Description

Technical Field

[0001] This utility model relates to the field of animal reproduction technology, and in particular to a simulation training device for estrus detection and artificial insemination in pigs. Background Technology

[0002] There are generally two methods of breeding sows: direct mating and artificial insemination. Direct mating requires a large number of boars, resulting in high feeding costs, low utilization of excellent boars, and a higher risk of disease transmission, leading to their gradual culling in farms. Artificial insemination, on the other hand, is beneficial for the breeding and promotion of new pig breeds. It reduces the labor intensity of mating sows, saves time, and avoids diseases caused by natural mating between boars and sows. Therefore, artificial insemination of sows is widely used in piglet production.

[0003] Artificial insemination of sows is an important technology that has been developed in recent years. It involves the technical aspects of modern large-scale pig farming and directly determines and improves the economic benefits and development of pig farming enterprises. It can not only improve the utilization rate of superior boars, overcome the breeding difficulties caused by small individual boars, and reduce the spread of diseases, but also significantly improve the reproductive efficiency of pigs, achieve resource sharing, and play an important role in the purification of diseases in pig farms.

[0004] Since artificial insemination of sows is a passive process, when using existing insemination tubes to artificially inseminate pigs, sperm backflow can reduce the sow's chances of conception, making it impossible to achieve the desired conception rate.

[0005] To increase the success rate of artificial insemination in sows, a relatively skilled technique is required. However, because it is impossible to directly observe the internal organs of the pig, trainees face significant cognitive difficulties and struggle to master the techniques. Furthermore, instructors cannot provide simulated training or objectively evaluate trainees' performance. In addition, repeated experiments on live pigs can cause considerable harm to the pigs and pose certain risks to the trainees. Therefore, there is an urgent need for equipment that allows trainees to practice. Utility Model Content

[0006] Therefore, the technical problem to be solved by this utility model is to overcome the problem that the success rate of artificial insemination in the prior art is low because the operators are not skilled enough to practice directly on live pigs.

[0007] To solve the above-mentioned technical problems, this utility model provides a simulation training device for estrus detection and artificial insemination in pigs, comprising: a simulated shell designed in the shape of an animal; reproductive organs disposed on the simulated shell; and an insemination gun for insertion into the reproductive organs, capable of inseminating sperm into the reproductive organs. The reproductive organs include a vulva, a supporting component, a simulated vagina, a simulated cervical os base, a shielding component, and a distance calculation component. The vulva is disposed on the tail portion outside the simulated shell. The supporting component and the simulated vagina are both disposed inside the simulated shell, with the simulated vagina mounted on the supporting component. The two ends of the simulated vagina are respectively connected to the vulva and the simulated cervical os base. The shielding component and the distance calculation component are both disposed on the simulated cervical os base. When the shielding component is open, it allows the insemination gun to pass through. The distance calculation component is used to calculate the insertion depth of the insemination gun. This utility model relates to a simulation training device for estrus detection and artificial insemination in pigs. By inserting an insemination gun into different positions of simulated reproductive organs, trainees can understand the correctness of the insertion method. Sensors are set at different parts of the reproductive organs, and the positioning of the sensors can indicate the position of the insemination gun, allowing trainees to correct their mistakes in a timely manner. Through repeated training, trainees can shorten the time to master insemination techniques and improve their proficiency in insemination.

[0008] In one embodiment of this utility model, a micro switch is provided on the cervical os simulation base, and the micro switch is used to sense when the head of the insemination gun reaches the position of the distance calculation component.

[0009] In one embodiment of this utility model, the cervical os simulation base is provided with two symmetrically arranged through-beam sensors. The output end of the through-beam sensors is emitted to the internal os of the cervix of the simulated vagina, and the output end of the through-beam sensors is used to sense when the insemination gun reaches the internal os of the cervix.

[0010] In one embodiment of this utility model, both the vulva and the simulated vagina are made of silicone.

