Slipform Paver Auger Cleaning via Self-Service Spraying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slipform pavers face challenges in effectively cleaning their conveying devices, particularly auger conveyors, which prevents thorough cleaning of all areas.
Innovation Solution
Incorporating a cleaning device with a guiding device and adjustable spraying devices, driven independently of the motor drive system, to ensure comprehensive cleaning of the conveying device, including the use of high-pressure nozzles and a controller for automated operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a cleaning device is added to the conveying device, then cleaning quality is improved, but device complexity increases
Solution Approach 1:
The cleaning device is integrated onto the conveying device itself, allowing the conveying device to clean itself. The cleaning device moves along with the conveying device and can access all areas including hard-to-reach spots, eliminating the need for separate external cleaning equipment while improving cleaning quality.
Solution Approach 2:
The cleaning device is designed to perform multiple functions: it can clean different areas of the conveying device (auger, hopper, etc.), and can be moved to various positions along the conveying device. This multi-functional design improves cleaning quality without requiring multiple separate cleaning systems.
2Area of stationary object
If the cleaning device is made movable along the conveying device, then cleaning coverage is improved, but device complexity increases
Solution Approach 1:
The cleaning device is designed to be movable along the conveying device rather than fixed. It can be positioned at different locations and moved to access all areas of the conveying device including the auger and hopper regions, thereby improving cleaning coverage while maintaining manageable complexity through standardized movement mechanisms.
