Abstract: PURPOSE:To transfer a bulk cargo stably effectively by collecting the bulk cargoes from both sides to the central portion by a horizontal screw and flipping up them above the central portion with two paddle feeders. CONSTITUTION:Cargoes are scraped up from both sides by the rotation of a pair of paddle feeders 1 and a horizontal screw 2 and flipped upward by a centrifugal force. The cargo flipped up by the paddle feeder 1 is caught by a bulging portion of central portion 3a between flat pulleys 3 sandwiched be tween pulleys 4 having different diameters from the lower end opening of a flat belt conveyer and moved upward by a frictional force between the cargo and the belt caused by the pivoting of the flat belt 3 to be taken out of the conveyer end through the horizontal option. After passing through different diameter pulleys, the cross sectional area of cargo necessary for transfer is ensured by a pulley 4 and a holding roller 5 and further the overload on the belt is not generated since the cargoes more than an amount of cargo regulated by a gap between the central portions of a pair of different diameter pulleys 4 do not enter.
