Mobile Crusher Discharge Conveyor Decoupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile crusher systems face vibration issues due to the high weight of lumpy material, which affects the loading and discharge conveyors, leading to reduced service life and operational instability.
Innovation Solution
The discharge conveyor device is decoupled from the crusher system and designed as a separately movable unit with its own chassis, eliminating the rigid connection between the feed conveyor, crusher, and discharge conveyor, thereby isolating vibrations and allowing flexible positioning and alignment for efficient material removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the discharge conveyor is rigidly connected to the crusher frame, then the structure is simpler, but the discharge conveyor is exposed to high vibration loads from lumpy material, reducing its service life
Solution Approach 1:
The mobile crusher system is divided into two independent units: the crusher unit with its own running gear, and the discharge conveyor unit with its own running gear. This segmentation allows each unit to independently absorb and manage vibrations, preventing the transmission of high vibration loads from the crusher to the discharge conveyor, thereby extending the discharge conveyor's service life while maintaining reasonable structural complexity
Solution Approach 2:
The discharge conveyor is extracted from the crusher frame structure and positioned independently on the ground with its own running gear. This extraction removes the discharge conveyor from the vibration-prone crusher structure, allowing it to operate in a more stable environment and significantly reducing vibration-induced wear and damage
2Stability of the object's composition
If the discharge conveyor is rigidly connected to the crusher frame, then the positioning is more stable, but the flexibility and adaptability of the discharge conveyor are reduced
Solution Approach 1:
Both the crusher unit and discharge conveyor unit are equipped with independent running gears, enabling dynamic positioning and movement. The discharge conveyor can be independently positioned and oriented to suit different operational requirements while maintaining operational stability through its own chassis, achieving both flexibility and stability
3Volume of moving object
If the feed conveyor and discharge conveyor share the same frame, then the device is more compact, but vibrations from loading the feed conveyor are transmitted to the discharge conveyor
Solution Approach 1:
The system is segmented into separate operational units with independent support structures. The feed conveyor is supported by the crusher frame while the discharge conveyor is supported by its own running gear on the ground. This physical segmentation prevents vibration transmission between the two conveyors despite the functional connection through the crushed material flow
Solution Approach 2:
The ground acts as an intermediary support surface for the discharge conveyor's running gear, isolating it from vibrations generated by the feed conveyor and crusher. This intermediary support structure allows the discharge conveyor to operate independently without being affected by vibrations from the loading side
