Description

FIG. 1 is a front view of a design for a measuring hopper for a combined weighing instrument according to the present invention.

FIG. 2 is a rear view of the measuring hopper of FIG. 1.

FIG. 3 is a top view of the measuring hopper of FIG. 1.

FIG. 4 is a bottom view of the measuring hopper of FIG. 1.

FIG. 5 is a left side view of the measuring hopper of FIG. 1.

FIG. 6 is right side view of the measuring hopper of FIG. 1.

FIG. 7 is a front perspective view of the measuring hopper of FIG. 1.

FIG. 8 is a rear perspective view of the measuring hopper of FIG. 1.

FIG. 9 is a front perspective view of the measuring hopper of FIG. 1, showing a gate of the measuring hopper in an open state.

FIG. 10 is a rear perspective view of the measuring hopper of FIG. 1, showing the gate of the measuring hopper in an open state; and,

FIG. 11 is a front view of the measuring hopper of FIG. 1, shown positioned in a combined weighing instrument, which is illustrated in broken lines.

The dashed lines in FIG. 11 illustrate a combined weighing instrument which includes a plurality of measuring portions, each for holding a respective load of bulk material, and which discharges the material from a subset of the measuring portions with loads that have been measured to have a combined weight that is within an allowable range of a combined target weight. The material to be measured is put in an input port of the measuring hopper of the claimed design in a state in which a gate is closed, by a pool hopper of a combined weighing instrument, whereby the measuring hopper can temporarily retain the material to be measured. Further, if a drive apparatus of the combined weighing instrument oscillates upward an oscillating arm of the measuring hopper, a gate of the measuring hopper is opened, whereby the measuring hopper can discharge the retained material to be measured from a discharge port to a collecting chute. The broken lines form no part of the claimed design.

Claims
