DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] Embodiment 1, as Figure 1 , Figure 2 and Figure 3 As shown, an artificial semen collector for collecting semen from sheep and a semen collection method thereof, comprising an operating table 1, two symmetrically distributed enclosures 2 are fixedly connected to the middle of the front side of the upper end of the operating table 1, a partition 3 is rotatably connected to the front end of the enclosure 2 on the right side, three railings 4 are fixedly connected to the left and right sides of the middle of the upper end of the operating table 1 in a linear array, and a retaining shed 5 is fixedly connected to the upper ends of the six railings 4, and a semen collection device 6 is fixedly installed in the middle of the rear side of the upper end of the operating table 1. The semen collection device 6 is provided to facilitate semen collection work, and can be switched between the state of semen collection and semen storage. When collecting semen, one end of the semen collection device 6 can be aligned with the vagina of the ewe, and the other end corresponds to the position of the penis of the ram, so as to simulate the position of the ram and the ewe during mating, thereby improving the subsequent semen collection efficiency;

[0038] The rear ends of the two rear railings 4 are fixedly installed with leg-releasing assemblies 7. The leg-releasing assemblies 7 cooperate with the sperm collection device 6 so that when the ram is performing simulated mating, the ram's front legs can be manually placed on the surface of the leg-releasing assemblies 7, thereby realizing the mating action of the ram during simulated mating, and the leg-releasing assemblies 7 can drive the sperm collection device 6 to move upward, thereby realizing that the sperm collection device 6 replaces the ewe's vagina to complete the sperm collection work.

[0039] Embodiment 2: This embodiment is based on Embodiment 1 and is for achieving the purpose of simulating mating between a ram and a ewe.

[0040] For details, see Figure 4 , Figure 5 , Figure 6 and Fig. 9 , the two leg-releasing assemblies 7 each include two guide posts 71, both of which are provided with L-shaped grooves 72 in the middle of the rear ends of the two railings 4 on the rear side, the two guide posts 71 are respectively located in the inner cavities of the two L-shaped grooves 72, the upper and lower ends of the two guide posts 71 are fixedly connected to the top and bottom walls of the L-shaped grooves 72, the outer surfaces of the two guide posts 71 are slidably connected with hollow sliders 73, the two hollow sliders 73 are slidably connected to the inner surfaces of the L-shaped grooves 72, the two hollow sliders 73 are fixedly connected with a leg-releasing plate 74 at one end close to each other, the bottom walls of the two L-shaped grooves 72 and the lower ends of the hollow sliders 73 are fixedly connected with springs three 75, the two springs three 75 are respectively located on the outside of the guide posts 71, the sides of the rear ends of the two hollow sliders 73 away from each other are rotatably connected with a rotating rod 76, and the rear ends of the two rotating rods 76 are fixedly installed with a driving assembly 77.

[0041] Furthermore, the driving components 77 include gears 771 fixedly connected to the rear ends of the two rotating rods 76, racks 1 772 are slidably connected to the sides of the rear ends of the two railings 4 located at the rear side that are close to each other, and racks 2 773 are fixedly connected to the sides of the rear ends of the two railings 4 located at the rear side that are away from each other, and the gears 771 are respectively meshed with racks 1 772 and racks 2 773.

[0042] Furthermore, the two leg resting plates 74 are arranged in the form of semicircular arc blocks, and rubber pads are fixedly connected to the outer surfaces of the two leg resting plates 74 .

