PURPOSE:To make it possible to stack up bulk materials to a higher level with the use of even a short boom, and as well to make it possible to stack up bulk materials and to scrape and transfer the same, by providing a trough to a scraper boom such that a return side scraper may slide in the trough. CONSTITUTION:When bulk materials 2 are stacked up on a stacking bed 25 laid on the ground 3, at first a scraper boom 5 is set at its maximum rising position by means of a crane device 13. Then bulk materials 2 which have been transferred by a ground conveyor 7 are transferred to a chute 10, and are then dropped onto a scraper conveyor 20. Therefore, the bulk materials 2 are scraped up through a trough 6 by means of a stacking scraper 14a, and are discharged, for stacking, from the tip end of the trough 6 to the stacking bed 25 through the opening 18 of a support frame 15 and the inside of a scraping side scraper 14. At this time, by extending the trough 6 to one of positions (a) through (j) which determines the stacking height of the bulk cargo, several kinds of bulk materials 2 may be stacked up, in strata. |
