Earth Working Roller With Grid Impact Bars
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing earth working rollers are not effectively designed to break up solid substrates like concrete, as they either lack the necessary substrate breaking configuration or are not suitable for uniform processing and maneuverability on inclined surfaces.
Innovation Solution
The roller drum features a substrate breaking configuration with a grid-like pattern of impact bars and breaker bars, where impact bars are arranged in a circular direction and breaker bars are offset to ensure uniform rolling and prevent lateral drift, along with a vibratory arrangement to enhance crushing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a substrate breaking configuration with impact bars is provided on the roller drum, then the ability to break solid substrate like concrete is improved, but the complexity of the device increases
Solution Approach 1:
The substrate breaking configuration is segmented into two distinct functional components: impact bars arranged in a circular direction for breaking concrete, and breaker bars arranged in an axial direction for guiding and preventing lateral drift. This segmentation allows each component to perform its specific function efficiently while maintaining overall system manageability.
Solution Approach 2:
The roller drum is designed to perform multiple functions: it provides the structural support for the substrate breaking configuration, enables rotational movement for processing the substrate, and through the integrated breaker bars, provides lateral guidance and prevention of drift. This multi-functionality reduces the need for additional separate components.
2Stability of the object's composition
If breaker bars are arranged to prevent lateral drift on inclined surfaces, then the stability and uniform rolling motion are improved, but the device complexity increases
Solution Approach 1:
The breaker bars serve dual purposes: they guide the roller drum laterally to prevent drift on inclined surfaces, and they work in conjunction with impact bars to break the substrate into grid-shaped segments. This multi-functionality achieves stability without requiring separate guidance mechanisms.
Solution Approach 2:
The impact bars are arranged in a circular pattern around the roller drum axis, creating a curved configuration that naturally follows the rotational movement. This circular arrangement ensures uniform distribution of impact forces during rotation and contributes to stable rolling motion.

AI summary
An earth working roller for use in an earth working machine includes a roller drum, which extends in a direction along a roller axis of rotation, surrounds a roller interior, and has a circular outer circumferential contour, wherein a substrate breaking configuration is provided on the outer circumferential surface of the roller drum. The substrate breaking configuration includes a plurality of impact bars along the roller drum in the direction of the roller drum axis of rotation, as well as a plurality of breaker bars along the roller drum in a circumferential direction.
