Description

Technical Field

[0001] This invention belongs to the field of breeding technology for breeding pigs, and in particular relates to a precise identification auxiliary system and method for breeding new breeds of breeding pigs. Background Technology

[0002] Breeding pigs are not a separate species, but rather male (boars) and female (sows) parent pigs specifically used for reproduction among domestic pigs. The selection of breeding pigs requires consideration of pedigree data, bloodline characteristics, paternal index, maternal index, and body shape and appearance. It also involves selecting and mating pigs based on their paternal index, maternal index, physical characteristics, and areas for improvement, combining homogeneous and heterogeneous selection.

[0003] In the process of selecting breeding pigs for export based on body shape, it is necessary to check the number of teats, weigh the individual pigs, and check for genetic defects. However, because breeding pigs are more excited under human intervention, users cannot easily check their weight and number of teats. The identification process requires a lot of human intervention before and after identification, which consumes a lot of time and energy and is prone to identification errors. Therefore, it is necessary to provide a precise identification auxiliary system and method for breeding new pig breeds. The system first corrects the body position of the breeding pig and restricts its activity. At the same time, it takes pictures of the abdomen of the breeding pig through mirror reflection, so that users can accurately check the number of teats. It is also equipped with a separation structure, which can separate the selected breeding pigs for penning, thereby improving the efficiency of selection. Summary of the Invention

[0004] The purpose of this invention is to provide a precise identification auxiliary system and method for breeding new pig breeds. The system first corrects the body position of the breeding pig and restricts its activity. At the same time, it uses a mirror reflection method to photograph and record the abdomen of the breeding pig, so that the user can accurately check the number of teats. It is also equipped with a separation structure, which can separate the selected breeding pigs for pen rearing, thereby improving the breeding efficiency and solving the above-mentioned technical problems.

[0005] The technical solution of this invention to solve the above-mentioned technical problems is as follows: A method for precise identification of new breeds of breeding pigs, which is applied to an auxiliary system for precise identification of new breeds of breeding pigs. The system includes a breeding platform located above a base plate: an electronic scale is fixedly installed in the inner cavity of the breeding platform; guardrails are fixedly connected to the front and rear sides of the top of the breeding platform; cameras are fixedly installed on opposite sides of the two guardrails; the platform of the electronic scale is an ultra-clear tempered glass mirror; a correction component is provided on the front side of the breeding platform; a displacement component is provided below the breeding platform; the displacement component includes a fixing plate fixedly connected to the front and rear sides of the breeding platform; a first threaded rod is provided below the breeding platform; the first threaded rod... Both ends are rotatably connected to the fixed plate via bearings. A threaded sleeve rotatably connected to the base plate is provided below the breeding platform. The threaded sleeve is threaded to the surface of the first threaded rod. A second stepper motor is fixedly installed on the top of the base plate below the breeding platform. A drive gear is fixedly connected to the output shaft of the second stepper motor. A force-bearing gear is fixedly connected to the surface of the threaded sleeve. The force-bearing gear and the drive gear mesh. Support wheels are installed at the four corners of the bottom of the breeding platform. The support wheels roll in contact with the top of the base plate. Rectangular grooves are opened on the front and rear sides of the top of the breeding platform. A scraping component is provided on the top of the breeding platform. A propulsion component is provided on the bottom of the breeding platform.

[0006] The method for precise identification and breeding of this new pig breed is as follows:

[0007] The user first drives the breeding pig to be identified to the top of the selection platform and measures its weight using an electronic scale to check if it meets the selection requirements. Then, the first stepper motor is turned on. The first stepper motor drives two drive bevel gears to rotate through the drive rod. Under the meshing transmission of the drive bevel gear and the force bevel gear, the two deflection rods on the front side rotate in opposite directions, causing the two correction rods to rotate and rise above the selection platform. During the rising of the correction rods, the two correction rods move between the fore and hind limbs of the breeding pig, thus restraining the pig and preventing it from moving.

