動作の繰返しにより、移植機を進行させながら土付苗が
圃場に植付けられる。In the above-described configuration, in the state shown in FIG. 1, the soild seedling is dropped and supplied from the seedling supply pot to the transplanting cylinder 5, and then the pushing member 3 having the same peripheral speed as the speed of the transplanting machine comes into contact with the abutment plate 22. As a result, the transplanting cylinder 5 is pushed at the same speed as the speed of the transplanting machine in the direction opposite to the traveling direction of the transplanting machine, and is moved backward and downward.
Therefore, the transplant tube 5 is moved downward at a relative speed O in the front-rear direction, and the shutter 14 is pushed into the field. Then, when the transplanting cylinder 5 reaches the vicinity of the lowermost position, the cam 4 provided on the rotating body 2 pushes the roller 25 backward, and the pushing rod 29 swings downward about the support shaft 27. Then, the engagement member 30 is pushed downward to move the lower cylinder 7 downward. As a result, the opening / closing link 16 is pivoted downward around the pivot 17 against the urging force of the spring 18, and the front lid 13 is moved forward around the support shaft 15 and the rear lid 13 is moved backward. The rocker swings, the shutter 14 is opened, and the soild seedling is dropped and transplanted into the planting hole formed by the transplanting tube 5. Next, the pushing member 3 is disengaged from the abutment plate 22, and the transplant tube 5 is pulled upward by the spring 11. At this time, the cam 4 is engaged with the roller 25, the shutter 14 is in the open state, and the shutter 14 of the transplanting tube 5 is separated from the soil in the field and reaches the uppermost position shown in FIG. The cam 4 is separated from the roller 25 and the shutter 14 is closed. Then, by repeating the above operation, the seedlings are planted in the field while the transplanter is advanced.

される。FIG. 2 shows a modified example of the rotating body 2, in which a plurality of mounting holes 32 for the roller 3 are formed in the radial direction, and the planting pitch of the soil seedlings can be changed. In this case, since the amount of vertical movement of the transplant tube 5 changes, the vertical mounting position of the support 10 and the mounting position of the cam 4 can be freely changed as appropriate.

る。(Effects of the Invention) According to the present invention, the moving cylinder is moved at the same speed as the traveling speed in the direction opposite to the traveling direction of the traveling aircraft by the pushing member rotated by the rotating body at the same peripheral speed as the traveling speed of the traveling aircraft. As it is pushed down and pushed down into the field, it is possible to easily secure the proper planting posture of the soild seedlings.

れ、植付姿勢が安定する。In addition, the transplanting cylinder descends in a substantially vertical direction, and the shutter at the bottom thereof enters the field, and after entering, the shutter opens by a pair of lids swinging back and forth in the traveling direction, so that the seedlings fall and release. The seedlings are released in a substantially vertical direction, and the planting posture is stabilized.
また、移動筒の下降時は、押動部材によって安定した
スピードで移植筒を移動でき、これによって苗を傾けず
に圃場に移送できる。In addition, when the moving tube is lowered, the transplanting tube can be moved at a stable speed by the pushing member, whereby the seedling can be transferred to the field without tilting.

となく速やかに上昇させることができる。Further, when the ground trajectory of the moving cylinder at the time of ascending is in a direction inclined with respect to the vertical direction, if the transplanting cylinder is raised at a very low speed because of the traveling body, the transplanting cylinder will be moved immediately after transplantation. Hit (or hook) the leaves of the seedling
In some cases, however, in the present invention, the transplanting cylinder can be instantaneously raised by a spring force at the time of lifting,
As a result, the seedlings immediately after transplanting can be quickly raised without hitting the transplanting cylinder.
また、移植筒は下降時には、安定したスピードで移動
でき、上昇時には、瞬時に上昇させることができるの
で、移植筒の昇降動作の1サイクルの時間が短縮でき、
株間を狭くする際に有利である。In addition, when the transplant tube is lowered, it can move at a stable speed, and when it is raised, it can be raised instantaneously.
This is advantageous when narrowing between stocks.
