Feeder Faceplate Angle Adjustment via Scissor Jack Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural harvesters lack a simple and efficient method to adjust the fore-aft angle of the feeder faceplate, which is crucial for accommodating different headers and crop conditions.
Innovation Solution
A scissor jack assembly is integrated into the feeder body to rotate the faceplate relative to the feeder body, allowing for adjustable fore-aft angle adjustments, facilitated by a threaded shaft with interconnected scissor jacks and pins, enabling manual or motorized operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the feeder faceplate angle is adjusted to accommodate different headers and crop conditions, then the adaptability and harvesting efficiency are improved, but the device complexity and operational difficulty increase due to lack of simple adjustment mechanism
Solution Approach 1:
The faceplate is designed to be movable rather than fixed, allowing it to rotate about a horizontal axis to change the fore-aft angle. This dynamic capability enables the faceplate to adapt to different headers and crop conditions while maintaining a relatively simple scissor jack-based adjustment mechanism that does not require complex hydraulic or electrical systems.
2Ease of operation
If manual adjustment of the faceplate angle is implemented, then the ease of operation is improved, but the time required for adjustment and productivity are worsened
Solution Approach 1:
The adjustment mechanism uses periodic rotation of the scissor jack assembly to achieve faceplate angle changes. The operator can rotate the scissor jack in discrete steps to adjust the faceplate to different angles, providing a balance between ease of operation and adjustment time that is more efficient than complex hydraulic systems while requiring less time than完全没有自动化系统.
