Description

Technical Field

[0001] This utility model relates to the technical field of adult fish catching devices, specifically a screenable adult bass catching device. Background Technology

[0002] Sea bass, also known as spotted sea bass or seven-star sea bass, belongs to the order Perciformes and family Perciformes in taxonomy. Because it breeds and grows in coastal areas, unlike freshwater bass such as California bass and mandarin sea bass, it is also called sea bass. When sea bass are farmed and caught, fishing nets or other fishing devices are used to catch the grown sea bass.

[0003] However, existing bass catching devices use a unified fishing net to catch all bass in one go. Different sizes and immature bass are mixed in the net. After being caught, a second sorting process is required, either manually or by machine, to separate immature bass and bass of different sizes. However, this method is extremely labor-intensive and cannot automatically sort bass of different sizes at the time of capture, which increases the complexity of subsequent processing.

[0004] Therefore, in view of this, we have studied and improved the existing structure to propose a screening device for catching adult bass. Utility Model Content

[0005] The purpose of this invention is to provide a screenable adult bass catching device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a screenable adult bass catching device, comprising a main box, a secondary box below the main box, a bottom box below the secondary box, and openings evenly distributed on the upper surfaces of the main box and the secondary box.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4 As shown, a screenable adult bass catching device includes a main box 1, a secondary box 2 below the main box 1, a bottom box 3 below the secondary box 2, and openings 4 evenly distributed on the upper surfaces of the main box 1 and the secondary box 2. The openings 4 on the surface of the secondary box 2 are smaller than the openings 4 on the main box 1. An escape prevention mechanism 5 is provided on the inner surface of each opening 4. Assembly mechanisms 6 are provided on the lower end of the main box 1 and the secondary box 2 and on the left and right sides of their outer surfaces. The secondary box 2 has various types of openings 4 with different sizes.

[0023] By adopting the above technical solution, the main box 1, the auxiliary box 2 and the bottom box 3 form a complete capture device;

[0024] The bottom box 3 can be filled with fish attractant to guide the bass above to swim downwards;

[0025] The sea bass from outside will first enter the main tank 1 through the passage 4, and then enter the secondary tank 2 through the passage 4;

[0026] The diameter of the through opening 4 on the sub-tank 2 is reduced, that is, the large-sized sea bass cannot enter the sub-tank 2, only the small-sized sea bass can enter, thereby screening the sea bass of different sizes when being captured.

[0027] Further, the anti-escape mechanism 5 comprises a groove 501 formed on the left and right inner surfaces of the through opening 4, the inner surface of the groove 501 is rotationally installed with a movable plate 502, the lower surface of the movable plate 502 is fixedly installed with a flexible spring 503, and the lower end of the flexible spring 503 is fixedly connected with the inner surface of the groove 501.

[0028] Through the above technical scheme, when the sea bass passes through the through opening 4 from top to bottom, the movable plate 502 is pushed to rotate downward to press the flexible spring 503, thereby opening the through opening 4, so that the sea bass can swim downstream smoothly, and after the sea bass enters, the flexible spring 503 pushes the movable plate 502 to re-close the through opening 4 in a downward slope;

[0029] When the lower sea bass wants to return to the upper layer or the upper sea bass wants to swim out of the capture device, the upward swimming sea bass will push the movable plate 502 to rotate upward, and the movable plate 502 can only rotate to a horizontal state at the lower edge of the upper edge of the groove 501, thereby completely blocking the through opening 4, so that the sea bass cannot escape from the capture device, and the captured sea bass or the already downstream classified sea bass cannot escape or be mixed again.

[0030] Further, the assembly mechanism 6 comprises a slot 601 formed on the left and right lower surfaces of the main tank 1 and the sub-tank 2, and the outer surfaces of the left and right lower surfaces of the main tank 1 and the sub-tank 2 are fixedly installed with a tension spring 602; the assembly mechanism 6 further comprises a plug 603 fixedly installed at the opposite end of the tension spring 602, the opposite end of the plug 603 is slidably penetrated into the slot 601 of the main tank 1 and the sub-tank 2, and the lower surface of the end of the plug 603 located in the slot 601 is provided as an inclined surface; the upper surfaces of the left and right sides of the sub-tank 2 and the bottom tank 3 are fixedly installed with a plug plate 7, and the surface of the plug plate 7 is provided with a positioning hole 8.

