Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting machine for bulbs and the like which is suitably used for obtaining small pieces such as bulbs in a method of growing a plant by tissue culture.

[0002]

BACKGROUND OF THE INVENTION Plant tissue culture techniques have been used for the production of virus-free plants and the mass propagation of selected plants. For example, as a method of mass-growing lilies, a growth method using tissue culture is used.The methods include splitting the flakes of small bulbs and transplanting them to a new medium to form bulbs, and inducing callus and growing them. There is a method of subdividing bulbs. In the former scale culture method, first,
Lily bulbs are sterilized by a standard method, cut into several millimeter squares with a sterilized scalpel, and the sections are cultured to form sterile small bulbs. Thereafter, scales are peeled off from the cultured small bulbs, cut, and then transplanted to a medium, and liquid culture or fixed culture is performed to form new bulbs.

[0003]

Heretofore, it has been customary to manually remove scales from cultured small balls of plants such as lilies and cut them into several millimeters by hand. However, since the cultured bulbs and their flakes are small, there is a problem that the work is troublesome, the work efficiency is low, and individual differences are likely to occur.

[0004] As an apparatus which can be used for mass-producing uniform culture sections while improving work efficiency, Japanese Patent No. 29519 is disclosed.
No. 73 describes a rotary plant cutting device using a motor as a driving source. However, since this apparatus can cut out only in one direction, even if it is suitable for obtaining a slice-shaped culture section, it cannot obtain a square-cut (lattice-shaped) cut piece. Therefore, when it is preferable to use a cut piece having a size of several millimeters, as in the case of tissue culture of lily, it is absolutely necessary to additionally perform a manual cutting operation. In addition, since the cut plant body slice cannot be directly put into the culture vessel, it is necessary to transfer the cut piece to a liquid medium or the like, which may cause contamination. Also,
The use of an electric motor complicates the device.

The present invention has been made in view of the above-described circumstances, and has a simple structure, for example, a method for cutting a square-cut piece for tissue culture from a piece of cultured bulb. It is an object of the present invention to provide an improved cutting machine such as a bulb which can be easily obtained without any individual difference, and which can directly put the cut pieces into a culture medium.

[0006]

According to the present invention, there is provided a cutting apparatus for cutting a bulb or the like, which comprises a cylindrical casing having a fixed blade at a bottom and an extruding rod having an extruding plate at a tip. The fixed blade is composed of an upper fixed blade group and a lower fixed blade group that are stacked in two stages with the directions of the blades orthogonal to each other, and the extruded plate is formed with a notch that can enter the fixed blade. It is characterized by.

[0007] The cutting machine for bulbs and the like according to the present invention, when used, includes a bulb, cultured small bulbs,
Alternatively, an object to be cut such as scale is put in, and an extruding rod is inserted from above to push down in the direction of the fixed blade. At that time,
Preferably, the cylindrical casing is placed in a vertical position with respect to the culture medium. By pushing down the push rod, the pushing plate pushes the cut object toward the upper fixed blade group, and by further pressing down, the cut object is gradually fed into the upper fixed blade group, and the blade body in the first direction. Get cut.

The extruded plate is formed with a notch that can enter the fixed blade, and when the extruding rod is pushed down, the distal end surface of the extruded plate enters the upper fixed blade group. Thus, the cut pieces cut out by the upper fixed blade group are gradually fed into the lower fixed blade group. The direction of the blades of the lower fixed blade group is orthogonal to the direction of the blades of the upper fixed blade group, and the cut pieces cut out by the upper fixed blade group have a second direction orthogonal to the first direction in the lower fixed blade group. In the direction of. As a result, the cut object is finally cut into cut pieces having a horizontal cross section (lattice shape) and falls from the cylindrical casing. By placing the container containing the medium below, the cut pieces in a square shape are placed on the medium as it is.

As described above, in the cutting machine such as a bulb of the present invention, a cut object such as a bulb is finally cut into a square shape, that is, a lattice shape. When trying to cut a cut object such as a bulb into a grid by one cut, it is necessary to arrange the fixed blades in a cross shape on the same plane,
The load is concentrated on the cross section, which becomes a cross, and the tissue is likely to collapse. Such collapse is a fatal disadvantage for tissue culture. In the present invention, cutting in two stages, that is, first cut in one direction by the upper fixed blade group, and then cut in the orthogonal direction by the lower fixed blade group, so that the tissue collapse Without
Cut pieces cut into squares (lattices) can be obtained.

