The rootstock seedlings and spikelets used for the production of grafted seedlings are diverse. There was also a problem that an optimum cutting depth could not be ensured for all kinds of seedlings.

The present invention has been made to solve both of these problems, and a first object of the present invention is to facilitate the adjustment of the relative position of each mechanism, thereby facilitating the assembly work and shortening the time. Another object of the present invention is to provide an apparatus for producing grafted seedlings in which the optimum cutting depth can be ensured according to various seedlings.

[0006]

In order to achieve the above object, the present invention has the following constitution.

According to the first aspect of the present invention, a rootstock seedling holder for holding rootstock seedlings, a rootstock transport mechanism for transporting rootstock seedlings, and a rootstock cutting mechanism for cutting rootstock seedlings are associated with each other. A scion seedling holder for holding scion seedlings, a scion conveyance mechanism for conveying scion seedlings, and a scion cutting mechanism for cutting scion seedlings are attached to each other at predetermined positions of the tree-side support member. Attachment is made to a predetermined position of the supporting member on the side of the spar, and an adhesive mechanism for bonding both cut surfaces of the stock and the scion is attached to the mounting member, and the two supporting members are attached to the respective transport mechanisms with respect to the adhesive mechanism. A grafting seedling manufacturing apparatus characterized in that the grafting seedling manufacturing apparatus is mounted on the mounting member with adjustment mechanisms for positioning the seedlings interposed therebetween.

According to a second aspect of the present invention, each of the cutting mechanisms is attached to a corresponding one of the supporting members via a cutting position adjusting mechanism that positions the cutting mechanism with respect to each of the transport mechanisms. An apparatus for producing a grafted seedling according to claim 1.

[0009]

In the grafting seedling manufacturing apparatus configured as described above, when seedlings serving as rootstocks are supplied one by one to the rootstock seedling holder, the rootstock transport mechanism grips the seedlings and transports them to the grafting position. On the other hand, when the seedlings to become the scions are supplied one by one to the scion seedling holder, the scion transport mechanism grasps the seedlings and transports them to the grafting position. Then, each seedling being transported by both transport mechanisms is cut at a predetermined portion by a corresponding cutting mechanism, and when the rootstock and spike come to the grafting position, both cut surfaces are bonded by an adhesive mechanism to produce grafted seedlings. I do.

According to the first aspect of the present invention, the relative positions of the bonding mechanism and the two transport mechanisms, which require fine adjustment, are adjusted by adjusting the adjusting mechanism of the stock side supporting member and the adjusting mechanism of the scion side supporting member. If so, the relationship between their relative positions can be adjusted. Even if this relative position adjustment is performed, the transport mechanism, the seedling holder, and the cutting mechanism are attached to each support member, and their relative positional relationship is maintained without any change. It is not necessary to readjust the part, and the adjustment becomes easy as a whole, so that the assembling work of the apparatus can be made smoother and shorter.
