1 is a perspective view showing an example of a graft cutting device. The base cutting device is a stem supporting means (1) consisting of a pair of members (supporting means 1a, 1b) supporting the stem for grafting by means of relative movement in close and half directions and moving in a close direction. And a stem cutting means (2) having a transversal blade (2a) for cutting the supported stem transversely and an end blade (2b) for inserting a perforation line in the stem length, and the stem supporting means (1) in the proximal direction of the stem supporting means (1). It consists of a cutting blade actuating means (3) for operating the transversal blade (2a) and the end blade (2b) in response to movement.

The stem support means 1 consists of a 1st support means 1a and a 2nd support means 1b. The first supporting means 1a is formed by connecting a pair of face plates 4 facing each other through a connecting portion 5 to form a door shape that opens laterally. A concave surface portion 6a is formed at the front end of the face plate 4. Is formed. In addition, a through hole 7 (see FIG. 4A) is formed at the center of the connecting portion 5. On the other hand, the second supporting means 1b is formed in a plate shape, and one side surface portion is formed with a concave surface portion 6b as shown in Fig. 3, and at the same time, a horizontal escape groove 8a and a vertical escape groove 8b. ) Is formed into a T shape. The first supporting means 1a and the second supporting means 1b are disposed to face each other, and are configured to be able to support the side surfaces of the trunks of the base trees in the concave surface portions 6a and 6b by being close to each other. do. In addition, these concave surfaces may be U-shaped or V-shaped.

Next, the stem cutting means 2 has a horizontal slit 10a and a longitudinal cross section (large diameter portion) of the columnar body 9 in which the large diameter portion 9a and the small diameter portion 9b are continuously formed as shown in FIG. The slits 10b are formed in a T-shape, the transverse blades 2a and the end blades 2b are inserted into the slits 10a and 10b, and the large diameter portion 9a is tightened with the support ring 11. I supported it. The stem cutting means 2 is disposed between the face plates 4 and 4 of the first supporting means 1a, and the small diameter portion 9b penetrates the connecting portion 5 of the first supporting means 1a. It penetrates the ball 7 and protrudes outward.

The cutting blade actuating means 3 is intersected in an X shape, one part 3a is gripped, and the stem supporting member 1 is disposed at the other end. In addition, the first supporting means 1a is not directly supported at the other end portion, but instead of the columnar body 9 constituting the stem cutting means 2 as shown in Figs. 2 and 4 (a). It is supported by the edge part of the small diameter part 9b. The stem cutting means 2 is always urged by the spring 12 mounted on the small diameter portion 9b so that the transversal edge 2a and the end edge 2b enter the space S between the face plates. . For the sake of safety, the transversal edge 2a and the terminating edge 2b are preferably configured to enter the space S. In addition, the cutting blade operating means 3 is set so that both ends are always opened by the spring 13. When the grip 3a is firmly held against the spring 13, the stem support member 1 is moved relative to each other in the proximate direction, but when it is retracted, the columnar body 9 is pushed in to retract the stem cutting means 2.

Therefore, when the grip 3a is gripped again, the stem supporting member 1 cannot already move in close proximity, and accordingly, the stem cutting means 2 is secondly opposed to the spring 12 as shown in FIG. It protrudes toward the support means 1b side. The stem a supported by this is cut | disconnected horizontally by the transversal edge 2a, and a perforation line enters longitudinally by the terminal edge 2b. In addition, the transversal blade 2a and the terminal blade 2b cut into the stem a and pass into the escape grooves 8a and 8b of the second supporting means 1b. Thereafter, when the force applied to the grip 3a is released, the stem supporting member 1 is moved in the half direction by the spring 13 to open. As a result, the stem a becomes the base 14 for the weaving contact having a flat cut surface a1 and a cutout line a2 as shown in FIG. 5.

Next, another embodiment of the base wood cutting device will be described with reference to FIGS. 6 to 10.

