Arc-Adjustable Cylindrical Brush for Rear Roller Debris Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices for turfed areas fail to effectively collect debris around the rear roller, leading to accumulation and reduced efficiency, as debris escapes the cylindrical brush and accumulates on the roller, disrupting the cleaning process.
Innovation Solution
A cleaning device with a cylindrical brush that rotates in the opposite direction to the rear roller, adjustable in height along an arc path centered on the roller's longitudinal axis, ensuring continuous cleaning and optimal debris collection by maintaining constant working height and contact with the roller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a scraping tool is used to clean the rear roller, then debris can be removed from the roller, but the detached debris falls behind the roller and leaves residue on the ground
Solution Approach 1:
The cylindrical brush acts as an intermediary element between the rear roller and the ground. It contacts the roller to remove debris while simultaneously directing the debris forward into the collection container, preventing it from falling behind and creating residue on the ground
Solution Approach 2:
The cylindrical brush extracts debris from the rear roller surface through contact and friction. By rotating in the opposite direction to the roller, it effectively removes accumulated debris and transfers it to the collection container rather than allowing it to drop behind
2Device complexity
If the cylindrical brush height is fixed, then the structure is simple, but debris accumulates around the roller as the roller diameter increases, reducing cleaning efficiency
Solution Approach 1:
The cylindrical brush height adjustment mechanism transforms a static structure into a dynamic one. The brush can be adjusted vertically along an arc path centered on the roller axis, allowing the operating height to be adapted as the roller diameter changes due to debris accumulation, thereby maintaining continuous cleaning effectiveness
Solution Approach 2:
The system allows changing the vertical position parameter of the cylindrical brush. By adjusting the brush height along the arc path, the device adapts to varying roller diameters and maintains optimal contact pressure for debris removal, preventing accumulation around the roller
3Device complexity
If the cylindrical brush rotates in the same direction as the rear roller, then the structure is simpler, but debris cannot be effectively picked up and projected into the recovery bin
Solution Approach 1:
The cylindrical brush rotates in the opposite direction to the rear roller, creating a counter-rotating system. This inversion of rotation direction generates the necessary friction and relative motion to effectively pick up debris from the roller surface and project it forward into the recovery bin, rather than simply transporting it along with the roller rotation
Applied Scientific Principles

Function Achieved in This Case
The device ensures nearly complete debris collection and prevents residue from accumulating on the rear roller, maintaining efficient debris pickup and transfer to the recovery bin, while allowing easy adjustment of the brush height for varying grass heights.
Implementation Method 1
The cylindrical brush 2 is driven by a hydraulic, electric or other motor, not shown, driving the brush in the opposite direction to the rotation of the roller 1
Implementation Method 2
the cylindrical brush 2 allows collection of debris D present on the turfed area in front of the brush and their projection into a rear recovery or collecting bin 3

AI summary
The invention relates to a cleaning device particularly for grassed areas. The cleaning device includes a cylindrical brush in contact with a rear roller to clean the roller. The brush can be adjusted to a working height relative to the chassis of the device, along an arcuate path having a center situated on the longitudinal axis of the roller.
