[0002] In modern animal husbandry, artificial insemination technology is widely used in livestock breeding management as a key means to improve reproductive efficiency. The core of this technology is to accurately deliver selected and processed semen into the uterus of female animals in estrus through delicate operations to promote the fertilization process, thereby improving genetic quality and production efficiency. However, traditional artificial insemination methods, especially when insemination is performed by manually operated injection devices, have certain challenges and limitations.

[0003] During the insemination process, the insertion of the injection device often stimulates the sensitive female animals, triggering a series of physiological and behavioral reactions, the most typical of which is the violent struggle of the animals.

DETAILED DESCRIPTION

[0018] In order to more clearly illustrate the technical solution of the embodiment of the present invention, the drawings of the embodiment will be briefly introduced below. Obviously, the drawings in the following description only involve some embodiments of the present invention, but not limit the present invention. The first power member 15 and the second power member 3 are both electric push rods, and the third power member 4 is a servo motor.

[0019] Research has found that when using an injection device to perform artificial insemination on a sow, the action of inserting the injection device into the sow's uterus stimulates the sensitive sow, causing the sow to struggle violently and easily causing the injection device to fall out of the sow's uterus, affecting the effect of artificial insemination.

[0020] Embodiment 1: An artificial insemination device for sows, such as Figure 1-Figure 4As shown, it includes a workbench 1, two first support plates 11 symmetrically connected to the middle of the workbench 1, inclined slopes are provided on the left and right sides of the workbench 1, a control terminal 111 is installed on the front side of the workbench 1, a frame 12 is fixed to the middle of the upper surface of the workbench 1, a switch door 13 is installed on the right side of the frame 12, a first sliding plate 14 is slidably provided on the left side of the frame 12, a first power member 15 electrically connected to the control terminal 111 is embedded in the front of the workbench 1, the telescopic end of the first power member 15 is fixed to the front side of the first sliding plate 14, a material storage shell 16 is fixed to the left side of the first sliding plate 14 through a bracket, a material storage shell 16 is provided at the lower part of the material storage shell 16 with a material injection port for installing a one-way valve, the one-way valve in the material injection port on the material storage shell 16 is used to limit the outflow of semen therefrom, a sliding push plate 17 is slidably provided on the upper part of the material storage shell 16, and the material storage shell 1 The lower side of 6 is connected to an injection pipe 18 through a hose, and a one-way valve is installed in the hose of the storage shell 16. The one-way valve on the hose is used for the semen in the storage shell 16 to flow into the injection pipe 18. Two left-right symmetrical rotating rollers are rotatably arranged in the middle of the workbench 1, and two front-to-back symmetrical belts 2 are wound between the two rotating rollers on the workbench 1. The first support plate 11 is in contact with the adjacent belts 2, and the upper part of the first support plate 11 is rotatably arranged with a roller for reducing the friction between it and the adjacent belts 2. A fixing mechanism for pressing the animal to be inseminated is installed on the workbench 1. The stability of the artificial insemination operation is improved by the restriction of the frame 12 and the unloading of the two belts 2. At the same time, the hose between the storage shell 16 and the injection pipe 18 can effectively prevent the injection pipe 18 from detaching from the sow's uterus during the sow's struggle, thereby improving the stability of semen injection into the sow's uterus.

[0021] like Figure 3As shown, the fixing mechanism includes a second power member 3 electrically connected to the control terminal 111, the second power member 3 is fixedly connected to the workbench 1, a first telescopic rod 31 is fixedly connected to the upper surface of the workbench 1, the first telescopic rod 31 is located between the two first support plates 11, a connecting plate 32 is installed between the telescopic end of the first telescopic rod 31 and the telescopic end of the second power member 3, a support frame 33 is slidably provided on the upper part of the connecting plate 32, two left-right symmetrical springs are installed between the support frame 33 and the connecting plate 32, two second telescopic rods 34 symmetrically connected to the upper surface of the workbench 1 are fixedly connected to the upper surface of the workbench 1, and the two second telescopic rods 34 are respectively located at the front and rear ends of the frame 12 On the other hand, the cavities of the two second telescopic rods 34 are connected to the cavity of the first telescopic rod 31 through pipes, and the cavities of the two second telescopic rods 34, the cavity of the first telescopic rod 31 and the pipes connected thereto are all filled with liquid. The telescopic ends of the two second telescopic rods 34 are commonly fixedly connected to a connecting frame 35, and a pressure plate frame 36 is slidably provided in the middle of the connecting frame 35. The pressure plate frame 36 penetrates the frame 12 and is slidably connected thereto, and a spring is installed between the pressure plate frame 36 and the connecting frame 35. The support plate frame 33 lifts the sow's abdomen and the pressure plate frame 36 presses the sow's back to further restrict the sow's activities, thereby improving the stability of the artificial insemination operation.

