It is rotatably supported by bearing members 30 and 30 provided integrally with the vertical pipe 5 and the planting portion transmission case 6.

Further, on the upper part of the body, a seedling stand 31 is supported by a support frame 32 and rails 33 so as to be slidable in the left-right direction, and the seedling stand 31 is slightly tilted so that the front part is at the top. This seedling mounting stand 31 is partitioned into two seedling mounting sections 31a, 31a, and each seedling mounting section is provided with a seedling feeding belt 36 stretched between a pair of rollers 34, 35. Further, a receiving plate 39 on which seedling take-out holes 38 and 38 corresponding to the seedling trays 31a and 31a are formed is provided adjacent to the rear end of the seedling tray 31 and fixed to the machine frame side.

The lateral movement mechanism of the seedling table 31 includes a horizontal lead cam shaft 41 having clockwise and counterclockwise lead grooves formed on its outer circumferential surface, and a lead fixed to the bottom surface of the seedling table 31 and engaged with the lead grooves. A member 42 is provided. When the lead cam shaft 41 is rotated in a predetermined direction by being driven from the planting unit mission case 7 via the transmission means in the seedling platform drive case 43, the seedling platform 31 reciprocates in the left and right direction, and the seedling platform 31a
.

The seedlings in the last row on 31a are sequentially supplied to seedling take-out ports 38 and 38. When the seedling platform 31 moves to the end of the left and right stroke, the seedling feeding belt 36°36 rotates in a predetermined direction by a predetermined amount to transfer the seedlings backward by one row.

The transplant device @23 includes a first rotating case 51 that is rotatable with respect to the transplant device transmission case 22, a second rotating case 52 that is rotatable with respect to the first rotating case, and a transplant that is freely rotatable with respect to the second rotating case. A case 53 is provided, and a transplant case 53 is provided.
A pair of transplant claws 55° 55 and a seedling pusher 56 are provided. The position of the transplant claw 55.55 of each transplant device corresponds to the position of the seedling extraction port 38.38. By rotating the first rotation case 51 and the second rotation case 52 at a predetermined rotation ratio, the transplanted nail 55.55 is maintained in a constant posture and moves up and down in a closed loop while drawing a predetermined trajectory. At the upper part, the transplanting claws 55° 55 clamp the seedlings supplied to the seedling take-out port 38, and at the lower part of the trajectory, the seedlings are transplanted to the field. Immediately after transplantation, the seedling pusher 56 protrudes to prevent the seedling from being lifted up by the transplanting claws 55 and 55.

Note that the rear part of the transplant device @23, 23 is connected to the bearing member 30.
．． It is covered with a cover 58 that is supported by cover support plates 57, 57 attached to 30.
