Description

Technical Field

[0001] This invention belongs to the field of slaughtering equipment technology, and in particular relates to an automatic hoof scraping device. Background Technology

[0002] Pig hooves are generally divided into left, middle, and right hooves. The hair inside the crevices of the left, middle, and right hooves is very difficult to remove. Currently, the market has very high requirements for the quality of pig hooves. Pig hooves sold should have almost no pig hair residue, otherwise, it will lead to customer complaints or a lower selling price. However, the process of removing hair from pig hooves has always been a challenge in the slaughtering industry.

[0003] The most common process in slaughterhouses is scalding and dehairing followed by rosin dipping. These two processes can remove over 90% of the hair from pig hooves. However, a small amount of remaining hair, especially inside the hoof, still requires extensive manual removal, which is quite difficult. The hoof needs to be pried open, and handheld blade-type scrapers cannot easily reach deep into the crevices, resulting in some hooves not being completely cleaned even after manual scraping. This process is energy-intensive. Rosin dipping equipment, in particular, is labor-intensive, inefficient, and may leave rosin residue on the cross-section of the pig's hoof, affecting food safety. Some pig hooves are dehaired using singeing or branding, but these processes cause the hooves to turn yellow due to high temperatures, affecting quality, and produce a pungent odor, posing a higher safety risk.

[0004] Therefore, designing a simple, automated device that can remove the hair from pig hooves while ensuring their quality, while being simple, efficient, and reducing energy consumption and labor costs, has become a key research topic in this field. Summary of the Invention

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides an automatic hoof hair removal device, which is an automated hair removal device that not only reduces energy consumption, but also removes hair cleanly, saves manpower, and greatly reduces production costs.

[0006] To achieve the above objectives, this invention discloses an automatic hoof scraping device, comprising a frame, on which are mounted a feeding and positioning mechanism, a left hoof scraping mechanism, a middle hoof scraping mechanism, and a right hoof scraping mechanism. The feeding and positioning mechanism includes a fixing clamp for securing the hoof and a positioning clamp for positioning the hoof, and also includes a first driving device for rotating the fixing clamp. The left hoof scraping mechanism includes a left hoof scraping blade and a second driving device for driving the left hoof scraping blade to move up, down, left, and right. The middle hoof scraping mechanism includes a middle hoof scraping blade... The hoof hair removal mechanism includes a hair removal blade and a third driving device for driving the middle hoof hair removal blade to move up and down and back and forth. The right hoof hair removal mechanism includes a right hoof hair removal blade and a fourth driving device for driving the right hoof hair removal blade to move up and down and left and right. It also includes a fifth driving device for driving the left hoof hair removal blade, the middle hoof hair removal blade and the right hoof hair removal blade to rotate respectively. When the first driving device drives the fixed clamp to rotate, the pig hoof passes through the left hoof hair removal mechanism, the middle hoof hair removal mechanism and the right hoof hair removal mechanism respectively to remove the pig hair inside the hoof.

[0007] According to the present invention, an automatic hoof scraping device is provided, which fixes and positions the pig hoof through a feeding and positioning mechanism; the feeding and positioning mechanism is rotated by a first driving device, which drives the fixing clamp to rotate; when the fixing clamp rotates to the left hoof scraping mechanism, the left hoof scraping mechanism scrapes off the hair in the left hoof crevices of the pig hoof; when the fixing clamp rotates to the middle hoof scraping mechanism, the middle hoof scraping mechanism scrapes off the hair in the middle hoof crevices of the pig hoof; when the fixing clamp rotates to the right hoof scraping mechanism, the right hoof scraping mechanism scrapes off the hair in the right hoof crevices of the pig hoof. Specifically, the fifth drive device will rotate the left hoof scraper, the middle hoof scraper, and the right hoof scraper. The second, third, and fourth drive devices will respectively drive the left hoof scraper, the middle hoof scraper, and the right hoof scraper to move up and down, left and right, up and down, forward and backward, and up and down, left and right, so that the left hoof scraper, the middle hoof scraper, and the right hoof scraper can be inserted into the hoof crevices of the left hoof, the middle hoof, and the right hoof, respectively, to scrape off the pig hair inside the hoof crevices.

[0008] In addition, the technical solution provided by the present invention may also have the following technical features:

[0009] In any of the above technical solutions, the fixing clamp includes a support plate for supporting pig hooves, a pressure plate for pressing the pig hooves on the support plate, and a first cylinder for driving the pressure plate to rise and fall, so that when the piston rod of the first cylinder rises, the pressure plate moves away from the support plate, and when the piston rod of the first cylinder falls, the pressure plate moves closer to the support plate.

