Therefore, the construction is such that the grafting operation can be performed efficiently. Hereinafter, the operation of the above embodiment will be described.

When grafting the seedlings by the grafting machine 1, the operator moves the speed setting knob 54 of the operating device 9 to a predetermined position on both the front and rear sides of the machine frame 2 in accordance with the worker's ability to supply seedlings. By setting the grafting process interval time, the rootstock seedlings of the rootstock seedlings and spikelet seedlings are inserted and supplied to the seedling receiving frame 14a of the rootstock seedling support frame 10a of the grafting mechanism 7a by one worker. In addition, the scion seedlings are the scion seedling support frame 1 of the grafting mechanism 7b.
0b is inserted and supplied to the seedling receiving frame 14b by the operator on the other side, and by operating the start means 22, the ON input of this operation and the rootstock seedling sensor 19a and the earling seedling sensor 19b are changed to the rootstock seedling and the earling. When a predetermined time until the start of the grafting process set above elapses due to the seedling detection input, the grafting machine 1 starts.

The hand portions 28, 32 of the rootstock seedling grafting device 11a and the earling seedling grafting device 11b of the grafting mechanisms 7a, 7b.
Then, the rootstock seedlings and spikelets supported by the seedling receiving frames 14a, 14b for rootstock seedlings and spikelets are taken over, swiveled to a predetermined position and stopped, and the rootstock seedlings are cotyledon support plates. 29, the hand part 28 is opened, the hand part 28 is opened, the rootstock seedling descends to a predetermined position by the discharged air, and is again held by the hand part 28, and at the same time, the cotyledon on one side of the rootstock seedling is cotyledon pressing plate. 30 descends and holds down.

The cutting blade 43a of the cutting mechanism 8a rotates upward from below, leaving the cotyledon and the rooted stem on the side holding the cotyledon of the rootstock seedling and leaving the cotyledon and the true leaf (bud) on the other side in a predetermined manner. Cut diagonally from the depth position, one cotyledon and root stem remain. Cutting mechanism 8
The cutting blade 43b of b rotates from top to bottom, and cuts obliquely at predetermined positions of the lower stems of both cotyledons and true leaves (buds) of the seedlings. ) And part of the stem remain. The rootstock seedling grafting device 11a and the scion seedling grafting device 11b rotate and move to a predetermined position, and the cut portions of the cut rootstock seedling and the scion seedling are joined.

The clip accommodated in the storage tank 47 of the clip storage device 5 is swingably transferred from the storage tank 47 to the transfer passage tube (A) 48 with the clip holding portion closed, and stopped at the terminal end. When the clip pusher 52 pushes the center of the clip, the transfer passage cylinder (B) 49 is sequentially changed from the closed state to the open state with the clip holding portion being closed.
Further, the opening / closing plates 51, 51 are pushed out to the junction of the seedlings in an open state and stopped, and the opening / closing plates 51, 51 are operated to the open state, the clip holding portion is closed, and the junction of the seedlings is closed. When the grafting is completed, the grafted seedlings are pushed out to a predetermined position by the clip pusher 52, and the grafted seedlings are discharged onto the lower transfer conveyor.

When the start means 22 is turned ON and this ON is inputted, the rootstock seedling sensor 19a and the spikelet seedling sensor 19b do not detect the rootstock seedling and the spikelet seedling. When the detection is not input, the rootstock seedlings / spikelet seedling grafting devices 11a and 11b operate to move the rootstock seedlings / supplementary seedlings to the joining position where the cut rootstock seedlings and the spikelet seedlings are joined. The devices 11a and 11b are rotated and stopped, and the rootstock seedling sensor 19a and the spikelet seedling sensor 19b detect the rootstock seedling and the spikelet seedling and control the apparatus to be in a standby state at the joining position until input. Stop being being. When the detection of rootstock seedlings and spikelets is input during this standby, the rootstock seedlings and spikelet seedling grafting devices 11a and 11b are used to take over these rootstock seedlings and spikelet seedlings. Rotates.
