The utility model relates to a building construction machinery field provides an even distributing device and mixer, and it is high to have solved mixer manufacturing cost, the problem of product output and inefficiency. A mixer, includes agitating unit, to the storage device who carries the drier in the agitating unit, is equipped with even distributing device between agitating unit and the storage device, and even distributing device includes that the cloth fights and set up the agitator that is used for stirring the drier in the cloth is fought, and cloth fill top is equipped with the pan feeding mouth, the bottom that supply storage device input material and is equipped with the discharge gate that is used for exporting the material to agitating unit, the discharge gate is equipped with the headstock gear, the last water filling port that supplies water and pour into into that is equipped with of agitating unit. Stir mixing the drier through even distributing device, it is even enough to make the drier distribute before getting into agitating unit water injection stirring, has reduced the churning time of agitating unit to mixing the drier, has improved the atress condition ofmixing arm among the agitating unit simultaneously, has reduced manufacturing cost, has improved work efficiency.
