Cultivator Quick Adjustment Assemblies for Field Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cultivators are difficult to adjust, requiring time and labor to accommodate changing field conditions, and are often misused by inexperienced operators, leading to ineffective weed control.
Innovation Solution
A cultivator design with quick adjustment assemblies for incremental adjustments to earth working tool angle, depth, and gauge wheel depth, allowing for tool-free configuration and operation, including tandem gauge wheels and fenders for crop protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cultivators are used, then weed control function is provided, but adjustment complexity increases and operation time increases
Solution Approach 1:
The cultivator employs dynamic adjustment mechanisms that allow the earth working tools and gauge wheels to be quickly repositioned during field operations. The adjustable components enable operators to modify tool depth, angle, and gauge wheel position on-the-fly to adapt to varying field conditions, resolving the contradiction between maintaining reliable weed control and reducing adjustment complexity.
Solution Approach 2:
The system implements multiple adjustable parameters including earth working tool depth, tool angle relative to the ground, and gauge wheel depth. These parameter changes allow the cultivator to maintain optimal performance across different field conditions while simplifying the adjustment process through standardized adjustment mechanisms.
2Reliability
If conventional cultivators are used, then weed control function is provided, but adjustment time increases
Solution Approach 1:
The cultivator features pre-configured adjustment positions and pre-set parameters for common field conditions. Operators can quickly select from predetermined settings rather than making custom adjustments each time, significantly reducing adjustment time while maintaining reliable weed control effectiveness.
Solution Approach 2:
The dynamic adjustment mechanisms allow operators to rapidly reconfigure the cultivator between rows or field sections. The quick-adjust features enable timely adaptation to changing conditions without significant time loss, maintaining both effectiveness and efficiency.
3Reliability
If conventional cultivators are used, then weed control function is provided, but ease of operation decreases
Solution Approach 1:
The cultivator incorporates self-adjusting features and intuitive control mechanisms that reduce the skill level required for proper operation. The design allows operators to make effective adjustments without extensive training, improving ease of operation while maintaining reliable weed control through standardized adjustment procedures and visual indicators.

AI summary
A cultivator includes at least one cultivator row unit, each of the at least one cultivator row unit having a support assembly for securing the cultivator row unit to a tool bar, a shank, an earth working tool operatively connected to the shank, and at least one assembly for providing discrete incremental adjustment for at least one of (a) an angle of the earth working tool, (b) a depth of the earth working tool, and (c) a gauge wheel depth.
