逃げることができるのである。Therefore, the section in which the rotation of the planting shaft 7 in the left direction is stopped with respect to the revolution of the rotating case 4 corresponds to the field scene 18 of the planting rod 8.
By setting so as to correspond to the time of falling so as to approach, the planting rod 8 does not rotate leftward with respect to the revolution of the rotating case 4 when descending so as to approach the field scene 18, Change the posture downward from the previous state, and then rotate case 4 when ascending from the field scene 18.
By rotating again in the left direction by the revolution of, the posture is changed upward, so that the movement trajectory of the tip of the split claw 9 of each planting rod 8 is represented by a two-dot chain line in FIG.
The movement trajectory 19 of the substantially elliptical closed loop which is long in the up-down direction is obtained.
When entering the field scene 18, the planting shaft 7 becomes substantially vertical due to the rotation stop, so that the seedlings can be planted substantially vertically with respect to the field scene 18. By starting to rotate to the left, it rises upward while rotating upward, so that it can quickly escape from the seedling after planting.
