Description

TECHNICAL FIELD

[0002] In modern animal husbandry, artificial insemination technology, as a key means to improve reproductive efficiency, is widely used in the reproductive management of livestock. The core of this technology is to accurately deliver the selected and treated semen into the uterus of the sow in estrus through meticulous operation to promote the fertilization process, thereby improving genetic quality and production efficiency. However, the traditional artificial insemination method, especially when using a manual injection device for insemination, has certain challenges and limitations.

[0003] During the implementation of insemination, the insertion action of the injection device often causes irritation to the sensitive sow, triggering a series of physiological and behavioral reactions. The most typical one is the animal's violent struggle. This struggle not only disrupts the smooth progress of the insemination operation, increasing the difficulty of the operator, but also when the animal moves significantly due to discomfort, the handheld injection device is easily pulled out of the uterus, resulting in the leakage of precious semen.

The front and rear portions of the second fixed shell 7 are slidingly provided with third sliding plates 71, and the two third sliding plates 71 are provided with tension springs between the second fixed shell 7. The third sliding plates 71 are in contact with the liquid in the chamber of the rubber sleeve 6. The right portion of the injection pipe 18 is slidingly provided with a first ball 72 for blocking the through hole thereof, and the first ball 72 is provided with a tension spring between the injection pipe 18. The second fixed shell 7 and the rubber sleeve 6 are fixedly connected with a conduit 73 for communicating the outside of the second fixed shell 7 and the rubber sleeve 6. The right portion of the conduit 73 is slidingly provided with a second ball 74 for blocking the through hole thereof, and the second ball 74 is provided with a tension spring between the conduit 73. The sliding push plate 17 is slidingly provided with a second sliding push rod 75, the lower portion of the second sliding push rod 75 is slidingly matched with the storage shell 16, and the second sliding push rod 75 is provided with a spring between the sliding push plate 17. The spring between the second sliding push rod 75 and the sliding push plate 17 has a smaller elastic coefficient than the tension spring between the first ball 72 and the injection pipe 18. The third sliding plate 71 and the second fixed shell 7 have a larger elastic coefficient of the tension spring than the tension spring between the first ball 72 and the injection pipe 18. The deformation of the spherical end of the rubber sleeve 6 makes the first ball 72 and the second ball 74 reciprocate, and the semen in the second fixed shell 7 is injected into the uterus of the sow under the condition of uterine contraction, so as to facilitate the efficient absorption of the semen by the sow.

[0050] After the sow is limited by the supporting plate frame 33 and the pressing plate frame 36 in the frame 12, the operator repeats the above operation to adjust the height of the second sliding plate 51. At this time, the spring connected with the second sliding frame 64 is in a compressed state in the initial state. After the height of the second sliding plate 51 is adjusted, the operator holds the second sliding frame 64 to keep the second sliding frame 64 in the initial state, that is, the first sliding push rod 63 is still located at the lower end of the inclined groove of the second sliding frame 64. Then the operator inserts the rubber sleeve 6 into the uterus of the sow, and then releases the second sliding frame 64. Under the action of the elastic force of the spring connected with the second sliding frame 64, the inclined groove of the second sliding frame 64 extrudes 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 to be injected into the cavity of the rubber sleeve 6 through the pipeline, so that the right end of the rubber sleeve 6 expands to form a ball clamped in the uterus of the sow.

[0051] After the rubber sleeve 6 is inserted into the sow's uterus, the operator starts the third power component 4 through the control terminal 111, and the third power component 4 works to repeat the above operation to slowly move the sliding push plate 17 downward, and the sliding push plate 17 moves downward to drive the second sliding push rod 75 to move downward through the connected spring, at this time, the first ball 72 blocks the injection pipe 18, and the sliding push plate 17 is compressed and deformed in the process of moving downward, and the spring connected with the sliding push plate 17 is compressed and deformed to pressurize the semen in the storage shell 16.

[0052] The third power component 4 works to repeat the above operation to reciprocally move the first sliding frame 54 and the swing plate 55 to stimulate the sow, so that the sow has uterine contraction, the sow uterine contraction extrudes the spherical part of the rubber sleeve 6, under the extrusion, the liquid of the spherical part of the rubber sleeve 6 extrudes the two third sliding plates 71 to move and stretch the connected tension spring, and at this time, the two third sliding plates 71 move to extrude the semen in the second fixed shell 7 into the catheter 73, the subsequent semen is injected into the sow's uterus through the second ball 74, so that the semen is injected in the state of the sow's uterine contraction, and the absorption efficiency of the sow's uterus to the semen is further improved, and then the sow's uterus is reset under the tension of the spring on the third sliding plate 71, at this time, the second ball 74 is first retracted into the catheter 73 to block the catheter 73, and the subsequent absorption in the resetting process of the third sliding plate 71, the semen in the injection pipe 18 is injected into the second fixed shell 7 through the first ball 72, and the subsequent uterine contraction of the sow makes the semen be slowly and intermittently injected into the sow's uterus.

[0053] When the sow's uterine contraction is poor, the spherical part of the rubber sleeve 6 will not change obviously, that is, the third sliding plate 71 will not move violently, at this time, the sliding push plate 17 slowly moves downward to gradually increase the required elastic force of the spring connected thereto, 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 ball 72, the semen is injected into the second fixed shell 7 through the injection pipe 18, and when the elastic force of the spring connected to the sliding push plate 17 is greater than the tension of the tension spring on the second ball 74, the semen is injected into the sow's uterus through the catheter 73, and the artificial insemination operation is completed.