[0011] In one embodiment of this utility model, both the support component and the simulated vagina are hollow cylindrical, and the outer wall of the simulated vagina is fitted to the inner wall of the support component. The side wall of the support component is provided with several through holes. A position sensor is installed on the outer wall of the simulated vagina. The position sensor is located in the through hole and is used to sense the position of the insemination gun head.

[0012] In one embodiment of this utility model, the inner wall of the simulated vagina near the cervical os simulated base is provided with a plurality of protrusions, the protrusions being hemispherical and protruding from the inner wall of the simulated vagina.

[0013] In one embodiment of this utility model, the shielding component includes a servo motor and a shielding plate. The servo motor is mounted on the cervical os simulation base. The shielding plate is connected to the output end of the servo motor, and the shielding plate and the output end of the servo motor are eccentrically arranged. The servo motor is used to drive the shielding plate to rotate to shield or open the cervical os of the simulated vagina.

[0014] In one embodiment of this utility model, the distance calculation component includes a motor, a first gear, a second gear, and an encoder. The encoder is connected to the second gear, the second gear meshes with the first gear, the first gear is connected to the output shaft of the motor, the insemination gun is in contact with the encoder, and the encoder is used to calculate the insertion depth of the insemination gun.

[0015] In one embodiment of this utility model, a touch sensor is provided in the vulva, and the touch sensor is used to sense the wiping signal of the vulva.

[0016] In one embodiment of this utility model, a force sensor is provided at the foot position of the simulated shell, and the force sensor is used to sense the pressing signal on the simulated shell.

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0032] Reference Figure 1 As shown, the simulating training device for estrus detection and artificial insemination in pigs of this utility model includes three main parts: a simulation shell 1, reproductive organs 2, and an insemination gun 3. The simulation shell 1 is designed to resemble an animal. The reproductive organs 2 are mounted on the simulation shell 1. The insemination gun 3 is inserted into the reproductive organs 2 and is capable of inseminating the reproductive organs 2. The simulation shell 1 is made of fiberglass to create an animal model, thereby achieving a more realistic simulation effect.

[0033] Reference Figure 2-7 As shown, the reproductive organ 2 includes a vulva 21, a support component 22, a simulated vagina 23, a simulated cervical base 24, a shielding component 25, and a distance calculation component 26. The vulva 21 is located on the tail end outside the simulated housing 1. The support component 22 and the simulated vagina 23 are both located inside the simulated housing 1, and the simulated vagina 23 is mounted on the support component 22. The two ends of the simulated vagina 23 are respectively connected to the vulva 21 and the simulated cervical base 24. The shielding component 25 and the distance calculation component 26 are both located on the simulated cervical base 24. When the shielding component 25 is open, it allows the insemination gun 3 to pass through. The distance calculation component 26 is used to calculate the insertion depth of the insemination gun 3. A microswitch 27 is provided on the simulated cervical base 24. The microswitch 27 is used to sense when the head of the insemination gun 3 reaches the position of the distance calculation component 26.

[0034] Before performing simulated insemination, the vulva 21 needs to be wiped to simulate the actual procedure. Therefore, a touch sensor is installed inside the vulva 21 to detect the wiping signal. When the operator wipes the vulva 21, the touch sensor detects the wiping and simulates the operation on the pig.

[0035] Force sensors are installed at the foot positions of the aforementioned simulation shell 1. These force sensors are used to sense pressure signals applied to the simulation shell 1. For a specific simulated pig, there are four force sensors at the foot positions of the simulated pig's shell 1. When the operator presses on the pig's back, the force sensors will react, simulating the operation on the pig.

[0036] In addition, the cervical os simulation base 24 is provided with two symmetrically arranged through-beam sensors 28. The output end of the through-beam sensors 28 is emitted to the internal os of the cervix of the simulated vagina 23, and the output end of the through-beam sensors 28 is used to sense the arrival of the insemination gun 3 at the internal os of the cervix.

