In the grain equalizer B according to the present invention constructed as described above, the hopper 3 itself swivels, and the lower opening 3b for discharging the grains received from the upper opening 3a is a geared motor M1 having a swivel axis. Since it slowly swivels around the output shaft 61 so as to sequentially change its position, it also serves as the inclined diffusion plate 5 in the conventional means. Since the gear box 34 and the like for accommodating the reduction mechanism can be omitted, the parts inspection can be remarkably reduced and the cost can be reduced.

Moreover, since the dispersion plate 4 is driven by another geared motor M2 and separated from the hopper 3 which also functions as an inclined diffusion plate, the assembly and maintenance can be remarkably facilitated.
