A sliding rod 28 is fixed to the end of the cutting blade sliding cylinder 27 and slides in the hole, and a sliding rod 28 is connected to the second crankshaft 13 and comes into contact with the sliding rod 28 to slide it. It is connected to a cutting blade drive rod 29 that moves the cutting blade.
The cutting blade 26 has a shape in which the angle is cut diagonally toward the ridgeline and a blade is attached to the cut end.

FIG. 11 is a plan view of the drilling mechanism 7, and FIGS. 12 and 13 are front views showing the state of the drilling mechanism 7 during drilling and insertion of cuttings. FIG. 14 is an explanatory diagram showing the state of drilling the rootstock seedling 3 and inserting the cutting seedling 1.

The drilling mechanism 7 includes a drilling rod 30 having a cutting edge for drilling a hole in the stem of the rootstock seedling 3;
A hole is drilled while attached to the hole, and an insertion auxiliary rod 31 is used to guide the cutting seedling 1 after the hole is drilled, and a first support rod 32 is used to support both at a fulcrum, and a time difference is provided between the operations of both. It is connected to a time difference plate 33.

The time difference plate 33 is a plate having a curved surface with respect to the longitudinal direction of the insertion auxiliary rod 31, contacts the insertion auxiliary rod 31, is pivotally supported by the crank portion of the first crankshaft 12, and is Along with the rotation, the insertion assisting rod 31 is rotated up and down.

The elevating mechanism 8 includes an elevating arm rod 34 that is pivotally supported by the first crankshaft 12 and performs a seesaw movement by pushing down the first fixed plate 23, a second support column 35 that supports this arm rod with a support shaft, and a second fixed plate 25. A guide rod 36 is installed upright on the opposite side of the clamping claw 9, a compressed second coil spring 37 is fitted around the guide rod 36, and a first fixed plate is installed upright to fit around and guide the guide rod. It is connected to the guide tube 38.

Therefore, the cutting and seedling clamping mechanism 2 and the rootstock and seedling clamping mechanism 4 are connected via the guide rod 36 and the guide cylinder 38, and when the lifting arm rod 34 pushes down the first fixing plate 23, the cutting and seedling clamping mechanism The mechanism 2 can be lowered to the correct position of the rootstock seedling clamping mechanism 4, and the second coil spring 37 raises the first fixing plate via the guide tube 38 in response to the rise of the lifting arm 34. become. Note that the guide rod 36 and the guide tube 37 are inclined at an angle suitable for the drilling direction.

The rotation mechanism 5 includes a key-shaped driving arm rod 39 connected to the second crankshaft 13 and capable of reciprocating up and down movement, a rotating plate 41 having a serrated convex portion 40 that engages with the key shape, and a rotating plate 41. The rotary cylinder 42 is fixed to the support arm 24 of the first fixing plate 23 and the second fixing plate 25. Since the driving arm rod 39 engages with the convex part 40 during the backward movement and draws the convex part 40, the rotary plate 41 moves one pitch per rotation of the second crankshaft 13, that is, the cutting and seedling holding mechanism 2 and the rootstock. It rotates by the width of one set of clamping mechanisms 4.

The clamping claw opening/closing mechanism 10 has a first fixing plate 23 and a second fixing plate 23.
an opening/closing lever 22 with one end protruding from the fixed plate 25 and the other end locking the first coil spring 19 and rotating;
A lever locking rod 43 that comes into contact with the opening/closing lever 22 to stop the rotation of the opening/closing lever 22 or separates from the opening/closing lever 22 and rotates downward, and a torsion that restricts the rotation of the lever locking rod 43. The third coil spring 44 has a shape similar to that shown in FIG.

When the gripping claw 9 is opened, the third coil spring 44 is relaxed, and the lever locking rod 42 is connected to the opening/closing lever 22.
Although they are located below or above and are not engaged, the lever locking rod 42 can be rotated by rotating the opening/closing lever 22.
When brought into contact with the clamping claw 9, the clamping claw 9 becomes open, and is maintained in the open state by the urging of the third coil spring 44, and the lever locking rod 43 is projected by lowering the cutting seedling clamping mechanism 2. When the piece 45 is abutted and rotated, the locked state between the opening/closing lever 22 and the lever locking rod 43 is released, and the gripping claw 9 opens.

