[0002] In the process of artificial hatching of fish, especially the hatching of sticky eggs, it is generally necessary to go through the steps of artificial egg squeezing, fertilization, debonding, hatching, etc. In the process of hatching fish eggs in the hatching bucket, some fish eggs sometimes cause a large number of dead eggs in the early hatching stage due to insufficient maturity, or the fish egg membrane is fragile and thin, with poor elasticity and is very easy to break due to improper debonding operation or over-mature fish eggs, which will lead to the early appearance of a large number of dead eggs, egg membranes and foams such as mucus produced by egg membrane lytic enzymes in the hatching water. When the existing fish egg hatching device is used to hatch sticky eggs, during the oxygen supply process, since the aeration head is located below the hatching bucket, after the aeration head is aerated, dirt such as egg membranes and foams will move upward with the bubble flow, and the dirt will further spread to all parts of the hatching bucket, affecting the cleanliness of the water body in the hatching bucket, which is not conducive to the smooth hatching of fish eggs.

[0024] The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0025] An incubation device for hatching fish adhesive eggs, as Figures 1 to 3As shown in the figure, it includes an incubation barrel 1, an overflow pipe 2 arranged above the incubation barrel 1, and a drain pipe 3 arranged below the incubation barrel 1. At least three overflow pipes 2 are evenly arranged around the incubation barrel 1, and a filtering mechanism is provided on the barrel body at the position corresponding to the overflow pipe 2. Specifically, the overflow pipe 2 and the drain pipe 3 can be fixed on the incubation barrel 1. In addition, a water inlet pipe 5 can also be arranged at the position above the overflow pipe 2 on the incubation barrel 1, and the water inlet pipe 5 can also be fixed on the incubation barrel 1.

[0026] During actual use, control valves 4, such as stop valves, can be arranged on both the drain pipe 3 and the water inlet pipe 5 to realize the control of the on-off of the pipeline. Those skilled in the art can also select appropriate valves for installation according to actual needs. Installing valves on the pipeline belongs to the prior art, so it will not be elaborated here.

[0027] The above-mentioned filtering mechanism includes a frame body 6, an oxygen pipe 7 arranged in the middle of the frame body 6, and a limiting rod 8 arranged around the frame body 6 corresponding to the overflow pipe 2. One end of the limiting rod 8 is arranged on the frame body 6, and the other end is provided with a filtering box 9 that can cooperate with the overflow pipe 2. A concave part 12 that cooperates with the overflow pipe 2 is arranged below the filtering box 9, and a receiving groove 16 for receiving a filtering element 10 is arranged above the filtering box 9. A water passing hole 13 for communicating the receiving groove 16 and the overflow pipe 2 is arranged on the filtering box 9 at the position corresponding to the concave part 12; one end of the oxygen pipe 7 is arranged on the frame body 6, and the other end is provided with an aeration head 19. An adsorption net 11 is arranged on the oxygen pipe 7 at the position between the frame body 6 and the aeration head 19, and at least two adsorption nets 11 are arranged at intervals along the length direction of the oxygen pipe 7.

[0028] Exemplarily, both the oxygen pipe 7 and the limiting rod 8 can be fixed on the frame body 6, while the filtering box 9 can be fixed on the limiting rod 8. Among them, three, four or more overflow pipes 2 can be arranged along the circumferential direction of the incubation barrel 1. Here, three are taken as an example, and correspondingly three limiting rods 8 are also arranged.

[0029] By arranging three overflow pipes 2 and arranging filtering boxes 9 that can cooperate with the overflow pipes 2 on the three limiting rods 8, three-point limiting of the frame body 6 can be realized, so that the frame body 6 can be stably installed on the incubation barrel 1. Those skilled in the art can also set multiple overflow pipes 2 according to actual needs, which will not be elaborated here.

[0030] During actual application, the aeration head 19 can be installed on the oxygen pipe 7. The aeration head 19 can adopt existing aeration stones or bubble stones and be installed and fixed on the oxygen pipe 7 by corresponding installation methods. Those skilled in the art can also select other appropriate aeration heads 19 and corresponding installation methods according to actual needs to realize aeration and oxygenation of the water body in the incubation barrel 1, which will not be elaborated here.

