Description

Technical Field

[0001] This invention relates to the field of animal husbandry technology, specifically a mobile restraint frame for artificial insemination of yaks used in summer pastures in pastoral areas. Background Technology

[0002] Yaks are highly adaptable to the harsh ecological conditions of high-altitude grasslands, making full use of pasture resources. They are hardy and resilient, thriving and reproducing even in harsh environments with thin air, cold temperatures, and short growing seasons. Artificial insemination of yaks is a core technology for improving breeding efficiency and the quality of the yak population. It requires strict adherence to the process of "estrus detection → semen processing → restraint and insemination → post-operative management," taking into account the yak's high-altitude adaptability, aggressive temperament, and short estrus period. The dosage of insemination for female yaks is determined based on their physical condition. Artificial insemination of female yaks requires equipment such as frozen semen thawing devices and insemination guns, which must be mounted on the yak's restraint frame for successful insemination.

[0003] For example, Chinese Patent Publication No. CN221556126U discloses a restraint frame for artificial insemination, which includes a base and a restraint frame body for restraining livestock. A lifting mechanism is provided between the base and the restraint frame body for driving the restraint frame body to move up and down. The lifting mechanism drives the restraint frame body to move up and down, thereby facilitating the operator to perform artificial insemination on livestock of different heights. Furthermore, the lifting mechanism can be selectively opened to ensure that the semen does not leak out after the livestock is inseminated, and it is also more convenient for the operator to operate.

[0004] In existing technical references, the restraint frame can be raised and lowered using a lifting mechanism to adjust the height of the livestock for artificial insemination. However, the restraint frame itself is not easy to adjust in angle, resulting in the livestock always standing horizontally. The livestock's buttocks are not easy to raise, and they are easily affected by the physiological curvature of the cervix and uterus of the female yak. ​​This not only makes artificial insemination inconvenient, but also makes it difficult for the semen to flow back due to gravity, affecting the success rate of artificial insemination. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention is implemented through the following technical solution: A portable restraint frame for artificial insemination of yaks in summer pastures includes: The frame, and the artificial insemination mechanism mounted on the surface of the frame; The frame includes a support frame, an adjustment component, and a load-bearing component. The load-bearing component is mounted on the bottom of the support frame, and the adjustment component is mounted on the surface of the load-bearing component. Self-locking rollers are installed on the side of the bottom of the support frame. The rolling of the self-locking rollers can move the yak artificial insemination restraint frame to a designated location in the pastoral area and lock the self-locking rollers, making the yak artificial insemination restraint frame more stable as a whole. The adjusting assembly includes a support plate and a hydraulic cylinder. The support plate is mounted on the side of the surface of the supporting assembly. The bottom of the hydraulic cylinder is located near the support plate, and the telescopic end of the hydraulic cylinder is hinged to the bottom of the support plate. A linear actuator is fixedly mounted on the top side of the support plate. A frame is fixedly mounted on the output ends of both sides of the linear actuator. A strip of elastic fabric is fixedly mounted on the bottom of the frame surface. By tilting the support plate at an angle between 15 and 25 degrees, the operation of the hydraulic cylinder can be paused, allowing the support plate to be tilted. Compared to existing technologies where the angle cannot be adjusted and the mother yak remains horizontal, making artificial insemination difficult, this new technology uses the mother yak's hind kicks to step on the top of the support, causing her to tilt. This not only makes the angle of the mother yak's reproductive tract more gentle, preventing the semen from flowing back due to gravity, but also allows it to settle more fully in the target location of the uterine horn or uterine body, increasing the probability of sperm and egg fertilization. Furthermore, the mother yak's hindquarters are raised, and her vaginal opening faces diagonally upwards, which is beneficial for artificial insemination. The artificial insemination mechanism includes a hinged mounting strip and a linear actuator. The hinged mounting strip is fixedly installed on the side of the support frame surface, and the linear actuator is fixedly installed on the surface of the hinged mounting strip. A strip-shaped guide rail is fixedly installed at the output end of the linear actuator. An insemination gun is slidably mounted on the surface of the strip-shaped guide rail. An electric telescopic rod is fixedly installed at the bottom of the strip-shaped guide rail. A limit plate is fixedly installed at the telescopic end of the electric telescopic rod. The output end of the linear actuator drives the strip-shaped guide rail to move, thereby adjusting the height of the insemination gun so that the outlet of the insemination gun is aligned with the vaginal opening of the female yak. ​​Guided by the strip-shaped guide rail, the insemination gun slides towards the vaginal opening of the female yak, passing the insemination cannula at the end of the insemination gun through the vagina and cervix of the female yak, directly delivering diluted and thawed fresh semen into the uterus. The male yak's semen is then injected into the female yak through the insemination gun, thus performing artificial insemination on the female yak.

