It is put into the split space 58.

The first protruding portion 66 is provided on the outer surface (outer surface plate 48) of the inner member 4, and the inner side surface (inner side surface plate 56) of the outer member 6 is provided so as to face the first protruding portion 66. It is preferable to provide the two protruding portions 68. With reference to FIGS. 2 to 4, the first projecting portion 66 is provided on the outer surface of the inner member 4 with a gap in the circumferential direction, and in this embodiment, each outer surface plate 48 (48a to 48h). The first projecting portions 66 are arranged in parallel with substantially equal gaps in the width direction of each outer surface plate 48 (48a to 48h) because the first projecting portions 66 are arranged substantially vertically in the vertical direction. It extends linearly in the vertical direction. Further, the second protruding portion 68 is provided on the inner side surface of the outer member 6 with a gap in the circumferential direction, and in this embodiment, each inner side surface plate 56 (56a to 56h) is inclined inward in the radial direction. The gap between the adjacent second projecting portions 68 is arranged so as to gradually decrease toward the lower side of each inner side surface plate 56 (56a to 56h), and has a diameter in the vertical direction. It extends linearly so as to incline inward in the direction.

The first and second projecting portions 66 and 68 are similarly configured, for example, as shown in FIGS. 3 and 4. That is, in this embodiment, the first protruding portion 66 (second protruding portion 68) includes an elongated first elastic member 76 (second elastic member 78), and the first elastic member 76 (second elastic member 78). Is attached via the first attachment member 72 (second attachment member 74). The first mounting member 72 (second mounting member 74) includes an elongated main body portion 80, a mounting side portion 82 provided on one side of the main body portion 80, and a support side portion 84 provided on the other side portion. The main body portion 80, the mounting side portion 82, and the support side portion 84 define a storage space 90 having an open upper surface.

The first elastic member 76 (second elastic member 78) is composed of an elongated elastic material having a circular cross section, and a part (bottom portion) thereof is a storage space 90 of the first attachment member 72 (second attachment member 74). Is housed in. In this embodiment, the mounting side portion 82 is provided with a plurality of (five in this example) female screw portions 92 with a gap in the longitudinal direction (vertical direction in FIG. 3 and the direction perpendicular to the paper surface in FIG. 4). By screwing the fixing screw 94 to these female screw portions 92 and allowing the tip portion thereof to act, the first elastic member 76 (second elastic member 78) becomes the first mounting member 72 (second mounting member 74). It is attached.

One of the first elastic members 76 (second elastic member 78) by bending the tip portion 96 of the support side portion 84 inward in order to more reliably hold the first elastic member 76 (second elastic member 78). It can be configured to wrap the portion from the outside. Further, in this configuration, the tip end side of the first elastic member 76 (second elastic member 78) protrudes from the first mounting member 72 (second mounting member 74), and the amount of protrusion on the mounting side portion 82 side increases. It can be configured to be larger than the protrusion amount on the other support side portion 84 side.

When the first elastic member 76 (second elastic member 78) is attached to such a first attachment member 72 (second attachment member 74), the inner member 4 has a relative movement direction. The first mounting member 72 is mounted on the outer surface of the inner member 4 so that the mounting side portion 82 is arranged on the downstream side (that is, the fixing screw 94 is located), and the outer member 6 is on the downstream side thereof. The second mounting member 74 is mounted on the inner surface of the outer member 6 so that the mounting side portion 82 is arranged (that is, the fixing screw 94 is located), and by mounting in this way, the bulb portion R is split into pieces. The rubbing force generated at this time can be sufficiently received by the support side portions 84 of the first and second mounting members 72 and 74. The main body 80 of the first mounting member 72 is attached to the outer surface (outer surface plate 48) of the inner member 4 by, for example, a mounting screw (not shown), and the second mounting member 74 is, for example. , The main body 80 is attached to the inner side surface (inner side surface plate 56) of the outer member 6 by a mounting screw or the like.

In this embodiment, the first mounting member 72 (second mounting member 74) is used to mount the first elastic member 76 (second elastic member 78), but the first mounting member 72 (second mounting member) 74) may be omitted. In this case, the first elastic member 76 (second elastic member 78) is attached to the outer surface (outer member 6) of the inner member 4 (outer member 6) by using, for example, an adhesive or a mounting bolt. Can be attached directly to the inner surface).