[0022] When performing artificial insemination on a sow, the operator first injects a certain amount of semen into the storage shell 16 through the injection port on the storage shell 16, and then the operator starts the first power member 15 through the control terminal 111. The first power member 15 works to make the first sliding plate 14 drive the connected parts to move upward, and then the operator drives the sow into the frame 12. Then the operator controls the first power member 15 through the control terminal 111 to perform the above-mentioned reverse work, so that the first sliding plate 14 moves in the opposite direction and resets.

[0023] After the first sliding plate 14 is reset, the sow is trapped in the frame 12. At this time, the sow steps on the two belts 2. Then the operator starts the second power piece 3 through the control terminal 111. The telescopic end of the second power piece 3 drives the support frame 33 to move upward through the connecting plate 32 and the connected spring. The support frame 33 moves upward to support the abdomen of the sow. The connecting plate 32 simultaneously moves the telescopic end of the first telescopic rod 31 upward. Under the action of the liquid in the chamber of the first telescopic rod 31 and the liquid in the inner chamber of the two second telescopic rods 34, the telescopic end of the first telescopic rod 31 moves through the connected pipe to make the telescopic ends of the two second telescopic rods 34 drive the connecting frame 35 and the pressing plate frame 36 to move downward. After the pressing plate frame 36 moves down and contacts the back of the sow, the second power piece 3 continues to work, compressing the spring connected to the support frame 33 and the pressing plate frame 36, further limiting the sow to prevent the sow from moving around during artificial insemination.

[0024] After the third power part 4 has finished working, the sow is limited. Then the operator holds the injection tube 18 and inserts it into the sow's uterus. The subsequent operator slowly presses the sliding push plate 17, and the sliding push plate 17 moves down to inject the semen in the storage shell 16 into the sow's uterus through the hose and the injection tube 18 to complete the artificial insemination operation of the sow. In this process, the limiting effect of the support plate frame 33 and the pressure plate frame 36 can prevent the sow from breaking free during the artificial insemination process. At the same time, the free rotation of the belt 2 can buffer the movement of the sow's limbs during the struggle, further reducing the degree of the sow's struggle, thereby improving the stability of the sow during artificial insemination and ensuring that the semen is smoothly injected into the sow's uterus.

[0025] After injecting a certain amount of semen into the sow's uterus, the operator pulls out the injection tube 18, and then controls the second power member 3 to perform the above-mentioned reverse work through the control terminal 111, so that the support frame 33 and the pressure plate frame 36 perform the above-mentioned reverse movement and reset, and then the operator opens the switch door 13 to drive the sow out of the frame 12, and then the operator closes the switch door 13 to complete the artificial insemination operation of a single sow, and the above-mentioned operation can be repeated for the artificial insemination operation of the remaining sows.

[0026] Research has found that during the artificial insemination process, due to the influence of artificial semen, the amount of artificially injected semen is not uniform, which affects the sow's absorption efficiency of semen. At the same time, research has found that when the sow is in a state of uterine contraction, the injected semen is easily absorbed in large quantities.

[0027] Embodiment 2: Based on embodiment 1, Figure 1 and Figure 4As shown, it also includes a driving mechanism for controlling the uniform movement of the sliding push plate 17, the driving mechanism is arranged on the first sliding plate 14, the driving mechanism includes a third power member 4 electrically connected to the control terminal 111, the third power member 4 is fixedly connected to the front side of the first sliding plate 14, the output shaft of the third power member 4 is installed with a round table wheel 41, the first sliding plate 14 is rotatably provided with a first rotating shaft 42, the front end of the first rotating shaft 42 is provided with a rotating wheel 43 that cooperates with the round table wheel 41, the left side of the first sliding plate 14 is rotatably provided with a second rotating shaft 44 through a bracket, and the second rotating shaft 44 and the first rotating shaft 42 are connected by a pulley and a transmission Belt drive, a threaded rod 45 is rotatably provided on the left side of the first sliding plate 14 through a bracket, and a bevel gear is fixedly connected to the lower end of the threaded rod 45 and the rear end of the second rotating shaft 44, and the two adjacent bevel gears are meshed with each other. A sliding block 46 that is threadably matched with the threaded rod 45 is slidably provided on the upper part of the sliding push plate 17, and two springs that are symmetrical up and down are installed between the sliding block 46 and the sliding push plate 17. A beating component for beating the animal to be inseminated is provided on the first sliding plate 14, and the operation of the third power member 4 is used to control the sliding push plate 17 to move at a uniform speed, so that the semen in the storage shell 16 is uniformly injected into the sow's uterus through the injection tube 18.