[0031] Through the above technical scheme, the plug plate 7 is inserted into the slot 601, and the plug plate 7 pushes the plug 603 to pull the tension spring 602 outward, when the plug plate 7 is completely inserted, the plug 603 is aligned with the positioning hole 8, and under the action of the tension spring 602, the plug plate 7 is inserted into the positioning hole 8, thereby being fixed, and the assembly of the main tank 1, the sub-tank 2 and the bottom tank 3 is completed, and the plug 603 is pulled out of the positioning hole 8 to be disassembled, so that the main tank 1, the sub-tank 2 and the bottom tank 3 can be quickly disassembled and assembled.

[0032] According to the capture requirement, the sub-tank 2 with the large through opening 4 can be quickly installed into the sub-tank 2 with the small through opening 4, and then sequentially installed downward step by step, thereby completing the multi-stage screening.

[0033] Further, the middle part of the upper surface of the sub-tank 2 is clamped with a barrier net 9, and the mesh number of the barrier net 9 is 150.

[0034] By adopting the above technical scheme, the barrier net 9 can block the lowermost sea bass, so as to avoid the sea bass eating the bait;

[0035] And the barrier net 9 can also avoid the water flow generated by the swimming of the sea bass, so as to roll the bait into the sub-tank 2 or the main tank 1.

[0036] Working principle: when the sea bass is captured by using the sea bass capture device, first, the bait is stored in the bottom tank 3, the plug-in plate 7 is inserted into the plug-in slot 601, the plug-in plate 7 pushes the plug-in pin 603 to pull the tension spring 602 outward, when the plug-in plate 7 is completely inserted, the plug-in pin 603 is aligned with the positioning hole 8, and under the action of the tension spring 602, the plug-in plate 7 is inserted into the positioning hole 8, so as to fix the plug-in plate 7. The above-mentioned way is used to install the sub-tank 2 and the main tank 1, according to the demand, a plurality of sub-tanks 2 with different sizes of through holes 4 can be installed step by step, the bottom tank 3 is installed with the lowermost sub-tank 2, the barrier net 9 forms the bottom plate of the lowermost sub-tank 2, so as to avoid the sea bass contacting the bait, after the installation is completed, a complete capture device is formed, the sea bass is attracted by the smell of the bait, and the sea bass enters the capture device through the through hole 4 of the main tank 1. Since the bait is located at the lowermost position, the entering sea bass will continue to swim downward, but as the through hole 4 of the sub-tank 2 becomes smaller, only the sea bass with small size can enter the sub-tank 2 again, so that the sea bass with different sizes can be screened and captured, and the sea bass with different sizes can be located in different tank bodies of the capture device. When the sea bass passes through the through hole 4 from top to bottom, the movable plate 502 is pushed downward to extrude the flexible spring 503, so as to open the through hole 4, and the sea bass can swim downward smoothly. After the sea bass enters, the flexible spring 503 pushes the movable plate 502 again to block the through hole 4 in a downward inclined manner. However, when the lower sea bass wants to return to the upper layer or the upper sea bass wants to swim out of the capture device, the upward swimming sea bass will push the movable plate 502 to rotate upward, and the movable plate 502 can only rotate to the horizontal state under the lower edge of the upper edge of the groove 501, so as to completely block the through hole 4, so that the sea bass cannot escape from the capture device, and the captured sea bass or the sea bass that has been classified and screened can not escape or re-swim mixed. After the capture is completed, the capture device is taken out and placed upside down, the plug-in pin 603 is pulled out of the positioning hole 8, and the disassembly can be performed. At this time, the bottom of each tank body forms an opening, and the sea bass in the tank body can be taken out. This is the working principle of the sea bass capture device.
