1 to 6 is a view of a method and apparatus for metering a mobile concrete mixture according to the present invention, Figure 1 is a diagram illustrating a process for metering a mobile concrete mixture, Figure 2 is a plan view of a metering device for a mobile concrete mixture 3 is a front view of a mobile concrete mixing device quantitative input device, Figure 4 is a side view of a mobile concrete mixing device quantitative input device, respectively, Figure 5 is a plan view of the input container, Figure 6 is a longitudinal cross-sectional view of the input container, respectively It is.

First, referring to FIG. 1, a batcher plant for manufacturing ready-mixed concrete (remicon) is schematically illustrated.

In the conventional batcher plant, cement and aggregate are supplied from the cement supply unit 100 and the aggregate supply unit 110 to the mixer 200 and mixed, and are introduced into the ready-mixed concrete truck 400 through the discharge hopper 300. Ready-mixed concrete truck 400 is moved to the construction site of the construction, including the building, bridges, etc., for placing.
