Description

Technical Field

[0001] This invention relates to the field of livestock equipment technology, and in particular to a fully automatic semen collection device and system for breeding pigs. Background Technology

[0002] In the pig farming industry, the role of boars is indispensable. The quality of boar semen directly affects the farrowing rate, litter size, and the health of piglets at birth. Furthermore, with the development of the farming industry, artificial semen collection and artificial insemination of boars have become effective means for large-scale farms to improve production efficiency.

[0003] In existing technologies, the specific steps for collecting boar semen are as follows: The boar is induced to mount the prosthetic unit by exploiting its poor eyesight, and the semen is collected by hand. While this hand-gripping method is simple, hygienic, and inexpensive, it neglects the boar's comfort during the collection process. Furthermore, the existing prosthetic unit structure is too simple, consisting entirely of metal components covered with a non-slip, wear-resistant material. It requires inducing semen collection by using secretions or urine from the reproductive tract of a sow in estrus. Moreover, the overall structure of the existing prosthetic unit differs significantly from the sow's shape and is not designed according to the structure of the sow's reproductive organs. This design can lead to boars not mounting the prosthetic unit for extended periods during semen collection and training, or changes in collection methods due to the collector's lack of skill or changes in personnel, causing damage to the boar's reproductive organs. This can lead to boar dissatisfaction, aggression, and frequent incidents of boar attacking personnel. Because the boar's physiological needs are not met, its libido declines, and it stops mounting the prosthetic unit. This situation not only shortens the lifespan of boars but also leads to an increase in boar culling rates and corresponding feeding costs.

[0004] As mentioned above, in existing technologies, the cleaning of the boar's penis before semen collection also requires manual labor. Specifically, the penis must be pulled out of the reproductive organs and manually rinsed before collection. This process is cumbersome and can easily cause stress in the boar. Furthermore, the reproductive organ structure on existing prosthetic units is typically a straight cylindrical structure, which is simple and cannot simulate the internal environment of a real sow's reproductive organs, thus hindering the stimulation of the boar's libido.

[0005] Furthermore, existing technologies also involve fixing the semen collector to the tail of the prosthetic unit, simulating the sow's vaginal environment to stimulate the boar's libido. The prosthetic unit also includes a thermos for collecting semen flowing from the collector. While this eliminates the need for manual intervention during collection, reducing the workload for collectors, the initial semen ejaculation from the boar contains a large amount of useless gelatinous material and may be contaminated with urine, impurities, bacteria, and other substances. This compromises the quality of the collected semen, increasing the difficulty of semen analysis. If this semen is used for artificial insemination of sows, it can lead to culling due to reproductive disorders such as endometritis, increasing sow culling rates and associated feeding costs.

[0006] Existing technologies also disclose automatic semen collection devices. Semen collectors stand on one or both sides of the automatic semen collection device. The automatic semen collection device has a variable channel fence and a prosthetic unit. Below the prosthetic unit, there is a device for fixing the artificial vagina and a bracket for fixing the semen collection cup. In actual operation, the semen collector needs to wear double gloves and stimulate the pig's penis to become erect and ejaculate. During the ejaculation process, the semen collector discards the semen at the beginning of ejaculation and collects the semen afterward. Although this device can distinguish and collect semen in the early stage and the middle and late stages of ejaculation, it still has problems such as complicated operation, high manpower consumption, and high cost.

[0007] Currently, no effective solutions have been proposed for the problems existing in related technologies, such as the complex operation process of semen collection from breeding pigs, the low quality of collected semen, the inability to automatically clean the penis of breeding pigs, and the inability of the reproductive organ structure on the prosthetic unit to simulate the internal environment of the reproductive organs of real sows. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0078] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0079] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the invention.

[0080] Example 1

[0081] An illustrative embodiment of the present invention, such as Figure 1 As shown, a fully automatic boar semen collection device includes a prosthetic unit 100, a vaginal unit 200, an audio unit 300, a collection unit 400, and a control unit 500. The prosthetic unit 100 has an internal cavity element 130; the vaginal unit 200 is located at the tail of the prosthetic unit 100; the audio unit 300 is located at the head of the prosthetic unit 100 and is used to simulate the sounds produced when a sow is in estrus; the collection unit 400 is located within the internal cavity element 130 and is used to collect semen flowing from the end of the vaginal element 220; the control unit 500 is communicatively connected to the vaginal unit 200, the audio unit 300, and the collection unit 400.

