Description

Technical Field

[0001] This application relates to the field of artificial incubation technology, and in particular to a laboratory incubator and incubation method. Background Technology

[0002] Artificial incubation of hatching eggs is an important breeding technique widely used in agriculture and animal husbandry. Laboratory breeding of poultry typically requires incubating eggs manually; therefore, laboratory incubators must ensure a high hatching rate to avoid economic losses. Artificial incubation refers to creating a suitable environment for hatching eggs by mimicking the incubation process. Incubators can be used to automate the incubation process. An incubator generally includes a tray for holding the eggs, a hot air blower, and a humidifier. During incubation, the eggs need to be turned regularly to ensure normal embryonic development and prevent embryonic adhesion and death.

[0003] Current technologies typically involve manual egg turning or placing the eggs on rollers within a tray, with the rollers rotating to turn the eggs. However, the irregular shape of the eggs makes the trajectory of the eggs as they rotate unpredictable, potentially causing them to fall off the rollers or collide with each other, leading to egg breakage and affecting hatching rates. Therefore, improvements are needed. Summary of the Invention

[0004] To reduce shell damage and improve the hatching rate of hatching eggs, this application provides a laboratory incubator and incubation method.

[0005] Firstly, the laboratory incubator provided in this application adopts the following technical solution:

[0006] A laboratory incubator includes a housing with an angle adjustment assembly installed inside. The angle adjustment assembly includes a rotating support, a chain, and a drive mechanism. The rotating support is rotatably connected to the housing. An egg tray is disposed inside the housing and mounted on the rotating support. The chain is connected to the rotating support, and a workbench is installed inside the housing with the chain positioned on the workbench. The drive mechanism is mounted on the workbench to drive the chain to move. A performance component is provided inside the housing to regulate the environment within the housing. A ventilation component is provided on the housing to connect the interior of the housing with the outside air.

[0007] By adopting the above technical solution, when incubation is needed, the operator places the hatching eggs in the egg tray and then installs the tray onto the rotating support. When the eggs need to be turned, a drive mechanism moves the chain within the placement area, increasing or decreasing the length of one side of the chain in the incubation area, causing the rotating support to rotate. This creates an angle between the egg tray and the horizontal plane, causing the eggs in the tray to rotate relative to the chamber. During incubation, the operator adjusts the temperature and humidity inside the chamber using performance components, maintaining them within the suitable incubation range. When ventilation is needed, the operator controls the airflow between the inside and outside of the chamber using ventilation components. The angle adjustment component rotates the egg tray to achieve egg rotation. The eggs, placed in the egg slots, do not contact moving parts or collide with other eggs, reducing egg breakage during turning and improving the hatching rate.

[0008] Optionally, the rotating support includes a connecting plate, several tray supports, and a fixing plate; one end of each tray support has an opening, and the side plate of the tray support away from the opening is rotatably connected to the connecting plate, and the connecting plate is installed on the inner wall of the box away from the opening; several tray supports are arranged in parallel, the egg tray is placed on the tray support, and the chain is installed on the tray support; both ends of the fixing plate are respectively connected to two side plates of the tray support near the opening to reinforce the tray support.

[0009] Optionally, the chain includes a main chain and several branch chains. Both ends of the main chain pass through the workbench. The main chain spans two side plates of the pallet support near the opening. The main chain is driven by a drive unit. Several branch chains are installed at both ends of the main chain. One end of each branch chain is connected to the main chain, and the other end is connected to the side plate of the pallet support near the opening.

[0010] Optionally, the driving component includes a drive motor, a drive sprocket, and a driven sprocket. The drive motor is mounted on one side of the main chain on the workbench. The output end of the drive motor is connected to the drive sprocket, which is rotatably connected to the workbench and meshes with the main chain. The driven sprocket is rotatably connected to the workbench, and the driven sprocket and the drive sprocket are driven by the main chain.

