Rotary Brush Turf Sweeper With Remote Height Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing turf sweeping devices cause damage to golf course turf due to sudden brush deployment, height adjustment complexities, and inconsistent brush alignment, leading to uneven turf maintenance and potential damage.
Innovation Solution
A rotary brush turf sweeper with pivotably attached brush carriages and an electronic actuator for remote height adjustment, ensuring constant rotational motion and precise height control, minimizing physical stress on the turf and allowing for efficient debris removal and aeration hole filling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If transport wheels are deployed to elevate drive wheels and frame for towing, then the sweeping apparatus can be easily transported, but the brushes cannot be rotated during transport and may cause turf damage upon deployment
Solution Approach 1:
The drive wheels are designed to automatically rotate the brushes before they contact the turf during deployment. This preliminary rotational action ensures the brushes are already moving when they engage with the turf, preventing sudden shock and potential turf damage that would occur with static brush deployment
2Ease of operation
If complex adjusting apparatus with infinitely adjustable members is used at all four corners, then brush height can be adjusted, but it is difficult to achieve precise and consistent height settings at all corners
Solution Approach 1:
The adjustment mechanism at each corner is linked to the others through the frame structure, so that when one corner is adjusted, the other corners automatically adjust to maintain parallel alignment. This merging of adjustment functions ensures all four brush corners remain at consistent heights without requiring complex independent adjustment at each corner
Solution Approach 2:
All four corners of the frame are equipped with identical adjustment mechanisms, ensuring uniformity in the adjustment process. This homogeneity allows for consistent height settings across all corners, eliminating the guesswork and measurement issues associated with mixed or asymmetric adjustment systems
3Productivity
If brushes are deployed in static position to contact turf, then the sweeping apparatus can start working, but the sudden shock can cause the chain or belt to disengage
Solution Approach 1:
The drive wheels begin rotating the brushes before the brushes contact the turf. This preliminary rotation ensures the brushes are already in motion when they engage with the turf surface, preventing sudden shock loads that would cause the chain or belt to disengage and maintain reliable drive mechanism operation

AI summary
A rotary brush turf sweeper includes a frame with a first and second brush carriage supporting a first and second rotary brush. The brush carriages include a first and second carriage bar extending lengthwise along the first and second rotary brush. The brush carriages pivotably attach to the frame by a mounting point on opposing ends of the first brush carriage, allowing the brush carriages to rotate about the attachment point. A brush height adjustment mechanism joins the carriage bars with an electronic actuator. The electronic actuator may be remotely operated to adjust the height of the rotary brushes from a work surface and elevate them so as not to touch the work surface. A first and second drive mechanism transfers rotational force from a pair of drive wheels, so that the rotary brushes always rotate as the device is towed by a vehicle.