[0082] like Figure 2 As shown, the prosthetic unit 100 includes a support element 110 and a placement element 120. The support element 110 is disposed on the prosthetic unit 100 at positions corresponding to the limbs of the prosthetic unit 100, and the support element 110 can be fixed to the floor of the semen collection room by bolts; the placement element 120 is disposed on both sides of the prosthetic unit 100, and when the breeding pig climbs onto the prosthetic unit 100, the breeding pig's forelimbs can step on the placement element 120.

[0083] Specifically, there are four support elements 110, and the four support elements 110 correspond to the four limbs of the prosthesis unit 100 respectively. The four support elements 110 can ensure the stability of the prosthesis unit 100 installation.

[0084] In some of these embodiments, the support element 110 is a support leg.

[0085] Specifically, there are two placement elements 120, and the two placement elements 120 are located on opposite sides of the prosthetic unit 100, and correspond one-to-one with the two forelimbs of the prosthetic unit 100.

[0086] In some of these embodiments, the placement element 120 is a foot pedal.

[0087] It should be noted that the prosthetic unit 100 is made to mimic the shape of a sow, and the surface of the prosthetic unit 100 is coated with rubber paint or epoxy resin coating, so that the shape and structure of the prosthetic unit 100 are more adapted to the physiological needs of the boar and reduce stress response during semen collection.

[0088] In some embodiments, the prosthesis unit 100 further includes a closure element 140. The closure element 140 is hinged to the side of the prosthesis unit 100 and corresponds to the inner cavity element 130 on the prosthesis unit 100, for opening or closing the inner cavity element 130.

[0089] In some of these embodiments, the closure element 140 is a closure cover.

[0090] like Figure 3 , Figure 4 and Figure 5 As shown, the vaginal unit 200 includes a cylindrical element 210, a vaginal element 220, an expansion and contraction element 230, and at least one cleaning element 240. The outer wall of the cylindrical element 210 is connected to the prosthetic unit 100; the vaginal element 220 is disposed around the inner wall of the cylindrical element 210, and the vaginal element 220 can reciprocate in expansion and contraction within the cylindrical element 210, with its end extending into the inner cavity element 130; the expansion and contraction element 230 is disposed between the cylindrical element 210 and the vaginal element 220, and is connected to the control unit 500 for driving the vaginal element 220 to reciprocate in contraction; the cleaning element 240 is installed at the vaginal opening of the cylindrical element 210 for cleaning the penis of the breeding pig when the penis of the breeding pig enters the cylindrical element 210.

[0091] Specifically, the prosthesis unit 100 has an opening inside that can accommodate the vaginal unit 200, and the first end of the opening extends to the tail of the prosthesis unit 100, and the second end of the opening extends to the inner cavity element 130 of the prosthesis unit 100 and communicates with the inner cavity element 130.

[0092] Furthermore, the tubular element 210 can be placed inside the hole, with its sidewall connected to the inner sidewall of the hole in the prosthesis unit 100. The first end of the tubular element 210 extends to the first end of the hole, and the second end of the tubular element 210 extends to the second end of the hole and communicates with the inner cavity element 130 to fix the vaginal unit 200.

[0093] Furthermore, the cylindrical element 210 has a snap-fit ​​groove located near the vaginal opening of the vaginal unit 200, and the snap-fit ​​groove is formed on the inner wall of the cylindrical element 210 and is arranged in an annular groove. It should be noted that the snap-fit ​​groove allows the cleaning element 240 to be detachably connected, that is, when the cleaning element 240 needs to be cleaned or replaced, the cleaning element 240 can be removed from the snap-fit ​​groove for replacement, so as to ensure that the working environment for each semen collection operation meets the semen collection standard.

[0094] In some embodiments, there are multiple snap-fit ​​slots, and each snap-fit ​​slot corresponds one-to-one with a cleaning element 240. Generally, the number of snap-fit ​​slots is the same as the number of cleaning elements 240.

[0095] like Figure 4As shown, the vaginal element 220 includes a vaginal prosthesis 221, a cervical prosthesis 222, and a connecting tube 223. The vaginal prosthesis 221 is disposed around the inner wall of the cylindrical element 210; the cervical prosthesis 222 is disposed around the inner wall of the cylindrical element 210 and communicates with the vaginal prosthesis 221; the first end of the connecting tube 223 communicates with the end of the cervical prosthesis 222, and the second end of the connecting tube 223 extends into the inner cavity element 130 and corresponds to the collecting unit 400.

[0096] It should be noted that both the vaginal prosthesis 221 and the cervical prosthesis 222 are hollow tubular structures, and the vaginal prosthesis 221 and the cervical prosthesis 222 can be connected by splicing, heat fusion fixation or integral molding.

[0097] In some embodiments, the materials of the vaginal prosthesis 221 and the cervical prosthesis 222 include, but are not limited to, silicone, rubber, etc.

