れる。Next, explaining the operation of the example of transplanting the vegetable seedlings A into the ridges B laid with the multi-film C, the left and right driving front wheels 19 and 20 and the rear wheels 14 and 15 of the riding type seedling transplanter are arranged in the ridges D in the field. Set the machine so that it is positioned, and put a pot-shaped vegetable seedling A on the seedling stand 3.
After storing and housing the engine, start the engine 12
At 69, the seedling transplanting work machines 4 and 4 are lowered to the transplanting work position to be in an automatic control state, and the seedling placement table 3 and the seedling planting device 42 are operated by the transplantation clutch lever 68 to advance the machine body.
Since the seedling placing table 3 is reciprocally rocked in the left-right direction via the left-right drive mechanism, the seedling A located on the rear end side is moved to the left and right while being received by the seedling receiving frame 32, to the seedling take-out port 34. The seedling A is fed out and grasped by the seedlings 42b and 42c that draw the seedling locus P, and moves downward to pierce the mulch film C, and the seedlings 42b and 42c holding the seedling in the ridge B plunge. , Seedlings
42b and 42c are separated from each other to release the seedling A, and from the moment the seedling A is released, the seedling pushing tool 42d moves downward at the same speed as the seedling planting claws 42b and 42c move upward, and the seedling A is moved there. Place it in (P 1 ) and transplant. Further, since the seedling transplanting work machines 4 and 4 are both vertically controlled so as to always be in the proper position with respect to the ridge B, the seedling transplanting depth is always in an appropriate state. In addition, while the left and right presser plates 54, 54 of the pressurizing device 45 move downward from above the mulch film C on both sides of the transplanted seedling A and press in the direction of the seedling A, while bringing soil to the seedling A. Since the pressure is suppressed, the seedling A is reliably transplanted. At this time, the aircraft is moving forward even while the left and right presser plates 54, 54 are moving downward and pressing in the direction of the seedling A, but the shaft 52 pits against the tensile force of the tension spring 57 to form a long hole. Since 56 is moved, the left and right compression plates 54, 54 do not move while the mulch film C is being pressed, and the mulch film C is not scratched and broken, and good planting work is performed.

る。And, in particular, the left and right front wheels 19 traveling in the furrow D of the field.
In a riding type seedling transplanter in which a riding type traveling vehicle body 1 having 20 and left and right rear wheels 14 and 15 is vertically movable via a link mechanism 2, a riding type seedling transplanting machine is mounted on the seedling transplanting working machine 4. The seedling planting device 3 is provided on the side of the model traveling vehicle 1 in a slightly inclined state and reciprocates left and right, and a seedling planting device 42 for taking out one seedling from the rear end side of the seedling placing base 3 and planting it in a field 42 The ridge height sensor 66, which is in contact with the upper surface of the ridge B near the front of the seedling planting position P 1 of the seedling planting device 42, detects the position of the ridge B upper surface by the ridge height sensor 66 so that the seedling planting device 42 has a predetermined planting depth in the ridge B. Since the link mechanism 2 is vertically moved by the drive actuator 21 so as to plant seedlings, a control mechanism for controlling the vertical position of the seedling transplanting working machine 4 is provided.
And, since the seedling planting device 42 always controls the vertical position of the seedling transplanting work machine 4 so that the seedling planting device 42 always plants the seedlings in the ridge B at a predetermined planting depth in the riding type traveling vehicle body 1 having the left and right rear wheels 14 and 15. Appropriate seedling transplanting work can be performed, and the seedlings after transplantation will grow smoothly because the planting depth is appropriate. Further, the seedling transplanting work machine 4 is provided with a slightly elevated slope on the side of the riding type vehicle body 1 and reciprocally moves left and right, and a seedling mount 3 is provided from the rear end side of the seedling mount 3. Since the seedling planting device 42 for taking out and planting in the field is provided, the whole length of the machine can be shortened, and since the seedling placing table 3 is provided in a gently inclined state, the seedling placing table 3 is provided. The operator can easily confirm the state of the seedlings placed on the plant and the operating state of the seedling planting device 42 located at the rear of the plant from the riding type traveling vehicle body 1 so that troubles can be found immediately and the work efficiency can be improved. Good seedling transplant work can be done.