[0006] Preferably, there are four self-locking rollers, and the four self-locking rollers are evenly distributed on the side of the bottom of the support frame.

[0007] Preferably, the hydraulic cylinders are installed at an angle, there are two hydraulic cylinders, and the two hydraulic cylinders are symmetrically installed along the central axis in the middle of the support plate, and the surface of the strip elastic cloth is a wavy curved surface.

[0008] Preferably, the lead screw linear actuator is installed vertically, and there are two lead screw linear actuators installed symmetrically along the central axis of the support frame. By attaching the strip elastic cloth to the belly of the mother yak, the belly of the mother yak can be lifted and the movement of the output end of the lead screw linear actuator can be paused. This can stabilize the body position of the mother yak and protect the sensitive parts of the mother yak's abdominal organs and uterus, reducing the stress response caused by external pressure. After the artificial insemination of the female yak is completed, the output end of the linear actuator drives the frame to move downward, causing the strip elastic cloth to move downward along with the frame. When the strip elastic cloth moves to the bottom and fits against the top of the support plate, the support of the strip elastic cloth on the female yak's belly is released.

[0009] Preferably, the bearing assembly includes a support base, which is fixedly installed at the middle of the bottom of the support frame. The side of the support plate surface is hinged to the notch on the support base surface. The bottom end of the hydraulic cylinder is hinged to the inner side of the notch on the support base surface. A pedal-type pressure sensor is installed at the middle of the top of the support base. A controller is installed at the top of the support base near the pedal-type pressure sensor.

[0010] Preferably, the pedal-type pressure sensor is electrically connected to the controller, and the support base is horizontally installed.

[0011] Preferably, the linear mover is installed vertically, the strip guide rail is installed horizontally, the electric telescopic rod is installed directly below the insemination gun, and the limiting plate is installed at an angle.

[0012] Preferably, an attraction component is installed on the surface of the support frame near the controller. The attraction component includes a feeding trough and a protective frame. The feeding trough is fixedly installed on the surface of the support frame near one end of the pedal-type pressure sensor. The protective frame is detachably fixedly installed on the top of the support base near the controller. A rectangular box is fixedly installed on the side of the feeding trough. A T-junction pipe is connected to the bottom of the rectangular box. A fan is fixedly installed on the side of the inner side of the protective frame. The air outlet of the fan is connected to a bent pipe. The air outlet at the top of the bent pipe is connected to the air inlet at the bottom of the T-junction pipe. A square frame is installed inside the rectangular box. An odor fabric is fixedly installed in the inner cavity of the square frame. An air nozzle is installed on the surface of the rectangular box near the support frame. The attraction is then conducted using the mother yak. The yak's forehooves step on the pedal-type pressure sensor, causing it to register pressure. The sensor detects that the restraint frame has entered the yak and transmits this information as an electrical signal to the controller. The controller receives and processes this signal, and, in conjunction with the electrical connection between the fan and the controller, automatically activates the fan. The fan's force propels airflow into the bend in the pipe, and through the T-junction, it reaches the interior of the rectangular box. The scent fabric, imbued with the male yak's aroma, is then blown out from the nozzles. This attracts the attention of female yaks in heat, diverting their agitation caused by estrus.

