Description

Technical Field

[0001] This utility model relates to the field of screening device technology, and in particular to an automatic screening device for hatching eggs in chicken hatching and breeding. Background Technology

[0002] In the chicken hatching and breeding industry, egg selection is a crucial preliminary step in ensuring chick quality and hatching efficiency. Egg quality directly affects the health, growth performance, and subsequent breeding profitability of the chicks. High-quality eggs increase hatching success rates, resulting in stronger chicks that are more beneficial for subsequent breeding and production. Therefore, accurate and effective egg selection is vital for the entire hatching and breeding industry chain. Currently, egg selection typically involves the following technologies:

[0003] 1. Appearance inspection technology: It can accurately identify defects such as cracks, stains, and deformities on the surface of hatching eggs, ensuring that the hatching eggs entering the incubation stage have a good appearance;

[0004] 2. Size measurement technology: Accurately measure the size of the hatching eggs. Different breeds of chickens have specific requirements for the size of hatching eggs, and hatching eggs of the appropriate size will have a better hatching effect.

[0005] 3. Internal quality inspection technology: For example, using egg candling technology to observe the size of the air cell, the position of the yolk, and the embryonic development inside the hatching egg to determine whether the hatching egg is suitable for incubation;

[0006] 4. Automated control technology: Enables automated operation of the screening process, improves screening efficiency, and reduces errors and costs caused by manual intervention.

[0007] Currently, various methods are used to screen hatching eggs. Some small farms still rely mainly on manual screening, with experienced workers using visual inspection and simple tools to select eggs based on their appearance, size, and other characteristics. Some medium-sized farms use semi-automatic screening equipment, such as conveyor belts to transport eggs, with workers assisting with testing using simple instruments, but this still requires a significant amount of manual judgment. Large farms may introduce relatively advanced automated screening systems that use optical detection, weight detection, and other technologies to automatically identify and remove substandard hatching eggs.

[0008] However, the above method has a prominent hardware structure problem: the requirements for the size of hatching eggs are not constant depending on different incubation purposes and market demands. For example, when incubating for the production of small chicken products or special breeds, relatively small hatching eggs may be selected, while for commercial incubation that pursues high yield and rapid growth, larger hatching eggs may be preferred. Therefore, in the actual screening process, the screening criteria will be adjusted according to specific needs. Existing devices that screen by size through conveying usually have baffles to limit the conveying path to prevent the hatching eggs from deviating during conveying. However, existing screening devices usually lack flexible and rapid spacing adjustment functions, and different blocking components need to be replaced when facing different screening needs, resulting in relatively low efficiency. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides an automatic egg sorting device for chicken hatching and breeding. It solves the problem that the requirements for egg size are not static depending on the hatching purpose and market demand. For example, when hatching for the production of small chicken products or special breeds, relatively small eggs may be selected, while for commercial hatching aiming for high yield and rapid growth, larger eggs may be preferred. Therefore, in the actual sorting process, the sorting criteria are adjusted according to specific needs. Existing devices that sort by size through a conveying method typically use baffles to limit the conveying path to prevent the eggs from deviating during transport. However, existing sorting devices usually lack flexible and rapid spacing adjustment functions, requiring the replacement of different blocking components to meet different sorting needs, resulting in relatively low efficiency.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] An automatic screening device for hatching and raising chicken eggs includes a base plate. A sliding limiting blocking mechanism is provided at the upper end of the base plate. The blocking mechanism includes two sliding seats and two limiting frames. The two sliding seats are slidably connected to the upper end of the base plate, and the two limiting frames are respectively fixedly connected to the upper ends of the two sliding seats. A pushing mechanism for driving the two sliding seats to slide is provided at the upper end of the base plate. The pushing mechanism includes a cylinder, which is fixedly connected to the upper end of the base plate. The two sliding seats are fixedly connected to the outer surface of the cylinder. A rotating mechanism for limiting the synchronous rotation of the two sliding seats is provided at the upper end of the base plate. The rotating mechanism includes a first connecting rod and two second connecting rods. The first connecting rod is rotatably connected to the upper end of the base plate, and the two second connecting rods are rotatably connected inside the first connecting rod and respectively rotatably connected inside the two sliding seats.

[0012] Preferably, two slide rails are fixedly connected to the upper end of the base plate.

[0013] Preferably, both of the limiting frames are fitted with rubber protective sleeves on their outer surfaces, and a conveyor belt mounting bracket is fixedly connected to the upper end of the base plate.

[0014] Preferably, the conveyor belt mounting support is equipped with a conveyor belt assembly.

