Inter-Belt Crop Divider for Balanced Agricultural Header Intake
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural harvesters face challenges in evenly distributing crop material to laterally adjacent threshing/separating rotors, particularly in uneven terrain conditions, leading to potential overloading or uneven distribution.
Innovation Solution
An agricultural header with a crop divider positioned laterally between center draper belts, featuring a panel and shingling that overlaps the belts, to separate and evenly distribute crop material to the harvester, preventing overloading and ensuring balanced intake into the harvester.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If crop material is fed from side draper belts to center draper belts without separation, then the harvester can process crop material continuously, but the crop material distribution becomes uneven causing overloading of laterally adjacent rotors
Solution Approach 1:
The crop divider assembly divides the crop material flow into separate channels using a panel and shingling structure. The panel creates a physical barrier that segments the incoming crop material from side draper belts, directing it to specific center draper belts. This segmentation ensures balanced distribution to laterally adjacent rotors while maintaining continuous processing capability.
2Manufacturing precision
If a crop divider is added to separate crop material streams, then crop material distribution uniformity improves, but the device complexity increases
Solution Approach 1:
The crop divider assembly is integrated with the existing draper belt system by positioning the panel and shingling between the side and center draper belts. The shingling overlaps both the panel and the center draper belt, merging the divider function with the existing material handling structure. This integration achieves crop separation while minimizing additional complexity.
3Manufacturing precision
If the crop divider panel extends vertically above the center draper belts, then crop material separation effectiveness improves, but the risk of material buildup between the panel and belts increases
Solution Approach 1:
The shingling provides a curved or angled transition surface between the vertical panel and the center draper belt. This curved geometry prevents sharp corners where material could accumulate, allowing crop material to flow smoothly from the panel onto the belt. The shingling effectively eliminates material buildup zones while maintaining separation effectiveness.

AI summary
An agricultural header comprises a first side draper belt, a second side draper belt, a first center draper belt, a second center draper belt, and a crop divider. The first and second center draper belts are positioned laterally between the first and second side draper belts which extend laterally outwardly in opposite directions away from the first and second center draper belts. Each of the first and second side draper belts are arranged to feed crop material laterally inwardly, and each of the first and second center draper belts are arranged to feed crop material rearwardly for processing by the agricultural harvester. The crop divider is positioned laterally between the first and second center draper belts to separate crop material fed laterally inwardly from the first and second side draper belts respectively to the first and second center draper belts.
