The cam body 39 integrally attached to the body 9 via the boss portion 39a is rotated while being shifted with respect to the rotation of the implanting device main body 35a. 37 will be moved up and down. That is, the tip side of the seedling transplant nail 36 is the transplant locus P
The seedlings successively fed to the seedling dividing ports 27, 27... Of the seedling receiving plate 26 are divided by the seedling table 20 which reciprocates left and right, and are successively transferred to the field scene, where the seedling division 36 is performed. Is pushed into the lowermost soil surface (at the position P1), the seedling pushing fork 37 pushes the seedling downward by the action of the spring 40 and transplants it. Then, the 2 attached to the rotating case 29
If there is a difference in the amount of seedlings divided by the seedling transplanting claws 36, 36 of the base transplanting tool 35 or the seedling transplanting posture is poor, the transplanting device main body 35a is rotationally adjusted with respect to the transplanting device drive shaft 34, The size and angle at which the seedling transfer nail 36 intervenes in the seedling division opening 27 may be adjusted. In this adjustment, bolt 4
It is sufficient to adjust the mounting angle between the mounting member 42 and the implanting device main body 35a by loosening the fitting 3, but since this adjustment can be performed outside the implanting device main body 35a, the operation can be extremely easily performed. If the seedling-transplanting claws 36 are shifted laterally with respect to the seedling-dividing opening 27 of the seedling-receiving plate 26 at the time of dividing the seedlings, the cotter pin 44 is loosened and the transplanter body 35a is loosened.
May be adjusted in the axial direction by driving the cotter pin 44 again. Then, the connecting member 60 is also rotated by the rotation of the rotating case 29 by the seedling transplanting operation, and the feeding roll 52 of the fertilizer feeding section 49 is rotated via the connecting rod 65, the arm 67, and the one-way clutch, and the fertilizer is moved into the fertilizer transfer section 50. To fall. On the other hand, even if the driving rotary disk 58 rotates via the transmission belt 74 and the driven pulley 71 and the straw or the like floats on the field, the straw is properly embedded in the soil to form a groove on the soil surface. Since the fertilizer is formed, the fertilizer that has fallen in the fertilizer transfer unit 50 is properly applied in the groove, and is always applied to an appropriate uniform depth. Then, the fertilized grooves are backfilled with the earth covering plate 75, and the soil surface is flattened. However, fertilizer application is performed simultaneously with seedling transplantation. In particular, the connecting member 60 provided between the outer portions of the plurality of transplanting tools 35 provided on the rotating case 29 of the transplanting device 21 is connected to the fertilizer feeding section 4.
9 is provided, a driving member 64 for driving each implant 3 is provided.
5 and 35 are linked by a linking member 60 to perform a smooth operation and to perform good planting of seedlings.
Is used to drive the fertilizer feeding section 49 of the fertilizer application device 46, so that the fertilizer feeding section 49 can be smoothly driven with a simple structure. Further, the plurality of transplanting tools 3 of the rotating case 29
By disposing the groove generator 51 on the side opposite to the side on which the gears 5 and 35 are provided, the rotating case 29
And a plurality of implanters 35 provided on the rotating case 29.
Since the driving member 64 and the groove generator 51 provided on the connecting member 60 can be arranged within a narrow left-right width, the groove generator 5 can be positioned at the lateral position of the implanting tool 35 without largely shifting the position in the longitudinal direction of the body.
1 can be arranged, and even if the body is slightly meandering, the right and left distance between the seedling planting position and the fertilizing position by the transplant tool 35 is properly maintained, so that good fertilizing operation and seedling transplanting operation can be performed. In the above embodiment, only one of the disks 58, 59 of the groove generator 51 is provided for driving rotation, but both the disks 58, 59 are driven and rotated by the rotating case 29. May be provided.