[0098] Furthermore, the inner wall of the vaginal prosthesis 221 is pleated, which allows the vaginal prosthesis 221 to simulate the real internal environment of the sow's vagina, which is beneficial to stimulating the sexual desire of the breeding pig.

[0099] Furthermore, the inner wall of the cervical prosthesis 222 is designed with protruding fleshy spheres, which allows the cervical prosthesis 222 to simulate the real internal environment of the sow's cervix. Because the penis of the breeding pig is relatively long, in actual mating, the penis of the breeding pig usually enters the cervix for ejaculation. The real cervix of the sow contains multiple fleshy spheres, which can, to a certain extent, fix the penis of the breeding pig. In this embodiment, the inner wall of the cervical prosthesis 222 is designed with protruding fleshy spheres to simulate the real internal environment of the sow's cervix. When the penis of the breeding pig is inserted into the cervical prosthesis 222, the fleshy spheres on the inner wall of the cervical prosthesis 222 can fix the glans of the penis to a certain extent. After the breeding pig finishes ejaculating, it will automatically withdraw.

[0100] More specifically, the length of the vaginal prosthesis 221 is between 10cm and 15cm, corresponding to the length of the vagina in the sow's reproductive organs.

[0101] More specifically, the length of the cervical prosthesis 222 is between 8cm and 12cm, corresponding to the length of the cervix in the sow's reproductive organs.

[0102] Furthermore, the length of the tubular element 210 is greater than the length of the vaginal element 220, and the inner diameter of the tubular element 210 is greater than the outer diameter of the vaginal element 220.

[0103] The cylindrical element 210 has a length of 120 mm and an inner diameter of 40 mm. The vaginal element 220 has a length of 100 mm and an inner diameter of 30 mm.

[0104] In some embodiments, the length of the cylindrical element 210 may be 100mm, 150mm, etc., and the inner diameter of the cylindrical element 210 may be 30mm, 50mm, etc. The length of the vaginal element 220 may be 80mm, 120mm, etc. It should be noted that the length of a sow's cervix is ​​generally between 100mm and 180mm, and the inner diameter is generally between 15mm and 30mm. Therefore, the dimensions of the cylindrical element 210 and the vaginal element 220 can be selected according to the length and diameter of the sow's cervix and the actual application scenario, without imposing too many restrictions here.

[0105] More specifically, the first end of the connecting tube 223 is connected to the end of the cervical prosthesis 222 by splicing, heat fusion fixing or integral molding, and the second end of the connecting tube 223 is suspended above the collection unit 400.

[0106] The distance between the second end of the connecting tube 223 and the collecting unit 400 is between 1mm and 5mm, which can avoid the situation where the collecting unit 400 is inconvenient to collect data due to the excessive suspension distance between the second end of the connecting tube 223 and the collecting unit 400.

[0107] It should be noted that the two ends of the connecting pipe 223 along its length are the first end and the second end of the connecting pipe 223, respectively.

[0108] In some embodiments, the connecting pipe 223 includes, but is not limited to, a universal flexible hose.

[0109] Furthermore, a contact ring is provided at the vaginal opening corresponding to the cylindrical element 210. The contact ring is made of flexible material. The contact ring makes the boar's penis softer when it comes into contact with the vaginal unit 200, while reducing the physical impact that the boar's activities may cause, thus facilitating the semen collection process.

[0110] Furthermore, the vaginal unit 200 also includes a temperature regulating element 250. The temperature regulating element 250 is disposed between the inner wall of the cylindrical element 210 and the vaginal element 220, and is connected to the control unit 500 to simulate the temperature of a sow's vagina.

[0111] It should be noted that the temperature regulating element 250 generates heat itself and transfers the heat to the vaginal element 220, maintaining the temperature of the vaginal element 220 between 38.0 and 38.7°C. This makes the environment inside the vaginal element 220 more like the real vaginal environment of a sow, thereby increasing the stimulation of the sow's penis by the vaginal element 220.

[0112] In some of these embodiments, the temperature regulating element 250 includes, but is not limited to, heating wires and dry thermostats.

[0113] Furthermore, lubricant can be applied to the inner wall of the vaginal element 220 to ensure that the lubrication inside the vaginal element 220 is similar to the environment inside a real sow's vagina.

[0114] Furthermore, the vaginal unit 200 also includes an object detection element 260. The object detection element 260 is disposed at the vaginal opening of the vaginal unit 220 and connected to the control unit 500, and is used to generate an object signal when the penis of the breeding pig enters the vaginal unit 220, and transmit the object signal to the control unit 500.