[0010] In this technical solution, pig hooves are placed on a support plate and pressed against the support plate by a pressure plate, thereby fixing the pig hooves. Specifically, when the piston rod of the first cylinder rises, it moves the pressure plate away from the support plate, thus placing the pig hooves in. When the piston rod of the first cylinder falls, it moves the pressure plate closer to the support plate, thus pressing the pig hooves and fixing them.

[0011] In any of the above technical solutions, the positioning fixture includes a second cylinder, a positioning plate connected to the second cylinder, and a positioning head connected to the positioning plate, so that when the piston rod of the second cylinder extends, the positioning head is inserted into the middle hoof of the pig's hoof.

[0012] In this technical solution, the positioning fixture is mounted on the frame, and the positioning plate moves back and forth via a second cylinder. Specifically, to ensure that the left hoof scraper, middle hoof scraper, and right hoof scraper can be accurately inserted into the hoof crevices, the position and angle of the pig's hoof on the support plate need to be positioned. In other words, when the pig's hoof is placed on the support plate, the second cylinder is opened, and the piston rod of the second cylinder extends to drive the positioning head to check whether it can be inserted into the middle hoof. If it can be inserted, the positioning is completed, and the next step can be performed. If it cannot be inserted, the angle and position of the pig's hoof are adjusted. Only after the pig's hoof is positioned can the next step be performed.

[0013] In any of the above technical solutions, the second driving device includes a left hoof scraping support frame, a left hoof lifting cylinder mounted on the left hoof scraping support frame, and a left hoof front and rear cylinder connected to the left hoof lifting cylinder. The left hoof front and rear cylinder is connected to the left hoof scraping knife through a first floating mechanism.

[0014] In this technical solution, the left hoof scraper moves up and down via a left hoof lifting cylinder, and moves left and right via a left hoof front and rear cylinder. A first floating mechanism allows the left hoof scraper to float during the scraping process. Specifically, when the left hoof scraper is inserted into the hoof, it adapts to the width of the hoof crevices to scrape away the hair within.

[0015] In any of the above technical solutions, the first floating mechanism includes a base, a slide rail disposed on the base, and a slider that matches the slide rail. One side of the slider is connected to a first elastic device, and the other side is connected to a blade holder for mounting the left hoof scraper. When the left hoof scraper is subjected to force, the pressure is transmitted to the blade holder, causing the blade holder to drive the slider to move along the slide rail, pulling the first elastic device and realizing the floating of the left hoof scraper.

[0016] In this technical solution, the base is connected to the front and rear cylinders of the left hoof. A slide rail is provided on the base, and the slider is connected to the first elastic device. The first elastic device is connected to the blade holder for mounting the left hoof scraper. During operation, when the left hoof scraper is inserted into the hoof crevices, it will be subjected to the pressure of the hoof. This pressure will be transmitted to the slider through the blade holder, causing the slider to move along the slide rail. When the slider moves, it will pull the first elastic device, thereby generating elastic force in the first elastic device. When the pressure is less than the elastic force, the first elastic device will drive the slider to reset, that is, drive the blade holder to reset. The blade holder will then move back and forth, thus realizing the floating of the left hoof scraper.

[0017] In any of the above technical solutions, the third driving device includes a hoof scraping support frame, a hoof lifting cylinder mounted on the hoof scraping support frame, and a hoof front and rear cylinder connected to the hoof lifting cylinder. The hoof front and rear cylinders are connected to the hoof scraping knife through a second floating mechanism.

[0018] In this technical solution, the hoof scraper moves up and down through a hoof lifting cylinder, moves back and forth through a hoof front and rear cylinder, and floats during the scraping process through a second floating mechanism.

[0019] In any of the above technical solutions, a third floating mechanism is provided between the first floating mechanism and the left hoof scraper, and between the second floating mechanism and the middle hoof scraper, so that the left hoof scraper or the middle hoof scraper can tilt and float when inserted into the hoof of the pig's hoof.

[0020] In this technical solution, the third floating mechanism causes the left hoof scraper or the middle hoof scraper to float after being subjected to force, thereby ensuring that the left hoof scraper or the middle hoof scraper can penetrate into the hoof crevices and scrape the hair inside the hoof crevices cleanly.

[0021] In any of the above technical solutions, the third driving device further includes a lifting mechanism for lifting the hoof part of the pig's hoof.

