With the adjustment of 7), the position where the seedling removal claw (17) enters the seedling mounting table (15) is adjusted by adjusting the mounting position of the mounting plate (67) by the long hole (83) of the bolt (82a). It can be easily adjusted to stabilize the seedling collecting performance and improve the reliability of planting.

る。Further, during the feeding of the seedlings from the seedling tray (16) by the seedling removal nails (17) and supplying the seedlings to the planting nails (19), the seedlings are released from the seedling removal position. The seedling removal claw (17) is not immediately released immediately after the seedling removal claw (17) swings down to the position, but linearly moves along the buffer groove (c) of the guide groove (28) once. Is slightly released, the kinetic inertia generated when the seedling removal claw (17) descends from the seedling removal position to the seedling release position is moved along the buffer groove (c). Can be effectively attenuated and planted nails (19)
It is possible to reliably supply the seedlings from the seedling removal nails (17) in a good posture and improve the planting accuracy.

を奏する。[Effects of the Invention] As is apparent from the above embodiments, the present invention is directed to a seedling tray (1) of a seedling table (15) that is reciprocated right and left.
6) In the structure provided with a seedling extraction drive mechanism for extracting a seedling with the seedling extraction nail (17) to be reciprocated and oscillating and supplying the seedling to the planting nail (19) to transplant the seedling. A movement buffer unit (10) for reducing the kinetic inertia of the seedling removal claw (17) at the trailing end position of the seedling removal trajectory from the seedling removal position of the removal nail (17) to the seedling supply position to the planting nail (19). c) is provided, so that the kinetic inertia force generated during lowering the seedling extraction nail (17) from the seedling extraction position to the seedling supply position is reduced, and the seedling extraction nail (17) is planted from the seedling extraction nail (17). 1
A remarkable effect is achieved such that the posture to 9) is good and the seedling can be reliably supplied, and the planting accuracy can be improved.
