ABSTRACT:
A gate for supplying granule to and removing it from the other apparatus, Which comprises: a drive source (2); a fixed gate (6) having multiple feeder holes arranged such that granule can pass through; a movable gate (7) that is attached such that it can slide across the fixed gate (6) and is equipped with multiple openings (71) that have the same pitch as the feeder holes (61) on the fixed gate, and that allow granule to pass through when said openings (71) are aligned with said feeder holes; and a power transmission mechanism.
The granule gate lowers the height of the mounds of granule that accumulate in granule weighing machines (1). It can also entirely open and close feeding holes using a short stroke. The granule weighing machine (1) can be designed thin, so that the maximum quantity of granule to be weighed nearly matches the capacity of the weighing container (3).
