Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to a fish spawning device for artificial breeding. Background Technology

[0002] The Huazi fish is a freshwater fish belonging to the Cyprinidae family and the Leuciscus genus. Its scientific name is Leuciscus var. ...

[0003] Fish spawning refers to the reproductive behavior of female fish releasing mature eggs from their bodies, where fertilization and embryonic development occur under specific conditions. However, some fish eggs are not fully developed and are considered dead eggs. Dead eggs provide a breeding ground for pathogens such as bacteria and fungi, increasing the risk of disease transmission. The removal of dead eggs in traditional spawning devices mainly relies on manual operation, such as using droppers or nets to pick out dead eggs one by one. This method is not only inefficient but also labor-intensive and cannot meet the needs of large-scale breeding.

[0004] Therefore, it is necessary to provide a new spawning device for artificial fish breeding to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the technical problem that traditional spawning devices rely heavily on manual labor for cleaning dead eggs, which is not only inefficient but also labor-intensive, this invention provides a spawning device for artificial fish breeding.

[0006] The fish artificial breeding spawning device provided by this utility model includes: a spawning box, wherein a funnel-shaped spawning plate is provided inside the spawning box, and a biomimetic fiber layer is provided on the funnel-shaped spawning plate; two support rods, both of which are mounted on the spawning box, and the bottom ends of both support rods are fixed to the funnel-shaped spawning plate; a sieving mechanism, which is provided on the spawning box and is used to shake dead eggs off the funnel-shaped spawning plate; and a cleaning mechanism, which is provided on the spawning box and is used to clean dead eggs from the spawning box.

[0007] Preferably, the screening mechanism includes a protective box, a micro motor, a cam, a push rod, and a wheel. The protective box is located on one side of the spawning box.

The wheel is rotatably installed on the push rod and is in contact with the cam.

[0008] Preferably, the cleaning mechanism includes a collection box, a suction pump, an inlet tube, and an outlet tube. The collection box is fixedly installed on one side of the spawning box, the suction pump is fixedly installed on one side of the spawning box, the inlet tube is fixedly connected to the inlet end of the suction pump and is connected to the spawning box, the outlet tube is fixedly connected to the outlet end of the suction pump and is connected to the collection box.

[0009] Preferably, a bracket is fixedly installed on the inner wall of the collection box, a collection box is mounted on the bracket, and a cleaning door is hinged to one side of the collection box.

[0010] Preferably, a guide cylinder is fixedly installed on one side of the spawning box, a guide rod is slidably installed on the guide cylinder, the top end of the guide rod is fixed to the support rod, and a return spring is fixedly installed inside the guide cylinder, the return spring being sleeved on the outside of the guide rod.

[0013] Compared with related technologies, the fish spawning device for artificial breeding provided by this utility model has the following beneficial effects:

[0014] This utility model provides a fish spawning device for artificial breeding:

[0015] 1. The funnel-shaped spawning plate and biomimetic fiber layer provide favorable spawning conditions for the spawning organisms, which is conducive to improving the number of eggs laid and the survival rate of eggs. At the same time, the coordinated design of the screening and cleaning mechanisms with the spawning box makes the entire device compact and functional, effectively completing the cleaning of dead eggs. Through the cooperation of the cam and the wheel, the rotation of the cam is converted into the reciprocating motion of the push rod, which in turn drives the support rod and the funnel-shaped spawning plate to vibrate. This mechanical transmission method can produce a relatively regular and effective vibration, which is conducive to shaking off the dead eggs on the funnel-shaped spawning plate and improving the effect of dead egg cleaning.

[0016] 2. The suction force generated by the suction pump, along with the airflow channel formed by the inlet and outlet tubes, can quickly suck up dead eggs from the spawning box and transport them to the collection box, greatly improving the convenience and efficiency of dead egg cleaning. Compared with traditional manual cleaning methods, it saves a lot of time and manpower. The collection box allows dead eggs to be collected in a separate container. When it is necessary to clean dead eggs, simply remove the collection box; there is no need to clean the entire collection box, which greatly simplifies the dead egg handling process and improves work efficiency.

