Description

Technical Field

[0001] The utility model relates to the technical field of fry separation, in particular to an efficient fry separation structure. Background Art

[0002] Freshwater fish breeding ponds are used to breed fry of different species. When breeders want to observe the growth of fry or judge whether the fry are sick, they basically fish them out outside the pond.

[0003] The existing Chinese patent with the publication number CN203942959U discloses a multi-layer fish fry separation fishing net, including a support rod. A first-layer fishing net is fixed on the support rod. A second-layer fishing net is fixed below the first-layer fishing net. The upper end of the second-layer fishing net is fixed on the support rod. The mesh aperture of the first-layer fishing net is larger than that of the second-layer fishing net. By using the first-layer fishing net and the second-layer fishing net with different mesh apertures and fishing out fry outside the pond, the utility model can preliminarily separate fish of different sizes, save a lot of time and improve the fishing efficiency.

[0004] However, when the fry separation structure is removed from the water, it will be subjected to a large acting force. There is no buffer force structure. When it is subjected to a large acting force for a long time, it is easy to cause the holding rod to bend or even be damaged, and the service life is low. Content of the Utility Model

[0005] In view of the above problems in the prior art, the utility model provides an efficient fry separation structure, which solves the problem that the holding rod of the existing fry separation structure cannot buffer the acting force and is easy to be damaged.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] Provide an efficient fry separation structure, including a holding rod. One end of the holding rod is provided with a buffer structure connected to a fry separation tank. The buffer structure includes a mounting plate. A connecting column is fixed in the middle of one side of the mounting plate. The connecting column is fixedly connected with the holding rod. Two first connecting plates are oppositely fixed on the other side of the mounting plate. An elastic component is arranged between the two first connecting plates and is connected to the fry separation tank through the elastic component.

[0008] In this solution, when holding the holding rod and extending the fry separation tank into the breeding pond to fish out fry, when the fry separation tank is removed from the water to the outside, it will be subjected to a large acting force. The elastic component in the buffer structure can buffer this acting force, thus avoiding the situation that the acting force on the fry separation during fry separation suddenly changes sharply, resulting in the holding rod bending or being damaged, and improving the service life of the holding rod.

[0009] Furthermore, a plurality of water-permeable holes are evenly formed in all the wall plates of the fry separation tank.

[0010] In this scheme, multiple water-permeable holes are used to facilitate the separation of fry from water during salvage.

[0011] Furthermore, the connecting column is screwed into the first threaded hole on the end of the gripping rod and is threadedly connected to the gripping rod.

[0012] In this solution, threaded connection is adopted, which is easy to disassemble and assemble, reduces the occupied volume, and is convenient to carry.

[0013] Furthermore, a carrying handle is fixed to the middle of the grip rod.

[0014] In the present invention, a lifting handle is adopted for the user to grasp, so that the fry separation tank can be easily moved out of the water for use.

[0015] Furthermore, the other end of the handle is covered with an anti-slip cover.

[0016] In this solution, the anti-slip cover can prevent the user from slipping when holding the handle.

[0017] Furthermore, the elastic component includes two limit columns, a telescopic hydraulic rod and a second connecting plate; the two limit columns and the two ends of the telescopic hydraulic rod are respectively fixed on the two first connecting plates, and the telescopic hydraulic rod is located between the two limit columns; the second connecting plate is movably arranged on the middle part of the two limit columns and the telescopic hydraulic rod, and is fixedly connected to the fry separation trough.

[0018] In this solution, the telescopic hydraulic rod contracts when subjected to force and can automatically reset, thereby driving the second connecting plate to move and buffering the force of the fry separation tank.

[0019] Furthermore, two second through holes and a third through hole are provided on the second connecting plate, the second through hole is clearance-matched with the limiting column, and the third through hole is interference-fitted with the telescopic hydraulic rod; a spring is sleeved on the limiting column between the first connecting plate and the second connecting plate.

[0020] In this solution, when the fry separation tank is subjected to force, the second connecting plate moves on the two limit columns and drives the telescopic hydraulic rod to retract. The elastic force of the spring and the thrust of the telescopic hydraulic rod can buffer the force and prevent sudden changes in the force on the grip rod.

[0021] Furthermore, two limiting columns are symmetrically distributed on both sides of the telescopic hydraulic rod, and two ends of the limiting columns respectively pass through the first through holes on the two first connecting plates and are threadedly connected to the limiting plates.

[0022] In this solution, threaded connection is used to facilitate fixing and disassembly.

[0023] The utility model discloses a high-efficiency fry separation structure, which has the following beneficial effects:

[0024] 1. The utility model utilizes the elastic component in the buffer structure to buffer the force exerted when the fry separation tank is moved out of the water to the outside, avoiding the force on the grip rod from undergoing a sharp mutation, preventing the grip rod from being bent or damaged, and improving the service life of the grip rod.

[0025] 2. The utility model utilizes the setting of the carrying handle. When the weight inside the fry separation tank is heavy, the user can hold the grip rod with one hand and the carrying handle with the other hand to move the fry separation tank out of the water, facilitating the user to move the heavy fry separation tank out of the water and making it convenient for the user to use, with strong practicability.

However, it should be clear that the present utility model is not limited to the scope of the specific embodiments. For those of ordinary skill in the art of this technical field, as long as various changes are within the spirit and scope of the present utility model defined and determined by the appended claims, these changes are obvious, and all utility models created using the concept of the present utility model are within the scope of protection.

