PURPOSE:To obtain a soil mixer for rice transplanter, having a rotating drum and concentric circular arc bottom plate with an interval from the above- mentioned drum on a frame and constituted so as to take out mixed soil with the aforementioned circular arc bottom plate and capable of reducing load on a motor in taking out the mixed soil. CONSTITUTION:An opening and closing lid 14 is removed to charge soil and a fertilizer from an inlet and outlet 13 to almost half in a rotating drum 6. The inlet and outlet 13 is then closed with the opening and closing lid 14 and a motor 27 is operated to rotate the drum 6 in the direction (a). Thereby, the soil is homogeneously mixed with the fertilizer to prepare mixed soil 12. The rotation of the drum is subsequently stopped to remove the lid 14 and the drum 6 is further rotated to drop the mixed soil 12 from the inlet and outlet 13 into a space part 6 when the inlet and outlet 13 reaches the under side. About half of the dropped mixed soil 12 is then discharged from a discharging port 17 to the outside of the mixer by the first scraping out unit 19 and the residual soil is discharged from the discharging port 17 to the outside of the mixer by the second scraping out unit 24. As a result, the mixed soil 12 in the space part 16 is taken out of the frame 1 in two stages. |