[0013] Preferably, the controller is installed inside the protective frame, which protects the controller from damage, and the fan is electrically connected to the controller.

[0014] The spices are stored in the feeding trough. The aroma of the spices can initially attract female yaks that need artificial insemination, which helps the female yaks to enter the support frame and reduces the irritability caused by the female yak hormones.

[0015] Preferably, there are two rectangular boxes, and the two rectangular boxes are symmetrically installed along the feeding trough. The scent cloth is evenly distributed in the inner cavity of the square frame. By using the limiting plate to hold the female yak's thigh, the insemination gun can be made more stable and shaken less through the support of the limiting plate.

[0016] This invention provides a mobile restraint frame for artificial insemination of yaks in summer pastures. It has the following beneficial effects: I. In the summer pastures of this pastoral area, a mobile yak artificial insemination restraint frame is used. Utilizing a tilted platform, unlike existing technologies where the angle cannot be adjusted and the mother yak remains horizontal, making artificial insemination difficult, the mother yak's hind legs kick the top of the platform, tilting her overall position. This not only makes the angle of the mother yak's reproductive tract smoother, preventing backflow of semen due to gravity, but also allows for more complete deposition in the target location of the uterine horn or uterine body, increasing the probability of sperm and egg fertilization. Furthermore, the mother yak's hindquarters are raised, and her vaginal opening faces upwards at an angle, which is beneficial for artificial insemination.

[0017] Second, in the summer pastures of this pastoral area, a movable yak artificial insemination restraint frame is used. By attaching a strip of elastic cloth to the belly of the female yak, the belly can be lifted to stabilize the female yak's body position and protect the sensitive parts of the female yak's abdominal organs and uterus, reducing the stress response caused by external pressure.

[0018] Third, in the summer pastures of this pastoral area, a mobile yak artificial insemination restraint frame is used. Guided by a strip rail, the insemination gun slides towards the vaginal opening of the female yak. ​​The insemination cannula at the end of the insemination gun passes through the vagina and cervix of the female yak, directly delivering diluted and thawed fresh semen into the uterus. The semen of the male yak is then injected into the female yak through the insemination gun, thus enabling artificial insemination of the female yak.

[0019] IV. In the summer pastures of this pastoral area, a mobile yak artificial insemination restraint frame is used. The blowing power of the fan allows airflow to enter the curved pipe, and under the transmission of the T-junction, the airflow is blown into the interior of the rectangular box. The scent cloth, which is coated with the scent of male yaks, is blown out from the nozzle. When the female yak smells the scent of the male yak, it attracts the attention of the female yak in heat and distracts her from the restlessness caused by estrus.

[0020] Fifth, in the summer pastures of this pastoral area, a mobile yak artificial insemination restraint frame is used. The spice storage trough utilizes the aroma of spices, which can initially attract female yaks that need artificial insemination, helping them to enter the support frame and reducing the irritability caused by the influence of yak hormones.

[0023] 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.

[0024] For the first embodiment, please refer to... Figure 1-5 The present invention provides a technical solution: A portable restraint frame for artificial insemination of yaks in summer pastures includes: The frame 1, and the artificial insemination mechanism 2 mounted on the surface of the frame 1; The frame 1 includes a support frame 11, an adjustment component 12, and a load-bearing component 13. The load-bearing component 13 is installed at the bottom of the support frame 11, and the adjustment component 12 is installed on the surface of the load-bearing component 13. Self-locking rollers 14 are installed on the side of the bottom of the support frame 11. The rolling of the self-locking rollers 14 can move the yak artificial insemination restraint frame to a designated location in the pastoral area and lock the self-locking rollers 14, making the yak artificial insemination restraint frame more stable. There are four self-locking rollers 14, and the four self-locking rollers 14 are evenly distributed on the side of the bottom of the support frame 11.

