Abstract
A stage (3) for holding a boom body (4), which is composed of a plurality of boom components (15, 41, 42), is mounted on a tower mast (2) so as to be turnable by means of a servomotor. A servomotor (56, 61) for turning the next boom component is provided on the distal end of each boom component. Each boom component is provided with a belt conveyor, and granule that is pulled up from the ground to the position of the stage (3) by means of a bucket (5) is transported by means of the conveyor and thrown out from a boom body end (66). As this is done, the respective turns of the stage 3 and each boom component are controlled in accordance with the rotation of the servomotor, and the boom body end (66) is controlled, whereby the granule can be thrown out into any desired position within a operable range.
