Description

Technical Field

[0001] The invention relates to the technical field of animal husbandry, and in particular to a simulated boar for improving sow mating efficiency. Background Art

[0002] With the popularization of artificial insemination technology for pigs, most farms currently use artificial insemination for breeding. According to incomplete statistics, the rate of artificial insemination in China is about 90% or more in large and medium-sized breeding pig farms, and about 70% or more in small breeding pig farms. This technology has greatly saved the cost of boar breeding, accelerated the improvement of pig breeds, and effectively controlled the spread of diseases. However, compared with natural mating, artificial insemination also has some problems. For example, during mating, boars and sows will have a series of "foreplay behaviors" before mating, which generally lasts for 3-5 minutes; in addition, after the boar mounts, some sensitive parts of the boar's body that fit with the sow's body (lower back, reproductive tract and related parts) will stimulate the sow's sexual desire, thereby increasing the sow's sexual sensitivity, prompting the sow's pituitary gland to release posterior pituitary hormones to promote the contraction of the sow's uterus, which is more conducive to the absorption of semen and makes insemination smoother. However, during the artificial insemination process, due to the lack of stimulation from the boar, the sow's uterus is not excited enough, and it is easy to have problems such as uterine failure to absorb sperm and mating failure.

[0003] At present, in artificial insemination of pigs, the sows’ abdomen, flanks, breasts, buttocks, groin, vulva and back parts with sparse hair and soft skin are usually stimulated 3-5 minutes before insemination. Commonly used methods are: rubbing (flanks, buttocks), kneading (lower abdomen), supporting (breasts), pinching (vulva), pressing (back), etc. In addition, it is necessary to pay attention to the appropriate massage force and to carry out breeding operations in time after the massage to avoid sow fatigue. This operation process is not only time-consuming and labor-intensive, but also difficult to improve the breeding efficiency of the breeding unit.

[0004] There are also existing models of simulated boars, but they have a simple structure, few functions, and are troublesome to use. When the sow moves, the boar cannot move with the sow, which cannot meet people's needs. Therefore, it is necessary to study a simulated boar that can improve the efficiency of sow mating.

DETAILED DESCRIPTION

For this purpose, this embodiment provides a simulated boar that can truly simulate the actions during natural insemination, and the specific structure is as follows.

[0031] like Figure 1 As shown, the simulated boar includes a simulated trunk 1, a head unit 2, a forelimb unit, a support unit and a control unit; each structure is described as follows:

[0032] The head unit 2 is arranged at the front side of the simulated torso 1, and an audio device and an odor device are arranged in the head unit 1; the audio device and the odor device produce the sound and odor of natural mating of sows, truly simulating the scene of natural insemination and increasing the excitement of the sows.

The roots of the left forelimb 3 and the right forelimb 4 are hinged on both sides of the simulated trunk 1. The ends of the left forelimb 3 and the right forelimb 4 are provided with flexible massage teeth 13. The massage teeth 13 improve the contact strength between the left forelimb and the right forelimb and the side of the sow. The upper inner sides of the left forelimb 3 and the right forelimb 4 are correspondingly provided with a left driving seat 31 and a right driving seat 41. The left driving seat 31 and the right driving seat 41 are at different heights. The driving mechanism includes a forelimb motor, a driving disk 11, a left driving rod 32 and a right driving rod 42; the forelimb motor is arranged in the simulated torso 1 and is drivingly connected to the rotating shaft 12 of the driving disk, the eccentric side of the driving disk 11 is provided with a left driving shaft 33 and a right driving shaft 43 which are symmetrical with respect to the center of the driving disk, the two ends of the left driving rod 32 are respectively hinged on the left driving shaft 33 and the left driving seat 31; the two ends of the right driving rod 42 are respectively hinged on the right driving shaft 43 and the right driving seat 41; Figure 2 As shown, when the driving disc 11 rotates clockwise, the left forelimb 3 and the right forelimb 4 are clamped inwardly, and when it rotates counterclockwise, the left forelimb 3 and the right forelimb 4 are opened outwardly.

