PURPOSE:To reduce a head as well as to make operation yet simpler, by accumulating powdery granules on a support floor where distribution conveyors are set up radially, while constituting these conveyors so as to get driven in a selective manner. CONSTITUTION:Powdery granules are accumulated on a conical umbrella 17 installed on a support floor 13. With a rotary paddle 16 rotated, a radial screw conveyor 15 laid under the surface of said floor 13 is selectively driven properly whenever occasion calls. In this way, powdery granules are scraped together on the screw conveyor 15 by means of the rotary paddle 16 and carried out by said conveyor 15. With this constitution, a head becomes smaller and distribution and carrying out of the powdery granules can be thus achieved with suchlike simple operation. |
