Conveyor Impact Bed Intermediate Bar for Belt Wear Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conveyor belts in the mining and material handling industry face significant wear and damage at the junctions of impact beds due to abrupt angular changes, leading to frequent maintenance needs and potential belt damage from impact forces.
Innovation Solution
An impact bed design with a third resilient impact bar having an intermediate angled orientation between the planar and troughing angled bars, which is removable without taking out adjacent bars, providing a more gradual angular transition and additional support at the belt junction to reduce wear and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If impact bars are arranged with abrupt angular changes from planar to troughing configuration, then the troughing effect is achieved, but wear and damage occur at the belt junction
Solution Approach 1:
The impact bed is segmented into multiple impact bars with different orientations (planar, intermediate, troughing) rather than a single abrupt angle change. This segmentation allows the belt to transition gradually through multiple stages, reducing stress concentration and wear at any single junction point.
Solution Approach 2:
Different sections of the impact bed have different local qualities - the planar portion provides initial support, the intermediate angled bars provide gradual transition, and the troughing angled bars provide final belt containment. This local differentiation optimizes both troughing effect and belt protection.
2Stability of the object's composition
If impact bars are fixed in position, then structural stability is maintained, but maintenance and replacement become difficult
Solution Approach 1:
Each impact bar is treated as a separate, removable segment rather than a fixed integral part of the structure. This allows individual bars to be easily removed and replaced without affecting the stability of the overall impact bed structure, as each bar independently performs its function.
Solution Approach 2:
The impact bars are designed to be dynamically replaceable while maintaining structural stability during operation. The bars can be easily removed when worn and reinstalled to maintain the stable troughing configuration, combining ease of maintenance with structural integrity.
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
The design minimizes wear and damage at the belt junction by providing a more gradual angular change and additional support, extending the lifespan of the impact bars and reducing maintenance needs.
Implementation Method 1
These support members have a plurality of resilient impact bars secured thereto, which extend thereacross running lengthwise in the belt travel direction. The bars absorb the impact forces and decrease the acceleration of the materials or rocks dropped onto the belt.

AI summary
An impact bed for supporting a conveyor belt in a troughing configuration. The impact bed has a plurality of resilient impact bars running lengthwise in a travel direction of the conveyor belt. The plurality of resilient impact bars includes at least a first resilient impact bar having a planar orientation, a second resilient impact bar having a troughing angled orientation and a third resilient impact bar between the first resilient impact bar and second resilient impact bar. The third resilient impact bar has an intermediate angled orientation that is greater than the planar orientation of the first resilient impact bar and less than the troughing angled orientation of the second resilient impact bar. The third resilient impact bar is removable from the impact bed without removing the first resilient impact bar or second resilient impact bar from the impact bed.
