<p>In a concrete mixer for kneading concrete raw material by rotation, fluidization of the raw material kneaded is increased so as to produce a high-quality concrete. A mounting frame (7) supporting a drum (2) of the concrete mixer (1) fixes a vibration apparatus (25) via a mounting plate (21). At both ends of the mounting plate (21), a right and a left arm (20) are integrally formed and rollers (24) axially supported at their tip ends are brought into contact with an outer circumferential surface of the drum (2). Vibration of the vibration apparatus (25) is transmitted from the rollers (24) axially supported by the arms (20) of the mounting plate (21) to the drum (2) and the drum (2) vibrates while rotating. This makes the kneaded material into a liquid state, thereby producing a high-quality raw concrete.</p> |
