Description

Technical Field

[0001] This invention relates to the field of poultry breeding equipment technology, specifically to a breeding poultry incubation and rearing device. Background Technology

[0002] Breeding and raising of breeding poultry is a core link in the breeding system of superior livestock and poultry breeds. Especially for the selection and breeding of specific breeds of breeding poultry such as rare breeds and special superior strains, the embryonic development has extremely high requirements for the precision of the incubation environment, the independence of individual management, and the flexibility of egg body adaptation. It directly determines the purity of the breeding poultry, the survival rate, and the stability of the superior traits.

[0003] Currently, most mainstream poultry hatching and rearing devices on the market are designed and developed around large-scale, intensive commercial poultry farming. They generally adopt a large-volume integrated hatching chamber structure, which cannot independently control the hatching units. Hatching parameters such as temperature, humidity, and airflow velocity cannot be finely and differentiated according to the developmental characteristics of specific breeds of poultry embryos. The egg-bearing and egg-turning structures of the equipment are fixed designs, only suitable for conventionally sized poultry eggs. They cannot be flexibly adjusted for irregularly shaped or specially sized eggs of specific breeds of poultry. Large-scale chambers cannot achieve isolated rearing of small batches of single groups of poultry eggs. Environmental cross-interference is likely to occur between different breeding samples, which cannot meet the core requirements of individual traceability and purebred breeding in the process of selective breeding of poultry. The heating and humidification systems of existing devices are independent of each other, and there are ventilation dead zones in the airflow circulation, resulting in serious heat loss. Moreover, the energy-consuming structure designed for large-volume chambers has extremely low energy efficiency when used for small-batch selective breeding of poultry, resulting in high operating costs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that existing incubation devices cannot meet the needs of breeding poultry selection and cultivation, and a breeding poultry incubation and cultivation device is provided.

[0005] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: A breeding poultry hatching and rearing device includes a box body. The back of the box body is provided with a clean air main pipe, an exhaust main pipe, a hot water supply pipe, and a hot water return pipe. The clean air main pipe is connected to an external clean air device, the exhaust main pipe is connected to an external exhaust pump, and the hot water supply pipe and the hot water return pipe are connected to an external electric water heater.

[0006] The chamber contains multiple main chambers. An atomizer is located on one side of each main chamber. A horizontally placed incubation tube is located inside the main chamber. Heat exchange fins are arranged around the outside of the incubation tube. Hot water supply pipes deliver hot water to the heat exchange fins and discharge it through hot water return pipes. A grid is arranged around one end of the incubation tube to connect the main chamber with the inside of the incubation tube. A clean air main pipe brings clean air into the main chamber. The atomizer generates water mist to humidify the clean air. The heat exchange fins transfer heat from the external hot water to the clean air for heating. The heated and humidified clean air enters the incubation tube through the grid. The exhaust main pipe discharges the air from the incubation tube. The eggs to be hatched are placed inside the incubation tube for incubation.

[0007] Furthermore, the incubation tube is equipped with a partition plate to divide the interior of the incubation tube into an incubation chamber and an equipment chamber, wherein the incubation chamber is connected to a grid and heat exchange fins are arranged on the outside of the incubation chamber.

[0008] Furthermore, the partition plate is equipped with exhaust vents, and the equipment compartment is equipped with an exhaust pipe. One end of the exhaust pipe is connected to the exhaust vent, and the other end is connected to the main exhaust pipe.

[0009] Furthermore, one end of the heat exchange fin is provided with an inlet ring pipe and the other end is provided with a return ring pipe. The hot water pipe inside the heat exchange fin is connected to the inlet ring pipe and the return ring pipe respectively. The inlet ring pipe is connected to the hot water supply pipe and the return ring pipe is connected to the hot water return pipe.

[0010] Furthermore, the main chamber is provided with an atomizing water tank, an atomizer is located at the bottom of the atomizing water tank, and an atomizing water supply pipe is connected to the bottom of the return water ring pipe, which extends to the top of the atomizing water tank to supply water into the atomizing water tank.

[0011] Furthermore, the main chamber has a front cover plate near the incubation chamber and a rear cover plate near the equipment chamber. The front cover plate has a door, and the front cover plate, door, and rear cover plate together seal the main chamber. The rear cover plate has an air inlet pipe that connects the clean air main pipe to the interior of the main chamber. The outer ring of the incubation tube is fitted with guide plates at both ends of the heat exchange fins. The guide plates have guide windows that cooperate with the heat exchange fins. The remaining positions are sealed. Under the guidance of the guide plates and guide windows, the airflow in the main chamber can only flow through the heat exchange fins.

