Then, when the motor 9 is energized and the seedling growing box 2 is supplied to the starting end of the transfer table 1 in this state, the seedling growing box 2 is transferred by the guide roll 3 and reaches the rowing roll 10. The rotation of the motor 9 is as follows: rotating shaft 15 → pulley 16 → belt 22 → pulley 20 → shaft 18 → pulley 21 → belt 27 →
Because the transmission is from the pulley 26 to the shaft 23 and rotates the striped roll 10,
Beautiful grooves 25 are formed on the surface of the soil bed 24,
The seed rice 7 is guided into the grooves 25 by the row sowing body 11 and is sown in rows.

When it is further transferred and reaches the pressure roller 12, the rotation of the motor 9 is as follows: rotating shaft 15 → pulley 17 → belt 43 → pulley 39 → shaft 36 → pulley 38 → belt 42 →
The force is transmitted from the pulley 41 to the shaft 40 and rotates the pressure roller 12, so that the pressure is suppressed and the row sowing is completed.