Fig. 6 is a perspective view showing a grafting underwood cutting device, and Fig. 7 is a plan view of main parts of the cutting device. The cutting device is composed of a device body 20 and a slide member 21 provided to be slidably accessible to and separated from the device body 20.

The guide body 22 protrudes horizontally toward the slide member 21 in the apparatus main body 20, and at the same time, the grip piece 23a is formed in the upper part. On the other hand, a lower portion of the slide member 21 is provided with a fitting portion (not shown) for fitting the guide rail 22 so as to be free to slide and at the same time both sides of the guide rail 22 from the fitting portion. A pair of guide parts 24 for guiding are projected horizontally. Moreover, the holding piece 23b is formed in the upper part of the slide member 21. In addition, a tension spring 25 is attached to the tip of the guide rail 22 and the slide member 21. Accordingly, the guide rail 22 slides between the fitting portion and the guide portion 24 so that the slide member 21 can slide with respect to the apparatus main body 20, and the slide member 21 can be moved. When the slide is approached (20) and the force is released, the slide member 21 automatically slides back from the device body 20 to the original position by the spring force of the tension spring 25.

In addition, a transverse blade 2a is supported between the fixing plate 26 and the guide rail 22 of the apparatus main body 20 to protrude laterally, and the blade is attached to the slide member 21 side. . Moreover, the vertical support part 29 protrudes from the said holding piece 23a toward the slide member 21 side, and the support part 29 is supported by the terminal edge 2b. The end blade 2b protrudes below the support part 29, and the blade is attached so as to face the slide member 21 side. The end edge 2b is arranged in the slide direction with the transversal edge 2a and is provided to protrude downward from the position of the transverse edge 2a, and the transverse edge 2a is the slide member 21 rather than the end edge 2b. It is arranged near by.

In addition, the apparatus main body 20 is provided so that the auxiliary slider 30 can slide in the same direction as the slide member 21 at the lower portion of the position where the transversal blade 2a and the terminal blade 2b are provided. At the front end surface of the auxiliary slider 30 is formed a receiving portion 31 of the stem (a) for the bottom and at the same time the escape groove 32 to avoid the coupling with the end edge (2b) in the longitudinal direction Is formed. In addition, the jaw portion 33 is formed outside the receiving portion 31. And the auxiliary slider 30 is from the position where the receiving part 31 protrudes toward the slide member 21 rather than the transversal edge 2a to the position where the jaw part 33 is coupled to the wall 34 of the apparatus main body 20. You can slide between. In addition, the tension slider 35 is attached to the auxiliary slider 30 and the apparatus main body 20, and thus the auxiliary slider 30 is always urged toward the slide member 21 side.

Next, the slide member 21 is provided with a convex portion 36 protruding toward the device body 20 on the side opposite to the auxiliary slide 30 of the device body 20, the front end of the stem ( The receiving part 39 which receives the side surface on the opposite side to a) is formed. Both the receiving part 39 and the receiving part 31 of the slider 30 receive the side surface of the trunk stem a, and are preferably formed in a V shape or a U shape.

The slide member 21 is the front end of the receiving portion 39 is coupled to the receiving portion 31 of the auxiliary slider 30, in this state the jaw portion 33 of the auxiliary slider 30 is the device body 20 It is slidable until it reaches the wall 34, which is the moving range of the slide member (21). However, in the case of sliding in this way, the receiving portion of the slide member 21 is coupled to the transversal blade 2a and the terminal blade 2b in the middle of the movement range. Thus, the slide member 21 is formed in the receiving portion 39 and the escape portion to avoid the coupling between the transversal blade 2a and the terminal blade 2b of the apparatus main body 20 during the slide. That is, the receiving part 39 is formed with a horizontal evacuation groove 8a for avoiding the transversal edge 2a and a vertical evacuation groove 8b (see FIG. 7) for avoiding the end edge 2b. In addition, the upper part 39a of the receiving part 39 is inclined.

