Description

Technical Field

[0001] This invention relates to the field of duck breeding technology, and in particular to a smart tagging and egg-laying breeding device for ducks. Background Technology

[0002] Due to the rigid requirements of breeding and natural mating, breeding ducks still rely on net-bed or floor-raising methods. Production practice shows that, influenced by multiple factors such as breed, environment, nutrition, and disease, approximately 20% of breeding ducks are typically low-producing or have ceased laying eggs. In recent years, precision animal husbandry and non-contact animal behavior monitoring technologies have developed rapidly. However, in terms of the precise screening and intervention of low-producing breeding ducks, technological evolution is facing significant bottlenecks, mainly due to the following three major technical challenges: First, traditional contact sensing technology is poorly adapted to waterfowl farming scenarios: Early animal individual monitoring widely used contact sensing networks such as radio frequency identification (RFID) for tracking, but the unique wading habits of waterfowl and the high humidity of the farming environment can easily cause short circuits and damage to electronic components, drastically reducing the lifespan of the equipment. In addition, forcing ducks to wear wearable devices can induce prolonged physiological stress and even cause local skin infections, which is not only inconsistent with animal welfare but also seriously interferes with the normal egg-laying physiological cycle. Second, there is a disconnect between digital recognition and physical capture in machine vision monitoring: Although non-contact vision monitoring technology is gradually emerging, in actual production, existing vision monitoring systems can often only output two-dimensional digital coordinates of the target individual on the software side to display the location of the duck flock. The breeder is unable to accurately lock and capture specific low-yield targets in the physical space based solely on the digital coordinates, resulting in a serious disconnect between the phenotypic screening model and the execution terminal. Third, the failure to promptly eliminate inefficient individuals leads to serious resource waste and biosecurity risks: Due to the aforementioned gaps in screening and implementation, the continued feeding of a large number of low-yield or non-producing breeding ducks consumes a significant amount of feed resources and causes environmental pollution. Furthermore, low-yield individuals caused by disease also pose a risk of disease transmission. Summary of the Invention

[0021] Please see Figures 1 to 5This invention discloses an intelligent tagging and egg-laying breeding device for breeding ducks, comprising a mesh bed 101 and independent egg-laying nests 02. The independent egg-laying nests 02 are arranged around the mesh bed 101, and bedding material is placed inside each nest. The independent egg-laying nests 02 can be rectangular, arc-shaped, etc. The device also includes several independent egg-laying nests 1, arranged inside the independent egg-laying nests 02. The height of each independent egg-laying nest 1 must be greater than 1.2 meters to prevent the ducks from being startled and flying onto the nests. To prevent data system chaos and false triggering, an elevated platform 2 is installed on one side of the bottom of the independent egg-laying nest 1. A weighing device 3 is installed on the top of the elevated platform 2. The weighing device 3 is electrically connected to the controller 14, and can transmit the weighing data from the weighing device 3 to the controller 14. An entry ramp 4 is provided on the side of the elevated platform 2 away from the independent egg-laying nest 1. An extension frame 5 is integrally provided on the top of the independent egg-laying nest 1. A fixing frame 6 is fixedly installed on the top of the extension frame 5. There are two fixing frames 6, and a [missing information - likely a device or mechanism] is installed between the two fixing frames 6. A storage cylinder 7 has a rotating shaft 8 fixedly installed in its middle. The rotating shaft 8 is rotatably connected to two fixed frames 6 via bearings. Six storage cavities 9 are arranged in a circular array around the central axis of the storage cylinder 7. Each storage cavity 9 contains a pigment spray can 10, and the six storage cavities 9 are used to store six different pigment spray cans 10. The pigments inside the pigment spray cans 10 are composed of safe, water-resistant, and non-toxic dyes. The extension frame 5 has a contact point at its end away from the independent egg-laying nest 1. The triggering component 11 of the pigment spray can 10 is provided. One end of the storage cylinder 7 is provided with perforations 12 in a ring array at the spraying end of the pigment spray can 10. The spraying angle of the pigment spray can 10 is set towards the center of the perforations 12. The pigment in the pigment spray can 10 can pass through the perforations 12 and be sprayed onto the body of the breeding duck. An adjustment component 13 for controlling the rotation of the storage cylinder 7 is installed between the extension frame 5 and the storage cylinder 7. A controller 14 is fixedly installed on the top of the independent laying nest 1. The controller 14 contains a system for processing data.

[0022] As one implementation method, such as Figures 1 to 5 As shown, side baffles 16 are fixedly installed on both sides of the independent egg-laying nest 1, and the side baffles 16 cover the areas on both sides of the weighing device 3 and the entry ramp 4.

[0023] In practice, the side baffle 16 can restrict the breeding ducks from leaving the independent laying nest 1, preventing them from leaving the weighing device 3 and the ramp 4.