[0043] First, the partition 3 is opened to one side so that the front sides of the two enclosures 2 are in an open state, and then the ewe in estrus is driven in. After the ewe is in the fence formed by the six rails 4, the partition 3 is closed;

[0044] At this time, the ram is pulled to the rear side of the ewe's buttocks, so that the ram smells the ewe's buttocks. After a physiological reaction occurs, it is only necessary to manually place the ram's two front legs on the upper ends of the two leg-laying boards 74. As can be seen from the above, the two leg-laying boards 74 are arranged in a semicircular arc block, and the outer surfaces of the two leg-laying boards 74 are fixedly connected with rubber pads, so that the two leg-laying boards 74 fit the sheep's legs better, and under the action of the rubber pads, the ram's front legs can be prevented from being scratched during simulated mating;

[0045] After the ram's front legs are placed on the upper ends of the two leg-laying plates 74, the two leg-laying plates 74 are pressed downward, and then the two leg-laying plates 74 drive the hollow sliders 73 fixedly connected thereto to slide downward from the L-shaped grooves 72 under the guidance of the guide pillars 71. When the two hollow sliders 73 move downward, they can simultaneously drive the rotating rods 76 connected to the front ends thereof to slide downward in the L-shaped grooves 72, and the hollow sliders 73 squeeze and contract the springs 75.

[0046] When the rotating rod 76 moves downward, it can simultaneously drive the gear 771 fixedly connected to its rear end to move downward. As can be seen from the above, the gear 771 is respectively meshed with the rack 1 772 and the rack 2 773, and the rack 2 773 is fixedly connected to the corresponding rear end of the handrail 4, thereby causing the gear 771 to rotate, and then driving the rack 1 772 to move upward until the hollow slider 73 falls to the point where the spring 3 75 cannot be squeezed and contracted.

[0047] At this time, the ram's front legs are placed on the upper ends of the two leg-laying plates 74 and are in an upwardly lifted state, thereby achieving a simulated mating action.

[0048] Embodiment 3: This embodiment is based on embodiment 2 and aims to simulate the vaginal temperature of the ewe before sperm collection.

[0049] For details, see Figure 7 and Figure 8 The simulated vagina component 696 includes a cylinder 6961 fixedly connected to the inner surface of a connecting ring 695, a water injection pipe 6962 is fixedly connected to the upper outer surface of the cylinder 6961, a threaded cover 6963 is threadedly connected to the inner surface of the water injection pipe 6962, a water-isolating membrane 6964 is provided on the inner surface of the cylinder 6961, and water-isolating rings 6965 are fixedly connected to the front and rear ends of the cylinder 6961, and the ends of the two water-isolating rings 6965 close to each other are fixedly connected to the water-isolating membrane 6964.

[0050] Before starting the semen collection work, it is necessary to rotate and open the threaded cover 6963, and then pour warm water from the water injection pipe 6962 into the cavity formed by the outer surface of the water-isolating membrane 6964 and the inner surface of the cylinder 6961. Since the two water-isolating rings 6965 are respectively fixedly connected to the front and rear ends of the water-isolating membrane 6964, the cavity formed by the outer surface of the water-isolating membrane 6964 and the inner surface of the cylinder 6961 is a closed inner cavity. Wait until the warm water is poured until the inner surface of the water-isolating membrane 6964 is slightly bulged, and then insert the semen collection tube needed for semen collection into the water-isolating ring 6965 on the front side. At this time, the bulging water-isolating membrane 6964 will wrap the semen collection tube, which is convenient for the subsequent semen collection work. Finally, the threaded cover 6963 can be rotated to close.

[0051] The sperm collection tube mentioned above is a conventional design in the prior art, which only needs to receive the semen produced by the ram. The specific shape and volume can be adjusted according to actual production needs, so this solution will not be elaborated in detail;

[0052] In addition, the warm water is poured into the water injection pipe 6962 to simulate the temperature in the ewe's vagina, so that the ram is more comfortable during simulated mating, thereby improving the efficiency of semen collection. This operation is a routine operation in the prior art, so this solution will not be elaborated in detail.

[0053] Embodiment 4: This embodiment is based on embodiment 2 and is for achieving the purpose of the leg-releasing assembly 7 driving the semen collecting device 6 to perform semen collecting work.

