Description

Technical Field

[0001] This invention relates to the field of broiler chick sorting technology, and in particular to a broiler chick grading method, intelligent sorting device and system. Background Technology

[0002] In the large-scale hatching and breeding of white-feathered chickens, after the chicks hatch, they need to be graded and sorted. They are classified and screened according to their size, feather development, body shape and health status. The effect of grading and sorting the chicks directly affects the survival rate, uniformity of the flock and feed conversion efficiency in subsequent breeding.

[0003] Currently, chick sorting in hatcheries largely relies on manual visual inspection. This manual sorting is highly subjective, leads to worker fatigue from prolonged work, lacks standardized grading criteria, and results in frequent missorting and omissions. Sorting efficiency is limited, and labor costs remain high, making it unsuitable for the large-scale, continuous sorting needs of large-scale hatcheries. Existing automated chick sorting equipment typically uses conveyor belts to directly transport chicks, which can cause them to huddle together, run around, and squeeze each other. This not only increases the risk of stress and injury but also leads to chaotic chick postures during visual image acquisition, resulting in a high rate of misjudgment in image recognition. Therefore, this paper proposes a grading method, intelligent sorting device, and system for broiler chicks to address these problems. Summary of the Invention

[0004] To overcome the above shortcomings, this invention provides a method for grading white-feathered broiler chicks, an intelligent sorting device, and a system. The aim is to improve upon existing technologies where hatchery chick sorting relies heavily on manual visual inspection, which is subjective, prone to worker fatigue, suffers from inconsistent grading standards, and results in numerous errors and omissions, low sorting efficiency, and high labor costs. Furthermore, some automated sorting equipment uses ordinary conveyor belts to directly transport chicks, causing them to huddle together, squeeze each other, and suffer stress injuries. This also leads to a high rate of misjudgment in image recognition due to the chaotic postures of the chicks.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent sorting device for broiler chicks, comprising a fixed frame, a placement and conveying mechanism disposed on the fixed frame, a support frame fixedly connected to the fixed frame, and a sample sorting component disposed on the side wall of the fixed frame; the placement and conveying mechanism includes: A transmission disc is rotatably connected to a fixed frame, and a conveyor belt is driven to the transmission disc. A driving component is provided at the bottom of the fixed frame, and the driving component is used to drive the transmission disc to rotate. Sorting components, the sorting component array is arranged on the conveyor belt, and the sorting components move with the conveyor belt; The guide rail is fixedly connected to the mounting bracket.

[0006] As a further description of the above technical solution: The sorting assembly includes a fixed plate, a connecting column, a rotating wheel, a placement frame, and an electric telescopic rod. The fixed plate is slidably connected to the guide rail. The two ends of the connecting column are fixedly connected to the conveyor belt and the fixed plate, respectively. The rotating wheel is rotatably connected to the lower side of the fixed plate. The placement frame is hinged to the upper side of the fixed plate. The two ends of the electric telescopic rod are hinged to the fixed plate and the placement frame, respectively.

[0007] As a further description of the above technical solution: A baffle is hinged to the outer wall of the fixed plate, and a telescopic connecting rod is hinged to the placement frame. The telescopic end of the telescopic connecting rod is hinged to the baffle. A steel rope is fixedly connected to the sleeve of the telescopic connecting rod, and the end of the steel rope away from the telescopic connecting rod is fixedly connected to the telescopic end of the electric telescopic rod. A guide wheel is rotatably connected to the fixed plate, and the steel rope is driven through the guide wheel.

[0008] As a further description of the above technical solution: A protrusion one is fixedly connected to the sleeve of the telescopic link, and a protrusion two is fixedly connected to the outer wall of the placement frame. The protrusion one and the protrusion two are elastically connected by a tension spring.

[0009] As a further description of the above technical solution: The upper side of the fixing plate is fixedly connected to a limiting frame for horizontal support of the placement frame.

[0010] As a further description of the above technical solution: The guide rail is arrayed with multiple sets of ports.

[0011] As a further description of the above technical solution: The sample separation assembly includes a fixed frame, a collection frame, a fixed block, a positioning shaft, and a guide plate. The fixed frame is fixedly connected to the side wall of the fixed frame, the collection frame is placed in the fixed frame, the fixed block is fixedly connected to the inner surface of the collection frame, the positioning shaft is fixedly connected to the fixed block, the guide plate is rotatably connected to the positioning shaft, and a torsion spring is sleeved on the positioning shaft, with both ends of the torsion spring fixedly connected to the positioning shaft and the guide plate, respectively.

