Description

Technical Field

[0001] This invention relates to the field of fish farming, specifically to an incubation device for breeding black sea bream. Background Technology

[0002] Black sea bream, also known as black snapper, black sea bream, and sea bream, is a warm-water bottom-dwelling fish widely distributed along the coast of China and the waters of East Asia. The artificial incubation of black sea bream eggs requires strict control of environmental factors such as water quality, temperature, and dissolved oxygen, as well as attention to egg disinfection and disease prevention.

[0003] Black sea bream eggs typically require incubation boxes or hatching ponds for hatching. Fertilized eggs are placed evenly in the incubation equipment. During this period, unfertilized or dead eggs need to be checked and removed regularly. After a period of incubation, the fry will hatch. Dead eggs produced during the hatching process of black sea bream need to be dealt with promptly, otherwise they will pollute the water quality, spread bacteria, and seriously affect the hatching rate of healthy eggs. Since black sea bream eggs are buoyant, healthy eggs will float in the upper and middle layers of the water in the hatching pond, while dead eggs will gradually sink to the bottom. Existing incubation devices mostly use sieves for filtration. Dead eggs will leak through the mesh, while healthy eggs will be retained on the sieve. However, if the operator uses too much force during the sieving process, the sieve can squeeze the healthy eggs, causing them to break. This makes the operation difficult and may result in some eggs being missed. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This invention utilizes a cleaning mechanism to open the bottom of the hatching tank by taking advantage of the buoyancy of black sea bream eggs. This allows dead eggs and silt to be discharged directly downwards, and increases the open area of ​​the bottom of the hatching tank, facilitating the rapid discharge of dead eggs and silt. This solves the problem that traditional screens can easily cause healthy eggs to break, thus achieving a rapid egg release effect.

[0018] 2. This invention uses a water-separating mechanism to divide the water in the hatching tank into two layers: healthy eggs are located above the sealing strip, while dead eggs are located below it. When the sealing plate is tilted open, the water below the sealing strip can be drained, preventing excessive water discharge and ensuring the normal discharge of dead eggs and silt impurities, thereby achieving the effect of egg release.

[0019] 3. The present invention uses a material handling mechanism to filter the discharged water through a filter plate, allowing dead eggs and silt impurities to remain on the filter plate. This facilitates the pulling of the frame to recover the dead eggs and silt impurities on the filter plate. During the movement of the frame, the T-shaped sliding rod pulls the baffle to move. The drainage holes on the baffle are offset from the filter holes on the filter plate, thus sealing the filter plate and preventing residual water from flowing downwards, thereby improving the convenience of material discharge.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figures 1-8 The illustration shows a hatching device for breeding black sea bream, comprising a hatching tank 1 and a feeder 2 installed on top of the hatching tank 1. A transparent glass plate is provided on the outer side of the hatching tank 1. The feeder 2 is connected to the top of the hatching tank 1 via a feed pipe 3 to inject fish food into the hatching tank 1. A water injection pipe 4 is fixedly installed on the left side of the hatching tank 1 for injecting water into the hatching tank 1. A discharge valve 5 is fixedly installed on the outer side of the hatching tank 1 for feeding fish eggs into the hatching tank 1. A discharge box 6 is fixedly installed at the bottom of the hatching tank 1 for discharging silt, impurities, and dead eggs from the bottom of the hatching tank 1. The device also includes: a cleaning mechanism for quickly discharging dead eggs and silt from the bottom of the hatching tank 1, installed at the bottom of the hatching tank 1; a water-separating mechanism for separating dead eggs from healthy eggs in the hatching tank 1, installed on the inner side of the hatching tank 1; and a material-retrieving mechanism for recycling the discharged dead eggs and silt, installed on the inner side of the discharge box 6.

