Short axle 85a further rotates from above-mentioned state, pitman shaft 85c move to short axle 85a substantially directly below it Before, to release unit 98 and utilize cam 95d to start action, the nozzle component 98 at Seedling plantation utensil U1 is opened and shape While hole W1 is used in seedling plantation, received Seedling N is made to fall and plant.

Pitman shaft 85c moves the moment substantially directly below to short axle 85a, is that nozzle component 98 opens the maximum moment, Cursor 29 and swing arm 135 are in the moment of linearity, are to uproot the moment that parts 131 decline minimum, at Seedling The precalculated position that formed of plantation hole W1 forms the end minimum for expanded hole W2 of bowl-type.

When swing arm 135 is by during with cursor 29 state linearly, the elongated hole 142 of activation part 134 just with Guide finger 132c combines and makes swing arm 135 rotate around pitman shaft 85c, and activation part 134 is the most counterclockwise Rotate up to abut with the base portion of swing arm 135.

In this condition, nozzle component 98 is opened maximum, but support rod 132 is lifted by force application part 133, start Parts 134 are moved up by the lifting of this support rod 132.

When actuating arm 29 rotates further because of short axle 85a, swing arm 135 becomes the state being pulled to back upper place, Activation part 134 rotates because combining with guide finger 132c, and limiting unit 134a abuts with swing arm 135, but allows Support rod 132 moves up, and hoe parts 131 gradually become shallower as to being absorbed in of ridge R.

Further, when becoming the state that the crankangle shown in Figure 17 is 180 °, nozzle component 98 is from Seedling plantation hole W1 Extracting and proceed by closed action, hoe parts 131 are also extracted upward from ridge R.

Described expanded hole W2 is ratio Seedling plantation bowl-type big and shallow for hole W1, overlapping, in side with Seedling plantation hole W1 At the position of Seedling plantation hole W1 for the deepest when face is seen, it addition, when front is seen, Seedling plantation with the position of hole W1 because of Uproot the circular arc of the lower edge 131a of parts 131 and become the deepest, pour into the water in expanded hole W2 and concentrate on the deepest Seedling Hole W1 is used in plantation, effectively supplies in Seedling N.

Owing to the top of nozzle component 98 of Seedling plantation utensil U1 is most advanced and sophisticated shape, even if therefore hoe parts 131 dig from starting Pick expanded hole W2 charges in the R of ridge originally, and resistance is the least, it addition, expanded hole W2 will not be damaged.Owing to being initially formed Expanded hole W2, therefore, compared to the situation without expanded hole W2, can plant utensil with less resistance by Seedling later The nozzle component 98 of U1 inserts in the R of ridge deeper, forms deeper Seedling plantation hole W1, and can plant relatively by Seedling N Deeply.

Now explanation uses the transplanting operation of described seeding transplant machine 1.