[0115] It should be noted that the control unit 500 controls the expansion and contraction element 230 and the temperature regulation element 250 to start synchronously according to the infrared signal transmitted by the object monitoring element 260. This makes the internal environment of the vaginal element 220 as close as possible to the real vaginal environment of a sow. This allows the boar's penis to receive sufficient stimulation in the vaginal element 220, simulating mating. This prompts the boar to ejaculate a large amount of semen in a short time under sufficient and strong stimulation, shortening the collection time and avoiding insufficient stimulation that leads to a small amount of semen collected.

[0116] In some embodiments, the object detection element 260 includes, but is not limited to, a P228 infrared sensor, an LH1958 infrared sensor, an LHI954 infrared sensor, a RE200B infrared sensor, a KDS209 infrared sensor, a PIS209 infrared sensor, an LHI878 infrared sensor, a PD632 infrared sensor, etc.

[0117] like Figure 5 As shown, the expansion and contraction element 230 includes an airbag 231 and an inflation / deflation component 232. The airbag 231 is disposed between the inner wall of the cylindrical element 210 and the vaginal element 220, and encloses the vaginal element 220; the inflation / deflation component 232 is disposed outside the prosthesis unit 100, and is connected to the airbag 231 via an air tube 233, and is also connected to the control unit 500.

[0118] More specifically, the air bladder 231 is filled between the inner wall of the cylindrical element 210 and the vaginal element 220, and is connected to the inner wall of the cylindrical element 210 by adhesive or riveting; and the air bladder 231 wraps the vaginal element 220, so that the expansion and contraction of the air bladder 231 realizes the contraction of the vaginal element 220, thereby making the vaginal element 220 exert a pressure effect on the penis of the breeding pig, promoting the ejaculation efficiency of the breeding pig.

[0119] It should be noted that the airbag 231 and the inflation / deflation component 232 are connected by an air tube 233, and the air tube 233 between the airbag 231 and the inflation / deflation component 232 passes through a hole inside the prosthesis unit 100 and into the inner cavity element 130 of the prosthesis unit 100, thereby realizing the connection between the airbag 231 and the inflation / deflation component 232.

[0120] In some embodiments, airbag 231 includes, but is not limited to, strip airbag.

[0121] More specifically, the inflation / deflation component 232 is installed in the inner cavity element 130 of the prosthesis unit 100 by means of bolts, rivets or adhesives.

[0122] It should be noted that the inflation / deflation device 232 enables rapid inflation and deflation of the airbag 231, meaning that the inflation / deflation time for the airbag 231 to be inflated and deflated by the inflation / deflation device 232 is between 2 and 3 seconds. Furthermore, the inflation / deflation device 232 is connected to the control unit 500, which can control the frequency of inflation and deflation of the airbag 231 via the inflation / deflation device 232, thereby controlling the contraction frequency of the vaginal element 220. For example, the vaginal element 220 may contract once every 20 seconds.

[0123] In some embodiments, the inflation / deflation device 232 includes, but is not limited to, an automatic inflation / deflation machine.

[0124] like Figure 3 As shown, there are several cleaning elements 240, and these cleaning elements 240 are spaced apart along the length of the cylindrical element 210.

[0125] In some embodiments, there are two cleaning elements 240, and the two cleaning elements 240 are spaced apart along the length of the cylindrical element 210, so that the penis of the breeding pig passes through the cleaning elements 240 in sequence, thereby wiping the penis of the breeding pig.

[0126] In some embodiments, in order to increase the cleaning effect of wiping the penis of the breeding pig, the cleaning element 240 may be three, four, etc., that is, the number of cleaning elements 240 can be adaptively selected according to the actual cleaning effect on the penis of the breeding pig, and no further limitation is made here.

[0127] Specifically, the cleaning element 240 includes a retaining ring 241, several elastic flaps 242, and a wiping element 243. The retaining ring 241 is detachably connected to the inner wall of the cylindrical element 210 and is located at the vaginal opening of the vaginal unit 200. The several elastic flaps 242 are connected to the retaining ring 241 and are arranged circumferentially around the retaining ring 241, closing the annular surface of the retaining ring 241. The wiping element 243 is detachably disposed at the end of the corresponding elastic flap 242 and is used to wipe and clean the penis of the breeding pig when the penis passes through the retaining ring 241.

[0128] More specifically, the retaining ring 241 is installed in the snap-fit ​​groove on the inner wall of the cylindrical element 210, and the size of the retaining ring 241 corresponds to the inner diameter of the snap-fit ​​groove of the cylindrical element 210; generally, the outer diameter of the retaining ring 241 is the same as the inner diameter of the snap-fit ​​groove.

