Stockyard joint reclaiming system and method

摘要

A stockyard joint reclaiming system includes an outer output conveyor, a scraper reclaimer provided with a scraper mechanism, an inner feeder, and an inner output conveyor arranged below a stockpile. The scraper mechanism includes a chain and a scraper installed on a chain. The chain moves forwards or backwards under the action of a driving device to drive the scraper to push materials to a corresponding discharging port. The scraper mechanism drives the scraper through forward or reverse operation of the chain for pushing the materials to the output conveyor and a reclaiming line can be selected. A reclaiming mode is flexible and more output lines are available. When the material level is lower than a horizontal position, the scraper is driven to move through a reverse operation of the chain to push the materials to an upper part of the inner feeder for realizing reclaiming, thereby reducing unnecessary energy consumption and effectively guaranteeing the reclaiming capability of the scraper reclaimer.
