Apparatus for preparing a mixture
First Claim
1. An apparatus for preparing descrete batches each of which contains a mixture of predetermined quantities by weight of components, comprising a stationary hopper divided into a plurality of compartments for receiving separate components and separate outlet openings for discharging a component from each said compartment, base means fixedly mounting said hopper in a particular location respectively;
- a mixing and weighing structure comprising weighing means provided with force absorbers, a mixing vessel supported at least in part by said force absorbers, a movable base supporting said mixing and weighing structure, said movable base being adapted to move said mixing and weighing structure from adjacent to said hopper to other selected locations, said mixing and weighing structure further including a plurality of metering conveyor means having inlet openings and means for detachably connecting said conveyor inlet openings with said hopper discharge outlets, respectively, for metering and delivering said components separately to said mixing vessel, and control means on said movable base for coupling said weighing means with said metering conveyor means for successive operation of each metering conveyor means, thereby separately delivering to said mixing vessel a weighed quantity of each component for each separate batch.

Abstract
An apparatus for preparing a mixture, such as mortar, with predetermined quantities by weight of the components, such as sand, cement and the like, a supply of which is present in container compartments 4, 5 of e.g. hopper 1. The container compartments are each connectable to a metering conveyor 11, 12 of the apparatus. The apparatus is further provided with a mixing vessel 13 having stirring means, the vessel being supported at least partly on force absorbers 14 of weighing means. The weighting means are coupled with control means 15 for successively putting into operation the metering conveyor means for the various components.

3. An assembly for preparing a plurality of descrete batches each of which includes a mixture of predetermined quantities by weight of components comprising a hopper for such components, said hopper being stationarily fixed at a single location, and a mixture preparation unit detachably connectable thereto, said hopper having a body portion of rectangular configuration and an outlet portion in the form of an inverted truncated pyramid having a rectangular base and terminating in a lower inclined face, at least one partition being provided within the hopper to establish compartments terminating at said face and forming closable outlet openings, said outlet openings being bounded by an inclined coupling flange;
said mixture preparation unit being mounted in a frame which includes means for moving said unit from adjacent to said hopper to other locations which are spaced from said hopper, said unit further including means for weighing said vessel and its contents, and control means on said movable frame for controlling said conveyors in a predetermined mixing program in accordance with weighing signals derived from said weighing means, said mixing vessel having a conveyor which is provided with inlet openings arranged at the same angle of inclination as said coupling flange on said hopper and having means for detachably connecting said inlet openings to said hopper outlet openings for receiving material therefrom.