[0028] like Figure 4 and Figure 5 As shown, the beating assembly includes a second support plate 5, the second support plate 5 is fixedly connected to the right side of the first sliding plate 14, the upper part of the second support plate 5 is provided with a second sliding plate 51 for limited sliding sliding, the front part of the second sliding plate 51 is provided with a first limiting column for sliding, the first limiting column is in contact with the second support plate 5, a tension spring is installed between the second sliding plate 51 and the first limiting column thereon, the upper part of the second sliding plate 51 is provided with a limiting groove for the injection tube 18 to pass through, a telescopic shaft 52 is provided between the second support plate 5 and the second sliding plate 51 for common rotation, the two ends of the telescopic shaft 52 are respectively limitedly rotated with the second support plate 5 and the second sliding plate 51, and the telescopic shaft 5 The lower end of the second sliding plate 51 is driven by the first rotating shaft 42 through a bevel gear set, the upper end of the telescopic shaft 52 is fixedly connected with a turntable 53, the upper part of the second sliding plate 51 is slidably provided with a first sliding frame 54, the first sliding frame 54 is provided with a slide groove, the eccentric part of the turntable 53 is provided with a convex column, the convex column of the turntable 53 is slidably matched with the slide groove on the first sliding frame 54, the right part of the first sliding frame 54 is rotatably provided with a swing plate 55, a spring is installed between the swing plate 55 and the first sliding frame 54, the first sliding frame 54 and the swing plate 55 are used to reciprocate to slap the sow, stimulate the sow to contract, improve the efficiency of the sow's uterus in absorbing semen, and increase the chance of sow pregnancy.

[0029] After completing the positioning of the sow, the operator pulls the first limiting column on the second sliding plate 51 and adjusts the height of the second sliding plate 51 so that the injection tube 18 placed in the round hole on the second sliding plate 51 is inserted into the sow's uterus. Then the operator releases the tension on the first limiting column on the second sliding plate 51, and under the action of the tension spring of the first limiting column on the second sliding plate 51, the second sliding plate 51 maintains the adjusted height.

[0030] After the second sliding plate 51 is adjusted, the operator starts the third power member 4 through the control terminal 111. The output shaft of the third power member 4 drives the first rotating shaft 42 to rotate through the truncated cone wheel 41 and the rotating wheel 43. The rotation of the first rotating shaft 42 drives the second rotating shaft 44 to rotate through the pulley and the transmission belt. The rotation of the second rotating shaft 44 drives the threaded rod 45 to rotate stably through the bevel gear set. The rotation of the threaded rod 45 causes the sliding block 46 to move downward at a uniform speed along the thread thereon. The sliding block 46 drives the sliding push plate 17 to move slowly downward, and the semen in the storage shell 16 is uniformly injected into the sow's uterus.

[0031] The first rotating shaft 42 rotates and drives the telescopic shaft 52 and the rotating disk 53 to rotate through the bevel gear set. The rotating disk 53 rotates so that the upper protrusion squeezes the slide groove of the first sliding frame 54, so that the first sliding frame 54 drives the swing plate 55 to move back and forth left and right. The reciprocating movement of the first sliding frame 54 causes the swing plate 55 to reciprocately beat and stimulate the sow, causing the sow to contract its uterus, thereby improving the sow's uterine absorption efficiency of semen, reducing the backflow of semen, and increasing the chance of conception.

[0032] Research has found that during artificial insemination of sows, the sows have a high absorption efficiency of the injected semen when their uterus is in contraction.

In the initial state, the fixed rod 61 supports and limits the second sliding frame 64, so that the first sliding push rod 63 is located at the lower end of the oblique groove on the second sliding frame 64. At this time, the liquid is all located in the fixed shell 62, and the spherical end of the rubber sleeve 6 is flat, which is convenient for the rubber sleeve 6 to be inserted into the sow's uterus.

