Adjustable Rotary Brush for Paving Machine Spillage Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paving machines face issues with spillage of paving material during transfer, leading to uneven asphalt mats and disruptions in the paving process, as prior solutions like strike-off plows lack adjustability and effectiveness across varying machine designs and material sources.
Innovation Solution
A rotary brush assembly with adjustable mounting arms and blades is integrated into the paving machine, allowing for the removal of spillage by engaging and sweeping it out of the path of the ground engaging mechanisms, featuring a motor-driven shaft with radially extending blades that can be positioned and angled for optimal debris removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If strike-off plows are installed to remove spillage, then spillage removal capability is improved, but range of motion and adjustability remain limited
Solution Approach 1:
The rotary brush assembly replaces the static strike-off plow with a dynamic rotating system. The brush assembly includes a rotating hub with multiple bristles that can spin to actively sweep spillage away from the paving path, providing both removal capability and adaptive motion through rotation control
Solution Approach 2:
The brush assembly is divided into multiple independent bristles mounted on a rotating hub, allowing each bristle to independently contact and sweep spillage while the entire assembly can be positioned at various angles and locations to adapt to different spillage scenarios
2Object-affected harmful factors
If flaps or shields are used in hopper systems to prevent spillage, then spillage prevention is improved, but adaptability to varying material sources and velocities is reduced
Solution Approach 1:
The rotary brush assembly acts as an intermediary device positioned between the hopper discharge area and the paving path. It actively intercepts and redirects spillage that escapes the hopper system, providing a secondary protection mechanism that works alongside flaps and shields to handle materials from various sources and velocities
3Object-affected harmful factors
If manual removal of spillage is performed, then spillage removal effectiveness is improved, but labor requirements and time consumption increase
Solution Approach 1:
The rotary brush assembly is self-operating once installed on the paving machine. It automatically rotates and sweeps spillage away from the paving path without requiring manual intervention, eliminating the need for workers to stop and manually remove spillage while maintaining continuous operation
