Description

Technical Field

[0001] The utility model relates to the technical field of fishing devices, in particular to an adult fish fishing device for a breeding cage. Background Art

[0002] In order to utilize offshore resources to cultivate seafood, such as fish, shrimp, crab, kelp, seaweed, etc., farmers often choose to enclose a certain area in the sea and invest in aquaculture cages of different sizes to limit the movement range of seafood. When the seedlings grow up, the adult fish can be taken out when the nets are collected.

[0003] The aquaculture cages on land are welded to the ground. The general way of fishing is to drain the liquid directly or use a net bag to catch adult fish. This can easily damage the fish body and affect its appearance when sold. After draining, it is necessary to consider environmental pollution and wastewater treatment. The usual fishing methods lack assistance and restrictions. If you use your hands to hold it directly, it will consume physical strength, and the net bag structure will be damaged due to improper force during the fishing process.

[0004] Now, a novel adult fish catching device for aquaculture cages is proposed to solve the above problems. Utility Model Content

If an adult fish is caught, the side rod keeps the two net bags vertically raised and lowered, and the gravity is used for screening and filtering. Then, the large adult fish and the small adult fish are taken out from top to bottom in turn, without the need to distinguish the fish sizes again later. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Specifically, Figure 1 and Figure 2 As shown, the fine mesh bag 7 and other items at the center of the device are directly immersed in the net box, and the longitudinal electric wheels 13 and the transverse electric wheels 10 that form a 90-degree vertical state are in contact with the outer walls on both sides of the net box, and the movable base 5 is in contact with the ground. At this time, the spacing between the fine mesh bags 7 is also pulled apart to a certain distance. The first bolt 3 is used to adjust the spacing between the support rod 2 and the hollow tube 4 according to the height of the net box, so that the flat plate 1 and the salvage mechanism can be moved along the net box, or the pull rod 12 can be held to manually drive the rotating shaft to run. Because the connecting rod 14 is movably inserted between the pull rods 12, the flat plates 1 on both sides can move synchronously.

[0027] Embodiment 2: An active chamber 19 is provided between the top and bottom ends of the vertical plate 6, and a screw rod 9 is inserted in the active chamber 19, a motor 15 is installed at the top end of the vertical plate 6, an internal thread block 18 is sleeved on the outside of the screw rod 9, and a fixing plate 16 is welded to the front end of the internal thread block 18 in a transverse manner, a motor 17 is installed on the outside of the fixing plate 16, and a shaft sleeve 20 is welded to the left side of one side of the side rod 8;

[0028] The other side of the fixed plate 16 is movably mounted in the sleeve 20, the output shaft of the motor 17 passes through the sleeve 20 and is fixedly connected to the side rod 8, the inner wall of the internal thread block 18 is engraved with the pattern of the meshing screw 9, and the internal thread block 18 can slide vertically along the inner wall of the vertical plate 6;

[0029] Specifically, Figure 1 and Figure 3As shown, the motor 15 is turned on and the screw rod 9 is vertically rotated in the movable chamber 19 of the vertical plates 6 on both sides. Since the outer side of the screw rod 9 is connected with the internal thread block 18 with meshing patterns, the internal thread block 18 and the horizontal fixed plate 16 at the front end thereof are lifted and lowered vertically, and the side rod 8 and the fine-mesh net bag 7 connected thereto are also lifted and lowered together. After the motor 17 is turned on, the fishing box cage can be laid down, and the salvage structure composed of the net bag can be moved horizontally, and then the side rod 8 can be flipped over to make it rise upward to prevent the adult fish from jumping out.

[0030] Embodiment 3: A slideway 21 is longitudinally arranged on the upper inner side of the side rod 8, and a clamping plate 22 is movably inserted in the slideway 21, and a coarse mesh bag 24 is transversely fixedly connected between the clamping plates 22. The upper parts of the front and rear parts of the side rod 8 are meshed and connected with second bolts 23, and the second bolts 23 can lock the position of the clamping plate 22, and the clamping plate 22 can slide vertically along the slideway 21;

At this time, the coarse-mesh net bag 24 is located above the fine-mesh net bag 7. If an adult fish is caught, the side rod 8 keeps the two net bags vertically raised and lowered, and the gravity is used for screening and filtering, and then the large adult fish and the small adult fish are taken out from top to bottom in turn.

[0032] Working principle: When the utility model is in use, the clamping plate 22 connected to the coarse-mesh net bag 24 is inserted into the slideway 21 along the slideway 21 above the inner wall of the side rod 8 for fixing. At this time, the coarse-mesh net bag 24 is located above the fine-mesh net bag 7. If an adult fish is caught, the side rod 8 keeps the two net bags vertically lifted and lowered, and the gravity is used for screening and filtering. Then, the large-sized adult fish and the small-sized adult fish are taken out from top to bottom in turn, and then the fine-mesh net bag 7 and other objects at the center of the device are directly immersed in the net box. The longitudinal electric wheel 13 and the transverse electric wheel 10 that form a 90-degree vertical state are attached to the outer walls on both sides of the net box, and the mobile base 5 contacts the ground. At this time, the spacing between the fine-mesh net bags 7 is also pulled apart to a certain distance. The first one is used according to the height of the net box. By adjusting the distance between the support rod 2 and the hollow tube 4 by the bolt 3, the flat plate 1 and the salvage mechanism can be moved along the net cage, or the pull rod 12 can be held to manually drive the rotating shaft to run. Since the connecting rod 14 is movably inserted between the pull rods 12, the flat plates 1 on both sides can be moved synchronously. When catching, the motor 15 is turned on to vertically rotate the screw rod 9 in the movable chamber 19 of the vertical plates 6 on both sides. Since the outer side of the screw rod 9 is connected to the internal thread block 18 with meshing patterns, the internal thread block 18 and the horizontal fixed plate 16 at the front end thereof can be vertically lifted and lowered, and the side rod 8 and the fine-mesh net bag 7 connected thereto can also be lifted and lowered together. After turning on the motor 17, the fishing box cage can be laid down, and the salvage structure composed of the net bag can be moved horizontally, and then the side rod 8 can be flipped over to make it rise upward to prevent the adult fish from jumping out.