[0022] In this technical solution, the hoof end of the pig's hoof is lifted by the lifting structure, so that it tilts upward and the hoof seam of the middle hoof naturally opens, thus matching the tilt angle of the middle hoof scraping knife, making it easier for the middle hoof scraping knife to be inserted into the hoof in the knife.

[0023] In any of the above technical solutions, the right hoof scraping mechanism and the left hoof scraping mechanism have the same structure, and the left hoof scraping knife and the right hoof scraping knife are located on the left side and the right hoof scraping knife is located on the right side relative to the fixing clamp.

[0024] In this technical solution, the right hoof hair removal mechanism and the left hoof hair removal mechanism have the same structure. The difference between the two is that, relative to the fixed clamp, the right hoof hair removal knife is on the right side of the fixed clamp, and the left hoof hair removal knife is on the left side of the fixed clamp, thereby removing the hair in the hoof crevices of the left and right hooves.

[0025] In any of the above technical solutions, a feeding mechanism for pushing pig trotters out of the frame is also included.

[0026] In this technical solution, the feeding mechanism facilitates the ejection of the pig's trotters after the hair has been scraped off from the fixed clamp, so as to transport the pig's trotters to the designated position. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0035] This invention provides an automatic hoof hair removal device, referring to... Figure 1-2As shown, the device includes a frame 1, on which are mounted a feeding and positioning mechanism 2, a left hoof scraping mechanism 3, a middle hoof scraping mechanism 4, and a right hoof scraping mechanism 5. The feeding and positioning mechanism 2 includes a fixing clamp 20 for fixing the pig's hoof and a positioning clamp 21 for positioning the pig's hoof, and also includes a first driving device for driving the fixing clamp 20 to rotate. The left hoof scraping mechanism 3 includes a left hoof scraping blade 30 and a second driving device 31 for driving the left hoof scraping blade 30 to move up, down, left, and right. The middle hoof scraping mechanism 4 includes a middle hoof scraping blade 40 and a second driving device 31 for driving the middle hoof scraping blade 30 to move up, down, left, and right. The hoof scraping blade 40 has a third drive device 41 for moving up, down, forward, and backward. The right hoof scraping mechanism 5 includes a right hoof scraping blade 50 and a fourth drive device 51 for driving the right hoof scraping blade 50 to move up, down, left, and right. It also includes a fifth drive device 6 for driving the left hoof scraping blade 30, the middle hoof scraping blade 40, and the right hoof scraping blade 50 to rotate respectively. When the first drive device drives the fixed clamp 20 to rotate, the pig's hoof passes through the left hoof scraping mechanism 3, the middle hoof scraping mechanism 4, and the right hoof scraping mechanism 5 respectively to scrape the pig hair inside the hoof. Among them, the left hoof scraping blade 30, the middle hoof scraping blade 40, and the right hoof scraping blade 50 are all conical blades.

[0036] In use, the feeding and positioning mechanism 2 is used to fix and position the pig's hooves, and the first driving device is used to rotate the feeding and positioning mechanism 2. The first driving device is set inside the frame 1 and includes a drive motor and a cam divider connected to the drive motor. There are 8 fixed clamps 20, which are connected to the cam divider respectively. The cam divider and the fixed clamps 20 divide the equipment into 8 workstations, namely 1 feeding and positioning workstation, 2 left hoof scraping workstations, 2 middle hoof scraping workstations, 2 right hoof scraping workstations, and 1 unloading workstation. Each time the drive motor rotates, it will drive the fixed clamps 20 to move the pig's hooves to one workstation. Preferably, the left hoof hair removal blades 30 in the two left hoof hair removal stations have different diameters. The larger diameter left hoof hair removal blade 30 can work in the wider hoof seam, while the smaller diameter left hoof hair removal blade 30 can work in the narrower hoof seam, thus ensuring that the hair in the hoof seam is cleanly removed. The right hoof hair removal blades 50 in the two right hoof hair removal stations have different diameters, and the design principle is the same as that of the left hoof hair removal blade 30. The middle hoof hair removal blades 40 in the two middle hoof hair removal stations rotate in opposite directions. The forward rotation of the middle hoof hair removal blade 40 cleans one side of the pig hair in the hoof seam, and the reverse rotation of the middle hoof hair removal blade 40 cleans the other side of the pig hair in the hoof seam.

