DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention holds a scion seedling of a grafting machine, cuts it, and transfers it to a predetermined position. The present invention relates to a scion seedling holding device that receives and fixes the hypocotyl when cutting a predetermined position of the hypocotyl of the scion.

[0002]

2. Description of the Related Art A scion seedling having a hypocotyl sandwiched by a scion holding piece is transferred to a predetermined position to cut a predetermined position of the hypocotyl, and the cut scion seedling is transferred to a predetermined position. Then, the cut portion of the scion seedling hypocotyl is joined to the cut portion of the stock seedling hypocotyl, and the joined portion is held by the clip to complete the grafting.

[0003]

At the time of cutting a predetermined position of the scion seedling hypocotyl, the hypocotyl is not received and fixed, so that it escapes in the cutting direction. If the length of the cut becomes unstable or the spikelet seedling hypocotyl is bent, problems such as shifting of the cutting position may occur, and the survival rate of grafted seedlings may decrease. The present invention is intended to solve these problems.

[0004]

For this purpose, the present invention relates to a cutting part (E) of a rootstock seedling (A), a cutting part (E) of a hypocotyl (C), and a cutting part (B) of a hypocotyl seedling (B). F) and a clipping machine that holds the clip 5 with the clip 5. The scion clipping piece 38 which clamps the hypocotyl (D) portion of the scion seedling (B), cuts and transfers it, and the scion. The structure of the scion seedling fixing device of the grafting machine, characterized in that a backrest fixing plate 45 having a convex portion 49 for receiving and fixing the hypocotyl (D) portion is provided below the tree holding piece 38. I do.

[0005]

A predetermined position of the scion seedling (B) hypocotyl (D) is clamped by the graft clamping pieces 38, 38.
8 The back side in the cutting direction of the hypocotyl (D) portion is fixed by the backrest fixing plate 45 provided on the lower side, and both sides of the hypocotyl (D) portion are convex portions 49 provided on the backrest fixing plate 45. , 49 are fixed in a sandwiched state, transferred to a predetermined position, the predetermined position of the hypocotyl (D) portion is cut, and the cut scion seedling (B) is transferred to a predetermined position, and B) The cut portion (F) of the hypocotyl (D) portion is joined to the cut portion (E) of the stock (A) hypocotyl (C) portion, and the joined portion is held by the clip 5 to complete the grafting. I do.

[0006]

According to the present invention, when cutting the seedling (B) hypocotyl (D), the hypocotyl (D) is clamped by the scion clamping pieces 38, 38 and By being fixed between the convex portions 49 of the backrest fixing plate 45, the hypocotyl (D) does not escape in the cutting direction, and the length of the cut is always constant. Even if the hypocotyl (D) portion is bent, the hypocotyl (D) portion is in an extended state by being fixed in a sandwiched state between the convex portions 49, 49 of the backrest fixing plate 45. The cutting position does not shift, and the cutting position is stabilized. With these, the survival rate of grafted seedlings can be improved.