[0031] The cleaning mechanism includes a base plate 7 fixedly installed at the bottom of the incubation pool 1. Multiple equidistant discharge ports are opened on the surface of the base plate 7. A sealing plate 8 is rotatably installed inside each discharge port. When the sealing plate 8 is laid flat, it seals the discharge ports, thus sealing the bottom of the incubation pool 1. A first mounting rod 9 is rotatably installed on one side of the sealing plate 8. A gear 10 is fixedly installed at the end of the first mounting rod 9 away from the sealing plate 8. A first mounting cavity is opened on the surface of the base plate 7. Multiple rack plates 11, each engaging with a gear 10, are arranged inside the first mounting cavity. When the rack plates 11 move, they drive the gears 10 to rotate, which in turn drives the first mounting rod 9 to rotate, tilting the sealing plate 8 and opening the discharge ports. Eggs and silt impurities can enter the discharge box 6 with the water flow. A prismatic rod 12 is fixedly installed between multiple toothed plates 11. Multiple equidistant positioning frames 13 are slidably installed on the outer side of the prismatic rod 12. The positioning frames 13 are fixedly installed inside the first mounting cavity of the bottom plate 7, providing support for the prismatic rod 12. Multiple equidistant mounting blocks 14 are fixedly installed on the outer side of the prismatic rod 12. A connecting rod 15 is hinged to the top of the mounting block 14. Two symmetrically distributed inclined plates 21 are fixedly installed between the inner side of the hatching tank 1 and the top of the bottom plate 7, allowing dead eggs and silt impurities to be guided above the sealing plate 8. A pressure plate 16 is provided at the bottom of the inclined plate 21. The end of the connecting rod 15 away from the mounting block 14 is hinged to the bottom of the pressure plate 16. Multiple equally spaced support rods 17 are fixedly installed at the bottom of the pressure plate 16. A sleeve plate 18 is slidably installed on the outer side of the support rods 17. The sleeve plate 18 is fixedly installed on the top of the base plate 7, so that the pressure plate 16 can drive the support rods 17 to move vertically along the outer side of the sleeve plate 18, improving the stability of the movement of the pressure plate 16. A first spring 19 is fixedly installed between the pressure plate 16 and the sleeve plate 18. The rebound force of the first spring 19 can be used to facilitate the movement and reset of the pressure plate 16. An adjustment handle 20 that slides to the outer side of the incubation tank 1 is fixedly installed on the outer side of the pressure plate 16. An elongated groove is opened on the outer side of the incubation tank 1 for the adjustment handle 20 to be limited and slid. When the adjustment handle 20 is pulled down, it can drive the pressure plate 16 down. The pressure plate 16 is pushed by the connecting rod 15. The installation block 14 moves, which in turn drives the prismatic rod 12 to move horizontally along the inner side of the positioning frame 13. The prismatic rod 12 drives the rack plate 11 to contact the gear 10, realizing the flipping of the sealing plate 8. This ensures the discharge of dead eggs without affecting healthy eggs. Two symmetrically distributed rubber plates 39 are fixedly installed on the outer side of the sealing plate 8, and the rubber plates 39 are in contact with the inner side of the discharge port of the bottom plate 7, improving the sealing performance between the sealing plate 8 and the discharge port. Multiple equidistant guide strips 40 are fixedly installed on the top of the bottom plate 7. The outer side of the guide strips 40 has a beveled structure, and the guide strips 40 are staggered with the sealing plate 8, so that the guide strips 40 can guide the dead eggs to the top of the sealing plate 8, making it easier for the sealing plate 8 to discharge the dead eggs when it flips.A second mounting rod 41 is fixedly installed on the side of the sealing plate 8 away from the first mounting rod 9. A second mounting cavity is formed on the surface of the sealing plate 8, and the second mounting rod 41 extends into the inner side of the second mounting cavity, so that the second mounting rod 41 can provide auxiliary support for one side of the sealing plate 8 and improve the stability of the rotation of the sealing plate 8. A swing rod 42 is fixedly installed on the outer side of the second mounting rod 41, and multiple arc-shaped slides 43 distributed at equal intervals are fixedly installed on the inner side of the second mounting cavity. The swing rod 42 is slidably installed on the outer side of the adjacent arc-shaped slides 43. On the side, an arc-shaped spring 44 is fixedly installed between the outer side of the rocker arm 42 and one end of the arc-shaped slide 43. This allows the sealing plate 8 to move along the outer side of the arc-shaped slide 43 via the second mounting rod 41, compressing the arc-shaped spring 44. This allows the sealing plate 8 to quickly reset using the rebound force of the arc-shaped spring 44. Furthermore, the arc-shaped slide 43, positioned by the rocker arm 42, provides a limit to the rotation of the sealing plate 8, ensuring that the sealing plate 8 is horizontal after reset.

