Description

Technical Field

[0001] This invention relates to the field of livestock breeding technology, and in particular to a device and system for measuring the circumference and volume of a bull's scrotum. Background Technology

[0002] In the field of animal husbandry, bull scrotum measurement is a standardized testing technique used in animal husbandry and veterinary medicine to assess the reproductive function of breeding bulls. The core of this technique is to indirectly reflect the development of the testes and the potential for sperm production by quantifying key parameters of the scrotum. It is one of the core indicators for screening bull fertility.

[0003] Existing traditional measurements lack a unified benchmark positioning structure. When manually holding a rangefinder, it is difficult to accurately center the longitudinal and transverse axes of the scrotum. Misjudgments of parameters such as longitudinal diameter and left and right diameter are easily caused by measurement angle deviations. Furthermore, the rangefinder requires continuous manual adjustment. Shaking or changes in force by the operator's hand can cause the contact position between the rangefinder and the scrotum to shift, making it difficult to obtain stable data. Multiple measurements of the same scrotum show significant differences, making it impossible to guarantee the consistency and accuracy of the measurement results.

[0004] Currently, no effective solutions have been proposed for the problems of traditional measurement lacking a reference, unstable handheld rangefinders, and poor data consistency and accuracy in related technologies. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a device and system for measuring the circumference and volume of a bull's scrotum, thereby solving the problems of traditional measurements lacking a reference, unstable handheld rangefinders, and poor data consistency and accuracy.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: In a first aspect, a measuring device for measuring the circumference and volume of a bull's scrotum is provided, comprising: a base unit; A rotating unit is rotatably disposed at the top of the base unit and is used to rotate along the circumference of the base unit; A limiting unit is movably disposed inside the rotating unit and is limitedly connected to the base unit to restrict the rotation of the rotating unit; A vertical orientation unit is slidably disposed at the top of the rotating unit, and is used to reciprocate in the horizontal direction and rotate with the rotating unit; A horizontal adjustment unit is slidably disposed on the vertical orientation unit and is used to reciprocate along the horizontal direction, reciprocate along the height direction of the vertical orientation unit, and follow the movement of the vertical orientation unit; A support unit is slidably disposed at the top of the rotating unit to support the arm and rotate with the rotating unit.

[0007] In some embodiments, the measuring device further includes: A rotation adjustment unit is disposed inside the base unit and connected to the rotation unit, and is used to drive the rotation unit to rotate around the circumference of the base unit; A longitudinal adjustment unit is disposed on the side of the vertical orientation unit and connected to the horizontal adjustment unit, for driving the horizontal adjustment unit to reciprocate along the height direction of the vertical orientation unit; A lateral adjustment unit is disposed on the side of the horizontal adjustment unit and connected to the horizontal adjustment unit, and is used to drive the horizontal adjustment unit to move back and forth in the horizontal direction.

[0008] Secondly, a system for measuring the circumference and volume of a bull's scrotum is provided, comprising: The measuring device as described in the first aspect; A laser device is disposed at the top of the rotating unit of the measuring device, and is used to generate laser light and rotate with the rotating unit; A first ranging device is removably disposed at the end of the horizontal adjustment unit of the measuring device, for measuring the scrotum and moving in accordance with the horizontal adjustment unit; A second ranging device is removably disposed on the side of the horizontal adjustment unit of the measuring device, for measuring the scrotum and moving in accordance with the horizontal adjustment unit.

