Adjustable Rotor Interrupter for Crop Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crop processing assemblies in agricultural combines face challenges in efficiently separating grain from plant debris due to varying crop conditions and types, requiring a high-capacity system that is adjustable and adaptable.
Innovation Solution
The introduction of a rotor assembly with a support structure that includes adjustable interrupters, which can be positioned radially inward or outward to optimize grain separation, featuring variable interrupter lengths and orientations, and the ability to be coupled through electronic or mechanical interfaces for optimal performance based on crop type and conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed interrupter configuration is used, then device complexity is reduced, but adaptability to different crop conditions deteriorates
Solution Approach 1:
The interrupter configuration is made adjustable and reconfigurable during operation or between operations, allowing the system to adapt to different crop conditions. The support structure includes multiple interrupter receivers that can selectively receive different interrupter types (square stock, round bar, tine) and positions, enabling dynamic adjustment of the rotating assembly's performance characteristics.
Solution Approach 2:
The support structure is divided into multiple sections with multiple interrupter receivers distributed along its length. Each receiver can independently receive different interrupter types, allowing segmented adjustment of the interrupter configuration. This segmentation enables flexible adaptation to different crop conditions without requiring complete system redesign.
2Productivity
If variable interrupter configurations are implemented, then grain separation efficiency is improved, but device complexity increases
Solution Approach 1:
The support structure and interrupter receivers are designed with universal compatibility to accept multiple types of interrupters (square stock, round bar, tine) in multiple positions. This multi-functionality allows a single support structure to serve various grain separation needs by simply changing the interrupter configuration, rather than requiring multiple dedicated structures for different crop conditions.
3Productivity
If interrupters extend further radially inward, then grain separation capability is improved, but risk of damage to rotating portion increases
Solution Approach 1:
The interrupter extension length is made variable through selective positioning in different receivers along the support structure. Operators can adjust the radial extension of interrupters based on crop conditions, allowing maximum extension for difficult separations while limiting extension for delicate crops or when lower separation intensity is sufficient, thereby balancing productivity and reliability.

AI summary
A rotor assembly for harvesting a crop. The rotor assembly has a rotating portion defined along a rotation axis, a surrounding assembly at least partially surrounding the rotating portion, the surrounding assembly having at least one separation grate coupled to a support. The support defines an inner surface and has at least one interrupter receiver. The at least one interrupter receiver is selectively coupleable to an interrupter to position the interrupter radially inward of the inner surface towards the rotation axis.
