[0002] Existing incubation equipment mainly consists of an incubation chamber and an egg-turning rack. Heating elements are installed in the incubation chamber to maintain a set temperature. However, the heating elements are located on one side of the egg-turning rack, their position is fixed, and the distance between them is relatively short. The passage between the heating elements and the egg-turning rack is narrow, hindering operators from entering and exiting the incubation chamber to move the egg-turning rack, and also affecting maintenance work. If the heating elements are too hot, operators could easily be burned when entering or exiting the incubation chamber. Summary of the Invention

[0026] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and to facilitate its implementation.

[0027] It should be noted that in the following embodiments, the terms "first," "second," and "third" do not represent an absolute distinction in structure and / or function, nor do they represent the order of execution; they are merely for the convenience of description.

[0028] like Figure 1 and Figure 2As shown, the present invention provides an incubation device, including an incubation chamber 1, an egg-turning rack 2, a heating tube 3 disposed in the incubation chamber 1, a first adjustment device disposed in the incubation chamber 1 for adjusting the height position of the heating tube 3, and a second adjustment device for controlling the heating tube 3 to switch between a raised state and a lowered state. The second adjustment device is connected to the first adjustment device, and the first adjustment device controls the heating tube 3 to switch between a working position and a storage position.

[0029] Specifically, such as Figure 1 and Figure 2 As shown, the incubation chamber 1 is equipped with a humidifier 30 and a ventilation fan 6. The humidifier 30 is used to maintain a certain humidity level in the incubation chamber 1. The ventilation fan 6 is rotatable and is used to agitate the air in the incubation chamber 1. The rotation center line of the ventilation fan 6 is parallel to a first direction, which is horizontal. The heating tube 3, the humidifier 30, and the ventilation fan 6 are located on the same side of the egg-turning rack 2, and there is a certain distance between them and the egg-turning rack 2. The heating tube 3 is used to maintain a certain temperature in the incubation chamber 1, making the temperature environment in the incubation chamber 1 suitable for the incubation of eggs. Multiple heating tubes 3 are provided. In the working state, the heating tubes 3 are horizontal. When the heating tubes 3 are in the working position, they are placed horizontally on one side of the egg-turning rack 2, and the distance between the heating tubes 3 and the egg-turning rack 2 is at its minimum. The heating tubes 3 in the working position are closer to the egg-turning rack 2. The length direction of the heating tube 3 is parallel to a second direction, which is horizontal and perpendicular to the first direction.

[0030] like Figure 2 and Figure 3As shown, the first adjustment device is installed on the first side wall of the incubation chamber 1. The first adjustment device includes a first motor 4 and a first transmission mechanism connected to the first motor 4. The first transmission mechanism includes a first lead screw 5, a first nut cooperating with the first lead screw 5, and a first mounting base 7 connected to the first nut. The second adjustment device is installed on the first mounting base 7. The first motor 4 is fixedly installed on the first side wall of the incubation chamber 1, and the first lead screw 5 is vertically installed on the first side wall of the incubation chamber 1. The first nut and the first lead screw 5 form a helical transmission pair, and the first mounting base 7 is fixedly connected to the first nut. After the first motor 4 operates, it drives the second adjustment device and its heating tube 3 to move vertically through the first transmission mechanism, thereby adjusting the height of the heating tube 3 and controlling the switching between the working position and the storage position of the heating tube 3. The first transmission mechanism used is a lead screw and nut mechanism, which has a self-locking function, ensuring that the heating tube 3 can be stably maintained in the working position or the storage position, resulting in higher reliability. The height of the storage position is greater than the height of the working position. The storage position is close to the top wall of the incubator, which is located above the first side wall and the storage position. The height of the heating tube 3 in the storage position is relatively high, and the distance between the heating tube 3 and the egg-turning rack 2 is at its maximum. This makes the space on one side of the egg-turning rack 2 where the heating tube 3 is located larger, providing operators with more operating space when moving the egg-turning rack 2 or performing other tasks, such as maintenance or adding water to the humidifier 30. This facilitates the operation of the operators or maintenance personnel without obstruction. The position of the heating tube 3, close to the upper side wall of the incubator 1, avoids the high temperature of the heating tube 3 from burning the operators or maintenance personnel, thus improving work safety.