[0008] At the same time, the camera filmed the abdomen of the breeding pig through the reflection of the top of the electronic scale, so that the number of teats on the bottom of the breeding pig could be viewed through electronic instruments, thereby checking the number and arrangement angle of the breeding pig's teats. Then, the first stepper motor rotated in reverse, causing the drive rod, drive bevel gear and force bevel gear to rotate in reverse, thereby causing the correction rod to fall back and release the breeding pig from the limit.

[0009] Subsequently, based on the identification results, the definite breeding pigs can be housed in different pig pens. At this time, the second stepper motor is turned on and drives the drive gear to rotate. Under the meshing transmission of the drive gear and the force gear, the threaded sleeve rotates. During the rotation of the threaded sleeve, through the cooperation of its inner wall thread and the surface thread of the first threaded rod, the first threaded rod drives the selection platform to slide back and forth through the fixed plate, so that the right side of the selection platform reaches the left side of the designated guide channel, allowing the breeding pigs to enter the inner cavity of the corresponding guide channel for separate pen feeding.

[0010] After a period of use, to prevent the reflective effect on the top of the electronic scale from becoming contaminated, surface dirt can be wiped off. During wiping, the user activates the third stepper motor, which drives the second threaded rod to rotate. The second threaded rod, through its surface threads, pushes the slide carriage forward. During this pushing process, the slide carriage, through the cooperation of the fixing pin and connecting plate, drives the sliding sleeve to move. Guided by the pulley and guide groove, the sliding sleeve first rises and then slides to the right. During this sliding process, under the arc tension of the fixing arm and rotating arm, the scraper presses against the top of the electronic scale and scrapes it to the right, finally allowing the dirt to detach from the top of the electronic scale, enabling the top of the electronic scale to reflect a clearer image again.

[0011] Preferably, the correction component includes deflection rods rotatably connected to the front and rear ends of the breeding platform, and a correction rod rotatably connected between the two deflection rods on the same side. The surface of the guardrail is provided with an arc-shaped groove adapted to the correction rod.

[0014] Preferably, the scraping assembly includes a sliding sleeve located on the top left side of the selection platform, a fixed arm is fixedly connected to the top of the inner cavity of the sliding sleeve, and a rotating arm is rotatably connected to both the front end and the rear end of the fixed arm.

[0015] Preferably, scrapers are fixedly connected to the bottom of the two rotating arms, and the scrapers are rubber scrapers.

[0016] Preferably, the propulsion assembly includes a third stepper motor installed on the left side of the bottom of the selection platform. The output shaft of the third stepper motor is fixedly connected to a second threaded rod. The right end of the second threaded rod is rotatably connected to the selection platform through a bearing. A slide is threadedly connected to the surface of the second threaded rod.

[0017] Preferably, the front and rear sides of the bottom of the sliding sleeve are fixedly connected to connecting plates, the connecting plates are slidably connected to the inner cavity of the rectangular slide groove, and pulleys are rotatably connected to the opposite sides of the two connecting plates. The inner cavity of the rectangular slide groove near the electronic scale is provided with guide arc grooves adapted to the pulleys, and the pulleys are rotatably connected to the inner cavity of the guide arc grooves.

[0018] Preferably, the front and rear sides of the top of the carriage are fixedly connected with fixing pins, and the connecting plate is slidably connected to the surface of the fixing pins.

