Semi-mounted Monowheel Plough Adjustable Working Width
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing semi-mounted plows face limitations in size and maintenance due to rigid frame and support wheel constraints, leading to suboptimal working conditions and increased maintenance needs, especially on sloping ground and when encountering obstacles.
Innovation Solution
The plow bodies are linked to the frame via articulations and an integrated control mechanism with straight and curved rods, allowing for adjustable working width and orientation, ensuring optimal use based on soil type and tractor power, and reducing manual debris removal and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the frame is made rigid to provide structural stability, then the structural strength is improved, but the adaptability of working width deteriorates
Solution Approach 1:
The plow body assembly is segmented into independently adjustable units. Each plow body can be adjusted relative to the frame through articulation points, allowing the working width to be modified without changing the rigid frame structure itself. This segmentation enables adaptability while preserving the structural integrity of the frame.
2Force
If the support wheel size is increased to improve ground support, then the ground support capability is improved, but the frame height requirement deteriorates
Solution Approach 1:
The support wheel is positioned within a recess in the frame structure, allowing the wheel to be nested into the frame rather than extending outward. This nesting arrangement enables the support wheel to provide adequate ground support force while maintaining a compact overall frame height that can pass through standard agricultural openings.
3Device complexity
If the plow bodies are rigidly fixed to the frame to simplify structure, then the device complexity is reduced, but the adaptability to different soil types deteriorates
Solution Approach 1:
The plow bodies are connected to the frame through articulation points that allow dynamic adjustment. This enables the plow bodies to be repositioned according to different soil conditions, plowing depth requirements, and field contours, transforming the system from static to dynamically adaptable while maintaining reasonable structural simplicity.
4Device complexity
If the working width is fixed to reduce adjustment mechanisms, then the device complexity is reduced, but the productivity deteriorates
Solution Approach 1:
The plow system is divided into modular plow body units that can be independently adjusted in width. This segmentation allows the working width to be optimized for different field conditions and plot sizes, maximizing productivity by matching the working width to the specific task rather than using a fixed width that may be suboptimal for many conditions.
