A dial-type mode changeover switch 21 for selecting "manual", "automatic" and "sorting" operations, an operation switch 22 for selecting "start" and "stop", and a crop switch (watermelon in the embodiment) 23) a step switch 1 for performing cutting, feeding, joining and the like for each step, a reset switch 2 for returning the operation to an initial state,
A scion grasping force adjustment switch 24, an operating pressure gauge 25, and the like that can adjust the grasping pressure on the scion seedling before cutting are provided.

Reference numeral 26 denotes, for example, the transfer / supply speed of the scion seedlings 11 and the stock seedlings 13 by the scion seedling supply device 12 and the stock seedling supply device 14, the scion seedling cutting device 15 and the stock root cutting device 1
6 is a speed adjusting device for adjusting the cutting speed and the like of the scion seedlings 11 and the stocking seedlings 13 by using the control panel 6 near the operation panel 3 and provided with a cover 27 that can be opened and closed on the upper surface.

Therefore, since the operator can easily adjust the speed of each operation, the joining posture of the earling 11 and the stock 13 can be improved, and the joining rate can be increased. 28
Is a clip storage container of the clip supply device 10, and has a discharge hole 29 in a side surface portion of a rear end opposite to the joining side. A vertically long dust shutter 30 is detachably mounted on the grafting body 5 below the discharge hole 29. The dust shutter 30 may be a pipe.

With this configuration, foreign substances such as dust and dust in the clip storage container 28 storing a large number of grafted clips 9 can be easily discharged, and the discharged foreign substances pass through the dust shutter 30 to the outside of the machine. Can be exhausted.
Therefore, the grafting clip 9 can be moved smoothly, so that the cut grafting seedling can be gripped well, the joining rate can be further increased, and the working efficiency can be improved.

Further, since the automatic grafting device 4 is provided with the flow control valve 32 between the grafting pressure adjusting regulator 31 and the solenoid installation manifold, the flow rate is constant even in an optional air drive source. The actuator can be operated at a constant speed. Next, the operation will be described. First, the operator turns on the power switch 20 and the operation switch 22, and automatically selects the mode changeover switch 21.
And the hypocotyl of the rootstock 13 is set in the rootstock receiver 7.

Then, in response to a signal from a sensor (not shown) that senses this, the hand is moved inward in the horizontal direction by operating means using air as a drive source, and the hypocotyl of the scion seedling 11 is gripped. When the scion seedling supply device 12 is rotated by approximately 90 degrees and stopped at a position facing the scion seedling cutting device 15, the scion seedling cutting device 15 is rotated and synchronized with the timing. Returning to the position, at the time of this rotation, the cutting blade cuts a substantially predetermined position of the hypocotyl having cotyledons located on the near side. When the cutting of the hypocotyl is completed, the spikelet seedling supply device 12
Is further rotated by 90 degrees to face the joining place 8.

On the other hand, the rootstock 13 is carried out in the same manner as described above, and is conveyed to the position facing the joining place 8 by the rootstock supply device 14, during which the rotating rootstock cutting device rotates. A substantially predetermined position is cut by a cutting blade provided at 16. Subsequently, the air chuck of the scion seedling supply device 12 moves to the predetermined position in front, and the air chuck of the stock seedling supply device 14 also moves to the predetermined position in front, so that the cut surface of the scion seedling 11 and the stock are removed. The cut surface of the seedling 13 is pressed.

Since the clip supply device 10 which is in time with this pushes out the graft clip 9 whose grip portion is open, the grip portion of the pushed graft clip 9 is closed and then pressed. Tree seedling 11
The cut surface of the stock and the cut portion of the rootstock 13 are grasped to complete the production of the grafted seedling. When the joining operation is completed, the spikelet supply device 12
And the air chuck of the rootstock seedling supply device 14 alternates and returns to the original predetermined position, rotates toward the earling seedling receiver 6 and the rootstock seedling receiver 7, respectively, and stands by for the next operation. .

For manual operation, the mode changeover switch 21 is set from automatic to manual. Then, when the step switch 1 is pressed, the scion seedling supply device 12 advances toward the scion seedling receiving device 6 to perform a gripping operation of the seedling, and the stock seedling supplying device 14 moves toward the stock seedling receiving device 7. Move forward and perform the gripping operation of the rootstock seedling. Subsequently, when the step switch 1 is pressed, the spikelet seedling supply device 12 and the rootstock seedling supply device 14 rotate by about 90 degrees. Hereinafter, each time the step switch 1 is turned on, the following one operation is performed.

When the reset switch 2 is turned on, the operation is returned to the initial state. Therefore, it is effective when it is desired to return to the work start position during manual work. When the step switch 1 and the reset switch 2 are simultaneously turned on, the same operation as the automatic operation is performed according to the control program. Therefore, even if there is no grafting seedling, whether each operation is performed normally. You can easily find out. Thereby, maintenance efficiency can be improved.