[0032] Example 2: Please refer to Figures 1-6This embodiment further illustrates Example 1. The water-blocking mechanism shown in the figure includes a winding box 22 fixedly installed on the outside of the incubation tank 1. A sealing strip 23, which cooperates with the winding box 22, is slidably installed on the inside of the incubation tank 1. The sealing strip 23 is made of metal. A rubber sleeve 24 is fixedly installed on the outside of the inclined plate 21 on the left side of the bottom plate 7. The sealing strip 23 is slidably installed on the inside of the rubber sleeve 24. A movable plate 25 is fixedly installed on the end of the sealing strip 23 away from the winding box 22. Two symmetrically distributed screws 26 are rotatably installed between the two inclined plates 21. The movable plate 25 is threaded onto the outside of the screws 26. When the two screws 26 rotate, they can drive the moving plate 25 to move horizontally along the inner side of the incubation tank 1, thereby stretching the sealing strip 23. An installation box 27 is fixedly installed on the outer side of the incubation tank 1. One end of the screw 26 extends to the inner side of the installation box 27. A synchronous belt 28 is rotatably installed between the two screws 26. A drive motor 29 is fixedly installed on the outer side of the installation box 27. The output end of the drive motor 29 is fixedly connected to one end of the adjacent screw 26, so that when the drive motor 29 is running, it can drive the corresponding screw 26 to rotate. This screw 26 can drive the other screw 26 to rotate synchronously via the synchronous belt 28. A triangular protrusion is provided on the top of the pressure plate 16, and an elastic push plate 30 is provided on the inclined surface of the triangular protrusion. The elastic push plate 30 is slidably installed on the inner side of the adjacent inclined plate 21, so that when the elastic push plate 30 moves, it can push the pressure plate 16 downward through the triangular protrusion on the top of the pressure plate 16. A stop plate 31 is fixedly installed on the side of the moving plate 25 away from the sealing strip 23, and the stop plate 31 and the elastic push plate 30 are on the same horizontal line, so that when the moving plate 25 moves, the stop plate 31 can contact the elastic push plate 30, and the stop plate 31 can push the pressure plate 16 downward through the elastic push plate 30, thereby opening the sealing plate 8. The sealing strip 23 divides the water in the hatching tank 1 into two layers: healthy eggs are located above the sealing strip 23, and dead eggs are located below the sealing strip 23. This prevents excessive water discharge when the sealing plate 8 is opened. Both sides of the movable plate 25 are inclined structures, and the inclination angle of the movable plate 25 corresponds to that of the two inclined plates 21, making it easy for the movable plate 25 to adhere to the outer side of the inclined plate 21. Two symmetrically distributed rubber baffles are fixedly installed on the inner side of the hatching tank 1, and the rubber baffles are located above the sealing strip 23, allowing the sealing strip 23 to move along the bottom of the rubber baffles, thereby improving the sealing performance between the sealing strip 23 and the rubber baffles.

[0033] Example 3: Please refer to Figures 2-8This embodiment further illustrates other embodiments. The material handling mechanism shown in the figure includes a pull frame 35 slidably installed inside the discharge box 6. A filter plate 32 is fixedly installed inside the pull frame 35, which can filter the water entering the discharge box 6, causing dead eggs and silt impurities to remain on the top of the filter plate 32, facilitating the recycling of dead eggs and silt impurities. When the pull frame 35 is pulled, the dead eggs and silt impurities on the filter plate 32 can be removed. A drain valve 33 is fixedly installed at the bottom of the discharge box 6, and the filtered water can be discharged outward from the drain valve 33. A baffle 34 is provided at the bottom of the filter plate 32. Multiple equally spaced drainage holes are provided on the surface of the baffle 34, and these drainage holes are aligned with the filter holes on the filter plate 32, allowing water passing through the filter plate 32 to drain downwards through the drainage holes of the baffle 34. Two symmetrically distributed abutment rods 36 are fixedly installed on the outer side of the baffle 34. The abutment rods 36 slide through the pull frame 35 and contact the inner side of the discharge box 6. A T-shaped sliding rod 37 is fixedly installed at the end of the baffle 34 away from the abutment rods 36. The T-shaped sliding rod 37 slides through the discharge box 6, and one end of the T-shaped sliding rod 37... A second spring 38 is fixedly installed between the end of the pull frame 35 and the outside of the discharge box 6. When the pull frame 35 is inserted into the inside of the discharge box 6, the abutment rod 36 contacts the inside of the discharge box 6. Using the reaction force of the discharge box 6 on the abutment rod 36, the abutment rod 36 drives the baffle 34 to move along the bottom of the filter plate 32. The second spring 38 is stretched by the T-shaped slide rod 37, so that the drainage hole on the baffle 34 is aligned with the filter plate 32. Thus, when the pull frame 35 is taken out of the discharge box 6, the rebound force of the second spring 38 makes the drainage hole on the baffle 34 aligned with the filter plate 32. The filter holes on plate 2 are staggered to seal the filter holes of filter plate 32, making it easy for workers to remove dead eggs and silt impurities. A sleeve is provided on the outer side of the pull frame 35 for the T-shaped slide rod 37 to limit its sliding, improving the stability of the T-shaped slide rod 37's movement. A buckle plate 45 is rotatably installed on the end of the pull frame 35 near the abutment rod 36. A through hole is provided on the outer side of the discharge box 6 for the buckle plate 45 to be inserted into, so that when the pull frame 35 is inserted into the discharge box 6, the buckle plate 45 can be rotated downwards, so that the buckle plate 45 abuts against the outer side of the discharge box 6, thereby locking the pull frame 35 and facilitating installation and disassembly.