[0025] The adjusting assembly 12 includes a support plate 121 and a hydraulic cylinder 122. The support plate 121 is mounted on the side of the surface of the supporting assembly 13. The bottom of the hydraulic cylinder 122 is located near the support plate 121. The telescopic end of the hydraulic cylinder 122 is hinged to the bottom of the support plate 121. A linear actuator 123 is fixedly mounted on the top side of the support plate 121. A frame 124 is fixedly mounted on the output ends on both sides of the surface of the linear actuator 123. A strip of elastic fabric 125 is fixedly mounted on the bottom of the surface of the frame 124. The support base 131 supports the support plate 121 and the hydraulic cylinder 122, and the hydraulic cylinder 122 is activated to work. By extending the telescopic end of the hydraulic cylinder 122, an upward pushing force can be applied to the support plate 121. Combined with the hinged installation between the support plate 121 and the notch on the surface of the support base 131, the support plate 121 rotates counterclockwise to adjust the angle after being pushed. The tilt angle of the support plate 121 is between 15 and 25 degrees. The hydraulic cylinder 122 can be paused during the operation, causing the support plate 121 to be tilted. Compared with the existing technology where the angle cannot be adjusted and the mother yak always stands horizontally, making it inconvenient to perform artificial insemination, the mother yak's hind kicks on the top of the support plate 121, causing the mother yak to be tilted. This not only makes the angle of the mother yak's reproductive tract more gentle, but also prevents the semen introduced for artificial insemination from flowing back due to gravity, allowing it to be deposited more fully in the target position of the uterine horn or uterine body, increasing the probability of sperm and egg fertilization. Moreover, the mother yak's buttocks are raised, and the mother yak's vaginal opening faces diagonally upward, which is conducive to artificial insemination. After the mother yak is artificially inseminated, the staff can restart the hydraulic cylinder 122. Through the contraction of the extension end of the hydraulic cylinder 122, a downward pulling force can be applied to the support plate 121, causing the support plate 121 to rotate clockwise until the support plate 121 is flush with the support base 131, making it easier for the mother yak to be pulled out of the restraint frame. The hydraulic cylinder 122 is installed at an angle. There are two hydraulic cylinders 122, and the two hydraulic cylinders 122 are symmetrically installed along the central axis in the middle of the support plate 121. The surface of the strip elastic cloth 125 is a wavy curved surface.

[0026] Once the female yak requiring artificial insemination is placed inside the support frame 11, the linear actuator 123 is activated. The output of the linear actuator 123 moves the frame 124 upwards, causing the elastic fabric strip 125 to move upwards along with the frame 124. This brings the elastic fabric strip 125 closer to the yak's belly, supporting it by ensuring it is in contact with the yak's abdomen. The movement of the linear actuator 123's output is then paused, stabilizing the yak. The system is positioned to protect the sensitive areas of the female yak's abdominal organs and uterus, reducing stress caused by external pressure. After artificial insemination of the female yak, the linear actuator 123 is activated again. The output end of the linear actuator 123 drives the frame 124 to move downward, causing the strip elastic cloth 125 to move downward along with the frame 124. When the strip elastic cloth 125 is at its lowest point, it fits against the top of the support plate 121, thus releasing the support of the strip elastic cloth 125 on the female yak's belly.

[0027] The lead screw linear actuator 123 is installed vertically. There are two lead screw linear actuators 123, and the two lead screw linear actuators 123 are installed symmetrically along the central axis in the middle of the support frame 11.

[0028] The support assembly 13 includes a support base 131, which is fixedly installed at the middle of the bottom of the support frame 11. The side of the surface of the support plate 121 is hinged to the notch on the surface of the support base 131. The bottom end of the hydraulic cylinder 122 is hinged to the inner side of the notch on the surface of the support base 131. A pedal-type pressure sensor 132 is installed at the middle of the top of the support base 131. A controller 133 is installed at the top of the support base 131 and near the pedal-type pressure sensor 132.