[0010] In addition, the area of the blade that hits the cut object at one time at the time of each of the upper and lower tiers is reduced as compared with the case where the fixed blades are arranged and cut in the same plane in a cross shape. Therefore, even if the push rod is pushed down under the same conditions, the pressing force of the object to be cut against the blade is doubled as a result, and the cutting is performed smoothly and a smooth cut surface is obtained.

Preferably, the cuts formed in the extruded plate are a number of cuts perpendicular to each other at intervals corresponding to the intervals between the respective blades of the upper fixed blade group and the lower fixed blade group, and the depth of the cut is The depth is such that both the fixed blade group and the lower fixed blade group can enter. With such a configuration, the cutting of the cut object by the lower fixed blade group proceeds smoothly, and the cut pieces after the cutting are reliably discharged from the cylindrical casing. In addition, fixed blade,
It may be a wire like a piano wire, but preferably,
It is composed of a plurality of thin blade plates parallel to each other. As a result, it is possible to obtain a cut piece having a more uniform size and a flat cut surface.

The cutting machine according to the present invention is a particularly suitable cutting machine when the object to be cut is a bulb, a cultured small bulb, or a flake thereof. However, the present invention is not limited to this, and can be applied to all plants that become clumps due to growth, and also to those that are shipped with multiple shoots. Can be. For example, as specific plants, fig family plants such as benjamin, and taro plants such as symgonium, philodendron, and spasifiram can be used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a cutting machine for bulbs and the like according to the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view showing a tubular casing 10 constituting the cutting machine 1, and FIG.
FIG. 2 is a perspective view showing an extruding rod 30 inserted into the inside. FIG. 3 is a perspective view showing a state where the push rod 30 is inserted into the cylindrical casing 10, and shows a state before cutting the cut object.

The cylindrical casing 10 has a through body 15 having a through passage 15 formed by integrally fixing a front plate 11 and a rear plate 12 by left and right side walls 13 and 14.
And a fixed blade device 20 fixed to the bottom of the cylindrical body 16. The fixed blade device 20 includes an upper frame 21 and a lower frame 2.
6, and through holes 22 and 27 having substantially the same cross-sectional shape as the through passage 15 of the cylindrical body 16 are formed in each frame.

The two opposing sides of the upper frame 21 are
A large number of slits 23 are formed at predetermined intervals (intervals of about several millimeters). In each slit 23, a thin blade plate 24 having a sharp blade on the upper edge side is inserted and detached by appropriate means. It can be mounted in any manner. Thereby, an upper fixed blade group is formed. A slit 28 is also formed in the lower frame 26 in the same manner as the upper frame 21, and a thin blade plate 29 having a sharp blade on the upper edge side is also inserted,
It is attached in a detachable manner by appropriate means. Thereby, a lower fixed blade group is formed. Therefore, both the upper fixed blade group and the lower fixed blade group can be exchanged, and the mounting interval of the thin blade plate can be changed.

As shown in the figure, the upper casing 21 and the lower casing 26 are turned by 90 degrees so that the cylindrical casing 1 is turned.
0, so that the fixed blade device 2
Reference numeral 0 denotes a shape in which a thin blade plate 24 as an upper fixed blade group and a thin blade plate 29 as a lower fixed blade group are arranged in two stages vertically and in an orthogonal posture.

The push bar 30 has a push plate 31 on the tip side and a handle 35 attached to the back surface of the push plate 31. The horizontal cross-sectional shape of the extrusion plate 31 is substantially the same as the cross-sectional shape of the through-passage 15 in the cylindrical body 16 of the cylindrical casing 10, and the thickness is, in this example,
The upper frame body 21 and the lower frame body 26 have a thickness such that they overlap each other.

On the front side of the push plate 31, when the push rod 30 is inserted into the cylindrical casing 10, a thin blade plate 24 as an upper fixed blade group and a thin blade plate 29 as a lower fixed blade group are provided. The cuts 32 perpendicular to each other, into which the blade plate can enter,
33 are formed. That is, one cut 32
Is a cut in the same direction and in the same direction as the thin plate blade plate 24 as the upper fixed blade group, and the other cut 33 is a cut in the same direction and in the same direction as the thin plate blade plate 29 as the lower fixed blade group. is there. The depths of the cuts 32 and 33 are both set so that at least both the upper and lower thin blade plates 24 and 29 can enter when the push rod 30 is pushed down.

