Round Baler Storage Space Compression Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing continuous round balers face challenges in achieving uninterrupted operation due to discontinuous material feeding during binding and ejection, leading to inefficiencies and poor bale densities, as previous solutions like multi-chamber and single-chamber systems have encountered issues with pre-bale transfer, storage space breakdown, and complex control requirements.
Innovation Solution
A method for controlling crop flow in a round baler using a storage space with adjustable conveyors and a height-adjustable press roller, where the conveyors and press roller work in conjunction to transfer pre-compacted material quickly and gently into the baling chamber, maintaining optimal compression and preventing material expansion, while the control device regulates the flow based on bale parameters and machine utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a storage space is introduced to enable continuous operation, then uninterrupted baling is achieved, but the harvested material accumulates and breaks down in the storage space
Solution Approach 1:
The patent applies preliminary action by pre-compacting the harvested material in the storage space before it enters the baling chamber. The pressing device acts on the material while it is stored, maintaining compression continuously. This prevents material breakdown by keeping it under pressure throughout the storage period, rather than allowing it to accumulate and decompose as in conventional systems.
Solution Approach 2:
The patent implements continuity of useful action by maintaining continuous pressing action on the harvested material throughout its storage period. The pressing device remains active on the material in the storage space, ensuring uninterrupted compression. This continuous useful action prevents material degradation while enabling continuous baling operation without stopping for binding and ejection.
2Manufacturing precision
If material is pre-pressed in the storage space, then bale density is improved, but the material expands again after transfer to the baling chamber
Solution Approach 1:
The patent uses the storage space as an intermediary chamber that maintains continuous compression between the picking-up device and the baling chamber. The material is pre-compacted in this intermediate space with a pressing device active throughout storage, and the compression is maintained during transfer to the baling chamber. This intermediary compression zone prevents the expansion problem by keeping the material under continuous pressure throughout the entire process.
Solution Approach 2:
The pressing device performs preliminary compression action on the material while it is in the storage space, before the material enters the baling chamber. This preliminary pressing maintains the material in a compacted state throughout storage and transfer, preventing subsequent expansion and ensuring consistent bale density.
3Device complexity
If conventional discontinuous baling is used, then machine structure is simple, but service interruptions occur during binding and ejection
Solution Approach 1:
The patent segments the baling process into two independent zones: the storage space with its own pressing device, and the baling chamber with the binding and ejection mechanisms. The storage space continuously receives and compacts harvested material independently of the baling chamber operations. This segmentation allows the baling chamber to perform binding and ejection without interrupting the continuous supply of pre-compacted material from the storage space, thereby maintaining simple overall structure while achieving operational continuity.
4Ease of operation
If a dosing conveyor is used to control material flow, then crop flow regulation is improved, but the system becomes more complex and susceptible to failure
Solution Approach 1:
The pressing device in the storage space performs a dual function: it both compacts the harvested material and regulates its flow into the baling chamber. The material flow control is achieved through the pressing action itself rather than through a separate dosing conveyor system. This self-service approach eliminates the need for complex additional control mechanisms while maintaining effective crop flow regulation.

AI summary
The method involves extending storage space (14) up to an inlet region of pressing chamber (3), which is provided with a device for wrapping a finished bale with binding material. A control or regulating device is arranged in pressing chamber, to which crop transducer (10) and cutting and/or delivery unit (11) are connected, so that press operation is controlled through various phases and predefined bales are produced at maximum machine utilization by regulating determined desired press time.