[0012] As a further description of the above technical solution: A limit block is fixedly connected to the outer wall of the fixed block to limit the guide plate.

[0013] A sorting system for broiler chicks, based on the aforementioned intelligent sorting device for broiler chicks, includes a machine vision module, a controller, and a host computer. The machine vision module includes a camera, which is electrically connected to a controller. The controller is electrically connected to the drive unit and the electric telescopic rod of the intelligent sorting device. The host computer is communicatively connected to the controller. The camera is used to capture images of the white-feathered chicken chicks inside the placement frame and transmit the captured image signals of the chicks to the controller. The controller has a built-in image recognition unit, which is used to receive image signals and complete the feature analysis of the chick's body shape, size, feather development status and health status, and output the grading judgment result; the controller outputs control signals according to the grading judgment result to control the electric telescopic rod of the corresponding work station to move, and at the same time controls the drive component to drive the transmission plate and conveyor belt to achieve cyclic conveying. The host computer is used to receive sorting data uploaded by the controller, configure sorting parameters, statistically analyze sorting results, record abnormal data, support operators to view the sorting quantity of each type of chicks, modify the grading judgment threshold, and send updates to the controller to the identification standard.

[0014] A grading method for broiler chicks, based on the aforementioned intelligent sorting device for broiler chicks, includes the following steps: S1. Parameter configuration: Enter the grading criteria for white-feathered chicken chicks into the host computer, set the threshold values ​​for body size, feathers, and health status for different grades of chicks, and send the configuration parameters to the controller. S2, Feeding: Place the white-feathered chicken chicks to be sorted into the placement boxes of each sorting component in sequence. The drive unit drives the transmission disc to drive the conveyor belt to rotate in a cycle. The sorting components follow the conveyor belt and make a circular cycle along the guide rail. S3. Image Acquisition and Recognition: When the placement frame containing the chicks moves to the recognition station below the camera, the camera acquires an image of the appearance of the chicks inside the placement frame and transmits the image information to the controller; the controller extracts features from the image, compares it with a preset grading threshold, and completes the chick grading determination. S4. Graded unloading: The sorting component carrying the chicks continues to move with the conveyor belt to the corresponding unloading station. The controller controls the electric telescopic rod of the station to extend. The electric telescopic rod pushes the placement frame to flip downward. At the same time, the telescopic connecting rod is pulled by the steel rope, which drives the baffle to rotate and open. The chicks fall from the flipped placement frame and are buffered by the guide plate into the collection frame of the corresponding sample sorting component. S5, Station Reset: After unloading, the electric telescopic rod retracts, and under the elastic force of the tension spring, the placement frame rotates back to the horizontal state. The baffle closes synchronously, the limit frame provides horizontal support for the placement frame, and the sorting component continues to circulate with the conveyor belt to enter the next loading and sorting process. S6. Data Statistics: Throughout the sorting process, the controller uploads the identification results and sorting categories of each chick to the host computer in real time. The host computer completes the statistics of the number of chicks of each type. When the collection box is full, it is replaced to continuously complete the batch chick grading and sorting.

[0015] The present invention has the following beneficial effects: 1. In this invention, by using an independent placement frame to hold a single white-feathered chick, and driving the sorting components to circulate through a ring conveyor mechanism, the phenomenon of chicks crowding together, squeezing each other and running around is effectively avoided, reducing stress and injury to the chicks. The placement frame provides relatively independent storage space, the chicks' posture is relatively stable, and it is easy for the camera to fully capture the appearance features of the chicks, reducing the probability of machine vision recognition misjudgment, eliminating the need for manual sorting, reducing interference from subjective human factors, improving sorting efficiency, reducing labor costs, and adapting to the needs of hatcheries for continuous sorting of large batches of chicks.

[0016] 2. In this invention, the electric telescopic rod moves during unloading, and the baffle opens synchronously through the linkage of the steel rope. During normal conveying, the baffle closes, which can prevent the chicks from jumping out of the placement frame and escaping. During unloading, the baffle can be opened as the placement frame flips, which facilitates the sorting of chicks.

