Upper Belt Conveyor Compressing Crop Against Center Conveyor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural harvesting heads with endless belt conveyors have not been completely satisfactory in efficiently moving and compressing crop material from the ends to the central region and into the feederhouse, as previous adaptations such as fingers on the feed roller have not effectively addressed the need for improved feed systems.
Innovation Solution
The proposed agricultural harvesting head incorporates a frame with lateral side conveyors, a central conveyor, and an upper endless belt conveyor that compresses and directs cut crop material rearward into the feederhouse, utilizing diverter rollers and a multi-region endless belt configuration to efficiently engage and compress the crop material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional feed rollers with fingers are used to move crop material, then the crop material can be engaged and moved rearward, but the compression effectiveness and feed system reliability are insufficient
Solution Approach 1:
The feed system is divided into multiple independent conveyor belts (upper conveyor belt, lower conveyor belt, side conveyor belts) that work together. Each belt can be independently controlled and optimized for its specific function, improving overall system reliability while maintaining high productivity through coordinated operation of segmented components.
Solution Approach 2:
Multiple conveyor belts are combined to form an integrated feed system that simultaneously provides material engagement, compression, and rearward movement. The upper and lower conveyor belts work in conjunction to compress crop material between them, while side conveyor belts feed material into the system, merging multiple functions into a unified high-reliability feed mechanism.
2Productivity
If crop material is conveyed from side conveyors to central region, then lateral transport is achieved, but effective compression into a manageable mat for feederhouse transfer is not accomplished
Solution Approach 1:
The upper conveyor belt is positioned vertically above the lower conveyor belt, creating a vertical compression dimension in addition to the horizontal lateral transport. This multi-dimensional arrangement allows crop material to be compressed vertically between the belts while being conveyed horizontally, effectively forming a compact mat suitable for feederhouse transfer.
Solution Approach 2:
Different regions of the conveyor system are optimized for different functions: side conveyor belts are optimized for lateral material transport, while the region between upper and lower conveyor belts is optimized for vertical compression. This local specialization ensures efficient lateral transport followed by effective mat formation in the central compression zone.

Function Achieved in This Case
This configuration ensures effective lateral and rearward conveyance of cut crop material, compressing it into a thick, manageable mat for efficient transfer into the feederhouse, improving the overall feed system's performance and efficiency.
Implementation Method 1
an upper conveyor of the endless belt type that is disposed to receive, engage and downwardly compress an upper surface of the cut crop material conveyed rearwardly by the center conveyor
Implementation Method 2
endless belt conveyors to move crop material inwardly from the ends of the harvesting head to a central region of the harvesting head
