Couplable Sweeper-Blower Pivoting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing snow clearing vehicles face difficulties in easily pivoting their sweeper-blower arrangements between working and transport positions, requiring manual intervention to establish or remove blow-air connections, which complicates operation and increases the risk of disconnection during vehicle movement.
Innovation Solution
The sweeper-blower arrangement is designed to pivot between working and transport positions using a coupling device that automatically connects and disconnects the blow-air device and hollow body through controlled pivoting movements, eliminating the need for manual intervention and ensuring reliable blow-air connections during operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the hollow body and blow-air device remain connected during the entire pivoting movement, then the blow-air connection is maintained, but the construction becomes complex and difficult to pivot
Solution Approach 1:
The hollow body is divided into multiple segments that can pivot relative to each other. The first hollow body segment is connected to the supporting frame, while the second hollow body segment is connected to the blow-air device. This segmentation allows the sweeper-blower arrangement to pivot between working and transport positions without requiring complex support structures to maintain the blow-air connection throughout the entire movement range.
2Reliability
If manual intervention is required to establish or remove blow-air connections, then connection reliability can be ensured, but operation complexity increases and driver convenience decreases
Solution Approach 1:
The system automatically establishes and removes blow-air connections through the pivoting movement itself. When the sweeper-blower arrangement is pivoted to the working position, the hollow body segments automatically align and connect the blow-air pathway. When pivoted to the transport position, the connection automatically disconnects. This eliminates the need for manual intervention by the driver while maintaining reliable connections during operation.
3Loss of energy
If the sweeper-blower arrangement is pivoted to transport position for high-speed movement, then energy efficiency improves, but the blow-air connection may be disrupted without automatic coupling
Solution Approach 1:
The hollow body is designed with dynamic characteristics that allow it to automatically couple and decouple based on the pivoting position. The first hollow body segment remains relatively stationary while the second hollow body segment pivots with the blow-air device. This dynamic design ensures that the blow-air connection is automatically established when needed and automatically removed during transport, preventing energy waste while maintaining connection stability during operation.

AI summary
A clearing vehicle comprises a supporting frame (3) and a sweeper-blower arrangement (4), which is adjustably pivotable around a vertical axis (5) which runs through the clearing vehicle with respect to the supporting frame (3) and comprises a blow-air device (8). Furthermore, a blower (6) is arranged at the supporting frame (3), wherein blow-air is conducted from the blower (6) through the hollow body (7) to the blow-air device (8). The hollow body (7) and the blow-air device (8) are brought in blow-air connection by a first pivoting movement from a transport position to a working position. The blow-air connection between the hollow body (7) and the blow-air device (8) is removed by a second pivoting movement from the working position to the transport position.