[0031] like Figure 3 and Figure 4As shown, the second adjustment device includes a second motor 8, a second transmission mechanism 10 connected to the second motor 8, and a second mounting base 9 connected to the second transmission mechanism 10 and rotatably mounted. The second transmission mechanism 10 converts the rotational motion of the second motor 8 into the rotational motion of the second mounting base 9. The heating tube 3 is mounted on the second mounting base 9, and the second mounting base 9 drives the heating tube 3 to rotate synchronously. In this embodiment, the second transmission mechanism 10 is a worm gear mechanism. The second transmission mechanism 10 and the second motor 8 are mounted on the first mounting base 7. The process of the heating tube 3 switching from a lowered state to a raised state is the process of the heating tube 3 rotating upward from a horizontal state. The second motor 8 is fixedly mounted on the first mounting base 7, and the second mounting base 9 is rotatably mounted on the first mounting base 7. The worm of the second transmission mechanism 10 is fixedly connected to the output end of the second motor 8, the worm wheel of the second transmission mechanism 10 is fixedly connected to the second mounting base 9, one end of the heating tube 3 is fixedly connected to the second mounting base 9, and the rotation center line of the second mounting base 9 (i.e., the axis of the worm wheel) is parallel to the first direction. After the second motor 8 starts running, it drives the second mounting base 9 to rotate through the second transmission mechanism 10. The second mounting base 9 drives the heating tube 3 to rotate synchronously, so that the heating tube 3 switches between the raised and lowered states. The second transmission mechanism 10 is a worm gear mechanism, which has a self-locking function, ensuring that the heating tube 3 can be stably kept in the lowered or raised state, thus improving reliability.

[0032] like Figure 2 and Figure 4 As shown, when heating tube 3 is in the lowered state, its length direction is parallel to the second direction; when heating tube 3 is in the raised state, its length direction is vertical; when heating tube 3 is switched to the working position, it switches from the raised state to the lowered state. At this time, heating tube 3 can generate heat by being energized to heat the air in the incubation chamber 1, and the distance between the second end of heating tube 3 and the first side wall of the incubation chamber 1 is at its maximum. When the first motor 4 operates, driving the first transmission mechanism to operate, and switching heating tube 3 from the working position to the storage position, the second motor 8 operates, driving the second transmission mechanism 10 to operate, and the second mounting base 9 drives heating tube 3 to rotate upward, switching heating tube 3 from the lowered state to the raised state. At this time, the distance between the second end of heating tube 3 and the first side wall of the incubation chamber 1 is at its minimum, heating tube 3 is vertical and close to the first side wall, and heating tube 3 is approximately at the same height as the top of the egg-turning rack 2. At this time, heating tube 3 does not need to operate. The first end and the second end of the heating tube 3 are opposite ends along the length of the heating tube 3, and the first end of the heating tube 3 is fixedly connected to the second mounting base 9.

[0033] like Figure 2As shown, multiple heating tubes 3 are provided, and correspondingly multiple first and second adjusting devices are also provided, with the number of first and second adjusting devices being the same as the number of heating tubes 3. Each heating tube 3 is respectively set on a second adjusting device, and each second adjusting device is respectively set on a first adjusting device. There are two first side walls of the incubation chamber 1, and the two first side walls are on the same straight line parallel to the second direction. The same number of first adjusting devices are provided on each first side wall. All the first adjusting devices on the same first side wall are on the same straight line parallel to the first direction. The lengths of the first lead screws 5 of the first adjusting devices on the same first side wall are different, which can control the heating tubes 3 to be at different working heights, which is beneficial for reasonable control of the temperature in the incubation chamber 1. The humidifying device 30 and the ventilation fan 6 are located between the two first side walls, and the egg turning rack 2 is also located between the two first side walls. One of the first side walls has a doorway for the egg turning rack 2 and personnel to enter and exit.