[0015] Preferably, a feeding baffle is fixedly connected to the upper end of the conveyor belt mounting support, and a U-shaped mounting bracket is fixedly connected to the upper end of the base plate.

[0016] Preferably, two industrial cameras are fixedly connected to the inner surface of the U-shaped mounting bracket.

[0017] Preferably, a collection box is provided at the upper end of the base plate.

[0018] Preferably, a robotic arm is provided at the upper end of the base plate near the collection box, and a gripping suction cup is provided inside the robotic arm.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. When it is necessary to adjust the limiting distance of the egg conveying trajectory to adapt to different screening requirements, the pushing mechanism is activated, and the cylinder fixed at the upper end of the base plate starts to work. The cylinder directly pushes one of the sliding seats to slide. When the sliding seat slides, the second connecting rod connected to its lower end will squeeze the first connecting rod to rotate. When the first connecting rod rotates, it pulls the other second connecting rod, thereby driving the other sliding seat to slide synchronously. In this way, the two sliding seats can move synchronously, thereby driving the limiting frame fixed on their upper end to change position. It can accurately and quickly adjust the screening blocking distance. By flexibly adjusting the position of the limiting frame to change the limiting distance, it can adapt to the screening of eggs from various breeds of chickens.

[0021] 2. After the industrial camera takes pictures of the hatching eggs, the size of the eggs is analyzed. When the industrial camera identifies a hatching egg that does not meet the size requirements, it sends a signal to control the conveyor belt assembly to stop conveying. At this time, the robotic arm located at the upper end of the base plate near the collection box starts to work. The gripping suction cup inside the robotic arm moves to the position of the unqualified hatching egg under the drive of the robotic arm. The unqualified hatching egg is picked up by the gripping suction cup and then rejected. After rejection, the conveyor belt assembly continues to convey and collect qualified hatching eggs. The collected hatching eggs can be used for subsequent chicken hatching and breeding processes. The entire device realizes automatic detection and screening of hatching egg size through the coordinated work of various parts, improving the efficiency and accuracy of hatching egg screening.

Detailed Implementation

[0028] This application provides an automatic egg sorting device for chicken hatching and breeding, effectively solving the problem that the requirements for egg size are not constant depending on different hatching purposes and market demands. For example, when hatching for the production of small chicken products or special breeds, relatively small eggs may be selected, while for commercial hatching that pursues high yield and rapid growth, larger eggs may be preferred. Therefore, in the actual sorting process, the sorting criteria will be adjusted according to specific needs. Existing devices that sort by size through conveying typically have baffles to limit the conveying path to prevent the eggs from deviating during conveying. However, existing sorting devices usually lack flexible and rapid spacing adjustment functions. Different blocking components need to be replaced for different screening needs, which is relatively inefficient. When it is necessary to adjust the limiting distance of the egg conveying trajectory to adapt to different screening needs, the pushing mechanism is activated, and the cylinder fixed at the upper end of the base plate starts to work. The cylinder directly pushes one of the sliding seats to slide. When the sliding seat slides, the second connecting rod connected to its lower end will squeeze the first connecting rod to rotate. When the first connecting rod rotates, it pulls another second connecting rod, thereby driving the other sliding seat to slide synchronously. In this way, the two sliding seats can move synchronously, thereby driving the limiting frame fixed on their upper end to change position. It can accurately and quickly adjust the screening blocking distance. By flexibly adjusting the position of the limiting frame to change the limiting distance, it can adapt to the screening of eggs from various breeds of chickens.