[0054] For details, see Figure 6 , Figure 7 , Figure 8 and Fig.10 The sperm collection device 6 includes a hollow rod 61 fixedly connected to the middle part of the rear side of the upper end of the operating table 1, a sliding rod 62 is slidably connected to the inner surface of the hollow rod 61, and two symmetrically distributed springs 63 are fixedly connected to the lower end of the sliding rod 62. The lower ends of the two springs 63 are fixedly connected to the upper end of the operating table 1. Guide grooves 64 are provided at the lower left and right ends of the sliding rod 62, and a placement block 65 is fixedly connected to the upper end of the sliding rod 62. The bottom walls and top walls of the two guide grooves 64 are both fixedly connected to guide rods 66, and the outer surfaces of the two guide rods 66 are both slidably connected to L-shaped rods 67. The two L-shaped rods 67 are respectively slidably connected to the inner cavity of the guide groove 64, and the top wall of the guide groove 64 and the upper end of the L-shaped rod 67 are fixedly connected to springs 68. The two springs 68 are respectively located on the outside of the guide rod 66, and the front ends of the two L-shaped rods 67 are fixedly installed with lifting components 69.

[0055] Furthermore, the two lifting components 69 each include a connecting rod 1 691 fixedly connected to the front ends of the two L-shaped rods 67, a connecting rod 2 692 fixedly connected to the upper ends of the two connecting rods 1 691 close to each other, a circular hole block 693 fixedly connected to the lower edges of the rear ends of the two connecting rods 2 692, a connecting rod 694 rotatably connected to the inner surfaces of the two circular hole blocks 693, a connecting ring 695 rotatably connected to the ends of the two connecting rods 694 close to each other, and a simulated vagina component 696 fixedly installed on the inner surface of the connecting ring 695.

[0056] Furthermore, the placement block 65 is a rubber cushion.

[0057] Furthermore, the lower ends of the two racks 772 are fixedly connected to the upper ends of the connecting rods 692 respectively.

[0058] As can be seen from the above, the lower ends of the two racks 772 are fixedly connected to the upper ends of the connecting rods 692, respectively. Therefore, when the two racks 772 move upward at the same time, they can simultaneously drive the connecting rods 692 fixedly connected thereto to move upward, and the connecting rods 692 can drive the connecting rods 691 fixedly connected thereto to move upward. The initial state of the spring 63 is that it is squeezed and contracted by the device at its upper end. Therefore, when the connecting rods 692 move upward, the circular hole blocks 693 on both sides are driven to move upward. At the same time, the L-shaped rods 67 on both sides drive the slides 691 to move upward. The rods 62 move upwards simultaneously until the lower edge of the slide rod 62 is blocked by the edge of the inner surface of the hollow rod 61 and cannot move upwards any further. At this time, the slide rod 62 drives the placement block 65 to support the rear end of the cylinder 6961 to move upwards. The connecting rods 694 on both sides move upwards following the circular hole blocks 693 on both sides, driving the connecting ring 695 connected with the rotating ring to move upwards. The connecting ring 695 can drive the front end of the cylinder 6961 fixedly connected thereto to move upwards, thereby realizing that the front end and the rear end of the cylinder 6961 move upwards at the same time.

[0059] When the sliding rod 62 can no longer move upward, there is still some distance between the rear end of the cylinder 6961 and the vagina of the ewe, and the L-shaped rods 67 on both sides can continue to move upward in the guide groove 64, squeezing and contracting the spring 2 68, and the guide rod 1 66 plays a role of limiting guidance. When the L-shaped rod 67 continues to move upward with the connecting rod 2 692, the circular hole block 693 also drives the connecting rod 694 to move upward, and then the connecting rods 694 on both sides drive the connecting ring 695 rotatably connected thereto to move upward again, so that the front end height of the cylinder 6961 is greater than the rear end height of the cylinder 6961. At this time, the rear end of the cylinder 6961 rests on the upper end of the placement block 65, and its front end corresponds to the vaginal position of the ewe. Then the ram puts his penis from the water-proof ring 6965 on the rear side into the water-proof membrane 6964 to simulate the mating process, and then the produced semen will fall into the sperm collection tube prepared in advance;

[0060] As can be seen from the above, the placement block 65 is a rubber cushion. By setting the placement block 65 as a rubber cushion, the cylinder 6961 can be prevented from sliding off its surface, and the ram's penis can be prevented from colliding with its surface and causing damage during alignment;

[0061] During this process, human observation is required to prevent the ram's penis from being misaligned. If this happens, manual assistance can be provided.

