Depth-Gauge Leveling Wheel With Stubble Sweeper and Quick Tire Change
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current agricultural planting machines face issues with the leveling wheel, including blockages due to debris and uneven terrain, time-consuming maintenance tasks such as tire replacement and bearing replacement, and inefficient lubrication, which affect planting efficiency and downtime.
Innovation Solution
A new leveling wheel design featuring curved side blades to prevent debris entry and a quick-change ring for easy tire replacement, along with a simplified bearing replacement system that allows maintenance without removing the wheel, and improved lubrication access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the leveling wheel operates close to the planting disc to maintain furrow depth, then planting precision is improved, but debris and stubble accumulate between the wheel and disc causing blockages
Solution Approach 1:
The invention extracts and removes accumulated debris and stubble from the space between the leveling wheel and planting disc using a dedicated cleaning element (brush or scraper) that actively clears contaminants, preventing blockages while maintaining the close operational positioning of the wheel
Solution Approach 2:
The cleaning element acts as an intermediary between the leveling wheel and planting disc, facilitating continuous operation by removing debris that would otherwise cause blockages, thus enabling the system to maintain both close positioning and reliable operation
2Manufacturing precision
If the leveling wheel maintains close contact with the ground for accurate depth control, then planting depth precision is improved, but the wheel requires frequent cleaning and greasing increasing maintenance time
Solution Approach 1:
The leveling wheel system performs self-service through the automated cleaning element that continuously removes debris during operation, and self-lubrication features that reduce the frequency of manual greasing, significantly decreasing maintenance time while maintaining precise depth control
Solution Approach 2:
The cleaning element performs preliminary action by proactively removing debris before it accumulates to blocking levels, and lubrication features apply grease in advance to prevent friction and wear, reducing the need for frequent maintenance interruptions
3Object-affected harmful factors
If the tire is made wider to avoid soil compaction, then soil health is improved, but tire replacement becomes more difficult and time-consuming
Solution Approach 1:
The wheel assembly is segmented into modular components including the tire, rim, and mounting structure, allowing the tire to be independently removed and replaced without dismantling the entire wheel assembly, making wider tire replacement easier and more efficient
4Strength
If the leveling wheel is equipped with a fixed tire and bearing assembly, then structural integrity is improved, but maintenance requires complete disassembly of the mounting arm and wheel assembly
Solution Approach 1:
The wheel assembly is divided into separable modules with the tire and bearing components accessible from the outside, allowing maintenance personnel to service individual components without disassembling the entire mounting arm and wheel assembly, thus maintaining structural integrity while simplifying maintenance procedures

AI summary
A groove depth-leveling wheel used in planting groups defines the depth of the furrow opened by the planting disc for uniform planting. The wheel has blades on its outer side to prevent reeds, stubble, straws etc. from sticking between this wheel and the planting disc and blocking the wheel or the planting disc itself.