[0037] In the above structure, both the vulva 21 and the simulated vagina 23 are made of silicone. The soft silicone used for the vulva 21 and simulated vagina 23 simulates the feel of animal organs. The support component 22 is made of a harder material, providing support for the simulated vagina 23. By using silicone for the vulva 21 and simulated vagina 23, the model becomes more realistic, more similar to actual conditions during operation, and makes the training more practically valuable for students when applied to real-world situations.

[0038] In the above structure, the vulva 21 is provided with a connecting flange 211, which is fixedly installed on the tail of the simulation shell 1. The simulated vagina 23 is provided with a connecting flange 231 at one end near the vulva 21, and the connecting flange 231 is connected to the connecting flange 211.

[0039] In the above structure, both the support component 22 and the simulated vagina 23 are hollow cylindrical, and the outer wall of the simulated vagina 23 is fitted to the inner wall of the support component 22. The side wall of the support component 22 has several through holes 221. A position sensor 233 is installed on the outer wall of the simulated vagina 23, located within the through holes 221. The position sensor 233 is used to sense the position of the insemination gun 3 head. By setting multiple sensors 233, the position of the insemination gun 3 is detected and positioned, and the information is transmitted to the host computer and displayed on a monitor, allowing the trainee to more accurately grasp the correct position. A support frame 11 is installed inside the simulated housing 1, and the support component 22 is mounted on the support frame 11. Connecting flanges 222 and 223 are respectively provided at both ends of the support component 22 along its axial direction. The simulated vagina 23 has several protrusions 234 on the inner wall of the end near the cervical os simulated base 24. The protrusions 234 are hemispherical and protrude from the inner wall of the simulated vagina 23.

[0040] Reference Figure 8 , 10 As shown, the shielding assembly 25 includes a servo motor 251 and a shielding plate 252. The servo motor 251 is mounted on the cervical simulation base 24. The shielding plate 252 is connected to the output end of the servo motor 251, and the output ends of the shielding plate 252 and the servo motor 251 are eccentrically positioned. The servo motor 251 is used to drive the shielding plate 252 to rotate to shield or open the cervical opening of the simulated vagina 23. The cervical simulation base 24 is cylindrical, and a second through hole 241 is provided in the center of the cervical simulation base 24. The servo motor 251 is used to drive the shielding plate 252 to rotate to shield or open the second through hole 241. The second through hole 241 is conical, and the larger end of the second through hole 241 faces the side of the simulated vagina 23.

[0041] Reference Figure 8 , 9 As shown, the distance calculation component 26 includes a motor 261, a first gear 262, a second gear 263, and an encoder 264. The encoder 264 is connected to the second gear 263, the second gear 263 meshes with the first gear 262, the first gear 262 is connected to the output shaft of the motor 261, the insemination gun 3 is in contact with the encoder 264, and the encoder 264 is used to calculate the insertion depth of the insemination gun 3.

[0042] In the above structure, the end of the cervical simulation base 24 away from the simulated vagina 23 is provided with a circular sleeve 242. The center of the circular sleeve 242 is set as a hollow structure. The distance calculation component 26 is set on the circular sleeve 242, and the outer wall of the encoder 264 extends into the center of the circular sleeve 242 and contacts the insemination gun 3. As the insemination gun 3 extends along the circular sleeve 242, it can make frictional contact with the encoder 264. The movement of the insemination gun 3 drives the encoder 264 to rotate. Through the calculation and conversion of the encoder 264, the movement distance of the insemination gun 3 is calculated and converted into the movement distance of the insemination gun 3. The starting end of the micro switch 27 extends into the circular sleeve 242 through the side wall of the circular sleeve 242. When the insemination gun 3 extends forward, when the front end of the insemination gun 3 contacts the micro switch 27, the micro switch 27 is triggered, and the host computer of the training equipment receives the signal.

[0043] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