[0017] 3. In this invention, the sample sorting component is equipped with a rotatable guide plate with a torsion spring. When the placement frame is flipped, the guide plate can be squeezed to rotate. When the chicks fall, the force is buffered and unloaded to avoid the chicks falling directly and causing collision damage. This balances the smoothness of unloading and the protection of the chicks, and reduces the defect rate of chicks during the sorting process. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Reference Figures 1-3 An embodiment of the present invention provides an intelligent sorting device for white-feathered chicken chicks, including a fixed frame 1, a placement and conveying mechanism 2 on the fixed frame 1, a support frame 3 fixedly connected to the fixed frame 1, and a sample sorting component 5 on the side wall of the fixed frame 1.

[0022] The conveying mechanism 2 includes a transmission disc 21, sorting components 23, and a guide rail 24. The transmission disc 21 is rotatably connected to a fixed frame 1, and a conveyor belt 22 is driven onto the transmission disc 21. A driving component is provided at the bottom of the fixed frame 1 to drive the transmission disc 21 to rotate. The sorting components 23 are arranged in an array on the conveyor belt 22 and move with the conveyor belt 22. The guide rail 24 is fixedly connected to the fixed frame 1. The driving component drives the transmission disc 21 to rotate, thereby driving the conveyor belt 22 to perform a circular cyclic motion. The conveyor belt 22 drives each sorting component 23 along the guide rail 24. The track 24 moves in a circular motion, and each chick is carried by an independent placement frame 234. The sorting component 23 is driven to circulate through the ring conveyor mechanism, which effectively avoids the phenomenon of chicks crowding together, squeezing each other and running around, and reduces the stress and injury of chicks. The placement frame 234 can provide a relatively independent holding space, and the chicks' posture is relatively stable, which makes it easy for the camera to fully capture the appearance features of the chicks, reducing the probability of machine vision recognition misjudgment, eliminating the need for manual sorting, reducing interference from human subjective factors, improving sorting efficiency, reducing labor costs, and adapting to the needs of hatcheries for continuous sorting of large batches of chicks.

[0023] Reference Figures 2-4The sorting assembly 23 includes a fixed plate 231, a connecting column 232, a rotating wheel 233, a placement frame 234, and an electric telescopic rod 235. The fixed plate 231 is slidably connected to the guide rail 24. The two ends of the connecting column 232 are fixedly connected to the conveyor belt 22 and the fixed plate 231, respectively. The rotating wheel 233 is rotatably connected to the lower side of the fixed plate 231. The placement frame 234 is hinged to the upper side of the fixed plate 231. The two ends of the electric telescopic rod 235 are hinged to the fixed plate 231 and the placement frame 234, respectively. The movement of the conveyor belt 22 can drive the connecting column 232 to move, which in turn drives the fixed plate 231 to move, so that the rotating wheel 233 moves in the guide rail 24, thereby ensuring that the sorting assembly 23 moves smoothly and steadily.

[0024] Furthermore, a baffle 236 is hinged to the outer wall of the fixed plate 231, and a telescopic connecting rod 237 is hinged to the placement frame 234. The telescopic end of the telescopic connecting rod 237 is hinged to the baffle 236. A steel rope 238 is fixedly connected to the sleeve of the telescopic connecting rod 237, and the end of the steel rope 238 away from the telescopic connecting rod 237 is fixedly connected to the telescopic end of the electric telescopic rod 235. A guide wheel 239 is rotatably connected to the fixed plate 231, and the steel rope 238 is drivenly connected to the guide wheel 239. When unloading, the electric telescopic rod 235 moves, and the baffle 236 opens synchronously through the linkage of the steel rope 238. The guide wheel 239 guides and reverses the steel rope 238, reducing the frictional loss of the steel rope 238. During normal conveying, the baffle 236 closes to prevent the chicks from jumping out of the placement frame 234 and escaping. When unloading, the baffle 236 can be opened by flipping the placement frame 234, which facilitates the sorting of chicks.

[0025] Furthermore, the guide rail 24 is arrayed with multiple sets of ports 241 for subsequent discharge of dust and impurities from the guide rail 24.

[0026] Furthermore, a protrusion 2310 is fixedly connected to the sleeve of the telescopic link 237, and a protrusion 2311 is fixedly connected to the outer wall of the placement frame 234. The protrusion 2310 and the protrusion 2311 are elastically connected by a tension spring. When the electric telescopic rod 235 retracts to complete the unloading, the tension spring drives the telescopic link 237 to reset, thereby driving the baffle 236 to rotate and close.

[0027] Furthermore, a limit frame 2312 is fixedly connected to the upper side of the fixing plate 231 for horizontal support of the placement frame 234.