[0129] In some of these embodiments, the retaining ring 241 includes, but is not limited to, a rubber ring.

[0130] More specifically, the elastic flaps 242 are connected to the inner wall of the fixing ring 241 by means of heat fusion or bonding, and several elastic flaps 242 seal the annular surface of the fixing ring 241. During the process of the boar penis passing through the fixing ring 241, the boar penis pushes open the elastic flaps 242, and as the boar penis is inserted, the elastic flaps 242 can play a certain role in wiping and cleaning the surface of the boar penis.

[0131] In some embodiments, there are four elastic flaps 242, and each elastic flap 242 has a right-angled fan-shaped structure. The four elastic flaps 242 are arranged around the fixing ring 241 and form a circular surface.

[0132] In some embodiments, there may be 3 or 5 elastic flaps 242, and several elastic flaps 242 are arranged around the fixing ring 241 to form a circular surface. It should be noted that the number of elastic flaps 242 can be adaptively selected according to the resistance encountered by the boar penis when passing through the fixing ring 241, that is, to ensure that the boar penis can pass through smoothly while also cleaning the boar penis in all directions.

[0133] More specifically, the wiping element 243 is fixed to each elastic membrane flap 242 by adhesive bonding, and the wiping element 243 can be pre-soaked in the cleaning solution. When needed, it is taken out of the cleaning solution and bonded to the corresponding elastic membrane flap 242.

[0134] In some of these embodiments, the wiping element 243 includes, but is not limited to, a cleaning cotton ball.

[0135] like Figure 1As shown, the audio unit 300 records the sounds emitted by sows during estrus. When semen collection is being carried out on breeding pigs, the semen collector activates the audio unit 300 through the control unit 500, thereby attracting the breeding pigs to the vicinity of the prosthetic unit 100 and stimulating their sexual desire.

[0136] In some embodiments, the audio unit 300 includes, but is not limited to, MP3, MP4 and loudspeakers.

[0137] like Figure 6 and Figure 7 As shown, the collection unit 400 includes a base element 410, a first fixing element 420, a second fixing element 430, a drive element 440, and a weight monitoring element 450. The base element 410 is disposed within the inner cavity element 130 and is slidably connected to the inner bottom wall of the inner cavity element 130. A first fixing element 420 is disposed on the base element 410 for installing a waste liquid device, which collects semen during the initial ejaculation phase of the boar. A second fixing element 430 is disposed on the base element 410 for installing a liquid storage device, which collects semen during the middle and later stages of ejaculation. A driving element 440 is disposed between the inner bottom wall of the inner cavity element 130 and the base element 410 and is connected to the control unit 500. It drives the base element 410 to reciprocate, allowing the first fixing element 420 and the second fixing element 430 to switch positions at the corresponding ends of the vaginal element 220. A weight monitoring element 450 is mounted on the first fixing element 420 and connected to the control unit 500. It generates a weight signal when the weight of an item on the first fixing element 420 reaches a preset weight threshold and transmits it to the control unit 500.

[0138] Specifically, the base element 410 is a movable plate, and the size of the base element 410 is smaller than the cross-sectional size of the inner cavity element 130, so that the base element 410 does not contact the inner wall of the inner cavity element 130 when it moves within the inner cavity element 130.

[0139] Specifically, the first fixing element 420 is a hollow cylinder, and the end of the first fixing element 420 away from the base element 410 is open, so that the waste liquid device can be installed in the first fixing element 420 through the opening.

[0140] It should be noted that the height of the first fixing element 420 is half the height of the waste liquid device.

[0141] In some embodiments, the first fixing element 420 includes a guiding arc surface. The guiding arc surface is integrally formed at the opening of the first fixing element 420, and the guiding arc surface is inclined in a direction away from the central axis of the first fixing element 420. The guiding arc surface facilitates the installation of the waste liquid device within the first fixing element 420.

[0142] In some embodiments, the first fixing element 420 further includes a first elastic member 421. Two first elastic members 421 are provided within the first fixing element 420, both of which are fixed at the opening of the first fixing element 420 and are positioned opposite each other on the inner sidewall of the first fixing element 420. The first elastic members 421 can press the waste liquid device against the first fixing element 420, thereby increasing the stability of the waste liquid device installation.

[0143] In some of these embodiments, the first elastic element 421 includes, but is not limited to, a retaining ring and an elastic sheet.

[0144] Specifically, the second fixing element 430 is a hollow cylinder, and the end of the second fixing element 430 away from the base element 410 is open, so that the liquid storage device can be installed in the second fixing element 430 through the opening.

[0145] It should be noted that the height of the second fixing element 430 is half the height of the liquid storage device.