[0034] like Figure 3 and Figure 5 As shown, the first motor 4 is connected to the first lead screw 5 via a gear transmission mechanism. This gear transmission mechanism includes a first driving gear 13, a first driven gear 14 meshing with the first driving gear 13, and a connecting assembly connected to the first driven gear 14. The connecting assembly includes a first connecting member 11 connected to the first driven gear 14, a second connecting member 12 connected to the first lead screw 5, and a first fastener threadedly connected to both the first connecting member 11 and the second connecting member 12. The first connecting member 11 and the second connecting member 12 are detachably connected. The first driving gear 13 is mounted on the output end of the first motor 4, the first driven gear 14 is fixedly connected to the first connecting member 11, and the second connecting member 12 is mounted on the upper end of the first lead screw 5.

[0035] like Figure 5As shown, the first connector 11 has a first mounting hole and a first semi-threaded hole 15, and the second connector 12 has a second mounting hole 16 and a second semi-threaded hole 17. The first mounting hole is a conical hole, and the outer surface of the second connector 12 is a conical surface. The first semi-threaded hole 15 and the second semi-threaded hole 17 are aligned. The first fastener is inserted into the aligned first semi-threaded hole 15 and the second semi-threaded hole 17 to achieve a threaded connection with the first connector 11 and the second connector 12. Both the first connector 11 and the second connector 12 are annular structures. The first mounting hole is the center hole of the first connector 11, and the second mounting hole 16 is the center hole of the second connector 12. The diameter of the first mounting hole is the same as the diameter of the outer surface of the second connector 12, and the taper of the first mounting hole and the outer surface of the second connector 12 are the same. The first semi-threaded hole 15 is located on the inner conical surface of the first connector 11, and the second semi-threaded hole 17 is located on the outer surface of the second connector 12. The arc of both the first semi-threaded hole 15 and the second semi-threaded hole 17 is 180 degrees. After the first connector 11 and the second connector 12 are assembled together, the inner circular surface of the first connector 11 fits against the outer circular surface of the second connector 12. The first semi-threaded hole 15 and the second semi-threaded hole 17 are aligned and, after being joined together, form a complete circular internal threaded hole. Then, the first fastener is screwed into the aligned first semi-threaded hole 15 and the second semi-threaded hole 17, which can fix the first connector 11 and the second connector 12 together, so that the first driven gear 14 can drive the first lead screw 5 to rotate synchronously through the connecting assembly.

[0036] like Figure 5 As shown, a slit 32 is provided on the second connector 12, which cuts the second connector 12 at a certain position in the circumferential direction. The slit 32 also forms an opening on both the inner and outer circular surfaces of the second connector 12 in the circumferential direction, and the opening of the slit 32 is relatively small. A plurality of first semi-threaded holes 15 are provided on the first connector 11, and all the first semi-threaded holes 15 are arranged sequentially along the circumference of the first connector 11. A plurality of second semi-threaded holes 17 are provided on the second connector 12, and all the second semi-threaded holes 17 are arranged sequentially along the circumferential direction of the second connector 12. The number of second semi-threaded holes 17 is the same as the number of first semi-threaded holes 15. The slit 32 is located between two adjacent second semi-threaded holes 17 in the circumferential direction. When maintenance work is required and the first adjusting device needs to be disassembled, the first fastener can be unscrewed from the first semi-threaded hole 15 and the second semi-threaded hole 17, and the first connecting piece 11 and the second connecting piece 12 can be separated. The first connecting piece 11 and the gear can be easily disassembled. Since the second connecting piece 12 is provided with a slit 32, the second connecting piece 12 can expand. Therefore, the second connecting piece 12 can also be easily removed from the first lead screw 5. This structure can improve disassembly efficiency and facilitate maintenance work without affecting power transmission. Moreover, it is not easy to damage related components during disassembly and assembly.

[0037] like Figure 5 As shown, the first connector 11 has four first semi-threaded holes 15, and the second connector 12 has four second semi-threaded holes 17. The second connector 12 is connected to the first lead screw 5 by a key, and a keyway is provided on the inner circular surface of the second connector 12.

