Agricultural Implement Side Section Vertical Pivot Axis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural implements with large working widths face challenges in maintaining compliance with maximum permissible transport widths, particularly due to the need for height-adjustable tillage and/or sowing elements, which complicates storage container design and usage with side parts of different working widths.
Innovation Solution
The implement features side parts that can pivot into both working and transport positions, with a vertically oriented pivot axis allowing flexible positioning, and includes a support device that pivots around an upright axis, enabling compact transport while maintaining a wide working width, using adjustable end stops and actuators for precise control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If height-adjustable tillage and/or sowing elements are used, then the implement can adapt to different working conditions, but the hopper volume is reduced and design becomes more complex
Solution Approach 1:
The implement is divided into modular components: a central frame with hopper and multiple interchangeable side panels. Each side panel contains the height-adjustable tillage elements, separating the storage function (hopper) from the adjustable working elements. This allows the hopper to maintain full volume while the side panels provide adaptability through height adjustment mechanisms.
Solution Approach 2:
The side panels with tillage elements are designed to be interchangeable and attach to the central frame. The height-adjustable elements within each side panel can be nested or retracted when not in use, allowing compact storage while maintaining full hopper volume. The modular design enables different side panels to be nested or stored when not attached to the implement.
2Productivity
If side parts are extended to achieve large working width, then working efficiency increases, but transport width exceeds maximum permissible limits
Solution Approach 1:
The side parts are designed with dynamic positioning capability through pivoting mechanisms. During working operations, the side parts extend horizontally to maximize working width. During transport, the side parts can be pivoted upward to a vertical or angled position, reducing the overall transport width to comply with road regulations. This dynamic reconfiguration allows the implement to adapt its dimensions based on operational requirements.
Solution Approach 2:
The side parts utilize vertical space during transport by pivoting upward, transitioning from a horizontal extension (affecting transport width) to a vertical orientation. This dimensional change allows the implement to maintain large working width capabilities while complying with transport width restrictions, effectively using the third dimension (height) to resolve the contradiction.
3Adaptability or versatility
If the same hopper is used with side panels of different working widths, then versatility increases, but positioning and alignment become more difficult
Solution Approach 1:
The central frame and hopper are designed as universal components that can accommodate multiple types of side panels with different working widths. Standardized mounting interfaces, pivot points, and adjustment mechanisms are provided on the central frame to work with various side panel configurations. This universal design allows the same hopper to be used with different side panels while maintaining ease of positioning through consistent attachment procedures.