[0146] In some embodiments, the second fixing element 430 includes a guiding arc surface. The guiding arc surface is integrally formed at the opening of the second fixing element 430, and the guiding arc surface is inclined in a direction away from the central axis of the second fixing element 430. The guiding arc surface facilitates the installation of the liquid storage device within the second fixing element 430.

[0147] In some embodiments, the second fixing element 430 further includes a second elastic member 431. Two second elastic members 431 are provided within the second fixing element 430, both of which are fixed at the opening of the second fixing element 430 and are positioned opposite each other on the inner sidewall of the second fixing element 430. The second elastic members 431 can press the liquid storage device against the second fixing element 430, thereby increasing the stability of the liquid storage device installation.

[0148] In some of these embodiments, the second elastic element 431 includes, but is not limited to, a retaining ring and an elastic sheet.

[0149] Specifically, the driving element 440 includes a slider 441, a driving element 442, and a transmission element 443. The slider 441 is connected to the bottom of the base element 410; the driving element 442 is disposed within the inner cavity element 130; and the transmission element 443 connects the driving element 442 and the base element 410, transmitting power from the driving element 442 to the base element 410, causing the base element 410 to reciprocate within the inner cavity element 130 via the slider 441.

[0150] Furthermore, four sliders 441 are provided on the base element 410, and the four sliders 441 correspond to the four corners of the base element 410 respectively. The base element 410 can move within the inner cavity element 130 through the sliders 441. It should be noted that placing the sliders 441 at the four corners of the base element 410 can increase the stability of the movement of the base element 410.

[0151] In addition, a groove 411 is provided on the base element 410 at the position corresponding to the slider 441, and the slider 441 is embedded in the groove 411 to ensure that the slider 441 translates along the direction of the connecting line between the first fixing element 420 and the second fixing element 430.

[0152] In some of these embodiments, the slider 441 includes, but is not limited to, a pulley.

[0153] Furthermore, the drive component 442 is fixed to the inner bottom wall of the inner cavity component 130 by means of welding, bolting, riveting or bonding, and the output shaft of the drive component 442 is connected to the transmission component 443.

[0154] In some embodiments, the drive element 442 includes, but is not limited to, a drive motor.

[0155] Furthermore, the transmission component 443 includes a gear 443a and a rack 443b. The gear 443a is coaxially fixed to the output shaft of the drive component 442; the rack 443b is fixed to the bottom wall of the base component 410 by welding, bolting, riveting, or bonding, and the gear 443a and the rack 443b mesh with each other.

[0156] In some embodiments, the transmission component 443 further includes a limiting block 443c, which is integrally formed on both ends of the rack 443b to limit the travel of the base component 410 in reciprocating motion, ensuring that the reciprocating motion of the base component 410 in the inner cavity component 130 can be carried out stably.

[0157] In actual operation, the drive component 442 drives its output shaft to rotate clockwise or counterclockwise, thereby causing the gear 443a to rotate clockwise or counterclockwise. When the toothed section on the rack 443b contacts the gear 443a, the rack 443b is driven to reciprocate through the kneading action, thereby enabling the base component 410 to reciprocate within the inner cavity component 130.

[0158] Specifically, the weight monitoring element 450 is installed on the inner bottom wall of the first fixed element 420 to detect the weight of the semen collected in the waste liquid device 700. When the weight of the semen collected in the waste liquid device 700 reaches a certain threshold, the weight monitoring element 450 transmits a weight signal to the control unit 500. The control unit 500 then controls the drive element 440 based on the weight signal, causing the base element 410 to move, thereby aligning the second fixed element 430 with the second end of the connecting pipe 223. This allows the storage device 800 within the second fixed element 430 to collect semen from the later stages of ejaculation in the breeding pig. Furthermore, after the fully automatic breeding pig semen collection device completes one semen collection operation, the control unit 500 controls the drive element 440 to reset the base element 410 to its initial position and simultaneously resets the weight signal detected by the weight monitoring element 450 to prepare for the next semen collection operation.

[0159] It should be noted that since the ejaculation volume of breeding pigs is between 150ml and 300ml, the preset weight threshold is 50ml. In some embodiments, the preset weight threshold may also be 40ml, 60ml, etc. The preset weight threshold can be set according to the actual ejaculation volume of the breeding pig, and no further restrictions are imposed here.

[0160] In some of these embodiments, the weight monitoring element 450 includes, but is not limited to, photoelectric load cells, hydraulic load cells, capacitive load cells, electromagnetic force load cells, magnetic pole changing load cells, and plate ring load cells.

