In this poultry incubation device, by setting the incubation box, culture box, base, and clamping structure, through the cooperation between the limit rod, arc groove, and torsion spring, the arc-shaped plate can clamp and cultivate hatching eggs of different sizes, avoiding the phenomenon of instability or dropping of hatching eggs of different sizes during storage, reducing the probability of subsequent damage to hatching eggs, and effectively ensuring the applicability of this incubation device. However, this device still has the following problems:

[0004] 1. During the incubation process of poultry, it is necessary to conduct multiple candling inspections on the eggs to promptly remove abnormal eggs, and it is also necessary to disinfect the surface of the eggshell, and transfer the breeding eggs from the hatching tray to the hatching tray in a timely manner in the later stage of incubation. Therefore, the staff needs to perform multiple transfer operations on the hatching tray, and it is relatively inconvenient to transfer the hatching tray at a high place of the adjustable automatic egg-turning type hatching cart, and the manual labor intensity is relatively high.

[0005] 2. Inside the incubator, it is usually necessary to keep the temperature and humidity consistent everywhere to ensure the same incubation progress of the breeding eggs in the same batch, but the hatching eggs at different positions on this device are prone to have different incubation environments.

[0006] 3. The inner bottom of the incubation box is higher than the ground, which is not convenient for the adjustable automatic egg-turning type hatching cart to enter and exit the incubation box, and the bottom of some incubation boxes is made of cement and does not have space to place auxiliary tools such as ramps.

[0023] In order to better achieve the object of the present invention, the present invention also provides a method for using an incubator that is convenient for loading and unloading, including the following steps:

[0024] Step 1: Slide the ejector rod outward to the outside of the moving support structure, so that the drive shaft is disengaged from the sliding groove. Through the cooperation of the lifting device and the scissor assembly, reduce the spacing between all adjacent movable laminates, and let the operator fill all the movable laminates with hatching trays containing hatching eggs.

[0025] Step 2: Adjust the spacing between all adjacent movable laminates to a set size through the lifting device, and then reset the ejector rod so that the drive shaft is inserted back into the sliding groove.

[0026] Step 3: Push the adjustable automatic egg-turning type hatching cart into the hatching cavity, and lock the moving support structure after it is in place.

[0027] Step 4: Close the door panels, and through the linkage mechanism, automatically retract the support inclined blocks into the interior of the incubator.

[0028] Step 5: Control the humidity and temperature of the hatching cavity through the temperature and humidity control component, and control the processed air in the cavity to flow into the I-shaped temperature control pipe through the corrugated pipe and then flow out through the through holes.

[0029] Step 6: The I-shaped temperature control pipe reciprocates vertically in the hatching cavity to evenly supply air to the eggs in each layer of hatching trays on the adjustable automatic egg-turning type hatching cart. And while the I-shaped temperature control pipe is moving, the fan reciprocates and swings to disturb the air flow ejected from the through holes of the I-shaped temperature control pipe. The temperature and humidity sensor real-time monitors the humidity and temperature at each point in the hatching cavity.

[0030] Step 7: When egg turning is required, control the ejector block to move forward through the push cylinder to lift the ejector rod upward. The ejector rod, through the cooperation of the drive shaft and the sliding groove, synchronously lifts all the movable laminates, changes the inclination direction of the movable laminates, and realizes the egg-turning operation; after the ejector block is reset, under the action of gravity, the ejector rod descends, and the inclination direction of all the movable laminates is changed again, thereby completing the egg-turning operation again.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When loading and unloading the hatching trays on the inclined support assembly, sliding the synchronous lifting assembly outward from the support frame can disengage the synchronous lifting assembly from the inclined support assembly. At this time, the layer height synchronous adjustment assembly is used to control the spacing between all adjacent inclined support assemblies to shrink synchronously, reducing the layer height of the inclined support assembly, thereby facilitating the operation of the operator to pick up and place the hatching trays, effectively reducing the labor intensity of the operator, and reducing the possibility of accidental dropping of the hatching trays. When the inclined support assembly is refilled with hatching trays, after controlling all the inclined support assemblies to reset through the layer height synchronous adjustment assembly, the synchronous lifting assembly is reconnected to the inclined support assembly, so that there is sufficient space between the hatching trays on different layers to ensure air circulation, which is conducive to achieving the consistency of temperature and humidity in all parts of the hatching cavity.

