Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Towed soil cultivation implements face challenges in maintaining stable depth guidance and traction due to changing pull lines and uneven ground conditions, leading to inconsistent soil tillage and excessive tractor traction requirements.
Innovation Solution
The implementation of depth guide devices with controlled contact pressure, adjustable reconsolidation units, and a draw gear system that distributes weight between the tractor and reconsolidation device, ensuring constant contact pressure and working depth through a controller and adjusting devices, even on uneven terrain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a movable drawbar with hydraulic cylinders is used to transmit implement weight to the tractor, then traction is improved, but the pull line changes constantly on uneven ground causing unstable depth guidance
Solution Approach 1:
The depth guidance function is separated from the traction function by introducing independent depth guide devices with their own support wheels. These devices provide stable depth control through direct ground contact, while the drawbar system handles only the traction function without interfering with depth stability.
Solution Approach 2:
Depth guide devices act as intermediary elements between the implement frame and the ground. They provide a stable reference point for depth control by directly contacting the ground surface, mediating the interaction between the movable implement and the variable terrain to maintain consistent working depth.
2Stability of the object's composition
If a rigid draw gear arrangement is used to achieve constant pull line run, then depth guidance stability is improved, but the working depth deviates from setpoint on uneven ground
Solution Approach 1:
The depth guide devices are designed with movable support wheels that can dynamically adapt to uneven ground surfaces. The support wheels follow the ground contour while maintaining controlled contact pressure, allowing the implement to maintain precise working depth despite terrain variations.
Solution Approach 2:
The contact pressure of the depth guide devices is controlled as a variable parameter. By adjusting and maintaining optimal contact pressure, the system adapts to different ground conditions while preserving depth guidance accuracy, transforming a static parameter into a dynamically optimized variable.
3Manufacturing precision
If depth guide devices with controlled contact pressure are implemented, then working depth precision is improved, but device complexity increases
Solution Approach 1:
The depth guide devices utilize their own weight and controlled contact pressure to maintain depth guidance without requiring external active control systems. The support wheels automatically adapt to ground variations through their mechanical design, providing self-regulating depth control that minimizes the need for complex electronic or hydraulic control systems.
