In this embodiment, since two seedling planting tools 34 are attached to the rotating case 22, seedling planting can be performed at high speed.

When the seedling planting is to be stopped next, such as when turning, the planting clutch lever 14 is operated to push in the clutch bin 49 via the wire 50, and the driven clutch body 47 is pushed in.
It is only necessary to contact the cam surface (b) of the fixed position stop F cam 47a. Then, the driven clutch body 47 moves against the spring 48, and the clutch pawl of the driven clutch body 47 is disengaged from the clutch pawl of the drive clutch gear 46, and the rotation of the drive shaft 43 is stopped at that position.

At this time, the fixed position stop cam 47a is connected to one rotating case 2.
Since the number of seedling-planting tools 34 corresponding to the number of seedling-planting tools 34 attached to 2 is provided, when the planting clutch lever 14 is operated to the stop side, the seedling-planting tools 34 are always stopped immediately. This also applies to the fact that two 1-piece planting tools 34 are attached to one rotating case 22. After the stop operation is applied, the 45-planting tool 34 divides the 1 night from the 1°h mounting table. There will be no unforeseen situations such as planting them in the wrong place.

In the embodiment of the transmission formation shown in FIG. The drive shafts 23a and 23b are connected by an intermediate pin shaft that is inserted into the axis of the planting drive shaft and is rotatable, and to this,

At this time, the subtitle planting clutch 56 is also provided with the same number of fixed position stop upper positions as the main seedling planting clutch 45 as the overnight planting tools 34 attached to the same rotation case.
This prevents an unexpected situation in which the rotation of the seedling planting tool 34 is stopped almost at the same time as the antibacterial planting clutch 56 is disengaged, and the seedlings are divided and planted on the seedling mounting table after the stopping operation. I won't let you wake up.

As explained above, in the present invention, the camshaft 32 and the cylindrical shaft 31 . Where should the seedling planting tool 34 be attached? The case body 35 on the shaft side 1a side of the + shaft 31 is fixed via the metal 60, and the support shaft 41 of the interlocking rod 37 operated by the cam 36 can be inserted and removed from the metal 60 side,
Since the metal 60 also serves as a member for removing the support shaft 41, the support shaft 40 can be brought closer to the cam 36 side, and the longitudinal length of the seedling planting tool 34 can be shortened. It is now possible to obtain a seedling planting device, and when the metal 60 is removed from the planting case when the cam 36 is removed from the planting case, the support shaft 41 of the interlocking rod 37 can also be taken out gracefully, and disassembled. Assembly becomes extremely easy.