[0028] Reference Figures 5-6The sorting component 5 includes a fixed frame 51, a collection frame 52, a fixed block 53, a positioning shaft 54, and a guide plate 55. The fixed frame 51 is fixedly connected to the side wall of the fixed frame 1. The collection frame 52 is placed in the fixed frame 51. The fixed block 53 is fixedly connected to the inner surface of the collection frame 52. The positioning shaft 54 ​​is fixedly connected to the fixed block 53. The guide plate 55 is rotatably connected to the positioning shaft 54. A torsion spring is sleeved on the positioning shaft 54, and the two ends of the torsion spring are fixedly connected to the positioning shaft 54 ​​and the guide plate 55, respectively. The sorting component 5 has a rotatable guide plate 55 with a torsion spring inside. When the placement frame 234 is flipped to unload, the chicks fall and come into contact with the guide plate 55, which can squeeze the guide plate 55 to rotate. The chicks are cushioned when they fall, avoiding direct fall and collision damage. This balances unloading smoothness and chick protection, reducing the defect rate of chicks during the sorting process. The torsion spring can drive the guide plate 55 to complete automatic reset, ready to receive the next batch of chicks.

[0029] Furthermore, a limiting block 531 is fixedly connected to the outer wall of the fixing block 53 to limit the guide plate 55.

[0030] A sorting system for broiler chicks includes a machine vision module, a controller, and a host computer; The machine vision module includes camera 4, which is electrically connected to the controller. The controller is electrically connected to the drive unit and the electric telescopic rod 235 of the intelligent sorting device. The host computer is connected to the controller for communication. Camera 4 is used to capture images of the white-feathered chicken chicks inside the placement frame 234 and transmit the captured image signals of the chicks to the controller. The controller has a built-in image recognition unit to receive image signals and perform feature analysis on the chick's body shape, size, feather development, and health status, and output the grading judgment result. The controller outputs control signals based on the grading judgment result to control the electric telescopic rod 235 of the corresponding workstation to move, and at the same time controls the drive component to drive the transmission disc 21 and the conveyor belt 22 to achieve cyclic conveying. The host computer is used to receive sorting data uploaded by the controller, configure sorting parameters, statistically analyze sorting results, and record abnormal data. It allows operators to view the sorting quantity of each type of chick, modify the grading threshold, and send updates to the controller to the identification standards.

[0031] A grading method for white-feathered chicken chicks includes the following steps: S1. Parameter configuration: Enter the grading criteria for white-feathered chicken chicks into the host computer, set the threshold values ​​for body size, feathers, and health status for different grades of chicks, and send the configuration parameters to the controller. S2, Feeding: Place the white-feathered chicken chicks to be sorted into the placement frames 234 of each sorting component 23 in sequence. The drive unit drives the transmission disc 21 to drive the conveyor belt 22 to rotate in a cycle. The sorting component 23 follows the conveyor belt 22 and moves in a circular cycle along the guide rail 24. S3. Image Acquisition and Recognition: When the placement frame 234 containing the chicks moves to the recognition station below the camera 4, the camera 4 acquires an image of the appearance of the chicks inside the placement frame 234 and transmits the image information to the controller; the controller extracts features from the image, compares it with the preset grading threshold, and completes the chick grading determination. S4. Graded unloading: The sorting component 23 carrying the chicks continues to move with the conveyor belt 22 to the corresponding unloading station. The controller controls the electric telescopic rod 235 of the station to extend. The electric telescopic rod 235 pushes the placement frame 234 to flip downward. At the same time, the telescopic connecting rod 237 is pulled by the steel rope 238, which drives the baffle 236 to rotate and open. The chicks fall from the flipped placement frame 234 and are buffered by the guide plate 55 before falling into the collection frame 52 of the corresponding sample sorting component 5. S5, Station Reset: After unloading, the electric telescopic rod 235 retracts, and under the elastic force of the tension spring, the placement frame 234 rotates back to the horizontal state. The baffle 236 closes synchronously, and the limit frame 2312 provides horizontal support for the placement frame 234. The sorting component 23 continues to run in a cycle with the conveyor belt 22 and enters the next feeding and sorting process. S6. Data Statistics: Throughout the sorting process, the controller uploads the identification results and sorting categories of each chick to the host computer in real time. The host computer completes the statistics of the number of chicks of each type. When the collection box 52 is full, it is replaced to continuously complete the batch chick grading and sorting.