[0062] After the simulated mating process is over, the personnel are prompted to remove the front end of the ram from the upper ends of the two leg plates 74, and then under the action of spring 1 63 and spring 2 68, the device is restored to its initial state. In the initial state, the rear end height of the cylinder 6961 is greater than its front end height, so that the semen in the sperm collection tube cannot leak out of the sperm collection tube, thereby improving the sperm collection efficiency.

[0063] Embodiment 5: This embodiment also provides a method for using an artificial semen collector for sheep semen collection:

[0064] S1, by opening the partition 3, then driving a ewe in estrus into the fence formed by six rails 4, and then closing the partition 3 so that the ewe is enclosed therein;

[0065] S2, then the ram is led to the rear side of the buttocks of the ewe in estrus, so that the ram first smells the buttocks of the ewe, and the front legs of the ram are manually placed on the surface of the leg placement component 7 to simulate the action of the ram and the ewe when mating;

[0066] S3, when the ram's front legs are placed on the surface of the leg-laying assembly 7, the semen collection device 6 will be lifted upwards, and then the tilted state will be changed so that one end is facing the ewe's vagina and the other end is aligned with the ram's penis;

[0067] S4. Before simulating mating, warm water needs to be filled into the simulated vagina component 696 to simulate the temperature in the ewe's vagina during mating, so as to improve the success rate of subsequent semen collection. At the same time, a semen collection tube for semen collection is inserted into the simulated vagina component 696 to collect semen produced by the ram during mating;

[0068] S5. Finally, after the simulated mating and semen collection, the ram's front legs are lifted and removed, prompting the semen collection device 6 and the simulated vagina component 696 to return to their initial state. At this time, the tilt state of the simulated vagina component 696 is changed again, so that the semen in the semen collection tube always flows downward and accumulates, avoiding the outflow of the collected semen and causing unnecessary waste.

[0069] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.

The artificial semen collector for collecting semen from sheep and the method for collecting semen according to claim 1, characterized in that: The two leg-resting plates (74) are arranged in the form of semicircular arc blocks, and rubber cushions are fixedly connected to the outer surfaces of the two leg-resting plates (74).

5. A method for using the artificial semen collection device for sheep semen collection according to any one of claims 1 to 4, characterized in that: The method includes: S1, by opening the partition (3), then driving a ewe in estrus into the fence formed by six rails (4), and then closing the partition (3) so that the ewe is enclosed therein; S2, then the ram is led to the rear side of the buttocks of the ewe in estrus, so that the ram first smells the ewe's buttocks, and the ram's front legs are manually placed on the surface of the leg placement component (7) to simulate the action of the ram and the ewe when mating; S3, when the ram's front legs are placed on the surface of the leg placement assembly (7), the semen collection device (6) is lifted upwards and then switched to an inclined state so that one end faces the ewe's vagina and the other end is aligned with the ram's penis; S4. Before simulating mating, the simulated vagina component (696) is filled with warm water to simulate the temperature in the vagina of the ewe during mating, so as to improve the success rate of subsequent semen collection. At the same time, a semen collection tube for semen collection is inserted into the simulated vagina component (696) to collect semen produced by the ram during mating; S5. Finally, after the simulated mating and semen collection, the ram's front legs are lifted and removed, prompting the semen collection device (6) and the simulated vagina component (696) to return to their initial state. At this time, the tilt state of the simulated vagina component (696) is changed again, so that the semen in the semen collection tube always flows downward and accumulates, thereby preventing the collected semen from flowing out and causing unnecessary waste.
