Walking Axle Equalizer Assembly for Consistent Seed Depth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural seed planters face challenges in maintaining consistent seed depth and preventing damage to planter components when operating in rough field conditions with moist or wet soil, and in efficiently distributing liquid fertilizer without interfering with seed placement.
Innovation Solution
The agricultural planter incorporates a walking axle assembly with a lever arm, a rotatable furrow-opening disc, and a first rotatable furrow-closing wheel, which allows the fertilizer furrow opener disc and closing wheel to oscillate over field obstructions, maintaining consistent seed depth and preventing damage to planter components. Additionally, the planter's design enables the fertilizer distribution system to operate effectively without soil buildup on the gage wheels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
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 soil accumulates on the gage wheels causing the planter to run too shallow
Solution Approach 1:
The planter is divided into separate functional modules: the fertilizer depositing equipment is separated from the main planter body and mounted on the trailing arm assembly, allowing independent operation of fertilizer deposition and seed planting functions, preventing soil accumulation on gage wheels while maintaining consistent seed depth
Solution Approach 2:
The trailing arm assembly acts as an intermediary mechanism that allows the fertilizer furrow opener disc and closing wheel to oscillate over field obstructions independently, maintaining proper seed depth while the fertilizer equipment operates separately without causing soil buildup on the gage wheels
2Adaptability or versatility
If fertilizer depositing equipment is located on the front end of the planter, then liquid fertilizer can be provided, but the planter cannot be folded without removing the fertilizer depositing equipment
Solution Approach 1:
The fertilizer depositing equipment is mounted on the pivotable trailing arm assembly that can dynamically adjust its position and fold along with the planter, enabling the planter to be folded for transport without removing the fertilizer depositing equipment while maintaining operational flexibility in the field
3Adaptability or versatility
If the planter operates in rough field conditions with substantial deviation in field surface, then it can traverse difficult terrain, but seed depth becomes inconsistent and planter components may be damaged
Solution Approach 1:
The trailing arm assembly with pivotable mounting allows the fertilizer furrow opener disc and closing wheel to dynamically oscillate and adapt to field obstructions and surface deviations, maintaining consistent seed depth while traversing rough terrain without damaging planter components
Solution Approach 2:
The pivotable trailing arm assembly changes the operational parameters of the fertilizer equipment by allowing angular adjustment and oscillation, enabling the planter to accommodate variations in field surface conditions while maintaining proper seed placement depth

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.