[0012] Furthermore, the incubation chamber is equipped with a sliding cylinder that slides close to the inner wall of the incubation chamber. The sliding cylinder is equipped with a guide rod, and the partition plate is equipped with a guide hole that matches the guide rod. The guide rod extends into the equipment chamber, and the end of the guide rod is equipped with a connecting ring. An electric cylinder is installed in the equipment chamber, and the free end of the electric cylinder is connected to the connecting ring.

[0013] Furthermore, the partition plate is provided with a sleeve extending into the incubation chamber. The sleeve is slidably connected to a pull rod. The pull rod is bent in the middle and has a swing arm at the bend. The end of the swing arm is rotatably connected to a roller. The middle of the pull rod is provided with a vertically sliding buckle and a gate block. The middle of the pull rod is provided with a vertical sliding groove. A hand-tightening screw is rotatably provided on the buckle. The hand-tightening screw passes through the sliding groove and is threadedly connected to the gate block. The top of the buckle abuts against the bottom of the swing arm.

[0014] Furthermore, the equipment compartment is equipped with an egg-turning motor, which is powered by a gear one. An annular groove is provided on the partition plate, and a connecting bearing is slidably provided in the annular groove. The connecting bearing is rotatably connected to a gear two that meshes with the gear one. A shaft is provided on the gear two and extends into the incubation compartment. A roller is sleeved on the shaft.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] The enclosure is equipped with multiple independent main chambers and incubation tubes, which can realize small-batch, single-group isolated breeding of poultry eggs, eliminate cross-interference of different breeding samples, and meet the needs of individual traceability and purebred breeding for the selection and breeding of breeding poultry.

[0017] The incubation chamber has no dead corners for ventilation, uniform temperature and humidity throughout, and heat exchange fins surround the outer wall of the incubation chamber, which has both heating and insulation functions, greatly improving the stability of the incubation environment and reducing the energy consumption of the device.

[0018] The roller support structure has stepless height adjustment and can adapt to poultry eggs of different diameters, irregular shapes, and special sizes, making it far more versatile than fixed load-bearing structures.

[0019] The sliding cylinder can extend and move horizontally, retracting and sealing itself during incubation, and extending outside the chamber when the chicks are taken out, eliminating the need for manual entry into the chamber. This makes it convenient to operate and does not disturb the stable incubation environment. Attached Figure Description

Detailed Implementation

[0036] The present invention will now be described in further detail with reference to the accompanying drawings.

[0037] Combined with appendix Figure 1 and attached Figure 2A breeding poultry hatching and rearing device includes a box 1. The back of the box 1 is provided with a clean air main pipe 2, an exhaust main pipe 3, a hot water supply pipe 4, and a hot water return pipe 5. The clean air main pipe 2 is connected to an external clean air device, the exhaust main pipe 3 is connected to an external exhaust pump, and the hot water supply pipe 4 and the hot water return pipe 5 are connected to an external electric water heater.

[0038] Combined with appendix Figure 3 Appendix Figure 4 Appendix Figure 5 and attached Figure 6 The housing 1 has multiple main chambers 6. Atomizer 22 is provided on one side of the main chamber 6. A horizontally placed incubation tube 7 is provided in the main chamber 6. Heat exchange fins 26 are provided around the outside of the incubation tube 7. Hot water supply pipe 4 delivers hot water to the heat exchange fins 26 and discharges it through hot water return pipe 5. A grid 33 is provided around one end of the incubation tube 7 to connect the main chamber 6 with the inside of the incubation tube 7. Clean air main pipe 2 brings clean air into the main chamber 6. Atomizer 22 generates water mist to humidify the clean air. Heat exchange fins 26 transfer heat from the external hot water to the clean air for heating. The heated and humidified clean air enters the incubation tube 7 through the grid 33. Exhaust main pipe 3 exhausts the air from the incubation tube 7. The poultry eggs to be hatched are placed in the incubation tube 7 for incubation.

[0039] Clean air, acting as a temperature and humidity carrier, is atomized and humidified, and then heat-exchanged by fins to form a constant temperature and humidity clean airflow. This airflow is then evenly delivered into the incubation chamber through a grille. The closed-loop airflow circulation ensures that there are no dead corners in the chamber. At the same time, the heat exchange fins wrap around the outer wall of the incubation chamber, preventing heat loss from the chamber and achieving integrated heating and insulation, thus reducing energy consumption.