[Effect] Appropriate cuttings 1 and rootstocks 3 are selected.
When the stem of the cutting seedling 1 is placed on the open clamping claw 9 of the cutting seedling clamping mechanism 2 and the opening/closing lever 22 is pulled toward you, the sliding hole 20 of the support shaft 21 slides and engages with the support shaft 21. Both ends of the X-shaped opening/closing rod 18 are closed via the first coil spring 19, and the clamping claws 9 are closed to clamp the stem of the cutting seedling 1. Here, the lever locking rod 43 is rotated by the third coil spring 44 to a position where it comes into contact with the opening/closing lever 22 and stops the opening/closing lever 22, so that the clamping claws 9 maintain clamping of the cutting seedling 1.

The rootstock seedling 3 is similarly held by the holding claws 9 of the rootstock seedling holding mechanism 4.

When the first gear 15 is rotated once while holding the handle 14, the drive arm rod 38 pulls the protrusion 40 of the rotating plate 41 one pitch through the chain 7, the second gear 16, and the second crankshaft 13, and the rotating plate The rotary cylinder 42 rotates one pitch together with the rotation cylinder 41. Therefore, the support arm 24
The cutting and seedling clamping mechanism 2 and the rootstock and seedling clamping mechanism 4 are moved one pitch through.

Rotation is continued while the cutting seedling 1 and the rootstock seedling 3 are successively held between the holding claws 9. When the cutting seedling 1 has rotated to the position of the cutting mechanism 5, the cutting blade drive rod 29 that was holding down the sliding rod 28 is released, and the coil spring inside the cutting blade sliding tube 27 is energized to move the cutting blade 26 forward. let
The cutting blade 26 cuts the stem of the cutting seedling 1 into a wedge shape. Then, as the second crankshaft 13 rotates, the cutting blade drive rod 29 pushes the sliding rod 28 and stores the cutting blade 26 into the cutting blade sliding cylinder 27. In this way, the stems of the cuttings 1 are sequentially cut and the cuttings are moved.

When the rootstock seedling holding mechanism 4 holding the rootstock seedling 3 moves to the position of the drilling mechanism 7, the insertion auxiliary rod 3
1 is attached to the first crankshaft 1.
As the rootstock 2 rotates, it descends to the position of the rootstock seedling 3 and sticks diagonally into the stem between the twin leaves of the rootstock seedling 3 to make a hole.

The reason why the hole is made diagonally is that there is a vertical hole in the center of the stem, and if the cutting seedling 1 is inserted into this hole, it will not take root properly. This is because if the cutting seedling 1 is inserted, it will take root well.

When the drilling is completed, the drilling rod 30 rises as the first crankshaft 12 rotates. However, due to the action of the time difference plate 33, the insertion assisting rod 31 remains stuck in the stem.

Next, the tip of the lifting arm 34 rotates and descends, and the first
The fixing plate 20 is pushed down obliquely, and the cutting seedling 1 reaches the hole in the stem of the rootstock seedling 3. At this time, since the gutter-shaped insertion assisting rod 31 remains stuck in the stem, the wedge-shaped cut portion of the cutting 1 is easily inserted diagonally into the hole along the gutter shape. Then, the insertion assisting rod 31 is raised by the action of the time difference plate 33.

At this time, the first fixing plate 23 is at the closest position to the second fixing plate 25, and each lever locking rod 43 comes into contact with each protruding piece 45.
The lever locking rod 43 rotates and comes off from the opening/closing lever 22. The opening/closing lever 22 is released, the first coil spring 19 is restored, and the gripping claws 9 are opened, so that the rootstock seedling 3 with the cutting seedling 1 inserted therein separates from the gripping claws 9 and falls.

Next, as the elevating arm lever 34 rises, the second coil spring 37 fitted around the guide rod 38 tries to restore its original state, pushing the first fixing plate 23 up diagonally to its original position.

The above operations are performed one after another.

[Effects of the Invention] The device of the present invention has the effect of being able to easily and efficiently graft seedlings of vegetables, etc., continuously and in a short time without requiring any skill.
