Description

[Detailed Description of the Invention] The present invention relates to a locking device for cultivating scallops, which is used when culturing scallops by attaching them to a line or rope and suspending them in the sea.

In the cultivation of scallops, young scallops are attached to a hanging line or rope, and the line or rope is suspended into the sea, and cultured in this state for, for example, several years.

The problems in cultivating scallops are how easily the young scallops can be suspended from a rope or rope, and how to hold the young scallops so that they do not fall off once they have been suspended. That's true.

The work of suspending young shellfish from a rope or rope is
Preparation work is necessary as it will be carried out in an extremely short period of time. In this preparatory work, one end of a certain length of rope is tied in advance to a rope or rope.
The other end of the scallop is inserted into a hole in the ear of the scallop, and the end is tied to create an enlarged part to prevent the scallop from falling out.

However, this method of attaching scallops to lines or ropes with tegus is a complicated process, and since tegus has considerable elasticity, it can only be done successfully by a skilled person. Also,
If the tegus are not tied very well, there is a risk that the tegus knots will loosen during the long cultivation period and the young shellfish will fall off the line or rope, which has the disadvantage of reducing the efficiency of aquaculture.

The present invention aims to improve the problems associated with attaching young scallops to a line or rope during conventional scallop farming. It is an object of the present invention to provide a locking device for cultivating scallops that can be used for cultivating scallops.

Furthermore, another objective is to simplify the work so that preparatory work can be omitted, or even if it cannot be omitted, the work can be simplified;
Moreover, it is an object of the present invention to provide a locking device for cultivating scallops that can securely attach young scallops to a rope or rope.

In order to achieve this purpose, the present invention includes a first fixing part that is inserted into a small hole in the ear of the scallop so as not to escape, a rod-like part with one end fixed to the first fixing part, and a rod-like part that is fixed at one end to the first fixing part. The second fixing part is provided at the other end of the rod-shaped part, and the first fixing part has an arrow-shaped detachment prevention piece that is bifurcated from the tip toward the rod-shaped part; The second fixing part is composed of two or more angular pieces, and at least one first angular piece projects obliquely from the tip of the second fixing part toward the first fixing part, at least 1
The second angular pieces are slanted and protruded toward the distal end side of the second fixing part with an interval that allows the rope or rope to be sandwiched between the first angular pieces,
The first and second horn-shaped pieces are configured to hold a rope or rope in a fixed manner so as not to escape, and are entirely integrally molded from synthetic resin. be.

Hereinafter, the configuration of the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a front view of a locking device according to a first embodiment of the present invention, in which the locking device F includes a first fixing part 1 for fixing a young shellfish, a rod-shaped part 2 following this, and the rod-shaped part. and a second fixing part 3 formed at one end of the second fixing part 2. The fastener F is integrally molded from synthetic resin.

A first fixing part 1, which is a part for fixing young scallops, is provided with an arrowhead-shaped detachment prevention piece 1a which is bifurcated from the tip toward the rod-shaped part 2.
This slip-off prevention piece 1a is formed to open laterally from the rod-shaped part 2, and when the first fixing part 1 is inserted into the ear hole of the young shellfish, it narrows, and after insertion, it becomes elastic. It has the function of expanding to prevent young shellfish from falling out. The holes for the ears of young shellfish must be small so as not to inhibit the growth of young shellfish.
If a large hole is made in the ear of a young shellfish, the growth of the young shellfish will be inhibited and there is a risk that the young shellfish may die. In the present invention, the first fixing portion 1 is provided with an arrowhead-shaped slip-off prevention piece 1a so that it can be inserted into this small hole. Thereby, the first fixing part 1 can be inserted into a small hole in the ear of a young shellfish, and after insertion, it is possible to prevent the young shellfish from coming off.

Moreover, the second fixing part 3 is a part fixed to a rope or a rope, and this part has a second square piece 3a,
The first angular pieces 3b are formed to protrude diagonally so as to face each other at a distance that allows the rope or rope to be sandwiched therebetween. The second angular piece 3a faces toward the tip side of the second fixing part 3, and the first angular piece 3b
is facing the first fixed part 1 side.

Therefore, when the first angular piece 3b moves in the direction of the arrow A and plunges into the rope or rope 4 shown by the dotted line, the first angular piece 3b is in the closed state. It can be easily inserted into a rope or rope 4. On the other hand, the second angular piece 3a expands in the direction of the arrow A so that it is prevented from passing through, so the rope or rope 4 shown by the dotted line
It is not possible to pass through this rope or rope 4 as it is locked by the rope. This makes it possible to secure the rope or rope 4 between the first angular piece 3b and the second angular piece 3a and to hold it therein so as not to escape.

