Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rotating plate for a brush cutter that rotates a cord mounted on the rotating plate to mow the grass. In particular, it relates to a turntable for a brush cutter that uses a relatively short code for exchange and mowing.

Furthermore, the present invention relates to a rotary disk which allows the code itself to be fixed to the rotary disk as it is without providing any fixing means such as metal fittings, knots, and bulges at the inner end of the code.

[0003]

[Prior art]

 In this type of brush cutter, a length of 80 to 150 mm on one side of the code is generally used by pulling it out of the turntable, so that a relatively short code is attached to the turntable.

Therefore, it is unavoidable that the code is consumed in a relatively short time during mowing, and the code must be replaced frequently. It is well known that this code replacement work is troublesome and hinders the improvement of work efficiency for workers.

Therefore, various kinds of inventions and inventions have been made so that the code can be easily attached and detached.

[0006] For example, there is a device described in Japanese Utility Model Laid-Open No. 63-31734.

[0007] In this example, notches are provided in an arc shape toward the inside at four equally spaced locations on the outer peripheral edge of the rotating disk body, and relatively large circular holes are provided inside the notches so as to be adjacent to these notches. In addition, a pair of code locking holes are provided between the pair of circular holes and relatively close to the peripheral edge of the main body of the rotary disk which is not provided with a notch. is there.

Then, the code is inserted into the pair of code locking holes from the back surface of the rotary disk, and the code is introduced into the surface of the rotary disk body, and the rotary disk is inserted through the circular hole. It has been extended and distributed for use on both sides of the back of the main unit.

However, in this conventional example, since the code mounting means is single, the method of using the code is limited to a single method, and when the code is used for a certain purpose, it must be immediately discarded. Although there is an advantage that the code can be easily replaced without providing a fixing means at the end of the code, the code is wasted and the code is still frequently replaced. I have to do it.

[0010]

[Problems to be solved by the device]

 The problem to be solved by this invention is due to the fact that there is only one means for mounting the code. -The length of the cord cannot be adjusted freely.

[0018]

Example 1 This example is shown in FIGS. 1 to 9. As is known, the turntable body 10 is rotated by the drive shaft 32 of the brush cutter body 30 (see FIGS. 1 and 2).

Usually, two or four cords 34 are mounted in the turntable body 10, and the outer side of the cord 34 has different kinds of plants, hardness and hardness, or a difference in the degree of growing plants which varies depending on the season. Depending on the purpose of use, a length of about 80 to 150 mm is generally used by pulling it out of the turntable body 10 (see FIGS. 3, 6, 7, and 8).

At the outer peripheral edge of the turntable body 10, the inner ends 34a and 34b of the cord 34 are inserted into the turntable body 10 at the time of use, or from the inside of the turntable body 10 for use or replacement. There are four cord inlets / outlets 14a, 14b, 14c, 14d for taking out the cord 34.

In this embodiment, four code inlets / outlets 14a, 14b, 14c, 14d are provided at equal intervals, and four outsides of the code 34 can be projected to the outside of the turntable body 10. However, the number is not limited to four. At least one is required, but it may be two or three, or even four or more. Further, the configurations of the code inlet / outlets 14a, 14b, 14c, 14d are the same as those conventionally known.

As is known in the center of the turntable body 10, the drive shaft 32 of the grass cutter body 30 is connected to the turntable body 10 so that the turntable body 10 can be freely rotated. Is provided.

The inner ends 34a, 34b of the cord 34 are inserted between the mounting hole 16 and the outer peripheral edge of the turntable body 10 in the circumferential direction and in the axial direction of the turntable body 10. In order to make it possible, there is a clearance for the code locking holes 18a, 18b, 18c, 18d, 18e, 18f, 18g, 18h, 18i, 18j, 18k, 18m. Unless otherwise specified, a total of 12 "18a" are provided at regular intervals (see FIG. 3).

Of course, the number of the code locking holes “18a” is not limited to twelve, and the number can be freely increased or decreased according to the application.

These code locking holes "18a" are, of course, means for fixing the inner ends 34a, 34b of the code 34 inside the turntable main body 10, and are for a large number of codes. By providing the stop hole "18a", it is possible to adjust the length of the outside of the code 34 drawn out of the rotary disk body 10.