[0029] Example

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application effectively solves the problem that the requirements for hatching egg size are not constant depending on different incubation purposes and market demands. For example, when hatching for the production of small chicken products or special breeds, relatively small hatching eggs may be selected, while for commercial incubation that pursues high yield and rapid growth, larger hatching eggs may be preferred. Therefore, in the actual screening process, the screening criteria will be adjusted according to specific needs. Existing devices that screen by size through conveying usually have baffles to limit the conveying path to prevent the hatching eggs from deviating during conveying. However, existing screening devices usually lack flexible and rapid spacing adjustment functions, and different blocking components need to be replaced when facing different screening needs, resulting in relatively low efficiency. The overall idea is as follows: An automatic hatching egg screening device for chicken hatching and breeding includes a base plate 11. A sliding limiting blocking mechanism is provided at the upper end of the base plate 11. The blocking mechanism includes two sliding seats 12 and two limiting frames 13. The two sliding seats 12 are slidably connected to the upper end of the base plate 11, and the two limiting frames 13 are respectively fixedly connected to the two sliding seats 12. At the upper end, the base plate 11 is provided with a pushing mechanism for driving the two sliding seats 12 to slide. The pushing mechanism includes a cylinder 14, which is fixedly connected to the upper end of the base plate 11. The two sliding seats 12 are fixedly connected to the outer surface of the cylinder 14. The upper end of the base plate 11 is provided with a rotating mechanism for limiting the synchronous rotation of the two sliding seats 12. The rotating mechanism includes a first connecting rod 15 and two second connecting rods 16. The first connecting rod 15 is rotatably connected to the upper end of the base plate 11, and the two second connecting rods 16 are rotatably connected inside the first connecting rod 15. The two second connecting rods 16 are respectively rotatably connected to the upper end of the base plate 11. Inside the two sliding seats 12, the two sliding seats 12 drive the limiting frame 13 to change its position, thereby blocking and limiting the conveying hatching eggs. The limiting frame 13 must be placed in a position that ensures a certain gap with the hatching eggs, limiting their conveying trajectory without causing obstruction. The cylinder 14 installed on the upper end of the base plate 11 directly pushes one of the sliding seats 12 to slide. When the sliding seat 12 slides, it will squeeze the first connecting rod 15 to rotate through the second connecting rod 16 connected to its lower end. The first connecting rod 15 pulls the two second connecting rods 16 to ensure the synchronicity of the sliding of the two sliding seats 12.

[0031] Two slide rails 17 are fixedly connected to the upper end of the base plate 11. Two sliding seats 12 are slidably connected to the outer surfaces of the two slide rails 17. Rubber protective sleeves 18 are fitted onto the outer surfaces of the two limit frames 13. A conveyor belt mounting support 19 is fixedly connected to the upper end of the base plate 11. The two sliding seats 12 are located on both sides of the conveyor belt mounting support 19. A conveyor belt assembly 21 is installed inside the conveyor belt mounting support 19. A feeding baffle 22 is fixedly connected to the upper end of the conveyor belt assembly 21. The feeding baffle 22 is located at the upper end of the conveyor belt assembly 21. A U-shaped mounting bracket 23 is fixedly connected to the upper end. The hatching eggs are placed on the inclined surface of the feeding baffle 22. The hatching eggs will slide along the surface of the feeding baffle 22 into the upper end of the conveyor belt assembly 21 and be conveyed upward by the conveyor belt assembly 21. The feeding baffle 22 is installed on the upper end of the conveyor belt mounting support 19 and does not contact the surface of the conveyor belt assembly 21. The feeding baffle 22, together with the limiting brackets 13 on both sides, forms two conveying lines. During the conveying process, the limiting distance of the two limiting brackets 13 is changed by sliding, thereby adapting to different screening requirements.

[0032] Two industrial cameras 24 are fixedly connected to the inner surface of the U-shaped mounting bracket 23. Both industrial cameras 24 are on the same vertical line as the feeding baffle 22. A collection box 25 is set at the upper end of the base plate 11. The collection box 25 and the conveyor belt assembly 21 are on the same horizontal line. A robotic arm 26 is set at the end of the upper end of the base plate 11 near the collection box 25. The robotic arm 26 is equipped with a gripping suction cup 27. During the screening process, the industrial cameras 24 take pictures and analyze the size of the hatching eggs. When a hatching egg with an unqualified size is found, the industrial camera 24 sends a signal to control the conveyor belt assembly 21 to stop conveying. At this time, the robotic arm 26 drives the gripping suction cup 27 to move and pick up the unqualified hatching eggs to achieve automatic screening. The qualified hatching eggs are transported to the gripping suction cup 27 for collection by the conveyor belt assembly 21.

[0033] To address the problems existing in the prior art, this utility model provides an automatic screening device for hatching eggs in chicken hatching and breeding. When it is necessary to adjust the limiting distance of the hatching egg conveying trajectory to adapt to different screening requirements, the pushing mechanism is activated, and the cylinder 14 fixed at the upper end of the base plate 11 starts to work. The cylinder 14 directly pushes one of the sliding seats 12 to slide. When the sliding seat 12 slides, the second connecting rod 16 connected to its lower end will squeeze the first connecting rod 15 to rotate. When the first connecting rod 15 rotates, it pulls the other second connecting rod 16, thereby driving the other sliding seat 12 to slide synchronously. In this way, the two sliding seats 12 can move synchronously, thereby driving the limiting frame 13 fixed at their upper ends to change position. It can accurately and quickly adjust the screening blocking distance. By flexibly adjusting the position of the limiting frame 13 to change the limiting distance, it can adapt to the screening of hatching eggs of various breeds of chickens.

[0034] Base plate 11: As the basic support structure of the entire automatic egg sorting device, it bears the weight of all other components, provides a platform for the installation and operation of each component, and its upper surface provides space for the layout of other components, ensuring the overall stability of the device and enabling the sorting work to be carried out in a stable environment.

