Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grafting apparatus for automatically joining the cotyledon side of one rooted seedling, which is a rootstock, to the other rooted seedling of two different types of seedlings. It is.

[0002]

2. Description of the Related Art In the seedling raising process of fruit vegetables, there is a method called grafting in which the cotyledon side of a target seedling called a scion is joined to a rooted seedling called a rootstock.

[0003] As a conventional graft, for example, an operator cuts off one cotyledon formed on the top of a rootstock of a stock, and aligns the cut surface of the stem of a scion cut off diagonally with this cut surface. A method of fixing with a clip is known.

[0004] As another method of grafting, an operator similarly joins a stalk of an inclined cutting to a part from which one cotyledon of the rootstock has been cut using an instant adhesive. Methods are known.

[0005]

However, in any of the above-mentioned conventional grafting methods, in either case, one cotyledon of the rootstock is cut off, and the stem of the scion is clipped to this using a clip or an instant adhesive. It relies on human tactics that employ a large number of workers. As a result, there was a problem that workability of the graft was poor and productivity was poor.

In practice, the number of trees that can be grafted by one worker is limited to about 1,000 for 6 hours of work per day.

[0007] There are also problems with the grafted seedling itself produced by the conventional method. In other words, since one cotyledon of the rootstock has been cut off, the uptake of nutrients is poor.For example, in the case of cucumber seedlings, the growth is slowed down for about a week, and the resulting vegetables are generally of low quality with no gloss There was a problem that it was easy to become.

[0008]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a scion line for feeding a plurality of scions and a function for drilling a connecting hole in the headstock of the stock to provide a plurality of stands. By providing a stock line that feeds trees and a joining line that is provided between the two lines and performs grafting work, the splint on the scion line is automatically connected to the stand on the stock line by the joining line. A graft was made by piercing the graft hole of the tree's head. Moreover, since two cotyledons remain on the rootstock of the rootstock, the nutrients can be sucked up well, and the damaged portion of the rootstock becomes small, so that a relatively fast-growing grafted seedling can be produced.

According to the present invention, the following effects can be obtained.

That is, in the grafting device according to the first aspect of the present invention, the scion line, the stock line capable of forming a graft hole in the root of the stock, and the joining line provided between the two lines. With this arrangement, the splint on the scion line can be automatically stabbed into the graft hole of the headstock on the stock line by the joining line to be grafted. At this time, since two cotyledons are left on the rootstock of the rootstock, the nutrients are sucked up well, and the damaged part of the rootstock is small, so that relatively grafted and strong grafted seedlings can be produced. .

In particular, in the grafting device according to the second aspect, in addition to the effect according to the first aspect, the scions being transferred by the scion line are picked up one by one by the scion transferring means. Move sequentially to the corresponding stock on the stock line,
Since the stem of each ear tree is cut into a sharp wedge by the cutting means, the stem can be smoothly inserted into the joint hole.

Furthermore, since the cut surface to be joined is large and clean and the surrounding cell tissue is hard to be broken, the rootstock and the scion are joined quickly, and the nutrients can be sucked from the stock to the scion.

The grafting device according to the third aspect of the present invention has the effect of the first or second aspect, and in addition to the effect of the first aspect,
In each of the rootstocks on the rootstock line, diagonal piercing holes were made in the stem meat using drilling pins, avoiding the captive tube inside the stems. If pierced, the scion will be able to avoid the captive tube and be surely in contact with the stem of the rootstock. Therefore, it is possible to prevent a problem that the roots grown from the scion after the grafting extend in the captive tube and consequently the grafting is not performed.

Further, the grafting device according to claim 4 is
In addition to the effects of claims 1 to 3, the coordinates of the cutting tip of the scion being moved are detected by the joint line coordinate detecting means, and the rootstock position correcting means is then corrected by the rootstock position correcting means based on the detected coordinates. Is performed, the stems of each ear tree can be accurately inserted into the corresponding hole of the root tree on the root line.

The grafting device according to claim 5 is
Using the scion transfer means of the joining line, pick the scions of the scion pallets being fed by the scion line one by one and move them to the corresponding stock of the stock pallets on the stock line. At the same time, in the stock line, using a piercing means, in the feedstock of the corresponding stock of the stock pallet, avoiding the captive tube in the stem and piercing the joint hole with a piercing pin. Therefore, a reliable graft can be obtained as described above.

[0092] Further, since the stem of the scion is cut into a sharp wedge by the cutting means during the movement of the scion by the scion transferring means, the stem can be smoothly inserted into the joint hole. Since the cut surface to be joined is large and clean, and it is difficult to break the surrounding cell tissue, the effect of fast connection between the stock and the scion and good suction of nutrients from the stock to the scion can be obtained. .

Thereafter, the coordinates of the cutting tip of the scion in the middle of the movement are detected by the joining line coordinate detecting means, and the stock position correction is performed by the stock position correcting means based on the detected coordinates. , Then the stems of each scion,
Grafting can be performed exactly at the corresponding grafting hole on the rootstock line.

Then, the scion is lowered on the stock line by the scion transferring means, and the cut stem is pierced into the grafting hole of the head adoption so as to be grafted. I can do it.

Also, when grafting, 2
Since the leaves of the cotyledons are left, the uptake of nutrients from the roots is good, and the only part that damages the rootstock is the head that is near the base of the cotyledon where the grafting hole is drilled. The damaged area is small, the rootstock grows quickly, and strong seedlings can be produced.
