Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a beard cutting thread used in a device for cutting beard roots of radish after harvesting.

[0002]

[Prior Art]

 As is well known, the beard cutting thread in the conventional beard cutting device for radish is, as shown in FIG. 13, provided on the outer peripheral portions of a pair of circular side plates 13 supported by the drive shaft 14 of the reel-shaped rotating body 12. Threads 18 are provided by appropriately slacking the holes 17 at positions corresponding to each other of the holes 17 arranged at equal intervals in the circumferential direction. When the rotating body 12 is rotated at a high speed in this state, a centrifugal force acts on the yarn 18 to form a quadratic curve in which the middle portion bulges outward from the knot positions at both ends as a starting point, and the tension increases. When the yarn 18 protruding in the shape of a quadratic curve and rotating at high speed comes into contact with the beard root portion of the radish, the beard root is cut by its speed and tension.

In such a conventional beard root cutting thread, the thread often breaks during the operation of cutting the beard root due to the condition of the beard root, the fatigue of the thread itself, or the like. It is necessary to interrupt and replace the thread. To replace the thread, it was necessary to remove the knot at each end of the broken thread, remove it, and then tie a new thread to each hole.

However, since this thread is usually made of a thin single wire made of a resin such as nylon, it has elasticity and it is necessary to remember a unique tying method to tie the knot so that it will not come off. Of course, it took time to replace the thread. Also, if the length of the newly tied yarn is too long compared to the length of other yarns, the radish may be damaged when cutting the beard root, while if it is too short, the beard root may be removed completely. Can not be removed. Therefore, when replacing a yarn, it is necessary to make sure that the new yarn has the same length as the other yarns, which is a very difficult and time-consuming task.

At this time, the length of the thread body is preset, and it is not necessary to adjust the length between the new thread assembly and another thread assembly. In addition, the sleeve protects the thread body from coming into direct contact with the support metal and is easily cut, and the metal ring that secures the sleeve to the thread body ensures engagement between the thread assembly and the support metal fitting. If the thread body is cut during use, it is replaced by removing the cut thread assembly from the support and installing a new thread assembly as described above.

Further, by fixing the support fittings to the appropriate two holes of the cylindrical rotating body and attaching the thread assembly to the support fittings as described above, the length of the thread main body corresponding to the size of the radish can be increased. Adjust to

[0010]

【Example】

 The beard cutting thread in the beard cutting device for radish according to the embodiment of the present invention is, as shown in FIG. 1, a yarn assembly 1 and a yarn assembly on a rotating body 10 rotated by a beard cutting device (not shown). It is composed of a support fitting 6 for detachably attaching the solid body 1. The rotating body 10 in this embodiment is formed in a cylindrical shape, and a plurality of screw holes 11 are provided on the peripheral surface thereof at appropriate intervals in the circumferential direction and the axial direction.

As shown in more detail in FIGS. 2 and 3, the thread assembly 1 includes a thread body 2 having a predetermined length, sleeves 3 attached to both ends of the thread body 2, and a sleeve 3 inserted on the sleeve 3. The metal ring 4 is attached to fix the sleeve 3 to the thread body 2 by caulking 5. The mounting position of the metal ring 4 is such that the sleeve 3 prevents the thread body 2 from directly contacting the support metal 6 when engaged with the support metal 6, which will be described later, and the metal ring 4 engages with the support metal 6. In addition, it is preferable that they are located at both ends of the thread body 2.

As shown in more detail in FIGS. 4 and 5, the support fitting 6 has a slit 7 on the side surface through which the thread body 2 can pass, and allows the sleeve 3 to be inserted, but prevents the metal ring 4 from being inserted. A tubular portion having a hollow portion dimensioned as described above, and a mounting hole 8 for fixing the support fitting 6 to the screw hole 11 of the rotating body 10 with a screw 9.

The support metal fitting 6 configured as described above is fixed to the screw hole 11 of the rotating body 10 by the screw 9, and then the thread body 2 is supported via the slit 7 as shown in FIGS. 6, 7 and 8. It is put in the hollow part of the metal fitting 6 (see FIG. 6). Then, the thread body 2 is pulled upward to insert the sleeve 3 into the hollow portion of the support fitting 6 (see FIG. 7), and the thread body 2 is pulled further upward so that the metal ring 4 is engaged with the lower end of the hollow portion. By doing so (see FIG. 8), the thread assembly 1 is attached to the rotating body 10.

Here, by appropriately selecting the screw hole 11 of the rotating body 10 to which the support fitting 6 is fixed, the overhanging height of the yarn body 2 of the yarn assembly 1 during the cutting operation can be adjusted. For example, as compared with the case where the thread assembly 1 is attached to the support fittings 6 of the pair of screw holes 11 facing each other in the axial direction, the support fittings 6 of the pair of screw holes 11 which are in a positional relationship displaced from each other in the circumferential direction. When the thread assembly 1 is attached (attached state in FIG. 1), the overhanging height of the thread body 2 becomes lower. Further, compared to when the thread assembly 1 is attached to the support fittings 6 of the screw holes 11 at both axial ends of the rotating body 10, at least one end of the thread assembly 1 is attached to the support fitting 6 of the screw hole 11 at the axially intermediate position. The overhanging height of the knitting yarn main body 2 when attached is higher.

When the thread body 2 is cut, the metal ring 4 is moved downward to remove the thread assembly 1 from the support fitting 6, and the new thread assembly 1 is attached in the same manner as described above. Done.

FIG. 9 shows a beard cutting thread according to another embodiment of the present invention, which is arranged on the reel-shaped rotating body 12 in the conventional beard cutting apparatus, that is, on the outer peripheral portion thereof at equal intervals in the circumferential direction. 1 shows a beard cutting thread suitable for use in a reel-shaped rotating body 12 formed by connecting a pair of circular side plates 13 having holes 17 by a drive shaft 14.

In the beard cutting thread in this embodiment, the mounting hole of the support fitting 15 is perpendicular to the axial direction of the tubular portion, and the support fitting 15 is a hole of the rotating body 12 by means of the screw 9 and the nut 16. Substantially the same as the previous embodiment, except that it is attached to 17. Also, the thread assembly is attached to the support fitting 15 in substantially the same manner as in the above embodiment, as shown in FIGS.

[0018]

[Effect of the device]

 According to the present invention, since the thread main body is formed to have a predetermined length, it is not necessary to adjust the length at the time of replacement, and the conventional cutting thread of unequal length is provided. Therefore, it is possible to reliably prevent problems such as damage to the radish if it is too long and the presence of passive yarn if it is too short.

Further, by inserting the sleeve of the thread assembly into the support fitting and engaging the metal ring, the thread assembly can be attached to the rotating body, and the metal ring can be moved to move the sleeve. Since the thread assembly can be removed by pulling it out, the attachment and replacement of the beard cutting thread can be performed easily and in a short time.

Furthermore, since the sleeves at both ends of the thread body are configured to be joined to the support fitting, it is possible to prevent the thread body from directly contacting the support fitting and being easily cut, and to prevent the thread body from being cut during the cutting operation. The sleeve acts as a buffer against the impact force of the sleeve, and the metal ring that secures the sleeve to the thread body does not require any extra material to substantially engage with the support metal fittings. Since the load on the metal support can be reduced, the durability of the root cutting thread can be dramatically improved.

[0021] In addition, since the rotating body is made of a cylindrical member, and the support metal fittings can be fixed to the circumferentially and axially spaced positions, the root cutting made at a constant length. The overhang height during thread cutting work can be adjusted as required, and it can also be applied to conventional rotating bodies simply by changing the mounting hole direction of the support fittings.
