Soil Preparation Roller with Equal-Mass Working Jackets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Soil preparation machines with soil preparation rollers face challenges in maintaining consistent mass ratios during different working procedures, affecting the preparation result and compaction efficiency due to the change between structured and unstructured working outer sides.
Innovation Solution
A soil preparation roller system with a roller body and a group of working jackets, where at least two working jackets have equal masses, ensuring a consistent overall system mass regardless of the attached working jacket, allowing for adaptable working procedures without impairing the preparation result or wearing down the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different working jackets with different structures (structured vs unstructured) are attached to the roller body, then the adaptability to different working procedures is improved, but the mass ratio of the soil preparation roller system changes, affecting compaction efficiency and preparation quality
Solution Approach 1:
The patent applies parameter changes by ensuring that all working jackets in the group have substantially equal masses, thereby maintaining a constant mass parameter across different working configurations. This allows the system to adapt between structured and unstructured working jackets without changing the overall mass ratio, thus preserving compaction efficiency and preparation quality while maintaining versatility for different working procedures
2Device complexity
If the carrier jacket is used to provide the working outer side, then the structure is simplified, but the ability to adapt to different working procedures (structured vs unstructured) is reduced
Solution Approach 1:
The patent applies segmentation by dividing the working jacket into multiple separate working jackets that can be independently attached to the roller body. Each working jacket can be designed with different structures (structured or unstructured) according to specific working procedure requirements, while all maintain substantially equal masses. This allows the system to adapt to different working procedures without increasing overall structural complexity, as the carrier jacket remains a simple carrier component

AI summary
A soil preparation roller system for a soil preparation machine includes a roller body rotatable around a roller rotational axis having a carrier structure for the rotatable mounting of the roller body and having a carrier jacket supported on the radial outside on the carrier structure, a group of working jackets to be positioned abutting a carrier jacket outer side and providing a working outer side of a soil preparation roller. Each working jacket includes a plurality of working jacket segments to be arranged successively in the circumferential direction completely enclosing the roller body annularly, and the group of working jackets includes at least two working jackets having essentially equal mass to one another.