[0037] More specifically, a preferred workstation sequence is as follows: First, the pig's trotters are fixed to the feeding and positioning station, where the feeding and positioning mechanism 2 positions and fixes the trotters. Then, the drive motor drives the fixing clamp 20 to rotate via the cam divider. When the clamp reaches the left hoof scraping station, the drive motor stops rotating, and the fifth drive device 6 drives the left hoof scraping blade 30 to rotate at high speed. The second drive device 31 drives the left hoof scraping blade 30 to move up, down, left, and right, allowing it to insert into the hoof crevices and scrape off the pig hair. After a certain period, the drive... The motor continues to rotate, sending the fixed clamp 20 to another left hoof scraping station to remove pig hair from the hoof crevices. After these two scraping stations, it is ensured that the pig hair in the hoof crevices of the left hoof is completely removed. Then, the drive motor continues to rotate, sending the fixed clamp 20 to the middle hoof scraping station. The drive motor stops rotating, and the fifth drive device 6 drives the middle hoof scraping knife 40 to rotate at high speed. The third drive device 41 drives the middle hoof scraping knife 40 to move up and down and back and forth, so that the middle hoof scraping knife 40 is inserted into the hoof crevices of the middle hoof and scrapes off the pig hair in the crevices. Similarly, the drive motor continues to rotate, sending the fixing clamp 20 to the next hoof scraping station, ultimately removing all the pig hair from the hoof crevices of the hoof. Finally, the drive motor continues to operate, sending the fixing clamp 20 to the right hoof scraping station. The drive motor stops rotating, and the fifth drive device 6 drives the right hoof scraping blade 50 to rotate at high speed. The fourth drive device 51 drives the right hoof scraping blade 50 to move up, down, left, and right, causing it to insert into the hoof crevices of the right hoof and scrape off the pig hair. Similarly, the drive motor continues to rotate, sending the fixing clamp 20 to the next right hoof scraping station, ultimately removing all the pig hair from the hoof crevices of the right hoof.

[0038] It should be noted that, apart from the fixed loading and positioning station, the order of other stations can be adjusted arbitrarily according to the order. At the same time, the unloading station and stations with the same function can also be added or removed as needed.

[0039] Following the above embodiments, a more preferred solution includes a feeding station to remove the pig's trotter from the fixing clamp 20. The feeding station includes a feeding mechanism 7, which facilitates the removal of the scraped-off pig's trotter from the fixing clamp 20, transporting the trotter to a designated location. More specifically, the feeding mechanism 7 includes a feeding cylinder 71 and a push plate 72 connected to the feeding cylinder 71. When the fixing clamp 20 reaches the feeding station, the fixing clamp 20 opens, the piston rod of the feeding cylinder 71 extends, and the push plate 72 pushes the pig's trotter out of the fixing clamp 20. Preferably, the push plate 72 has a circular groove structure that matches the pig's trotter. When the feeding cylinder 71 operates, the circular groove can wrap around the end of the pig's trotter, stably pushing it out.

[0040] It should be noted that the right hoof hair removal mechanism 5 and the left hoof hair removal mechanism 3 have the same structure. The difference between the two is that, relative to the fixed clamp 20, the right hoof hair removal knife 50 is on the right side of the fixed clamp 20, and the left hoof hair removal knife 30 is on the left side of the fixed clamp 20, thereby removing the hair from the crevices of the left and right hooves.

[0041] Following the above embodiments, a more specific solution is that the fixing clamp 20 includes a support plate 201 for supporting the pig's hoof, a pressure plate 202 for pressing the pig's hoof on the support plate 201, and a first cylinder 203 for driving the pressure plate 202 to rise and fall. When the piston rod of the first cylinder 203 rises, it drives the pressure plate 202 away from the support plate 201 to open the pig's hoof. When the piston rod of the first cylinder 203 falls, it drives the pressure plate 202 closer to the support plate 201 to press the pig's hoof, thereby fixing the pig's hoof.

[0042] Following the above embodiment, a more specific solution is that the positioning clamp 21 includes a second cylinder 210, a positioning plate 211 connected to the second cylinder 210, and a positioning head 212 connected to the positioning plate 211. When the piston rod of the second cylinder 210 extends, the positioning head 212 is inserted into the middle hoof shell of the pig's hoof. The positioning clamp 21 is set on the frame 1. The positioning plate 211 is driven to move back and forth by the second cylinder 210. The upper and lower surfaces of the positioning head 212 are triangular cone heads, so that the positioning head 212 matches the hoof shell seam, making it easier for the positioning head 212 to enter the hoof shell seam. Specifically, in order to ensure that the left hoof scraper 30, the middle hoof scraper 40, and the right hoof scraper 50 can be accurately inserted into the hoof crevices, the position and angle of the pig's hoof on the support plate 201 need to be positioned. In other words, when the pig's hoof is placed on the support plate 201, the piston rod of the second cylinder 210 extends to drive the positioning head 212 to check whether it can be inserted into the middle hoof. If it can be inserted, the positioning is completed and the next step can be carried out. If it cannot be inserted, the angle and position of the pig's hoof are adjusted. Only after the pig's hoof is positioned can the next step be carried out.