[0032] 2. By controlling the engagement and disengagement of the synchronous lifting assembly and the inclined support assembly, power can be provided to the synchronous lifting assembly through the driving assembly, and the inclination direction of all movable laminates can be changed, enabling automatic egg turning operation. The same driving assembly can drive the synchronous lifting assemblies on different adjustable automatic egg turning type incubator carts to perform egg turning operations, reducing the usage cost. Moreover, by setting the number of sliding grooves on the ejector rod, egg turning operations at different layer heights of the movable laminates can be realized, meeting the space requirements of eggs of different varieties.

[0033] 3. The mouth-shaped temperature control pipe moves vertically back and forth under the limiting action of the sliding rod, uniformly blowing air into the eggs in the hatching trays on each layer of the adjustable automatic egg turning type incubator cart. At the same time as the mouth-shaped temperature control pipe moves, the fan swings back and forth, disturbing the air flow ejected from the through holes of the mouth-shaped temperature control pipe. The temperature and humidity sensor continuously monitors the humidity and temperature at each point in the hatching cavity, thereby ensuring the consistency of the hatching environment for the same batch of breeding eggs.

[0034] 4. By setting the linkage mechanism, when the door panel is opened, the supporting inclined block will automatically flip to facilitate the entry and exit of the adjustable automatic egg turning type incubator cart. When the door panel is closed, the supporting inclined block will automatically retract into the hatching cavity, preventing passing personnel or equipment from being blocked by the supporting inclined block.

[0075] Before adjusting the distance between adjacent movable shelves 231, it is necessary to release the locking of the fixed block 323 on the horizontal limiting block 322 so that the ejector rod 321 can slide outward to the outside of the support frame 21, so that the drive shaft 325 is disengaged from the sliding groove; after adjusting the distance between adjacent movable shelves 231, it is necessary to reset the ejector rod 321 so that the drive shaft 325 is inserted into the sliding groove again to restore the egg turning function of the movable shelf 231;

[0076] When egg turning is required, the push cylinder 312 is used to control the forward movement of the top block 311, so that the top block 311 jacks up the ejector rod 321 through the roller 313. The ejector rod 321 synchronously jacks up all the movable shelves 231 through the cooperation of the drive shaft 325 and the sliding groove, so that the movable shelf 231 rotates around the horizontal axis 233 to change its inclination direction, and the egg turning operation is realized. When the push cylinder 312 controls the backward movement of the top block 311, the ejector rod 321 descends under the action of gravity, so that the hanging plates 234 of all the movable shelves 231 are reattached to the cross braces 232, and the egg turning operation is completed again.

[0077] In some embodiments, such as Figure 12As shown, the number of sliding grooves on the ejector rod 321 is greater than the number of drive shafts 325; the distance between adjacent movable shelves 231 is adjusted by the lifting device 245, so that at different heights of the movable shelf 231, there are still corresponding sliding grooves for the drive shaft 325 to slide, realizing the egg turning operation at different heights of the movable shelf 231, meeting the space requirements of eggs of different varieties, and thus making the present application applicable to hatching eggs of different varieties.

[0078] In some embodiments, as Figures 2 - 5 shown, the surrounding temperature and humidity control mechanism 4 includes a temperature and humidity control component, a square-ring-shaped temperature control pipe 45, a corrugated pipe 46 and a temperature and humidity sensor 47. An all-round control mechanism 5 is further provided on the inner wall of the hatching cavity 102. The mobile end of the all-round control mechanism 5 is equipped with a square-ring-shaped temperature control pipe 45. The square-ring-shaped temperature control pipe 45 surrounds the adjustable automatic egg-turning type hatching cart 2. The all-round control mechanism 5 is used to drive the square-ring-shaped temperature control pipe 45 to reciprocate vertically in the hatching cavity 102. A number of through holes are evenly opened at equal intervals on the inner side of the square-ring-shaped temperature control pipe 45. One end of the corrugated pipe 46 is fixedly connected to the upper end of the partition plate, and the other end of the corrugated pipe 46 is fixedly connected to the square-ring-shaped temperature control pipe 45, so that the square-ring-shaped temperature control pipe 45 is communicated with the control cavity 101 through the corrugated pipe 46; a plurality of temperature and humidity sensors 47 are also evenly arranged on the square-ring-shaped temperature control pipe 45.

