Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to a circulating fish egg incubator. Background Art

[0002] In the aquaculture industry, traditional fish egg hatching is usually carried out by pond still water hatching, running water hatching and water sprinkling hatching, which are easily affected by the external temperature environment and the hatching environment is not easy to control, resulting in low hatching rate of fish eggs and long hatching period. With the development of technology, the hatching of fish eggs in the industry has gradually turned to indoor completion, such as the application of barrel incubators, which is convenient for controlling the hatching temperature environment and the quality of the hatching water body, which helps to improve the hatching rate and shorten the hatching period. However, in the barrel incubator, the volume of the barrel is limited, and the fish eggs are prone to sticking to each other and sinking to the bottom after being placed in the barrel, resulting in the phenomenon of fish eggs overlapping each other and lack of oxygen and death in local areas. In the prior art, a water injection pipe is usually provided in the barrel incubator, so that the outlet end of the water injection pipe is close to the bottom of the barrel, and the water body in the barrel can be driven to flow during the water injection process, which can reduce the sticking of fish eggs to each other and the sinking of fish eggs to the bottom to a certain extent. However, in this type of incubator, the fish eggs only rotate in one direction with the flow direction of the water body, and the sticky fish eggs are difficult to separate, and the hatching rate of fish eggs still has room for further improvement.

[0019] The technical solution of the present utility model is further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present utility model is not limited to the following.

[0020] like Figures 1 to 3 As shown, the circulating fish egg incubator comprises a hatching bucket 1, and a water inlet 2 is arranged at the bottom center of the hatching bucket 1, and the water inlet direction of the water inlet 2 substantially coincides with the central axis of the hatching bucket 1. A plurality of water inlet nozzles 3 are also arranged in the hatching bucket 1, and the plurality of water inlet nozzles 3 are evenly arranged in a circle with the central axis position of the hatching bucket 1 as the center, and the water inlet nozzles 3 are fixedly arranged at the bottom of the hatching bucket 1, and the water inlet end of the water inlet nozzle 3 is connected with the outside of the hatching bucket 1, and the water outlet ends of the plurality of water inlet nozzles 3 spray inward, and the spraying direction thereof deviates from the center of the distribution circle by a certain angle, so that the water body in the hatching bucket 1 can be driven to rotate when the water flow is sprayed.

[0021] When in use, the circulating fish egg incubator is used in conjunction with an external water pumping system, which includes an external water pump and an external water storage tank. The water inlet 2 and a plurality of water inlet nozzles 3 are both connected to the outlet end of the external water pump through a control valve, and the inlet end of the external water pump is connected to the external water storage tank. A water outlet is arranged on the top of the hatching bucket 1 to be connected to the external water storage tank. When in use, the fish eggs are suspended in the water in the hatching bucket 1, and the external water pump is started to pump water into the hatching bucket 1 through the water inlet 2 and a plurality of water inlet nozzles 3. During the water pumping process: the water flow sprayed by each water inlet nozzle 3 can drive the water body in the hatching bucket 1 to rotate, which can effectively prevent the fish eggs from sticking to each other; the water flow sprayed upward by the water inlet 2 can, on the one hand, lift the water body in the hatching bucket 1, which can effectively prevent the fish eggs from sinking to the bottom and accumulating, and on the other hand, can drive the fish eggs to roll during the lifting process, that is, the fish eggs will further roll in addition to flowing in the direction of rotation of the water body, which can further prevent the fish eggs from sticking to each other. During the water pumping process, excess water in the hatching bucket 1 is discharged from the drain port on the top to the external water storage tank to complete purification, oxygenation and other operations. The external water pump can realize circulating water pumping by continuously working. In the process of water pumping, the fish eggs are rotated and tumbled by the setting of the water inlet 2 and a plurality of water inlet nozzles 3, which can reduce the sticking of fish eggs to each other and the sinking of fish eggs to the bottom, thereby ensuring the hatching rate of fish eggs. In addition, the overall structure of the circulating fish egg incubator is simple, easy to implement, and has a high value of promotion and application.

[0022] In specific implementation, the total water pressure of the water inlet nozzles 3 is greater than the water pressure of the water inlet 2. During the entire cycle hatching process, the water flow drives the water body to rotate mainly, and the water body is carried as a supplement. The water pressure of the water inlet 2 should not be too large to prevent the fish eggs from being subjected to excessive impact and the surrounding water flow carrying the fish eggs downward toward the bottom of the bucket due to excessive upward water flow in the center of the hatching bucket 1.

[0023] Furthermore, a boss 4 is formed at the bottom center of the hatching bucket 1 toward the top of the hatching bucket, the water inlet 1 is arranged at the center of the boss 4, and the water inlet nozzle 3 is arranged between the boss 4 and the barrel wall of the hatching bucket 1, that is, the water inlet nozzle 3 is arranged in the recessed area around the boss 4 at the bottom of the hatching bucket 1, and the position of the water inlet nozzle 3 is lower than the water inlet 1. The water flow sprayed by the water inlet nozzle 3 can drive the water body in the hatching bucket 1 to rotate, and combined with the lifting effect of the water flow sprayed by the water inlet 1, the fish eggs are relatively far away from the above-mentioned recessed area at the bottom of the hatching bucket 1, avoiding the direct impact of the water flow sprayed by the water inlet nozzle 3 on the fish eggs.

[0024] Furthermore, there is a smooth arc transition between the barrel wall and the barrel bottom of the hatching barrel 1 and between the barrel bottom of the hatching barrel 1 and the boss 4. The surface in this area is smooth without dead corners, thereby preventing the accumulation of fish eggs and sedimentation materials.

[0025] Furthermore, a drain port 5 is provided at the bottom of the hatching bucket 1, and the drain port 5 is provided between the barrel wall of the hatching bucket 1 and the boss 4. A plug is detachably connected to the drain port 5. When the hatching bucket 1 needs to be cleaned, the plug can be opened to drain the water in the hatching bucket 1 through the drain port 5.

[0026] Furthermore, a plurality of overflow holes 6 are provided on the upper part of the wall of the hatching bucket 1, and an overflow trough 7 is provided on the outer cover of the hatching bucket 1. The overflow holes 6 are connected to the overflow trough 7, and a water outlet hole 8 is provided at the bottom of the overflow trough 7. When circulating the water, the excess water in the hatching bucket 1 is discharged from the overflow holes 6 to the overflow trough 7, and finally discharged to the external water storage tank through the water outlet hole 8. In a specific implementation, a filter screen is installed on the inner side of the plurality of overflow holes 6 to filter the fish eggs and retain them in the hatching bucket 1 during drainage. The overflow method makes the drainage pressure of the hatching bucket 1 low and evenly distributed, reducing the impact of the fish eggs carried by the water flow on the filter screen during drainage.

[0027] Furthermore, a top cover 9 is provided on the top of the hatching bucket 1, and the top cover 9 can cover the hatching bucket 1, and the top cover 9 can be conveniently opened to facilitate operations such as putting in fish eggs or taking out fry.
