Adjustable Planter Frame Assembly for Variable Row Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional agricultural machines lack the ability to adjust row spacing and fore-aft offset between row units based on crop type or growing conditions, leading to inefficient fuel consumption, field compaction, and inability to adapt to different planting needs.
Innovation Solution
An adjustable frame design with movable frame members and drive mechanisms, such as electric actuators or hydraulic systems, allows for dynamic adjustment of row unit spacing and fore-aft positioning, enabling flexible planting configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional fixed frame design is used, then device complexity is low, but adaptability to different crop types and row spacing requirements is poor
Solution Approach 1:
The frame members are designed to be movable rather than fixed, allowing dynamic adjustment of row spacing and fore-aft offset. The drive mechanisms enable the frame to adapt its configuration based on crop type and growing conditions, transforming a static structure into a dynamic system that can change its operational parameters.
Solution Approach 2:
The frame is divided into multiple independent movable frame members that can be adjusted relative to each other. This segmentation allows individual adjustment of different sections of the frame to achieve desired row spacing configurations without requiring complete redesign of the entire frame structure.
2Productivity
If fixed row spacing is used, then device complexity is low, but productivity is reduced due to inability to optimize for different crop types
Solution Approach 1:
The system enables change of critical parameters including row spacing and fore-aft offset between adjacent row units. By allowing these parameters to be adjusted based on crop type and growing conditions, the system optimizes planting efficiency and reduces fuel consumption without requiring complete system redesign.
3Productivity
If narrower row spacing is used, then productivity increases, but field residue management becomes more difficult due to obstruction and plugging
Solution Approach 1:
The frame members can dynamically adjust their positions to change fore-aft offset between adjacent row units. This dynamic adjustment allows the system to increase spacing between row units in narrower configurations, creating adequate space for field residue to pass through without obstruction while maintaining high planting density.

AI summary
An adjustable frame assembly of a planter includes a main frame, a first frame member movably coupled to the main frame, and a drive mechanism operably coupled between the main frame and the first frame member for moving the first frame member along the first axis relative to the main frame. The first frame member is laterally movable along a first axis which is perpendicular to a direction of travel of the planter. The frame assembly also includes a first arm having a first end and a second end, the first end being coupled to the main frame and the second end being coupled to a first row unit. A second arm is provided having a first end and a second end, where the first end is coupled to the first frame member and the second end is coupled to the first row unit.