[0032] Embodiment 1

[0033] Referring to Figure 1 , this embodiment provides an efficient fry separation structure, the purpose of which is to solve the problem that the grip rod of the existing fry separation structure cannot buffer the force and is easily damaged. The following will show its composition in detail.

[0034] An efficient fry separation structure of this embodiment includes a holding rod 3, a fry separation tank 12, and a buffer structure.

[0035] The holding rod 3 is used to provide force for the user to drive the fry separation tank 12. An anti-slip sleeve 1 is sleeved on one end of the holding rod 3, and a lifting handle 2 is fixed on the holding rod 3 and located at the end of the anti-slip sleeve 1. The user can hold the anti-slip sleeve 1 of the holding rod 3 with one hand and hold the lifting handle 2 with the other hand to move the fry separation tank 12 out of the water, which facilitates the user to move the relatively heavy fry separation tank 12 out of the water and makes it easier to apply force.

[0036] The other end of the holding rod 3 is provided with a buffer structure for connecting with the fry separation tank 12.

[0037] The upper part of the fry separation tank 12 is open, and a plurality of water permeable holes 11 are uniformly arranged on all the wall plates. The plurality of water permeable holes 11 facilitate the separation of fry from water during fishing.

[0038] In this embodiment, when the user holds the holding rod 3 and inserts the fry separation tank 12 into the breeding pond to fish for fry, when the fry separation tank 12 is moved out of the water to the outside, it will receive a large acting force. The elastic component in the buffer structure can buffer this acting force, thus avoiding the situation that the acting force on the fry separation tank 12 during fry separation suddenly changes sharply, resulting in the bending or damage of the holding rod 3, and improving the service life of the holding rod 3.

[0039] As a further solution of this embodiment, refer to Figure 2 , the buffer structure includes a mounting plate 4, two limit posts 5, two first connecting plates 7, a connecting column 14, and an elastic component.

[0040] The connecting column 14 is fixed in the middle of one side of the mounting plate 4, and the free end of the connecting column 14 is screwed into the first threaded hole 13 at the end of the holding rod 3 to be threadedly connected with the holding rod 3. The threaded connection is convenient for disassembly and assembly, reduces the occupied volume, and is convenient for carrying.

[0041] Two first connecting plates 7 are oppositely fixed on the other side of the mounting plate 4. An elastic component is arranged between the two first connecting plates 7 and is connected with the fry separation tank 12 through the elastic component.

[0042] The elastic component includes two limit posts 5, a telescopic hydraulic rod 8, and a second connecting plate 10;

[0043] The two ends of the two limit posts 5 and the telescopic hydraulic rod 8 are respectively fixed on the two first connecting plates 7, and the telescopic hydraulic rod 8 is located between the two limit posts 5.

[0044] In this embodiment, the telescopic hydraulic rod 8 is of the model HOLO-62-140-318-003. When the telescopic hydraulic rod 8 is stressed, it contracts and can automatically reset. It can drive the second connecting plate 10 to move and buffer the acting force of the fry separation tank 12.

[0045] Reference Figure 3 and Figure 4 Two limiting columns 5 are symmetrically distributed on both sides of the telescopic hydraulic rod 8. External threads 18 are provided at both ends of the two limiting columns 5. The two ends of the limiting columns 5 respectively pass through the first through holes 16 on the two first connecting plates 7 and are threadedly connected to the second threaded holes 15 of the limiting plate 6.

[0046] The second connecting plate 10 is movably arranged on the middle parts of the two limiting columns 5 and the telescopic hydraulic rod 8 and is fixedly connected to the fry separation tank 12.

[0047] Specifically, two second through holes 17 and a third through hole are provided on the second connecting plate 10. The second through holes 17 are in clearance fit with the limiting columns 5, and the third through hole is in interference fit with the telescopic hydraulic rod 8. Springs 9 are sleeved on the limiting columns 5 between the first connecting plate 7 and the second connecting plate 10.

[0048] In this embodiment, when the fry separation tank 12 is stressed, the second connecting plate 10 moves on the two limiting columns 5 and drives the telescopic hydraulic rod 8 to retract. The elastic force of the springs 9 and the thrust of the telescopic hydraulic rod 8 can both buffer the stress and prevent the force on the holding rod 3 from changing suddenly.

[0049] The working principle of this embodiment is as follows:

[0050] When the user holds the holding rod 3 and inserts the fry separation tank 12 into the breeding pond to salvage fry, the user can hold the anti-slip sleeve 1 of the holding rod 3 with one hand and hold the lifting handle 2 with the other hand to move the fry separation tank 12 out of the water. When the fry separation tank 12 is moved out of the water to the outside, it will receive a large acting force. The fry separation tank 12 drives the second connecting plate 10 to move on the two limiting columns 5 and drives the telescopic hydraulic rod 8 to retract. The elastic force of the springs 9 and the thrust of the telescopic hydraulic rod 8 can both buffer the stress and prevent the acting force on the holding rod 3 from changing suddenly, avoiding the situation of the holding rod 3 being bent or damaged and improving the service life of the holding rod 3.

[0051] Although the specific implementation manners of the utility model have been described in detail with reference to the drawings, it should not be construed as a limitation on the protection scope of this patent. Within the scope described in the claims, various modifications and deformations that can be made by those skilled in the art without creative labor still fall within the protection scope of this patent.
