摘要

PROBLEM TO BE SOLVED: To increase allowable stock quantity by holding a powder carrying passage and a discharge port at high positions for effectively utilizing the whole range of a stock place, and equalizing powder stacking height along the whole body for eliminating a dead zone. SOLUTION: A movable conveyor 14 positioned right under a fixed feed port 12 for sand and soil 11 fixed above a stock place P to horizontally carry the sand and soil 11 received from the fixed feeding port 12 is provided, with the discharge port 13 for the sand and soil 11 carried provided to be movable in a carrying direction. A discharge conveyor 16 is provided to be positioned right under the discharge port 13 of the movable conveyor 14 to horizontally move synchronously with movement of the discharge port 13 to horizontally carry the sand and soil 11 received from the discharge port 13 in a perpendicular direction to the carrying direction of the movable conveyor 14. The discharge conveyor 16 is provided with a discharge port 15 for the sand and soil 11 carried to be movable in the carrying direction of it.