[0009] The present invention adopts the above technical solution and has the following technical effects compared with the prior art: This invention discloses a measuring device and system for measuring the circumference and volume of a bull's scrotum. The device utilizes the cooperation between a base unit and a rotating unit to achieve a horizontally adjustable rotational effect. The rotating structure of the base unit provides a circumferential rotation trajectory for the rotating unit, ensuring smooth rotation of subsequent units and enabling angle switching, thus avoiding measurement errors caused by angle deviation. A limiting unit provides a locking effect for the rotating unit, which, in conjunction with the base unit and rotating unit, restricts rotation, ensuring a fixed angle during measurement and preventing angle deviation due to device shaking or slight bull movement. The cooperation between a vertical orientation unit and a horizontal adjustment unit provides a stable sliding track and motion constraints for the horizontal adjustment unit, clearly defining its movement direction. This not only limits the horizontal adjustment unit's reciprocating trajectory along the horizontal direction, ensuring it can approach or move away from the scrotum, but also regulates the path of the horizontal adjustment unit's reciprocating movement along the height direction of the vertical orientation unit, preventing deviation or jamming during lifting and lowering. Meanwhile, the horizontal adjustment unit's own structure further enhances the precision of movement and the stability of measurement. Its built-in structure allows for horizontal adjustment, and combined with the guiding constraint of the vertical orientation unit, it controls the movement range of the laser rangefinder, ensuring that the laser rangefinder can gradually approach the target measurement point on the scrotum. This combination ensures that when the horizontal adjustment unit moves the laser rangefinder, it can always move smoothly along the preset direction, solving the problem of positional deviation caused by the lack of guidance when manually holding a laser rangefinder. This ensures that the laser rangefinder can stably acquire values, laying the foundation for subsequent measurements of the scrotum's longitudinal diameter, lateral diameter, and anterior-posterior diameter. The support unit provides support for the operator's arm, reducing arm fatigue and tremors caused by prolonged operation, further ensuring the consistency and accuracy of the measurement data.

The laser is activated to adjust the position of the base element 111 so that the laser point it generates is located at the bottom of the scrotum (i.e., the laser point is close to the central axis of the scrotum) for reference; the vertical orientation element 142 is moved so that it moves along the length direction of the first guide element 127 through the third guide element 141, and the horizontal orientation element 151 is moved accordingly through the vertical orientation element 142, thereby causing the first laser rangefinder and the second laser rangefinder to move accordingly (closer or farther away from the scrotum) until they are adjusted to the appropriate position. Move the horizontal orientation element 151 along the height direction of the vertical orientation element 142. The horizontal orientation element 151 drives the first laser rangefinder to slide along the longitudinal direction (major axis) of the scrotum until the first laser rangefinder is located at the top of the scrotum. Start the first laser rangefinder to measure the distance between the first laser rangefinder (top of the scrotum) and the first marking element 144 (i.e., distance a). Then slowly move the first laser rangefinder downward along the top of the scrotum (downward along the height direction of the vertical orientation element 142) until it reaches the bottom of the scrotum, and measure the distance between the first laser rangefinder (bottom of the scrotum) and the first marking element 144 (i.e., distance b). Calculate the straight-line distance between the top and bottom of the scrotum (i.e., ba) using the first laser rangefinder. This is the longitudinal diameter (i.e., major axis) of the scrotum.

[0172] (III) Measurement of the anteroposterior diameter of the scrotum Move the horizontal orientation element 151 so that it moves along the height of the vertical orientation element 142. The horizontal orientation element 151 drives the second laser rangefinder to slide along the longitudinal direction (long axis) of the scrotum until the second laser rangefinder is located in the middle of the long axis of the scrotum. At this time, twist the control element 155 so that it drives the second abutment element 154 to move closer to the first abutment element 143 until the second abutment element 154 abuts against the first abutment element 143, thereby fixing the horizontal orientation element 151. Move the horizontal adjustment element 158 ​​along the length of the third through-slot element 156. The horizontal adjustment element 158 ​​drives the second laser rangefinder to slide along the lateral (minor axis) of the scrotum until it is positioned at the rear end of the scrotum. Start the second laser rangefinder to measure the distance (c) between the second laser rangefinder (rear end of the scrotum) and the second marking element 1513. Then, slowly move the second laser rangefinder from the rear end to the front end of the scrotum (along the length of the third through-slot element 156) until it reaches the front end of the scrotum, and measure the distance (d) between the second laser rangefinder (front end of the scrotum) and the second marking element 1513. Calculate the straight-line distance (dc) between the front and rear ends of the scrotum using the second laser rangefinder; this is the anteroposterior diameter of the scrotum.

