The present invention relates to a jellyfish separation and cutting device for separating the jellyfish that are caught with the fish in various operations using the bag net, more specifically, the jellyfish guide net in the front end of the bag net And jellyfish screening network, respectively, to form the flow passage of fish itself, forming a jellyfish inlet at the upper side of the jellyfish guide network, and at the bottom of the bag-shaped net which is directly below the jellyfish screening network. By forming a jellyfish outlet with a cover of the form, it is possible to effectively separate the jellyfish that are caught with the fish from the fish, and to minimize the amount of fish discharged with the jellyfish, and to separate the fish and the jellyfish. While simplifying the structure, the jellyfish's discharge passage is directed towards the bottom of the bag net. In addition, it is possible to achieve time and cost reduction and maximize the jellyfish discharge performance according to the production of fishing gear, thereby minimizing the fishery damage caused by the jellyfish's congestion and maximizing operating efficiency to improve the management balance according to the fishery. The present invention relates to a jellyfish separation and cutting device that can contribute to the income increase of the fisherman and at the same time, to ensure that jellyfish are cut to a certain size when the jellyfish are separated and discharged.

In general, an operation method using a bag net such as a trawl fishing or a low net fishing is as shown in FIG. 1, and the bag net 10 having the back plate 11, the bottom plate and the side plate 12 integrally formed therein is various. The fish net is formed using both mantles, and then the bag net 10 released in this way is retracted to the fish group using the vessel 1, whereby the fish group enters the inside of the bag net 10. It is to be trapped in the end of the rear end (13).

However, in recent years, jellyfish have appeared in coastal waters in large quantities in summer due to changes in the marine environment, causing enormous damage to fisheries. In addition to fishing methods such as trolls, low nets, Ahngang nets, Kwon Hyun nets, Nang Jang nets, and Yeong nets, almost all types of fisheries, including the fishing nets, the fishing nets, and the nets of the fishing nets, appear in a wide variety of forms. In the operation mode, jellyfish are very easily caught with fish, causing a lot of damage.

In other words, when jellyfish are mixed with fish into the bag net 10 during the operation using the bag net 10, the resistance of the fishing gear in the process of enveloping the bag net 10 by the vessel 1 is caused. This greatly increases the variety of fishing gear including the bag net 10, or a large amount of jellyfish block the net of the end 13, that is, the hole of the net to inhibit seawater circulation to reduce the catch, or jellyfish Many problems such as the death of fish caused by the entrapment of the fish and the damage of the fish body by the jellyfish resulted in deterioration of the commerciality.

In addition, there was a problem in that the fishing environment was further worsened because it takes a considerable time and cost to separate the catch and jellyfish from the catch by the manpower from the catch caught by the bag net (10). Not only did the worker's skin be exposed to the poison of the jellyfish during the separation, but it also caused secondary problems such as damage to the human body. There have also been frequent cases of giving up.

In order to solve the various problems caused by the jellyfish in the process of operation using the bag net 10 as described above, the jellyfish separate discharge device 20 in front of the end 13 of the bag net (10) By installing it, it is possible to effectively separate the jellyfish that are caught with the fish and at the same time minimize the amount of fish discharged with the jellyfish, thereby reducing the fishery damage caused by the jellyfish caught and maximizing the operating efficiency. Patent application No. 40786 (Application Date: May 16, 2005) and Patent Registration (Registration No. 518361, Registration Date: September 23, 2005) are known by the applicant.

First, after wrapping the bag-shaped net (10) provided with the jellyfish separation and cutting device 30 according to the present invention on both vessels of the vessel (1) to determine the position of the fish group to be captured using various fish finders, etc. After decommissioning the bag-shaped net 10, the jellyfish separation and cutting device 30 is installed according to the present invention using a machine, the bag-shaped net 10 released in this way to the fish group side using the vessel (1) do.

As described above, in the process of envisaging the bag net 10 provided with the jellyfish separation and cutting device 30 according to the present invention to the fish group, when the number of jellyfish is large, such as summer, a large amount of jellyfish together with the fish Into the inside of the net (10), the jellyfish that are caught with the fish as described above is completely separated from the fish through the jellyfish separation and cutting device 30 according to the present invention and then to the outside of the bag net (10) Only the fish cut off and separated from the jellyfish are collected through the end 13 of the bag net 10.

