed bar is divided into a first bar part and a second bar part that can rotate relative to each other about the feed axis. The first bar part comprises feed tines for conveying crop, while the second bar part comprises a feed collection lever. This segmentation allows each part to be optimized for specific functions while maintaining overall adaptability through their relative rotation capability.
Solution Approach 2:
The coupling between the first and second bar parts allows them to rotate relative to each other, enabling dynamic adjustment of the feed bar configuration. In collection mode, the bar parts are coupled together; in feed mode, they can rotate relative to each other to achieve the required movement paths for different operational requirements.
2Adaptability or versatility
If separate collection and feed bars are used, then adaptability to different crop quantities is improved, but device complexity and construction costs increase
Solution Approach 1:
The feed bar is designed as a multi-functional device that can perform both collection and feed operations. The first bar part with feed tines and the second bar part with feed collection lever work together in different configurations to achieve both collection mode and feed mode functionalities, eliminating the need for completely separate bars.
Solution Approach 2:
The invention merges the collection bar and feed bar functionalities into a single integrated feed bar structure. The first bar part and second bar part are connected through a coupling that allows them to function together as a unified system, reducing the total number of components while maintaining separate operational capabilities.
3Device complexity
If the feed bar is guided exclusively by the feed collection lever, then construction complexity is minimized, but the precision of feed conveyance into the press chamber deteriorates
Solution Approach 1:
Different parts of the feed bar are guided by different mechanisms according to their specific functional requirements. The second bar part (feed collection lever) is guided by a collection guide element for collection mode, while the first bar part (feed tines) is guided by a feed guide element for precise feed conveyance into the press chamber. This localized guiding approach optimizes both simplicity and precision where needed.

AI summary
A conveyor for a baler has a feed bar with first and second bar parts connected by a coupling such that, from a stop position, the bar parts are rotatable relative to each other in a rotational direction against a restoring force and coupled to each other in the stop position to prevent rotation in opposite rotational direction. The conveyor conveys crop within a collection chamber toward a press chamber in collection mode and from the collection chamber into the press chamber in feed mode by feed tines of the first bar part. The conveyor guides the first bar part in collection mode by a feed collection lever of the second bar part and by force transmission via the coupling and guides the first bar part in feed mode partially by a feed lever of the first bar part by rotating the bar parts relative to each other.
