Solution Overview
Problem
Existing tillage machines face challenges in arranging distribution equipment for granular and solid materials, particularly with large working widths, and folding mechanisms that risk crushing distribution lines during transport.
Innovation Solution
A soil cultivation machine with a tine field comprising a tine middle section and side sections that can pivot upwards, featuring distribution devices positioned outside the tine field, and a folding mechanism using multiple pivot axes to reduce transport width while maintaining a wide working width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a tine harrow uses a distribution tower to divide material among numerous application points, then distribution efficiency is improved, but the arrangement complexity and space requirements increase significantly
Solution Approach 1:
The distribution tower is repositioned from a central location to the front end of the working width, utilizing the longitudinal dimension of the machine. This spatial reconfiguration allows the tower to serve multiple application points along the working width without requiring complex lateral distribution mechanisms, thereby reducing arrangement complexity while maintaining distribution efficiency.
Solution Approach 2:
The distribution system is segmented into multiple independent distribution lines, each serving a specific section of the working width. This segmentation allows each line to be independently routed and controlled, simplifying the overall arrangement by breaking down the complex task of distributing material across the entire width into manageable sections.
2Adaptability or versatility
If the tine harrow has pivoting tine side sections for transport, then adaptability to transport conditions is improved, but the risk of crushing distribution lines increases
Solution Approach 1:
The distribution lines are extracted from the vulnerable zone between the pivoting tine side sections and repositioned to run along the front end of the working width. This extraction removes the lines from the compression zone created during pivoting operations, protecting them from damage while maintaining the machine's transport adaptability.
Solution Approach 2:
The front end structure serves as an intermediary zone that separates the distribution lines from the pivoting mechanism. By routing lines through this intermediary space at the front end, the design creates a protective buffer zone that prevents direct contact between the lines and the moving pivot parts, thereby protecting line integrity during transport.
3Adaptability or versatility
If the tine harrow is folded to maximum permissible transport width of 3 meters, then compliance with transport regulations is improved, but the working width is reduced
Solution Approach 1:
The machine employs a dynamic configuration where the distribution tower and associated lines are positioned at the front end, allowing the rear sections to be folded compactly for transport. This dynamic arrangement enables the machine to achieve the required 3-meter transport width while maintaining a larger effective working width during operation, as the front-mounted distribution system does not interfere with the folding mechanism.
