Description

[Detailed Description of the Invention] (Industrial Field of Application) The aquaculture shellfish anchoring device of the present invention is suitable for anchoring and hanging scallops in, for example, scallop ear hanging culture.

(Prior Art) One of the conventional methods for cultivating scallops is ear hanging culture.

As shown in Fig. 1, this is a play rope A that is stretched underwater and a knitted rope C with scallops attached to it in advance.

To attach the scallop B to the knitted rope C, insert the synthetic resin aquaculture shell retainer D into the stitches of the knitted rope C, which is made by knitting several strings made of synthetic resin such as vinyl or nylon, as shown in Figure 3. hole F (Fig. 2).
The scallop B is passed through the aquaculture shellfish anchoring device D and tied as shown in FIG. 3 to prevent the scallop B from falling out from the aquaculture shellfish anchoring device D.

(Problem that the invention attempts to solve) However, the method described above is based on a single net rope C of 7 to 8 m.
As many as 100 to 120 aquaculture shellfish anchoring devices D must be tied together by hand one by one, and scallops must be attached to each aquaculture shellfish anchoring device D one by one, which requires a lot of work. This method has the disadvantage that it requires a large amount of manpower and time.

Therefore, the applicant of the present invention has previously developed a shellfish retaining device a for aquaculture as shown in FIG. This is provided with slip-off prevention protrusions c for locking the scallop B on both sides of an attachment part b attached to the rope C, and moreover, these protrusions gradually expand outward toward the attachment part b.

The aquaculture shellfish locking tool a can be inserted into the rope C and will not come off from the rope C, so there is no need to tie it to the rope C one by one.Also, just by inserting the scallop B to the inside of the slip-off prevention protrusion c, the scallop B can be pulled out. Therefore, there is no need to insert the scallop B and then tie the aquaculture shellfish locking device as shown in Fig. 3. Therefore, the use of this aquaculture shellfish anchoring device is very convenient in that it simplifies the work of attaching scallops.

However, this aquaculture shellfish retainer has a short total length of about 6 cm and a thin diameter of about 1 mm, so
When the scallop B is inserted into the through hole F and then pulled to the inside of the slip-off prevention protrusion c, it is difficult to grasp one longitudinal end of the aquaculture shellfish locking tool a. Therefore, there was a problem that it was difficult to pull the scallop B to the inside of the slip-off prevention protrusion c.

(Purpose of the invention) The object of the invention is to further improve the above-mentioned aquaculture shellfish anchoring tool, so that the work of hanging the aquaculture shellfish can be further simplified.

(Means for solving the problem) The aquaculture shellfish anchoring device of the present invention is as shown in Fig. 5A.
A mounting part 2 to be attached to the rope C is formed at the center in the longitudinal direction of the base material 1, and a rope C is attached to both sides of the mounting part 2.
A falling-off prevention protrusion 3 is formed on both sides of the falling-off prevention protrusion 3.
A shell-locking protrusion 4 that gradually expands outward toward the side is formed, and knob-holding protrusions 5 of a size to pass through the insertion hole F of the shellfish B are formed at both longitudinal ends of the base material. It is characterized by this.

(Function) To use the aquaculture shellfish anchoring device of the present invention, as shown in FIG. Pass it through the hole F made in the ear E of the scallop B.
Pinch the knob 5 and pull the scallop B to the inside of the shell latching protrusion 4. In this case, scallop B
This causes the shellfish retaining protrusion 4 to fall down, but when the scallop passes by, the protrusion stands up to its original state due to its elasticity and retains the scallop B, preventing it from falling off.

In this case, since the knob 5 is provided, the scallop B can be easily drawn to the inside of the shellfish retaining protrusion 4.

(Example) The aquaculture shellfish retaining device of the present invention will be explained based on the drawings from FIG. 5 onwards.

The aquaculture shellfish locking device of the present invention is molded from plastic, and has a mounting portion 2 that is attached to a rope formed in the center in the longitudinal direction of a base material 1, and a slip-off prevention protrusion that is fixed to a rope C on the outside thereof. 3 is formed, shell locking protrusions 4 are formed on both sides of the pull-out prevention protrusion 3 and gradually expand outward toward the pull-out prevention protrusion 3, and knob protrusions are provided at both longitudinal ends of the base material 1. A child 5 is formed.

The base material 1 has a mounting portion 2 formed into a round rod shape, and both side portions 6 thereof are thin and flat.

The slip-off prevention protrusion 3 is formed into a round bar shape that is slightly thinner than the attachment part 2, and is gradually expanded outward as it faces inward. The structure, shape, etc. of the slip-off prevention protrusion 3 may be other than those shown in the drawings.

The shell-locking protrusions 4 are formed on both sides of the slip-off prevention protrusion 3 so as to gradually expand outward toward the slip-off prevention protrusion 3, and the base portion 7 is made thick.
The tip is made thinner so that the tip side has elasticity in the direction of the arrow.

The knob 5 is used when pulling the scallop B to the inside of the shell holder 4 after inserting the aquaculture shellfish retainer into the hole F in the ear E of the scallop B. This is to prevent the aquaculture shellfish retainer from slipping when pinched. Three knob protrusions 5 are connected to one side of the shellfish locking protrusion 4 at uniform intervals. The knob protrusion 5 is formed into a spherical shape.

The aquaculture shellfish retaining tool shown in FIG. 5 does not have one shellfish retaining protrusion 4 on each side of the mounting part 2, but in some cases two protrusions 4 on the right and left sides of the detachment prevention protrusion 3 may be used. The above structure may be formed.

(Effects of the invention) The aquaculture shellfish anchoring device of the invention has the following various effects.

(b) Since the tabs 5 are formed on both ends of the base material 1 in the longitudinal direction, the scallop B can be inserted into the aquaculture shellfish retaining tool 1 and the inserted scallop B can be attached to the shell retaining protrusions 3. The work of pulling it to the inside becomes much easier.

(b) Since the slip-off prevention protrusion 3 is formed, the aquaculture shellfish anchoring device can be attached to the braided rope C by simply inserting the aquaculture shellfish anchoring device into the knitted rope C from one end to the attachment part 2.
It won't come off. Therefore, the work of attaching the aquaculture shellfish anchoring device to the knitted rope C becomes very easy.

(c) Since the shellfish retaining protrusion 4 is formed, simply insert the aquaculture shellfish retainer into the through hole F drilled in the ear E of the scallop B and pull the scallop B to the inside of the shellfish retaining protrusion 4. The scallop B can be attached to the aquaculture shellfish retaining tool, and the work of attaching the scallop B to the aquaculture shellfish retainer becomes very easy.

(d) If a plurality of shellfish retaining protrusions 4 are formed on one shellfish retaining tool for aquaculture, a plurality of scallops B can be hung on one shellfish retaining tool for aquaculture. A large number of scallops B can be cultivated with a small number of aquaculture shellfish anchoring devices, which is economical.