The third sliding plate 71 contacts the liquid in the chamber of the rubber sleeve 6, and the right part in the injection tube 18 is slidably provided with a first sphere 72 for blocking its own through hole, and a tension spring is installed between the first sphere 72 and the injection tube 18. A conduit 73 is fixedly connected between the second fixed shell 7 and the rubber sleeve 6. The conduit 73 is used to connect the second fixed shell 7 with the outside of the rubber sleeve 6, and the right part in the conduit 73 is slidably provided with a spring for blocking its own through hole. The second sphere 74 of the through hole, a tension spring is installed between the second sphere 74 and the catheter 73, the sliding push plate 17 is slidably provided with a second sliding push rod 75, the lower part of the second sliding push rod 75 is slidably matched with the storage shell 16, and a spring is installed between the second sliding push rod 75 and the sliding push plate 17. The elastic coefficient of the spring between the second sliding push rod 75 and the sliding push plate 17 is smaller than the elastic coefficient of the tension spring between the first sphere 72 and the injection tube 18, and the elastic coefficient of the tension spring between the third sliding plate 71 and the second fixed shell 7 is larger than the elastic coefficient of the tension spring between the first sphere 72 and the injection tube 18. The deformation of the spherical end of the rubber sleeve 6 is used to make the first sphere 72 and the second sphere 74 move back and forth, and the semen in the second fixed shell 7 is injected into the sow's uterus under the sow's contraction state, so as to facilitate the sow's uterus to efficiently absorb the semen.

[0035] After the sow in the frame 12 is limited by the support frame 33 and the pressure plate frame 36, the operator repeats the above operation to adjust the height of the second sliding plate 51. At this time, the spring connected to the second sliding frame 64 is in a compressed state in the initial state. After the height adjustment of the second sliding plate 51 is completed, the operator holds the second sliding frame 64 to keep the second sliding frame 64 in the initial state, even if the first sliding push rod 63 is still at the lower end of the inclined groove on the second sliding frame 64. Then the operator inserts the rubber cover 6 into the sow's uterus. Then the operator releases the second sliding frame 64. Under the elastic force of the spring connected to the second sliding frame 64, the inclined groove on the second sliding frame 64 squeezes the first sliding push rod 63 to move. The first sliding push rod 63 moves to push the liquid in the first fixed shell 62 through the pipeline into the cavity of the rubber cover 6, so that the right end of the rubber cover 6 expands to form a sphere stuck in the sow's uterus.

[0036] After the rubber sleeve 6 is inserted into the sow's uterus, the operator starts the third power member 4 through the control terminal 111. The third power member 4 repeats the above operation to make the sliding push plate 17 move slowly downward. The sliding push plate 17 moves downward and drives the second sliding push rod 75 to move downward together through the connected spring. At this time, due to the blocking effect of the first sphere 72 on the injection tube 18, the spring connected to the sliding push plate 17 is compressed and deformed during the downward movement of the sliding push plate 17, thereby pressurizing the semen in the storage shell 16.

[0037] The third power member 4 works and repeats the above operation to make the first sliding frame 54 and the swing plate 55 move back and forth to slap and stimulate the sow, so that the sow has uterine contraction. The sow's uterine contraction squeezes the spherical part of the rubber sleeve 6. Under the squeezing action, the liquid in the spherical part of the rubber sleeve 6 squeezes the two third sliding plates 71 closer together, and the two third sliding plates 71 move to stretch the connected tension springs. At this time, the two third sliding plates 71 move to squeeze the semen in the second fixed shell 7 into the catheter 73, and the subsequent semen is injected into the second sphere 74. Into the sow's uterus, the semen is injected into the sow's uterus under the state of sow's uterine contraction, further improving the sow's uterus's absorption efficiency of semen. Then the sow's uterus is restored under the tension of the tension spring on the third sliding plate 71. At this time, the second sphere 74 is first retracted into the catheter 73 to achieve the blocking of the catheter 73. Subsequently, due to the adsorption effect during the resetting process of the third sliding plate 71, the semen in the injection tube 18 is injected into the second fixed shell 7 through the first sphere 72. Subsequently, accompanied by the sow's uterine contraction, the semen is slowly and intermittently injected into the sow's uterus.

[0038] When the sow's uterine contraction is poor, the spherical part of the rubber sleeve 6 will not change significantly, that is, the third sliding plate 71 will not move violently at this time. At this time, the sliding push plate 17 slowly moves downward so that the elastic force required by the spring connected to it gradually increases. When the elastic force of the spring connected to the sliding push plate 17 is greater than the tension of the tension spring connected to the first sphere 72, semen is injected into the second fixed shell 7 through the injection tube 18. When the elastic force of the spring connected to the subsequent sliding push plate 17 is greater than the tension of the tension spring on the second sphere 74, semen is injected into the sow's uterus through the catheter 73 to complete the artificial insemination operation.

