Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides grafting by supplying rootstock seedlings and scion seedlings as grafted seedlings, cutting them at predetermined positions, and joining the respective cut surfaces with a grafting tool. The present invention relates to a grafted seedling cutting device suitable for use in the device.

[0002]

2. Description of the Related Art In recent years, fruit vegetables cultivated in gardening facilities such as greenhouses have been grafted in order to avoid the harmful effects of continuous cropping and to increase the yield. A part of the work for making this graft uses auxiliary equipment, but most of it was done manually. When the graft is manufactured by hand like this,
Since a great deal of labor and time are required, various grafting devices have been proposed which can easily obtain grafts by supplying rootstock seedlings and scion seedlings.

[0003]

However, since the grafting seedling cutting device in the conventional grafting device cuts the rootstock seedling and the spikelet seedling by rotating the cutting blade, for example, the cutting blade in the rising process When the tree seedling is cut, as shown in FIG. 4, the cutting surface M of the rootstock seedling S becomes a curved surface. Considering the reason why the cut surface M of the rootstock seedling S becomes a curved surface in this way, the stalk to be cut is thick at the beginning of cutting, so the cut surface M is in a flat state, but the stalk to be cut at the end of cutting is Since the stalk becomes thinner and pushes the stem backward with the cutting blade, the stalk returns to its original state by its elasticity after cutting, even if the slicing face M during cutting is flat.
Because will rise.

Further, when the scion seedling is cut with the cutting blade in the descending process, the cutting surface M becomes flat at the beginning of cutting, so that the cutting surface M becomes flat at the cutting end, and the cutting stem becomes thin at the end of cutting. Since the stalk is pushed backward by the cutting blade, the stalk returns to its original state by its elasticity after cutting even if the cutting surface M during cutting is in a flat state.
Since the cutting surface M descends, as shown in FIG.
The cut surface M of is a curved surface. Therefore, since the cutting surface M of the rootstock seedling S and the scion seedling E becomes a curved surface, even if both seedlings S and E are joined using the grafting tool T as shown in FIG. Since the cut surface M of E does not contact each other and a gap is generated,
There was the inconvenience that the grafting error occurred and the yield was poor.

The present invention has been made to solve the above-mentioned inconvenience, and provides a grafted seedling cutting device capable of obtaining a cut surface free from grafting errors.

SUMMARY OF THE INVENTION The present invention is a grafted seedling cutting device for cutting grafted seedlings in a gripped state, the cutting having a V-shaped blade portion that is inclined at a predetermined angle with respect to the stem of the grafted seedling. The blade, the back-and-forth movement mechanism that moves this cutting blade back and forth, and the back of the stem of the grafted seedling abut when cutting the grafted seedling, and the sheath that fits in the advanced position of the cutting blade after cutting the grafted seedling. It is provided.

[0007]

In the grafted seedling cutting device according to the present invention, the V-shaped blade portion of the cutting blade positions the left and right positions of the grafted seedling,
The grafted seedlings are pressed against the pods, and the rootstock seedlings are cut without curving back and forth and left and right during the cutting process.

Illustration is omitted. Reference numeral 6 denotes a column, and a mounting plate 7 that is inclined at a predetermined angle so as to rise as it approaches the stem of the rootstock seedling S is attached to the upper end. The pillar 6 and the support pole 1 are attached to a base (not shown).

Reference numeral 8 denotes an air cylinder attached to the attachment plate 7, and a cutting blade attachment plate 9 parallel to the attachment plate 7 is attached to the tip portion of the rod 8a. The cutting blade mounting plate 9 is formed in a U shape in which the left and right ends are folded back upward to form a vertical piece 9a and open upward. The air cylinder 8 and the cutting blade mounting plate 9 described above constitute a forward / backward movement mechanism.

Reference numeral 10 denotes a cutting blade, which is attached to the tip of the cutting blade mounting plate 9 at a predetermined angle with respect to the stalk of the rootstock seedling S, and is mounted in parallel with the mounting plate 7 and the cutting blade mounting plate 9. It has a character-shaped blade portion 10a. Reference numeral 11 denotes an L-shaped support plate, which is attached to the attachment plate 2. Reference numeral 12 denotes a substantially U-shaped support plate, which is attached to the support plate 11 so that one end thereof is parallel to the cutting blade attachment plate 9.

