Adjustable Corn Header Divider Point for Lodged Crop Harvesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corn head dividers in agricultural harvesters are not optimally suited for varying crop conditions, particularly when harvesting lodged or down corn crops, as they lack height adjustability, which complicates accurate alignment and efficient harvesting.
Innovation Solution
A corn head divider with an extendable and retractable height configuration, allowing the adjustable divider point to be increased or decreased for improved alignment and harvesting performance across different crop conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed height divider is used, then the structure is simple and easy to manufacture, but it cannot accommodate varying crop conditions such as lodged or down corn crops
Solution Approach 1:
The divider height is made adjustable through a telescopic mechanism with movable and fixed segments connected by pins and springs. This allows the divider to dynamically change its height configuration to adapt to different crop conditions, transforming a static structure into a dynamic one that can respond to varying harvesting requirements.
Solution Approach 2:
The divider is segmented into multiple height sections (movable segment and fixed segments) that can be independently positioned. This segmentation allows the divider to be divided into adjustable portions, enabling flexible height configuration while maintaining structural integrity through pin connections and spring mechanisms.
2Productivity
If the divider height is made adjustable for different crop conditions, then harvesting performance is improved, but the device complexity increases
Solution Approach 1:
The telescopic mechanism enables dynamic height adjustment of the divider, allowing operators to optimize divider height for different crop conditions such as lodged or down corn. This dynamic capability directly improves harvesting performance by ensuring proper crop alignment and flow into the processing mechanism.
Solution Approach 2:
The spring mechanism automatically provides tension and maintains the divider in its adjusted position without requiring additional active components or complex control systems. The spring's elastic properties enable self-sustaining force application, reducing the need for external power sources or complex actuation mechanisms.
3Measurement precision
If a fixed divider configuration is used, then the mechanism is simple, but alignment accuracy with corn rows varies with crop conditions
Solution Approach 1:
The adjustable height mechanism allows the divider to dynamically adapt its position to match varying crop conditions, ensuring consistent alignment accuracy whether the corn is standing upright or lodged. This eliminates the alignment problems inherent in fixed-height dividers when crop conditions change.
Solution Approach 2:
The divider's height parameter can be changed to optimize alignment with corn rows under different conditions. By adjusting the height parameter of the divider, the system maintains accurate alignment and proper crop flow regardless of whether the corn is standing or lodged, directly addressing the alignment accuracy issue.

AI summary
A corn head assembly for an agricultural harvester includes a plurality of row units for processing corn plants in rows. Adjustable dividers are provided between adjacent row units to direct laterally adjacent corn plants into adjacent row units. Each adjustable divider has an adjustable divider point with an adjustable operating height profile between a shorter, lowermost position and a taller, uppermost position to adjust the operating height of the adjustable divider for different harvesting conditions.