[0079] The temperature and humidity control component includes an atomizer 41, a heating wire 42, a blower 43 and an exhaust fan 44. The atomizer 41 for controlling humidity is fixedly installed at the bottom of the control cavity 101, the heating wire 42 for heating air is fixedly installed in the middle of the control cavity 101, the blower 43 is fixedly installed on the side wall of the partition plate located in the control cavity 101, the height of the blower 43 is lower than that of the heating wire 42, and the blower 43 is used to send the air in the hatching cavity 102 into the control cavity 101; the exhaust fan 44 is fixedly installed on the top of the hatching box 10, and the exhaust fan 44 is used to send the air in the hatching cavity 102 to the outside of the hatching box 10.

[0080] In some embodiments, please refer to Figure 5 and Figure 7The omnidirectional control mechanism 5 includes a slide bar 51, a screw rod 52, a motor 54, a first transmission assembly 55, a lifting block 57 and an auxiliary spoiler assembly. The two slide bars 51 are symmetrically fixedly installed at the left and right ends of the incubation chamber 102, and the screw rod 52 is located between the two slide bars 51. The upper and lower ends of the screw rod 52 are rotatably connected to the incubator 10 through bearings; the motor 54 is fixedly installed on the top of the incubator 10 through a bracket, and the output end of the motor 54 is connected to the screw rod 52 through the first transmission assembly 55; the first transmission assembly 55 can adopt a belt and pulley transmission structure; the slide bar 51 is limitedly slidably connected to the square-shaped temperature control tube 45, the screw rod 52 is threadedly connected to the lifting block 57 through a threaded sleeve, and the lifting block 57 is fixedly connected to the square-shaped temperature control tube 45; an auxiliary spoiler assembly is also provided in the incubation chamber 102;

[0081] The auxiliary spoiler assembly includes a swing rod 53, a reciprocating swing assembly 56, a movable sleeve 58 and a fan 59. The swing rod 53 is rotatably mounted inside the incubation chamber 102 through a bearing, and the output end of the motor 54 is connected to the swing rod 53 through the reciprocating swing assembly 56; the movable sleeve 58 is sleeved on the outside of the swing rod 53, and the movable sleeve 58 is rotatably connected to the lifting block 57 through a bearing; the fan 59 is fixedly connected to the movable sleeve 58;

[0082] The reciprocating swing component 56 includes a rotating disk 561, a swing column 562 and a swing block 563. The rotating disk 561 is fixedly installed at the lower end of the output end of the motor 54. The swing column 562 is fixedly installed at the eccentric part of the rotating disk 561. The swing block 563 is fixedly connected to the top end of the swing rod 53. The swing block 563 is provided with a sliding groove that is limitedly slidably connected to the swing column 562.

[0083] In the present invention, the atomizer 41 and the heating wire 42 are used to control the humidity and temperature of the incubation chamber 102 respectively. The air treated by the atomizer 41 and the heating wire 42 flows into the inlet-shaped temperature control tube 45 through the corrugated tube 46, and then flows out through the through hole to blow air evenly to the adjustable automatic egg-turning incubator 2; and the motor 54 controls the screw rod 52 to rotate, so that the inlet-shaped temperature control tube 45 moves vertically back and forth under the limiting action of the slide bar 51, and air is evenly supplied to the eggs in the incubation trays of each layer on the adjustable automatic egg-turning incubator 2. When the inlet-shaped temperature control tube 45 moves, the motor 54 also drives the rotating disk 561 to rotate, and the swing column 562 and the swing block 563 cooperate to make the swing rod 53 swing back and forth, and then the fan 59 swings back and forth through the movable sleeve 58, disturbing the airflow ejected from the through hole of the inlet-shaped temperature control tube 45, thereby ensuring the consistency of the incubation environment of the same batch of breeding eggs.