[0031] By arranging at least two adsorption nets 11 at the position on the oxygen pipe 7 corresponding to the position between the frame body 6 and the aeration head 19, after the aeration head 19 aerates, the bubble flow will drive the dirt to flow upward. At this time, the two adsorption nets 11 can play a good role in intercepting and adsorbing the dirt, effectively removing the dirt in the water body. Then, as the bubble flow continues to float upward, a fountain will be formed in the middle of the hatching barrel 1. Under the action of the fountain, suspended dirt such as foam will move towards the edge of the hatching barrel 1, and after being adsorbed and filtered by the filter element 10 in the filter box 9, it will be discharged through the overflow pipe 2, so that the suspension amount of dirt in the hatching barrel 1 can be effectively reduced, which is beneficial to improving the cleanliness of the water body in the hatching barrel 1.

[0032] Optionally, the limiting rod 8 can also adopt an existing telescopic rod. The fixed end of the telescopic rod is fixed on the frame body 6, and the telescopic end is fixed on the filter box 9. By adopting the telescopic rod, the operator can adjust the length of the limiting rod 8 according to the diameter of the hatching barrel 1, so that the filter box 9 on the limiting rod 8 can cooperate with the overflow pipe 2, and further enables the filtering mechanism to better adapt to hatching barrels 1 with different diameters, which is beneficial to improving the applicability and versatility of the filtering mechanism.

[0033] Optionally, a net frame 20 for arranging the adsorption net 11 is provided on the oxygen pipe 7. The net frame 20 is of a dome-shaped structure, and there is a water passing gap between the periphery of the net frame 20 and the inner wall of the hatching barrel 1. Exemplarily, the net frame 20 is fixed on the oxygen pipe 7. Two, four or more adsorption nets 11 can be arranged at intervals. The net frame 20 and the adsorption net 11 are arranged in one-to-one correspondence. The adsorption net 11 can adopt a polyethylene fishing net with a mesh aperture of 3 - 6 mm. Hooks or hook rings for installing the adsorption net 11 can be fixed on the net frame 20. Those skilled in the art can also select a suitable adsorption net 11 and corresponding installation methods according to actual needs to realize the assembly of the adsorption net 11 on the net frame 20, which will not be elaborated here.

[0034] By arranging a plurality of adsorption nets 11, the adsorption nets 11 can form a dome-shaped structure under the limiting action of the net frame 20. The plurality of adsorption nets 11 can more effectively adsorb the egg membranes and mucus in the water body. As the bubble flow drives the water body to flow, the fish eggs can pass through the aperture of the adsorption net 11 and hang in the water body for natural hatching, and the circulating water body has more sufficient oxygen, which is also beneficial to further improving the hatching success rate of the fish eggs.

[0035] In the actual application process, by adopting the grid 20 with a dome-shaped structure, a depression for converging dirt can be formed on the side of the grid 20 facing the aeration head 19, which is beneficial for the adsorption net 11 to better collect the dirt flowing with the bubble flow and prevent the collected dirt from detaching from the adsorption net 11. After the water body forms a fountain through the adsorption net 11, the water body can return to the lower part of the hatching barrel 1 along the water passing gap between the grid 20 and the hatching barrel 1, and then oxygenation is carried out again, forming a circulating oxygenation of the water body, which is beneficial to increasing the oxygen content of the water body and ensuring the smooth hatching of fish eggs.

[0036] Optionally, an adsorption filter cotton 17 is provided at the edge of the grid 20, and the adsorption filter cotton 17 is an annular structural member. Exemplarily, the adsorption filter cotton 17 is a synthetic fiber filter cotton with a mesh aperture of 1-2 mm. An assembly groove for limiting the adsorption filter cotton 17 is provided on the grid 20, and the adsorption filter cotton 17 can be snap-fitted with the assembly groove, so as to realize the convenient assembly of the adsorption filter cotton 17 on the grid 20. In addition, those skilled in the art can also install the adsorption filter cotton 17 on the grid 20 in other ways, such as installing and fixing it on the grid 20 by screws. Threaded holes communicating with the assembly groove are provided at the positions corresponding to the assembly groove on the grid 20. Those skilled in the art can select a suitable method by themselves, which will not be elaborated here.