That is, the jellyfish introduced into the bag net (10) with the fish is jellyfish separation and cutting device according to the present invention by the preliminary force of the bag net 10, as shown by the dotted arrow in FIG. Move to the upper side along the jellyfish induction network 31 of (30), and then through the jellyfish inlet 32 to the bottom surface side of the bag-shaped net 10 formed with the jellyfish outlet 34 along the jellyfish barrier network 33. Will move.

The jellyfish moved to the bottom surface side of the bag-shaped net 10, the jellyfish outlet 34 is formed as described above passes through the outlet cover 35 of the foot shape installed in the jellyfish outlet 34, the interior of the jellyfish collection network 36 The jellyfish gathered into the jellyfish collecting network 36 is integrated into the rear end side of the jellyfish collecting network 36 by the pretension of the bag net 10, and at the cutting ejector 38. It is discharged to the outside of the bag-shaped net 10 in a cut state to a certain size.

At the same time, since the fish introduced into the bag-shaped net 10 together with the jellyfish has a mesh of sufficient size for the passage of the fish, the jellyfish induction network 31 and the jellyfish blocking network 33 have a solid arrow in FIG. 5. As shown, the main inflow of fish is directed to the end 13 of the bag net 10 via the jellyfish guide net 31 and the jellyfish barrier net 33.

In addition, as described above, the small number of fish that can be discharged together with the jellyfish through the jellyfish outlet 34 has a preliminary force of the bag-shaped outlet cover 35 after the jellyfish passes. Due to the natural drought by, avoid the foot-shaped outlet cover 35 in accordance with the obstacle avoidance instinct of the fish, and then guided to the end 13 of the bag net 10 through the jellyfish barrier net 33 Will be.

As described above, when the jellyfish separation and cutting device 30 according to the present invention is installed and used in the bag type net 10, the jellyfish mixed with the fish is effectively separated from the fish to the outside of the bag type net 10. At the same time, the amount of fish discharged with the jellyfish through the jellyfish outlet 34 can be minimized, and the jellyfish can be cut to a certain size when the jellyfish is discharged, thereby achieving the jellyfish relief function. It becomes possible.

Therefore, in various operations using the bag net 10, damage to the various phrases including the bag net 10 is minimized by minimizing the resistance of the phrase caused by the jellyfish being mixed with the fish into the bag net 10. It is possible to prevent or breakage, a large amount of jellyfish block the mesh of the end 13, that is, the net hole to reduce the catch due to the seawater distribution, the death of fish caused by the jellyfish's congestion and the fish caused by jellyfish It is possible to minimize problems such as deterioration of the merchandise due to damage.

In addition, since the jellyfish are automatically separated and discharged in the process of estimating the bag net 10, it is possible to prevent the waste of time and money caused by separating the jellyfish from the catches by manpower one by one, so that the treatment of the catches can be performed more efficiently. As a result, it is possible to reduce the fishery damage caused by the jellyfish's congestion and maximize the fishing efficiency, thereby greatly improving the income balance of the fisherman.

In addition, since the jellyfish separation and cutting device 30 according to the present invention can be selectively installed and used immediately before the end 13 of the bag-shaped net 10, as in the case of the filing application, jellyfish is generated in large quantities. When the jellyfish separation and cutting device 30 according to the present invention is installed in the bag-shaped net (10) and used so that the jellyfish can be removed at the time, continuous operation is possible regardless of the appearance of the jellyfish. Since all the materials constituting the jellyfish separation and cutting device 30 are made of flexible net, it is possible for fishers to perform their use and maintenance more conveniently than when using a solid body.

In particular, the jellyfish separation and cutting device 30 according to the present invention is such that the jellyfish induction network 31 and the jellyfish blocking network 33 itself to form a flow passage of the fish, such as the jellyfish separation and discharge device 20 of the prior application The jellyfish separation and cutting device is not provided on both sides of the mold net 10 so that a separate net passage such as the first and second fish guide passages 23 and 24, which serve as a movement and discharge passage of the fish, is not provided. It is possible to further simplify the overall structure of the bag-shaped net 10 including the 30, thereby reducing the time and costs associated with the manufacture of the bag-shaped net 10 including the jellyfish separation and cutting device 30 Can be saved.