[0035] Sliding seat 12: Both sliding seats 12 are slidably connected to the upper end of the base plate 11. They are key components for connecting and transmitting power. On the one hand, they are connected to the cylinder 14 and slide under the push of the cylinder 14. On the other hand, they cooperate with the rotating mechanism through the second connecting rod 16 connected at the lower end to drive the other sliding seat 12 to move synchronously. At the same time, they also support and drive the limit frame 13 fixed at its upper end to move, so as to adjust the limit distance of the hatching egg conveying trajectory.

[0036] Limiting frame 13: It acts as a barrier and limiter for the hatching eggs being transported. By adjusting its position and changing the limiting distance, it restricts the transport trajectory of the hatching eggs, ensuring that the hatching eggs move on a relatively standardized path, which facilitates subsequent screening operations. In addition, the limiting frame 13 maintains a certain gap with the hatching eggs, so it will not completely block the hatching eggs and ensure that the hatching eggs can be transported smoothly.

[0037] Cylinder 14: Fixedly connected to the upper end of the base plate 11, it is the core component of the pushing mechanism. It provides power for the sliding of the two sliding seats 12. Through the extension and retraction of the piston rod, it directly pushes one of the sliding seats 12, thereby driving the other sliding seat 12 to move synchronously, so as to adjust the position of the limiting frame 13 to adapt to the limiting distance requirements of different hatching egg screening.

[0038] First connecting rod 15: Rotatably connected to the upper end of the base plate 11, it is an important component of the rotating mechanism. When a sliding seat 12 slides under the push of the cylinder 14, the second connecting rod 16 connected to its lower end squeezes the first connecting rod 15 to rotate. The rotation of the first connecting rod 15 pulls the other second connecting rod 16, thereby ensuring the synchronicity of the sliding of the two sliding seats 12 and ensuring that the two limit frames 13 can change their positions simultaneously and equally, and accurately adjust the limit distance of the egg conveying trajectory.

[0039] There are two second connecting rods 16, both rotatably connected inside the first connecting rod 15 and rotatably connected inside the two sliding seats 12 respectively. They play the role of force transmission and motion conversion in the rotating mechanism. The linear motion of one sliding seat 12 is converted into the rotation of the first connecting rod 15 by pressing the first connecting rod 15. Then, the first connecting rod 15 pulls the other second connecting rod 16, which drives the other sliding seat 12 to move synchronously in a linear motion, so as to realize the synchronous movement of the two sliding seats 12 and finally make the two limit frames 13 change their positions synchronously.

[0040] Slide rail 17: Ensures the stability and straightness of the sliding seat 12 during the sliding process, enabling it to move accurately in the predetermined direction, thereby ensuring the accuracy of the position adjustment of the limit frame 13 and providing stable and reliable limit conditions for the screening of hatching eggs;

[0041] Rubber protective sleeve 18: The soft material of the rubber protective sleeve 18 can prevent hard collisions when the limit frame 13 comes into direct contact with the hatching egg, prevent cracks or damage on the surface of the hatching egg, and ensure the quality of the hatching egg.

[0042] Conveyor belt mounting bracket 19: It is fixedly connected to the upper end of the base plate 11 and is used to install and support the conveyor belt assembly 21. It is also equipped with a control box to receive feedback signals from the industrial camera 24 to control the start and stop of the conveyor belt assembly 21.

[0043] Conveyor belt assembly 21: Installed inside the conveyor belt mounting support 19, it is responsible for conveying hatching eggs from one end to the other. After the hatching eggs slide into the upper end of the conveyor belt assembly 21 along the feeding baffle 22, the conveyor belt assembly 21 starts and moves with the hatching eggs. During the conveying process, the hatching eggs pass under the industrial camera 24 for size detection. After screening, the qualified hatching eggs are conveyed to the designated location for collection. It is a key component for realizing the movement of hatching eggs in the hatching egg screening process.

[0044] Feeding baffle 22: It is fixedly connected to the upper end of the conveyor belt mounting support 19 and located at the upper end of the conveyor belt assembly 21. Its inclined surface facilitates the placement of hatching eggs. Under the action of gravity, the hatching eggs slide along this surface into the upper end of the conveyor belt assembly 21, realizing automatic feeding. In addition, the feeding baffle 22 cooperates with the limit frame 13 on both sides to form two conveying lines, standardizing the conveying path of hatching eggs and facilitating the industrial camera 24 to take pictures and analyze the size of hatching eggs. At the same time, it does not contact the surface of the conveyor belt assembly 21, avoiding interference with the feeding process.