[0038] like Figure 6 As shown, a temperature sensor 18 is installed inside the incubation chamber 1. The temperature sensor 18 is used to detect the air temperature inside the incubation chamber 1. The temperature sensor 18 is mounted on a mounting device, and its height is adjustable. The mounting device includes a first bracket 19 and a second bracket 20. The first bracket 19 is fixedly connected to the top wall of the incubation chamber 1. The temperature sensor 18 is fixedly mounted on the second bracket 20. The second bracket 20 is mounted on the first bracket 19 by a second fastener 21. The first bracket 19 has an adjustment hole for inserting the second fastener 21. The adjustment hole is a slotted hole with its length direction vertical. The second fastener 21 is a bolt, and the length of the adjustment hole is greater than the diameter of the second fastener 21. Tightening the second fastener 21 fixes the second bracket 20 to the first bracket 19, thereby fixing the height of the temperature sensor 18. During installation, inserting the second fastener 21 into different positions along the length direction of the adjustment hole allows for adjustment of the height of the second bracket 20, which in turn allows for adjustment of the height of the temperature sensor 18. This structure facilitates adjustment of the temperature sensor 18 during installation, is simple in structure, and easy to operate.

[0039] like Figure 1 and Figure 7As shown, the egg-turning rack 2 includes a frame 22, a bracket 23 rotatably connected to the frame 22, a tray 24 placed on the bracket 23 for holding hatching eggs, a movable frame 25 connected to the bracket 23 for rotating the bracket 23, and an egg-turning actuator connected to the movable frame 25 for controlling the vertical movement of the movable frame 25. The bracket 23 is arranged in two rows, and the movable frame 25 is located between the two rows of brackets 23. The upper surface of the tray 24 has multiple slots for placing hatching eggs. Multiple trays 24 are arranged on the bracket 23, and all trays 24 on the bracket 23 are arranged vertically and equidistantly. One end of the bracket 23 is rotatably connected to the frame 22, and the other end of the bracket 23 is rotatably connected to the movable frame 25. After the egg-turning rack 2 is placed in the incubation chamber 1, the length direction of the rack 22 is parallel to the second direction, the rotation center line of the bracket 23 is parallel to the second direction, and the length directions of the bracket 23 and the tray 24 are also parallel to the second direction. The two rows of brackets 23 are on the same straight line parallel to the first direction. After the egg-turning actuator is activated, it drives the movable rack 25 to move in a straight line in the vertical direction. The movable rack 25 drives the bracket 23 to rotate and controls the bracket 23 to rotate up and down within a set angle range, so that the bracket 23 switches between a horizontal state and an inclined state. The bracket 23 drives the tray 24 to rotate up and down synchronously to realize the egg-turning action.

[0040] like Figure 7As shown, the egg-turning mechanism includes a rotatable swing arm 26, a connecting rod 27 rotatably connected to the swing arm 26, a turntable 28 rotatably connected to the connecting rod 27, and a drive mechanism for driving the turntable 28 to rotate. A pin 29 is provided at the lower end of the movable frame 25. A groove is provided on the swing arm 26 for inserting the pin 29, the length of which is greater than the diameter of the pin 29. The drive mechanism mainly includes a third motor and a third transmission mechanism. The third motor is fixedly installed inside the incubation chamber 1. One end of the third transmission mechanism is connected to the output end of the third motor, and the other end is connected to the turntable 28. After the third motor operates, it drives the turntable 28 to rotate through the third transmission mechanism. The rotation center line of the turntable 28 is parallel to the second direction, and the turntable 28 is rotatably mounted on the bottom plate of the incubation chamber 1. One end of the connecting rod 27 is rotatably connected to the turntable 28, and the other end of the connecting rod 27 is rotatably connected to one end of the swing rod 26. The other end of the swing rod 26 is rotatably connected to the bottom plate of the incubation chamber 1. The rotatable connection point between the connecting rod 27 and the turntable 28 is at a certain distance from the rotation center line of the turntable 28. The groove is a recess extending along the length of the swing rod 26 and is located between the two ends of the swing rod 26 along its length. The pin 29 is cylindrical, and its diameter is smaller than the length of the groove and the same as the width of the groove. When the turntable 28 rotates, the connecting rod 27 drives the swing rod 26 to swing up and down, and the swing rod 26 to reciprocate. The rotation center line of the swing rod 26 is parallel to the second direction. During the reciprocating motion of the swing rod 26, the pin 29 slides along the groove. The swing rod 26 drives the movable frame 25 to reciprocate linearly in the vertical direction through the pin 29. The movable frame 25 drives the bracket 23 to reciprocate.

