DISCHARGING MECHANISM FOR METERING CONTAINER

摘要

PROBLEM TO BE SOLVED: To prevent decrease in water-tightness and damage of sealing caused by aggregate existing between a container main body and a bottom lid from being generated. SOLUTION: A discharging mechanism 21 of a metering container is constituted in such a way that fine aggregate is stored with water as an aggregate immersed in water under a condition where the bottom lid 9 is closed in a metering container 11 to perform metering of the aggregate immersed in water and the aggregate immersed in water after the metering is finished is discharged downward by opening the bottom lid 9. In addition, for the discharging mechanism 21 of the metering container, an air jetting nozzle 24 as a gas spraying mechanism communicated and connected with an air compressor 22 through a hose 23 is fixed on a nozzle fixing part 25 stood in the neighborhood of the bottom lid 9 on an L-shaped fitting arm 13 in such a way that air flow can be sprayed on the top face of the bottom lid 9 from the apex of the air jetting nozzle 24 under a condition where the bottom lid 9 is opened.