[0173] (iv) Measurement of the left and right diameters of the scrotum Rotate the fourth limiting element 131 to move it upward along the axial direction of the first through slot element 123 until the fourth limiting element 131 separates from the corresponding first limiting element 112; rotate the rotating element 121 so that it rotates along the circumference of the first rotating element 114 via the second rotating element 126, and the rotating element 121 drives the horizontal directional element 151 to rotate accordingly via the vertical directional element 142, and drives the second laser rangefinder to rotate accordingly via the horizontal directional element 151 until the second laser rangefinder rotates to the corresponding position (rotates ninety degrees). During the process, the first through slot element 123 corresponds to (is connected to) the corresponding first limiting element 112. The fourth limiting element 131 is rotated so that it moves downward along the axial direction of the first through slot element 123 until it engages with the corresponding first limiting element 112, thereby fixing the rotating element 121. Move the horizontal adjustment element 158 ​​along the length of the third through-slot element 156. The horizontal adjustment element 158 ​​drives the second laser rangefinder to slide laterally (front and back) along the scrotum until it is positioned on the right side of the scrotum. Start the second laser rangefinder to measure the distance between the second laser rangefinder (right side of the scrotum) and the second marking element 1513 (i.e., distance e). Then, slowly move the second laser rangefinder from the right side of the scrotum to the left (along the length of the third through-slot element 156) until it reaches the left side of the scrotum, and measure the distance between the second laser rangefinder (left side of the scrotum) and the second marking element 1513 (i.e., distance f). Calculate the straight-line distance between the left and right sides of the scrotum using the second laser rangefinder (i.e., fe), which is the left-right diameter of the scrotum.

[0174] (v) Calculation of scrotal volume The volume of a bovine scrotum is commonly calculated using the formula for the volume of an ellipsoid, namely V = (4 / 3)πabc (where a, b, and c are half of the longitudinal diameter, anteroposterior diameter, and lateral diameter of the scrotum, respectively). A simplified and practical formula is V≈0.523×longitudinal diameter×anteroposterior diameter×lateral diameter. For example, assuming the bull's scrotum has a longitudinal diameter of 8cm, an anterior-posterior diameter of 5cm, and a lateral diameter of 4cm; substituting into the formula: volume V≈ 0.523×8×5×4=83.68cm³; result: the scrotum volume is approximately 83.7cm³ (rounded to one decimal place, consistent with the precision of practical applications).

[0175] (vi) Calculation of scrotal circumference The circumference is calculated using the formula: C = πd (where d is the maximum transverse diameter). For example, suppose the bull's scrotum has a longitudinal diameter of 8cm, an anterior-posterior diameter of 5cm, and a lateral diameter of 4cm; substituting into the formula: circumference formula C = 3.14 × 5 = 15.7cm; result: the circumference of the scrotum is 15.7cm.

