Harvester Conveyor Roller Closing Tab for Angled Chassis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conveyor roller systems for harvesters of tall and stalky plants, such as sugarcane and sweet sorghum, face material loss issues due to the inability of blocking panels to adapt to angled chassis configurations, which prevents them from effectively closing displacement openings and maintaining productivity during harvesting of multiple crop rows.
Innovation Solution
A conveyor roller structural assembly with pivotally mounted closing tabs and a connector element, such as a hinge, that allows the closing tabs to dynamically follow the angular variation of the chassis, ensuring the displacement openings are blocked without interfering with the material flow, even in machines with tapering configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blocking panels are fixedly anchored close to the pivot axis of the conveyor rollers, then the panels can effectively block the displacement openings when the rollers are in certain positions, but the panels cannot adapt to angular variation along the chassis walls and fail to follow the surface of the chassis in machines with angled configurations
Solution Approach 1:
The blocking panels are transformed from fixed structures to dynamic components that can move and rotate. Each blocking panel is connected to the chassis via a pivot axis and can rotate about this axis, allowing it to dynamically adapt its position and orientation to follow the angular variation of the chassis walls while maintaining effective blocking of the displacement openings.
Solution Approach 2:
The blocking panels are designed to change their angular position and orientation parameters relative to the chassis. By allowing the panels to rotate about pivot axes, their angular parameters can be adjusted to match the chassis wall angles, enabling them to maintain proper blocking effectiveness across different chassis configurations.
2Loss of substance
If blocking panels are used to prevent material loss through displacement openings, then material loss is reduced, but the panels cannot dynamically adapt during machine operation in the field
Solution Approach 1:
The blocking panels are designed as dynamic components that can rotate about pivot axes, enabling them to adapt during machine operation. This dynamic capability allows the panels to maintain effective blocking of displacement openings while accommodating changes in roller position and chassis angle during field operations.
Solution Approach 2:
The blocking panels are designed to automatically adjust their own positions and orientations based on the machine's operational state. The pivot axis mechanism allows the panels to self-adapt to changing conditions without requiring external control systems, enabling them to maintain blocking effectiveness autonomously during operation.
3Productivity
If the chassis walls are configured at angles to unify the processing path of harvested materials, then productivity is improved by enabling multiple crop row harvesting, but the blocking panels cannot follow the angular variation and fail to maintain proper blocking
Solution Approach 1:
The blocking panels are designed to dynamically follow the angular variation of the chassis walls through rotation about pivot axes. This dynamic capability ensures that even as the chassis walls are configured at angles to unify processing paths for multiple crop rows, the blocking panels maintain their effectiveness in preventing material loss.
