Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing row cleaning systems in agricultural equipment, particularly in no-till or minimum tillage conditions, lack the ability to adjust depth automatically in response to varying soil conditions or operator commands, leading to inefficiencies and potential damage from foreign objects.
Innovation Solution
An adjustable row cleaner system with a mounting mechanism that allows for automatic depth adjustment of row cleaner wheels using pneumatic, hydraulic, mechanical, or combined actuators, enabling real-time monitoring and control from the operator's cab, ensuring optimal penetration depth and minimizing residue plugging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If row cleaner depth is fixed, then device complexity is reduced, but adaptability to varying soil conditions and foreign objects deteriorates
Solution Approach 1:
The row cleaner assembly incorporates an adjustable depth mechanism that allows the cleaner to dynamically change its operating depth. The cleaner can be positioned at multiple depth settings along the furrow, enabling it to adapt to varying soil conditions and foreign object locations rather than being fixed at a single depth position.
Solution Approach 2:
The system changes the depth parameter of the row cleaner assembly to optimize performance. By allowing the cleaner depth to vary independently from other row unit elements, the system can adjust this critical parameter in response to different soil conditions, residue levels, and foreign object positions without changing other operational parameters.
2Productivity
If row cleaner depth is manually adjusted, then device complexity is reduced, but productivity and operational efficiency deteriorate
Solution Approach 1:
The row cleaner assembly is designed to be self-adjusting within certain parameters. The floating frame allows the cleaner to automatically respond to encountered foreign objects and soil variations, performing depth adjustments without continuous operator intervention, thereby maintaining productivity while reducing the need for complex manual control systems.
Solution Approach 2:
The system incorporates depth monitoring capabilities that provide feedback on the row cleaner's position and operation. This feedback mechanism allows the system to automatically adjust depth settings based on real-time conditions, improving operational efficiency by eliminating the need for constant manual monitoring and adjustment while avoiding excessive complexity through simple sensor-based control.
3Object-affected harmful factors
If row cleaner wheels are positioned shallow, then foreign object damage is reduced, but residue plugging increases
Solution Approach 1:
The adjustable depth mechanism enables the row cleaner to dynamically position itself at the optimal depth for each operating condition. When foreign objects are detected or suspected, the cleaner can be raised to avoid damage, while in clean soil conditions it can be positioned deeper to effectively clear residue and prevent plugging, thus dynamically balancing these two opposing concerns.
Solution Approach 2:
The system changes the depth parameter of the row cleaner wheels based on operating conditions. By independently adjusting the cleaner depth parameter, the system can optimize the balance between avoiding foreign objects and preventing residue plugging, allowing the depth to vary within a range that accommodates both requirements without being fixed at a suboptimal position.
4Adaptability or versatility
If row cleaner depth is not independently adjustable, then device complexity is reduced, but adaptability to operator commands and monitoring deteriorates
Solution Approach 1:
The row cleaner assembly is segmented as an independent adjustable unit within the larger row unit structure. The cleaner depth is separated from the depth settings of other row unit elements, allowing independent control and adjustment. This segmentation enables flexible depth control tailored to specific cleaner needs without complicating the overall row unit design, as each segment can be adjusted according to its specific requirements.

AI summary
An adjustable row cleaner includes a row cleaner assembly that functions to clear material from the ground surface. The adjustable row cleaner includes, in one embodiment, a connector that is in mechanical communication with both a row cleaner frame, to which row cleaner wheels may be pivotally mounted, and a first end of a translator member. The translator member may pivot with respect to the row unit frame and/or row unit sub-frame about a translator member pivot. The position of a translator member second end may be manipulated, thereby adjusting the maximum depth to which the row cleaner wheels penetrate the ground surface. The adjustable row cleaner may be powered or manually adjusted, and the position of the row cleaner wheels may be monitored and automatically adjusted via a control system.