[0039] After the artificial insemination operation is completed, the operator repeats the above operation to close the third power member 4, and then the operator pulls the second sliding frame 64 to reset, and pulls the rubber cover 6 out of the sow's body, and makes the fixed rod 61 support the second sliding frame 64 again, and then controls the second power member 3 to reset, and opens the switch door 13 to drive the inseminated sow out of the frame 12.

[0040] Research has found that in the process of stimulating sows' uterine contractions to absorb artificially injected semen, if the sows are stimulated too much, it can easily cause the sows' struggle to intensify, affecting the smoothness of semen injection.

[0041] Embodiment 4: Based on the embodiment 3, Figure 2 , Fig. 9 and Fig.10 As shown, it also includes an adjusting mechanism for adjusting the speed of the first rotating shaft 42, the adjusting mechanism is arranged on the first fixed shell 62, the front part of the first rotating shaft 42 is provided with a spline groove, the rotating wheel 43 is located in the spline groove part of the first rotating shaft 42 and slides, the adjusting mechanism includes a third sliding push rod 9, the third sliding push rod 9 is slidably arranged at the front part of the first fixed shell 62, a spring is installed between the third sliding push rod 9 and the first fixed shell 62, the left side of the first sliding plate 14 is fixedly connected to the third fixed shell 91, the rear part of the third fixed shell 91 is slidably arranged with a fourth sliding push rod 92, the fourth sliding push rod 92 is pressed and matched with the third sliding push rod 9, a spring is installed between the fourth sliding push rod 92 and the third fixed shell 91, the front part of the third fixed shell 91 is fixedly connected and connected with a first liquid guide tube 93, the first liquid guide tube 93 is fixedly connected and connected with a fourth fixed shell 94 which is sleeved on the outside of the first rotating shaft 42 and rotates, and the front part of the fourth fixed shell 94 is slidably provided with a spring which is connected with the rotating wheel 4 The third sliding frame 95 connected to the third fixed shell 91, the first liquid guide tube 93 and the fourth fixed shell 94 are all filled with liquid. The elastic force of the spring between the fourth sliding push rod 92 and the third fixed shell 91 is greater than the friction between the rotating wheel 43 and the round table wheel 41. The first liquid guide tube 93 and the fourth fixed shell 94 are connected with the second liquid guide tube 96. The diameter of the second liquid guide tube 96 is smaller than the diameter of the first liquid guide tube 93. The first liquid guide tube 93, the second liquid guide tube 96 and the fourth fixed shell 94 are connected with a one-way valve. The one-way valve corresponding to the first liquid guide tube 93 is used for liquid to flow from the first liquid guide tube 93 into the fourth fixed shell 94. The one-way valve corresponding to the second liquid guide tube 96 is used for liquid in the fourth fixed shell 94 to flow into the second liquid guide tube. According to the degree of squeezing of the rubber cover 6 by the sow's uterine contraction, the transmission ratio between the round table wheel 41 and the rotating wheel 43 is adjusted to change the beating frequency of the swing plate 55 on the sow, so that the sow can perform a certain frequency of uterine contraction to absorb the injected semen.

[0042] After the rubber sleeve 6 is inserted into the sow's uterus, the above operation is repeated to inject semen into the sow's uterus. During the injection process, the sow's uterine contraction squeezes the spherical end of the rubber sleeve 6 to deform, and the two third sliding plates 71 move accordingly, so that the semen in the second fixed shell 7 is injected into the sow's uterus. The deformation of the spherical end of the rubber sleeve 6 simultaneously allows the liquid to enter the first fixed shell 62 through the connected fixed portion. The liquid squeezes the third sliding push rod 9 to move and compress the connected spring. The third sliding push rod 9 moves and squeezes the fourth sliding push rod 92 at the same time. The fourth sliding push rod 92 moves to allow the liquid in the third fixed shell 91 to enter the fourth fixed shell 94 through the first liquid guide tube 93 and the one-way valve thereon. The liquid enters the fourth fixed shell 94, causing the third sliding frame 95 to drive the rotating wheel 43 to move.

