PURPOSE: A ready-mixed concrete mixing apparatus is provided to be able to minimize the operating space by improving the gate structure of a concrete mixer, and to be able to reduce the manufacturing cost by configuring a simple structure for opening/closing the gate. CONSTITUTION: A ready-mixed concrete mixer is equipped with a mixer tank (100), a stirring means, and a gate member (500). A mixer tank has a storage space in which concrete materials are stored and mixed, and a discharge port (150) in the lower part for discharging mixed concrete materials to outside. The mixer comprises first and second stirring axis which are arranged within the mixer tank in a rotatable manner, a driving motor (310) which is arranged in one side of the mixer tank and rotated with the application of external power supply; a driving sprocket (330) which is connected in order to be connected by a connector connected to the motor shaft of the driving motor and is arranged on one end of the first stirring axis, a driving gear (410) which is arranged on the other end of the first axis and has multiple gear teeth on the outer circumference, and a driven gear (420) which is arranged on an end of the second stirring axis, combined in gear with the driving gear and rotated, to stir the concrete materials stored in the storage space. |
