To provide a mixer of earth and sand gathered on-site agitating and mixing the same satisfactorily rationally by enabling adjustment of a water adding stage when the earth and sand are mixed by a flowing-down action and agitated by an agitator.
In the mixer of the earth and sand gathered on-site, a hollow transportation passage is demarcated, the mixing material is supplied to the transportation passage from the upper end of a mixing tube which is obliquely arranged from the upper end to the lower end and which has a plurality of agitators each driven by a motor mounted in multi steps along the oblique direction in the transportation passage, and the mixing material flowing-down while being mixed in the transportation passage is agitated by the agitator, and the mixing material mixed and agitated in the transportation passage is discharged from the lower end of the mixing tube. The mixer is equipped with: the mixing tube 2 from whose upper end the earth and sand gathered on-site and cement as the mixing material are supplied; the first agitator, of the agitators 8 in the mixing tube, mounted on the uppermost step to mix the mixing material in a dry state; and a water supply part 35 mounted on the downstream side of the first agitator along the flowing-down direction of the mixing material to supply water to the mixing material flowing-down in the transportation passage.
