An adaptive chicken leg ring for encapsulating an RFID chip

Abstract

The application discloses a self-adaptive chicken foot ring for packaging RFID chips, and relates to the technical field of poultry breeding. The chicken foot ring comprises a detachable outer shell body which is locked through a connecting piece, and a self-adaptive adjusting mechanism which is used for following the change of the chicken foot to change synchronously so that the chicken foot ring is always attached to the chicken foot. The self-adaptive adjusting mechanism comprises a connecting shell body which is attached to the chicken foot and a plastic annular belt which is attached to the chicken foot. The chicken foot ring is actually divided into two adjustment modes during use. Firstly, the internal space is changed by using the first mode. When the first mode is adjusted to the last value, the second adjustment intervenes, so that the inner diameter can be further expanded, and the first mode is reset. Meanwhile, during the adjustment of the second mode, the elastic pull force of the first mode always plays a winding role on the second mode, so that the variable range of the chicken foot ring is large, and the chicken foot ring is always attached to the chicken foot, thereby effectively improving the actual use effect of the chicken foot ring.

Description

Technical Field

[0001] This invention relates to the field of poultry farming technology, and more particularly to an adaptive chicken leg band encapsulated with an RFID chip. Background Technology

[0002] Chicken leg bands are an innovative technology in modern poultry farming, mainly used to improve breeding efficiency and the precision of flock management. Chicken leg bands are usually made of plastic or metal and are fixed to the chicken's feet. The built-in microchip can record relevant information about the chicken, such as identification and activity level. By connecting with a smart system, farmers can monitor the health status of the flock, feed consumption, and environmental parameters in real time.

[0003] However, existing chicken leg bands lack an automatic adjustment mechanism to accommodate the varying thickness of the chicken's feet. Since chickens need to be tracked from a young age, leg bands with relatively large inner diameters are often used to reduce frequent replacements. However, chicks have thinner feet, and an unsuitable leg band moves up and down with their movement, causing chafing, wounds, and increasing the risk of infection. To address this, an adjustable leg band has been designed. However, in mass farming, chickens grow at different rates, and adjustments are often made in batches, making timely adjustments impossible. In such cases, the presence of the leg band can negatively impact the chickens. Summary of the Invention

[0004] The present invention addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The present invention provides an adaptive chicken leg band with an encapsulated RFID chip to solve the technical problem that existing chicken leg bands cannot automatically adjust their inner diameter according to the growth of chickens.

[0005] The present invention adopts the following technical solution: an adaptive chicken foot ring encapsulating an RFID chip, comprising a detachable outer shell that is locked by a connector, and an adaptive adjustment mechanism for synchronously changing with the chicken foot to always fit the chicken foot. The adaptive adjustment mechanism includes a connecting shell that fits the chicken foot and a plastic annular band that fits the chicken foot.

[0006] Furthermore, the plastic annular belt is made of a material with elastic deformation capability, such as thermoplastic elastomer and silicone.

[0007] Furthermore, the inner surface of the connecting housing is arc-shaped to better fit the chicken foot. A movable sliding plate is provided inside the connecting housing. A spring guide post is provided between the sliding plate and the connecting housing to guide the movement direction of the sliding plate. The connecting housing is divided into an installation cavity and a working cavity by the sliding plate. The installation cavity has space for installing the chip and is equipped with a deflection torsion spring. A connecting rod is provided outside the deflection torsion spring and passes through the sliding plate. One end of the plastic annular belt passes through the connecting housing, and the end of the plastic annular belt has several tapered grooves. The other end of the plastic annular belt is connected to the sliding plate by an additional connecting strip. A forming guide block is provided between the connecting housing and the plastic annular belt.

[0008] Furthermore, in the initial state, the connecting rod is tilted at an angle under the action of the deflection torsion spring.

[0009] Furthermore, the transition section between the conical grooves in the plastic annular belt is an arc surface.

[0010] Furthermore, the plastic annular belt end with the conical groove is slidably connected to the detachable outer shell.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: Firstly, during use, the actual inner diameter of this chicken leg ring is the total length of the plastic annular band and the connecting band. However, during use, the connecting band is located inside the connecting housing, resulting in an effective working length equal to the length of the plastic annular band (meaning the connecting band's length is a floating length; it exists, but its use is selective). As the chicken leg grows, it stretches the plastic annular band, which is locked by a conical insert block and a conical groove. However, since the plastic annular band is locked, the sliding plate is pulled to displace it, pulling out the existing connecting band. This is one extension action. When the connecting band is not long enough for extension, the conical insert block and the conical groove automatically release the restriction, causing the inner diameter of the plastic annular band to increase. The exact increase in size depends on the thickness of the chicken's foot. However, due to the compressed spring guide post, the plastic ring belt will also be tightened. This interaction prevents the conical insert from failing to fit properly when simply adjusting with the conical insert. In such cases, the conical insert might not be able to lock properly, and the plastic ring belt could be accidentally stretched again due to inertia or other external forces during the chicken's later walking and running, making it impossible to fit accurately. When disassembly is needed, simply open the detachable outer shell. The end of the plastic ring belt will deform outward under the action of the detachable outer shell, automatically releasing the restriction between the conical insert and the plastic ring belt, thus facilitating disassembly. In summary, this chicken leg ring has two adjustment modes during use. The first mode adjusts the internal space. As chickens grow, the difference in leg thickness increases, and the first mode alone may not be sufficient. Once the first mode reaches its maximum adjustment value, the second mode is engaged to further expand the inner diameter, while the first mode resets. Simultaneously, the elastic pull of the first mode continuously retracts the second mode during adjustment, preventing excessive adjustment at once or improper locking when using a snap-fit ​​mechanism (e.g., if it just happens to lock between two protrusions, it won't lock effectively, leading to unexpected expansion later). This allows for a wide range of adjustment while ensuring a consistent fit to the chicken's leg (compared to ordinary elastic bands, which generally have a limited elastic deformation capacity and increase pressure on the leg with stretching, this chicken leg ring provides a maximum pressure limit). This effectively improves the actual performance of the chicken leg ring. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0020] The following is combined Figures 1 to 5 As shown, this embodiment of the invention provides an adaptive chicken foot ring for encapsulating an RFID chip, including a detachable outer shell 1 that is locked by a connector, and an adaptive adjustment mechanism 2 for synchronously changing with the chicken foot to always fit the chicken foot. The adaptive adjustment mechanism 2 includes a connecting shell 21 that fits the chicken foot and a plastic annular band 28 that fits the chicken foot.