In addition, while the discharge path of the jellyfish separated from the fish is directed toward the bottom side of the bag-shaped net 10, the jellyfish introduced through the jellyfish inlet 32 is located on the lower side of the jellyfish blocking net 33 Because of this, the jellyfish is rapidly guided along the jellyfish barrier net 33 to the bottom side of the bag net 10 by the horizontal component and the weight of the jellyfish, which make up the greatest force in the case of the bag net 10. In addition, the jellyfish floating in the upper side in this process can also be easily guided to the bottom side of the bag-shaped net 10 by the jellyfish blocking net 33.

Therefore, the jellyfish quickly guided to the bottom side of the bag net 10 can be easily pushed toward the jellyfish collection network 36 through the jellyfish outlet 34, and thus the interior of the jellyfish collection network 36 Jellyfish that were pushed out were also rapidly accumulated on the rear end side of the jellyfish collecting network 36 by the horizontal component forming the pretension of the bag-shaped net 10, and then quickly and easily cut and discharged by the cutting ejector 38. As a result, it is possible to further improve the separation and cutting discharge function of the jellyfish than the previously filed jellyfish separation and discharge device 20.

As described above, the jellyfish separation and cutting device according to the present invention has an effect of automatically separating the jellyfish, which are mixed with the fish in the various operation processes using the bag-shaped net, with the fish to be discharged to the outside of the bag-type net. In addition, the amount of fish discharged along with the jellyfish through the jellyfish discharge port is minimized, and the jellyfish can be cut to a certain size when the jellyfish is discharged, thereby achieving the relief function of the jellyfish.

Therefore, in various operations using the bag net, the resistance of the fishing gear caused by the jellyfish being mixed with the fish inside the bag net can be minimized to prevent damage or damage to various gear including the bag net. It is possible to reduce the amount of catches caused by the large number of jellyfish blocking the netting of the end, that is, the net hole, and to inhibit the distribution of the seawater, and the deterioration of the merchandise due to the death of fish due to the jellyfish's congestion and the damage of the fish body by jellyfish. There is an effect that can minimize the problem.

In addition, since jellyfish are automatically separated and discharged in the process of forecasting the bag net, it is possible to prevent the waste of time and money caused by separating the jellyfish from the catch by manpower and thus to efficiently process the catch. As a result, it is possible to reduce the fishery damage caused by the jellyfish's congestion and to maximize the fishing efficiency, thereby greatly improving the income balance of the fisherman.

In addition, since the jellyfish separation and cutting device according to the present invention can be selectively installed and used immediately before the end of the bag-shaped net, the jellyfish separation and cutting device according to the present invention when the large amount of jellyfish occurs By installing and using it on the net, it is possible to dismantle it when there is no jellyfish, so it is possible to continuously operate regardless of whether jellyfish is infested.So, all the materials that make up the jellyfish separation and cutting device are made of flexible net. There is an effect that makes it easier for fishermen to perform their use and maintenance than when using a.

In particular, the jellyfish separation and cutting device according to the present invention is such that the jellyfish induction network and jellyfish blocking network itself to form a flow passage of the fish, such as the jellyfish separation and discharge device of the pre-applied fish movement and discharge passage on both sides of the bag-shaped net Since a separate net passage such as the first and second fish guide passage is to be installed, there is an effect to simplify the overall structure of the bag net including the jellyfish separation and cutting device, Due to this, there is an effect to save time and money according to the manufacture of the bag net including a jellyfish separation and cutting device and to contribute more to the income increase of the fisherman.

In addition, the jellyfish introduced through the jellyfish inlet is located at the lower side of the jellyfish barrier network, with the discharge path of the jellyfish separated from the fish facing the bottom side of the bag-shaped net. Jellyfish are not only rapidly guided along the jellyfish barrier net to the bottom of the bag net by the horizontal force and the weight of the jellyfish that make up the greatest force, but also the jellyfish that floats to the upper side in the process. Since it is easily guided to the bottom side of the bag-shaped net, it is effective to cut and discharge jellyfish quickly and easily through the jellyfish outlet, jellyfish collection network and cutting ejector, thereby separating and Effective to improve cutting and ejection function A.
