Seedlings are introduced and scientifically fed to achieve the large-scale growth of crayfish and finally harvest them.

[0003] During the harvesting process, bait is placed inside the pond to attract crayfish. Then, the net can be placed along the pond bank or in the crayfish ditch. The net is retrieved the next day, the harvested crayfish are poured out, and the adult crayfish that meet the required size are selected.

[0004] However, in crayfish fishing operations, traditional net cages generally adopt a fixed structure for the shrimp inlet channel design, which makes it easy for crayfish to get stuck inside the cage, making it difficult to unload quickly. Manual unloading of the cage is also required, which is cumbersome and the overall unloading time is long. Therefore, the inventor has proposed an improved fishing device. Utility Model Content

[0036] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0037] This utility model embodiment specifically provides a catching device for lobster farming. Please refer to... Figures 1-6 , including subject 1.

[0038] The main body 1 includes an inlet cylinder 2 and a net cylinder 3 that are detachably connected. Lobsters enter the net cylinder 3 through the inlet cylinder 2. The outer side of the net cylinder 3 is fixedly connected to the opening and closing ring 4. After the catching is completed, the net cylinder 3 and the opening and closing ring 4 can be opened in half to facilitate the quick discharge of the lobsters inside.

[0039] Specifically, the top of the mesh tube 3 is provided with an opening parallel to its axis. The openings are magnetically attached to each other by magnetic strips 31. Magnetic strips 31 are commonly used components, often found on door curtains. The mesh tube 3 has an overall cylindrical structure and is made of commonly used nylon mesh, which is wear-resistant and corrosion-resistant. When the magnetic strips 31 on both sides of the opening are set, one side can be the N pole and the corresponding position on the other side can be the S pole. In this way, when the openings are connected, the opposite magnetic poles are exactly opposite, which allows the openings to close stably.

[0040] Furthermore, since the opening is located at the top of the net tube 3, and the load-bearing force is located below the net tube 3 when loading lobsters, and the outer side of the net tube 3 is fixedly connected to the opening and closing ring 4, the outer side of the net tube 3 is fixed to the opening and closing ring 3 over a large area. Therefore, when the net tube 3 is loaded with lobsters, it will apply a pulling force to the area fixedly connected to the net tube 3. At the same time, due to the elasticity and toughness of its own material, it will not pull on the opening, so that the opening can always be closed by the magnetic strip 31.

[0041] Among them, there are two or more opening and closing rings 4 arranged along the axial direction of the net cylinder 3, and the net cylinder 3 is detachably connected to the inlet cylinder 2 through the opening and closing rings 4. Since there is no limitation on the length of the net cylinder 3, the number of opening and closing rings 4 is adapted to the length of the net cylinder 3. The lobster inlet end of the net cylinder 3 is detachably connected to the inlet cylinder 2, so that the lobster can enter the interior of the net cylinder 3 through the inlet cylinder 2.

[0042] During implementation, lobster bait can be placed inside the net tube 3 to lure the lobsters into the net tube 3.

[0043] Furthermore, both ends of the net cylinder 3 are fixedly connected to the opening and closing rings 4, that is, an opening and closing ring 4 is fixedly installed at both the left and right ends of the net cylinder 3, and a closed net 5 is installed inside the opening and closing rings 4 at both ends. The closed net 5 creates a closed space for lobster catching inside the net cylinder 3. One of the closed nets 5 is detachably connected to the inlet cylinder 2 to facilitate the overall opening of the net cylinder 3.

[0044] It is worth noting that, in order to facilitate the opening and closing of the opening and closing ring 4, the overall structure of the closed net 5 is set as two symmetrical fan-shaped mesh structures. When the opening and closing ring 4 is opened, the closed nets 5 distributed on the left and right can open to each other. At the same time, the material of the closed net 5 is metal, and the symmetrical spacing between the left and right is smaller than the size of the finished lobster, so as to prevent the finished lobster from crawling out of the gap when the closed net 5 is closed.

[0045] The opening and closing ring 4 includes two symmetrically arranged ring bodies 41, the bottom ends of the two ring bodies 41 are rotatably connected, and the top ends of the two ring bodies 41 are detachably connected by a disassembly mechanism.

[0046] During implementation, the bottom ends of the ring 41 are connected to each other by hinge 44. When the top end of the ring 41 is separated by the disassembly mechanism, its bottom ends can be rotated away from each other and opened. The outer sides of the net cylinder 3 and the closed net 5 are fixedly connected to the inner side of the ring 41, so that the net cylinder 3 can form a tubular net structure through the fixed support of the ring 41.

[0047] The ring body 41 is fixedly provided with a first counterweight 45 at the bottom. When the net cylinder 3 is put into the water, the first counterweight 45 can make the bottom of the ring body 41 stably placed on the bottom of the water, so that it will not easily tip over. It can also make the opening stably located above the net cylinder 3.

[0048] By adopting the above technical solution, after the lobsters are caught, they accumulate at the bottom of the net tube 3. By opening the net tube 3 and the opening and closing ring 4, the entire net tube can be opened in half. Then, the net tube 3 and the opening and closing ring 4 can be poured out directly to dump the lobsters. If any lobsters remain, they can be quickly removed by hand. The operation is simple and quick.

[0049] Furthermore, the disassembly mechanism includes a first fixing structure 42 and a second fixing structure 43 respectively disposed on the ring body 41. The first fixing structure 42 and the second fixing structure 43 are detachably connected, and the two ring bodies 41 are respectively connected to a fixing structure, so as to facilitate the connection and separation of the two ring bodies 41 through the two fixing structures.

[0050] In one possible implementation of the first fixing structure 42 and the second fixing structure 43, the first fixing structure 42 is a long strip fixedly installed on one of the rings 41. The long strip has a slot 421 and a separation groove 422. The material of the long strip is the same as that of the ring 41, which can both be hard metal. It is connected to the second fixing structure 43 through the slot 421 and the separation groove 422.