[0161] like Figure 8 and Figure 9 As shown, the control unit 500 includes a communication element 510 and a control element 520. The communication element 510 is communicatively connected to the object monitoring element 260 of the vaginal unit 200 and the weight monitoring element 450 of the collection unit 400, respectively. The control element 520 is connected to the communication element 510, the vaginal element 220, the expansion and contraction element 230, the audio unit 300, and the collection unit 400, respectively. It is used to acquire the infrared signal transmitted by the object monitoring element 260 and control the vaginal element 220 based on the infrared information; it is also used to acquire the weight signal transmitted by the weight monitoring element 450 and control the collection unit 400 based on the weight signal.

[0162] In some embodiments, the communication element 510 includes, but is not limited to, a Bluetooth sensor, a WiFi sensor, and a ZigBee sensor.

[0163] In some of these embodiments, the control element 520 includes, but is not limited to, an MCU, a Raspberry Pi, or a microcontroller.

[0164] In some embodiments, the control element 520 incorporates an infrared judgment model and a weight judgment model.

[0165] Furthermore, the control unit 500 also includes a power supply element 530. The power supply element 530 is electrically connected to the communication element 510, the control element 520, the inflation / deflation element 232, the audio unit 300, the drive element 442, the weight monitoring element 450, and the object monitoring element 260, respectively, and is used to supply power to the communication element 510, the control element 520, the inflation / deflation element 232, the audio unit 300, the drive element 442, the weight monitoring element 450, and the object monitoring element 260.

[0166] Furthermore, such as Figure 8 As shown, the control unit 500 also includes a console, a display element 540, and several operating elements 550. The communication element 510, the control element 520, and the power supply element 530 are disposed inside the console. The display element 540 is disposed on the surface of the console and connected to the control element 520 to display the current parameters and the current working status. The several operating elements 550 are disposed on the surface of the console and connected to the control element 520 to adjust parameters and send control commands (such as start and stop).

[0167] In some of these embodiments, the display element 540 includes, but is not limited to, an LCD display, an OLED display, and an e-ink display.

[0168] The method of using this invention is as follows:

[0169] (a) Preparation

[0170] First, the personnel cleaned and dried the vaginal element 220 and replaced the connecting tube 223 at the end of the vaginal element 220 to ensure that the inside of the vaginal element 220 was clean.

[0171] Subsequently, the wiping element 243 removed from the cleaning solution is attached to the elastic diaphragm flap 242, and the retaining ring 241 is installed into the snap-fit ​​groove to realize the installation of the cleaning element 240;

[0172] Secondly, lubricant is dripped into the vaginal element 220 to simulate the moist environment inside the sow's vagina, thereby further stimulating the penis of the breeding pig by the vaginal element 220.

[0173] Then, the sealing element 140 on the prosthesis unit 100 is opened, and the waste liquid device 700 and the liquid storage device 800 are installed on the first fixing element 420 and the second fixing element 430, respectively.

[0174] Finally, shut down the sealing element 140 to prepare for data acquisition.

[0175] (ii) Cleaning

[0176] When the breeding pig crawls onto the prosthetic unit 100, the object monitoring element 260 senses the approach of the breeding pig and generates an infrared signal that is transmitted to the control unit 500. The control unit 500 activates the temperature regulating element 250, which generates heat and transfers the heat to the vaginal element 220, maintaining the temperature of the vaginal element 220 between 38.0 and 38.7°C. This makes the environment inside the vaginal element 220 more like the real vaginal environment of a sow, thereby increasing the stimulation of the breeding pig's penis by the vaginal element 220.

[0177] During the process of the boar's penis entering the vaginal opening of the vaginal unit 200 and passing through the fixing ring 241, the boar's penis pushes open the elastic membrane flap 242. As the boar's penis is inserted, both the elastic membrane flap 242 and the wiping element 243 can wipe and clean the surface of the boar's penis.

[0178] (III) Operation

[0179] When the pig's penis enters the vaginal element 220, the control unit 500 activates the inflation / deflation device 232. The inflation / deflation device 232 repeatedly inflates and deflates the air sac 231 (i.e., the inflation / deflation device 232 inflates the air sac 231 for 2 seconds and holds it for 2 seconds, then deflates the air sac 231 for 2 seconds, and after an interval of 14 seconds, the inflation / deflation device 232 inflates and deflates the air sac 231 again, and so on). This causes the air sac 231 to expand and contract, thereby causing the vaginal element 220 to contract. This allows the vaginal element 220 to exert pressure on the pig's penis, promoting the pig's ejaculation efficiency.

[0180] (iv) Collection

[0181] Initially, the base element 410 aligns the first fixing element 420 with the second end of the connecting tube 223, and the waste liquid device 700 inside the first fixing element 420 collects the semen of the boar at the beginning of ejaculation.

