BACKGROUND OF THE INVENTION
The present invention relates to a divided transfer device for a connected seedling group that divides a connected seedling group into two or more and transfers the divided connected seedling group to a seedling box.
[0002]
[Prior art]
Examples of conventional split transfer equipment include those shown in Japanese Utility Model Publication No. 4-37371 and Japanese Patent Application Laid-Open No. 7-79613.
In the split transfer apparatus described in Japanese Utility Model Publication No. 4-37371, when a linked seedling group is split, a seedling group split needle is inserted into the seedling forming the connected seedling group, and each split seedling group is transferred to a seedling. When transferring to the box, the needles for dividing the seedling group that have been inserted are extracted from the seedlings.
[0003]
The divided transfer device described in Japanese Patent Laid-Open No. 7-79613, after dividing the connected seedling group, rotates the divided connected seedling group upward to a posture for transferring to the seedling box, and between these operations The operation of pulling out the seedling group dividing needles inserted into the seedlings is performed separately.
