RECLAIMING SYSTEM AND METHOD

WIPO Patent Application WO/2022/012116

A1

A reclaiming system and method, comprising a laser scanning device (4) and a control unit (5). The control unit (5) is configured to perform the following steps: obtain a stockpile model; calculate the number of material layers in a region to be reclaimed; divide a stockpile region into a plurality of regions to be reclaimed; use said region located on the uppermost layer as a target region to be reclaimed, and obtain a reclaiming entry point of said target region; calculate target attitude data corresponding to the reclaiming entry point; control a reclaimer to move to the target attitude; control a boom (2) to rotate by a preset first direction; determine in real time whether the position of a bucket wheel (3) reaches the reclaiming boundary of said target region; if yes, control the boom (2) to decrease the rotational speed; control a bogie (1) to move to the next reclaiming position; and rotate the boom (2) by a second direction and continue performing a reclaiming operation. The reclaiming system can achieve an automatic reclaiming operation, and solves the existing safety problem of the personnel and equipment caused by the manual operation of the reclaimer.
