[0030] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0031] The condition of tail feathers can reflect the health status and nutritional level of chickens, serving as an auxiliary indicator for assessing poultry production performance. Measurement data can provide reference for management practices such as adjusting rearing space and nutritional ratios. Among these, chicken feathers are one of the important external characteristics reflecting breed and sex, directly reflecting the growth and health status of broilers. Their long, upturned tail feathers are one of the most visually direct factors affecting the profitability of broiler farming.

[0032] In the breeding of high-quality broiler chickens, it is necessary to measure the length, height, and curvature of tail feathers to facilitate selection. Traditionally, tail feather measurements are performed manually using a measuring tape. However, this method is time-consuming and labor-intensive, and the results may be subject to subjective errors. It requires a significant investment of time by poultry farmers to measure tail feathers, and large-scale measurements often suffer from low accuracy.

[0033] In order to facilitate the breeding needs of farmers, the functional components for measuring chicken tail feathers are constantly being improved.

[0034] To address the aforementioned technical problems, this disclosure provides a chicken tail feather measuring device. For ease of description, broiler chickens will be used as an example to measure chicken tail feathers using this disclosure.

[0035] In one embodiment of this disclosure, the chicken tail feather measuring device includes a positioning member and a measuring member. The positioning member includes a first region and a second region connected together. The first region extends along a first direction to form a connecting portion, and the measuring member and the positioning member are detachably assembled via the connecting portion. The second region defines a fixing portion. The fixing portion is used to fix the broiler's tailbone, so that the broiler's tail is relatively fixed to the measuring member. The measuring member extends along a second direction to form a measuring area, and the plane containing the second direction intersects the plane containing the first direction.

[0036] Furthermore, in this embodiment, the measurement area has a labeling system. This labeling system is used to directly read the measurement dimensions of the chicken tail feathers when the fixing part is fixed to the broiler's tailbone. Compared to the measuring tape used in related technologies, using this disclosure to measure chicken tail feathers reduces measurement errors caused by different operators, saves time and effort, and increases measurement speed.

[0037] The chicken tail feather measuring device provided in this disclosure assembles and fixes the measuring component and the positioning component through a connecting part, and fixes the positioning component at the chicken's tailbone through a fixing part, so that the measuring component and the chicken's tail are relatively fixed. The measurement size of the chicken tail feather to be measured is directly read through the marking system of the measurement area. Compared with the tape measure used in related technologies, when using this disclosure to measure chicken tail feathers, the measurement error caused by different operators is reduced, the operation is time-saving and labor-saving, the measurement speed is improved, and it is convenient for operators to carry out appearance selection. That is, it is beneficial for operators to conduct efficient and accurate measurement of tail feather characteristics, thereby improving the breeding efficiency of chicken appearance traits. The embodiments of this disclosure meet the current needs for measuring chicken tail feathers while improving measurement accuracy, which helps to improve the efficiency of poultry selection.

[0038] Figure 1 This is a perspective view of a chicken tail feather measuring device according to an exemplary embodiment. Figure 2 This is a diagram illustrating the usage state of a chicken tail feather measuring device according to an exemplary embodiment. Figure 3 This is a perspective view of a positioning element in a chicken tail feather measuring device according to an exemplary embodiment. (Refer to...) Figure 1-3 As shown, the chicken tail feather measuring device includes: a positioning element 10 and a measuring element 20.

[0039] The positioning member 10 includes a first region and a second region connected together. The first region extends along a first direction to form a connecting portion 11, and the second region defines a fixing portion 12 for fixing the chicken's tailbone. The measuring member 20 and the positioning member 10 are detachably assembled via the connecting portion 11. The measuring member 20 extends along a second direction to form a measuring area 21, and the plane containing the second direction intersects with the plane containing the first direction.

[0040] It should be noted that the first direction and the second direction here are two different directions. The angle formed by the intersection of the plane containing the second direction and the plane containing the first direction can be less than 90 degrees, greater than 90 degrees, or 90 degrees (i.e., perpendicular to each other), depending on the specific needs. For example, refer to... Figure 1-2 As shown, the first direction is the Y direction, the second direction is the X direction, and the angle formed by the intersection of the plane containing the second direction X and the plane containing the first direction Y is 90 degrees.

[0041] The measuring area 21 has a labeling system 22, which is used to directly read the measurement dimensions of the chicken's tail feathers when the fixing part 12 is fixed to the chicken's tailbone.

[0042] Chicken tail feathers refer to the feathers on a chicken's tail. Tail feathers are the primary feathers growing from the chicken's tail, mainly divided into primary tail feathers (central feathers) and lateral tail feathers (including coverts), which together constitute the basic structure of the tail feathers. For example, when the fixing part 12 is fixed to the chicken's pygostyle, the measurement dimensions of the chicken tail feathers are directly read through the labeling system 22. Additionally, image analysis software can be used as needed to simultaneously provide information such as the length, height, and angle of the chicken tail feathers; this disclosure does not limit this aspect.