Although details will be described later, in the drawings, for example, the code locking holes 18f and 18g located at the shortest distance to the code inlet / outlet 14c and the shortest distance to the code inlet / outlet 14a are located. The inner ends 34a and 34b of the two cords 34 are fixed by inserting the cord locking holes 18a and 18m, and the outer ends 34A and 34B of the cords 34 are adjacent to each other. It is considered that the outer side of the cord 34 can be ejected out of the main body 10 for the longest time by pulling out from the cord inlet / outlet port 14c and the cord inlet / outlet port 14a, respectively (see FIG. 6). .

On the contrary, the inner ends 34a and 34b of the two cords 34 are locked for the cords at the positions farthest from the cord inlet / outlet 14c and the cord inlet / outlet 14a. If fixed by inserting into the holes 18a, 18b and the code locking holes 18g, 18h, the outside of the code 34 can be projected out of the main body 10 for a short time. (See Figure 3).

Further, an annular guide wall 20 is provided on the inner side of the many code locking holes "18a" on the back surface of the turntable body 10 (FIGS. 2 and 3). (See FIGS. 6, 7, and 8). In this embodiment, the guide wall 20 is provided adjacent to the code locking hole "18a" on the inner side thereof and on the rear surface of the turntable body 10, but the details will be described later, but the front The inventor also plans to provide it on the outside of the code locking hole "18a" (see FIGS. 11 and 14).

As will be apparent from FIG. 2 and FIG. 3, the guide wall 20 has inner ends 34a, 34 of the cord 34 when the inner ends 34a, 34b of the cord 34 are fixed. By pressing the b-side along the guide wall 20, the code 34 can be suppressed so as not to move in the rotary disk body 10, and the code 34 can be fixed by the locking hole "18a". In addition, since the brake action is additionally exerted on the code 34, it is intended to exert the function of further firmly fixing the code 34 in the rotary table body 10. .

In FIG. 2, reference numeral “36” indicates a nut for fixing the turntable body 10 to the drive shaft 32 of the brush cutter body 30.

[0031]

[Example 1 of use of the code of Example 1]

As shown in FIG. 3, the inner end 34a of one of the cords 34 is connected to the inlet / outlet ports 14a, 14b, 14c, 14d for the cords at arbitrary positions of the rotary disc body 10, for example. 14a.

The inner end 34b of the other cord 34 is inserted into, for example, the cord inlet / outlet 14c at a remote position facing the cord inlet / outlet 14a.

The inner end 34a of one of the cords 34 is guided along the guide wall 20 while the inner end 34a of the cord 34 is engaged with the code locking hole 18h from the rear surface side of the turntable body 10. The inner end 34a of the cord 34 is pulled out to the surface side of the turntable body 10, and the inner end 34a is folded back along the surface side of the turntable body 10 as apparent from FIG. The inner end 34a is inserted into the code locking hole 18g adjacent to the code inlet / outlet 14c, and the inner end 34a is pulled out to the rear surface side of the turntable body 10.

In this way, the inner end 34 a of the cord 34 is fixed inside the turntable body 10.

As for the other code 34, it is easy to mount the two codes 34 on the same line by symmetrically performing the method of fixing the one code 34. You can understand.

In this example of use, the inner ends 34a and 34b of the code 34 are fixed by two adjacent code locking holes 18a and 18b and two code locking holes. Although it has been described that 18g and 18h are used for fixing, in this case, since the code 34 can be firmly fixed and the number of rotations of the turntable body 10 can be increased, hard plants and growing Suitable for mowing work in autumn.

The inventor naturally plans to fix the inner ends 34a and 34b of the code 34 by utilizing only one code locking hole 18h and code locking hole 18b, respectively. (See Figure 4).

In this case as well, the number of rotations of the turntable body 10 can be increased, and therefore, it is also suitable for hard grasses and grass cutting work in autumn when sufficient growth is sufficient.

