DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspension locking pin for suspending and raising a scallop scallop, and more particularly to a tidal resistance and a wave resistance added to a scallop adult growing and expanding as the scallop is grown. The present invention relates to a hanging lock pin for scallop cultivation, which is easy to prevent from falling off due to the scallop and is easy to pinch.

[0002]

2. Description of the Related Art Scallops are enormously consumed because they can be cooked in various ways in addition to their unique flavor and umami.
Behind this is the fact that the advancement of intermediate breeding and main breeding (main cultivation) techniques together with the establishment of natural seedling collection technology has contributed. By the way, natural scallop scallops are cultivated in healthy seedlings and grown to a shell length that can be used for consumption. It is broadly classified as a means of managing and breeding so-called main breeding (main cultivation) using facilities and materials. Not only is the production of fish catches unstable due to the slow growth, death, or damage to benthic animals, and the market price is disadvantageous because the scallop contains sand and mud.

[0003] On the other hand, in a means for managing and growing by drooping in the sea, since the dripping is performed on the luminous layer in the shallow sea, it is not possible to grow in a wide range of sea area without being restricted by the conditions of water depth and sediment. Not only that, the euphotic layer that is hung down is rich in animal and phytoplankton, organic salts, and other scallop foods, and is less harmful to benthic animals. From what is possible,
In recent years, such management training has increased remarkably.

[0004] In this management and training, the ear hanging training and the round basket,
Although a wide variety of cages such as Zabuton cages and pocket nets, houses and condominiums are employed, ear-hung rearing is extremely inexpensive for hanging materials. Because it is possible to grow up to three to four times the amount of breeding, pocket nets, houses and condominiums, etc., this method is very suitable especially for small-scale producers. The producers have adopted.

However, as shown in FIG. 6, the ear-hung cultivation at present is approximately 1.2 to 1.5 on the shell ear A of the scallop larvae grown with healthy seedlings.
A through hole B having a diameter of 1 mm is formed, and a synthetic resin such as a tough and rigid polyamide resin is used. At the center thereof, a hanging pin D which is pierced and pinched with an appropriate hanging rope C at a required interval is provided. The holding projections E, E protruding outward so as to be pinched and held by C, and through holes formed in the shell ears A of the scallop juveniles near both ends of the hanging pins D. B, and using hanging pins D provided with barbs F, F, which are inclined and project outward toward the center so that the inserted scallop does not fall off, and the hanging ropes are provided at required intervals. , And the scallop is inserted and held at both ends of the hanging pin D so as to hang down.

[0006] However, the shell length of the scallop used for raising ears is about 4 to 5 cm at most, and the shell length of the adult scallop supplied to the market by this breeding is about 10 cm.
The purpose is to grow up to about 15 cm,
Furthermore, since the ear hanging growth is suspended in a shallow sea area, scallops being grown are provided with tide resistance and wave resistance from multiple directions, and are added as the shell length is increased due to growth. The tidal current resistance and the wave resistance are increased, and the result is about 5 to 10 times that of the adult scallop compared to the young scallop. As a result, the additional force due to the increased tide resistance and wave resistance is repeatedly applied to the return pins F, F of the suspension pins D through the insertion holes of the scallop shell ears, and the return pins F, F have strength. The scallop falls off and breaks due to fatigue, and the scallop falls off and escapes. As the shell length increases, about 20 to 30% of the scallop escapes at present. Therefore, the economic damage is enormous, and the solution of this is the top priority in ear-hung rearing. In order to solve this problem, it has been attempted to replace the material forming the suspension pin D with a material such as a conventional polyamide resin having high toughness and rigidity and a material such as polypropylene which is strong and lightweight and has excellent flexibility and bending fatigue resistance. However, in the configuration of the return F, F as in the present situation, not only the effect of preventing breakage and bowl bending is not exhibited, but also the use of the rigid material, a holding projection for holding and holding the hanging rope C. There is also a problem that the rigidity of E and E is increased and it is difficult to pinch and pierce.

[0007]

SUMMARY OF THE INVENTION In view of this situation, the present inventors have conducted intensive studies and, as a result, have arrived at the present invention. The present invention provides high catch production by securely locking and holding a scallop to be ear-hung and raised until catching. It is an object of the present invention to provide a scallop cultivation suspension locking pin which enables the scallop breeding and is excellent in the workability of being pinched to a hanging rope.

