Round Baler Flexible Duct System for Bale Formation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing round balers face difficulties in efficiently returning the pick-up to the start position and have complex, expensive designs, particularly in creating loops between adjacent rolls for bale formation.
Innovation Solution
The design incorporates a flexible duct system with multiple conveyors and adjustable outlets, movable rolls, and sophisticated control mechanisms to optimize bale formation, allowing for efficient material feeding and bale core initiation, while avoiding long feeding paths and enabling the feeder to perform multiple functions like cutting and conditioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a feeder moves a bale along the baler and returns to a start position, then the bale formation can be maintained, but the complexity and cost of the design increases
Solution Approach 1:
The patent extracts the bale formation function from the feeder mechanism by using a separate pick-up assembly that operates independently. The pick-up assembly returns to the start position automatically through the rotation of the baler arms, eliminating the need for a complex feeder return mechanism while maintaining continuous bale formation.
Solution Approach 2:
The baler arms themselves serve the dual function of both feeding material and forming bales. The rotation of the arms automatically positions the pick-up assembly and creates the bale chamber without requiring additional active components, making the system self-sufficient and reducing overall complexity.
2Productivity
If loops are created by incoming crop in flexible bale forming means between adjacent rolls, then bale formation is enabled, but the difficulty to return the pick-up fast enough to the start position increases
Solution Approach 1:
The pick-up assembly is positioned and prepared in advance during the rotation of the baler arms. The arms rotate to pre-position the pick-up assembly at the correct location and orientation before the actual bale formation begins, ensuring that the pick-up assembly is ready immediately when needed and eliminating delays in the return process.
Solution Approach 2:
The patent employs dynamic positioning of the pick-up assembly through the continuous rotation of the baler arms. The pick-up assembly moves with the arms in a controlled manner, allowing it to be quickly returned to the start position through the natural rotational motion of the arms rather than requiring separate active return mechanisms.
3Adaptability or versatility
If several conveyors are located close to each other, then material can be selectively forwarded, but the feeding path becomes constrained
Solution Approach 1:
The patent arranges the conveyors in a radial pattern around the central axis of the baler, utilizing the radial dimension rather than only the axial dimension. This allows multiple conveyors to be positioned close together while maintaining adequate feeding paths, as the material can be forwarded in different radial directions depending on the function required.
Solution Approach 2:
The feeding system is divided into multiple independent conveyor segments, each capable of performing specific functions (cutting, conditioning, transport). These segmented conveyors can be selectively activated and positioned to handle different material flow requirements without interfering with each other, maintaining feeding path flexibility while enabling versatile material processing.

AI summary
A round baler of the non-stop type has three arms rotating about a common axis and having rolls at their free ends. A loop may be formed between rolls of adjacent arms, wherein material is fed to the loop forming a bale from one of several outlets fed by a feeder.