[0040] Combined with appendix Figure 5 and attached Figure 6 The incubation tube 7 is provided with a partition plate 23 to divide the interior of the incubation tube 7 into an incubation chamber 24 and an equipment chamber 25. The incubation chamber 24 is connected to the grid 33, and the heat exchange fins 26 are arranged on the outside of the incubation chamber 24.

[0041] Combined with appendix Figure 5 Appendix Figure 6 Appendix Figure 11 and attached Figure 12 The partition plate 23 is provided with an exhaust hole 31, and the equipment compartment 25 is provided with an exhaust pipe 44. One end of the exhaust pipe 44 is connected to the exhaust hole 31, and the other end is connected to the exhaust main pipe 3. The negative pressure exhaust design is adopted. The polluted airflow in the incubation chamber is discharged through the exhaust hole 31 and the exhaust pipe 44 into the exhaust main pipe 3. Combined with the positive pressure air intake, a stable unidirectional airflow circulation is formed to ensure continuous air replacement in the chamber.

[0042] Combined with appendix Figure 5 and attached Figure 6The heat exchange fin 26 is provided with an inlet ring pipe 28 at one end and a return ring pipe 27 at the other end. The hot water pipe in the heat exchange fin 26 is connected to the inlet ring pipe 28 and the return ring pipe 27 respectively. The inlet ring pipe 28 is connected to the hot water supply pipe 4, and the return ring pipe 27 is connected to the hot water return pipe 5.

[0043] The annular water distribution structure ensures uniform hot water flow across all heat exchange fins, guaranteeing consistent temperature throughout the fins and preventing uneven heating by airflow. This, in turn, ensures consistent temperature across the entire incubation chamber. Combined with appendix Figure 4 Appendix Figure 6 Appendix Figure 11 and attached Figure 12 The main chamber 6 is equipped with an atomizing water tank 21, and an atomizer 22 is installed at the bottom of the atomizing water tank 21. The bottom of the return water ring pipe 27 is connected to an atomizing water supply pipe 34, which extends to the top of the atomizing water tank 21 to supply water into the atomizing water tank 21. With the waste heat recovery energy-saving design, the hot water after heat exchange and cooling flows into the atomizing water tank 21 through the atomizing water supply pipe 34 as a humidification water source. The waste heat of the water body is used to improve the atomization efficiency, eliminating the need for additional heating of the humidification water, maximizing the use of heat energy and reducing operating costs.

[0044] Combined with appendix Figure 3 The main chamber 6 has a front cover plate 11 on the side near the incubation chamber 24 and a rear cover plate 19 on the side near the equipment chamber 25. The front cover plate 11 has a door 12. The front cover plate 11, the door 12 and the rear cover plate 19 together seal the main chamber 6. The equipment chamber 25 has an equipment chamber cover plate 20 at the end for sealing. The inner wall of the door 12 has a temperature and humidity transmitter 13. After the door 12 is closed, the temperature and humidity transmitter 13 monitors the temperature and humidity in the incubation chamber 24 in real time and transmits it to an external control computer or PLC or other control equipment. The external control equipment controls the opening and closing of the atomizer 22 and the hot water flow rate according to the data from the temperature and humidity transmitter 13.

[0045] Combined with appendix Figure 3 Appendix Figure 7 Appendix Figure 11 and attached Figure 12 The rear cover plate 19 is provided with an air inlet pipe 45, which connects the clean air main pipe 2 to the interior of the main chamber 6. The outer ring of the incubation tube 7 is fitted with guide plates 35 at both ends of the heat exchange fins 26. The guide plates 35 are provided with guide windows 36 that cooperate with the heat exchange fins 26. The remaining positions are sealed. The airflow in the main chamber 6 can only flow through the heat exchange fins 26 under the guidance of the guide plates 35 and the guide windows 36.

[0046] Directional airflow forced heat exchange, with sealed baffle 35 blocking airflow bypass, all clean air must pass through baffle 36 and heat exchange fins 26 to achieve full contact heat exchange between airflow and fins, improve circulation efficiency, and avoid uneven temperature and humidity caused by airflow short circuit.