[0045] U-shaped mounting bracket 23: It is fixedly connected to the upper end of the base plate 11, and two industrial cameras 24 are fixedly connected to its inner surface. The U-shaped mounting bracket 23 provides an installation position for the industrial cameras 24, ensuring that the industrial cameras 24 and the feeding baffle 22 are on the same vertical line, so that the industrial cameras 24 can clearly capture the hatching eggs being transported, and provide clear and accurate image data for hatching egg size analysis.

[0046] Industrial camera 24: During the egg transport process, the industrial camera 24 takes pictures of the eggs and analyzes the pictures to identify the size of the eggs. When an egg with an unqualified size is detected, a signal is sent to control the conveyor belt assembly 21 to stop transporting, triggering the subsequent operation of the robotic arm 26 to remove the unqualified eggs. It is a key component for realizing automatic detection and screening control of egg size.

[0047] Collection box 25: Used to collect qualified hatching eggs, providing storage space for qualified hatching eggs, which is convenient for subsequent use in the chicken hatching and breeding process;

[0048] Robotic arm 26: Robotic arm 26 is used to move the gripping suction cup 27 to the position of the defective hatching egg;

[0049] The gripping suction cup 27 is located inside the robotic arm 26 and works under the drive of the robotic arm 26. When it reaches the position of the unqualified hatching egg, the gripping suction cup 27 uses suction force to pick up the unqualified hatching egg and works with the robotic arm 26 to complete the removal of the unqualified hatching egg. It is the direct execution component for realizing the hatching egg screening and removal operation.

[0050] Working principle:

[0051] The first step involves placing the hatching eggs on the inclined surface of the feeding baffle 22. Due to the inclined angle of the feeding baffle 22, the hatching eggs will slide along its surface under gravity into the upper end of the conveyor belt assembly 21 located below. The conveyor belt assembly 21 inside the conveyor belt mounting support 19 is activated, conveying the hatching eggs to one end. The feeding baffle 22 is installed on the upper end of the conveyor belt mounting support 19 and does not contact the surface of the conveyor belt assembly 21. At the same time, it works in conjunction with the structure composed of sliding seats 12 and limiting frames 13 on both sides to form two conveying lines. This allows the hatching eggs to be conveyed on a relatively standardized path, facilitating subsequent screening operations. During the conveying process, two industrial cameras 24 fixed on the inner surface of the U-shaped mounting frame 23 take pictures of the hatching eggs. These two industrial cameras 24 are on the same vertical line as the feeding baffle 22, and can clearly capture the conveying process. After the industrial camera 24 takes pictures of the hatching eggs, it analyzes the size of the eggs. When the industrial camera 24 identifies hatching eggs that are not up to size, it sends a signal to control the conveyor belt assembly 21 to stop conveying. At this time, the robotic arm 26 located at the upper end of the base plate 11 near the collection box 25 starts to work. The gripping suction cup 27 inside the robotic arm 26 moves to the position of the unqualified hatching eggs under the drive of the robotic arm 26. The gripping suction cup 27 picks up the unqualified hatching eggs and removes them, completing the screening of unqualified hatching eggs. After the removal is completed, the conveyor belt assembly 21 continues to convey and collect qualified hatching eggs. The collected hatching eggs can be used for subsequent chicken hatching and breeding processes. The entire device realizes automatic detection and screening of hatching egg size through the coordinated work of various parts, improving the efficiency and accuracy of hatching egg screening.

[0052] The second step involves adjusting the limiting distance of the egg transport trajectory to adapt to different screening requirements. The pushing mechanism is activated, and the cylinder 14 fixed to the upper end of the base plate 11 begins operation. The cylinder 14 directly pushes one of the sliding seats 12 to slide. Both sliding seats 12 are slidably connected to the slide rail 17 at the upper end of the base plate 11. The slide rail 17 acts as a guide, ensuring the sliding seat 12 slides smoothly. When the sliding seat 12 slides, the second connecting rod 16 connected to its lower end squeezes the first connecting rod 15 to rotate. When the first connecting rod 15 rotates, it pulls the other second connecting rod 16, thereby causing the other sliding seat 12 to slide synchronously. Thus, the two sliding seats 12 can move synchronously, thereby causing the limiting frame 13 fixed to their upper ends to change position. The limiting frame 13 must be positioned to ensure a certain gap with the eggs, limiting the egg transport trajectory without obstructing egg movement. Simultaneously, the rubber protective sleeve 18 fitted onto the outer surface of the limiting frame 13 prevents damage to the eggs when the limiting frame 13 comes into direct contact with them.

[0053] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