[0043] Following the above embodiments, a more specific solution is as follows: Figure 3As shown, the second driving device 31 includes a left hoof scraping support frame 310, a left hoof lifting cylinder 311 mounted on the left hoof scraping support frame 310, and a left hoof front and rear cylinder 312 connected to the left hoof lifting cylinder 311. The left hoof front and rear cylinder 312 is connected to the left hoof scraping blade 30 through a first floating mechanism. The left hoof lifting cylinder 311 enables the left hoof scraping blade 30 to move up and down, the left hoof front and rear cylinder 312 enables the left hoof scraping blade 30 to move left and right, and the first floating mechanism allows the left hoof scraping blade 30 to float during the scraping process. When the left hoof scraping blade 30 is inserted into the hoof, it adapts to the width of the hoof seam to scrape away the hair within. More specifically, the first floating mechanism includes a base 313, a slide rail 314 disposed on the base 313, and a slider 315 matched with the slide rail 314. One side of the slider 315 is connected to a first elastic device 316, and the other side is connected to a blade holder 317 for mounting a left hoof scraper. When the left hoof scraper 30 is subjected to force, the pressure is transmitted to the blade holder 317, causing the blade holder 317 to drive the slider 315 to move along the slide rail 314, pulling the first elastic device 316, thereby realizing the floating of the left hoof scraper 30.

[0044] In use, the base 313 is connected to the front and rear cylinders 312 of the left hoof. A slide rail 314 is provided on the base 313, and a slider 315 is provided on the slide rail 314. The slider 315 is connected to the first elastic device 316, which is connected to the blade holder 317 for mounting the left hoof scraper 30. When the left hoof scraper 30 is inserted into the hoof crevices, it will be subjected to the pressure of the hoof. This pressure will be transmitted to the slider 315 through the blade holder 317, causing the slider 315 to move on the slide rail 314. When the slider 315 moves, it will pull the first elastic device 316, thereby generating an elastic force in the first elastic device 316. When the pressure is less than the elastic force, the first elastic device 316 will drive the slider 315 to reset, that is, drive the blade holder 317 to reset. At this time, the blade holder 317 moves in the opposite direction of the first movement. In this way, the blade holder 317 will move back and forth, thereby realizing the floating of the left hoof scraper 30.

[0045] It should be noted that the first elastic device 316 may include a slide rod, a slide rod seat, and a spring fitted on the slide rod. The slide rod seat is installed on the base 313. When the slider 315 moves on the slide rail 314, it will drive the slide rod to compress the spring on the slide rod, causing the spring to generate elastic force. That is, the elastic force will generate a pulling force on the slider 315. When the pulling force is greater than the pressure on the slider 315, the slider 315 will move in the opposite direction, ultimately realizing the floating of the left hoof scraper 30.

[0046] Following the above embodiments, a more specific solution is as follows: Figure 4As shown, the third driving device 41 includes a hoof scraping support frame 410, a hoof lifting cylinder 411 mounted on the hoof scraping support frame 410, and a hoof front and rear cylinder 412 connected to the hoof lifting cylinder 410. The hoof front and rear cylinder 412 is connected to the hoof scraping blade 40 via a second floating mechanism. The hoof lifting cylinder 411 enables the hoof scraping blade 40 to move up and down, the hoof front and rear cylinder 412 enables the hoof scraping blade 40 to move back and forth, and the second floating mechanism enables the hoof scraping blade to float during the scraping process. More specifically, the second floating mechanism may include a second elastic device 413. The structure of the second elastic device 413 can be the same as that of the first elastic device 316, and will not be described further.

