Abstract

PROBLEM TO BE SOLVED: To provide the scion seedling reception device of the grafting machine with a superior taking rate and operability which has an insertion groove for holding the small-diameter side of a hypocotyl with a clip made narrower than the large-diameter part of the hypocotyl and makes it secure to hold it with the clip and is inserted always by facing to a certain direction. SOLUTION: The grafting machine which reholds and clamps a scion A inserted into and held in the insertion groove 24 of a holding plate 23, joins the cut end of the hypocotyl E of the scion A cut and separated with a scion cutting knife, and holds it with the clip is so constituted that the groove width 25 of the insertion groove 24 for holding the small-diameter side of the hypocotyl E sectioned in an elliptic shape is made less than the width of the large-diameter part M of the hypocotyl.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scion seedling receiving device for a grafting machine.

[0002]

2. Description of the Related Art A cross section of a scion into an insertion groove of a holding plate is inserted into the insertion groove by an operator regardless of the large and small diameter directions of the elliptical hypocotyl portion. The scion is held by a holding plate, and this scion is held by a scoop holding piece, and a scissor cutting knife cuts a predetermined position of the scion embryo shank. The cut end and the rootstock are joined, and the joined portion is held by the clip to complete the grafting.

[0003]

[Problems to be Solved by the Invention] The scion hypocotyl is inserted into the insertion groove of the holding plate and held by this holding plate. By inserting regardless of the large diameter and the small diameter of the, when joining with the clip, the large diameter side of the hypocotyl part may be pinched with the clip on the side with a small contact area. , The contact area between the clip and the hypocotyl part was reduced, and the joint part was not reliably picked, so that the grafting was not performed in some cases. This is solved by constantly inserting the material in the direction of the large diameter.

[0004]

To this end, according to the present invention, the scion A, which is inserted into and held in the insertion groove 24 of the holding plate 23, is held by the scion holding piece 38 while being held. In the grafting machine in which the cut C of the hypocotyl A hypocotyl E part that has been cut and separated by 42 is joined to the rootstock D and held by the clip 5, the small diameter N side of the hypocotyl E having an elliptical cross-sectional shape is the clip. In order to hold at 5, the groove width 25 of the insertion groove 24 is set to be smaller than the large diameter M portion of the hypocotyl E to form a scion seedling receiving device of a grafting machine.

[0005]

The groove width 25 of the insertion groove 24 of the holding plate 23 is smaller than that of the large diameter M portion of the elliptical cross-sectional shape of the scion A embryonic axis portion E. When the person inserts the scion A hypocotyl E part toward the large diameter M direction of the hypocotyl E part, the scoop A is held by the holding plate 23,
Is gripped by the scoop holding piece 38, cut at a predetermined position of the scion A hypocotyl E part by the scissor cutting knife 42, and the cut C and rootstock D of the cut scoop A hypocotyl E part are cut. Are joined together, hypocotyl E
The small diameter N side is held by the clip 5, and the grafting ends.

[0006]

[Effects of the Invention] Since the groove width 25 of the insertion groove 24 of the retaining plate 23 for inserting the hypocotyl A part of the scion A is made smaller than the large diameter M part of this hypocotyl E part, the scion A The hypocotyl E part cannot be inserted unless it is directed in a fixed direction, that is, the direction of the large diameter M. The hypocotyl E part is always inserted in a fixed direction, and the clip 5 is not held. By holding the small diameter N side of the hypocotyl E part, the contact area between the clip 5 and the hypocotyl E part is increased,
It will be held securely with this clip 5,
A good graft can be obtained.