[0041] The egg-turning mechanism described above has good operational stability and generates little impact during operation, making the rotation of the tray 24 by the bracket 23 more stable and helping to improve the hatching effect of the eggs. When the egg-turning rack is removed from the incubation chamber, the pin 29 is pulled out from the groove provided on the swing rod 26.

[0042] like Figures 7 to 9As shown, the frame 22 is equipped with an anti-collision device and an anti-rotation device, which limits the movable frame 25 in the vertical direction, keeping the movable frame 25 relatively fixed to the frame 22. When egg-turning is not required, the anti-rotation device locks the movable frame 25, keeping it fixed in the vertical direction and preventing it from moving vertically. Consequently, the bracket 23 cannot rotate, and the bracket 23 and its tray 24 remain horizontal. When egg-turning is required, the anti-rotation device releases the movable frame 25, unlocking it and allowing the movable frame 25 to move vertically. The anti-rotation device includes a guide plate 37, an anti-rotation pin 35 movably mounted on the guide plate 37, a suction plate 36 connected to the anti-rotation pin 35, an elastic element 34 applying an elastic force to the suction plate 36, and a baffle 33 mounted on the guide plate 37. The elastic element 34 is sandwiched between the baffle 33 and the suction plate 36. The guide plate 37 is fixedly mounted on the frame 22. The guide plate 37 has a guide hole through which the anti-rotation pin 35 passes. The guide plate 37 guides the anti-rotation pin 35. The direction of movement of the anti-rotation pin 35 is parallel to the length direction of the frame 22. The shape of the guide hole matches the shape of the anti-rotation pin 35. The anti-rotation pin 35 is a cylinder, and the guide hole is a circular hole. The diameter of the guide hole is approximately equal to the diameter of the anti-rotation pin 35. The axis of the anti-rotation pin 35 is parallel to the length direction of the frame 22. The movable frame 25 is provided with a limiting hole for the anti-rotation pin 35 to be inserted. The shape of the limiting hole matches the shape of the anti-rotation pin 35, and the limiting hole is also a circular hole. The diameter of the limiting hole is approximately equal to the diameter of the anti-rotation pin 35, and the axis of the limiting hole is parallel to the length direction of the frame 22. The suction plate 36 is fixedly connected to one end of the anti-rotation pin 35, and the other end of the anti-rotation pin 35 is used to insert into the limiting hole on the movable frame 25. The guide plate 37 is located between the suction plate 36 and the movable frame 25. The size of the suction plate 36 is larger than the diameter of the guide hole on the guide plate 37, and the suction plate 36 can limit the depth of the anti-rotation pin 35 inserted into the limiting hole. The baffle 33 and the suction plate 36 are located on the same side of the guide plate 37, and the suction plate 36 is located in the middle of the two baffles 33. The baffle 33 has an L-shaped structure. One end of the baffle 33 is fixedly connected to the guide plate 37. The elastic element 34 is sandwiched between the other end of the suction plate 36 and the baffle 33. The elastic element 34 is used to apply an elastic force to the suction plate 36 to make it move horizontally toward a position close to the guide plate 37. The suction plate 36 is fixedly integrated with the anti-rotation pin 35. The suction plate 36 can drive the anti-rotation pin 35 to move synchronously, so that the anti-rotation pin 35 can be inserted into the limiting hole on the movable frame 25, so that the anti-rotation device can be switched to the locking state in time.

