Adjustable Row Closing Wheels for Elevation Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing row cleaner and closing systems in no-till farming fail to maintain optimal geometry and adjust to changes in land elevation, leading to ineffective residue removal and seed slot closure, especially in varying soil conditions.
Innovation Solution
A two-stage row closing system with adjustable closing wheels and a firming wheel frame, allowing for independent adjustment of toe-in, camber, and angle of closing wheels, and the use of different wheel types to suit soil conditions, ensuring optimal row cleaning and closing action.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing row cleaner and closing systems are used, then the structure is simple and easy to manufacture, but they fail to maintain optimal geometry and adjust to changes in land elevation
Solution Approach 1:
The patent implements a floating frame mechanism that allows the closing wheel assembly to dynamically adjust its vertical position in response to terrain elevation changes. The frame can pivot at the mounting connection to the planter, enabling the closing wheels to rise and fall independently to maintain optimal closing geometry across varying land surfaces.
Solution Approach 2:
The closing system is divided into separate adjustable components including the floating frame assembly, individual closing wheel assemblies, and independent adjustment mechanisms for each wheel. This segmentation allows each component to be optimized and adjusted independently for optimal performance on varying terrain.
2Adaptability or versatility
If fixed row cleaners are used, then the device complexity is low, but they do not follow or track changes in land elevation
Solution Approach 1:
The floating frame closing assembly is designed to automatically track and respond to land elevation changes through its own weight and the natural pivoting action at the mounting connection. The system self-adjusts without requiring external control mechanisms, hydraulic systems, or complex sensing equipment, maintaining operational simplicity while achieving adaptive terrain following.
3Adaptability or versatility
If adjustable and floating row cleaners are used, then they can adapt to terrain changes, but they may not possess the ideal geometry with respect to a planter to provide for optimal row cleaning action
Solution Approach 1:
The patent provides multiple adjustment mechanisms that allow changing of geometric parameters including the angle of the closing wheels relative to the ground, the horizontal and vertical position of the wheels, and the spacing between closing wheels. These adjustable parameters enable optimization of the closing geometry for different soil conditions and terrain types while maintaining the adaptive floating frame capability.
