Description

Technical Field

[0001] This invention relates to the field of poultry incubation equipment technology, and more particularly to an egg-turning device for incubating eggs. Background Technology

[0002] In the egg incubation industry, turning the eggs is a crucial step in ensuring normal embryonic development. Proper egg turning prevents the embryo from sticking to the inner shell, promotes even heating of the embryo, and increases the hatching rate.

[0003] However, existing egg-turning devices have shortcomings. Traditional devices often use bolts to fix the egg frame and transmission structure, making disassembly and assembly cumbersome, especially in large-scale incubation scenarios where frequent egg replacement is labor-intensive and time-consuming. Furthermore, the fixed egg frame structure cannot accommodate eggs of different sizes, requiring replacement of the entire egg frame, increasing equipment costs. To address these issues, this invention proposes an egg-turning device for chicken egg incubation to overcome the deficiencies of existing technologies. Summary of the Invention

[0004] In order to overcome the shortcomings of existing egg-turning devices, such as low loading and unloading efficiency and poor versatility, the present invention provides an egg-turning device for egg incubation.

[0005] Technical Solution: An egg-turning device for egg incubation includes an outer shell, an insulation door, a main heating lamp, a geared motor, a mounting frame, a rotating rod, a rear rod, a front rod, a connecting rod, a front panel, side panels, a rear panel, an upper limit cover, a lower limit cover, and mounting components. The insulation door is hinged to the front end of the outer shell. Main heating lamps are symmetrically embedded at the upper and lower ends of the inner wall of the outer shell. The mounting frame is bolted inside the outer shell. A geared motor is fixed to the bottom of the mounting frame via a motor mount. The output shaft of the geared motor is coaxially fixed to the rotating rod and the connecting rod via a coupling. The two ends of the rotating rod are rotatably connected to the rear rod via bearings. The rod and the front rod, the rear rod and the front rod are rotatably connected by another rotating rod at the ends away from the reduction motor, forming a parallelogram linkage frame. The end of the connecting rod away from the reduction motor is connected to another parallelogram linkage frame. Multiple layers of egg frames are equidistantly arranged between the two parallelogram linkage frames. The egg frame is assembled from a front panel, a rear panel and two side panels. The upper and lower ends of the egg frame are respectively snapped with upper limit caps and lower limit caps. The front panel and the rear panel are equipped with mounting parts near the parallelogram linkage frame. The egg frame is detachably connected to the rear rod and the front rod through the mounting parts and the insertion ports of the front rod.

[0006] In addition, it is particularly preferred that the insulated door also includes a viewing window.

[0007] Furthermore, it is particularly preferred that the housing also includes pulleys, with four pulleys mounted on the bottom of the housing.

[0008] In addition, it is particularly preferred that a secondary heating lamp is also included, with the secondary heating lamp installed on the inner wall of the outer shell corresponding to each layer of egg frames, and the different light color modes corresponding to different stages of incubation.

[0009] Furthermore, it is particularly preferred that the mounting components include a telescopic sleeve, a spring, a plug rod, and a pull rod. The telescopic sleeve is fixedly connected to both the front and rear panels. The plug rod is slidably connected inside the telescopic sleeve. A spring is fixedly connected between the plug rod and the telescopic sleeve. A pull rod is fixedly connected to the side end of the plug rod. The plug rod is inserted into the rear and front rods through a socket.

[0010] Furthermore, it is particularly preferred that the inner sides of the front panel and the side panel have two sliding grooves for the sliding installation of the upper limit cover and the lower limit cover, respectively, the front panel and the side panel are fixedly connected, and the side panel has a slot for the rear panel to be inserted near the rear panel.

[0011] In addition, it is particularly preferred that the device also includes a controller, which is installed on the insulated door. The controller integrates temperature, humidity and carbon dioxide concentration sensors. The sensors monitor various parameters of the incubation environment in real time and display them on the screen.

[0012] In addition, it is particularly preferred that both the outer shell and the insulated door adopt a double-layer hollow structure, with the outer layer made of cold-rolled steel plate of appropriate thickness and the inner layer made of food-grade stainless steel plate, and a high-density polyurethane foam insulation layer filling the space between the two layers. Beneficial effects

[0013] 1. This invention, through the coordinated operation of a parallelogram linkage frame and a reduction motor, can precisely control the rotation angle and speed of the egg frame, ensuring that the eggs are evenly stressed and rotated smoothly during incubation. This effectively avoids the problem of the embryo sticking to the inner wall of the eggshell, significantly improving the survival rate and hatchability of the embryo. Compared to traditional devices, the eggs are heated more evenly, resulting in more stable embryo development.

[0014] 2. This invention uses a spring-loaded quick-connect assembly, which eliminates the traditional bolt connection method. Workers can install and disassemble the egg frame simply by pulling and releasing the lever, which greatly shortens the operation time and improves the efficiency of replacing hatching eggs. It is especially suitable for batch operations in large-scale hatcheries and reduces the intensity of manual labor.