[0011] Using the above technical solution, before incubation, operators place cleaned hatching eggs into suitable egg slots in the egg tray; the egg tray is then placed on a tray support and a fixing plate is installed. When egg turning is needed, the drive motor is started, and its output drives the drive sprocket to rotate, causing six branch chains on one side of the main chain to move towards the worktable; the drive sprocket and driven sprocket rotate synchronously to avoid direct contact between the chain and the worktable, thus preventing wear. The other six branch chains move away from the worktable, causing the tray support to rotate around the axis, with the three tray supports remaining parallel to each other, until the angle between the egg tray and the horizontal plane reaches 45° and stops. After a three-hour interval, the drive motor is started to rotate the drive sprocket in the opposite direction, causing the chain to rotate the tray support in the opposite direction until the egg tray is parallel to the horizontal plane and stops. This completes one egg turning cycle. The process of rotating the egg is safe, reducing the possibility of egg breakage due to direct contact with moving parts; the egg-turning process is fully automated, avoiding operator forgetfulness that could cause the embryo to stick to the shell, improving the hatching rate of hatching eggs and reducing losses caused by unhatched eggs.

[0012] Optionally, the performance components include a hot air blower, a humidifier, and an internal circulation device. The hot air blower is installed on the bottom wall of the workbench away from the opening of the chamber, the humidifier is installed on the bottom wall of the workbench near the opening of the chamber, and the internal circulation device is installed on the bottom wall of the workbench to circulate the air inside the chamber.

[0013] Optionally, the internal circulation component includes a fan and an air guide plate. The air guide plate is installed on the bottom wall of the workbench near the opening of the housing and is inclined toward the opening of the housing. The fan is installed on the bottom wall of the workbench and is located between the hot air blower and the air guide plate.

[0014] By adopting the above technical solution, when the temperature and / or humidity in the incubation area are lower than the set value, the hot air blower and / or humidifier are activated. The hot air blower blows hot air towards the opening of the chamber, and the fan between the hot air blower and the water storage box accelerates and guides the hot air towards the water storage box. The atomizer atomizes the water in the water storage box, and the fan between the water storage box and the air guide plate accelerates and guides the humid and hot air towards the opening of the chamber. The air guide plate guides the humid and hot air blown horizontally towards the opening of the chamber to a vertical direction from the workbench towards the bottom wall of the chamber, conducting heat and moisture to the rotating support, and finally returning to the hot air blower, forming an internal air circulation within the chamber. The internal circulation component ensures uniform temperature and humidity within the chamber, preventing hot air from accumulating at the top of the chamber, which would result in insufficient temperature conditions for incubation at the bottom of the chamber, thus improving the hatching rate of the eggs and reducing losses caused by unhatched eggs.

[0015] Optionally, the ventilation assembly is installed on the door panel at the opening of the enclosure. The ventilation assembly includes an adjustment plate, a mounting plate, and an adjustment knob. The door panel is a double-layered panel, and the mounting plate is installed between the two layers and is in contact with both surfaces. The mounting plate has a through groove along its length, and the adjustment plate is disposed within the through groove. The adjustment plate has a toothed groove. The adjustment knob includes a knob cap and a rotating gear. The rotating gear is installed between the two layers and is rotatably connected to the door panel. The rotating gear meshes with the adjustment plate through the toothed groove. The knob cap is rotatably connected to the door panel and is fixedly connected to the rotating gear, and rotates coaxially with the rotating gear. The door panel has ventilation holes, and the adjustment plate has adjustment holes that can communicate with the ventilation holes.

[0016] By adopting the above technical solution, when ventilation is needed in the incubation area, the operator rotates the nut to drive the rotating gear. The rotating gear meshes with the tooth groove, causing the adjusting plate to move horizontally until the adjusting hole aligns with the ventilation hole, allowing air outside the chamber to connect with air inside the chamber. The operator then rotates the nut in the opposite direction, causing the rotating gear to rotate in the opposite direction, moving the adjusting plate in the opposite horizontal direction until the ventilation hole is completely blocked by the plate surface between the adjusting holes on the adjusting plate, and the adjusting hole is also completely blocked by the plate surface between the ventilation holes on the door panel. The ventilation hole and adjusting hole are closed, sealing the incubation area of ​​the chamber and preventing communication with the outside. When oxygen is insufficient inside the chamber, oxygen is supplied through the ventilation hole. The internal circulation inside the chamber ensures fair ventilation and fresh air. After ventilation, the ventilation hole is closed, and the chamber is sealed to maintain the temperature and humidity inside. There is no need to open the door panel, which would cause a large loss of heat and moisture and waste resources.

