Concrete remix and transfer device

Abstract

A mobile concrete remix and transfer device includes an elongate open-topped surge bin, a remixing and transfer agitator rotatably mounted in the bin to move concrete toward one end, and an upwardly inclined discharge screw conveyor mounted in one end of the bin to transfer concrete therefrom to an upper discharge end near the upper edge of the surge bin. The device is particularly useful for direct or shuttle transfer hauling within the close confines of tunnel construction in a manner in which concrete can be loaded into and discharged from the bin at points directly adjacent the open upper edge thereof without the need for vertical lifting or tilting adjustment of the bin. The device may also be skid-mounted and positioned directly on the ground, loaded directly from a low discharge height truck mixer, and discharged directly into a concrete pump hopper, bucket, or the like.