As such a first elastic member 76 (second elastic member 78), a member having an appropriate shape can be used, and the cross-sectional shape is, for example, an elliptical shape, a hexagonal shape, an octagonal shape, or the like, or the base side in the cross-sectional shape. It is also possible to use one having a square shape (that is, the mounting portion side) and a semicircular shape, a semi-elliptical shape, a triangular shape, or the like on the tip side (that is, the side acting on the scale diameter portion R).

Further, the first elastic member 76 (second elastic member 78) is preferably formed of an elastic material having an appropriate hardness, and can be formed of, for example, synthetic rubber, synthetic resin, or the like, and the synthetic resin is, for example. Silicon rubber can be used. With this configuration, when a large force acts when the bulb portion R is split, the first elastic member 76 (second elastic member 78) is appropriately elastically deformed, and thus the bulb portion R is elastically deformed. It is possible to prevent (scale P) from being damaged.

In this chopping machine, the gap of the chopping space 58 between the inner member 4 and the outer member 6 is adjustable. In this embodiment, as shown in FIG. 3, the inner side surface portion of the outer member 6, that is, the upper end portion and the lower end portion of the inner side surface plates 56 (56a to 56h) are radially outwardly bent lower bent portions. The 100 and the upper bent portion 102 are provided, and the lower bent portion 100 and the upper bent portion 102 are provided with elongated mounting holes 104 and 106 extending outward. On the lower end side of such an inner side surface plate 56 (56a to 56h), a mounting screw is attached to the lower connecting member 50 or the auxiliary connecting member 52 through the mounting hole 104 of the lower bent portion 100, and the upper end portion thereof. On the side, the mounting screw is attached to the upper connecting member 54 through the mounting hole 106 of the upper bent portion 102. Therefore, when mounting in this way, the inner side surface plates 56 (56a to 56h) are relative to each other in the radial direction from the position where the mounting screw is located at one end of the mounting holes 102 and 104 to the position where the mounting screw is located at the other end. The position can be adjusted in the direction of approaching and separating from the outer surface plates 48 (48a to 48h) of the inner member 4, in other words, the radial gap of the split space 58 can be adjusted. Can be adjusted.

In this embodiment, the inner side surface plate 56 of the outer member 6 is configured to be adjustable in position with respect to the outer side plate 48 of the inner member 4, but on the contrary, the inner side surface plate 56 of the outer member 6 is formed. On the other hand, the outer surface plate 48 of the inner member 4 may be configured to be adjustable in position, or both the outer surface plate 48 of the inner member 4 and the inner side surface plate 56 of the outer member 6 may be adjustable in position.

In this chopping machine, the bulb portion R of the bulb crop is chopped as follows. In order to perform this chopping mainly with reference to FIGS. 1 and 7, for example, the bulb portion R to be chopped may be put into the supply hopper 62 after the electric motor 34 is operated. When the electric motor 34 operates, the rotational power of the electric motor 34 is transmitted to the rotation shaft 30 as described above, and the inner member 4 is rotated in the direction indicated by the arrow 40.

In such a state, the size of the split space 58 between the inner member 4 and the outer member 6 changes with the rotation of the inner member 4 in the direction indicated by the arrow 40, and FIG. 5A shows. As shown in the above, in the portion where the gap (that is, the radial interval) of the split space 58 is large, the inserted bulb portion R is the first elastic member 76 of the inner member 4 and the outer member 6 of the outer member 6 due to its own weight. 2 It comes to be fitted between the elastic member 78. In this embodiment, since the outer surface of the inner member 4 and the inner surface of the outer member 6 have a regular octagonal shape, there are eight portions in the split space 58 in which the gap becomes large in the circumferential direction. In the explanation of, one of them is explained.

When the inner member 4 rotates in the direction indicated by the arrow 40 from the state shown in FIG. 5 (a), as shown in FIG. 5 (b), the gap of the portion where the scale diameter portion R is fitted in the split space 58. Is gradually reduced, and when the inner member 4 is further rotated in the direction indicated by the arrow 40, the gap at this portion is further reduced as shown in FIGS. 5 (c) and 5 (d). As can be seen from FIGS. 5A to 5D, as the inner member 4 rotates and the gap of the portion where the scale diameter portion R is fitted in the split space 58 gradually becomes smaller. In addition, the first elastic member 76 of the inner member 4 and the second elastic member 78 of the outer member 6 act on the bulb portion R, and the action acts to rub and tear. Therefore, the bulb portion R is split into small bulb portions R to scale P so as to be torn by the relative movement of the inner member 4 (first elastic member 76) and the outer member 6 (second elastic member 78). The scale portion R can be split into pieces.