[0017] Secondly, this application also discloses an incubation method using a laboratory incubator:

[0018] Preparation: Set the temperature and humidity inside the laboratory incubator according to the breed of eggs. Check whether the temperature and humidity inside the chamber have reached the set values. If there is a deviation, adjust until the set values ​​are reached.

[0019] Egg processing: First, the hatching eggs are candled for inspection. After the inspection is completed, the eggs are left to stand, cleaned and dried, and then placed in the egg tray.

[0020] Incubation: The egg tray containing the hatching eggs is installed onto the tray support, and the chamber is closed; during the incubation process, the performance components operate to regulate the temperature and humidity inside the chamber;

[0021] Egg flipping: The angle between the egg tray and the horizontal plane is adjusted by the angle adjustment component to achieve egg flipping;

[0022] Ventilation: The ventilation components control the closure of the enclosure or its connection to the outside air.

[0023] Hatching process: After hatching, the larvae are transferred to the bottom of the box and incubated after their feathers have dried.

[0024] Cleaning: Remove the fixing plate and take out the egg tray, clean all components inside the box and disinfect them in preparation for the next incubation.

[0025] By adopting the above technical solution, the hatching eggs are placed in appropriately sized egg trays, ensuring stable placement during the rotation of the egg tray and reducing egg breakage. Internal air circulation within the enclosure ensures uniform temperature and humidity, allowing the eggs to incubate under the set temperature and humidity conditions, thus improving the hatching rate and reducing losses due to unhatched eggs. The ventilation system opens when ventilation is needed and closes when not; the ventilation holes are small, eliminating the need to open the door for ventilation and preventing significant resource waste. Larvae are kept dry in the collection box, maintaining their body temperature and preventing death from sudden transfer to a new environment.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. When incubation is required, the operator places the hatching eggs in the egg tray and then installs the tray onto the rotating support. When the eggs need to be turned, a drive mechanism moves the chain within the placement area, increasing or decreasing the length of one side of the chain in the incubation area. This causes the rotating support to rotate, creating an angle between the egg tray and the horizontal plane, causing the eggs to rotate relative to the incubator. During incubation, the operator uses performance components to adjust the temperature and humidity inside the incubator, maintaining them within the suitable incubation range. When ventilation is needed, the operator uses ventilation components to control the airflow between the inside and outside of the incubator. Using an angle adjustment component to rotate the egg tray to achieve egg rotation reduces egg breakage during turning and improves the hatching rate.

[0028] 2. When egg turning is required, the output of the drive motor drives the active sprocket to rotate, causing the six branch chains on one side of the main chain to move closer to the work surface. The active and driven sprockets rotate synchronously, preventing direct contact between the chains and the worktable and thus avoiding wear. The other six branch chains move away from the worktable, causing the tray support to rotate around the axis until the egg tray forms an angle with the horizontal plane. After a three-hour interval, the drive motor is started to rotate the tray support in the opposite direction, returning the egg tray to its original position, completing one egg turning cycle. The egg rotation process is safe, reducing the possibility of egg breakage due to direct contact with moving parts; the fully automatic egg turning process avoids operator forgetfulness that could cause the embryo to stick to the shell, improving the hatching rate of hatching eggs and reducing losses due to unhatched eggs.

[0029] 3. When ventilation is needed in the incubation area, the operator rotates the nut to drive the rotating gear. The gear meshes with the toothed groove, moving the adjusting plate horizontally until the adjusting hole aligns with the ventilation hole, allowing air outside the chamber to connect with air inside. The operator then rotates the nut in the opposite direction, causing the rotating gear to rotate in the opposite direction, moving the adjusting plate horizontally until the ventilation hole is completely blocked by the plate surface between the adjusting holes on the adjusting plate, and the adjusting hole is also completely blocked by the plate surface between the ventilation holes on the door panel, closing both the ventilation hole and the adjusting hole. When oxygen is insufficient inside the chamber, oxygen is supplied through the ventilation hole. The internal circulation within the chamber ensures fair ventilation and fresh air. After ventilation, the ventilation hole is closed, and the chamber is sealed to maintain the temperature and humidity inside. Opening the door panel eliminates the need to open it, preventing significant heat and moisture loss and resource waste. Attached Figure Description

