The present invention relates to an automatic jellyfish dispensing device, and more particularly, when the jellyfish is caught in the jellyfish removal net installed in front of the bag net in the fishing operation using the bag net, the end of the jellyfish removal net Jellyfish outlet is automatically opened when the elastic body attached to the connecting string connecting the bottom plate of the sack net is automatically closed and the jellyfish outlet is automatically closed by the elastic body that is retracted after the jellyfish is discharged. It relates to a jellyfish automatic discharge device characterized in that.

In general, when fishing with a single- or twin-hook fishing net using low-tethered fishing nets in the offshore, jellyfish are trapped inside the low-tethered net, which hinders fishing. Jellyfish, which are damaging to various fishing as mentioned above, are known as large bush jellyfish (scientific name: Nomura mouth), and the body size is usually 120cm or more in diameter and the weight of jellyfish is about 30kg. Because of the size of the jellyfish of this size, the resistance of the sea is very much underwater. And because the average net speed is 3.5 knots even when the low net is on board, these net speeds result in tremendous resistance due to the nature of the jellyfish's body when it reaches the fishing gear. May interfere with the operation of fishing vessels and may threaten distress.

      In recent years, various techniques have been developed using jellyfish outlets to remove jellyfish that interfere with fishing operations. Are not using these devices because they are not economical. In other words, in order to separate and discharge the jellyfish introduced into the net to the outside of the net, a jellyfish can be discharged into the bag-shaped fishing gear, but through this outlet, many fish are drawn out of the net so that the catch loss is too high. It happens.

      Therefore, since the above problems occur, a lot of devices for removing jellyfish flowing into the bag-shaped net have been developed. Looking at the patent applications among these technologies, as shown in FIGS. 1 and 2, the Republic of Korea registration In the Utility Model Publication No. 20-330470 (registered on Oct. 7, 2003), the jellyfish removal net 500 formed of the netting 501 larger than the netting 301 of the net 300 is inclined inside the fishing net 100. To form a discharge hole 300A and the jellyfish removal net 500 portion of the discharge hole 300A portion is extended to form a discharge guide net 500A to form a jellyfish 600 introduced into the fishing net 100 There is a known technique for a jellyfish removal device of a low-network to allow the fish net 100 to be discharged to the outside, but in the case of the jellyfish removal device, the jellyfish discharge port is too small for the size of the jellyfish. In addition, there is a risk that the discharge efficiency will be lowered due to the market, and also that the jellyfish outlet is always open, causing fish to escape through the outlet, causing problems in fishing.

  And the Republic of Korea Patent Publication No. 10-2005-53576 (published on June 8, 2005) as shown in Figure 3 inside the bag net 100 inclined downward toward the rear side jellyfish guide net 210 and the rear side Jellyfish discharge net 260 is inclined upward is fixed to the bag-shaped net 100 at regular intervals, the lower end of the jellyfish induction network 210 is not fixed to the bag-type net 100 jellyfish inlet ( 220 is formed, the jellyfish discharge net 260 is connected to the rear side of the jellyfish discharge port 270 formed by cutting the top of the bag-shaped net 100, the rear side of the jellyfish guide net 210 The first and second fish guide passages 230 and 240 which are net passages are connected and extended to branch to both sides along the inner space of the bag net 100, and the rear end thereof is connected to the jellyfish discharge network 260. Of the bag net (100) connected to the cover net (280) Jellyfish separation and discharge device is characterized in that it is installed to form a fish outlet 250 between the side plate, the jellyfish is discharged through the jellyfish induction network, jellyfish discharge network, jellyfish outlet and cover net Since the structure of the jellyfish separating and discharging device is complicated, there is a fear that the separating and discharging efficiency of the jellyfish is low, and the manufacturing work is complicated.

Therefore, the present inventors have completed the present invention by developing a simple device having a high effect of discharging jellyfish by using the principle that the jellyfish outlet is automatically opened and closed by using the resistance received from the seawater by the jellyfish caught in the net.

The present invention was devised as a solution for solving the above problems, the jellyfish automatic discharge device of the present invention is installed in the bag net inclined downward in the direction of the end of the jellyfish removal network, the jellyfish was caught in the jellyfish removal network Only when the jellyfish outlet is automatically opened by the elastic body as the jellyfish's bottom plate and the rear of the jellyfish outlet frame with the jellyfish elimination net are pushed toward the stool by the resistance that the jellyfish receives from the seawater. It is an object of the present invention to provide an automatic jellyfish discharge device, characterized in that the loss of catches can be reduced as much as the jellyfish discharge port is automatically closed by the contracting elastic body.

Therefore, the jellyfish automatic discharge device of the present invention is not only easy to manufacture because of its simple structure, but also can easily maintain its function by simply replacing the elastic body in the care of the net.

      And the jellyfish automatic discharge device of the present invention is not only a function for discharging the jellyfish introduced into the bag-shaped net to the outside of the mesh, but also to be cut by the connecting string connected to the elastomer when the jellyfish exits the discharge port with a jellyfish relief function It is possible to reduce the resistance of the seawater to the net by blocking jellyfish and fish from being caught, so it is possible to reduce the fuel economy of the fishing boat, overload of the engine, and to inhibit the merchandise of the fish which can be caused by the toxicity of the jellyfish. Another object of the present invention is to provide an automatic jellyfish discharge device, which is characterized in that it can solve various problems such as causing skin diseases.
