Adjustable Row Cleaner Assemblies for Debris Clearing and Furrow Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing row cleaner systems in strip till farming face challenges in adjusting to varying soil conditions and debris, leading to ineffective debris removal and seed planting issues due to fixed geometry and inadequate closure mechanisms.
Innovation Solution
A row cleaner system with adjustable row cleaning and closing assemblies, featuring a pivotally attached actuator and lever mechanism, allows for customizable down-pressure and angle adjustment of cleaning wheels relative to the ground, ensuring optimal debris clearance and furrow closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed geometry row cleaner systems are used, then device simplicity is maintained, but adaptability to varying soil conditions and debris is poor
Solution Approach 1:
The row cleaner system employs a pivotally attached actuator that enables dynamic adjustment of the cleaning assembly angle relative to the ground. This allows the system to adapt to varying soil conditions and debris types by changing its operational geometry, transforming a static fixed-geometry system into a dynamic adjustable one that responds to field conditions.
Solution Approach 2:
The system changes the operational parameter of the cleaning assembly angle through actuator adjustment. By modifying this geometric parameter, the row cleaner can optimize its performance for different soil conditions and debris characteristics, enabling adaptability without requiring completely different system configurations.
2Productivity
If adjustable row cleaner systems are added, then debris removal efficiency is improved, but device complexity increases
Solution Approach 1:
The pivotally attached actuator provides dynamic adjustment capability that optimizes the cleaning assembly's engagement with debris. This dynamic positioning allows the system to maintain optimal cleaning geometry across varying operational conditions, significantly improving debris removal efficiency compared to fixed systems.
Solution Approach 2:
The actuator mechanism serves multiple functions: it adjusts the cleaning assembly angle for optimal debris removal, maintains consistent ground engagement across terrain variations, and can potentially accommodate different cleaning wheel configurations. This multi-functionality justifies the added complexity by delivering superior productivity.
3Ease of operation
If closing wheels are positioned far from seed slot, then furrow closure is achieved, but seed depth control and soil contact are reduced
Solution Approach 1:
The system addresses the spatial positioning problem by adding angular adjustment capability in a different dimension. Instead of only moving closing wheels forward or backward along the seed row, the actuator adjusts the angle of the entire closing assembly, allowing effective furrow closure while maintaining optimal proximity to the seed slot for precise seed depth control and soil contact.

AI summary
A row cleaner connected to a strip till machine clears mulch and other debris in strip or low till planting. A row cleaner frame assembly includes a pair of row cleaner arms and a pair of clearing wheels having toe-in alignment. The pair of row cleaner arms share a common plane and are pivotally connected at a pair of pivot points common or close to the rotational axis of a cutting disc. The cutting disc is disposed intermediate the pair of row cleaner arms. The row cleaner arms are configured to maintain the clearing wheels in close-proximity to the cutting disc to provide stretch and cut row clearing operation. An actuator pivotally adjusts the row cleaner assembly relative to the cutting disc. A pivot limiter restricts pivotal travel of the row cleaner. A row closing section lever adjusts toe and/or camber of a closing wheel.
