Mobile Conveyor Machine for Continuous Mining Structure Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing conveyor systems in mining operations require significant downtime for the removal of conveyor structure as the mining progresses, as the conveyor shortens, leading to inefficiencies in mining operations.
Innovation Solution
A movable machine is integrated into the main conveyor system, featuring a support frame with storage pods for the conveyor structure, a mechanism to lift the top belt, and rollers for the return belt, allowing for the efficient storage and removal of conveyor components without halting mining operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the conveyor structure is removed manually as the mining progresses, then the conveyor length is reduced appropriately, but the mining operation must shut down for a significant amount of time
Solution Approach 1:
The patent applies the dynamics principle by introducing a mobile machine that can move along the conveyor and dynamically adjust its position as mining progresses. The machine transitions from stationary to mobile, allowing conveyor structure removal to occur without shutting down the mining operation. The mobile machine travels with the mining face, continuously removing conveyor sections as needed.
Solution Approach 2:
The mobile machine performs self-service by autonomously removing conveyor structure sections as it moves along the conveyor. The machine includes its own propulsion system and carries cutting tools, allowing it to independently cut and remove conveyor sections without requiring external assistance or shutdown of mining operations.
2Productivity
If the conveyor structure is removed quickly to minimize downtime, then productivity is improved, but the complexity of the removal system increases
Solution Approach 1:
The patent applies segmentation by dividing the conveyor structure into removable sections and using a mobile machine to remove them individually. The conveyor is segmented into discrete sections that can be cut and removed separately, allowing the removal process to be performed in a systematic manner without requiring complex overall system changes.
Solution Approach 2:
The mobile machine embodies multi-functionality by combining propulsion mechanisms, cutting tools, and material handling capabilities in a single device. This universal machine can perform multiple functions (moving along the conveyor, cutting structure sections, removing debris) without requiring separate specialized equipment for each task.

AI summary
A storage platform is incorporated into the main conveyor. The machine is movable, and incorporates space for the storage of main conveyor structure. The machine also includes a mechanism for raising the top of the endless belt, and for permitting the lower or return portion of the endless belt to pass through the mobile machine.
