Description

Detailed Description of the Invention

[0001]

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

[0002]

Conventionally, a rootstock seedling support frame that supports supplied rootstock seedlings, a rootstock seedling support frame that supports supplied rootstock seedlings, and these rootstock seedlings and rootstock seedlings that are supported , Each grafting mechanism rotates and moves to a predetermined position and stops, and the rootstock seedling leaves the cotyledon and rooted stem on one side, and cuts the cotyledon and the true leaf (bud) on the other side by the cutting mechanism. By rotating the blade from the bottom to the top, it is cut diagonally from the predetermined position,
In addition, the scion seedling is cut diagonally from a predetermined position by rotating the rooted stem from the upper part to the lower part, leaving the cotyledon and the true leaf (bud) on both sides, The cut portion between the rootstock seedling and the scion seedling is joined, and the joined portion is pinched with a clip or the like to complete the grafting. As described above, the cutting of rootstock seedlings was performed by the cutting device that rotates from the bottom to the top.

[0003]

The rootstock seedlings supplied to the rootstock seedling support frame of the grafting machine are supported by this rootstock seedling support frame, and the rootstock seedlings supplied to the rootstock seedling support frame are , Supported by this scion seedling support frame, these rootstock seedlings and scion seedlings are taken over by each grafting mechanism, and pivotally moved to a predetermined position to stop.
The rootstock seedling leaves the cotyledons and rooted stems on one side, and leaves the cotyledons and true leaves (buds) on the other side, and the cutting blade of the cutting mechanism rotates from the lower part to the upper part, so The stem is cut into the state, and the cotyledon seedlings have cotyledons and true leaves (buds) on both sides.
With the exception of, the cutting blade of the cutting mechanism for rooted stems is rotated from the upper part to the lower part, so that the stems are cut in an oblique state from the predetermined position, and these grafting mechanisms are rotated to the predetermined position and stopped. The cut portions of the cut rootstock seedlings and the scion seedlings are joined, and the joined portions are pinched by a clip or the like to end the grafting work and stop.

When cutting one-sided cotyledons of the above rootstock seedlings, the rooted stems are rounded up from diagonally downward to upward so that the cotyledon expansion angle is small or the true leaves (buds) grow large. In rootstock seedlings, it was difficult to cut with a cutting blade, which sometimes resulted in shallow cutting or frequent occurrence of part of the true leaves, resulting in poor grafting performance. .

[0005]

The present invention is directed to a rootstock seedling support frame 9 for supporting rootstock seedlings, a scion seedling support frame 10 for supporting scion seedlings, the rootstock seedlings and the scion supported. In a grafting machine provided with a cutting mechanism 12 for cutting and grafting seedlings, a grafting mechanism 11, one side cotyledon and a true leaf (bud) of the upper end of the rootstock seedling supported by the rootstock seedling support frame 9 And a cutting blade 35 of the cutting mechanism 12 in an oblique state from the upper part to the lower part.

[0006]

The rootstock seedlings supplied to the rootstock seedling support frame 9 of the grafting machine are supported by the rootstock seedling support frame 9, and the rootstock seedlings supplied to the rootstock seedling support frame 10 are: This scion seedling support frame 10
These rootstock seedlings and scion seedlings are supported by each grafting mechanism 1
1 and 11 take over and hold, pivotally move to a predetermined position and stop, and the rootstock seedling leaves the cotyledons and rooted stems on one side, and cuts cotyledons and true leaves (buds) on the other side. 12 cutting blades 35
Is rotated from the upper part to the lower part, the stem is cut obliquely from a predetermined position, and the scion seedling has a mechanism for cutting a rooted stem, leaving cotyledons and true leaves (buds) on both sides. By rotating the cutting blade 35 'from the upper part to the lower part, the stem is cut obliquely from a predetermined position, and these grafting mechanisms 11 and 11 pivotally move to the predetermined position and stop. The cut portion between the tree seedling and the scion seedling is joined, and the joined portion is pinched by a clip or the like to end the grafting work and stop.

[0007]

EFFECTS OF THE INVENTION In the rootstock seedling, the cutting blade 35 of the cutting mechanism 12 is rotated from the upper part to the lower part to be cut,
The true leaves (buds) were surely removed, and the shallow cutting was eliminated, and the joining condition of the joining part was improved, and the grafting performance between the rootstock seedling and the scion seedling could be improved.

The configuration is such that stop control and adjustment control are performed. Less than,
The operation of the above embodiment will be described. When seedlings are grafted by the grafting machine 1, the interval setting knob 39 of the operating device 8 is operated to a predetermined position according to the operator's seedling supply capacity, and the rootstock seedlings are inserted into the rootstock seedling support frame 9. By supplying the sapling seedlings to the sapling seedling support frame 10 and operating the start switch 40, this operation and the rootset seedling and sapling seedling detection inputs of the rootstock seedling sensor and the seedling seedling sensor are performed. According to the above, the grafting machine 1 is started when a predetermined time until the start of the grafting step set above has elapsed.

Grafting mechanism 11,1 for rootstock seedlings and scion seedlings
With the hand parts 25 and 25 'of 1, the rootstock seedlings and the spikelet seedlings supported by the rootstock seedling support frame 9 and the spikelet seedling support frame 10 are taken over, and rotated to a predetermined position and stopped. However, only the rootstock seedling is supported by the cotyledon support plate 26 in a hanging state, the hand portion 25 is opened, and the rootstock seedling is lowered to a predetermined position by the air to be ejected and held by the hand portion 25 again at the same time. The cotyledon pressing plate 27 descends and presses the cotyledon on one side of the rootstock seedling from above.

The cutting blade 35 of the cutting mechanism 12 for rootstock seedlings is
Rotate from the upper part to the lower part, the predetermined position on the lower side of the cotyledon of the rootstock seedling is obliquely cut, leaving one pressed cotyledon and rooted stem on one side, and one cotyledon on the other side And the true leaf (bud) are excised. Further, the cutting blade 35 'of the cutting mechanism 11 for cutting seedlings rotates from the upper part to the lower part, so that the predetermined positions on the lower side of both cotyledons of the scion seedling are slanted and both cotyledons and true leaves (buds).
The rooted stalks are cut off, leaving behind. The grafting mechanisms 11 and 11 rotate to move to a predetermined position, and the cut portions of the cut rootstock seedlings and the scion seedlings are brought into a joined state.

Clip storage tank 4 of clip storage section 5
The clip transferred from 9 through the clip transfer passage 6 is pushed out by the clip push-out tool 50, the joint is gripped by the clip, and the grafting is completed, and the clip is discharged to the lower part.
