2. Description of the Related Art Conventionally, as a continuous-stage aquaculture cage of this kind, a support frame arranged in a plurality of stages, an enclosure made of a mesh attached to the outside of the support frame of each stage, and the above-mentioned stages. A shelf that is attached to the support frame and consists of nets that form a plurality of storage chambers in the outer enclosure, and a butt-shaped vertical split corresponding to each storage chamber in the body of the outer enclosure. The target inlet / outlet mouth portion and a plurality of hanging ropes connected to the outer periphery of the support frame at a plurality of locations are provided, and the mesh of the mouth portion is sewn with a closing thread made of polyethylene single thread or the like, A configuration is known in which the mouth can be closed. In general, in order to improve strength, improve operability, stability in the sea, and efficiency in taking out shellfish, etc., the support frame is formed in a circular shape and the whole is formed in a cylindrical shape. ing.

In order to use this multi-stage aquaculture cage, for example, during aquaculture, a semi-shelled shell is put into the storage chamber through the mouth, and the mesh near the mouth is closed with a thread to close the mouth. In this way, a multi-stage aquaculture cage containing semi-finished shells is submerged in the sea for aquaculture. In addition, when removing shellfish after cultivation for thinning in the next step of intermediate cultivation, for example, when hanging shell culture, transferring to rough cages or removing for shipping after culture, continuous culture is performed. Pull the basket from the sea to the ship or land. Then, the closing thread is removed to open the mouth, the multi-stage aquaculture cage is turned sideways, and the two ends of the suspension rope are held by two workers in total, and the multi-stage aquaculture cage is shaken vertically. , Open the mouth by the weight of the shellfish and drop it. If it is difficult to drop the shellfish from the mouth even if you shake the multi-stage aquaculture cage at once as described above, by shaking it up and down individually for each storage room on each stage,
Open the mouth of the shellfish by its own weight and drop it.

[0004]

[Problems to be Solved by the Invention] By the way, shellfish and the like are raised from the state of being cultured in the sea along with the cage to the onboard or onshore, transferred to a separately prepared cage, and then put into the ocean again. The work cannot be said to be in a good environment for shellfish and the like, and it is necessary to perform the above-mentioned series of work in a short time as much as possible. However, the mouth portion of the above-described conventional multi-stage aquaculture cage is formed only by butt-shaped vertical cracks, and it is difficult to open it widely, so that growing large and overlapping shellfish are discharged. Not only is it difficult to transfer the shellfish, etc., it may weaken the shellfish and hinder the subsequent growth.
Since it is necessary to grab the support frame and the net in the vicinity of the storage cage for each storage chamber and shake it strongly up and down,
At this time, there is a possibility that the net cloth forming the body portion may be damaged.

The present invention solves the above-mentioned conventional problems, and makes it possible to greatly widen the input / output section and to easily and quickly input / discharge the aquaculture target. Therefore, the working efficiency of aquaculture can be improved, and it is possible to prevent the subsequent growth of shellfish and the like from being adversely affected, and further, to prevent damage to the outer circumference and improve durability. It is an object of the present invention to provide a multi-stage aquaculture cage that can be made to grow.

[0006]

In order to solve the above-mentioned problems, the present invention provides a support frame arranged in a plurality of stages, an outer enclosure made of a mesh attached to the outside of the support frame, and the support frame. And a shelf made of a net-like object that forms a plurality of storage chambers in the outer envelope, and is formed in the body of the outer envelope so as to be opened and closed in a double-ended manner along the axial direction. An input / output section for aquaculture objects that can be opened and closed;
A plurality of suspension ropes connected to a plurality of locations on the outer periphery of the support frame are provided.

In the above construction, both door pieces of the double door opening / closing section can be overlapped and the upper and lower end portions of both door pieces can be closed, and the body portion of the outer envelope can be cylindrical. It is also possible to provide an identifying means for identifying the position of the charging / discharging portion.

According to the present invention configured as described above,
Since the loading / discharging part can be opened wide in a double door type, shells and the like can be loaded easily and quickly into each storage chamber, and the loading / discharging part can also be opened in a double door type when removing shellfish, etc. Since it can be opened widely, it can be easily and quickly dropped by the weight of shellfish and the like and discharged by swaying the whole body laterally and shaking it relatively lightly up and down.

As shown in FIGS. 1 to 4, the support frames 1 are arranged in a plurality of vertical rows at desired intervals.
A plurality of reinforcing bars 3 (two in the illustrated example) are crossed so that the support frame 1 of each step passes through the center of a circular outer frame 2, and the crossing portions are connected by a connecting tool 4 for each reinforcement. Both ends of the crosspiece 3 are bent and connected to the outer frame 2. The connection position is set so as to be substantially evenly divided (per 90 degrees in the illustrated example) on the circumference.

Outside the support frame 1, a net-like object, in the illustrated example, a net cloth made of synthetic fiber, is connected to an outer enclosure 8 having a cylindrical body 5, a circular bottom 6 and a circular ceiling 7. It is installed in. In the body 5, a net-shaped object, a circular shelf 9 made of a synthetic fiber net in the illustrated example, is attached to the supporting frame 1 in a connected state and supported on the supporting frame 1 at each stage in the middle part. There is.