[0029] The pedal-type pressure sensor 132 is electrically connected to the controller 133, and the support base 131 is installed horizontally.

[0030] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 1 to 7 As shown: The artificial insemination mechanism 2 includes a hinged mounting strip 21 and a linear actuator 22. The hinged mounting strip 21 is fixedly mounted on the side of the support frame 11. The linear actuator 22 is fixedly mounted on the surface of the hinged mounting strip 21. A strip guide rail 23 is fixedly mounted at the output end of the linear actuator 22. An insemination gun 24 is slidably mounted on the surface of the strip guide rail 23. An electric telescopic rod 25 is fixedly mounted at the bottom of the strip guide rail 23. A limit plate 26 is fixedly mounted at the telescopic end of the electric telescopic rod 25. The operator places the thawed sperm storage tube into the insemination gun 24 and activates the linear actuator. The linear actuator 22 operates by moving the linear guide rail 23 via its output end, thereby adjusting the height of the insemination gun 24 so that its outlet is aligned with the vaginal opening of the female yak. ​​Guided by the linear guide rail 23, the insemination gun 24 slides towards the vaginal opening of the female yak, allowing the insemination cannula at the end of the insemination gun 24 to pass through the vagina and cervix of the female yak. ​​This directly delivers diluted and thawed fresh semen into the uterus, and the male yak's semen is injected into the female yak through the insemination gun 24, thus performing artificial insemination on the female yak.

[0031] The linear mover 22 is installed vertically, the strip rail 23 is installed horizontally, the electric telescopic rod 25 is installed directly below the insemination gun 24, and the limit plate 26 is installed at an angle.

[0032] The third embodiment is based on the first and second embodiments; please refer to [link / reference]. Figures 1 to 9 As shown: An induction assembly 3 is installed on the surface of the support frame 11 near the controller 133. The induction assembly 3 includes a feeding trough 31 and a protective frame 32. The feeding trough 31 is fixedly installed on the surface of the support frame 11 near one end of the pedal-type pressure sensor 132. The protective frame 32 is detachably fixedly installed on the top of the support base 131 near the controller 133. A rectangular box 33 is fixedly installed on the side of the surface of the feeding trough 31. A three-way pipe 34 is connected to the bottom of the rectangular box 33. A fan 35 is fixedly installed on the side of the inner side of the protective frame 32. The air outlet of 5 is connected to a bent pipe 36. The air outlet at the top of the bent pipe 36 is connected to the air inlet at the bottom of the three-way pipe 34. A square frame 37 is installed inside the rectangular box 33. The inner cavity of the square frame 37 is fixedly installed with scent cloth 38. An air nozzle 39 is installed on the surface of the rectangular box 33 and on the side near the support frame 11. Spices that female yaks like to eat are put into the feeding trough 31. By using the storage of spices in the feeding trough 31, the aroma of the spices can be released, which can initially attract female yaks that need artificial insemination and help the female yaks enter the interior of the support frame 11.

[0033] The controller 133 is installed inside the protective frame 32, which protects the controller 133 from damage. The fan 35 is electrically connected to the controller 133.

[0034] Initially, the hydraulic cylinder 122 retracts, and the support plate 121 is horizontal. The female yak requiring artificial insemination walks across the support plate 121, and its front hooves step on the pedal-type pressure sensor 132, causing pressure on the sensor. The pedal-type pressure sensor 132 detects that the restraint frame has entered the yak and transmits the collected information as an electrical signal to the controller 133. The controller 133 receives and processes the electrical signal emitted by the pedal-type pressure sensor 132. The system, in conjunction with the electrical connection between the fan 35 and the controller 133, enables the controller 133 to control the fan 35, automatically turning it on. The fan 35's blowing force causes airflow to enter the bent pipe 36, and under the transmission of the three-way pipe 34, the airflow is blown into the interior of the rectangular box 33. The scent cloth 38, which is coated with the scent of male yaks, is blown out from the nozzle 39, attracting the female yaks after they smell the scent of male yaks, attracting their attention, and distracting them from the restlessness caused by estrus.