[0034] The support unit includes a fine-tuning mechanism, a telescopic support rod and a fixed seat 7; the fine-tuning mechanism includes an upper fixed seat 18, a lower fixed seat 19 and an adjusting rod 20, the upper fixed seat 18 is fixed to the rear bottom of the simulated torso 1, and two telescopic support rods are fixed to the bottom of the lower fixed seat 19, and the upper and lower ends of the adjusting rod 20 are respectively hinged on the upper fixed seat 18 and the lower fixed seat 19 to form a parallelogram mechanism. In this embodiment, the upper fixed seat 18, the lower fixed seat 19 and the adjusting rod 20 are connected to form a parallelogram body structure, and tension springs 21 are arranged at the two diagonal positions of the parallelogram mechanism. The tension springs 21 keep the parallelogram in a certain shape, the lower fixed seat is in a fixed state, and the upper fixed seat The position of the simulated torso can be fine-tuned by adjusting the rod and the tension spring to adapt to the movements of the sow. Specifically, when the sow moves forward, the simulated torso 1 will move forward and press the sow's back downward. A fixed seat is arranged at the bottom of the telescopic support rod, and the telescopic support rod comprises a sleeve rod 5 and a sleeve 6. The sleeve rod 5 is sleeved in the sleeve 6 and can be locked. There are many ways to connect the sleeve rod and the sleeve, such as a top screw and a locking sleeve. The top screw runs through the sleeve rod and the sleeve, or the sleeve is pressed by the locking sleeve to generate friction between the sleeve and the sleeve rod, which plays a supporting role in the process of simulated mating of the simulated boar. The telescopic support rod can adjust the model boar to a suitable position according to the height of the sow during insemination, so that the sow is in the best excited state.

[0035] In this embodiment, a suction cup 8 is provided at the bottom of the fixed seat 7, and the bottom of the telescopic support rod is fixed to the ground by the suction cup 8. The position of the simulated torso is adjusted only by the parallelogram mechanism. It is suitable for tilting with a small range of sow movement, such as confining the sow in a pen to restrict its movement.

[0036] like Figure 7 As shown, the control unit includes a MEMS chip, a microprocessor, a forelimb motor, a vibration unit, an audio device and an odor device; the MEMS chip is arranged in the simulated trunk and connected to the signal input end of the microprocessor, the vibration unit is arranged in the simulated trunk, and can generate vibration stimulation to the back of the sow, and the audio device, the odor device, the vibration unit and the forelimb motor are all connected to the signal output end of the microprocessor. Before and during the breeding of the model boar, pressing this button can release the boar odor; pressing the audio button can play the boar breeding call; the vibration button can adjust the frequency; the switch button can preset the breeding time, and can also terminate the operation in advance. The vibration unit can play an action similar to the boar constantly climbing and ejaculating during artificial insemination of the sow.

[0037] In this embodiment, the MEMS chip is installed in the simulated torso, and the simulated torso will have an impact on the movement of the sow. The MEMS chip can detect the sow's movement signals and make corresponding movement feedback according to the movement signals. Specifically, when the sow moves forward or backward, the MEMS chip receives the signal and controls the forelimb motor to drive the left and right forelimbs to clamp. When the sow is in a stable state, the left and right forelimbs are opened. The audio equipment and the smell equipment can continue to work after the boar model is adjusted.

[0038] Embodiment 2: This embodiment is basically the same as Embodiment 1, except that the suction cup is replaced with a walking mechanism in this embodiment.

[0040] During the specific implementation of this embodiment, the movements of the sow are sensed by the MEMS chip. When the movement amplitude of the sow exceeds the threshold, the processor controls the rotation speed of the right limb walking motor and the left limb walking motor, and then adjusts the position of the boar model to adapt to the position of the sow. Specifically, the rotation speed of the right limb walking motor and the left limb walking motor can be adjusted respectively. When the right limb walking motor and the left limb walking motor are at the same speed, the boar model moves forward or backward. When the right limb walking motor and the left limb walking motor are at different speeds, the boar model turns left or right. This embodiment can allow the sow to have larger movements. When the sow's movement amplitude is within the threshold, the walking mechanism is in a shutdown state.