Detailed Implementation

[0036] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0037] This application discloses a laboratory incubator. (Refer to...) Figure 1 A laboratory incubator includes a housing 1, within which a workbench 8 is installed. The space between the workbench 8 and the top plate of the housing 1 forms a placement area, while the space between the workbench 8 and the bottom plate of the housing 1 forms an incubation area. A performance component 6 is installed within the incubation area, mounted on the bottom wall of the workbench 8, to regulate the environment within the housing 1. A rotating support 3 is installed within the incubation area, mounted on the side wall of the housing 1 away from the opening, and an egg tray 7 is mounted on the rotating support 3. A chain 4 is connected to the rotating support 3, positioned within the placement area and passing through the workbench 8 into the incubation area; both ends of the chain 4 are connected to the two ends of the rotating support 3. A drive unit 5 is installed within the placement area, mounted on the workbench 8, and drives the chain 4 to move.

[0038] A collection box 12 is also set up in the incubation area. The collection box 12 is placed below the rotating support 3, and the hatched eggs can be moved into the collection box 12. A door panel 11 is installed at the opening of the box 1. A ventilation component 9 is installed on the door panel 11. The ventilation component 9 allows the air inside the box 1 to circulate with the outside air to ensure sufficient oxygen for the embryos and hatched eggs in the later stage of incubation.

[0039] When incubation is needed, the operator places the hatching eggs in the egg tray 7, then installs the egg tray 7 onto the rotating support 3 and closes the door panel 11. At this time, the inside of the chamber 1 is not connected to the outside air. During incubation, the operator adjusts the temperature and humidity inside the chamber 1 using the performance component 6 to maintain them within the set range suitable for incubation. When the hatching eggs need to be turned, the drive component 5 drives the chain 4 in the placement area to move along the length of the chain 4, increasing or decreasing the length of one side of the chain 4 in the incubation area. This causes the rotating support 3 to rotate, causing the egg tray 7 to rotate and form an angle with the horizontal plane, causing the hatching eggs placed in the egg tray 7 to rotate relative to the chamber 1. When the chamber 1 needs ventilation, the operator controls the connection between the inside of the chamber 1 and the outside air using the ventilation component 9. After ventilation, the ventilation component 9 controls the connection between the inside of the chamber 1 and the outside air to be closed. When a hatching egg hatches, the operator places the collection box 12 under the rotating support 3 and transfers the hatchlings into the collection box 12.

[0040] Reference Figure 2The rotating support 3 includes a connecting plate 32, which is fixedly connected to the inner wall of the housing 1 away from the opening. Three pallet supports 31 are mounted on the connecting plate 32, arranged parallel vertically. The pallet supports 31 are rotatably connected to the connecting plate 32 via a pivot, allowing them to rotate around the pivot against the connecting plate 32. The pallet supports 31 are U-shaped, horizontally positioned with their openings close to the opening of the housing 1. The side plate of the pallet support 31 away from the opening is connected to the connecting plate 32, and a chain 4 is connected to the side plate of the U-shaped frame near the opening. A fixing plate 33 is installed at the opening of the pallet support 31, with both ends of the fixing plate 33 bolted to the bottom walls of the two side plates of the pallet support 31 near the opening.

[0041] Egg trays 7 are placed on tray supports 31. In this embodiment, two egg trays 7 are placed on each tray support 31. The egg tray 7 includes a tray 71, which has a porous structure. Several grid plates 72 are provided inside the tray 71. Several slots are provided on the grid plates 72. The grid plates 72 in the warp direction and the grid plates 72 in the weft direction are interlocked by the slots to form rectangular egg slots. Hatching eggs are placed in the egg slots.

[0042] Before incubation, the operator snaps together the grating plate 72 in the warp direction and the grating plate 72 in the weft direction according to the size of the hatching eggs and installs them into the tray 71. The cleaned hatching eggs are placed into the matching egg slots in the egg tray 7. The egg tray 7 is placed on the tray support 31, with the edge of the tray 71 resting on the side wall of the tray support 31. The fixing plate 33 is fixed to the opening of the tray support 31 with bolts, thus completing the placement of the hatching eggs. This allows the drive component 5 to drive the chain 4 to control the rotation of the tray support 31, thereby turning the eggs.

