Packer Roller Frame Rotation for Tillage Depth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural soil tillage machines require complex and numerous adjustment elements for height adjustment and folding to comply with transport width regulations, limiting flexibility in adapting to uneven surfaces and complicating the process of meeting legal transport width requirements.
Innovation Solution
The design features a soil tillage machine with a packer section's roller frame oriented transversely to the forward direction, rotatably mounted on the frame construction with a stop element to limit rotation, allowing for simplified depth adjustment and flexible ground adaptation, and includes a frame construction with adjustable sections that can be stored or rearranged to meet transport width constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the packer section is attached to the frame construction in a height-adjustable manner using hydraulically operated cylinders, then the depth adjustment capability is improved, but the device complexity increases due to numerous adjustment elements and complex control devices
Solution Approach 1:
The packer section is divided into multiple independently adjustable packer units, each capable of individual depth adjustment. This segmentation allows localized adaptation to uneven surfaces without requiring complex centralized height adjustment mechanisms, thereby reducing overall device complexity while maintaining depth adjustment capability.
Solution Approach 2:
The packer section incorporates dynamically adjustable components that can adapt their position and orientation during operation. The roller frame is designed to allow rotational movement and height adjustment through simpler mechanical means rather than complex hydraulic systems, enabling flexible ground adaptation with reduced complexity.
2Adaptability or versatility
If folding stops are designed to limit movement after pivoting of machine segments, then compliance with legally required transport width is achieved, but the device complexity increases due to correspondingly complex folding stops
Solution Approach 1:
The folding mechanism incorporates pre-positioned stops and mechanical limiters that automatically prevent excessive pivoting of machine segments. These built-in mechanical constraints ensure compliance with transport width requirements without requiring complex active control systems or sophisticated folding stop mechanisms, thereby reducing device complexity while maintaining regulatory compliance.
3Adaptability or versatility
If the roller frame is rotatably mounted on the frame construction with a stop element to limit rotation, then the flexibility in adapting to uneven surfaces is improved, but the device complexity increases due to additional mounting mechanisms
Solution Approach 1:
The roller frame is rotatably mounted on the frame construction, allowing it to dynamically adapt its orientation to uneven ground surfaces. This rotational freedom is limited by simple stop elements that prevent excessive rotation, providing flexible ground adaptation through straightforward mechanical means rather than complex active control systems, thereby maintaining adaptability while minimizing mounting mechanism complexity.
