Description

[Detailed description of the invention]

[Field of Industrial Application] This invention relates to hanging pins used for the cultivation of shellfish and for securing young shellfish to hanging ropes. This product relates to hanging pins used to hang young molluscs from hanging ropes in the cultivation of bivalve molluscs such as Akoya molluscs.

BACKGROUND OF THE INVENTION Shellfish farming has been practiced not only in Japan but also around the world for a long time. For example, Ako and shellfish are cultivated for the purpose of collecting pearls. Aquaculture is a natural method in which young shellfish are produced in seawater and grown into adult shellfish. For this purpose, in the past, young shellfish were placed in a large box or basket, tied to a hanging rope, placed in the sea, and one end of the hanging rope was tied to a floating raft. Alternatively, you can set up a net bag at a convenient location on the hanging rope, place the young shellfish inside each bag, and culture them in the sea. The young molluscs were tied to the hanging rope by hooking the young molluscs onto it and tying the others to the hanging rope. Because shellfish farming must be carried out in the sea for about four years, other shellfish and seaweed adhere to the outer walls of the box-shaped or cage-shaped structures, and thin wires are oxidized and damaged by salt. It was getting worse. As a result, there was a high risk that the young shellfish would not receive enough oxygen and nutrients, or that the shellfish would fall to the sea floor.

[Problem to be solved] With conventional technology, young mollusks are blocked from absorbing oxygen and nutrients by seaweed and other molluscs, resulting in a large number of dead mollusks or poorly developed molluscs. Furthermore, even if you use a thin wire to hook and lower young shellfish, there is a risk that the metal will be corroded and damaged by the oxidation of salt in the seawater, and the shellfish will come off the wire. there were. Therefore, it is possible to easily and easily lock young shellfish, and to easily and easily lock the young shellfish to a fishing line.
The purpose is to provide a suspension pin for aquaculture shellfish that can be safely used for long periods of time, distributes oxygen and nutrients evenly, prevents shellfish from falling or coming off, and is easy to use.

[Means for Solving the Problems] Therefore, in order to prevent the previous drawbacks and to simply and easily hold young shellfish on a fishing line, we have developed a trunk core,
In a hanging pin consisting of a locking piece and a projection piece, elastic sharp locking pieces are provided at both ends of the elastic stem core,
Further, a plurality of elastic sharp protruding pieces are provided on the side wall of the central part of the stem core, and the stem core, the locking piece, and the protruding piece are integrally formed. Both ends of the lowering pin and the stem core are made sharp, and from the sharp end,
This problem can be solved by using a hanging pin characterized by having a locking piece provided on the side wall of the appropriate distance part. The present invention seeks to provide such a hanging pin that has not been seen before.

Embodiments Hereinafter, embodiments of the present invention will be explained based on the drawings. 1 and 2 are overall views of the hanging pin according to this embodiment. FIG. 1 is an overall view of the case in which the stem end does not protrude to the outside of the locking piece, and FIG. 2 is an overall view of the case in which the stem end protrudes from the outside of the locking piece. (1) is the trunk core. This trunk core (1) is made of an elastic member such as a synthetic resin material. Its shape may be square or circular. Therefore, even slight bending will not cause damage or breakage. (2) (2') is a locking piece whose tip is formed into a sharp corner or needle shape and is provided on the end side of the trunk core (1). The locking pieces (2) (2') are provided at both ends of the trunk core (1), and are provided facing each other in the same shape on both end sides. For example, in this embodiment, the locking piece (2)
(2') are provided facing each other in the same shape at both ends of the trunk core (1). Furthermore, the locking pieces (2) (2') may have a shape in which the locking pieces (2) (2') are removed, or vice versa. It is. The locking pieces (2) (2') are preferably made of an elastic synthetic resin material, similar to the trunk core (1), and are formed integrally with the trunk core (1). However, it is also possible to attach them by gluing or other methods instead of forming them integrally. (3) (3') is a protruding piece. The projecting pieces (3) (3') are provided facing each other in the same shape on the central side wall of the trunk core (1). This protruding piece (3
) (3') also has a sharp corner or needle-like tip, similar to the locking pieces (2) and (2'). Its size is slightly smaller than that of the locking pieces (2) (2'). These protruding pieces (3) (3') do not necessarily have to have the shape of the example, but they can also have a shape other than the protruding pieces (3) (3'). It may have any shape, and it can be made by considering the balance of the shape with the locking pieces (2) (2'). It is preferable that the protruding pieces (3) (3') are also made of a synthetic resin material like the trunk core (1) and the locking pieces (2) (2'). It is also formed integrally with these. However, it is not always necessary to form them integrally, and the protruding pieces (3) (3') can also be attached by adhesion or other methods. In addition, (1') in Fig. 2 is the trunk core (
Both ends of 1) protrude from the locking pieces (2) (2') and are sharp corners or needle-like ends of the trunk core. In other words, the locking pieces (2) (2') are not necessarily connected to the trunk core (1).
It is not necessary to provide a locking piece (2) on both ends of the stem core (1) with both ends sharp and a locking piece (2) slightly inward from the end of the stem core (1).
) (2') can also be provided. 3, 4 and 5 are general views showing the use of the hanging pin according to the invention. FIG. 3 is an overall view of how the hanging pin is penetrated and fixed to the hanging rope, FIG. 4 is an overall view of how the hanging pin is penetrated and fixed to the hanging rope, and FIG. FIG. 2 is an overall view showing a state in which a young shellfish is secured to a hanging pin that is secured through a hanging rope. To use this hanging pin, first press the locking pieces (2) (2') as shown in Figure 3, and then pass either end of the trunk core (1) through the hanging rope (4). Lock and then pull this hanging pin so that the hanging rope (4) is fitted between the protruding pieces (3) (3') of the hanging pin. In this case, it is convenient that both ends of the trunk core (1) are sharp (1') so that one end of the hanging pin can easily pass through the hanging rope (4). (4) is a hanging rope. By doing this, the protruding pieces (3) (3') serve as stoppers, and the hanging pins are connected to the hanging rope (4).
It doesn't come off easily. This is illustrated in FIG. The protruding pieces (3) (3') are the hanging rope (4)
Since it opens like a tulip on the outside, this acts as a stopper and the hanging pin will not come off from the hanging rope (4). The required number of hanging pins to be attached to this hanging rope (4) will be attached at convenient locations. (5) is a young shellfish. To attach the young shellfish (5) to the hanging pin attached in this way, press the locking pieces (2) (2') and attach the stem core (1).
are brought into contact with the oyster shell (5), and the two are brought together and passed through the hole provided in the ear of the young mollusc (5). A hole is provided in the ear portion of the young shellfish (5). After penetration, locking piece (2) (2'
) easily returns to its original state, thereby locking the young mollusk to the locking pieces (2) (2'). In this way, the young shellfish (5) can be easily secured to the hanging rope (4). Incidentally, the growing shellfish can be easily removed from the hanging pin by cutting the hanging pin at the required part using scissors or the like.

[Effects of the Invention] The invention configured as described above not only allows the hanging pin to be easily and easily locked to the hanging rope, but also enables young shellfish to be easily and easily penetrated and locked to the hanging pin. This allows many young shellfish to be easily attached to a hanging rope. In addition, since each young shellfish can be attached to a hanging rope as an individual, the supply of oxygen and nutrients to the young shellfish in the sea is good, and since it is made of synthetic resin material, it does not rot. It is economical and inexpensive.