Reference numeral 13 denotes a sheath, which is attached to the end of the support plate 12 facing the cutting blade 10 in parallel with the cutting blade mounting plate 9 so that the cutting blade mounting plate 9 and the cutting blade 10 can move in and out. The plate 14, the spacer 15, and the upper plate 16 are configured so that the left and right sides are open. And the lower plate 14
The end of the upper plate 16 on the cutting blade 10 side is located on the vertical line so as to be parallel to the stem of the rootstock seedling S. Reference numeral 17 denotes a guide plate, which is attached to the ends of the lower plate 14 and the upper plate 16 on the side of the cutting blade 10 so as to be positioned on the vertical line, and both ends are curved toward the support pole 1 which is an inner side.

Next, cutting of rootstock seedlings will be described. First, the pair of gripping members 5 is driven by a drive mechanism (not shown).
Is rotated to hold the rootstock seedling S. Next, the rotary cylinder 3 is rotated by a drive mechanism (not shown) to move the pair of gripping members 5 to the positions shown in FIG. 1, that is, the cutting blade 10 and the sheath 13.
Located between and. When the pair of gripping members 5 are rotated in this manner, the upper side of the stem of the rootstock seedling S gripped by the pair of gripping members 5 is guided by the guide plate 17, and is surely provided between the cutting blade 10 and the sheath 13. To position.

When the air cylinder 8 is operated to move the cutting blade mounting plate 9 back and forth, the cutting blade 10 advances to the position indicated by the chain double-dashed line in FIGS. 1 and 2 and then retracts. While positioning the left and right positions of the rootstock seedling S with the V-shaped blade portion 10a of 10, the rootstock seedling S is pressed against the lower plate 14, upper plate 16 and guide plate 17 of the sheath 13, that is, in the cutting process. The rootstock seedling S is sandwiched between the cutting blade 10 and the sheath 13 so that the rootstock seedling S is not curved in the left-right direction, and is cut while positioning.

Therefore, the cut surface M of the rootstock seedling S is shown in FIG.
As shown in FIG. Then, the cut upper part of the rootstock seedling S slides down on the cutting blade mounting plate 9,
For example, it falls into a storage box (not shown). When the cutting of the rootstock seedling S is completed in this way, the rotary cylinder 3 is rotated by the drive mechanism, and the process proceeds to the next step.

Although the description of cutting the scion seedling E is omitted, the forward / backward movement mechanism, the cutting blade 10, etc., and the sheath 13 are omitted.
When the lower part of the spiked seedlings E is dropped into the storage box while reversing the vertical relationship with the above, the cut surface M of the spikelet seedlings E is also in a flat state as shown in FIG. Becomes

As described above, according to the embodiment of the present invention, the V-shaped blade portion 10a of the cutting blade 10 and the sheath 13 are used to position the rootstock seedling S and the spikelet seedling E, and Since the cutting is performed while sandwiching it so as not to bend it to the left and right, the cutting surface M becomes a flat state. Therefore, when the two seedlings S and E are joined by using the grafting tool T, the two cutting surfaces M are in contact with each other without a gap, so that a grafting error does not occur and the yield is improved. Since the guide plate 17 is attached to the front end of the sheath 13, both seedlings S and E can be reliably guided to the cutting position.
Furthermore, since the unnecessary parts of both seedlings S and E that were cut were guided and dropped into a storage box, etc., the unnecessary parts of both seedlings S and E that were cut were not scattered around, and both seedlings S and E were stopped after the device was stopped. The tidying up work that collects the unnecessary parts that are cut off is unnecessary.

In the above embodiment, the cutting blade 10 is constructed by one piece, but if the cutting surface M can be a single plane, two blades can be combined. It may be V-shaped. Further, although an example in which the driving unit of the forward / backward moving mechanism is the air cylinder 8 has been described, other configurations may be used as long as the cutting blade 10 can be moved forward and backward. Furthermore, although an example in which the guide plate 17 is provided at the tip of the sheath 13 has been described, both ends of the sheath 13, that is, the lower plate 14 and the upper plate 16 may be formed in an arc shape, and the guide plate 17 may be omitted.

[0019]

As described above, according to the present invention, the grafted seedling is positioned by the V-shaped blade portion of the cutting blade and the sheath, and is cut while being sandwiched so as not to be bent in the front, rear, left and right. The cut surface of the grafted seedling becomes flat. Therefore, when the rootstock seedlings and the scion seedlings are joined using a grafting tool, both cutting surfaces are in contact with each other without a gap, so a grafting error does not occur,
Yield improves.