[0017] 3. The guide cylinder and guide rod work together to guide the movement of the support rod. During the screening process, the return spring can store elastic potential energy and push the guide rod and support rod to automatically reset. The heating tube can adjust the water temperature in the spawning tank according to the needs of the organisms, providing a good physiological environment for the spawning organisms and improving the success rate of spawning and the hatching rate of eggs. The light lamp can simulate natural sunlight and provide a stable light rhythm for the spawning organisms. Suitable light conditions can stimulate the reproductive desire of the spawning organisms and improve the spawning rate. Attached Figure Description

[0025] The fish artificial breeding spawning device includes: a spawning box 1, which has a funnel-shaped spawning plate 2 inside, and a biomimetic fiber layer 3 on the funnel-shaped spawning plate 2; two support rods 4, both of which are mounted on the spawning box 1 and fixed at their bottom ends to the funnel-shaped spawning plate 2; a sieving mechanism, which is located on the spawning box 1 and is used to shake dead eggs off the funnel-shaped spawning plate 2; and a cleaning mechanism, which is located on the spawning box 1 and is used to clean dead eggs from the spawning box 1. The funnel-shaped spawning plate 2 and the biomimetic fiber layer 3 provide favorable spawning conditions for the spawning organisms, which is beneficial to increasing the spawning volume and egg survival rate. Furthermore, the coordinated design of the sieving mechanism and the cleaning mechanism with the spawning box 1 makes the entire device compact and functionally complete, effectively completing the dead egg cleaning work.

[0026] The screening mechanism includes a protective box 5, a micro motor 6, a cam 7, a push rod 8, and a wheel 9. The protective box 5 is located on one side of the spawning box 1. The micro motor 6 is fixedly installed inside the protective box 5. The cam 7 is connected to the output shaft of the micro motor 6 via a coupling. The push rod 8 is fixedly installed on the support rod 4. The wheel 9 is rotatably installed on the push rod 8 and contacts the cam 7. Through the cooperation between the cam 7 and the wheel 9, the rotation of the cam 7 is converted into the reciprocating motion of the push rod 8, which in turn drives the support rod 4 and the bucket-shaped spawning plate 2 to vibrate. This mechanical transmission method can produce relatively regular and effective vibration, which is beneficial for fully shaking off dead eggs on the bucket-shaped spawning plate 2 and improving the effect of dead egg removal.

[0027] The cleaning mechanism includes a collection box 10, a suction pump 11, an inlet tube 12, and an outlet tube 13. The collection box 10 is fixedly installed on one side of the spawning box 1, and the suction pump 11 is fixedly installed on one side of the spawning box 1. The inlet tube 12 is fixedly connected to the inlet end of the suction pump 11 and is connected to the spawning box 1. The outlet tube 13 is fixedly connected to the outlet end of the suction pump 11 and is connected to the collection box 10. Through the suction force generated by the suction pump 11 and the airflow channel formed by the inlet tube 12 and the outlet tube 13, dead eggs in the spawning box 1 can be quickly sucked in and transported to the collection box 10, which greatly improves the convenience and efficiency of dead egg cleaning and saves a lot of time and manpower compared with traditional manual cleaning methods.

[0028] A bracket 14 is fixedly installed on the inner wall of the collection box 10, and a collection box 15 is mounted on the bracket 14. A cleaning door is hinged to one side of the collection box 10. The collection box 15 allows dead eggs to be collected in a separate container. When it is necessary to clean the dead eggs, only the collection box 15 needs to be removed. There is no need to clean the entire collection box 10, which greatly simplifies the operation process of dead egg processing and improves work efficiency.

[0029] A guide cylinder 16 is fixedly installed on one side of the spawning box 1. A guide rod 17 is slidably installed on the guide cylinder 16. The top end of the guide rod 17 is fixed to the support rod 4. A return spring 18 is fixedly installed inside the guide cylinder 16. The return spring 18 is sleeved on the outside of the guide rod 17. Through the cooperation of the guide cylinder 16 and the guide rod 17, the movement of the support rod 4 is guided. During the screening process, the return spring 18 can store elastic potential energy and push the guide rod 17 and the support rod 4 to automatically reset.

[0030] Heating pipes 19 for regulating water temperature are fixedly installed on both inner walls of the spawning box 1. The heating pipes 19 can adjust the water temperature in the spawning box 1 according to the needs of the organisms, which can provide a good physiological environment for the spawning organisms and improve the success rate of spawning and the hatching rate of the eggs.

[0031] A light lamp 20 for simulating sunlight is fixedly installed on one inner wall of the spawning box 1. The light lamp 20 can simulate natural sunlight and provide a stable light rhythm for the spawning organisms. Suitable light conditions can stimulate the reproductive desire of the spawning organisms and increase the spawning rate.