[0015] 3. This invention utilizes a sliding upper and lower limit cover design, along with a slot-connected rear panel, to allow the egg frame to flexibly adapt to different sizes of poultry eggs. For example, when incubating chicken eggs, a limit cover with a smaller egg slot can be used, while when incubating duck eggs, a limit cover with a larger egg slot can be used. The replacement process is simple and quick, requiring no modification to the entire egg frame, thus enhancing the versatility and practicality of the device.

[0016] 4. The controller of this invention integrates multi-parameter sensors and an intelligent control module, enabling real-time monitoring and automatic control of the incubation environment. It eliminates the need for frequent manual inspections and adjustments, reducing errors caused by human operation and ensuring that parameters such as temperature, humidity, and CO2 concentration are maintained within suitable ranges. This provides a stable environment for embryo development and reduces the risk of hatching failure due to environmental fluctuations.

[0017] 5. The dual-color adjustable design of the secondary heating lamp of the present invention can not only assist in heating, but also intuitively distinguish the incubation stages of different egg frames through light color, which can facilitate staff to quickly identify and manage, and improve the efficiency and accuracy of incubation management.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0028] Example: An egg-turning device for incubating eggs, such as... Figures 1-8 As shown, the device includes an outer shell 1, an insulated door 2, a main heating lamp 4, a geared motor 6, a mounting bracket 7, a rotating rod 8, a rear rod 9, a front rod 10, a connecting rod 11, a front panel 12, a side panel 13, a rear panel 14, an upper limit cover 15, a lower limit cover 16, and mounting components. The outer shell 1 has a double-layer hollow structure, with the insulated door 2 hinged to its front end. The main heating lamps 4 are symmetrically embedded at the upper and lower ends of the inner wall of the outer shell 1. The mounting bracket 7 is bolted inside the outer shell 1. The geared motor 6 is fixed to the bottom of the mounting bracket 7 via a motor mount. The output shaft of the geared motor 6 is coaxially fixed to the rotating rod 8 and the connecting rod 11 via a coupling. The two ends of the rotating rod 8 are rotatably connected to the rear heating lamp 11 via bearings. Rod 9 and front rod 10, and the rear rod 9 and the front rod 10 are rotatably connected by another rotating rod 8 at the end away from the reduction motor 6, forming a parallelogram linkage frame. The end of the connecting rod 11 away from the reduction motor 6 is connected to another parallelogram linkage frame. Multiple layers of egg frames are equidistantly arranged between the two parallelogram linkage frames. The egg frame is assembled from the front panel 12, the rear panel 14 and two side panels 13. The upper and lower ends of the egg frame are respectively snapped with the upper limit cover 15 and the lower limit cover 16. The front panel 12 and the rear panel 14 are provided with mounting parts near the parallelogram linkage frame. The egg frame is detachably connected to the rear rod 9 and the front rod 10 through the mounting parts.

[0029] like Figure 1 As shown, a viewing window 201 is provided on the insulated door 2, providing staff with a convenient way to observe the status of the hatching eggs and the turning of the eggs in the egg rack without opening the insulated door 2. This design effectively reduces the fluctuations in temperature and humidity inside the outer shell 1 caused by frequent door opening, avoids interference from the external environment on the incubation environment, helps maintain stable incubation conditions, ensures normal embryo development, and also allows staff to keep abreast of the incubation progress, improving management efficiency.

[0030] like Figures 1-3 As shown, four casters 3 are installed at the bottom of the outer casing 1, allowing staff to easily move the device between different incubation sites and meet the needs of various scenarios. Whether adjusting the device's position to adapt to the site layout or performing cleaning and maintenance operations, the casters 3 significantly reduce the difficulty of handling and save labor costs.

[0031] like Figures 1-3As shown, secondary heating lamps 5 are installed on the inner wall of the outer shell 1 at each egg rack. Different light color modes correspond to different incubation stages, providing precise auxiliary heating to each egg rack to ensure even heating of the eggs. The light color also allows for intuitive differentiation of incubation time in different egg racks. Staff can quickly identify eggs at different stages, facilitating targeted management and operation, reducing identification time and errors, and improving the accuracy and efficiency of incubation management. Simultaneously, the auxiliary heating function further ensures the temperature stability of the incubation environment.

[0032] like Figure 7 As shown, the mounting components include a telescopic sleeve 17, a spring 18, a plug rod 19, and a pull rod 20. The telescopic sleeve 17 is fixedly connected to both the front panel 12 and the rear panel 14. The plug rod 19 is slidably connected inside the telescopic sleeve 17. A spring 18 is fixedly connected between the plug rod 19 and the telescopic sleeve 17. A pull rod 20 is fixedly connected to the side end of the plug rod 19. The plug rod 19 is inserted into the rear rod 9 and the front rod 10 through a socket. Pulling the pull rod 20 compresses the spring 18 and retracts the telescopic sleeve 17. After aligning with the socket, releasing the pull rod 20 allows the plug rod 19 to insert into the socket under the elastic force of the spring 18, completing the installation. Conversely, it can be quickly disassembled. This design requires no tools, is simple and convenient to operate, and significantly shortens the time for egg rack installation and replacement. It is especially suitable for batch operations in large-scale hatcheries, reducing manual labor intensity and improving work efficiency.