[0047] Combined with appendix Figure 10 Appendix Figure 13 and attached Figure 14 The incubation chamber 24 is provided with a sliding cylinder 8 that slides close to the inner wall of the incubation chamber 24. The sliding cylinder 8 is provided with a guide rod 42. The partition plate 23 is provided with a guide hole 29 that matches the guide rod 42. The guide rod 42 extends into the equipment chamber 25. The end of the guide rod 42 is provided with a connecting ring 43. The equipment chamber 25 is provided with an electric cylinder 14. The free end of the electric cylinder 14 is connected to the connecting ring 43.

[0048] Combined with appendix Figure 12 and attached Figure 15 The electric cylinder 14 drives the sliding cylinder 8 to slide within the incubation chamber 24. This allows the sliding cylinder 8 to cover the grille 33, thus adjusting the flow cross-sectional area of ​​the humid and clean air entering the incubation chamber 24. The flow cross-sectional area can be linearly adjusted by regulating the displacement distance of the sliding cylinder 8, thereby regulating the clean air blowing flow rate. Simultaneously, the sliding cylinder 8 serves as a telescopic structure for removing the hatched chicks. The electric cylinder 14 and sliding cylinder 8 move along the inner wall of the incubation chamber. During incubation, the sliding cylinder 8 retracts into the chamber for sealed cultivation; when the hatched chicks are removed, the sliding cylinder 8 extends outside the chamber. This convenient and seamless operation avoids the need for manual entry into the chamber, which could disrupt the cultivation environment. Combined with appendix Figure 5 Appendix Figure 8 and attached Figure 9 The partition plate 23 is provided with a sleeve 32 extending into the incubation chamber 24. The sleeve 32 is slidably connected to a pull rod 9. The pull rod 9 is bent in the middle. Both sides of the bend of the pull rod 9 are provided with swing arms 37. The ends of the swing arms 37 are rotatably connected to a roller 10. The middle of the pull rod 9 is provided with a vertically sliding buckle 38 and a gate block 40. The middle of the pull rod 9 is provided with a vertical sliding groove 41. A hand-tightening screw 39 is rotatably provided on the buckle 38. The hand-tightening screw 39 passes through the sliding groove 41 and is threadedly connected to the gate block 40. The top of the buckle 38 abuts against the bottom of the swing arm 37.

[0049] Combined with appendix Figure 15 When it is time to put in eggs to be incubated, open the hatch 12 and manually pull out the lever 9. The roller 10 can be pulled out at the same time. Adjust the position of the sliding buckle 38 according to the size of the eggs so that the roller 10 can match the eggs. After the adjustment is completed, place the eggs on the roller 10, manually push the lever 9 into the incubation chamber 24 and close the hatch 12 to start incubation.

[0050] The stepless adjustment adaptable structure allows the sliding buckle 38 to slide up and down along the slide groove 41 by loosening the hand screw 39, and the push arm 37 to swing around the hinge point, thereby adjusting the support height of the roller 10. Locking the hand screw 39 can fix the position through the gate block 40, adapting to the stable lifting of poultry eggs of different diameters, solving the problem of poor adaptability of existing equipment, and has strong versatility.

[0051] In the specific implementation of the above structure, foam or silicone sleeves can be fitted on the outside of the idler roller 10 to prevent the eggs from being bumped or damaged.

[0052] Combined with appendix Figure 5 Appendix Figure 13 and attached Figure 14 The equipment compartment 25 is equipped with an egg-turning motor 15, which is powered by a gear 16. The partition plate 23 is provided with an annular groove 30, and a connecting bearing 46 is slidably provided in the annular groove 30. The connecting bearing 46 is rotatably connected to a gear 2 17 that meshes with the gear 1 16. A shaft 18 is provided on the gear 2 17 and extends into the incubation compartment 24. The roller 10 is sleeved on the shaft 18.

[0053] Referring to the attached diagram, the egg-turning motor 15 drives gear 16 to mesh with transmission gear 2 17. Gear 2 17 rotates along the annular groove 30 through the connecting bearing 46, synchronously driving the shaft 18 and the roller 10 to rotate at a uniform speed. The friction of the roller drives the eggs to turn slowly, ensuring that the eggs are heated evenly and preventing the embryos from sticking together. The annular groove centering design ensures that there is no shaking during the egg-turning process, and the operation is stable and low-noise.

[0054] The present invention and its embodiments have been described above. This description is not restrictive, and the actual structure is not limited thereto. In conclusion, if those skilled in the art, inspired by this description, design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the scope of protection of this invention.