On the body portion 5 of the outer enclosure 8 is formed a double door type loading / unloading unit 11 for loading or unloading aquaculture objects so as to open / close all the storage chambers 10 along the axial direction. ing. In the illustrated example, the body portion 5 of the loading / discharging portion 11 is separated along the axial direction, and both side portions of the separating portion are formed as door pieces 12 and 13, respectively. Are set to be almost full width, or the width from the cutoff portion to the middle portion, that is, a desired width, and the base portions of the door pieces 12 and 13 on the opposite side to the cutoff portion are separated from each other. Is connected to the circular frame 2 by a connecting thread 14. Also, the door pieces 12, 1
The upper end edge and the lower end edge of 3 are overlapped and connected to each other by a connecting thread 15, or integrally connected and fixed to the outer frame 2.

Then, with the door pieces 12 and 13 stacked and closed, the overlapping portion is inserted along the axial direction by a closing thread 16 made of polyethylene single thread or the like so as to sew using a mesh. As a result, the door pieces 12 and 13 are openably closed. By removing the closing thread 16 from the mesh, the door pieces 12 and 13 are opened in a double-door manner with the base portion, that is, the connecting portion with the outer frame 2 as a fulcrum, to open the opening portion 1.

The support frames 1 are bundled substantially on the center line. A weight (not shown) is connected to the lower end of the hanging rope 18 as necessary.

In order to use the continuous culture cage constructed as described above, the closing thread 16 which closes the door pieces 12 and 13 as described above is removed (pulled out), and then, FIGS. 2 and 4 (a). , (B)
As shown in FIG. 2, the door pieces 12 and 13 are opened in a double-door manner to form an opening 17, and the storage chamber 1 of each stage is formed from the opening 17.
Put a half-shelled oyster in 0 and place it on the shelf 9. At this time, since the opening 17 can widely open each storage chamber 10 by opening the door pieces 12 and 13 in a double-door manner, it is possible to easily and quickly perform the work of inserting the half-shells and the like. . When the half-shells are stored in this way, the door piece 12,
13, and the door piece 12 by the closing thread 16 as described above,
13 is closed, a multi-stage aquaculture cage containing semi-shelled shells and the like is submerged in the sea, and the upper end of the hanging rope 18 is connected to a raft (not shown) moored above the sea to support the submerged cage in the submerged state.
The semi-adult shells are cultivated in this state, but since the multi-stage cultivating cage is entirely formed in a cylindrical shape, it is obedient to tidal current and can be stabilized in the sea.

When the shellfish are taken out, the continuous-stage aquaculture cage is lifted from the sea, the continuous-stage aquaculture cage is laid sideways as shown in FIG. 5, and both ends of the hanging rope 18 are held by different operators 19 and thrown in and out. The closing thread 16 that closes the door pieces 12 and 13 of the part 11 is removed, and the loading / discharging part 11 is turned downward and rocked. Along with this, the grown shellfish 20 pushes the door pieces 12 and 13 by its own weight to open in a double-door type (see FIGS. 2, 4 (a), and 4 (b)), and as described above, the storage chambers 10 at each stage are widened. Since it opens, it falls from this opening 17. At this time, since the whole is formed in a cylindrical shape,
The shellfish 20 can be easily dropped to the lower opening 17 side, and the shellfish 20 can be easily and quickly discharged by gently rocking the continuous culture cage in the vertical direction.

Next, a second embodiment of the present invention will be described. FIG. 6 is a schematic perspective view of a part of a continuous culture cage according to the second embodiment of the present invention.

As shown in FIG. 6, the feature of this embodiment is that, as an example of means for identifying the position of the loading / discharging portion 11, of the door pieces 12 and 13, a door piece overlapping the outer surface. The color of the net thread 21 forming the part 13 is different from the color of the net thread forming the main body of the outer envelope 8. For example, the outer circumference 8
When a blue net yarn is used for the main body of the above, a green net yarn is used for the door piece 13. As another example of the identification means, the hanging rope 18 at the position sandwiching the input / output port 11 is set to black and the other hanging ropes 18 are set to blue. Input like this
By applying the identification means of the discharge part 11,
Input / discharge section 11 even if a large amount of marine organisms such as mussels, barnacles, polydoras, and starfish adhere to cover the outer enclosure 8 etc.
Can be easily found, and the work of discharging shellfish and the like can be performed quickly.

In the above embodiment, the outer envelope 8,
Although the Russell net is used for the door pieces 12, 13, etc., frog or knot net can also be used. Also, the door pieces 12, 13
However, they may be abutted and closed by a closing thread without overlapping. Further, although the upper and lower ends of the door pieces 12 and 13 are connected, they may not be connected. In addition, the present invention can be modified in various ways without departing from the basic technical idea thereof.

[0020]

As described above, according to the present invention, since the charging / discharging portion can be largely opened in a double door type, shellfish or the like can be charged into each storage chamber easily and quickly. Since the loading / discharging part can be opened wide in a double-door manner even when removing shellfish, etc., by gently rocking the whole body sideways up and down, you can easily and quickly drop by the weight of the shellfish etc. Can be made. Therefore, it is possible to improve the working efficiency of aquaculture, and to prevent the subsequent growth of shellfish and the like from being adversely affected. Moreover, it is possible to prevent damage to the outer circumference and improve durability. it can.

Further, by stacking both door pieces of the double door type opening / closing section, when closing with the closing thread, it suffices to pass roughly through the mesh, so that the work efficiency can be further improved.

Further, by forming the whole into a circular shape, it is possible to improve the strength, the operability, the stability in the sea, and the efficiency of discharging shellfish and the like.

Further, by providing a means for identifying the input / output section, the input / output section can be easily found even if a large number of marine organisms adhere to cover the outer circumference and the like. The discharging operation can be performed even more quickly, and the subsequent growth of shellfish and the like can be prevented from being adversely affected.
