Seed Planter Equalizer Assembly for Rough Field Depth Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural seed planters face challenges in maintaining consistent seed depth and preventing damage when operating in rough field conditions with moist or wet soil, and they often require removal of fertilizer equipment for folding, which is inconvenient and can lead to soil accumulation on gage wheels.
Innovation Solution
The implementation of a walking axle assembly with a pivotally coupled lever arm, a fertilizer furrow opener disc, and a trailing furrow closer wheel, allowing the disc and wheel to oscillate over field obstructions without impacting seed depth and enabling the planter to fold without removing fertilizer equipment, thus preventing soil accumulation on gage wheels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If fertilizer depositing equipment is located on the front or leading end of the planter, then liquid fertilizer can be deposited in the fertilizer furrow, but moist or wet soil accumulates on the gage wheels causing the planter to run too shallow
Solution Approach 1:
The planter is divided into functionally independent segments: the main planter body with gage wheels for seed depth control, and a separate foldable trailing section carrying the fertilizer depositing equipment. This segmentation prevents soil accumulation on gage wheels while maintaining fertilizer deposition capability.
Solution Approach 2:
The fertilizer depositing equipment is mounted on a foldable trailing section that can be dynamically positioned during transport and operation. This dynamic configuration allows the equipment to be raised or lowered as needed, preventing soil accumulation issues while maintaining operational flexibility.
2Ease of manufacture
If fertilizer depositing equipment is located on the front or leading end of the planter, then liquid fertilizer can be deposited, but the planter cannot be folded without removing the fertilizer depositing equipment
Solution Approach 1:
The fertilizer depositing equipment is separated from the main planter body into a distinct foldable trailing section. This allows the main body to be folded for transport while the fertilizer equipment remains attached to the foldable section, eliminating the need to remove equipment for folding.
Solution Approach 2:
The trailing section with fertilizer equipment is designed to be foldable and movable, allowing it to be positioned during transport and unfolded during operation. This dynamic design provides adaptability for both folded storage and operational states.
3Adaptability or versatility
If the planter traverses fields with substantial deviation in field surface and obstructions, then it can handle rough field conditions, but seed depth becomes inconsistent and planter components are damaged
Solution Approach 1:
The trailing section with fertilizer equipment is designed to be movable and adaptable to field conditions. The foldable design allows the section to adjust to surface variations and obstructions, maintaining seed depth consistency while handling rough terrain.
4Adaptability or versatility
If the planter traverses fields with substantial deviation in field surface and obstructions, then it can handle rough field conditions, but planter components are damaged
Solution Approach 1:
The foldable trailing section is designed to be movable and adaptable to field conditions. This dynamic design allows the section to adjust to surface variations and obstructions, reducing impact forces and preventing damage to planter components while maintaining operational capability in rough terrain.

AI summary
A bracket for use with an agriculture planter including a trailing arm frame defining a pivot point thereon may include an arm bracket assembly with first and second arms. Each arm may extend from a middle portion of the bracket. First and second implements may be rotatably mounted on mounting ends of two of the arms. The middle portion of the bracket may be pivotally coupled to the trailing arm frame at the pivot point.
