Independent Milling Drum Support for Uneven Surface Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for processing horizontal, vertical, or inclined solid surfaces, such as roads and footpaths, face instability and inefficiency due to the inability to independently adjust supporting slides, leading to uneven milling depths and prolonged processing times when forming adjacent furrows.
Innovation Solution
A device with independently adjustable supporting slides, utilizing a lever system that allows each slide to contact different surface levels, ensuring stability and full utilization of the milling drum's capacity by allowing it to maintain a consistent working position across uneven surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the supporting slides are adjusted simultaneously (conventional design), then the device structure is simpler, but the device becomes unstable on uneven surfaces and cannot maintain consistent working depth
Solution Approach 1:
The patent divides the regulating mechanism into separate independent sections for each supporting slide. Each slide has its own regulating means that can be adjusted independently from the others, allowing individual position control while maintaining overall device stability on uneven surfaces.
Solution Approach 2:
The patent introduces adjustable and movable regulating means that allow the supporting slides to be dynamically repositioned during operation. This enables the device to adapt to varying surface conditions and maintain stable contact with the workpiece throughout the processing operation.
2Strength
If the working depth is reduced for tough surfaces, then the device can process harder materials, but the processing time increases due to multiple passes
Solution Approach 1:
The patent uses the independently adjustable supporting slides to perform preliminary positioning and depth setting before the actual milling operation begins. This ensures optimal working depth is established in advance, allowing the device to efficiently remove material in fewer passes while maintaining control on tough surfaces.
Solution Approach 2:
The patent enables continuous effective action of the milling drum by maintaining consistent working depth across multiple passes through independent slide adjustment. This eliminates idle movement and ensures the drum continuously engages the workpiece at the optimal depth, maximizing material removal efficiency.
3Manufacturing precision
If the device positions one slide on the previous furrow to avoid leaving material, then the device can form adjacent furrows without gaps, but the working depth becomes inconsistent
Solution Approach 1:
The patent segments the depth control function so that each supporting slide can be independently positioned and adjusted. This allows one slide to follow the previous furrow while the other maintains consistent depth control, ensuring both furrow continuity and uniform working depth through divided functionality.

AI summary
A device (100) is provided for the demolishing and in particular for milling horizontal, vertical and inclined surfaces or layers suitable for pedestrians and/or vehicles such as for instance asphalt and/or concrete roads. The device comprises rotatable working means (10) rotatably fixed to a main supporting frame (T) which comprises a first supporting element (L) and a second supporting element (F). The device also comprises regulating means adapted to adjust the position of the first supporting element (L) with respect to the main frame (T) independently of the position of the second supporting element (F). The regulating means comprise an arm (R) fixed to the main frame (T) so as to be free to rotate or translate. The first supporting element (L) is rotatably fixed to a portion (H) of the arm (L).
