Collapsible Mobile Crusher With Flexible Rubber Hopper
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile rock crushing and screening plants face challenges in collapsing systems that result in leakage of fines material and require excessive labor, while also encroaching on space needed for material transfer when folded forward, and often necessitate more expensive wider conveyors or limited height reduction.
Innovation Solution
A pivoting collapsible material processing unit with a rubber hopper hingedly and slideably coupled to a conveyor, allowing the hopper to translate along the conveyor's longitudinal direction and collapse without human intervention, featuring a flexible hopper with edge plates for positive containment and a selectable maintenance position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the fines conveyor is folded forward when the system is collapsed, then the height restriction is met, but the space needed for transferring material off the mobile platform is encroached upon
Solution Approach 1:
The plant is divided into separable components: the fines conveyor remains fixed to the mobile frame while the rubber hopper is detached and repositioned. This segmentation allows the fines conveyor to stay in its optimal position for material transfer without being folded forward, thus preserving the required space while still achieving height reduction through the hopper repositioning.
Solution Approach 2:
The rubber hopper acts as an intermediary element between the vibrating screen plant and the fines conveyor. By repositioning this intermediary component (detaching it from the bottom of the screen and relocating it), the system achieves height reduction without compromising the spatial arrangement of the fines conveyor, thereby maintaining both height compliance and material transfer space.
2Extent of automation
If a rubber hopper is fixed at the bottom and pivoted, then the system can be collapsed, but leakage of fines material occurs and extra human involvement is needed
Solution Approach 1:
The rubber hopper is designed to be self-contained with integrated sides and a bottom that form a complete enclosure. When repositioned and secured to the fines conveyor, the hopper automatically maintains proper alignment and containment without requiring human intervention to ensure optimal folding or positioning, thereby eliminating both leakage risks and the need for extra human involvement during collapse operations.
3Length of stationary object
If the vibrating screen plant is lowered and moved forward for transportation, then height reduction is achieved, but the rubber hopper may not collapse optimally without human intervention
Solution Approach 1:
The rubber hopper is designed with flexible sides and a bottom that can dynamically adapt to the movement of the vibrating screen plant. As the plant is lowered and moved forward, the flexible hopper naturally conforms to the changing geometry and maintains its containment function throughout the transition, eliminating the need for human intervention to guide or adjust the collapse process while achieving the required height reduction.

AI summary
A mobile collapsible screen and cone crusher combination where the screen is pivoted forward and downward for transport and a rubber hopper is coupled to the fines conveyor so as to permit a hinged connection and a sliding connection between the flexible hopper and the fines conveyor. A plurality of flexible matter edge plates are used at the rear of the flexible hopper to facilitate proper compression and expansion of the flexible hopper. A selectable maintenance catch is used to allow the screen to be elevated to an intermediate height for maintenance.