[0035] There are two rectangular boxes 33, and the two rectangular boxes 33 are symmetrically installed along the feeding trough 31. The odor cloth 38 is evenly distributed in the inner cavity of the square frame 37. By extending the telescopic end of the electric telescopic rod 25, the telescopic end of the electric telescopic rod 25 applies a pushing force to the limiting plate 26, causing the limiting plate 26 to move closer to the thigh of the mother yak. ​​The limiting plate 26 is locked at the thigh of the mother yak, and the extension of the telescopic end of the electric telescopic rod 25 is stopped, and the movement of the limiting plate 26 is stopped.

[0036] In use, the yak artificial insemination restraint frame can first be moved to the designated location in the pastoral area by the rolling of the self-locking roller 14, and the self-locking roller 14 can be self-locked to make the yak artificial insemination restraint frame more stable. Then, the square frame 37 and the scent cloth 38 are coated with the scent of male yaks, and the cover plate on the surface of the rectangular box 33 is opened. The scent cloth 38 coated with the scent of male yaks and the square frame 37 are placed inside the rectangular box 33, and spices are placed in the feeding trough 31. At this time, by using the hinged mounting strip 21 to hinge the support frame 11, the artificial insemination mechanism 2 can be rotated as a whole toward the yak inlet, away from the surface of the support frame 11. Furthermore, by placing spices that female yaks love to eat in the feeding trough 31, the trough 31 stores the spices, and the aroma of the spices wafts out. When female yaks in heat smell the aroma of the spices, they can be initially attracted to female yaks that need artificial insemination. Initially, the hydraulic cylinder 122 retracts, and the support plate 121 is horizontal. The female yak requiring artificial insemination walks across the support plate 121, and its front hooves step on the pedal-type pressure sensor 132, causing pressure on the sensor. The pedal-type pressure sensor 132 detects that the restraint frame has entered the yak and transmits the collected information as an electrical signal to the controller 133. The controller 133 receives and processes the electrical signal emitted by the pedal-type pressure sensor 132. The system works by connecting the blower 35 to the controller 133 via electrical connection, which allows the controller 133 to control the blower 35 and automatically turn it on. The blower 35 then directs the airflow into the bent pipe 36 and through the three-way pipe 34, it blows the airflow into the rectangular box 33. The scent cloth 38, which is coated with the scent of male yaks, is blown out from the nozzle 39. This attracts the female yaks to the scent of male yaks, distracting them from the irritation caused by estrus. Simultaneously, the linear actuator 123 is electrically connected to the controller 133. The pedal-type pressure sensor 132 is subjected to the trampling pressure of the mother yak's front hoof. After detecting the presence of a yak, the controller 133 controls the linear actuator 123 to automatically start working. The output end of the linear actuator 123 drives the frame 124 to move upward, causing the strip elastic cloth 125 to move upward with the frame 124. This causes the strip elastic cloth 125 to move closer to the mother yak's belly. By making the strip elastic cloth 125 fit against the mother yak's belly, the mother yak's belly can be supported, and the movement of the output end of the linear actuator 123 can be paused. This can stabilize the mother yak's body position and protect the sensitive parts of the mother yak's abdominal organs and uterus, reducing the stress response caused by external pressure. Furthermore, the support base 131 supports the pallet 121 and the hydraulic cylinder 122. The hydraulic cylinder 122 is electrically connected to the controller 133 via a solenoid valve. When the pedal-type pressure sensor 132 detects the presence of a yak by the pressure of its front hoof, the controller 133 controls the hydraulic cylinder 122, activating it to operate. The extension of the hydraulic cylinder 122's telescopic end applies an upward pushing force to the pallet 121. Combined with the hinged installation between the pallet 121 and the notch on the surface of the support base 131, the pallet 