[0043] Reference Figure 3 and Figure 4 The driving component 5 includes a drive motor 51, which is fixedly mounted on the worktable 8. In this embodiment, the drive motor 51 is a double-headed motor, with a drive sprocket 52 connected to each of its two output ends. The drive sprockets 52 are rotatably connected to the worktable 8, and each drive sprocket 52 drives a chain 4. The chain 4 includes a main chain 41, which spans two side plates of the tray support 31 near the opening. The main chain 41 meshes with the peripheral wall of the drive sprocket 52. The output end of the drive motor 51 drives the drive sprocket 52 to rotate relative to the worktable 8, thereby moving the main chain 41 along its length. A driven sprocket 53 is also provided on the main chain 41, which is rotatably connected to the worktable 8. The peripheral wall of the driven sprocket 53 meshes with the main chain 41, and the drive sprockets 52 and driven sprockets 53 connected to each main chain 41 are driven by this main chain 41.

[0044] In this embodiment, the two main chains 41 are arranged in parallel. One main chain 41 is located away from the opening of the housing 1, and the other main chain 41 is located near the opening of the housing 1. The two ends of the main chain 41 extend from the driving sprocket 52 and driven sprocket 53 in the placement area, through the workbench 8, and into the incubation area. Several branch chains 42 are installed on both ends of the main chain 41 in the incubation area. In this embodiment, three branch chains 42 are installed on both ends of each main chain 41. One end of the branch chain 42 is hinged to the main chain 41, and the other end is bolted to the side plate of the tray support 31 near the opening. Two branch chains 42 are connected to each side plate of the tray support 31 near the opening. One branch chain 42 is located near the opening, and the other branch chain 42 is located away from the opening.

[0045] When the eggs need to be turned during incubation, the drive motor 51 is started. The output of the drive motor 51 drives the active sprocket 52 to rotate, which in turn drives the main chain 41 to move towards the driven sprocket 53. The length of the two main chains 41 extending into the incubation area from the active sprocket 52 decreases, which drives the six branch chains 42 on one side of the active sprocket 52 to move vertically towards the worktable 8. The active sprocket 52 and the driven sprocket 53 rotate synchronously, and the length of the two main chains 41 extending into the incubation area from the driven sprocket 53 increases synchronously, which drives the six branch chains 42 on one side of the driven sprocket 53 to move vertically away from the worktable 8. This causes the tray support 31 to rotate around the axis, and the three tray supports 31 remain parallel to each other until the angle between the egg tray 7 and the horizontal plane is 45°. Three hours later, drive motor 51 is started. The output of drive motor 51 drives the drive sprocket 52 to rotate in the opposite direction. Chain 4 drives tray support 31 to rotate in the opposite direction around the axis until the egg tray 7 is parallel to the horizontal plane. This completes one egg turning. The entire incubation process requires multiple egg turnings, while the performance component 6 controls the temperature and humidity inside the chamber 1.

[0046] Reference Figure 3 The performance component 6 includes a hot air blower 61, which is installed on the bottom wall of the workbench 8 near the connecting plate 32. The hot air blower 61 blows hot air towards the opening of the chamber 1. A humidifier 62 is installed between the hot air blower 61 and the opening of the chamber 1. The humidifier 62 includes a water storage box 621, which is fixedly installed on the workbench 8 in the incubation area. An atomizer 622 is installed on the water storage box 621 and is fixedly installed on the outer wall of the water storage box 621 away from the hot air blower 61. A water suction pipe connected to the atomizer 622 communicates with the inside of the water storage box 621 to atomize the water inside the water storage box 621. A water pump is also installed inside the water storage box 621. A water suction pipe connected to the water pump extends out of the water storage box 621 and the chamber 1 to draw water from an external water tank into the water storage box 621 to maintain the water level in the water storage box 621.

[0047] Performance component 6 also includes an internal circulation component 63, which includes a fan 631. In this embodiment, two fans 631 are fixedly installed on the workbench 8 in the incubation area. One fan 631 is installed between the hot air blower 61 and the water storage box 621, and the other fan 631 is installed between the water storage box 621 and the opening of the box 1. Both fans 631 guide air away from the opening of the box 1 towards the direction closer to the opening of the box 1. The internal circulation component 63 also includes an air guide plate 632. One end of the air guide plate 632 is fixed to the workbench 8 in the incubation area near the opening of the box 1 by bolts, and the other end is inclined away from the rotating support 3.

