Abstract
In order to make good-quality concrete, a concrete mixer for mixing materials of concrete by rotation is provided so as to enhance fluidity of a mixture. A mounting frame 7 supporting a drum 2 of a concrete mixer 1 fixes a vibration device 25 via a mounting plate 21. A pair of arms 20 is integrally formed with both ends of the mounting plate 21, while rollers 24 rotationally supported by one ends of the arms 20 respectively contact the outer periphery of the drum 2. A vibration of the vibration device 25 is transmitted from the rollers 24 rotatably supported by the pair of arms 20 to the drum 2, so that the drum 2 vibrates while it rotates. Accordingly, a mixture is liquefied, and thus concrete having a good quality can be produced.
Claims3
A concrete mixer rotatably supporting a drum to a mounting frame and rotating said drum while using a driving motor so as to mix various kinds of materials in said drum, comprising:
- a vibration device fixed to at least said mounting frame;
- and
- a vibration transmitting means for transmitting a vibration of said vibration device to said drum is provided on said mounting frame, said vibration transmitting means comprising:
- a pair of arms integrally protruding from said mounting frame;
- rotation members rotatably supported by ends of said pair of arms respectively, said rotation members contacting said drum,
- wherein said drum has a cylindrical shape having an open end and a bottom portion, said drum including a plurality of agitating blades inside thereof,
- wherein said mounting frame has a bearing on a central part thereof in order to rotatably support a rotation shaft, said shaft being provided on the bottom portion of said drum in a protruding manner;
- and
- wherein said vibration device is fixed adjacent to said bearing.
A concrete mixer for fixing a drum to a mounting frame and mixing various kinds of materials in said drum while rotating agitating blades provided inside said drum.
- wherein said drum has a cylindrical shape having an open end and a bottom portion;
- wherein a vibration device is provided on the bottom portion of said drum;
- wherein an elevation driving means is provided for moving said agitating blades up and down;
- wherein said mounting frame comprises a slope member for fixing said drum and said agitating blades;
- and
- wherein said drum is rotatably fixed to said slope member.