[0033] like Figures 5-8 As shown, the inner sides of the front panel 12 and the side panel 13 are provided with two sliding grooves 21 for the sliding installation of the upper limit cover 15 and the lower limit cover 16, respectively. The front panel 12 and the side panel 13 are fixedly connected. The side panel 13 has a slot 22 near the rear panel 14 for the rear panel 14 to be inserted. The design of the sliding grooves 21 on the inner sides of the front panel 12 and the side panel 13, as well as the slot 22 on the side panel 13, provides a flexible and convenient way to install the upper limit cover 15, the lower limit cover 16, and the rear panel 14. The sliding grooves 21 allow the upper limit cover 15 and the lower limit cover 16 to be easily slidably installed and replaced according to the size of the eggs, meeting the limiting requirements of different sized hatching eggs and enhancing the versatility of the egg carton. The slot 22 ensures that the rear panel 14 can be quickly inserted and fixed, facilitating the assembly and disassembly of the egg carton. The overall structural design improves the assembly efficiency and usage flexibility of the egg carton and reduces the limitations caused by the fixed structure.

[0034] like Figure 1As shown, the controller 23 installed on the insulated door 2, through integrated temperature, humidity, and carbon dioxide concentration sensors, can monitor various incubation environment parameters inside the shell in real time and accurately, and present them intuitively to the staff through the display screen on the controller 23. This design realizes intelligent monitoring of the incubation environment, allowing staff to understand environmental changes in a timely manner. When parameters deviate from the set range, they can quickly take adjustment measures to avoid the impact of environmental abnormalities on embryo development, reduce the frequency and error of manual inspections, improve the stability and controllability of the incubation environment, and ensure the hatching rate.

[0035] The outer shell 1 and the insulated door 2 adopt a double-layer hollow structure. The outer layer of cold-rolled steel plate ensures the structural strength and durability of the device, while the inner layer of food-grade stainless steel plate meets hygiene standards, preventing contamination of the hatching eggs and the incubation environment. The high-density polyurethane foam insulation layer filling the space between the two layers, with its extremely low thermal conductivity, effectively blocks heat exchange between the inside and outside, significantly reducing heat loss from the shell and lowering energy consumption. Simultaneously, this structure maintains a stable internal temperature, providing a constant and suitable temperature environment for egg incubation, which is beneficial for the normal growth and development of the embryo.

[0036] Egg rack installation: During operation, the worker pulls the lever 20 on the egg rack. The lever 20 moves the insert rod 19 into the telescopic sleeve 17. At this time, the spring 18 is compressed and stores elastic potential energy. After the insert rod 19 is fully retracted into the telescopic sleeve 17, the egg rack is moved to the parallelogram linkage frame, aligning the telescopic sleeve 17 with the sockets on the rear lever 9 and the front lever 10. Releasing the lever 20 releases the elastic potential energy of the spring 18, pushing the insert rod 19 to pop out and insert into the socket, thus firmly installing the egg rack on the parallelogram linkage frame. The entire process can be completed quickly by one person without the aid of tools.

[0037] Incubation Operation: After closing the insulation door 2, the controller 23 sets the required parameters for incubation, such as temperature, humidity, and egg-turning cycle. The main heating lamp 4 starts to provide basic heat, and the secondary heating lamp 5 switches to the corresponding light color according to the incubation stage to assist in heating, ensuring a uniform and stable internal temperature for the outer shell 1. The geared motor 6 starts according to the preset program. Its output shaft first rotates clockwise, driving the rotating rod 8 to rotate synchronously. The two ends of the rotating rod 8 push the rear rod 9 upward and pull the front rod 10 downward, respectively. Since the rear rod 9, the front rod 10, and the rotating rod 8 form a parallelogram linkage frame, the egg frame tilts forward at a certain angle in a stable posture. This tilt angle is maintained for a period of time to ensure even heating of the eggs. Then, the output shaft of the geared motor 6 rotates counterclockwise by the corresponding angle, driving the rotating rod 8 to move in the opposite direction, causing the rear rod 9 to descend and the front rod 10 to rise, and the egg frame to tilt backward by the same angle. This cycle repeats to achieve even turning of the eggs during incubation, avoiding local pressure on the embryo or adhesion to the eggshell.

[0038] Status Monitoring: Staff can observe the status of the eggs in the egg rack and the egg-turning process at any time through the viewing window 201 on the insulated door 2, without opening the insulated door 2, thus reducing environmental fluctuations. The controller 23 monitors the temperature, humidity, and CO2 concentration inside the outer shell 1 in real time through integrated sensors and displays them dynamically on the touch screen. When the temperature is detected to be lower than the set value, the controller 23 automatically increases the power of the main heating lamp 4 and the secondary heating lamp 5; when the temperature is too high, it reduces the power of the heating lamps; when the humidity is insufficient, it activates the built-in humidifier to increase the humidity; when the CO2 concentration exceeds the standard, it turns on the ventilation device (not shown) to exchange air, ensuring that the incubation environment is always in the optimal state.