[0048] When the temperature and / or humidity in the incubation area are lower than the set value, the hot air blower 61 and / or humidifier 62 are activated. The hot air blower 61 blows hot air towards the opening of the chamber 1. The fan 631 between the hot air blower 61 and the water storage box 621 accelerates and guides the hot air towards the water storage box 621. The atomizer 622 atomizes the water in the water storage box 621. The fan 631 between the water storage box 621 and the air guide plate 632 accelerates and guides the hot and humid air towards the opening of the chamber 1. The air guide plate 632 guides the hot and humid air blown horizontally towards the opening of the chamber 1 to blow vertically from the workbench 8 towards the bottom wall of the chamber 1, conducting heat and moisture to the rotating bracket 3, and finally returning to the hot air blower 61, forming an internal air circulation within the chamber 1. During this process, the chamber 1 is closed, and the hatching eggs consume oxygen within the chamber 1. In the later stages of incubation, it is necessary to control the opening and closing of the ventilation component 9 for ventilation.

[0049] Reference Figure 5 The ventilation assembly 9 includes a mounting plate 92. The door panel 11 is a double-layer PC board. The mounting plate 92 is fixedly installed between the two PC boards by bolts and is in contact with the two PC boards. The mounting plate 92 has a through groove 921 in the length direction. An adjusting plate 91 is placed in the through groove 921. The adjusting plate 91 is in contact with the two inner walls in the width direction of the through groove 921. The length of the adjusting plate 91 is less than the length of the mounting plate 92. The adjusting plate 91 can move back and forth in the through groove 921 along the length direction of the mounting plate 92. The door panel 11 has ventilation holes 94. In this embodiment, five ventilation holes 94 are spaced apart on the door panel 11. The length of the ventilation holes 94 is less than the distance between the ventilation holes 94. The adjusting plate 91 has adjusting holes 95. In this embodiment, five adjusting holes 95 are correspondingly provided on the adjusting plate 91. The adjusting holes 95 are the same size as the ventilation holes 94. Each adjusting hole 95 is aligned and connected to the ventilation hole 94.

[0050] An adjustment knob 93 is provided on the door panel 11 to control the movement of the adjustment plate 91. The adjustment knob 93 includes a rotating gear 932, which is rotatably connected between two PC plates. A toothed groove 911 is provided at the contact point between the adjustment plate 91 and the through groove 921, and the rotating gear 932 meshes with the adjustment plate 91 through the toothed groove 911. A short shaft is connected to the rotating gear 932 and extends out of the door panel 11. A rotating cap 931 is fixedly connected to the short shaft, and the rotating cap 931 rotates synchronously with the rotating gear 932 on the outside of the door panel 11.

[0051] When ventilation is required in the incubation area, the operator rotates the cap 931, causing the rotating gear 932 to rotate. The rotating gear 932 meshes with the tooth groove 911, causing the adjusting plate 91 to move horizontally until the adjusting hole 95 aligns with the ventilation hole 94, thus connecting the air outside the chamber 1 with the air inside the chamber 1. The operator then rotates the cap 931 in the opposite direction, causing the rotating gear 932 to rotate in the opposite direction, thus moving the adjusting plate 91 in the opposite horizontal direction until the ventilation hole 94 is completely blocked by the plate surface between the adjusting holes 95 on the adjusting plate 91, and the adjusting hole 95 is also completely blocked by the plate surface between the ventilation holes 94 on the door panel 11. The ventilation hole 94 and the adjusting hole 95 are closed, and the incubation area of ​​the chamber 1 is sealed.