121 rotates counterclockwise to adjust its angle after receiving the pushing force. When the tilt angle is between 15 and 25 degrees, the hydraulic cylinder 122 can be paused, so that the support plate 121 is in a tilted state. Compared with the existing technology where the angle cannot be adjusted, the mother yak always stands horizontally, which is inconvenient for artificial insemination. When the mother yak kicks on the top of the support plate 121, the mother yak is tilted. This not only makes the angle of the mother yak's reproductive tract more gentle, but also makes the semen introduced by artificial insemination less likely to flow back due to gravity. It can be more fully deposited in the target position of the uterine horn or uterine body, increasing the probability of sperm and egg fusion. In addition, the mother yak's buttocks are lifted, and the mother yak's vaginal opening faces diagonally upward. Furthermore, the staff places the thawed semen collection tube into the insemination gun 24 and activates the linear actuator 22. The output end of the linear actuator 22 drives the strip guide 23 to move, adjusting the height of the insemination gun 24 so that the semen outlet of the insemination gun 24 is aligned with the vaginal opening of the female yak. ​​Under the hinged installation of the hinged mounting strip 21, the insemination gun 24 is rotated in the opposite direction, moving closer to the vaginal opening of the female yak. ​​Guided by the strip guide 23, the insemination gun 24 slides towards the vaginal opening of the female yak, passing the insemination catheter at the end of the insemination gun 24 through the vagina and cervix of the female yak, directly delivering the diluted and thawed fresh semen into the uterus. The male yak's semen is then injected into the female yak through the insemination gun 24, thus performing artificial insemination on the female yak. Furthermore, the electric telescopic rod 25 is electrically connected to the controller 133. When the pedal-type pressure sensor 132 detects the presence of a yak by the pressure of the wooden yak's front hoof, the controller 133 controls the electric telescopic rod 25. By extending the telescopic end of the electric telescopic rod 25, the telescopic end of the electric telescopic rod 25 applies a pushing force to the limiting plate 26, causing the limiting plate 26 to move closer to the thigh of the female yak. ​​By using the limiting plate 26 to lock in the position of the female yak's thigh, the extension of the telescopic end of the electric telescopic rod 25 is stopped, and the movement of the limiting plate 26 is also stopped. With the support and assistance of the limiting plate 26, the insemination gun 24 can be made more stable and the shaking is reduced. After the artificial insemination of the female yak is completed, the staff rotates the artificial insemination mechanism 2 in the reverse direction to open the entrance and exit of the support frame 11 and retract the telescopic end of the electric telescopic rod 25. The telescopic end of the electric telescopic rod 25 drives the limit plate 26 to move away from the thigh of the female yak. ​​At the same time, the telescopic end of the electric telescopic rod 25 retracts, and transmits the information of this retraction action to the controller 133 in the form of an electrical signal. The controller 133 receives and processes the information and determines that the female yak and artificial insemination are completed. At this time, the controller 133 first controls the lead screw linear actuator 123, which drives the frame 124 to move downward through the output end of the lead screw linear actuator 123. This causes the strip elastic cloth 125 to move downward along with the frame 124, so that the strip elastic cloth 125 moves to the bottom and fits against the top of the support plate 121. This releases the strip elastic cloth 125 from supporting the mother yak's belly. Then, the controller 133 controls the hydraulic cylinder 122. By contracting the extension end of the hydraulic cylinder 122, a downward pulling force can be applied to the support plate 121, causing the support plate 121 to rotate clockwise until the support plate 121 is flush with the support base 131, making it easier for the mother yak to step out of the restraint frame. Finally, the fan 35 is controlled by the controller 133 to stop working.