[0182] After the weight of the semen collected in the waste liquid device 700 reaches a certain threshold, the weight monitoring element 450 transmits the weight signal to the control unit 500, and the control unit 500 controls the second driving element 440 according to the weight signal, so that the base element 410 moves, thereby aligning the second fixing element 430 with the second end of the connecting tube 223, and thus the liquid storage device 800 in the second fixing element 430 collects the semen in the middle and late stages of the ejaculation of the breeding pig.

[0183] After the semen collection operation is completed on the breeding pig, the semen collector removes the liquid storage device 800 from the inner cavity element 130;

[0184] Subsequently, the base element 410 is reset to its initial position on the control panel (that is, the waste liquid device 700 on the first fixed element 420 is aligned with the end of the connecting pipe 223), so that the fully automatic boar semen collection device can perform the next semen collection operation.

[0185] The advantages of this invention are that by simulating the real environment of a sow's vagina through the vaginal element 220, the breeding pig can simulate the real mating environment as much as possible during semen collection, reducing the discomfort of the breeding pig during the semen collection process and providing sufficient stimulation, thereby reducing the training time for boar semen collection; in addition, by simulating the real vaginal environment of a sow through the vaginal element 220, the overall operational difficulty of the semen collection process can be reduced, and the labor intensity of the semen collection personnel can be reduced; the cleaning element 240 can also clean the breeding pig's penis while it is inserted into the vaginal element 220, ensuring the hygiene standards of the entire semen collection process; and the semen from the initial ejaculation stage and the subsequent ejaculation stages can be collected separately. Since the initial ejaculation of the breeding pig may contain substances such as urine, separate collection can ensure higher quality semen and improve the success rate of subsequent mating.

[0186] Example 2

[0187] This embodiment relates to the fully automated semen collection system for breeding pigs of the present invention.

[0188] like Figure 10 , Figure 11 and Figure 12 As shown, a fully automated boar semen collection system includes a fence device 600, a fully automated boar semen collection device as described in Example 1, a waste liquid device 700, and a liquid storage device 800. The fully automated boar semen collection device is housed within the fence device 600; the waste liquid device 700 is installed on the fully automated boar semen collection device and is used to collect semen from the initial ejaculation of the boar; the liquid storage device 800 is installed on the fully automated boar semen collection device and is used to collect semen from subsequent ejaculations of the boar.

[0189] like Figure 11As shown, the fencing device 600 includes an entrance 610 and an exit 620. The entrance 610 and exit 620 of the fencing device 600 are positioned opposite each other, and both the entrance 610 and exit 620 are equipped with openable and closable fences. These fences allow the breeding pigs to be confined during semen collection, preventing them from becoming agitated or irritable during the process. This effectively restrains the pigs and protects the semen collection personnel.

[0190] In some embodiments, the entrance 610 and the exit 620 may also be located on the same side of the fence device 600, that is, one half of any side of the fence device 600 is the entrance 610 and the other half is the exit 620.

[0191] It should be noted that the fence device 600 is 2.5m long, 1.5m wide, and 1m high.

[0192] In some embodiments, the length of the fence device 600 may be 2m or 3m, the width of the fence device 600 may be 1m or 2m, and the height of the fence device 600 may be 1.3m or 1.5m.

[0193] Furthermore, the fence at the entrance 610 and the exit 620 of the fence device 600 is equipped with locking devices. The locking devices can lock the fence at the entrance 610 and the exit 620 of the fence device 600 to the main body of the fence device 600, which can prevent the breeding pig from colliding and causing the breeding pig to get out of control.

[0194] Furthermore, the fence device 600 also includes a side opening 630 (the side opening 630 is the operating port). The side opening 630 is located on the corresponding closure element 140 of the prosthesis unit 100 of the fence device 600. The side opening 630 facilitates the installation or removal of the waste liquid device 700 and the liquid storage device 800 by the semen collection personnel on the outside of the fence device 600, further improving the operational safety of the semen collection personnel.

[0195] The method of using this invention is as follows:

[0196] During semen collection, the breeding pigs are driven from the pigpen to the entrance 610 of the fence device 600, and the fence at the entrance 610 is opened to allow the breeding pigs to enter the fence device 600.

[0197] Subsequently, after completing the semen collection operation on the breeding pig through the operating port, the exit 620 of the fence device 600 is opened, and the breeding pig is driven back into the pigpen. The above operation is repeated to carry out continuous semen collection operations on multiple breeding pigs.

[0198] The above description is merely a preferred embodiment of the present invention and does not limit the implementation and protection scope of the present invention. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