[0052] The implementation principle of a laboratory incubator according to an embodiment of this application is as follows: When incubation is required, the operator interlocks the grid plates 72 and installs them into the tray 71 to form egg slots. The hatching eggs are placed in the appropriate egg slots within the egg tray 7 according to their size. The egg tray 7 is then installed onto the tray support 31, and a fixing plate 33 is installed. The door 11 and ventilation assembly 9 are closed, at which point the interior of the chamber 1 is not connected to the outside air. During incubation, the temperature is adjusted by a hot air blower 61, the humidity is adjusted by a humidifier 62, and the temperature and humidity inside the chamber are evenly distributed by an internal circulation component 63. When turning the eggs is required, the drive motor 51 is started. The drive motor 51 moves the main chain 41, causing the branch chain 42 to rise or fall, and rotating the tray support 31, so that the egg tray 7 forms an angle with the horizontal plane, causing the hatching eggs placed in the egg tray 7 to rotate relative to the chamber 1. When ventilation is needed in chamber 1, the operator rotates the screw cap 931, causing the rotating gear 932 to rotate and the adjusting plate 91 to move until the adjusting hole 95 aligns with the ventilation hole 94, thus connecting the inside of chamber 1 with the outside air. The operator then rotates the screw cap 931 in the opposite direction, causing the adjusting plate 91 to move in the opposite direction until the ventilation hole 94 and the adjusting hole 95 are closed, sealing the incubation area of ​​chamber 1. When an egg hatches, the operator transfers the hatchling to the collection box 12 below the rotating support 3, where the hatchling's feathers dry before incubation is complete.

[0053] This application also discloses an incubation method using the laboratory incubator. The incubation method using the laboratory incubator includes the following steps:

[0054] Preparation: Set the temperature in the laboratory incubator to 37.8 degrees Celsius and the humidity to 60% according to the breed of hatching eggs. Start the hot air blower 61 and the humidifier 62. Check the temperature and humidity inside chamber 1. If there is a deviation, adjust it until the temperature and humidity readings reach the set values ​​before incubating the eggs. Cut the grid plate 72 according to the size of the tray 71. Assemble the grid plate 72 according to the size of the hatching eggs. Snap the grid plates 72 in the warp and weft directions into the tray 71 to form an egg trough that fits the size of the hatching eggs. Sterilize the egg tray 7 after assembly.

[0055] Egg processing: First, candling the eggs to check if they are fertilized. After the eggs have been checked, place them with the larger end facing up for more than 12 hours. Clean the eggs with warm water at 38 degrees Celsius and let them dry. Place them into the appropriate egg slots in the egg tray 7 according to their size.

[0056] Incubation: The egg tray 7 containing the hatching eggs is installed on the tray support 31. The two ends of the fixing plate 33 are fixedly connected to the two ends of the opening of the tray support 31 with bolts. The door panel 11 is closed to close the box body 1. At this time, the ventilation hole 94 on the door panel 11 is blocked by the adjustment plate 91 and is in a closed state. During the incubation process, the hot air blower 61 is controlled to blow hot air when the temperature inside the box body 1 is lower than 37.8 degrees Celsius, and the humidifier 62 is controlled to atomize when the air humidity inside the box body 1 is lower than 60%. The fan 631 between the hot air blower 61 and the humidifier 62 accelerates and guides the hot air towards the direction of the humidifier 62. The fan 631 between the humidifier 62 and the air guide plate 632 accelerates and guides the hot and humid air towards the opening of the box body 1. The air guide plate 632 guides the hot and humid air blown horizontally towards the door panel 11 to blow vertically from the workbench 8 towards the bottom wall of the box body 1, forming an internal air circulation inside the box body 1 and uniformly distributing the temperature and humidity inside the box body 1.

[0057] Egg Turning: Start the drive motor 51. The output of the drive motor 51 drives the active sprocket 52 to rotate, and the driven sprocket 53 rotates synchronously. The length of the two main chains 41 extending into the incubation area from the active sprocket 52 decreases, causing the six branch chains 42 on one side of the active sprocket 52 to move vertically towards the worktable 8. At the same time, the length of the two main chains 41 extending into the incubation area from the driven sprocket 53 increases synchronously, causing the six branch chains 42 on one side of the driven sprocket 53 to move vertically away from the worktable 8. This causes the tray support 31 to rotate around the axis, with the three tray supports 31 remaining parallel to each other until the angle between the egg tray 7 and the horizontal plane is 45°. After a three-hour interval, start the drive motor 51. The output of the drive motor 51 drives the active sprocket 52 to rotate in the opposite direction, and the chain 4 drives the tray support 31 to rotate in the opposite direction until the egg tray 7 is parallel to the horizontal plane. After a 3-hour interval, start the drive motor 51 to rotate the egg tray 7 to an angle of 135° with the horizontal plane. After another 3-hour interval, start the drive motor 51 again to rotate the egg tray 7 to be parallel with the horizontal plane. The drive component 5 drives the rotating bracket 3 through the chain 4 to complete one flip. The eggs can be flipped twice a day. Repeat the above steps until the 18th day.