[0034] Working principle: First, the operator starts the drive motor 29, which drives the corresponding screw 26 to rotate. This screw 26 can drive another screw 26 to rotate synchronously via the synchronous belt 28. The two screws 26 then drive the moving plate 25 to move horizontally along the inner side of the incubation tank 1. The moving plate 25 pulls the sealing strip 23 to move along the inner side of the incubation tank 1. When the moving plate 25 contacts the inclined plate 21 located on the right side of the bottom plate 7, the abutment 31 on the moving plate 25 contacts the elastic push plate 30, causing the abutment 31 to push the elastic push plate 30 to move. The elastic push plate 30 moves along the inclined surface of the triangular protrusion on the pressure plate 16. With the cooperation of the support rod 17 and the sleeve plate 18, the elastic push plate 30 can move horizontally. The triangular protrusion pushes the pressure plate 16 downward, compressing the first spring 19. The pressure plate 16, through the connecting rod 15, pushes the mounting block 14 to move, causing the mounting block 14 to push the prismatic rod 12 to move horizontally along the inner side of the positioning frame 13. The prismatic rod 12 can then drive the rack plate 11 to contact the gear 10. The gear 10 drives the corresponding sealing plate 8 to rotate through the first mounting rod 9. At the same time, the sealing plate 8 drives the second mounting rod 41 to rotate synchronously. The second mounting rod 41 drives the swing rod 42 to move along the outer side of the arc-shaped slide 43, compressing the arc-shaped spring 44. The sealing plate 8 can then be tilted, opening the drain outlet on the bottom plate 7. Simultaneously, the sealing strip 23 divides the water in the incubation tank 1 into upper and lower sections. The layers are arranged so that healthy eggs are above the sealing strip 23 and dead eggs are below it. Water below the sealing strip 23 can drain into the discharge box 6. Dead eggs and silt impurities on the sealing plate 8 enter the discharge box 6 along with the water flow. Then, the falling water flows through the filter plate 32 in the pull frame 35 into the bottom of the discharge box 6 and is discharged outward from the drain valve 33. Dead eggs and silt impurities remain on the top of the filter plate 32. At this time, the drive motor 29 drives the corresponding screw 26 to rotate in the opposite direction, causing the moving plate 25 to move and reset, retracting the sealing strip 23 into the winding box 22. The rebound force of the first spring 19 and the arc spring 44 causes the sealing plate 8 to rotate and reset. The sealing plate 8 can then rotate and close the drain of the bottom plate 7. The water inlet is used to seal the hatching tank 1. Finally, the staff opens the water inlet pipe 4 to add water to the hatching tank 1, and rotates the buckle plate 45 to align with the perforation on the discharge box 6. The pull frame 35 is then pulled out of the discharge box 6. Using the rebound force of the second spring 38, the second spring 38 pushes the T-shaped slide rod 37 to move. The T-shaped slide rod 37 pulls the baffle 34 to move along the bottom of the filter plate 32, so that the drain hole on the baffle 34 is misaligned with the filter hole on the filter plate 32, thus sealing the filter hole of the filter plate 32. The staff can then collect the dead eggs and silt impurities on the filter plate 32, thus completing the treatment of dead eggs. In this process, healthy eggs will not be contacted, thereby achieving the effect of egg release and improving the convenience of dead egg treatment.