[0034] Figure 1-7This invention illustrates a method for precise identification of new breeds of breeding pigs, applied to an auxiliary system for precise identification of new breeds of breeding pigs. The system includes a breeding platform 1 located above a base plate. An electronic scale 2 is fixedly installed inside the breeding platform 1. A driving channel 10, fixedly connected to the base plate, is located on the left side of the electronic scale 2. Guide channels 11, fixedly connected to the base plate, are located at the front and rear ends of the right side of the breeding platform 1. Guardrails 3 are fixedly connected to the front and rear sides of the top of the breeding platform 1. Cameras 9 are fixedly installed on opposite sides of the two guardrails 3. The platform surface of the electronic scale 2 is a super-clear tempered glass mirror. A correction component 4 is located on the front side of the breeding platform 1. A displacement component 5 is located below the breeding platform 1. The displacement component 5 includes a fixing plate 51 fixedly connected to the front and rear sides of the breeding platform 1. A... The first threaded rod 52 has two ends rotatably connected to the fixed plate 51 via bearings. A threaded sleeve 53 rotatably connected to the base plate is provided below the breeding platform 1. The threaded sleeve 53 is threaded to the surface of the first threaded rod 52. A second stepper motor 54 is fixedly installed on the top of the base plate below the breeding platform 1. A drive gear 56 is fixedly connected to the output shaft of the second stepper motor 54. A force-bearing gear 55 is fixedly connected to the surface of the threaded sleeve 53. The force-bearing gear 55 and the drive gear 56 mesh with each other. Support wheels 57 are installed at the four corners of the bottom of the breeding platform 1. The support wheels 57 roll in contact with the top of the base plate. Rectangular grooves 6 are opened on the front and rear sides of the top of the breeding platform 1. A scraping component 7 is provided on the top of the breeding platform 1. A pushing component 8 is provided on the bottom of the breeding platform 1.

[0035] The method for precise identification and breeding of this new pig breed is as follows:

[0036] The user first drives the breeding pig to be identified to the top of the breeding platform 1 and measures the weight of the breeding pig using the electronic scale 2 to check whether the weight of the breeding pig meets the breeding requirements. Then, the first stepper motor 44 is turned on. The first stepper motor 44 drives the two drive bevel gears 46 to rotate through the drive rod 45. Under the meshing transmission of the drive bevel gears 46 and the force bevel gears 47, the two deflection rods 41 located on the front side rotate in opposite directions, so that the two correction rods 42 rotate and rise above the breeding platform 1. During the rising process of the correction rods 42, the two correction rods 42 move between the fore and hind limbs of the breeding pig, so that the breeding pig is restrained and prevented from moving.

[0037] At the same time, the camera 9 takes pictures of the abdomen of the breeding pig through the refraction of the top of the electronic scale 2, so that the number of teats on the bottom of the breeding pig can be viewed through electronic instruments, thereby checking the number and arrangement angle of the breeding pig's teats. Then, the first stepper motor 44 rotates in the opposite direction, causing the drive rod 45, the drive bevel gear 46 and the force bevel gear 47 to rotate in the opposite direction, thereby causing the correction rod 42 to fall back and release the breeding pig from the limit.

[0038] Subsequently, based on the identification results, the definite breeding pigs can be kept in different pigsties. At this time, the second stepper motor 54 is turned on and drives the drive gear 56 to rotate. Under the meshing transmission of the drive gear 56 and the force gear 55, the threaded sleeve 53 rotates. During the rotation of the threaded sleeve 53, through the cooperation of its inner wall thread and the surface thread of the first threaded rod 52, the first threaded rod 52 drives the breeding platform 1 to slide back and forth through the fixing plate 51, so that the right side of the breeding platform 1 reaches the left side of the designated guide channel 11, so that the breeding pigs can enter the inner cavity of the corresponding guide channel 11 and be raised in separate pens.

[0039] After a period of use, to prevent the reflective effect on the top of the electronic scale 2 from becoming contaminated, surface dirt can be wiped off. During wiping, the user turns on the third stepper motor 81, which drives the second threaded rod 82 to rotate. The second threaded rod 82 pushes the slide 83 through its surface threads. During the pushing process, the slide 83, through the cooperation of the fixing pin 87 and the connecting plate 84, drives the sliding sleeve 71 to move. Guided by the pulley 85 and the guide arc groove 86, the sliding sleeve 71 first rises and then slides to the right. During the sliding process, under the arc tension of the fixing arm 72 and the rotating arm 73, the scraper 74 is pressed against the top of the electronic scale 2 and scraped to the right. Finally, the dirt is removed from the top of the electronic scale 2, so that the top of the electronic scale 2 can reflect a clearer image again. Example 2

