(Problems to be solved by the invention) However, in the above-described conventional technique, the seedlings are allowed to naturally fall by the gravity of the seedling when the transplanted nail is opened.
Light weight seedlings and seedlings with high humidity may be caught or attached to the inner surface of the transplanted nail and may not fall naturally.If the seedlings do not fall like this, the planting is not successful. In addition, in some cases, the next seedling is received while the seedling is left in the transplanted nail, and it is impossible to plant two seedlings at the same time when the transplanted nail is planted. There was a problem that the planting condition was certain.

(Operation) With the above configuration, the transplanting nail (11) that receives the seedlings falling from above and is transplanted to the planting position starts opening according to the planting operation, and at the same time, the retainer (30) is pushed into the transplanting nail (11). By forcibly discharging the seedlings in the transplanted nail (11) by pushing out the pressing tool (30), the seedlings are caught in the transplanted nails (11) or adhered to the seedlings. It can be reliably discharged without being left in the transplanted nail (11), and by providing the push-out tool (30), the seedlings are reliably discharged even if the opening amount of the transplanted nail (11) is reduced. Since the hole formed in the soil by the transplanted nail (11) can be kept small, the planting posture of the seedlings dropped in the hole can be always stabilized.

(Effects of the Invention) The present invention receives a seedling falling from above and performs a planting operation by a pair of split implant claw pieces (11a) (11b) that can be opened and closed.
At the start of opening the bucket type transplanting nail (11) at the planting position, the bucket-like transplanting nail (11) is moved forward into the transplanting nail (11) to forcibly discharge the seedlings in the transplanting nail (11) and at the same time the planting is performed. Attached Claw (11)
During the ascending stroke from the end of planting seedlings to the start of opening at the next planting position, the presser foot (30) that returns to the outside from the planting claw (11) and the presser foot (30). The planted nail (1
By providing a reciprocating mechanism (40) for reciprocating with respect to 1), seedlings in the transplant nail (11) can be forcibly discharged at the planting position by using the retainer (30). Therefore, the seedlings can be reliably discharged without being caught in the transplanted nails (11) or adhered and left in the transplanted nails (11), and the seedlings are left in the transplanted nails (11). It is possible to eliminate the trouble of receiving the next seedling, and since the opening amount of the transplant nail (11) may be small by using the pressing tool (30), as a result, the transplant nail (11) By (), the holes formed in the soil can be made smaller, and thus the fallen seedlings can be prevented and the plants can be planted in a good planting posture.
