The multi-cutter (64) is moved up and down in conjunction with the up-and-down movement of the planting claw (50) to drill a planting hole in the multi-sheet.

Further, a pivot (7) is attached to the mounting plate (66).
1) and the cultivation roller (7) through the support arm (72).
3), a swing arm (76) for slidingly contacting a rotor (75) with a cam (74) attached to the drive shaft (53) through a swing plate (77) and a rod (78). And the cultivation roller (73) is moved up and down in conjunction with the up and down movement of the planting claw (50) to cultivate the seedling immediately after planting. ing.

By the way, the upper link (21) proximal pivot (21a) of the transplant frame (16) is provided with a potentiometer type detecting a relative position change between the transplant frame (16) and the implanting device (15). A transplanting frame (16) having a planting depth sensor (79) and changing the height of the ridge (A)
When the planting device (15) changes more than the setting, the raising / lowering cylinder (23) is controlled to expand and contract, and the planting device (15)
Is configured to be maintained within the setting.

This embodiment is constructed as described above, and while the worker is traveling on the traveling vehicle (1), the transplanting part (12) automatically moves the seedling tray (26) from the seedling tray (26).
A planting operation is carried out in which pot seedlings of the plant are taken out with the seedling take-out nails (43) and planted at regular intervals on the upper surface of the ridge (A) by the planting nails (50).

In this configuration, the weight changing portion such as the spare seedling mounting table (7), which has a large weight and large fluctuation, and a water tank (11) necessary for live use at the time of transplantation, is provided on the machine side. Then, the seedling supply device (13) and the seedling removal device (14), which are relatively heavy, are fixed to the vehicle body cover (9) and the three-point link mechanism (1
9), the hydraulic cylinder is controlled by a lifting cylinder (23), and only the planting device (15) is supported by the parallel links (21) and (22) so as to be able to move up and down. The tracing control is performed by following the upper surface of the ridges (A), and the lifting and lowering control by the lifting and lowering cylinders (23) is performed without giving the adverse effect of the weight fluctuation units (7) and (11) to the transplanting unit (12) side. The planting depth control is performed smoothly and with high precision by controlling the double structure of the profiling control using the gauge wheel (25).
In this case, by reducing the weight of the copying portion only to the planting device (15), accurate copying control is performed, and the unevenness of the upper surface of the ridge (A) formed by the gauge wheel (25) is also reduced. In addition, since running resistance can be reduced, dragging of the multi-seat can be reduced, and high-precision and good transplantation can be performed.