[0176] The advantages of this invention lie in the following: The cooperation between the base unit and the rotating unit provides a horizontal adjustment rotation effect. The rotating structure of the base unit provides a circumferential rotation trajectory for the rotating unit, ensuring smooth rotation of subsequent units and enabling measurement angle switching, thus avoiding measurement errors caused by angle deviation. The limiting unit provides a locking effect for the rotating unit, which, in conjunction with the base unit and the rotating unit, restricts rotation, ensuring a fixed angle during measurement and preventing angle deviation due to device shaking or slight movement of the bull. The cooperation between the vertical orientation unit and the horizontal adjustment unit provides a stable sliding track and motion constraints for the horizontal adjustment unit, clearly defining its movement direction. This not only limits the horizontal adjustment unit's reciprocating movement trajectory along the horizontal direction, ensuring it can approach or move away from the scrotum, but also regulates its reciprocating movement path along the height direction of the vertical orientation unit, preventing deviation or jamming during lifting and lowering. Simultaneously, the structure of the horizontal adjustment unit itself further enhances precise movement and stable measurement. Its built-in structure allows for horizontal adjustment, and combined with the guiding constraints of the vertical orientation unit, it controls the movement amplitude of the laser rangefinder, ensuring that the laser rangefinder can gradually approach the target measurement point on the scrotum. This combination ensures that when the horizontal adjustment unit drives the laser rangefinder, it can always move smoothly along the preset direction, solving the problem of positional deviation caused by the lack of guidance when manually holding a laser rangefinder. This guarantees that the laser rangefinder can stably obtain values, laying the foundation for subsequent measurements of the scrotum's longitudinal diameter, lateral diameter, and anterior-posterior diameter. The support unit provides support for the operator's arm, reducing arm fatigue and shaking caused by prolonged operation, further ensuring the consistency and accuracy of the measurement data.

[0197] like Figure 14 As shown, the lateral adjustment unit 190 includes a fifth rotating element 191 and a lateral driving element 192. The fifth rotating element 191 is rotatably disposed inside the lateral adjustment unit 150 and is used to drive the lateral adjustment unit 150 to reciprocate in the horizontal direction. The lateral driving element 192 is disposed on the side of the lateral adjustment unit 150 and is connected to the fifth rotating element 191, and is used to drive the fifth rotating element 191 to rotate in its own circumference.

[0206] In some of these embodiments, the lateral drive element 192 is a servo motor.

[0207] The method of using this invention is as follows: (a) Preparation The usage method is basically the same as that in Example (I), and will not be repeated here.

[0208] (ii) Measurement of scrotal longitudinal diameter Place the base element 111 in the designated position (below the scrotum); the operator stands on the side of the cow (with the base element 111 in front of the operator), and gently lifts the bottom of the scrotum with one hand; During the process, one hand is placed on the top of the support element 168. At this time, under the action of the arm, the support element 168 is moved downward along the axis of the fifth guide element 163 through the sixth guide element 164, and the elastic element 165 is squeezed to deform it. When adjusting the position of the arm, the arm can be moved to drive the support element 168 to rotate in the circumference of the second guide element 128 through the fourth guide element 161, to rotate in the circumference of the fifth guide element 163 through the sixth guide element 164, and to rotate in the circumference of the third rotating element 166 through the fourth rotating element 167, until it is adjusted to a suitable position. The laser is activated to adjust the position of the base element 111 so that the laser point it generates is located at the bottom of the scrotum (i.e., the laser point is close to the central axis of the scrotum) for reference; the vertical orientation element 142 is moved so that it moves along the length direction of the first guide element 127 via the third guide element 141, thereby driving the horizontal orientation element 151 to move accordingly, thus driving the first laser rangefinder and the second laser rangefinder to move accordingly (closer or farther from the scrotum) until they are adjusted to the appropriate position; the longitudinal drive element 181 is activated so that it drives the horizontal orientation element 151 to move along the height direction of the vertical element 142, thereby driving the first laser rangefinder along the longitudinal direction of the scrotum ( The first laser rangefinder is slid along its long axis until it is positioned at the top of the scrotum. The first laser rangefinder is then activated to measure the distance between the first laser rangefinder (top of the scrotum) and the first marking element 144 (i.e., distance a). Subsequently, the first laser rangefinder is slowly moved by the longitudinal drive element 181 through the horizontal orientation element 151, moving downwards along the top of the scrotum (downwards along the height direction of the vertical orientation element 142) until it reaches the bottom of the scrotum, and the distance between the first laser rangefinder (bottom of the scrotum) and the first marking element 144 is measured (i.e., distance b). The straight-line distance between the top and bottom of the scrotum (i.e., ba) is calculated using the first laser rangefinder; this is the longitudinal diameter (i.e., long axis) of the scrotum.