[0043] After the rotating wheel 43 moves, the transmission ratio between the frustum wheel 41 and the rotating wheel 43 becomes smaller. At this time, the third power member 4 works, so that the rotation speed of the rotating wheel 43 and the first rotating shaft 42 slows down, the reciprocating movement frequency of the first sliding frame 54 and the swing plate 55 is reduced, and the stimulation of the swing plate 55 to the sow is reduced. The rotation speed of the first rotating shaft 42 slows down and the rotation speed of the threaded rod 45 is also slowed down, thereby changing the pushing rate of the sliding push plate 17 on the semen in the storage shell 16, reducing the outflow of semen in the storage shell 16, and facilitating the sow's multiple uterine contractions to absorb the semen in the storage shell 16 into the second fixed shell 7, and the semen in the subsequent second fixed shell 7 is injected into the sow's uterus under the action of the sow's uterine contractions.

[0044] After a single uterine contraction of the sow ends, the third sliding push rod 9 moves in the opposite direction to reset under the elastic force of the spring connected to the third sliding push rod 9, and subsequently, the fourth sliding push rod 92 moves in the opposite direction to reset under the elastic force of the spring connected to the fourth sliding push rod 92. At this time, the one-way valve at the connection between the first liquid guiding tube 93 and the fourth fixed shell 94 is in a closed rotation, and the liquid in the fourth fixed shell 94 enters the second liquid guiding tube 96. At this time, the one-way valve at the second liquid guiding tube 96 is in an open state, but because the diameter of the second liquid guiding tube 96 is smaller than the diameter of the first liquid guiding tube 93, the fourth sliding push rod 92 will slowly reset, that is, the rotating wheel 43 slowly resets. When the uterine contraction of the sow weakens for a long time, the rotating wheel 43 and the fourth sliding push rod 92 reset. After the rotating wheel 43 resets, the transmission ratio between the frustum wheel 41 and the rotating wheel 43 becomes larger, the reciprocating frequency of the first sliding frame 54 and the swing plate 55 is accelerated, and the stimulation of the swing plate 55 to the sow is increased, so that the sow resumes uterine contraction and absorbs semen efficiently.

[0045] Embodiment 5: Based on Embodiment 4, Figure 1-Figure 10 As shown, the present invention also provides a method for using an artificial insemination device for sows, based on the above-mentioned artificial insemination device for sows, specifically comprising the following steps: S1: First, inject semen into the storage shell 16, then control the movement of the first sliding plate 14 through the control terminal 111 to drive the animal to be inseminated into the frame 12, and then start the second power member 3 to move the support frame 33 and the pressure plate frame 36 to limit the position of the animal to be inseminated, thereby completing the limit fixation of the animal to be inseminated; S2: After the animal to be inseminated is fixed in position, the rubber cover 6 is inserted into the uterus of the animal to be inseminated, and then the second sliding frame 64 is controlled to move so that the liquid in the first fixed shell 62 passes through the rubber cover 6, and the rubber cover 6 expands and is stuck in the uterus of the animal to be inseminated; S3: After the rubber sleeve 6 is installed, the third power member 4 is controlled to work, and the third power member 4 moves the sliding push plate 17 to push the semen in the storage shell 16 through the connected parts, and the third power member 4 simultaneously makes the first sliding frame 54 and the swing plate 55 move back and forth to beat the animal to be inseminated through the connected parts; S4: The swing plate 55 hits the animal to be inseminated, causing the animal to contract and squeeze the rubber sleeve 6, and the semen in the second fixed shell 7 is injected into the uterus of the animal to be inseminated. At the same time, with the continuous movement of the sliding push plate 17, the semen in the storage shell 16 is injected into the uterus of the animal to be inseminated through the connected pipeline, injection tube 18, second fixed shell 7 and catheter 73, completing the artificial insemination operation; S5: During the artificial insemination operation, the rubber cover 6 is squeezed by the contraction of the animal to be inseminated, causing the second sliding push rod 75 to move accordingly. The second sliding push rod 75 moves through the connected parts to cause the third sliding frame 95 to drive the rotating wheel 43 to move, thereby changing the transmission ratio between the round table wheel 41 and the rotating wheel 43, and adjusting the beating frequency of the swing plate 55 and the moving speed of the sliding push plate 17; S6: After completing the artificial insemination operation, the rubber cover 6 is pulled out, and then the second power member 3 is controlled to work in the reverse direction and reset, so that the support frame 33 and the pressure plate frame 36 release the limit on the animal to be inseminated, and then the switch door 13 is opened to drive the animal to be inseminated out of the frame 12. When the artificial insemination operation is performed again later, the above operation is repeated.
