Rotating Support Row Unit for Field Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional agricultural implements require time-consuming and labor-intensive changes to row units for adapting to different soil conditions, as each unit must be individually modified and parts stored, limiting efficient fertilizer delivery and crop yield.
Innovation Solution
The implementation of rotating supports on row units that can be quickly reconfigured by rotating and re-locking different ground-engaging tools, allowing for rapid adaptation to various field conditions without the need for tools or extensive labor, using locking pins and actuators for controlled tool positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional row units are used with fixed ground-engaging tools, then the structure is simple and reliable, but the adaptability to different soil conditions is poor and tool changes are time-consuming
Solution Approach 1:
The patent applies the dynamics principle by making the ground-engaging tools rotatable relative to the row unit frame. Each tool can be rotated into different positions to engage with the ground, allowing the same row unit to adapt to various soil conditions without physical replacement of components. This dynamic reconfiguration resolves the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The patent implements universality by designing a single row unit with multiple ground-engaging tools that can be selectively positioned. The rotating mechanism allows one tool assembly to perform multiple functions by presenting different tools to the ground surface, eliminating the need for multiple specialized row units and reducing overall system complexity while improving adaptability.
2Adaptability or versatility
If multiple ground-engaging tools are carried on each row unit for adaptability, then the versatility improves, but the device complexity and labor required for reconfiguration increases
Solution Approach 1:
The rotating support mechanism enables dynamic reconfiguration of ground-engaging tools without manual disassembly or complex adjustment procedures. Operators can simply rotate the tool assembly to the desired position and engage it with the ground, transforming a potentially complex multi-tool system into an easily operable configuration change process.
3Adaptability or versatility
If row units are disassembled and reconfigured for different field conditions, then the adaptability improves, but the time required for reconfiguration increases
Solution Approach 1:
The patent eliminates time-consuming disassembly and reassembly operations by implementing a rotatable tool support mechanism. Ground-engaging tools can be reconfigured in-place through simple rotation movements, reducing reconfiguration time from potentially lengthy manual processes to quick positional adjustments that can be performed during field operations or between passes.
Solution Approach 2:
Multiple ground-engaging tools are pre-mounted on the rotating support assembly in predetermined positions. This preliminary arrangement of tools allows operators to simply rotate to the appropriate tool for current conditions rather than assembling tools during field operations, significantly reducing reconfiguration time while maintaining full adaptability.

AI summary
An agricultural implement includes a frame carrying a toolbar, and row units coupled to the toolbar. Each row unit includes a tool support and a rotating support coupled to the tool support and configured to rotate about an axis of rotation. Ground-engaging tools are carried by the rotating support and extending outward from the axis of rotation. Rotation of the rotating support about the axis of rotation moves the ground-engaging tools around the rotating support to change which of the ground-engaging tools interacts with the ground. A method of adjusting the agricultural implement includes disengaging the row units from a ground surface, rotating at least one rotating support about a corresponding axis of rotation to move the ground-engaging tools around the rotating support, and re-engaging the row units with the ground surface.