[0047] Following the above embodiment, a more preferred solution is that, in order to allow the left hoof scraping blade 30, the middle hoof scraping blade 40, and the right hoof scraping blade 50 to more accurately enter the hoof crevices of the middle hoof and improve the scraping effect, the left hoof scraping blade 30, the middle hoof scraping blade 40, and the right hoof scraping blade 50 are respectively inclined relative to the pig's hoof on the fixing clamp 20, and their inclination angle matches the hoof crevices of the pig's hoof. By inclining the left hoof scraping blade 30, the middle hoof scraping blade 40, and the right hoof scraping blade 50, and ensuring that the inclination angle matches the middle hoof of the pig's hoof, the middle hoof scraping blade can more accurately enter the hoof crevices, thus improving the scraping effect.

[0048] Following the above embodiment, a more preferred solution is that a third floating mechanism 8 is provided between the first floating mechanism and the left hoof scraper 30, and between the second floating mechanism and the middle hoof scraper 40, so that the left hoof scraper 30 or the middle hoof scraper 40 can tilt and float when inserted into the hoof of the pig's hoof. Specifically, as... Figure 3 and Figure 4 As shown, the third floating mechanism 8 includes a tension spring 81, a cutter shaft 82, and a cutter shaft support 83. The cutter shaft support 83 is rotatably connected to the cutter shaft 82. For example, the cutter shaft 82 is mounted on the rotating shaft mounting hole of the cutter shaft support 83 via a rotating shaft 84. One side of the cutter shaft 82 is connected to the cutter shaft support 83 via the tension spring 81. When the cutter shaft 82 is under force, it can rotate relative to the cutter shaft support 83 via the rotating shaft 84. Simultaneously, the rotation of the cutter shaft 82 generates tension or pressure on the tension spring 81, thereby allowing the cutter shaft 82 to float and rotate. It should be noted that the hoof crevices of pigs have a flared structure, gradually narrowing towards the inside. The floating rotation of the cutter shaft 82 allows it to adapt to the size of the hoof crevices, enabling it to fit snugly against the surface of the crevices. This allows the scraping blade on the cutter shaft 82 to better remove pig hair from the crevices, improving scraping efficiency and effectiveness. Since the right hoof scraping mechanism 5 and the left hoof scraping mechanism 3 have the same structure, the third floating mechanism 8 also exists in the right hoof scraping mechanism 5, which will not be described in detail here.

[0049] Following the above embodiments, a more preferred embodiment is that the third driving device 41 further includes a lifting mechanism 42 for lifting the hoof portion of the pig's hoof. The lifting mechanism 42 includes a top plate and a lifting cylinder, so that when the piston rod of the lifting cylinder extends, it drives the top plate to rise, lifting the pig's hoof. Specifically, by lifting the hoof end of the pig's hoof through the lifting mechanism 42, causing it to tilt upwards, the hoof suture of the middle hoof naturally opens, making it easier for the middle hoof scraping knife 40 to be inserted into the hoof suture.

[0050] Following the above embodiments, in a more specific embodiment, the fifth drive device 6 includes a cutter motor 61, a synchronous pulley 62, and a synchronous belt 63. The cutter motor 61 drives the synchronous pulley shaft to rotate via a cutter motor coupling. The synchronous pulley shaft is mounted on a synchronous fixing frame via synchronous pulley bearings. Multiple synchronous pulleys 62 are mounted on the synchronous fixing frame and connected to each other via a synchronous belt 63. The synchronous pulleys 62 are connected to a cutter holder 317 via flexible shafts. A left hoof scraper 30, a middle hoof scraper 40, and a right hoof scraper 50 are respectively mounted on the cutter holder 317.

[0051] When the cutter motor 61 is working, it drives the synchronous pulley shaft to rotate through the cutter motor coupling, which in turn drives the synchronous pulley 62 to rotate. Since multiple synchronous pulleys 62 are connected by a synchronous belt 63, multiple synchronous pulleys 62 rotate. Each synchronous pulley 62 is connected to a cutter holder 317 through a flexible shaft. Thus, the rotation of the cutter holder 317 drives the left hoof scraper 30, the middle hoof scraper 40, and the right hoof scraper 50 to rotate. In other words, multiple cutter holders 317 can be rotated by one cutter motor 61, which in turn drives multiple left hoof scrapers 30, middle hoof scrapers 40, and right hoof scrapers 50 to rotate, thereby achieving the scraping of hair off pig hooves.

[0052] It should be noted that the cutter motor 61 is located at the upper end of the frame 1 because the feeding positioning mechanism 2, the left hoof scraping mechanism 3, the middle hoof scraping mechanism 4 and the right hoof scraping mechanism 5 need to be cleaned frequently. Therefore, placing the cutter motor 61 at the upper end of the frame 1 can prevent potential safety hazards.

[0053] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
