Abstract
A measuring apparatus of submergence aggregate according to the present invention comprising a stock bin for storing fine aggregate, a fine aggregate feed hopper placed under the stock bin, a vibrating feeder placed under a discharge opening of the fine aggregate feed hopper, a screen device placed in the vicinity of an exit of the vibrating feeder, a measurement tank placed under the screen device, an electrode-type displacement sensor as means for measuring a water level placed above the measurement tank, and load cells as mass measuring means for measuring a mass of the measurement tank.
Claims5
A discharge mechanism of a concrete-material-measurement container comprising:
- a bottom lid;
- and
- a gas spraying mechanism provided in the vicinity of said bottom lid,
- wherein, the bottom lid, when closed, contains aggregate with water as submergence aggregate in the measurement container for measuring the submergence aggregate,
- wherein, the bottom lid, when opened, discharges the submergence aggregate downward after the measurement is finished, and
- wherein said gas spraying mechanism is configured to spray a top face of the bottom lid with a gas flow when the bottom lid is opened.
A discharge mechanism of a concrete-material-measurement container comprising:
- a bottom lid;
- and
- a gas spraying mechanism provided in the vicinity of said bottom lid,
- wherein, the bottom lid, when closed, contains aggregate with water as submergence aggregate in the measurement container for measuring the submergence aggregate,
- wherein, the bottom lid, when opened, discharges the submergence aggregate downward after the measurement is finished,
- wherein said bottom lid is opened or closed by moving it in a translation direction or rotating it within a level surface, and
- wherein said gas spraying mechanism is configured to spray a top face of the bottom lid with a gas flow when the bottom lid is opened.
A discharge mechanism of a concrete-material-measurement container for measuring concrete material, comprising:
- a bottom lid;
- and
- a gas spraying mechanism provided in the vicinity of said bottom lid,
- wherein, the bottom lid is configured to contain, when closed, concrete aggregate with water as submergence aggregate concrete material in the measurement container for measuring the submergence aggregate concrete material,
- wherein, the bottom lid, when opened, discharges the submergence aggregate downward after the measurement is finished, and
- wherein said bottom lid is opened or closed by moving it in a translation direction or rotating it within a level surface.
