Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing row cleaner and closing assemblies in no-till farming systems lack adjustable geometry and optimal engagement with varying terrain, leading to inefficient soil interaction and closure in different soil conditions.
Innovation Solution
A closing wheel frame assembly with a lever-adjustable axle system that allows for manual adjustment of the closing wheel's angle and orientation, enabling optimal engagement with the soil through adjustable toe and camber settings, accommodating changes in soil height and condition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed row cleaners and closing assemblies are used, then the structure is simple and easy to manufacture, but they cannot follow terrain changes or maintain optimal geometry with varying soil conditions
Solution Approach 1:
The patent implements a floating closing assembly that can dynamically adjust its position and orientation in response to terrain variations. The assembly includes a floating frame with rollers that allow the closing wheels to maintain optimal contact with the soil surface regardless of elevation changes, transforming a static structure into a dynamic, terrain-adaptive system.
Solution Approach 2:
The closing assembly is divided into modular components including individual closing wheels, floating frame sections, and adjustable linkages. This segmentation allows each component to independently respond to local terrain conditions while maintaining overall system functionality, enabling adaptability without requiring complete redesign of the entire assembly.
2Adaptability or versatility
If adjustable row cleaners are used, then terrain following capability is improved, but they do not provide ideal geometry for optimal row cleaning action
Solution Approach 1:
The closing assembly incorporates self-adjusting mechanisms where the floating frame and roller linkages automatically position the closing wheels at optimal angles relative to the soil surface. The system uses the terrain itself as the adjustment input, eliminating the need for manual geometric adjustments while maintaining ideal cleaning action across varying conditions.
Solution Approach 2:
The patent employs adjustable linkages that modify the geometric parameters of the closing assembly, specifically the angle and position of closing wheels relative to the frame. These parameter changes are achieved through mechanical linkages that respond to terrain variations, providing optimal geometry without complex manual adjustment mechanisms.
3Reliability
If existing row closing assemblies are used, then the basic closing function is performed, but they do not maintain ideal desired geometry for closing wheels over terrain
Solution Approach 1:
The floating closing assembly maintains reliable performance by dynamically adapting its geometry to terrain variations. The rollers and linkages continuously adjust the position of closing wheels to maintain optimal contact angles, ensuring consistent closing action whether the terrain is flat or uneven, thereby achieving both reliability and terrain accommodation.
4Adaptability or versatility
If closing wheels have fixed engagement angle, then the structure is simple, but they cannot accommodate changes in soil height and condition
Solution Approach 1:
The patent implements adjustable linkages that modify the engagement angle parameter of closing wheels based on soil conditions and terrain elevation. These linkages provide granular adjustment capability, allowing operators to fine-tune the wheel angle for different soil types and heights without requiring complex mechanical adjustment mechanisms.

AI summary
A closing wheel frame assembly comprising a closing wheel frame, a closing wheel assembly, and a lever arm adjustment assembly. A retaining pin secures a lever arm in a desired position to set an angle or orientation of the closing wheel assembly relative to the frame, seed furrow (trench or trough), or soil surface. Operation of the lever arm changes the angle or orientation of the closing wheel assembly relative to the frame, seed furrow (trench or trough), or soil surface.