[0008]

The technical means used in the present invention to solve the above-mentioned problems is that a pin member integrally formed of a synthetic resin material is provided with a hanging rope and a pinch fixed at the center. In order to achieve this, pinching and fixing claws are provided so as to protrude outward so as to face each other at a required interval, and both ends of this pin material are sharpened so that they can be easily inserted into the hanging rope. From the center position as appropriate from both side ends of the pin material, the tip is inclined outward toward the center side so that the scallop inserted into and locked is securely held until the fishing season. The height of the tip is 2 to 5 times as large as the diameter of the pin material. Joined,
Further, the diameter of the pin material corresponding to the length to be deformed and joined so as not to increase the substantial diameter of the pin material is reduced to 1/2 to 2/3 to form a pin material small diameter portion, and A locking piece having a thickness corresponding to the diameter reduction is branched and extended from the distal end side of the pin material narrow diameter section, and the pin material narrow diameter section deformed and joined to an inner part near the tip of the locking piece. A pin material having a configuration in which an insertion locking claw connected to a substantially central portion by a bendable reinforcing piece that is bendable is formed, or a pin material having a small diameter that is deformably joined to an inner portion near the tip of the locking piece of the insertion locking claw. And a substantially central portion of the portion is connected by a deformable reinforcing piece. Further, instead of the pinching and fixing claws, the pin material is moved toward the center with a required interval at the center of the pin material. A configuration in which a clamping fixing taper and a clamping fixing groove are formed in which the diameter is sequentially increased, or a required interval is set at the center of the pin material.且 each other in which resides on the configuration of the lower locking pins hanging scallops for fostering clamped and held recess Hasame pins material fraction size is so formed toward the center.

[0009]

Since the present invention has the above-mentioned structure, it has the following functions. That is, both ends of the pin material are formed integrally using a synthetic resin material, and both ends of the pin material are sharpened. The height of the tip is equivalent to 2 to 5 times the diameter of the pin material, and it is deformed when it is inserted into the insertion hole of the scallop and the actual diameter increases when joining with the pin material. The tip of the pin material thin portion having a thickness corresponding to the diameter reduction of the pin material thin portion in which the diameter of the pin material at the portion to be deformed and joined is reduced to 1/2 to 2/3. A locking piece is branched and extended from the side, and an inner portion near the tip of the locking piece and a substantially central portion of the pin material small-diameter portion are connected by a bendable or deformable reinforcing piece. Since the locking claw is formed, a flexible synthetic resin material with excellent bending fatigue resistance and moldability is used. The pinch fixing claw, which is formed to project outward at an angle from the center of the pin material at a required interval to face each other, is easily deformed when piercing into the drooping rope. It can be done efficiently. In addition, when the scallop is inserted and locked, the pin ends are sharpened on both sides so that the pin can be easily inserted into the insertion hole of the scallop, and the insertion stress causes the lock to be inclined outward toward the center side. The bending piece is bent or the reinforcing piece is bent or the reinforcing piece is deformed due to deformation of the locking piece so that the locking piece becomes thin. The scallop is deformed so as to be joined to the diameter part, and the scallop is inserted.The scallop is also inserted through the small diameter part of the pin material smaller than the diameter of the insertion hole. When the reinforcing piece or the reinforcing piece is restored, the locking piece is also inclined and deployed again toward the center side outward, so that the inserted scallop is prevented from falling off.

[0010] During the growth period of the scallop inserted and locked, tidal resistance and wave resistance are repeatedly applied, and even when this additional force is applied to the insertion locking claw through the insertion hole of the scallop, bending reinforcement is also provided. The piece is bent and stretched or the reinforcing piece is deformed to absorb and relax, so that breakage of the insertion locking claw and bowl bending are also prevented. In addition, in the present invention, instead of the pinching fixing claw, a pinning fixing taper and a pinching fixing groove are formed at the center of the pin material at a required interval and the diameter of the pin material is gradually increased toward the center. In the configuration described above, the twist or braid is expanded along the pinch fixing taper by piercing and inserting into the twist or braid of the hanging rope, and the expansion force is released by the clamping fixing groove, and the twist is twisted. The hanging ropes are clamped and fixed on the peripheral surface of the tapered wall together with the restoration of the eyes and braids, so that a stable clamping and fixing is achieved. In the configuration in which the squeezing fixed concave portion is formed, the twisting force of the hanging rope and the expanding force of the braid at the time of piercing and stabbing in the stab fixing concave portion are released, while being able to be pinched with a slight piercing pinching input, Extremely efficient clamping and fixing due to its restoring force Nashieru.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an explanatory view of the present invention, and FIGS. 2 and 3 are explanatory views of the present invention having different insertion locking claws. The present invention is formed integrally with a synthetic resin material by an injection molding method or a blow molding method. The synthetic resin material to be used is a wide range such as a polyolefin resin, a polyamide resin, a polyester resin or an ABS resin. Can be used, but a resin material of a grade excellent in toughness, flexibility and bending fatigue resistance in addition to inexpensiveness and excellent moldability is desired. The length and thickness of the pin material 1 as a whole, ie, the so-called diameter, are determined in consideration of the shell length and weight of the scallop to be hung and raised. The shell length of the shell is about 4 to 5 cm, and the shell length of the scallop is about 10 to 15 cm at the time of catching.
In such a case, the length of the pin material 1 is approximately 5 to 7 cm.
In addition, one having a diameter of about 1.2 to 1.5 mm is used.