[0043] The connecting part 11 and the fixing part 12 can be an integral structure or two independent parts connected together; this disclosure does not limit this.

[0044] The measuring element 20 and the positioning element 10 are detachably assembled via the connecting part 11. For example, the detachable assembly can be a snap-fit ​​connection or a threaded connection, and this disclosure does not limit it in this way.

[0045] In use, the measuring component 20 is assembled and fixed with the connecting part 11 of the positioning component 10. During use, the poultry farmer fixes the fixing part 12 of the positioning component 10 to the chicken's tailbone, so that the measuring component 20 and the chicken's tail are relatively fixed. The measurement dimensions of the chicken's tail feathers are directly read through the labeling system 22 of the measuring area 21. Image analysis software can also be used as needed to simultaneously provide information such as the length, height, and angle of the chicken's tail feathers. Compared with the tape measure used in related technologies, the measurement error of chicken tail feathers using this method is smaller for different personnel, saves time and effort, increases measurement speed, and facilitates efficient and accurate measurement of tail feather characteristics by poultry farmers. This improves the breeding efficiency of chicken appearance traits, helps improve the efficiency of poultry farming, and contributes to improving the health level and profitability of poultry farming.

[0046] Figure 4 This is a front view of a positioning element in a chicken tail feather measuring device according to an exemplary embodiment. Figure 5This is a rear view of a positioning element in a chicken tail feather measuring device according to an exemplary embodiment. Figure 8 This is a schematic diagram of the structure of a positioning element in a chicken tail feather measuring device according to an exemplary embodiment.

[0047] In some embodiments, reference Figure 4-5 and Figure 8 As shown, the fixing part 12 is configured as a slotted structure, the slotted structure is provided to penetrate the positioning member 10 along the second direction, one end of the slotted structure is open along the third direction, the third direction is on the same plane as the first direction, and the third direction is different from the first direction.

[0048] The angle between the third direction and the first direction can be less than 90 degrees, greater than 90 degrees, or 90 degrees (i.e., perpendicular to each other), depending on the specific needs. For example, if the first direction is the Y direction and the third direction is the Z direction, the angle between the third direction Z and the first direction Y is 90 degrees.

[0049] In this embodiment, the slotted structure can be a U-shaped slot or a slot of other shapes, as long as the fixing part 12 can be fixed to the chicken's tailbone. When using this method for measurement, the connected measuring element 20 is positioned relatively fixed to the chicken's tail, and the measurement dimensions of the chicken's tail feathers can be directly read through the labeling system 22. For example, the slotted structure is configured as a C-shaped slot, which is adapted to the chicken's tailbone. When using this method for measurement, the fixing part 12 can be fixed to the chicken's tailbone, and the connected measuring element 20 is positioned relatively fixed to the chicken's tail, allowing the measurement dimensions of the chicken's tail feathers to be directly read through the labeling system 22.

[0050] In some embodiments, reference Figure 3-4 and Figure 8 As shown, the connecting part 11 includes a connecting frame 13 and a clamping assembly 14.

[0051] The connecting frame 13 is located on the outer periphery of the positioning member 10, and the connecting frame 13 has an opening on one side along the second direction. The clamping assembly 14 is mounted on the connecting frame 13 and is used to clamp one end of the measuring member 20.

[0052] In this embodiment of the disclosure, the number of connecting brackets 13 can be one or more, and the number of clamping components 14 can be one or more. This embodiment of the disclosure does not limit this, as long as it can ensure that the measuring component 20 and the positioning component 10 can be assembled and fixed.

[0053] In some embodiments, reference Figure 3-4 and Figure 8 As shown, the connecting frame 13 includes: a first side plate 131, a second side plate 132, and a third side plate 133.

[0054] The first side plate 131 is formed on the outer side of the fixing part 12. The second side plate 132 is arranged parallel to and opposite to the first side plate 131. The third side plate 133 is connected to the end of the first side plate 131 and the second side plate 132 on the same side.

[0055] The outer portion of the fixing part 12 defines the first side plate 131. The first side plate 131, the second side plate 132, and the third side plate 133 can be an integral structure or independent components. This embodiment does not limit this.

[0056] It should be noted that the structure of the connecting frame 13 described above is exemplary and is not intended to limit the scope of the connecting frame 13. In this embodiment of the present disclosure, by arranging the second side plate 132 parallel to the first side plate 131, and connecting the third side plate 133 to the ends of the first side plate 131 and the second side plate 132 on the same side, the connecting frame 13 forms a slot for fixing the measuring element 20, thereby facilitating the assembly of the positioning element 10 and the measuring element 20.