Further, in order to make the cord 34 pop out of the rotary disc body 10 for a relatively long time, although not shown, the fixing position of one inner end 34a of the cord 34 is not changed. However, as is apparent from FIG. 3, one outer end 34A of the code 34 is changed from the code inlet / outlet port 14a to the code inlet / outlet port 14c. By changing the outer end 34B on the other side from the code inlet / outlet 14c to the code inlet / outlet 14a, the code 34 can be extended out of the rotary disk body 10 for a long time.

In this invention, the projecting fixing means is not provided at the inner end of the cord 34 in the conventional art, but the operation for surely fixing the fixing means will be described with reference to FIG. .

The diameter of the code locking hole "18a" is set to be slightly larger by the diameter of the code 34, and a clearance is provided, and the opening of the code locking hole "18a" is provided. Since it is provided at a constant angle without being bent, even if the fixed portion 34x of the code 34 is strongly pulled outward, the clearance causes a slight gap to the code 34. Since the fixing portion 34x swings and receives a brake operation by the opening, the free portion 34y of the code 34 does not easily come out.

Since it is expected that the opening will be relatively worn out, when the rotating disk body 10 is made of plastic, the opening should be equipped with a metal such as steel having high durability. In addition, the inventor also plans to select metal or durable plastics as the material of the rotary table body 10.

When the clearance is not sufficient, the rotational stress directly affects the code 34. When the clearance is present, the rotational stress is indirectly absorbed by the clearance.

[0045]

[Example 2 of use of code of Embodiment 1] As shown in FIG. 6, one inner end 34a of the code 34 is connected to the inlet / outlet ports 14a, 14b for the cords at arbitrary positions of the turntable body 10. 14c, 14d, for example, is inserted into the code inlet / outlet 14a.

The inner end 34b of the other code 34 is inserted into, for example, the code inlet / outlet 14c at a remote position facing the code inlet / outlet 14a.

Then, the inner end 34a side of the code 34 is inserted into the code locking hole 18a close to the code inlet / outlet 14a from the rear surface side to the front surface side of the turntable body 10, and The inner end 34a is folded back on the front surface side and the inner end 34a is inserted into the adjacent code inlet / outlet locking hole 18m, and the code 34 is fixed in the turntable body 10.

The method of fixing the other code 34 on the inner end 34b side is carried out according to the method of mounting the one code 34 described above.

In this case, although it can be said that the fixing of the code 34 is slightly weaker than that in the previous example of use, the length of the code 34 protruding from the rotary table body 10 needs to be relatively long. It is effective when there is sexuality. Although the number of revolutions of the turntable body 10 is reduced by lengthening the protrusion of the cord 34 as compared with the previous example of use, it is suitable for mowing work of flexible vegetation and vegetation at a young sprout period when growing is not sufficient.

[0050]

EXAMPLE 3 OF USE OF CODE OF EXAMPLE 1 As is apparent with reference to FIG. 7, the inner end 34a of one of the cords 34 is attached to the cord engaging hole 18i and the outer end 34A is attached to the cord. Inserted from the surface of the turntable main body 10 into the locking hole 18h for the cord, the central portion of the code 34 is fixed by the locking hole 18h for the code and the locking hole 18i for the code. The outer end 34A and the inner end 34a of the cord 34 are projected from the cord inlet / outlet 14b and the cord inlet / outlet 14a.

Although not described, the other code 34 is also symmetrically arranged according to the procedure of mounting the one code 34.

In this example of use, as can be easily understood from the above description, although the length of the cord 34 protruding from the rotary disc main body 10 is relatively short, the two cords 34 are corded at four positions. -It can be made to project from the inlet / outlet ports 14a, 14b, 14c, 14d, and there is an advantage that the two cords 34 can be utilized as the cords 34 corresponding to substantially four cords.

Therefore, when the projecting length of the code 34 may be relatively short as described above, it is expected that the capacity will be nearly doubled as compared with the above-described use example.

[0054]

[Example 4 of use of code of Embodiment 1] As is clear with reference to FIG. 8, the inner end 34a of one of the cords 34 is connected to the code locking hole 18i, and the outer end 34A is connected to the cord. It is inserted from the surface of the turntable body 10 into the locking hole 18h for the cord, and the central portion of the code 34 is fixed by the locking holes 18i and 18h for the code. The inner end 34a and the outer end 34A are projected from the cord inlet / outlets 14d and 14c.

