Angled Beveled Row Cleaner Wheel Debris Shedding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing row cleaner systems suffer from debris clogging due to the collection of soil and ground debris on the rotating wheels, which impairs their performance in no-till farming applications.
Innovation Solution
A row cleaning/closing wheel design featuring a cupped or arched shape with beveled teeth that are angled to prevent debris collection, allowing the teeth to exit parallel to the ground surface and intermesh during operation, thereby reducing clogging and enhancing cleaning and closing actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional row cleaner wheels with straight teeth are used, then the wheel can rotate and perform cleaning action, but debris and soil material collect on the tooth surfaces causing clogging and performance degradation
Solution Approach 1:
The patent applies parameter changes by modifying the tooth geometry from straight to angled/beveled configuration. The teeth are angled at approximately 45 degrees relative to the wheel circumference, creating a self-cleaning effect where debris is shed rather than accumulated during rotation. This geometric parameter change resolves the clogging issue while maintaining cleaning effectiveness.
Solution Approach 2:
Instead of designing teeth that actively scrape debris off the surface, the patent inverts the approach by designing teeth that passively shed debris through their angled geometry. The beveled surfaces cause debris to naturally detach and fall away during the upward rotation phase, eliminating the need for active debris removal mechanisms.
2Productivity
If the row cleaner wheel teeth are designed to intermesh for improved cleaning action, then cleaning effectiveness increases, but the complexity of wheel alignment and installation increases
Solution Approach 1:
The patent employs asymmetry in the tooth design where adjacent wheels have teeth oriented in opposite directions (one wheel teeth angle clockwise, the other counter-clockwise). This asymmetric configuration creates natural intermeshing action that enhances cleaning effectiveness while the symmetry of the overall system maintains simple alignment requirements.
Solution Approach 2:
The patent designs the wheels with identical dimensions, tooth counts, and mounting hole patterns, creating equipotential conditions that simplify installation. Both wheels can be mounted using the same procedure and alignment references, reducing installation complexity despite the enhanced intermeshing action.
3Productivity
If the wheel body is designed with cupped or arched shape, then debris removal effectiveness improves, but the manufacturing complexity increases
Solution Approach 1:
The patent applies curvature by designing the wheel body with a cupped or arched shape rather than a flat profile. This curved geometry creates a self-draining effect where debris is naturally directed toward the outer edges and shed during rotation. The curvature is achieved through standard metal forming processes, maintaining manufacturing feasibility.
Solution Approach 2:
The patent modifies the wheel body geometry parameter from flat to curved/cupped. This parameter change enhances debris removal by creating a slope that directs material outward during rotation. The curvature radius and depth are optimized to balance debris removal effectiveness with manufacturing simplicity.