[0057] In some embodiments, reference Figure 3-4 and Figure 8 As shown, the third side plate 133 is provided with a limiting slide rail 15 arranged along the first direction, and the clamping assembly 14 includes: a first clamping block 141, a second clamping block 142 and a driving member 143.

[0058] A first clamping block 141 is fixedly mounted on a first side plate 131. A second clamping block 142 is disposed opposite to the first clamping block 141, at least a portion of the second clamping block 142 is adapted to a limiting slide rail 15, and the second clamping block 142 is slidable between the first side plate 131 and the second side plate 132. A driving member 143 has a first end and a second end that are spaced apart from each other along a first direction. The first end is threaded through the second side plate 132 and fixedly connected to the second clamping block 142, and the second end is located on the side of the second side plate 132 away from the first clamping block 141.

[0059] In this embodiment of the present disclosure, by fixing the first clamping block 141 to the first side plate 131, and moving the second clamping block 142 relative to the first clamping block 141 under the action of the driving member 143, the clamping assembly 14 can clamp and fix the measuring member 20, thereby enabling the positioning member 10 and the measuring member 20 to be fixedly assembled.

[0060] In some embodiments, reference Figure 3-5 and Figure 7-8 As shown, the connecting part 11 includes a plurality of connecting parts 11, which are spaced apart on the same side of the positioning member 10.

[0061] For example, there are two connecting parts 11, which are spaced apart on the same side of the positioning member 10. The measuring member 20 and the positioning member 10 can be detachably assembled through the two connecting parts 11, which ensures the stability of the assembly of the measuring member 20 and the positioning member 10.

[0062] For example, there are three connecting parts 11, which are spaced apart on the same side of the positioning member 10. The measuring member 20 and the positioning member 10 can be detachably assembled through the three connecting parts 11, which ensures the stability of the assembly of the measuring member 20 and the positioning member 10.

[0063] In some embodiments, reference Figure 1-5 and Figure 8 As shown, the positioning member 10 also includes a handheld part 16.

[0064] The second area extends along the first direction to form a hand-held part 16, and the hand-held part 16 and the connecting part 11 are located on both sides of the fixing part 12.

[0065] Wherein, the first direction is the Y direction, the hand-held part 16 can be integrally formed with the fixing part 12 and the connecting part 11, or the hand-held part 16 can be an independent component from the fixing part 12 and / or the connecting part 11, and this embodiment does not limit this.

[0066] The hand grip 16 can be made of materials such as rubber, soft rubber, anti-slip patterns or special anti-slip textures, which can provide a firm grip even when hands are sweaty, oily or wearing gloves, prevent slipping and ensure safety.

[0067] In this embodiment of the disclosure, the handheld part 16 is provided to facilitate the operation of the positioning component 10 by the aquaculture personnel, making measurement convenient and thus improving measurement efficiency.

[0068] In some embodiments, reference Figure 1-5 and Figure 8 As shown, the handheld part 16 is configured with an opening, which is provided to penetrate the positioning member 10 along the second direction.

[0069] The second direction is the X direction. The shape of the opening can be a circular hole, an elliptical hole, a rectangular hole, a teardrop-shaped hole, or other irregular geometric shapes, as long as it is convenient for the aquaculture personnel to hold and grasp. This embodiment does not limit this.

[0070] In this embodiment, the opening is rectangular, which facilitates hand gripping by farmers and effectively reduces the overall weight of the positioning component 10. This significantly reduces farmer fatigue, especially for a chicken tail feather measuring device that requires prolonged hand operation.

[0071] Figure 9This is a schematic diagram of the structure of a measuring element in a chicken tail feather measuring device according to an exemplary embodiment.

[0072] In some embodiments, reference Figure 9 As shown, the labeling system 22 includes: a grid region 221 and at least one set of linear scale labels 222.

[0073] Grid region 221 is formed by multiple equally spaced horizontal lines and multiple equally spaced vertical lines intersecting perpendicularly, with the spacing between two adjacent vertical lines equal to the spacing between two adjacent horizontal lines. Linear scale labels 222 extend from the reference mark of grid region 221 along a second direction.

[0074] The second direction is the X direction, and the reference mark is the position formed by the perpendicular intersection of any horizontal and vertical line in grid region 221.

[0075] For example, the spacing between two adjacent horizontal lines is 1.0 cm and the spacing between two adjacent vertical lines is 1.0 cm. Of course, the spacing between two adjacent horizontal lines can also be 0.5 cm, the spacing between two adjacent vertical lines can also be 0.5 cm, or other, and this disclosure does not limit this.

[0076] In this embodiment of the disclosure, the measurement dimensions of the chicken tail feathers to be measured are directly read through the labeling system 22 of the measurement area 21.