After the chopping is performed in this way, the inner member 4 rotates in the direction of the arrow to return to the state shown in FIG. 5A, and the next bulb portion R to be chopped is the first of the inner member 4. It comes to be fitted between the elastic member 76 and the second elastic member 78 of the outer member 6, and the fitted bulb portion R is split as described above.

Further, as shown in FIG. 7, the scale portion R, which has been divided by the splitting and has become smaller, moves downward due to its own weight and has the first elastic member 76 of the inner member 4 and the second elastic of the outer member 6. The scale P, which has come to be fitted between the member 78 and further reduced by this splitting, does not fit between the first elastic member 76 of the inner member 4 and the second elastic member 78 of the outer member 6. , It falls to the scale receiving portion 60 through the lower opening of the split space 58 and is collected.

As shown in FIGS. 6 (a) and 6 (b), the portion where the scale-divided portion R, which has been divided into small pieces, is fitted in the divided space 58 by the rotation of the inner member 4 in the direction indicated by the arrow 40. The gap between the two is gradually reduced, and as a result, the first elastic member 76 of the inner member 4 and the second elastic member 78 of the outer member 6 are rubbed against the reduced bulb portion R as described above. It acts to tear, and the bulb portion R is divided into smaller bulb portions R to scale P, and the scale portion R reduced in this way can be similarly split. Such chopping with respect to the bulb portion R is performed on the lower side of the inner member 4 and the lower member 6 (that is, the lower side of the chopping space 58) as the size becomes smaller, and is thus chopped. The scales P are discharged downward from the split space 58.

In this embodiment, since the outer surface of the inner member 4 and the inner surface of the outer member 6 have a regular octagonal shape, the above-mentioned horo is made every time the inner member 4 rotates 1/8 (that is, rotates 45 degrees). Since the splitting is performed and the splitting is performed at eight parts in the circumferential direction of the splitting space 58, the work efficiency can be greatly improved. Further, the radial gap between the outer surface of the inner member 4 (first elastic member 76) and the inner surface of the outer member 6 (second elastic member 78), that is, the radial width of the split space 58 is directed downward. Since the bulbs are gradually reduced, the large bulbs R are split in the upper part of the split space 58, and the small bulbs R are split in the lower part of the split space 58, and the bulbs R of various sizes are split. Can be split into pieces.

Although one embodiment of the bulb-splitting machine of the bulbous crop according to the present invention has been described above, the present invention is not limited to such an embodiment, and various modifications or modifications can be made without departing from the scope of the present invention. It is possible.

For example, in the above-described embodiment, the outer member 6 is fixedly attached to the support main body 2 and the inner member 4 is rotated in a predetermined direction with respect to the outer member 6, but on the contrary, the inner member 4 may be fixedly attached to the support main body 2 so that the outer member 6 is rotated in a predetermined direction with respect to the inner member 4, or both the inner member 4 and the outer member 6 are relatively rotated. You may let it.

Further, for example, in the above-described embodiment, the outer surface (outer shape of the cross section) of the inner member 4 and the inner side surface (inner shape of the cross section) of the outer member 6 are formed in a regular octagonal shape. It may have a polygonal shape other than an octagonal shape, or a circular shape or an elliptical shape. In the case of a polygonal shape, it is preferably a square or more, and more preferably a regular polygonal shape such as a square cupola, a regular pentagonal shape, or a regular hexagonal shape.

Further, for example, in the above-described embodiment, the inner side surface of the outer member 6 is inclined inward in the radial direction (that is, toward the outer surface of the inner member 4) with respect to the outer surface of the inner member 4, which is related to this. Then, the gap between the adjacent second protruding portions (second elastic member 78) on the inner side surface portion (inner side surface plate 56) of the outer member 6 is gradually reduced downward, but the opposite is true. When the outer surface of the inner member 4 is inclined outward in the radial direction (that is, toward the inner surface of the outer member 6) with respect to the inner surface of the outer member 6, the outer surface portion of the inner member 4 (that is, also in this case) The gap between the adjacent first projecting portions (second elastic member 76) in the inner side surface plate 56) is configured to be gradually reduced downward.
