Round Bale Pickup Coupling With Pivoting Transfer Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bale receiving devices for round balers have limited pivoting capability, leading to collisions and bale displacement during operation, and a gap that allows bales to fall sideways while being picked up.
Innovation Solution
A bale receiving device with a transfer element that can pivot relative to the drawbar element about a vertical axis, combined with a drawbar element that can pivot about a transverse axis, ensuring the bale is securely picked up and preventing lateral displacement, and a support section to distribute the bale's weight effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the coupling device and drawbar element are designed to taper towards the vertical axis to enable slight pivoting, then the pivoting capability is improved, but a gap is created on the side of the vertical axis into which the round bale can fall sideways
Solution Approach 1:
A transfer element is introduced as an intermediary component between the drawbar element and the contact surface. This transfer element bridges the gap created by the tapered design, preventing the round bale from falling into the gap while still allowing the necessary pivoting movement. The transfer element acts as a mediator that maintains both the pivoting capability and the bale retention simultaneously.
2Reliability
If the drawbar element is designed with limited pivoting range to prevent collisions, then the collision risk is reduced, but the curve radius that can be achieved during operation is limited
Solution Approach 1:
The coupling device is segmented into multiple independently movable components: the drawbar element that can pivot about a first axis, and the transfer element that can pivot about a second axis. This segmentation allows each component to move independently within its own range, enabling the system to achieve larger overall pivoting ranges and curve radii while each individual component remains within safe collision-free limits.
3Stability of the object's composition
If the drawbar element is made longer to improve bale pickup stability, then the stability is improved, but the device complexity and risk of bale falling into the gap increase
Solution Approach 1:
Instead of simply extending the drawbar element in one dimension, the solution introduces a transfer element that adds movement in another dimension (a second axis of rotation). This dimensional change allows the system to achieve improved bale pickup stability through the coordinated movement of multiple elements, rather than relying on a single long drawbar element, thereby managing structural complexity more effectively.
