It is urged to press against the soil surface, and it is provided to backfill the groove after fertilization.

Explaining the operation of the above example, when seedlings are placed on the seedling tank 20 and each part is driven by the engine 10, the passenger towing vehicle 1 is propelled by the rotation of the front wheels 5 and the rear wheels 7, and the transplanter 18 parts are leveled. Part of the load is received by the floats 22, 23, 23 to be pulled, and power is transmitted from the front transmission case 3 side to the input shaft in the transmission case 19 via the transmission shaft.
In this way, power is transmitted from the input shaft in the transmission case 19 to the drive shaft 28 via an appropriate transmission route. Then, each rotating case 29 rotates, and with this rotation, the counter planetary gears 32, 32 are planetarily rotated around the sun gear 31.
The planetary gears 33, 33 that mesh with this will be rotated. Therefore, the implant main body 35 is provided via the implant drive shaft 34 and the mounting bracket 42 integrally provided on the planetary gears 33, 33.
a is rotated. Further, the cam body 39 integrally attached to the rotating case 29 via the boss portion 39a is rotated while being displaced with respect to the rotation of the implant body 35a. Therefore, the interlocking member 38 is used for this purpose. The seedling pushing fork 37 is moved up and down.

That is, the tip end side of the seedling transplanting nail 36 operates along the transplanting locus P, and the seedling tank 20 that reciprocates left and right moves the seedling dividing port of the seedling receiving plate 26.
27, 27… The seedlings that are fed out one after another are divided and transferred one after another to the field scene, and when the seedling division 36 plunges into the soil surface at the bottom end (at the P1 position), the seedling extrusion fork 37 is exactly The seedlings are pushed downward by the action of the spring 40 and transplanted.

Then, when there is a difference in the seedling dividing amount by the seedling transplanting nails 36, 36 of the two transplanters 35 attached to the rotating case 29 or the seedling transplanting posture is not good, the transplanter driving shaft 34 is transplanted. Rotate the tool body 35a so that the seedling transplanting nail 36 moves the seedling dividing opening 27
It is advisable to adjust the size and angle of intervention. For this adjustment, loosen the bolts 43 and the mounting brackets 42 and the implant body.
The mounting angle with respect to 35a may be adjusted, but since this adjustment can be performed outside the implanter main body 35a, the operation can be extremely facilitated.

In addition, the seedling transplanting nail 36 is used at the seedling dividing port 27 of the seedling receiving plate 26 during seedling division.
On the other hand, if the cotter pin 44 is laterally displaced, the cotter pin 44 may be loosened, the implant device main body 35a may be appropriately moved in the axial direction, and the cotter pin 44 may be driven again for adjustment.

Then, the connecting member 60 is also rotated by the rotation of the rotating case 29 due to the seedling transplanting work, the feeding roll 52 of the fertilizer feeding section 49 is rotated through the connecting rod 65, the arm 67, and the one-way clutch, and the fertilizer is fed into the fertilizer transfer section 50. To fall. On the other hand, even if the drive rotating disk 58 is rotated through the transmission belt 74 and the driven pulley 71 and the straw or the like floats in the field, the straw or the like is properly embedded in the soil to form a groove on the soil surface. Since the fertilizer has been formed, the fertilizer that has dropped in the fertilizer transfer section 50 is properly applied to the groove, and is always applied to an appropriate uniform depth. Then, the fertilized groove is backfilled with the soil cover plate 75, and the soil surface is flattened. However, fertilization work is carried out at the same time as the seedling transplant work.

Further, in particular, a connecting member 60 that connects the outer side of each of the plurality of implanters 35, 35 provided in the rotating case 29 is provided, and the rotating case 29, the implanters 35, 35 and the connecting member 60 form a closed loop shape. Since the above-mentioned framework configuration is adopted, each of the transplanters 35, 35 operates smoothly, and good seedling can be planted.

Further, the connecting member 60 is provided with a drive member 64 for driving the fertilizer feeding part 49 at a position eccentric to the shaft 28, and the rotation of the connecting member 60 is used to drive the fertilizer feeding part 49 of the fertilizer application device 46. Because of this, the fertilizer feeding section 49 can be driven with a simple structure, the fertilizer feeding can be smoothly performed, and good fertilization work can be performed.

In the above embodiment, the circular plates 58, 59 of the rotary groover 51 are
Only one of them was set to drive and rotate.
Both 8, 59 may be provided so as to be driven and rotated by the rotating case 29.
