Multi-Purpose Road Sweeper with Hydraulic Brush and Scrapper
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current road construction equipment lacks a single, effective solution for efficiently removing both large overburden and small waste materials during road construction, as existing sweepers are limited in their ability to handle varying debris sizes and terrain.
Innovation Solution
A self-propelled, multi-purpose surface cleaning machine equipped with a rotating sweeper brush and scrapper blade assembly, featuring hydraulic cylinders for adjustable positioning, allowing for efficient sweeping and scraping of road surfaces in both forward and reverse directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-purpose sweeper or scrapper is used, then the equipment can effectively handle its designated task, but it cannot efficiently remove both large overburden and small waste materials simultaneously
Solution Approach 1:
The patent combines a scrapper blade assembly and a sweeper brush assembly into a single integrated road construction machine. The scrapper blade is positioned at the rear to remove large overburden, while the sweeper brush is positioned at the front to collect smaller waste materials. Both assemblies are mounted on the same vehicle chassis and can be operated simultaneously, allowing the machine to handle both large and small debris in one pass without requiring separate equipment.
Solution Approach 2:
The road construction machine is designed with multi-functional capabilities by integrating both scraping and sweeping functions into a single vehicle. The hydraulic system provides universal control over both the scrapper blade and sweeper brush, allowing the operator to perform multiple cleaning tasks with one piece of equipment rather than requiring separate specialized machines for different debris types.
2Productivity
If street sweepers are used to clean road surfaces, then small waste materials can be removed, but they cannot effectively move larger waste or overburden
Solution Approach 1:
The patent merges the functions of street sweepers (for small waste) and scrapers (for large overburden) into a single integrated machine. The front-mounted sweeper brush handles smaller debris while the rear-mounted scrapper blade manages larger materials, enabling the vehicle to perform both cleaning functions simultaneously and significantly improving overall productivity compared to using separate equipment.
3Adaptability or versatility
If industrial sweepers are used for road construction, then they can clean smaller waste, but they lack the capability to remove overburden during construction
Solution Approach 1:
The road construction machine is designed with universal applicability for various construction scenarios by integrating both scrapper and sweeper functions. This multi-functional design allows the same equipment to be used throughout the construction process for different types of debris removal, from initial overburden clearance to final surface cleaning, reducing the need for multiple specialized vehicles.
4Productivity
If scraping equipment is used to remove overburden, then large waste can be moved, but smaller waste materials remain on the surface
Solution Approach 1:
The patent combines scraping and sweeping functions in a single integrated system where the scrapper blade removes large overburden and the sweeper brush simultaneously or sequentially collects smaller waste materials. This combination ensures that both large and small debris are effectively removed from the road surface, eliminating the need for separate follow-up cleaning operations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables comprehensive cleaning of road surfaces by effectively removing overburden and waste materials, improving operational efficiency and adaptability to different debris sizes and terrain variations.
Implementation Method 1
An electric or hydraulic motor drives the rotating brush or brushes along the surface of the area being cleaned, sweeping material into a bucket
Implementation Method 2
at least one hydraulic cylinder attached between the sweeper brush frame and the vehicle frame for raising and lowering the sweeper brush responsive to actuation of the lift cylinder