In this way, in the locking tool of the present invention, the second angular piece 3a and the first angular piece 3 are provided at one end of the rod-shaped body 2.
b are formed to face each other, the first angular piece 3b is formed in the direction of closing when inserted into the rope or rope 4, and the second angular piece 3a is formed in the direction of opening in the insertion direction. Therefore, when the second fixing part 3 is inserted into the rope or rope 4, the first angular piece 3b is easily inserted, but the second angular piece 3a cannot be inserted. Therefore, the rope or rope 4 inserted between the second angular piece 3a and the first angular piece 3b will no longer come off.

As mentioned above, the first fixing part 1 is arrow-shaped, so if a young scallop to be fixed is inserted in the direction of arrow B, the young scallop can be easily fixed to the first fixing part 1, and it will come out. can be prevented. Also,
In the second fixing part 3, as described above, the rope or rope 4 is fixed between the second square piece 3a and the first square piece 3b and is held between them so as not to escape. The fixed state between the stopper F and the rope or rope 4 is ensured.

FIG. 2 shows a second embodiment of the present invention, in which a second angular piece 3a facing outward is provided, and a first angular piece 3a facing inward is provided.
b and 3c are provided. In this example,
Although one of the square pieces 3a of the locking device F shown in FIG. 1 is omitted, the square piece 3c is different from the square pieces 3a and 3.
Since the square piece 3c is located between the rope 4 and the rope 4, the square piece 3c is often inserted into the rope or rope 4, thereby making the locking condition quite strong.

FIG. 3 is a perspective view showing the state in which the locking device for cultivating scallops according to the present invention is used. In use, first, the second fixing part 3 of the fastener F is inserted into the rope or rope 4 as shown in the upper part of FIG. Normally, in this state, the fish are transported to a fish farm and prepared for suspension into the sea.

After being prepared in this way, the first fixing part 1 is inserted into a small hole 21 made in the ear of the young shellfish 20 which is the object to be fixed.
and fix it as shown in the lower part of Fig. 3.

FIG. 4 is a front view showing a third embodiment, in which the base 30 of the first square piece 3B of the fastener F is formed to be rounded. In this locking device F, the rope or rope 4 is usually inserted through the first fixing portion 1 . Moreover, since this locking tool F does not have a protruding portion formed on the second fixing portion 3 side, it is advantageous in that accidents such as injury during work can be prevented from occurring.

FIG. 5 shows a fourth embodiment, which is characterized in that the square pieces 3a and 3B protrude to opposite sides.

FIG. 6 shows a fifth embodiment, in which the second embodiment shown in FIG.
The shape is almost the same as that of the embodiment.

FIG. 7 shows a sixth embodiment, which is a modification of the second fixing part 3 shown in FIG.

In the embodiments shown in FIGS. 4 to 7, since no protrusion is formed on the second fixing part 3 side, it is possible to prevent injury during work, but the first Since it has to be inserted into the rope or rope 4 from the fixed part 1 side, it takes some time to attach it to the rope or the like, but the features of the present invention can be fully demonstrated.

In addition, when fixing the fastener F according to the present invention to the rope or rope 4, there are two methods: inserting from the second fixing part 3 as described above, and inserting from the first fixing part 1 to the second fixing part 3. There is a method of inserting it from the side, but according to the experience of the present inventors, it seems to be easier to insert it into the rope or rope 4 from the first fixing part 1 side. However, the method of fixing the locking tool F is not particularly limited, and may be carried out in a manner that is easy for the operator.

Since the locking device for cultivating scallops of the present invention is constructed as described above, the present invention can achieve the following effects.

In preparation for scallop farming, it is necessary to attach one end of the locking device to the rope or rope, but with the locking device of the present invention, the second fixing part can be fixed by simply inserting it into the rope or rope. , does not require much time for preparation work, and does not require skill.

Furthermore, when hanging young scallops in the sea, it can be easily attached by simply inserting the first fixing part into the small hole made in the ears of the young scallops. does not require skill.

In this way, both the preparation work and the work of attaching the young shellfish can be done with one touch, resulting in extremely high work efficiency.

Furthermore, it is harder for young shellfish to fall off than with a locking tool, so
Cultivation efficiency is also good.

Since the locking tool is integrally molded from synthetic resin, it has excellent productivity and can be provided at low cost.

The first fixing part has an arrow-shaped piece to prevent it from coming off, which is bifurcated from the tip toward the rod-shaped part. When inserting into the hole, the prevention piece is pressed and comes into close contact with the rod-shaped part, making insertion extremely easy.After insertion, the prevention piece elastically opens, so the rod-shaped part can be reversed. Even if it is pulled in the direction, the preventing piece resists the pulling force, so the locking tool will not slip out from the small hole provided in the ear of the young shellfish.

Since the space between the first horn piece and the second horn piece is such that the rope or rope can be sandwiched between them, it is possible to fix the rope or rope between them and hold it so that it does not escape. can. Therefore, since the locking device and the rope or rope are securely fixed, it is possible to hold the young scallops in a fixed position during cultivation, which prevents the young scallops from coming into contact with each other and pressing against each other during cultivation. This does not cause any inconvenience such as inhibiting the growth of young shellfish or causing death of young shellfish.