[0024] As one implementation method, such as Figures 1 to 5As shown, a front baffle 17 is rotatably mounted on the end of the extension frame 5 away from the independent egg-laying nest 1 via a pivot pin. A first electric push rod 18 is symmetrically mounted on the lower surface of the extension frame 5 via a pivot pin. The moving end of the first electric push rod 18 is rotatably connected to one side of the front baffle 17 via a pivot pin. The first electric push rod 18 is electrically connected to the controller 14.

[0025] In practice, after the breeding ducks have passed over the weighing device 3 and been weighed, the front baffle 17 can block the ducks' path to prevent them from walking out of the entrance ramp 4 too quickly, thus preventing the paint sprayer 10 from effectively spraying color onto the ducks' bodies. After the ducks have been weighed by the weighing device 3, the controller 14 will receive the weighing data. At this time, the controller 14 will control the first electric push rod 18 to operate, thereby driving the front baffle 17 to rotate, canceling the blockage of the ducks' path by the front baffle 17, and the ducks can walk out of the entrance ramp 4.

[0026] As one implementation method, such as Figures 1 to 5 As shown, the trigger assembly 11 includes a second electric push rod 111 and a squeezing block 112. The second electric push rod 111 is fixedly installed on the middle of the upper surface of the end of the extension frame 5 away from the independent egg-laying nest 1. The squeezing block 112 is fixedly installed on the moving end of the trigger assembly 11. The squeezing block 112 is in squeezing contact with the pressing end of the pigment spray can 10. The second electric push rod 111 is electrically connected to the controller 14.

[0027] In practice, after the breeding ducks lay eggs, they leave their independent laying nests 1 and undergo a second weighing on the weighing device 3. The controller 14 will receive the weighing data. When there is no weighing data on the weighing device 3, it means that the breeding ducks have left the weighing device 3 and are on the entrance ramp 4. At this time, the controller 14 will control the second electric push rod 111 to operate. The second electric push rod 111 will control the extrusion block 112 to extrude the pressing end of the pigment spray can 10. The pigment in the pigment spray can 10 will pass through the perforation 12 and be sprayed onto the breeding ducks to mark them.

[0028] As one implementation method, such as Figures 1 to 5 As shown, the adjustment assembly 13 includes a driven gear 131, an adjustment motor 132, and a driving gear 133. The driven gear 131 is fixedly installed on the outside of the storage cylinder 7. The adjustment motor 132 is fixedly installed on the upper surface of the extension frame 5. The driving gear 133 is fixedly installed on the output end of the adjustment motor 132. The driving gear 133 is meshed with the driven gear 131. The adjustment motor 132 is electrically connected to the controller 14.

[0029] In practice, when marking a breeding duck with one color and then needing to mark it with another color, the controller 14 controls the motor 132 to be powered on, which in turn controls the drive gear 133 to rotate. The meshing of the drive gear 133 and the driven gear 131 drives the storage cylinder 7 to rotate, and the next pigment spray can 10 inside the storage cylinder 7 can be adjusted to the lowest position, so that a different color can be used when marking the breeding duck next time.

[0030] As one implementation method, such as Figures 1 to 5 As shown, a positioning baffle 19 is rotatably mounted on the end of the storage cylinder 7, corresponding to the end position of the storage cavity 9, with the central axis of the storage cylinder 7 as the axis, via a ring array of pins. The positioning baffle 19 can close the end of the storage cavity 9. One side of the positioning baffle 19 is in contact with the bottom end of the pigment spray can 10. A sliding hole 20 is provided on the positioning baffle 19. A positioning rod 21 is slidably installed inside the sliding hole 20. A spring 22 is sleeved on the outer side of one end of the positioning rod 21. One end of the spring 22 is fixedly connected to the end of the positioning rod 21, and the other end of the spring 22 is fixedly connected to one side of the positioning baffle 19. A positioning hole 23 is provided on the end of the storage cylinder 7 near the positioning baffle 19, with the central axis of the storage cylinder 7 as the axis, via a ring array of pins. The positioning hole 23 is slidably inserted into the positioning rod 21.

[0031] In practice, when installing or replacing the pigment spray can 10, the positioning rod 21 is pulled and slid inside the sliding hole 20. At this time, the positioning rod 21 will slide out of the positioning hole 23, and the spring 22 will be in a stretched state. Then, the positioning baffle 19 is controlled to rotate, and the sealing of the end of the storage cavity 9 by the positioning baffle 19 is canceled. The used pigment spray can 10 can be taken out from the storage cavity 9 or placed inside the storage cavity 9. Then, the positioning baffle 19 is rotated in the opposite direction, and the positioning baffle 19 is controlled to rotate to the position that seals the storage cavity 9. The pulling of the positioning rod 21 is canceled, and the positioning rod 21 can be slid into the positioning hole 23 by the pulling of the end of the positioning rod 21 by the spring 22. This can realize the re-sealing of the end of the storage cavity 9 by the positioning baffle 19 and the positioning of the pigment spray can 10.

