Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention mainly relates to an aquaculture cage used for aquaculture of shellfish.

[Prior Art] Conventionally, there are various types of cages for shellfish cultivation in the sea, lakes and marshes, but typical cage species are pyramid cages called so-called Zabuton cages, and corrugated cages. There is a bellows type basket called as, the former is a single pyramid type basket, a polygonal frame is sewn on the bottom of the net and a plurality of hanging ropes that penetrate vertically in the center of the basket are used. The baskets are used by connecting them in multiple stages, and one of the four ridgelines is used as an opening for putting in and out shellfish.

Further, the latter is a so-called multi-stage bellows-type aquaculture cage is formed by simultaneously sewing a partition net on the inner peripheral edge of a polygonal frame body and a body net having the same width as the outer peripheral length of the frame body on the outer peripheral edge. The gap between the both edges of the net serves as an opening for the shellfish to enter and exit.

The cages of both types have different shapes, but they have the same opening for loading and unloading shells, and the mouth cord is used to prevent the shells from leaking every time shells are loaded and unloaded. Suturing and withdrawal is required and essential.

In addition, when the stitches by the mouth straps at the opening have a rough pitch, the shellfish stored in the basket can be held by holding the basket sideways and loosening the nets that make up the basket during hanging work, and the shell opens. The shellfish will leak out of the basket.

Also, when the shellfish are taken out, the shellfish grows and the shell length increases, so even if the opening in the sutured state is pushed laterally laterally, the opening is small and Since it is impossible to take out the mouth strap, it is necessary to completely remove the mouth strap. Therefore, when accommodating shellfish in the basket again, it is necessary to sew the mouth strap again at a fine pitch. Therefore, these operations require a great deal of labor.

[Means for Solving the Problems] The aquaculture cage according to the present invention has been made in view of the above-mentioned current state of shellfish aquaculture work, and a shellfish aquaculture cage having the following structure is provided. The purpose is.

The aquaculture cage of the present invention comprises a net of synthetic fiber material and a rectangular bottom frame, and comprises a plurality of box-shaped cages formed by sewing a binding thread along the upper edge of the side net. , Each at any depth in the upper opening, that is, until the bottom frame is fitted to the position below the binding yarn of the bottom basket alone, and then the binding yarn is tightly bound, the upper part of the side net is Since the upper baskets that are fitted together are fastened at a position above the bottom frame of the upper baskets, the plurality of baskets are vertically bellows-shaped and integrated, After fitting a mesh lid of the same shape in the opening in the same manner, hold the four hanging ropes and attach the bottom cages of the lower cages that are in close contact with each other at predetermined positions near the diagonal corners of the bottom cages that are engaged with each other. Multi-stage aquaculture with a structure in which the binding thread sewn on the upper edge of the side net is grasped and continuously bound together at an arbitrary interval. It is.

Therefore, in and out of the shellfish in the aquaculture cage according to the present invention,
Of the two diagonals of each corrugated basket, one of the diagonals having a large V-shaped opening, that is, one of the two openings can be used, and can be easily made by loosening the binding thread.

[Operation] Since the present invention is a multi-stage aquaculture cage having the above structure, it is possible to adjust the number of stages, that is, to select the cage length according to the shallow depth of the water area where the aquaculture facility is installed. When carrying it sideways, the large V-shaped openings at two diagonal corners of each corrugated cage tighten and tighten the binding threads, respectively, so that the upper side edge of the side net of the lower corrugated cage is in the upper corrugated cage. Since it will come into close contact with and be inserted into and removed from the lower part of the side net of the body, it will be possible to open and close it easily and reliably, which will improve the efficiency of shellfish loading and unloading work and the side net of the cage Even if it becomes a loose state, it will bring about an effect that the leakage of the shellfish contained in the cage of each stage can be prevented.

[Embodiment] An embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 3, a quadrangular bottom frame body 3 having rigidity and excellent corrosion resistance is sewn and fixed on the bottom net 1b of the net body 1 having four side nets 1a and one bottom net 1b. In addition, the bottom portion d of another basket simple substance a can be arbitrarily placed in the upper opening c of the plurality of box-like basket simple substances a formed by sewing the binding thread 5 along the upper edge of the side net 1a. When the binding yarns 5 of the lower basket unit a are tightly bound after being fitted in order to the depth, as shown in FIG. 4, at the position above the bottom portion d of the fitted upper basket unit a, that is, the bottom frame body 3,
The upper part of the lower basket unit a is fastened, and a plurality of basket units a
Is to be integrated in the vertical direction in a bellows shape. Further, after fitting the net lid single body b having the same shape as the bottom frame 3 into the opening c of the uppermost basket a1, as shown in FIG. As shown in Fig. 4, with the four hanging ropes 6, the bottom frame 3 to which the cages a1 ...
The predetermined positions 3b ... 3b near the diagonal corners 3a ... 3a of the three ... It is a multi-stage aquaculture cage A having a structure in which it is bound together at intervals.

Since the aquaculture cage A according to the present invention has the above-mentioned structure, the shellfish accommodating work is performed by first loosening the binding thread 5 of each corrugated cage a1 ... a1 as shown in FIG. Side network 1a ... 1a
The upper cage a1 whose upper end is fitted in the opening c1 ... c1
... a1 bottom part d1 ... d1 that is, the bottom frame bodies 3 ... 3 large V-shaped openings c1 ... c1 having diagonal corners 3a ... 3a, that is, one or two openings c1 can be used. ,continue,
Since the opening c1 is sealed by tightly binding the binding yarns 5 of each of the corrugated cages a1 ... a1, the shellfish in the cage A will not leak out even during lateral carrying.

When the shellfish stored in the basket A is to be taken out as needed, by loosening the binding thread 5 of the side nets 1a ... 1a of each corrugated cage a1 ... A large V-shaped opening is formed by inserting and removing the upper portions of the side nets 1a ... 1a that are fastened to 3a.
c1 ... c1, 1 or 2 places will spread out diagonally downward as shown in FIG. 2, and if one of the diagonals 3a ... 3a is directed downward with the basket A lying down, The shellfish stored in the cage A are smoothly discharged to the outside of the cage A because the weight of the shellfish and the side nets 1a of the two surfaces forming the diagonals 3a ... 3a are inclined at 45 degrees.

[Advantage of the Invention] Since the aquaculture cage according to the present invention has the above-described structure, it can reliably and rationally perform the shellfish loading / unloading operation and the lateral carrying operation, and is adapted to the shallow water depth of the aquaculture area. The height of the basket can be adjusted and the effect can be easily achieved.
