DESCRIPTION OF THE PREFERRED EMBODIMENTS A transplanting machine according to the present invention pivotally supports the base ends of a pair of left and right implanted nail forming bodies, and opens and closes the distal end sides of the two implanted nail forming bodies so as to separate and contact with each other. A planting claw that can be planted by holding a potted seedling between the side walls of both planted claw forming bodies in contact with each other, and a seedling that prevents the potted plant from adhering to the planted claw An adhesion preventing means is provided.

[0007] The seedling adhesion preventing means forms an adhesion preventing piece insertion hole in a side wall of each planted nail forming body, and arranges the adhesion preventing piece outside each adhesion preventing piece inserting hole, respectively. At the time of opening operation of the formed body, the tip of the anti-adhesion piece is inserted between the side walls of the both-planted nail forming body through each of the anti-adhesion piece insertion holes, and both of the anti-adhesion pieces put the root pot of the pot seedling into the both-planted nail It is configured to push in a direction away from the side wall of the formed body.

According to such a seedling adhesion preventing means, even if the root pot portion of the pot seedling is likely to adhere to one of the planted nail forming bodies during the opening operation of each planted nail forming body, The seedling can be pushed away from the side wall of the planted nail forming body by the insertion portion of the adhesion preventing piece to separate the pot seedling from the planted nail forming body.

In particular, since a structure for preventing the attachment of the potted seedling to each planted nail forming body is provided, the potted seedling can be reliably separated from each planted nail forming body, and the root pot portion of the potted seedling can be removed. Adhesion to the side wall of each planted nail forming body can be reliably prevented.

In addition, instead of providing the adhesion preventing piece insertion hole and the adhesion preventing piece, elasticity is provided between the side walls of the pair of left and right planting claw formations in a direction substantially orthogonal to the opening and closing direction of the both planting claw formations. A biased anti-adhesion body is provided, and the pot seedling is clamped against the elastic biasing force of the anti-adhesion body by the closing operation of the pair of left and right planted nail forming bodies, while the opening operation of both planted nail forming bodies is performed. Thus, the potted seedling can be released from being pinched, and the potted seedling can be pushed by the elastic urging force of the adhesion preventing body in a direction away from the side walls of the both-planted claw forming members, thereby forming seedling adhesion preventing means.

According to the seedling preventing means, the strain generated in the anti-adhesion body during the closing operation of the two-planted nail forming body is released at the time of the opening operation of the two-planted nail forming body, and Since the pot seedling can be reliably separated from the body, the root pot portion of the pot seedling does not adhere to the side wall of each planted nail forming body.

In particular, since the antiadhesive body is interposed between the two-planted nail forming body and the potted seedling sandwiched between the two-planted nail forming bodies, the potted seedling adheres to the two-planted nail forming body. Can be prevented, and the potted seedling can be more smoothly separated from the both-planted nail-forming body.
