JPH0818168B2 - Jig for piercing the ears of cultured shellfish - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a jig for piercing an ear used for piercing an ear of a cultured shellfish.

[Conventional technology]

Aquaculture of shellfish, for example, scallop cultivation, is carried out by attaching a large number of scallop juveniles to a rope that hangs in seawater. A means for attaching juveniles to the rope via this thread is generally practiced. Conventionally, a means for attaching a thread to a rope by perforating the ear portion of a juvenile, threading the thread through the hole, and a device for carrying out this were not always efficient, The applicant and the inventor have invented a method and a device for efficiently attaching a plurality of juveniles to a rope through a thread, and as a method and a device for hanging scallop aquaculture on November 11, 1986 (Japanese Patent Application No. 61- 266548).

This invention holds a plurality of scallop juveniles and aquaculture ropes at predetermined positions by a jig, perforates juveniles with a drill along the same axis as the ears and the rope, and inserts a thread into this hole of the drill. It is a method and device that inserts the juveniles on the rope at the same time as pulling it out.

The jig used here needs to accurately and efficiently hold the juveniles in a predetermined position, but a jig suitable for this purpose has not been implemented so far. Conventional jigs are of the type that holds a horizontally placed piece of shellfish from above and below, as shown in, for example, Shokai Sho 13-13666, and it is not possible to carry out fine position adjustment of shellfish while holding it down. The position could not be adjusted. It was also impossible to hold a plurality of shells and ropes in place at the same time.

[Problems to be solved by the invention]

As described above, a jig that holds a plurality of shells and ropes used in the patent application relating to the inventions of the applicant and the inventor and the application in a predetermined position and is capable of finely adjusting the position of shells has been conventionally implemented. Was not done. On the other hand, the above-mentioned holder for shellfish that has been conventionally proposed cannot hold a single shellfish in a horizontal state from above and below and therefore cannot be used as a jig of the above patent application.

It is an object of the present invention to solve these problems and to provide a jig for piercing the ears of aquaculture shellfish that is used to pierce a plurality of shell ears and ropes at the same time and to insert a thread. It is a thing.

[Means for solving problems]

Means of the present invention for solving the above problems include a jig pedestal in which a linear shallow groove is formed, and two holding plates which are parallel to each other across the groove and which are vertically attached to the pedestal. A jig for ear piercing of cultured shellfish, characterized in that brush-shaped bristles are planted in an inclined manner on at least one inner surface of the restraining plate to hold the cultured shellfish between the two restraining plates. , And
In addition, a jig pedestal in which a plurality of linear shallow grooves are formed in parallel, and a plurality of pairs of restraining plates mounted in parallel with each other across the plurality of grooves and perpendicular to the pedestal are provided. For piercing the ears of cultured shellfish, brush-shaped bristles are slantly planted inside at least one of the pair of holding plates to hold the cultured shellfish between each pair of the holding plates. A jig.

[Action]

By inserting a shell along a shallow groove between two (a pair of) restraining plates, the shell can be easily held and perforated in the ear. Also, a plurality of shells can be held together with the aquaculture rope at the same time and drilled together with the rope, and by lifting the shells upward, the shells and rope can be easily removed from the jig.

〔Example〕

Next, the present invention will be described by way of examples with reference to the drawings. 1 (A), (B), and (C) show an embodiment of the present invention, (A) is a perspective view, (B) and (C) are top views for explaining the mounting condition of shellfish. is there. In these figures, the jig 1 of the present invention has a flat jig base 2 on which a linear shallow groove 3 is formed. Pedestal 2 across the groove 3
Suppressors 4 and 5 are mounted perpendicular to and parallel to each other.
A large number of bristles 6 are planted on the inner surface of the one restraining plate 4 to form a brush shape. The bristles 6 are inclined with respect to the restraining plate 4, and the inclination angle α is determined by the characteristics of the bristles, the shape of the shell to be supported, etc., but is generally preferably about 30 ° to 45 °.

In order to hold the shell H by the jig 1 for piercing the ear, the ear Ha is placed in the groove 3 from one of the pedestals 2 (right in the figure), and the shell H is inserted between the restraining plates 4 and 5 by an arrow. Feed it in the direction indicated by S. At this time, the shellfish H is fed such that the angle β between the center line C parallel to the feeding direction S of the shellfish H and the hair 6 is an acute angle. Hold the shellfish H in place and pierce the ear Ha with the drill D, and then pass the thread.

2 (A), (B), (C), and (D) show a second embodiment of the present invention, in which (A) is a top view, (B) is a perspective view, and (C) is a side view. The figure and (D) are front views. In these figures, in this embodiment, bristles 6, 6 that are inclined and face each other are planted in the pressing plates 4 and 5, and a stopper 2a is attached to one end of the groove 3 of the pedestal 2. It

The bristles 6 are linear or strip-shaped elastic bodies, and are made of a synthetic resin (nylon or the like) or a stainless steel spring having high fatigue strength against repeated bending and high seawater corrosion resistance.

FIGS. 3 (A) and 3 (B) show an arrangement in which a plurality of shellfish and ropes are perforated at once, (A) is a perspective view, and (B) is a top view. In this case, the pedestal 2 of the jig 1 is provided with two parallel grooves 3a and 3b that end with the same length from the same end, and a groove 3c that ends midway from the opposite end and is parallel to the grooves 3a and 3b and has an axial line offset. Suppressing plates 4a, 5a, 4b, 5b that are formed and sandwich the respective grooves 3a, 3b, 3c.
And 4c and 5c are mounted parallel to each other. Hair 6 is planted in each of the restraining plates 4a, 4b, 4c. Shellfish H ₁ , H ₂ , H ₃
Are held by the respective restraining plates 4a, 5a, 4b, 5b and 4c, 5c, and the rope L is arranged between the restraining plates 5a and 5b and through the outside of 5c, and a drill and a thread are provided along the center line P. A threading tool (not shown) moves to pierce shellfish H ₁ , H ₂ , H ₃ and rope L, and threading is performed in this hole 7 (FIG. 3A). Four or more pairs of grooves and restraining plates may be arranged.

Removing the shellfish H ₁ , H ₂ and H ₃ is extremely easy by pulling the shellfish up.

FIG. 4 shows a means for continuously carrying out perforation of the ears of the shellfish and attachment to the threading rope using the present invention. In this figure, a plurality of jigs 1 are intermittently moved on a belt conveyor 10 in the direction of an arrow M, which are mounted at intervals. A rope L is arranged on each of the jigs 1 at the top as described with reference to FIGS. 3 (A) and 3 (B), and a shell H is inserted by the operator 11. The jig 1 in which the shellfish H has been inserted is temporarily stopped at the position of the piercing threading device 12, and the shellfish H and the rope L are pierced and threaded, and the moved shelled shellfish H and rope L are removed from the jig 1. Removed and moved to the designated place.

〔The invention's effect〕

As described above, according to the present invention, a linear groove is formed on the jig base plate, two parallel restraining plates are installed with the groove sandwiched therebetween, and at least one of the restraining plates has a large number of brush-like shapes. By implanting the bristles, it is possible to provide a jig capable of accurately and easily constructing an ear part perforation of a shellfish such as a scallop. Further, it is possible to provide a jig for piercing an ear, which is capable of quickly and efficiently threading a plurality of shellfish and a culture rope at the same time.
