Detailed implementation manners

[0017] The present utility model will be further described in detail below in conjunction with the drawings and specific implementation manners. The embodiments of the present utility model are given for the purpose of illustration and description, and are not exhaustive or limited to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.

[0018] Such as Figures 1-4A pig artificial insemination device shown in the figure includes an insemination tube 1 and an expansion tube 2 sleeved outside the insemination tube 1. The expansion tube 2 slides and is detachable outside the insemination tube 1. A movable sperm pushing rod 3 is inserted at one end of the insemination tube 1. The other end of the insemination tube 1 is hemispherical and is provided with a plurality of insemination holes 4. A tapered part 5 with gradually decreasing diameters is arranged on the side of the expansion tube 2 close to the insemination holes 4. A spherical cover 6 is sleeved at the connection between the tapered part 5 and the insemination tube 1;

[0019] Based on the above, the setting of the expansion tube 2 facilitates opening the vulva of the sow and inserting part of the insemination tube 1 into the uterus of the sow. The inside of the insemination tube 1 simultaneously functions as a semen storage. By pushing the sperm pushing rod 3, the semen stored inside the insemination tube 1 is pushed from the insemination holes 4 into the uterus of the sow to complete the artificial insemination work of the sow.

[0020] Furthermore, the setting of the tapered part 5 facilitates the insertion of the expansion tube 2 from the vulva of the sow.

[0021] A columnar lubrication chamber 7 is opened inside the expansion tube 2. The extending direction of the lubrication chamber 7 is the same as that of the insemination tube 1. A first piston 8 that slides back and forth is arranged inside the lubrication chamber 7. A first push rod 9 is connected to the first piston 8. The first push rod 9 extends away from the tapered part 5 and penetrates through the expansion tube 2 to extend to the outside. A first push button 10 is installed at the end of the first push rod 9 located outside the expansion tube 2;

[0022] A lubrication pipeline 11 is connected to the end of the lubrication chamber 7 away from the first push button 10. The lubrication pipeline 11 penetrates through the expansion tube 2 and the tapered part 5 and extends to the front end of the tapered part 5. The front end of the lubrication pipeline 11 is located inside the spherical cover 6;

[0023] Based on the above, lubricating fluid is stored inside the lubrication chamber 7. When the expansion tube 2 is inserted into the vulva of the sow, by pressing the first push button 10, the first push rod 9 and the first piston 8 are pushed to move inside the lubrication chamber 7, and the lubricating fluid inside the lubrication chamber 7 is pushed to the spherical cover 6 and overflows to the surface of the tapered part 5. As the tapered part 5 advances inside the vulva of the sow, it will be evenly scattered and smeared on the outside of the tapered part 5 and the expansion tube 2, playing a lubricating role, facilitating the insertion of the expansion tube 2 and the insemination tube 1 into the uterus, reducing the discomfort of the sow, and improving the success rate of artificial insemination.

[0024] A second piston 12 that slides back and forth is arranged inside the insemination tube 1. The end of the sperm pushing rod 3 located inside the insemination tube 1 is fixedly connected to the second piston 12. A second push button 13 is installed at the end of the sperm pushing rod 3 located outside the insemination tube 1;

[0025] Based on the above, the second piston 12 moves within the semen injection tube 1, used to draw the semen for breeding into the interior of the semen injection tube 1, and when the semen injection tube 1 is inserted into the vulva of the sow and reaches deep into the uterus, it pushes the semen injection rod 3 through the second piston 12 to inject the semen into the uterus of the sow, completing the breeding operation.

[0026] An alignment ring 14 is also sleeved outside the semen injection tube 1, and the alignment ring 14 fits against the end of the expansion tube 2;

[0027] A prismatic grip portion 15 is also sleeved on the end of the semen injection tube 1 away from the semen injection hole 4;

[0028] Furthermore, the expansion tube 2 is sleeved outside the semen injection tube 1. Threads are provided on both the inner wall of the expansion tube 2 and the outer wall of the semen injection tube 1. When installing, the user holds the grip portion 15 with one hand and holds the expansion tube 2 with the other hand, sleeved the expansion tube 2 outside the semen injection tube 1 and rotates it. The expansion tube 2 moves and is fixed outside the semen injection tube 1 through the threads, and the alignment ring 14 is used to limit the moving distance of the expansion tube 2.

[0029] An anti-recoil chamber 16 is opened inside the spherical cover 6. The anti-recoil chamber 16 faces the conical portion 5, and there is a gap between the edge of the anti-recoil chamber 16 and the outer wall of the conical portion 5.

[0030] Furthermore, the spherical cover 6 is detachable from the semen injection tube 1. The spherical cover 6 is sleeved outside the semen injection tube 1. Threads are provided on the outer wall of the semen injection tube 1 corresponding to the spherical cover 6, and the two are disassembled and installed through the threads. The end of the lubricating pipe 11 extends into the interior of the spherical cover 6. After pushing the first piston 8 to deliver the lubricating fluid into the anti-recoil chamber 16 inside the spherical cover 6, the lubricating fluid will overflow outward along the gap between the spherical cover 6 and the conical portion 5, and then evenly coat the outer wall of the conical portion 5. When the user continuously inserts the semen injection tube 1 and the expansion tube 2 into the vulva of the sow, the lubricating fluid will be evenly smeared automatically, facilitating the breeding operation.

[0031] Based on the above, during use, first reciprocate the first push rod 9 and the first piston 8 to suck the lubricating fluid from the lubricating pipeline 11 into the interior of the lubricating chamber 7. Then, put the expansion cylinder 2 on the outside of the insemination cylinder 1, put the spherical cover 6 on the connection between the expansion cylinder 2 and the conical part 5. Next, suck the semen for breeding into the interior of the insemination cylinder 1, and then insert it into the vulva of the sow. During this process, slowly push the first knob. Through the first push rod 9 and the first piston 8, the lubricating fluid is pushed out from the lubricating pipeline 11, overflows onto the conical part 5 through the backflush chamber 16 and the spherical cover 6, and then, along with the movement of the expansion cylinder 2 and the insemination cylinder 1, is evenly applied to the outside of the conical part 5 and the expansion cylinder 2 to play a lubricating role, facilitating the insertion of the expansion cylinder 2 and the insemination cylinder 1 into the uterus, improving the insemination success rate. When the insemination cylinder 1 reaches deep into the uterus of the sow, push the semen pushing rod 3 to push the semen inside the insemination cylinder 1 into the uterus of the sow.