[0043] like Figures 7 to 9As shown, the height of the guide plate 37 is greater than the height of the pin 29. The suction plate 36 and the guide plate 37 are vertically arranged, and the length direction of the suction plate 36 and the guide plate 37 is parallel to the width direction of the frame 22. When the anti-rotation device is in the locked state, the anti-rotation pin 35 is simultaneously inserted into the guide hole and the limiting hole. The suction plate 36 is in contact with the guide plate 37, and the elastic element 34 is in the extended state. Under the elastic force applied by the elastic element 34, the anti-rotation pin 35 can always be inserted into the limiting hole, keeping the movable frame 25 stationary and ensuring good reliability. After the egg-turning rack 2 enters the incubation chamber 1 and moves into place, the heating tube 3 is switched to the working position. The pin 29 at the lower end of the movable frame 25 is inserted into the groove on the swing rod 26, and the movable frame 25 engages with the egg-turning actuator. Then, the anti-rotation device needs to be switched to the unlocked state. The anti-rotation pin 35 needs to be pulled out from the limiting hole of the movable frame 25 to release the limitation on the movable frame 25 before the egg-turning action can be performed. The suction plate 36 is made of metal. An electromagnet is installed in the incubation chamber 1. The electromagnet is powered by a power source and is used to attract the suction plate 36. When the electromagnet is energized, it can generate an attractive force on the suction plate 36, causing the suction plate 36 to move away from the guide plate 37. The suction plate 36 drives the anti-rotation pin 35 to move synchronously, and the elastic element 34 is compressed. Ultimately, the anti-rotation pin 35 can be pulled out from the limiting hole of the movable frame 25, releasing the limitation on the movable frame 25. Moreover, due to the limiting effect of the baffle 33 on the suction plate 36 in the second direction, the movement of the anti-rotation pin 35 can be controlled, so that the anti-rotation pin 35 will not move out of the guide hole of the guide plate 37. After the electromagnet is de-energized, it can no longer attract the suction plate 36. Under the action of the elastic element 34, the suction plate 36 moves toward the position close to the guide plate 37. The suction plate 36 drives the anti-rotation pin 35 to move synchronously, so that the anti-rotation pin 35 can be inserted into the limiting hole of the movable frame 25 to limit the movable frame 25.

[0044] The anti-rotation device switches between locked and unlocked states using an electromagnet, resulting in a simple structure, convenient layout, and easy control. Furthermore, before the electromagnet is energized, there is no direct collision between the electromagnet and the suction plate 36, preventing additional vibration. After the electromagnet attracts the suction plate 36, the anti-rotation device is in the unlocked state, with the anti-rotation pin 35 still inserted in the guide hole on the guide plate 37. Thus, the attraction between the electromagnet and the suction plate 36 contributes to the overall stability of the egg-turning rack 2, preventing it from wobbling.

[0045] Preferably, multiple anti-rotation pins 35 can be provided, all of which are arranged sequentially along the length of the suction plate 36. The number of suction plates 36 and electromagnets is the same as the number of anti-rotation pins 35. Each anti-rotation pin 35 is fixedly connected to one suction plate 36, and each electromagnet is engaged with one suction plate 36. All electromagnets are on the same straight line parallel to the first direction. An even number of baffles 33 are provided, arranged in pairs. Each suction plate 36 is located between two baffles 33, and multiple elastic elements 34 are provided between each baffle 33 and the suction plate 36.

[0046] like Figure 8 and Figure 9 As shown, in this embodiment, two anti-rotation pins 35 and two suction plates 36 are provided, and a total of four baffles 33 are provided, with each suction plate 36 located between two baffles 33. The elastic element 34 is a cylindrical helical spring and is a compression spring.

[0047] like Figure 7 As shown, the bottom of the frame 22 is equipped with four rollers arranged in a rectangular pattern. The bottom of the incubation chamber 1 is equipped with two guide rails for the rollers to embed in, with the length direction of the guide rails parallel to the second direction. During the process of the egg-turning rack 2 moving in and out of the incubation chamber 1, the rollers roll along the guide rails, which guide the egg-turning rack 2.

[0048] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