[0084] In some embodiments, Figure 1 and Figure 10As shown in the figure, the linkage mechanism 6 includes a door shaft 61, a connecting shaft 62, a bracket 63, and a second transmission component 64. The door shaft 61 is rotatably installed at the front end of the hatching chamber 102 through a bearing, and the door panel 11 is fixedly connected to the door shaft 61; the bracket 63 is fixedly connected to the inner bottom of the hatching chamber 102, the connecting shaft 62 is rotatably connected to the bracket 63 through a bearing, and one end of the connecting shaft 62 is fixedly connected to the support inclined block 13, and the other end of the connecting shaft 62 is drivingly connected to the door shaft 61 through the second transmission component 64;

[0085] The second transmission component 64 can adopt a bevel gear transmission structure. When the door shaft 61 rotates 90 degrees, the connecting shaft 62 rotates 180 degrees. Thus, when the door panel 11 is opened, the support inclined block 13 will automatically flip to facilitate the entry and exit of the adjustable automatic egg-turning hatching cart 2, and when the door panel 11 is closed, the support inclined block 13 will automatically retract into the hatching chamber 102.

[0086] In some embodiments, as Figures 1 - 12 shown, as a preferred embodiment of the present invention, a method for using an incubator that is convenient for loading and unloading includes the following steps:

[0087] Step 1: Slide the ejector rod 321 outward of the support frame 21 so that the drive shaft 325 is disengaged from the sliding groove. Control the pin shaft 247 at the highest position to move vertically downward through the lifting device 245, so that all the connecting rods 244 move vertically upward, reducing the spacing between all adjacent movable laminates 231. Then, an operator fills all the movable laminates 231 with hatching trays containing hatching eggs;

[0088] Step 2: Control the pin shaft 247 at the highest position to move vertically upward through the lifting device 245, adjust the spacing between all adjacent movable laminates 231 to a set size, and then reset the ejector rod 321 so that the drive shaft 325 is inserted back into the sliding groove;

[0089] Step 3: Push the adjustable automatic egg-turning hatching cart 2 into the hatching chamber 102 along the support inclined block 13 and the track 12. After the adjustable automatic egg-turning hatching cart 2 is in place in the hatching chamber 102, lock all the pulleys 22;

[0090] Step 4: Close the door panel 11. The door panel 11 drives the door shaft 61 to rotate. The door shaft 61 drives the connecting shaft 62 to rotate under the action of the second transmission component 64, so that the support inclined block 13 is automatically retracted into the incubator 10;

[0091] Step 5: Start the atomizer 41 and the heating wire 42 to control the humidity and temperature of the hatching chamber 102 respectively. The air processed by the atomizer 41 and the heating wire 42 flows into the I-shaped temperature control pipe 45 through the corrugated pipe 46 and then flows out through the through holes;

[0092] Step 6: The motor 54 controls the rotation of the lead screw 52, causing the rectangular temperature control pipe 45 to move vertically back and forth under the limiting action of the slide bar 51, evenly blowing air to the eggs in each layer of the incubation trays on the adjustable automatic egg-turning type incubation vehicle 2. Meanwhile, while the rectangular temperature control pipe 45 is moving, the motor 54 also drives the rotating disc 561 to rotate. The swing column 562 and the swing block 563 cooperate to cause the swing rod 53 to swing reciprocally, and further cause the fan 59 to swing reciprocally through the movable sleeve 58, disturbing the air flow ejected from the through holes of the rectangular temperature control pipe 45. The humidity and temperature sensor 47 monitors the humidity and temperature at each point in the incubation chamber 102 in real time;

[0093] Step 7: When egg turning is required, the push cylinder 312 controls the top block 311 to move forward, causing the top block 311 to push the top rod 321 upward through the roller 313. The top rod 321 synchronously pushes up all the movable laminates 231 through the cooperation of the drive shaft 325 and the sliding groove, causing the movable laminates 231 to rotate around the horizontal axis 233 and change their inclination direction to achieve the egg turning operation; when the push cylinder 312 controls the top block 311 to move backward, the top rod 321 descends under the action of gravity, causing the hanging plates 234 of all the movable laminates 231 to fit against the cross braces 232 again to complete the egg turning operation again.
