Abstract
Apparatus for metering and feeding aggregate materials for the production of concrete is constructed so as to be transportable as a unit. To this end, the frame of the apparatus is in two parts which are pivotally connected with one another, the one, fixed, part accommodating metering apparatus, and the other, movable, part accommodating an elevated storage and mixing apparatus. The movable part pivots down into a transporting condition and up into its operating condition. The two frame parts together provide an inclined path for a charge box by which metered quantities of aggregate are transferred from the metering apparatus to the mixing apparatus. Various damping devices are provided for preventing undue vibrations at the start and end of the movement of the charge box.
Claims15
Apparatus, transportable as a unit, for metering and feeding aggregate materials for the production of concrete, said apparatus comprising a frame, which serves at least partly as a support arrangement for storage containers for the aggregate materials and which accommodates a metering apparatus and a feed apparatus together with a storage and mixing apparatus in both a transporting and elevated operating position, wherein the frame comprises two parts, one of which supports the metering apparatus and the other of which supports the storage and mixing apparatus in both said transporting and elevated positions, pivot means for pivotally connecting said two frame parts with one another whereby said other part can be moved about said pivot means relative to said one part, thereby enabling the apparatus to be converted from said elevated operating position into a transporting position and a transporting position to an operating position, and a tie-bar connecting said two parts together in said transporting position to mutually brace said parts thereby, and wherein the feed apparatus comprises a charge box which is movable along an inclined path, which path is provided by said two frame parts.