[0054] After the artificial insemination operation is completed, the operator repeats the above operation to turn off the third power component 4, then pulls the second sliding frame 64 to reset, and pulls out the rubber sleeve 6 from the sow's body, and makes the fixed rod 61 support and limit the second sliding frame 64 again, then controls the second power component 3 to reset, and opens the switch door 13 to drive the inseminated sow out of the frame 12.

[0055] It is found through research that in the process of stimulating the sow's uterine contraction to absorb the artificially injected semen, when the sow is stimulated too much, the struggle of the sow is intensified, which affects the stability of the semen injection.

[0056] Example 4: Based on example 3, as shown in Figure 2 , Figure 9 and Figure 10 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, and the rotating wheel 43 is located in the spline groove part of the first rotating shaft 42 and slides. The adjusting mechanism comprises a third sliding push rod 9 which is slidingly arranged on the front part of the first fixed shell 62. A spring is arranged 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 with a third fixed shell 91. A fourth sliding push rod 92 is slidingly arranged on the rear part of the third fixed shell 91. The fourth sliding push rod 92 is in extrusion fit with the third sliding push rod 9. A spring is arranged 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 with and communicated with a first liquid guide pipe 93. The first liquid guide pipe 93 is fixedly connected with and communicated with a fourth fixed shell 94 which rotates outside the first rotating shaft 42. The front part of the fourth fixed shell 94 is slidingly arranged with a third sliding frame 95 which is rotationally connected with the rotating wheel 43. The third fixed shell 91, the first liquid guide pipe 93 and the fourth fixed shell 94 are all filled with liquid. The spring force between the fourth sliding push rod 92 and the third fixed shell 91 is greater than the friction force between the rotating wheel 43 and the circular table wheel 41. The first liquid guide pipe 93 and the fourth fixed shell 94 are communicated with a second liquid guide pipe 96. The diameter of the second liquid guide pipe 96 is smaller than that of the first liquid guide pipe 93. One-way valves are arranged in the communication openings of the first liquid guide pipe 93 and the second liquid guide pipe 96. The one-way valve corresponding to the first liquid guide pipe 93 is used for the liquid to flow from the inside of the first liquid guide pipe 93 into the fourth fixed shell 94. The one-way valve corresponding to the second liquid guide pipe 96 is used for the liquid in the fourth fixed shell 94 to flow into the second liquid guide pipe 96. According to the degree of extrusion of the rubber sleeve 6 by the sow uterine contraction, the transmission ratio between the circular table wheel 41 and the rotating wheel 43 is adjusted, the frequency of the beating plate 55 against the sow is changed, and the sow is made to perform uterine contraction at a certain frequency to absorb the injected semen.

[0057] After the rubber sleeve 6 is inserted into the sow uterus, the above operation is repeated to inject the semen into the sow uterus. During the injection process, the sow uterine contraction extrudes the spherical end of the rubber sleeve 6 to deform, the two third sliding plates 71 move correspondingly, the semen in the second fixed shell 7 is injected into the sow uterus, the deformation of the spherical end of the rubber sleeve 6 simultaneously causes the liquid to enter the first fixed shell 62 through the connected fixed part, the liquid extrudes the third sliding push rod 9 to move and compress the connected spring, the third sliding push rod 9 moves and extrudes the fourth sliding push rod 92, the fourth sliding push rod 92 moves to make the liquid in the third fixed shell 91 enter the fourth fixed shell 94 through the first liquid guide pipe 93 and the one-way valve thereon, and the liquid entering the fourth fixed shell 94 makes the third sliding frame 95 drive the rotating wheel 43 to move.

[0058] After the rotation wheel 43 moves, the transmission ratio between the circular table wheel 41 and the rotation wheel 43 becomes smaller, at this time, the third power component 4 works, the rotation speed of the rotation wheel 43 and the first rotating shaft 42 becomes slow, the reciprocating movement frequency of the first sliding frame 54 and the swing plate 55 is reduced, the stimulation of the swing plate 55 to the sow is reduced, the rotation speed of the first rotating shaft 42 becomes slow, and the rotation speed of the threaded rod 45 becomes slow, so that the pushing rate of the sliding push plate 17 to the semen in the storage shell 16 is changed, the outflow of the semen in the storage shell 16 is slowed down, the sow can suck the semen in the storage shell 16 into the second fixed shell 7 for multiple times, and the subsequent semen in the second fixed shell 7 is injected into the uterus of the sow under the action of the sow.

[0059] After the single uterine contraction of the sow is completed, the third sliding push rod 9 moves reversely and resets under the elastic force of the spring connected to the third sliding push rod 9, and the fourth sliding push rod 92 moves reversely and resets under the elastic force of the spring connected to the fourth sliding push rod 92, at this time, the one-way valve at the communication position of the first liquid guide pipe 93 and the fourth fixed shell 94 is in a closed rotation state, the liquid in the fourth fixed shell 94 enters the second liquid guide pipe 96, at this time, the one-way valve at the second liquid guide pipe 96 is in an open state, but since the diameter of the second liquid guide pipe 96 is smaller than that of the first liquid guide pipe 93, the fourth sliding push rod 92 will slowly reset, that is, the rotation wheel 43 slowly resets, when the uterine contraction degree of the sow is weak for a long time, the rotation wheel 43 and the fourth sliding push rod 92 reset, after the rotation wheel 43 resets, the transmission ratio between the circular table wheel 41 and the rotation wheel 43 becomes larger, the reciprocating movement frequency of the first sliding frame 54 and the swing plate 55 is increased, the stimulation of the swing plate 55 to the sow is increased, and the sow recovers uterine contraction to efficiently absorb the semen.