[0037] By arranging the annular adsorption filter cotton 17 at the edge of the grid 20, the adsorption filter cotton 17 can play a further adsorption and filtration role on the dirt intercepted in the adsorption net 11, prevent the dirt from overflowing from the edge of the adsorption net 11, which is beneficial to further improving the adsorption and filtration effect of the filtering mechanism on the dirt and improving the cleanliness of the water body.

[0038] Optionally, at least three counterweight members 18 are evenly arranged around the grid 20. Exemplarily, the counterweight members 18 can be evenly arranged in three, four or more numbers. The counterweight members 18 can be heavy objects such as stones, and the counterweight members 18 can be installed and fixed on the grid 20 by tying ropes. By arranging a plurality of counterweight members 18 around the grid 20 and using the counterweight members 18 to counterweight the grid 20, it is beneficial to improve the stability of the grid 20 and the adsorption net 11, prevent the grid 20 and the adsorption net 11 from floating up with the bubble flow, and ensure that the adsorption net 11 can continuously and stably adsorb and filter the dirt in the water body.

[0039] Optionally, a detachable limiting plate 14 is provided at a position corresponding to the recessed portion 12 below the filter box 9. A fitting gap for cooperating with the overflow pipe 2 is formed between the limiting plate 14 and the recessed portion 12. Exemplarily, the filter element 10 can be an adsorption filter cotton or a filter net. One end of the limiting plate 14 can be rotatably mounted on the filter box 9 through a rotating shaft or a hinge, and a buckle 15 is fixed at the other end. A clamping groove capable of cooperating with the buckle 15 is provided on the filter box 9. In addition, those skilled in the art can also install the limiting plate 14 in other ways to achieve the detachable connection of the limiting plate 14 on the filter box 9, which will not be elaborated here.

[0040] During the actual application process, the operator can first rotate and open the limiting plate 14, then place the filter box 9 on the overflow pipe 2, and use the recessed portion 12 on the filter box 9 to cooperate with the overflow pipe 2 to achieve the limiting of the frame 6. Then the operator can rotate and close the limiting plate 14 so that the buckle 15 on the limiting plate 14 can cooperate with the clamping groove on the filter box 9 to achieve the fixation of the limiting plate 14 on the filter box 9. At this time, under the limitation of the limiting plate 14, the filter box 9 is less likely to be separated from the overflow pipe 2 under the action of water flow, so that the filter element 10 in the filter box 9 can continuously filter the water discharged through the overflow pipe 2 and prevent the overflow pipe 2 from being blocked.

[0041] This hatching device has a simple structure, is convenient for assembly, disassembly and cleaning, and has a good application effect. It can not only effectively adsorb impurities such as foam, egg membranes and dead eggs in the upper, middle and lower waters of the hatching barrel 1, effectively remove the waste produced by the hatching water body, but also fully aerate the hatching water body, keep the water quality of the hatching water body stable for a long time, and improve the hatching efficiency of fish eggs. During actual use, when the adsorption net 11 or the adsorption filter cotton 17 is dirty, the operator can open the limiting plate 14 and then lift the frame 6 upward, rinse it with clean water and put it back into the hatching barrel 1 to collect foam until the fry hatches. The assembly and cleaning of the filtering mechanism are convenient, and the use and maintenance are more convenient, reducing the use and maintenance difficulty of this hatching device.

[0042] The present invention provides a hatching device for hatching fish adhesive eggs, which has the advantages of simple structure, easy assembly and maintenance. By arranging an overflow pipe above the barrel body and a filtering mechanism at a position corresponding to the overflow pipe, the filtering mechanism can effectively adsorb and filter the dirt flowing with the bubble flow, thereby reducing the suspension amount of dirt in the water body of the hatching barrel, being beneficial to improving the cleanliness of the water body in the hatching barrel, ensuring the stability of the hatching water quality, and further being beneficial to improving the hatching efficiency of fish eggs.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