[0021] Specifically, the plastic annular belt 28 is made of a material with elastic deformation capability, such as thermoplastic elastomer and silicone.

[0022] When this material is used, the inner ring formed by the plastic ring belt 28 is not a fixed shape. This is because chicken feet do not grow into a regular circle during the growth process. Therefore, silicone material with a certain deformation ability is selected to better fit the chicken feet.

[0023] Specifically, the inner surface of the connecting housing 21 is arc-shaped to better fit the chicken foot. A sliding plate 24 is provided inside the connecting housing 21 for movement. A spring guide post 29 is provided between the sliding plate 24 and the connecting housing 21 to guide the movement direction of the sliding plate 24. The connecting housing 21 is divided into an installation cavity 22 and a working cavity by the sliding plate 24. The installation cavity 22 has space for installing the chip and a deflection torsion spring 23 is provided inside the installation cavity 22. A connecting rod 25 is provided outside the deflection torsion spring 23 and passes through the sliding plate 24. One end of the plastic annular belt 28 passes through the connecting housing 21 and has several tapered grooves at its end. The other end of the plastic annular belt is connected to the sliding plate 24 by an additional connecting strip 27. The connecting housing 21 and the plastic annular belt 28 are provided with forming guide blocks. The detachable outer shell 1 can also be made of a material with deformation capability, or the detachable outer shell 1 and the connecting housing 21 can be rotatably connected.

[0024] Specifically, in the initial state, the connecting rod 25 is tilted at an angle under the action of the deflection torsion spring 23.

[0025] Specifically, the transition section between the conical grooves in the plastic annular belt 28 is an arc surface.

[0026] During operation, since the conical grooves are arc-shaped, when the conical insertion block 26 is located on it, it can make a certain displacement, thereby cooperating with the reset of the spring guide post 29 to make displacement, thus facilitating better insertion.

[0027] Specifically, the end of the plastic annular belt 28 with the conical groove is slidably connected to the detachable outer shell 1.

[0028] During operation, the end of the plastic annular belt containing the conical groove can be moved, thereby making the inner diameter of the plastic annular belt 28 variable.

[0029] Working principle: When the chicken foot ring needs to be connected to the chicken foot, the detachable outer shell 1 is wrapped around the chicken foot. First, the plastic ring band 28 is pulled to reduce its inner diameter to a certain range, achieving a fit to the chicken foot. As the chicken grows, the diameter of its foot will change. The original inner diameter formed by the plastic ring band 28 is insufficient to accommodate the chicken. Therefore, the chicken foot will expand the plastic ring band 28 (i.e., the inner diameter of the chicken foot ring needs to be automatically adjusted). During the adjustment process, there are two adjustment modes. First, a small-range change in the internal space is used. In the single-stage adjustment mode, the connecting belt 27 is pulled outward under the action of the expansion force, thereby driving the sliding plate 24 connected to it to move outward. That is, at this time, the gap between the inner surface of the sliding plate 24 and the connecting housing 21 becomes smaller, compressing the spring guide post 29. During the movement of the sliding block, the inclined connecting rod 25 passing through it will be corrected, so that the conical insertion block 26 at the end of the connecting rod 25 will continuously move out of the insertion slot. Furthermore, as chickens grow, the difference in thickness between chicken feet becomes significant, and the single-stage mode alone may not be sufficient for use. When the single-stage mode is adjusted to the end... After the endpoint is reached, the conical insert block 26 is completely removed from the insertion slot, releasing the conical insert block 26 from restricting the plastic annular belt 28. At this point, the second-stage adjustment begins, and the inner diameter of the plastic annular belt 28 itself increases, further expanding the inner diameter. The expanded inner diameter of the plastic annular belt 28 no longer exerts a pulling effect on the sliding plate 24. The sliding plate 24 then resets under the action of the compressed spring guide post 29. This means that during the adjustment process in the second-stage mode, the elastic rebound force of the first-stage mode always has a winding effect on the second stage, preventing issues during the adjustment process in the second stage. In some cases, excessive adjustments at once, or adjustments made using a snap-fit ​​mechanism, may result in improper snap-fitting (e.g., if it snaps between two protrusions, it cannot lock effectively, leading to unexpected expansion later). This design allows for a wider range of adjustment for the chicken leg ring, ensuring a consistent fit to the chicken's foot. (Compared to ordinary elastic bands, which generally have a limited elastic deformation capacity and whose pressure on the chicken's foot increases with stretching, this chicken leg ring provides a maximum pressure limit.) This effectively improves the actual performance of the chicken leg ring.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