Next, the use mode of the cutting device of the said structure is demonstrated by FIGS. In the figure, the support part 29 of the terminal edge 2b is abbreviate | omitted. First, as shown in FIG. 8, the stem (a) side of the plant used for the grafted underwood is coupled to the receiving portion 39 of the slide member 21, and then the slide member 21 and the device body 20 with fingers. The holding pieces 23a and 23b of the hand are held by the fingers of one hand and slide so that the slide member 21 and the apparatus main body 20 approach each other. In practice, since the stem (a) is cut so as not to move, it is good to slide the apparatus main body 20 to approach the slide member 21. Accordingly, the receiving part 31 of the auxiliary slide 30 is coupled to the side of the side where the stem a is empty, and the stem a is the receiving part 39 of the slide member 21 and the auxiliary slider 30. It is supported between 31 and the posture is stabilized. When it slides again in this state, as shown in FIG. 9, the transversal blade 2a cut | disconnects the stem a horizontally, and is cut horizontally. At this time, the transversal edge 2a passes through the horizontal escape groove 8a of the receiving part and does not engage the receiving part 39. In addition, when the slide is moved, the vertical edge 2b passes through the stem a, so that a vertical cutting line enters the stem a as shown in FIG. At this time, the end blade (2b) passes through the vertical escape groove (8b) of the receiving portion and does not engage the receiving portion (39).

After reaching the slide moving end, the force applied to the gripping pieces 23a and 23b is released, and the spring springs of the tension spring 25 of the slide member 21 and the tension spring 35 of the auxiliary slider 30 are released. The apparatus body 20 and the slide member 21 are separated, and the slide member 21 and the auxiliary slider 30 are moved back to their original positions. From the receiving part 39 of the slide member 21, as shown in FIG. 5, the base 14 containing the horizontal cut surface a1 and the vertical cut line b1 can be taken out.

As described above, by sliding the slide member 21 by one stroke, the flat cut of the stem a and the perforation line can be carried out, whereby the base wood for weaving can be easily produced.

In addition, since the slide member 21 and the auxiliary slider 30 are automatically returned to their original positions by the spring force of the tension springs 25 and 35 after cutting the stem a, the continuous cutting operation can be efficiently performed.

In addition, the auxiliary slider 30 is not necessarily necessary, but since the stem for a base (a) can be stably supported by the slide member 21 and the auxiliary slider 30, the stem is always accurately ) Can be cut.

In addition, the method of arranging the end edge 2b to be slightly inclined with respect to the stem a is easier to cut the stem a more easily.

When the cutting of the trunk stem a is mechanized and automated, the slider 30 may be supported and the apparatus main body 20 may be slidably moved by appropriate means.

According to the invention according to claim 1, in response to the stem supporting member being close to supporting the stem for the tree, the cutting blade actuating means cuts the stem supported by the cross cutting blade transversely by a transversal blade, Since the perforations are vertically cut by the blade, you can easily make a weaving tree.

Therefore, by operating the stem support member in close proximity and half, a flat cut of the stem and a perforation line can be performed, thereby making it possible to simply produce a weaving base wood. Because of this, workability is good and the structure is simple, so it is suitable for mechanization and automation.

According to the invention according to claim 2, when the stem is coupled to the base portion of the slide member slides, since the stem is cut horizontally across the transversal edge and passes through the end edge, the longitudinal cut line enters the remaining stem. At this time, since the transverse edge and the end edge of the transverse edge are formed in the receiving portion and the vicinity of the slide member, the slide member can be moved smoothly.

Therefore, even in this case, by moving the slide member by one stroke, a flat cut of the stem and a perforation line can be performed, thereby making it easier to produce a grafting base wood. Because of this, workability is good and the structure is simple, so it is suitable for mechanization and automation.

According to the invention according to claim 3, since the stem for the base can be stably supported at the receiving parts on both sides of the slide member and the auxiliary slider, the stem can be cut accurately all the time. After cutting, the auxiliary slider does not need to be returned to the original position because the auxiliary slider moves back to the original position by the spring bias.