[0032] As one implementation method, such as Figures 1 to 5 As shown, the outer wall of the storage cylinder 7 is provided with a pigment plane 24 corresponding to the position of the storage cavity 9, and the pigment color in the pigment spray can 10 at the corresponding position is sprayed onto the pigment plane 24.

[0033] In practice, the pigment in the pigment spray can 10 can be sprayed onto the pigment plane 24, and pigment spray cans 10 with the same pigment can be placed inside the corresponding storage cavity 9, so that people can easily determine the placement of pigment spray cans 10 containing different colors.

[0034] As one implementation method, such as Figures 1 to 5 As shown, the surface of the entrance ramp 4 is provided with anti-slip strips 25.

[0035] In practice, the anti-slip strip 25 can increase the friction between the feet of the breeding ducks and the ramp 4, thereby improving the stability of the breeding ducks moving on the ramp 4.

[0036] As one implementation method, such as Figures 1 to 5 As shown, a vision camera 15 is fixedly installed on the lower surface of the end of the extension frame 5 away from the independent egg-laying nest 1, and the vision camera 15 is electrically connected to the controller 14.

[0037] In practice, the vision camera 15 can monitor in real time whether the pigment spray can 10 is spraying color and whether there is pigment in the pigment spray can 10. The use of the vision camera 15 is based on the principle of vision detection and is a mature existing technology.

[0038] As one implementation method, such as Figures 1 to 5 As shown, the operating frequency of the regulating motor 132 is adjustable.

[0039] In practice, the rotation speed of the storage cylinder 7 can be adjusted by adjusting the working frequency of the regulating motor 132, which can shake the pigment spray can 10 inside the storage cylinder 7, thereby controlling the operation of the pigment spray can 10 to spray color. This operation is the same as the operation principle of shaking the pigment spray can 10 before using it in the prior art.

[0040] The working principle of this invention is: Several independent laying nests 1 are set inside the independent laying nests 02 around the wire mesh bed 101 to fix the installation position of the independent laying nests 1. When the breeding ducks enter the independent laying nests 1 through the entrance ramp 4 and the weighing device 3 to lay eggs, the weighing device 3 weighs the breeding ducks for the first time and transmits the weight data to the data processing system in the controller 14, automatically recording the current weight of the breeding ducks. When the breeding ducks leave the independent laying nests 1, they will be weighed a second time by the weighing device 3. When the difference between the two weight data is lower than a specified value, it is defined as no egg laying, and the system does not perform any operation. When the difference between the two weight data is greater than or equal to the specified value, it is defined as egg laying. When there is no weight data on the weighing device 3, it means that the breeding ducks have walked out of the weighing device 3 and are on the entrance ramp 4. At this time, the controller 14 will control the second electric push rod 111 to operate. The second electric push rod 111 will control the extrusion block 112 to extrude the pressing end of the pigment spray can 10, and the pigment spray can 10 will be filled with oil. The pigment is sprayed onto the breeding ducks through the perforation 12 to mark them. Then, the controller 14 controls the motor 132 to operate, which in turn controls the drive gear 133 to rotate. The meshing of the drive gear 133 and the driven gear 131 drives the storage cylinder 7 to rotate. The next pigment spray can 10 inside the storage cylinder 7 can be adjusted to the lowest position, so that a different color can be used when marking the breeding ducks next time. The controller 14 records the color spraying of the breeding ducks in different colors according to their age. The controller 14 records the color spraying in six colors as a basic recording cycle, which can accurately grasp the egg production situation. The egg production is recorded in 12-day cycles. During daily feeding, the color on the breeding ducks can be observed to accurately identify the target breeding ducks that have not laid eggs for a continuous period of time. This will not cause long-term physiological stress or local infection to the laying ducks. Inefficient breeding ducks can be culled in time, thereby reducing the feed cost and environmental pollution of the farm. When installing or replacing the pigment spray can 10, the positioning rod 21 is pulled and slid inside the sliding hole 20. At this time, the positioning rod 21 will slide out of the positioning hole 23, and the spring 22 will be in a stretched state. Then, the positioning baffle 19 is controlled to rotate, and the sealing of the end of the storage cavity 9 by the positioning baffle 19 is released. The used pigment spray can 10 can be taken out of the storage cavity 9 or placed inside the storage cavity 9. Then, the positioning baffle 19 is rotated in the opposite direction, and the positioning baffle 19 is controlled to rotate to the position that seals the storage cavity 9. The pulling of the positioning rod 21 by the spring 22 can slide the positioning rod 21 into the positioning hole 23. This can realize the resealing of the end of the storage cavity 9 by the positioning baffle 19 and the positioning of the pigment spray can 10, which can facilitate the replacement of the pigment spray can 10 and is simple to operate.