The outer end 34 B and the inner end 34 b of the other code 34 are also projected to the outside of the turntable body 10 by the same procedure.

Thus, even in this usage example, the function of the two cords 34 can be substantially obtained as the four cords 34. Further, in this example of use, there is an advantage that the length of the cord 34 protruding to the outside of the rotary table body 10 can be set comparatively long.

[0057]

Second Embodiment The basic configurations of the second to sixth embodiments described below are common to the first embodiment. That is, in a rotary disc for a brush cutter, which is provided with a rotary disc main body 10 rotatably mounted on the brush cutter main body 30 and a code 34 on the rotary disc main body 10, a cord is attached to the outer peripheral edge of the rotary disc main body 10. -The inlets / outlets 14a, 14b, 14c, 14d for the door are provided, and a constant space is provided in the circumferential direction and in the axial direction of the rotary disc body 10 between the mounting hole at the center of the rotary disc body 10 and the outer peripheral edge. It is in agreement that a large number of code locking holes "18a" are provided for each. FIG. 10 is a rear view according to the usage example of the second embodiment. Therefore, it goes without saying that the reference numerals in the drawings are the same, and the reference numerals are the same as those in the first embodiment.

In contrast to the guide wall 20 of the above-mentioned embodiment which is annular, this embodiment is the same except that a large number of guide projections are provided.

Eight guide protrusions 35a are provided in the circumferential direction inside the code locking hole "18a". Of course, this does not mean that the number of guide protrusions 35a is limited to eight.

The cord 34 is fixed by inserting it into the locking hole 18b.

On the other hand, the outer end 34A of the cord 34 is brought into contact with the outside of the guide protrusion 35a in a circular shape and pulled out of the body 10 through the cord inlet / outlet 14a. In this case, the protruding length of the cord 34 outside the main body 10 is relatively short.

On the other hand, when the protrusion of the cord 34 to the outside of the main body 10 is lengthened, the outer end 34A of the cord 34 is pulled out by sequentially changing the cord outlets 14b, 14c, 14d and 14a. Can be implemented by

Further, by keeping the code inlet / outlet 14a constant and sequentially changing the position of the code locking hole "18a" in the circumferential direction, the code 34 that jumps out of the rotary disk main body 10 is provided. It will be readily appreciated that the length of the can be adjusted.

The length of the cord 34 can also be adjusted by introducing the cord 34 by changing the combination of the cord inlets / outlets 14a, 14b, 14c, 14d and the cord locking hole "18a". it can.

[0067]

Third Embodiment FIG. 11 is a rear view of a usage example of the third embodiment.

Eight guide protrusions 35a in this example are provided in the circumferential direction outside the code locking hole "18a". Of course, it goes without saying that it is not intended to limit the number to eight. Further, the set interval of the guide protrusion 35a is not necessarily limited to be constant.

[0069]

[Example of use of code of Example 3] The example of use of the code 34 of this example may be carried out in accordance with the example of Example 2, and the inner end 34a of the code 34 is fixed by the guide protrusion. It is carried out inside 35a.

[Effect of device]

 Since the present invention has the above-mentioned configuration, it has the following advantages. (1) A large number of code locking holes are provided at regular intervals in the circumferential direction between the mounting hole at the center of the turntable body and the outer peripheral edge and in the axial direction of the turntable body. Therefore, the length of the code protruding outside the main body of the rotating disc can be set freely according to the type of plant and the purpose and use, and the code protruding from the main body of the rotating disc is consumed and shortened. In this case, by changing the mounting position of the code without replacing the code, it is possible to lengthen and use the code that jumps out of the main body of the turntable. In addition, since an annular guide wall and a large number of protrusions are provided adjacent to a large number of code locking holes, it is possible to control the delusion of the code accommodated in the turntable body. It is possible to secure the fixing of the cord. (2) Also, since the guide wall is provided inside the guide protrusion, even a relatively long code can be preliminarily wound around the guide wall, so a short code of this type is used. A relatively long code can be adopted even in the type of brush cutter.