In the center of the pin material 1, pinching fixing claws 2, 2 are formed so as to face each other at a predetermined interval and to stab outward. In this case, the distance between the fixing nails 2 is different depending on the diameter of the hanging rope C used. However, in the case of a commonly used hanging rope C having a diameter of 7 mm, the tip 2A of the fixing nails 2 is used. , 2A are formed at a distance of 7 to 8 mm.
Is pressed against each other, and the distance between the lower ends 2B and 2B of the fixing claws 2 is set at the tip 2 thereof.
The clamp fixing claws 2 are formed so as to be approximately 50 to 80% wider than the interval between A and 2A so that they are inclined. Further, if the pinching fixing claws 2 and 2 are formed too thick, the rigidity increases and it becomes difficult to pierce and pinch. Therefore, the diameter of the pin material 1 is desirably about 30 to 50%.

Both ends 3 and 3 of the pin material 1 are sharpened so that they can be easily pierced into the braids and braids of the hanging rope C when the pin is fixed. In the side position, the tip is inclined and deployed outward toward the center side so that the scallop inserted and locked is securely held until the fishing season, and the height of the tip 4A is adjusted to the pin position. When the pin 1 is inserted into the insertion hole B of the scallop scallop at a height corresponding to at least twice and at most 5 times the divisional diameter of the pin 1, the pin 1 is deformed freely. When joining with pin material 1
The diameter of the pin member 1 corresponding to the length to be deformed and joined is reduced to 1/2 to 2 /
3 to form a pin material small diameter portion 1A, and a locking piece 4B having a thickness corresponding to the diameter reduction is branched and extended from the tip side of the pin material small diameter portion 1A, and A penetrating locking claw 4 is formed in which the inner portion 4C near the tip of the locking piece and the substantially central portion 1B of the pin material small-diameter portion 1A deformably joined are connected by a bending reinforcing piece 4D that can be bent freely. ing.

In such a case, the bending reinforcing piece 4D is subjected to an additional force such that the insertion locking claw 4 is not broken or bowled by the additional force of the tide resistance and the wave resistance applied to the scallop grown by being inserted and locked. And has the role of reinforcing the insertion locking claw 4 and constantly tilting and deploying the locking piece 4B so that the scallop inserted and locked is securely locked. Naturally, a material having excellent elasticity and bending fatigue resistance is desired. As for the bending of the bending reinforcing piece 4D, as shown in FIG. 1, the bending portion is bent toward the center of the pin material small diameter portion 1A from the inner portion 4C near the tip of the locking piece and connected to the substantially central portion 1B of the pin material small diameter portion 1A. In this configuration, as shown in FIG. 2, a configuration may be used in which the inner side portion 4C near the distal end of the locking piece is bent toward the distal end side of the pin material small-diameter portion 1A and connected to the substantially central portion 1B of the pin material small-diameter portion 1A. .

Further, the insertion locking claw 4 is provided with these bending reinforcing pieces 4D.
As shown in FIG.
A configuration in which C and the substantially central portion 1B of the pin material small-diameter portion 1A are connected by a deformable reinforcing piece 40D can also be used practically. The bending reinforcing piece 4D and the reinforcing piece 40D
When insertion stress is applied when inserting the scallop into the scallop, the insertion piece 4B is bent or deformed freely, and the locking piece 4B that is inclined and deployed is joined to the pin material small-diameter portion 1A, and the insertion stress is removed. In this case, the locking piece 4B is tilted and deployed again by using the restoring force, and the insertion locking claw 4, especially the locking piece 4B is added due to the additional force such as tide resistance and wave resistance applied to the growing scallop. It is desirable that the bending reinforcing piece 4D and the reinforcing piece 40D be formed to have a thickness of at least 0.2 mm or more, although it depends on the material used. It is desirable that the reinforcing piece 40D be formed such that the substantial length of the reinforcing piece 40D when extended is such that the locking piece 4B is held at an inclination angle of approximately 45 to 70 degrees with respect to the axis of the pin material 1.

As shown in the figure, a pinch fixing taper 5 is formed at the center of the pin material 1 with a required interval and the diameter of the pin material is gradually increased toward the center. In this configuration, a pin material 1 having a sharpened side end is pierced and inserted into a twist or a braid of the hanging rope C in this configuration. As a result, the twist or the braid is expanded by the sandwiching fixing taper 5, and the expanding force is removed by the sandwiching fixing groove 5A, so that the expanded twist or the braid is restored, and the sandwiching fixing taper peripheral wall is restored. The drooping rope C is stably fixed and fixed in the whole 5B. In such a case, the height of the pinch fixing tapered peripheral wall 5B from the outer surface of the pinch fixing groove 5A is desirably formed to be 2 mm or more, which is convenient for ensuring the pinch fixing.

Further, as a means for easily and stably fixing the piercing into the drooping rope C, as shown in FIG. 1 has a configuration in which a clamping fixing concave portion 50 having a reduced diameter is formed.