[0040] Similar to Embodiment 1, but further: the correction component 4 includes deflection rods 41 rotatably connected to the front and rear ends of the selection platform 1; a correction rod 42 is rotatably connected between the two deflection rods 41 on the same side; the surface of the guardrail 3 has an arc-shaped groove 43 adapted to the correction rod 42; a first stepper motor 44 is fixedly installed at the right end of the front side of the selection platform 1; a drive rod 45 is fixedly connected to the output end of the first stepper motor 44; drive bevel gears 46 are fixedly connected to both sides of the surface of the drive rod 45; and a force-bearing bevel gear 47 is fixedly connected to one end of the two deflection rods 41 on the front side. Both sides of the moving rod 45 are rotatably connected to the breeding platform 1 via bearings, driving bevel gear 46 and force bevel gear 47 mesh with each other. Through the setting of the correction component 4, driven by the first step motor 44 and with the cooperation of the driving rod 45 and the driving bevel gear 46, the two force bevel gears 47 rotate in opposite directions. During the rotation of the force bevel gears 47, the deflection rod 41 drives the correction rod 42 to rotate, thereby correcting the position of the limbs of the breeding pig, and thus making the abdomen of the breeding pig completely exposed on the top of the electronic scale 2, thereby improving the clarity and accuracy of the camera 9. Example 3

[0041] Similar to Embodiment 1, but further: the scraping component 7 includes a sliding sleeve 71 located on the top left side of the selection platform 1. A fixed arm 72 is fixedly connected to the top of the inner cavity of the sliding sleeve 71. Rotating arms 73 are rotatably connected to the front and rear ends of the fixed arm 72. Scrapers 74 are fixedly connected to the bottom of the two rotating arms 73. The scrapers 74 are rubber scrapers. Through the arrangement of the scraping component 7, the fixed arm 72 and the rotating arm 73 work together to provide elastic support for the scraper 74, so that the scraper 74 has a certain elastic squeezing force after contacting the top of the electronic scale 2, thereby improving the cleaning ability of the dirt on the top of the electronic scale 2. Example 4

[0042] Similar to Embodiment 1, but further: the propulsion assembly 8 includes a third stepper motor 81 installed on the left side of the bottom of the selection platform 1.

The connecting plates 84 are slidably connected to the inner cavity of the rectangular slide groove 6. A pulley 85 is rotatably connected to the opposite side of the two connecting plates 84. A guide adapted to the pulley 85 is provided on the side of the inner cavity of the rectangular slide groove 6 near the electronic scale 2. The arc groove 86 and pulley 85 are rolled in the inner cavity of the guide arc groove 86. The front and rear sides of the top of the slide 83 are fixedly connected with fixing pins 87. The connecting plate 84 is slidably connected to the surface of the fixing pins 87. With the setting of the push assembly 8, driven by the third stepper motor 81 and the cooperation of the second threaded rod 82 and the slide 83, the fixing pin 87 can drive the connecting plate 84 and the sliding sleeve 71 to slide. Then, the sliding sleeve 71 can drive the scraper 74 to scrape the top of the electronic scale 2 through the fixed arm 72 and the rotating arm 73, so that the dirt on the top of the electronic scale 2 can be removed, thereby ensuring the clarity of the video recorded by the camera 9.

[0043] In summary, this precision identification auxiliary system and method for breeding new pig breeds measures the weight of the breeding pigs using an electronic scale 2, detects the number of teats using a correction component 4 and a camera 9, separates the identified breeding pigs using a displacement component 5 and a guide channel 11, and finally cleans the top of the electronic scale 2 using a scraping component 7 and a pushing component 8. This system facilitates the detection of the condition and quality of the abdominal teats and enables automatic separation and penning.
