Pivotable Bed Frame Bale Wagon Push-Off Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for unloading bales from bale wagons face challenges such as the need for mechanical assistance due to heavy bale weights, high friction, extended stroke distances that can cause pushing device buckling, and inability to handle multiple tiers or stacks.
Innovation Solution
A system featuring a mobile trailer frame with a pivotably movable bed frame and a push-off member connected to a hydraulic ram, allowing for efficient unloading of bales by spanning the bed frame width and applying a push-off force, while disconnecting from the ram during loading to prevent interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a pushing device is used to unload heavy bales from the bale wagon, then the bales can be moved off the wagon, but the pushing device must travel an extended stroke distance which can cause buckling
Solution Approach 1:
The bed frame is made pivotably movable between a first position for receiving bales and a second position for unloading bales. This dynamic repositioning of the bed frame reduces the stroke distance required for the pushing device while maintaining the capability to push off heavy bales effectively.
2Productivity
If a pushing device is used to push off bales, then bales can be unloaded, but known pushing devices are incapable of pushing multiple tiers or stacks of bales
Solution Approach 1:
The push-off member is divided into multiple segments or sections that can independently engage with different tiers of bales. This segmentation allows the single pushing device to effectively push multiple tiers or stacks of bales off the wagon, increasing both productivity and adaptability.
3Ease of operation
If the push-off member remains connected to the pushing device during loading, then unloading is facilitated, but interference with the loading process occurs
Solution Approach 1:
The connection between the push-off member and the pushing device is made dynamic and selective. The push-off member is selectably connectable to the pushing device when the bed frame is in the second position (unloading), and disconnected when the bed frame is not in the second position (loading). This dynamic connection eliminates interference during loading while facilitating easy unloading operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables safe and efficient unloading of heavy bales with reduced system size and complexity, capable of handling multiple tiers without buckling issues, and facilitating the use of bales in silage storage.
Implementation Method 1
A hydraulic ram is connected to the trailer frame. The push-off member is selectably connectable to the hydraulic ram when the bed frame is in the second position.
Implementation Method 2
a bed frame pivotably movable with respect to the trailer frame between a first position for receiving bales and a second position for unloading bales