[0032] It is worth noting that the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0033] The working principle of the fish spawning device for artificial breeding provided by this utility model is as follows:

[0034] In use, the biomimetic fiber layer 3 on the bucket-shaped spawning plate 2 provides a suitable spawning environment for the spawning organisms, attracting them to lay eggs. After a period of spawning, dead eggs may appear on the bucket-shaped spawning plate 2. The micro motor 6 is then activated, and its output shaft drives the cam 7 to rotate via a coupling. Since the push rod 8 is fixedly mounted on the support rod 4, and the wheel 9 is rotatably mounted on the push rod 8 and in contact with the cam 7, as the cam 7 rotates, its contour continuously pushes the wheel 9. The wheel 9, under the thrust of the cam 7, drives the push rod 8 to move, causing the support rod 4 to shake. Because the top of the guide rod 17 is fixed to the support rod 4, and the guide rod 17 is slidably mounted on... Inside the guide cylinder 16 on one side of the spawning box 1, the shaking of the support rod 4 will cause the guide rod 17 to slide up and down inside the guide cylinder 16. At this time, the return spring 18 will be squeezed or stretched by the guide rod 17. As the cam 7 continues to rotate, its thrust on the wheel 9 gradually decreases. Due to its own elastic restoring force, the return spring 18 will push the guide rod 17 to slide in the opposite direction inside the guide cylinder 16, causing the support rod 4 to return to the initial position, preparing for the next screening. This cycle repeats, realizing the continuous shaking of the bucket-shaped spawning plate 2 (frequency between 50-100Hz). Dead eggs, due to their weak adhesion, fall to the bottom of the spawning box 1 first, while live eggs remain on the bucket-shaped spawning plate 2.

[0035] After the screening mechanism shakes the dead eggs off the hopper-shaped egg-laying plate 2, the suction pump 11 is started. The suction pump 11 starts working. Under the action of the suction pump 11, the dead eggs in the egg-laying box 1 will enter the inlet end of the suction pump 11 through the inlet tube 12 connected to the egg-laying box 1 with the airflow. Then, the dead eggs will be transported from the outlet end of the suction pump 11 through the outlet tube 13 to the collection box 15 connected to the outlet end of the outlet tube 13 with the airflow. When the dead eggs in the collection box 15 accumulate to a certain amount and need to be cleaned, the staff will open the cleaning door hinged on one side of the collection box 10, remove the collection box 15 from the support 14, process the dead eggs in the collection box 15, and put the collection box 15 back on the support 14 after processing and close the cleaning door.

[0036] When the water temperature in the spawning tank 1 is lower than the suitable temperature range for spawning, the heating tube 19 is turned on. After the heating tube 19 is powered on, it starts to heat up and transfers heat to the water in the spawning tank 1 to maintain the water temperature within a suitable range.

[0037] When a simulated sunlight environment is needed, the light lamp 20 is turned on. The light lamp 20 emits light to illuminate the inside of the spawning box 1, providing light conditions for the spawning organisms. The on and off times of the light lamp 20 can be set according to the natural life rhythm of the organisms. For example, to simulate the alternation of day and night, the light lamp 20 is turned on during the daytime and turned off during the nighttime. At the same time, the light intensity and duration of the light lamp 20 can be adjusted according to the different growth stages or spawning cycles of the organisms to achieve the best simulation effect.

[0038] Compared with related technologies, the fish spawning device for artificial breeding provided by this utility model has the following beneficial effects:

[0039] This utility model provides a fish spawning device for artificial breeding. Through the bucket-shaped spawning plate 2 and the biomimetic fiber layer 3, it provides good spawning conditions for spawning organisms, which is conducive to improving the spawning volume and egg survival rate. At the same time, the coordinated design of the screening mechanism and cleaning mechanism with the spawning box 1 makes the whole device compact and functional, and can effectively complete the cleaning of dead eggs. Through the cooperation of cam 7 and wheel 9, the rotation of cam 7 is converted into the reciprocating motion of push rod 8, which in turn drives support rod 4 and bucket-shaped spawning plate 2 to vibrate. This mechanical transmission method generates relatively regular and effective shaking, which helps to fully shake off dead eggs from the spawning plate 2, improving the effectiveness of dead egg removal. The suction force generated by the pump 11, along with the airflow channel formed by the inlet tube 12 and outlet tube 13, quickly draws dead eggs from the spawning box 1 and transports them to the collection box 10, greatly improving the convenience and efficiency of dead egg removal. Compared to traditional manual removal methods, it saves a significant amount of time and manpower. The collection box 15 allows dead eggs to be collected in a separate container; when it's time to remove dead eggs, simply remove the collection box 15, eliminating the need to clean the entire collection box 10. The process of handling dead eggs is greatly simplified, and work efficiency is improved. The guide cylinder 16 and guide rod 17 work together to guide the movement of the support rod 4. During the screening process, the return spring 18 can store elastic potential energy and push the guide rod 17 and support rod 4 to automatically reset. The heating tube 19 can adjust the water temperature in the spawning tank 1 according to the needs of the organisms, which can provide a good physiological environment for the spawning organisms, improve the success rate of spawning and the hatching rate of eggs. The light lamp 20 can simulate natural sunlight and provide a stable light rhythm for the spawning organisms. Suitable light conditions can stimulate the reproductive desire of the spawning organisms and improve the spawning rate.
