駆動軸13,13を間歇駆動させる。Next, the operation of the present invention configured as described above will be described. When transplanted to the upper surface of the ridge of the pot seedling, the inter-strain detection limit switch (not shown) is detected along with the forward movement of the machine body 1, and the solenoid 57 is controlled based on the inter-strain detection signal by the switch. The spring clutch 48a is intermittently operated to intermittently drive the drive shafts 13, 13 of the planted pawl drive case 12.

勢を維持しながら長円軌跡を移動するのである。As the drive shafts 13 and 13 are driven and rotated, the rotor cases 14 and 14 rotate, whereby the driven teeth 18 and 18 connected to the fixed teeth 15 and 15 via the chains 19 and 19, respectively. Rotates around the fixed tooth bodies 15 and 15 while revolving, and the eccentric shaft portions 17 and 17 of the driven shafts 16 and 16 move up and down in a long axis elliptical locus,
As a result, the graft claw 11 moves along the elliptical locus while maintaining the vertical posture together with the support member 20.

It is received inside the transplanted nail 11.

Therefore, when the seedling is transferred from the lower end of the conveyor belt 9a 9a of the seedling transfer guide device 9 to the transplant nail 11, the posture of the seedling is not disturbed, and the root portion of the seedling is kept in the lower position. The seedlings can be delivered within 11.

a opens to discharge the pot seedlings in the transplanted nail 11 into the soil, and after the end of planting in which the pot seedlings in the transplanted nail 11 have been discharged, the transplanted nail 11 reaches the top dead center position. When moved, the split transplant claws 11a, 11 are caused by contact between the rollers 22, 22 and the narrow portions on both end surfaces of the cam 24.
a is closed.

悪くなるのを防止できるのでのである。During the work of transplanting the ridges by the transplanted nail 11, the transplanted nail drive unit 12 always precedes the transplanted nail 11, and thus the seedlings transplanted by the transplanted nail 11 are driven by the transplanted nail. This is because it is possible to prevent the part 12 from interfering with the planting posture of the seedlings.

2, the transplanting claw 11 is disposed behind the drive unit 12 in the advancing direction of the transplanting machine to support the transplanting claw 11 so as to be drivable along the planting track, and to receive the seedling in the planting track of the transplanting claw 11. Since the guide drop end portion of the seedling receiving and guiding device 9 that receives and guides the seedlings supplied from the seedling feeding device to the transplant nail 11 is located above the position, the transplant nail driving portion 12 is provided.
Is always preceded by the transplanted nail 11 to prevent the transplanted nail drive part 12 from interfering with the seedlings transplanted by the transplanted nail 11 to deteriorate the seedling planting posture. The seedling can be done well.
