Agricultural Soil Roller with Segmented Discs for Uniform Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural devices with wider operating widths face a structural deficiency where gaps between rollers lead to uneven soil processing, resulting in poor crop growth and economic losses due to irregular disc spacing along the operating width.
Innovation Solution
The design features two sets of working rollers with a central and wing structure, where the left and right sets have different numbers of discs and lengths, with additional discs placed between attachments to maintain uniform disc spacing, ensuring even soil processing across the width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the agricultural device uses a single continuous working roller, then the soil is evenly processed along the whole width, but the device cannot be folded for transport on roads
Solution Approach 1:
The single continuous working roller is divided into multiple separate rollers (front roller and rear roller) that can be independently positioned. This segmentation allows the device to maintain even soil processing coverage while enabling the wings to be folded for transport, as each roller can be independently mounted on the respective wings or central part
2Adaptability or versatility
If two rear rollers are used on folded wings, then the device can be transported on roads, but gaps appear between rollers causing uneven soil processing
Solution Approach 1:
The front and rear rollers are equipped with different numbers of discs tailored to their specific positions and functions. The front roller has discs corresponding to working units for soil processing, while the rear roller has discs specifically for leveling the piled-up soil. This local differentiation ensures that each roller performs its specific function effectively, maintaining even soil processing across the entire width while allowing the structure to be folded for transport
3Reliability
If discs are arranged with regular distances on a single roller, then even soil processing is achieved, but the device structure cannot accommodate folding wings
Solution Approach 1:
The disc arrangement is segmented between front and rear rollers rather than attempting to maintain regular spacing on a single continuous roller. The front roller discs correspond to working units for processing, while rear roller discs are positioned for leveling. This segmentation resolves the conflict between maintaining regular disc spacing for even processing and accommodating the folded wing structure for transport
Solution Approach 2:
The solution moves from a single-dimensional continuous roller to a two-dimensional arrangement with front and rear rollers at different positions. This dimensional change allows discs to be distributed across multiple rollers with appropriate spacing, achieving even soil processing while accommodating the folded structure of the wings for transport

AI summary
An agricultural device for soil processing with two sets of working rollers comprises a supporting frame, which comprises a central part, a left wing and a right wing. The left and right wings are rotatably attached to the central part. At least two rows of working units are attached to the supporting frame. The working units are arranged in regular distances in every row. A left set of rollers is attached to the left wing and a right set of rollers is attached to the right wing. The sets of rollers are divided into front rollers and rear rollers and provided with attachments and discs. The discs on the sets are located between these attachments. The number of discs of rear rollers differs exactly by one disc from the number of discs of front rollers. The distances between individual discs are the same along the whole width of the agricultural device. The discs of front rollers are located in the same plane as the working units.
