Pivotable Telescopic Frame for Seed Drill Width Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural seed drills have inflexible frame arrangements that require multiple machines with different row widths for various crops, leading to high acquisition costs and inefficiencies, as they cannot easily adjust to different planting configurations.
Innovation Solution
A pivotable and telescopic frame arrangement that allows for quick adjustment of row width and working width, enabling a single seed drill to be used for multiple crops while maintaining maximum working width and adhering to road transport dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a seed drill is designed with a fixed frame arrangement for a specific row spacing, then the structural simplicity and manufacturing ease are improved, but the adaptability to different crops and row spacing requirements deteriorates
Solution Approach 1:
The frame arrangement is designed with pivotable frame segments that can be rotated between a working position (horizontal) and a transport position (vertical), allowing the same structure to adapt to different row spacing requirements. This dynamic configuration enables a single seed drill to serve multiple crops without requiring separate fixed-frame designs for each crop type.
2Adaptability or versatility
If multiple seed drills with different frame arrangements are purchased to accommodate various crops, then the adaptability to different crops is improved, but the acquisition cost and device complexity increase
Solution Approach 1:
The frame arrangement is designed as a universal structure that can accommodate different numbers of sowing units and adapt to various row spacing requirements through pivotable segments. This multi-functional design allows a single seed drill to perform the same sowing function across different crops (e.g., maize, rapeseed, wheat) without requiring separate specialized machines for each crop type.
3Adaptability or versatility
If the frame arrangement is made telescopic to adjust working width, then the adaptability to different row spacings is improved, but the device complexity and structural complexity increase
Solution Approach 1:
The frame arrangement is divided into multiple pivotable frame segments (first frame segment, second frame segment, etc.) that can be independently rotated. This segmentation allows the working width to be adjusted by changing the configuration of individual segments while maintaining a relatively simple overall structure. The segments are connected through pivot points, enabling flexible reconfiguration without requiring complex telescopic mechanisms.
4Adaptability or versatility
If frame segments are made pivotable to adjust working width, then the adaptability to different crops is improved, but the structural complexity increases
Solution Approach 1:
The frame segments are designed with pivot connections that allow them to rotate between horizontal (working) and vertical (transport) positions. This dynamic capability enables the same physical structure to adapt to different row spacing requirements by simply changing the angular configuration of the segments, avoiding the need for complex adjustable mechanisms while maintaining versatility.