[0058] Ventilation: The operator rotates the cap 931, causing the rotating gear 932 to rotate. The rotating gear 932 meshes with the tooth groove 911, causing the adjusting plate 91 to move horizontally until the adjusting hole 95 aligns with the ventilation hole 94, thus connecting the air outside the chamber 1 with the air inside the chamber. After maintaining this position for five minutes, the operator rotates the cap 931 in the opposite direction, causing the adjusting plate 91 to move horizontally in the opposite direction until the ventilation hole 94 is completely blocked by the adjusting plate 91. The ventilation hole 94 is then closed, and the incubation area of ​​the chamber 1 is sealed. Starting from day 15, the above steps are repeated every 8 hours.

[0059] Hatching process: When the eggs begin to hatch, place the collection box 12 under the rotating support 3 inside the box 1; transfer the hatched larvae to the collection box 12, and complete the incubation after the larvae's feathers have dried.

[0060] Cleaning work: Turn off the power to the box 1, remove the collection box 12 at the bottom of the box 1 that holds the larvae, loosen the bolts to remove the fixing plate 33, remove the egg tray 7 on the tray support 31, clean all the internal parts of the box 1 and disinfect them; remove the grid plate 72 installed in the tray 71, clean the tray 71 and the grid plate 72 and disinfect them.

[0061] The implementation principle of an incubation method using this laboratory incubator according to an embodiment of this application is as follows: The temperature and humidity inside the laboratory incubator are set according to the type of hatching eggs; the hot air blower 61 and humidifier 62 are started; after checking and adjusting until the measured values ​​of the thermometer and hygrometer reach the set values, the grid plate 72 is assembled according to the size of the hatching eggs and installed in the tray 71; after the eggs have been candled and inspected, they are left to stand, cleaned, and placed in the appropriately sized egg slots in the egg tray 7; the egg tray 7 is then installed on the tray support 31, and after installing the fixing plate, the door panel 11 is closed to seal the chamber 1. At this time, the ventilation holes 94 and adjustment holes 95 on the door panel 11 are closed. During the incubation process, the hot air blower 61, humidifier 62, and fan 631 are controlled to guide the hot and humid air to the air guide plate 632, which guides the hot and humid air from the horizontal direction to the vertical direction, forming an internal air circulation within the chamber 1.

[0062] The drive motor 51 is started at regular intervals, driving the chain 4 to rotate the tray support 31 until the angle between the egg tray 7 and the horizontal plane is 45°. After a three-hour interval, the drive motor 51 is started again, driving the tray support 31 to rotate in the opposite direction until the egg tray 7 is parallel to the horizontal plane. After another three-hour interval, the drive motor 51 is started again to rotate the egg tray 7 to an angle of 135° with the horizontal plane, and after another three-hour interval, the drive motor 51 is started again to rotate the egg tray 7 to be parallel to the horizontal plane. The above steps are repeated for the first 18 days of incubation. Starting from the 15th day, the operator rotates the screw cap 931 at regular intervals to align the adjustment hole 95 with the ventilation hole 94, allowing the air outside the chamber 1 to communicate with the air inside the chamber 1. After holding this position for five minutes, the operator rotates the screw cap 931 in the opposite direction until the ventilation hole 94 and the adjustment hole 95 are closed, sealing the incubation area of ​​the chamber 1. The above steps are repeated every 8 hours.

[0063] When the hatching eggs begin to hatch, transfer the hatchlings to the collection box 12 under the rotating support 3. After the hatchlings' feathers have dried, the incubation is complete. Turn off the power to the box 1, remove the collection box 12 at the bottom of the box 1 that holds the hatchlings, loosen the bolts to remove the fixing plate 33, remove the egg tray 7, remove the grid plate 72 installed in the tray 71, clean all the parts inside the box 1 and disinfect them.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