[0051] Specifically, the second fixing structure 43 includes a plug 431 that is inserted into the slot 421 on the outside. A slide rod 432 is fixedly installed at the bottom of the plug 431. The plug 431 and the slide 432 are coaxially fixed. The bottom of the slide rod 432 is inserted into the ring 41 that is not equipped with the first fixing structure 42. The insertion of the slide rod 432 into the ring 41 prevents the two rings 41 from separating after being subjected to rotational force, thus keeping them in a single unit.

[0052] In practice, the outer end of the separation groove 422 is an open structure, the separation groove 422 penetrates the upper and lower surfaces of the ring body 41, the depth of the slot 421 is two-thirds of the depth of the separation groove 422, the outer diameter of the slide rod 432 is smaller than the inner diameter of the slot 421, and the outer diameter of the slide rod 432 is smaller than the width of the separation groove 422, so that the separation groove 422 will not come into contact with the slide rod 432.

[0053] In this embodiment, since the insert post 431 and the slide rod 432 are respectively inserted into the slot 421 and the ring 41, the two rings 41 will not rotate relative to each other after being restricted, so that the two rings 41 can remain closed and will not cause the mesh tube 3 to open. When it is necessary to open the mesh tube 3, it is only necessary to apply force to the insert post 431 to separate it from the slot 421, so that the slide rod 432 can move upward, causing the ring 41 to drive the separation groove 422 on the strip to pass through the slide rod 432 and open outward, thereby realizing the separation of the two rings 41.

[0054] The top of the insertion post 431 is fixedly equipped with a second counterweight 434 to increase the insertion weight of the insertion post 431. Under the influence of gravity, in normal conditions, it is difficult for the ring body 41 to move the insertion post 431 vertically upward without human power. At the same time, since the ring body 41 applies a lateral pulling force to the insertion post 431 in normal conditions that is coaxial with its circumference, the vertical upward lifting force on the insertion post 431 is small, so as to ensure the insertion stability with the slot 421 in normal conditions.

[0055] As another possible implementation of the second fixing structure 43, a cavity 411 is provided at the insertion point of the ring 41 and the slide rod 432. The cavity 411 is a cylindrical structure. The outer side of the slide rod 432 slides in conjunction with the solid area above the cavity 411. A limiting plate 433 is fixedly installed at the bottom end of the slide rod 432 to limit the upward movement of the slide rod 432 and prevent it from falling and being lost accidentally.

[0056] It is worth noting that the first counterweight 45 and the second counterweight 434 are both made of solid metal. The weight can be set according to the actual size of the device during implementation, which will not be described in detail here.

[0057] Furthermore, an assembly component 6 is provided on the opening and closing ring 4 near the inlet cylinder 2. The opening and closing ring 4 is detachably connected to the inlet cylinder 2 through the assembly component 6. Since the mesh cylinder 3 and the opening and closing ring 4 need to be opened and closed, while the inlet cylinder 2 does not, the assembly component 6 can meet the needs of quick loading and unloading connection between the inlet cylinder 2 and the opening and closing ring 4 that needs to be opened and closed, thereby improving the convenience of use.

[0058] As one possible implementation of the assembly component 6, the assembly component 6 is arranged in a four-position array within the ring body 41. The assembly component 6 includes a mounting bracket 61 and a support 62 with one end fixedly connected to the mounting bracket 61. The other end of the support 62 is fixedly connected to the ring body 41. The mounting bracket 61 has an arc-shaped structure. When the opening and closing ring 4 is closed, the four mounting brackets 61 form a ring-shaped partition structure. At the same time, if the opening and closing ring 4 is opened, the partition structure disappears to facilitate the subsequent detachable connection of the inlet cylinder 2.

[0059] Furthermore, the inlet tube 2 includes a funnel-shaped mesh 21 and an inlet ring 22 and an inlet ring 23 respectively fixedly installed at both ends of the funnel-shaped mesh 21. Due to the structure of the funnel-shaped mesh 21 being larger on the outside and smaller on the inside, after the lobster enters the inside of the net tube 3 along the funnel-shaped mesh 21, it is affected by the height and has difficulty climbing out from inside the inlet ring 22.

[0060] Meanwhile, the side of the inlet ring 22 away from the closing ring 4 is attached to the bracket 61 that forms a partition structure, so that the inlet ring 22 can be supported by the bracket 61 to prevent it from falling off. At the same time, after the bracket 61 is removed, the two can be quickly separated, which makes it convenient for the net cylinder 3 and the opening and closing ring 4 to be opened or closed, and improves the cleaning efficiency after the lobster is caught.

[0061] It is worth noting that a circular opening is formed in the middle of the closed mesh 5 near the inlet cylinder 2 for the speaker mesh 21 to pass through. Normally, the circular opening is in contact with the outer side of the speaker mesh 21.

[0062] Among them, the leftmost ring 41 and the inlet ring 23 are both fixedly installed with rope rings 7 for fixing ropes. The ropes are inserted into the main body 1 through the rope rings 7 in a vertical downward movement path, which facilitates the salvage operation.

[0063] Those skilled in the art should understand that this utility model is an improved device. Its innovation lies in the collaborative layout and specific structural relationship of the components, rather than the way the basic functions are implemented. The connection between the existing parts, the operating parameters and control logic are all common knowledge and conventional design choices in the field. Technical personnel can determine the appropriate specific implementation method by conducting limited experiments or referring to technical manuals according to the overall design requirements of the equipment, or by having a qualified professional manufacturer standardize and guide the operation according to mature industry standards. No creative labor is required.

[0064] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, which will not be described in detail here.