With the above configuration, in using the same,
The tubular casing 10 is placed in an upright posture above an appropriate medium, and a cut object such as a bulb, a cultured small bulb, or scale is placed in the tubular casing 10. In this position, the push rod 30 is inserted from above and pushed down. By pressing down, the lower surface of the extrusion plate 31 abuts on the cut object,
By further pressing down, the cut object is gradually fed into the thin blade plate 24 as the upper fixed blade group. By the feeding, the cut object is cut in the first direction by the thickness of the blade-shaped blade plate 24 at the blade interval, and cut into thin pieces.

When the push rod 30 is further pushed down, the push plate 31 moves the thin plate-shaped blade plate 24 as an upper fixed blade group into one of the cuts 32,
It reaches the lower end surface of the upper frame 21. In the process, the cut pieces cut into flakes with the thickness of the blade interval of the thin blade plate 24 are gradually fed into the thin blade plate 29 as the lower fixed blade group, and the blades of the thin blade plate 29 are cut. At the thickness of the gap, the sheet is cut in a second direction, that is, in a direction perpendicular to the first direction, whereby the horizontal section is cut into square-shaped (lattice-shaped) cut pieces having a few millimeters square. .

When the push rod 30 is further pushed down, the push plate 31 is moved downward while the thin plate-shaped blade plate 29 as the lower fixed blade group is inserted into the other cut 33 provided at right angles to the one cut 32. It moves to near the lower end surface of the frame 26. As a result, the cut pieces in a square shape are pushed out from the lower end of the tubular casing 10 by the pushing plate 31, and fall into the culture medium located below.

As described above, in the cutting machine 1 such as a bulb of the present invention, one-way cutting is first performed by the thin blade plate 24 as the upper fixed blade group, and then the lower fixed blade group. Since the cutting in the orthogonal direction is performed by the thin blade plate 29, there is an advantage that a cut piece cut into a square cut (lattice shape) can be easily obtained without crushing the tissue. There is.

In the experiments of the present inventors, when the scales are manually removed and cut, the number of slices that can be placed on the culture medium is usually about 100 to 150 per hour. By using the above cutting machine by
About 500 to 3000 pieces could be processed.

In the illustrated example, the extruded plate 3
1. Cuts 32, 33 in two directions perpendicular to each other are formed on the front side of the base 1, and the depths of the cuts 32, 33 are such that both the upper and lower frame members 21, 26 can be inserted, at least the upper and lower thin plates. The depth is such that both of the blade plates 24 and 29 can enter. This is to ensure that the cut pieces cut into a square shape are pushed out from the lower end of the cylindrical casing 10 and fall down, and the cut pieces cut into the square shape are attached to the lower frame 26. If it falls naturally between the thin blade plates 29, or if it can be dropped by shaking the entire cutting machine, the cut formed on the front side of the extrusion plate 31 is only one cut 32, That is, it is understood that only the cuts in the same interval and in the same direction as the thin blade plate 24 as the upper fixed blade group need be made. At this time, the depth of the cut 32 is set to such a depth that the front surface (lower end surface) of the pushing plate 31 can be moved to just before the cutting edge of the thin blade plate 29 which is the lower fixed blade group.

[0025]

As described above, according to the cutting machine for bulbs and the like of the present invention, plants that become clamped (lumps) by growth, such as bulbs, cultured small bulbs, or their flakes, are cut into squares ( When cutting into a (lattice shape), it was cut in two stages, that is, first, cutting in one direction was performed by the upper fixed blade group, and then cutting in the orthogonal direction was performed by the lower fixed blade group. Thus, it is possible to quickly obtain a cut piece cut into a square shape without crushing the tissue.

In addition, as compared with the case where the fixed blades are arranged in a cross shape in the same plane and cut, the area of the blade that hits the cut object at one time in each of the upper and lower stages is reduced by half. In addition, as a result, the pressing force of the object to be cut against the blade is doubled, the cutting is performed smoothly, and a smooth cut surface is obtained.