[0209] (III) Measurement of the anteroposterior diameter of the scrotum Start the longitudinal drive element 181 to drive the horizontal orientation element 151 to move along the height of the vertical orientation element 142. The horizontal orientation element 151 drives the second laser rangefinder to slide along the longitudinal direction (long axis) of the scrotum until the second laser rangefinder is located in the middle of the long axis of the scrotum and the longitudinal drive element 181 stops working, thereby fixing the horizontal orientation element 151. The lateral drive element 192 is activated, causing the fifth rotating element 191 to rotate circumferentially along the second connecting element 1514. The fifth rotating element 191 then moves the horizontal adjustment element 158 ​​along the length of the third through-slot element 156. The horizontal adjustment element 158 ​​then slides the second laser rangefinder along the lateral (short axis) of the scrotum until it is positioned at the rear end of the scrotum. The second laser rangefinder is then activated to measure the distance from the rear end of the scrotum to the second marking element 1513. The distance between the two points is measured (i.e., the distance is c); then the second laser rangefinder is slowly moved by the horizontal drive element 192 through the horizontal adjustment element 158, so that it moves from the rear end of the scrotum to the front end (moves towards the front end along the length direction of the third through slot element 156) until it reaches the front end of the scrotum, and the distance between the second laser rangefinder (front end of the scrotum) and the second marking element 1513 is measured (i.e., the distance is d); the straight-line distance between the front end and the rear end of the scrotum (i.e., dc) is calculated by the second laser rangefinder, which is the anteroposterior diameter of the scrotum.

[0210] (iv) Measurement of the left and right diameters of the scrotum Rotate the fourth limiting element 131 to move it upward along the axial direction of the first through slot element 123 until the fourth limiting element 131 is separated from the corresponding first limiting element 112. The rotary drive element 171 is activated, causing it to rotate along the circumference of the first rotary element 114 via the second rotary element 126. The rotary element 121 then rotates the horizontal orientation element 151 via the vertical orientation element 142, which in turn rotates the second laser rangefinder. The operation of the rotary drive element 171 is stopped once the second laser rangefinder has rotated to the corresponding position (90 degrees). The lateral drive element 192 is activated, causing the fifth rotating element 191 to rotate circumferentially along the second connecting element 1514. The fifth rotating element 191 then moves the horizontal adjustment element 158 ​​along the length of the third through-slot element 156. The horizontal adjustment element 158 ​​then slides the second laser rangefinder laterally (front and back) along the scrotum until it is positioned on the right side of the scrotum. The second laser rangefinder is then activated to measure the distance from the right side of the scrotum to the second marking element 1513. The distance between the two sides (i.e., the distance is e); then the second laser rangefinder is slowly moved by the horizontal drive element 192 through the horizontal adjustment element 158, so that it moves from the right side of the scrotum to the left side (moves to the left side along the length direction of the third through slot element 156) until it moves to the left side of the scrotum, and the distance between the second laser rangefinder (left side of the scrotum) and the second marking element 1513 is measured (i.e., the distance is f); the straight-line distance between the left side and the right side of the scrotum (i.e., fe) is calculated by the second laser rangefinder, which is the left-right diameter of the scrotum.

[0211] (v) Calculation of scrotal volume The usage method is basically the same as that in Example (V), and will not be repeated here.

[0212] (vi) Calculation of scrotal circumference The usage method is basically the same as that in Example (VI), and will not be repeated here.

[0213] The advantages of this invention lie in the fact that the cooperation between the rotary adjustment unit, the longitudinal adjustment unit, and the lateral adjustment unit achieves a contactless measurement effect, eliminating the need for manual contact with the adjustment components. Measurement angle switching and movement are achieved through drive linkage. Working together, they can sequentially measure the longitudinal diameter, front-rear diameter, and left-right diameter according to a preset program, reducing manual intervention and improving measurement efficiency, thus adapting to the batch testing needs of large-scale aquaculture scenarios.
