Description

Technical Field

[0001] The present invention relates to the technical field of livestock processing, and particularly to a hair removal device for beef cattle slaughtering with an adjustable hanging knife angle. Background Art

[0002] In the field of beef cattle slaughtering and processing, efficient and thorough hair removal of carcasses is a key link to ensure the hygienic quality of meat. At present, large-scale slaughterhouses generally use mechanized hair removal equipment for basic processing. These equipment complete the large-area hair removal operation of the cattle body through the movement of scrapers along a preset path, while manual processing is still required for complex parts. Although this combination of mechanization and manual labor has become the industry standard, there are still obvious limitations in the existing equipment when dealing with the main parts of cattle bodies of different sizes.

[0003] There are mainly two prominent defects in the existing mechanized hair removal devices: one is the insufficient angle adaptability of the scrapers. Most equipment can only perform fixed-angle or limited-range adjustment, and it is difficult to accurately fit the contour curves of various parts of the cattle body, resulting in poor large-area fur removal effect; the other is that the fixing and flipping mechanism of the cattle body is not perfect. During the hair removal operation, the displacement operation of the cattle body is cumbersome and time-consuming, seriously affecting the continuity and overall efficiency of the slaughter operation. These technical bottlenecks directly restrict the improvement of the automation level in the slaughter and processing link. Summary of the Invention

[0004] The purpose of the present invention is to solve the defects existing in the prior art, and to propose a hair removal device for beef cattle slaughtering with an adjustable hanging knife angle.

[0005] In order to achieve the above purpose, the present invention adopts the following technical scheme: A hair removal device for beef cattle slaughtering with an adjustable hanging knife angle, including a support frame. A fixed frame is fixedly connected to the top of the support frame. A collection groove communicating with the inside of the support frame is opened at the bottom of the fixed frame. A lifting mechanism is arranged in the collection groove. Fixed blocks are fixedly connected to both sides of the fixed frame, and clamping mechanisms connected to the fixed frame are arranged on both of the fixed blocks. A U-shaped frame is fixedly connected to the top of the fixed frame. A first sliding groove is opened at the top of the U-shaped frame, and a moving frame is slidably connected in the first sliding groove through a first driving mechanism. A second hydraulic cylinder is fixedly connected to the top of the moving frame. The telescopic end of the second hydraulic cylinder penetrates through the moving frame and is fixedly connected to a connecting block. A moving frame is fixedly connected to the bottom of the connecting block. An installation frame is slidably connected in the moving frame through a second driving mechanism. A rotating block is rotatably connected in the installation frame. A second single-head motor for driving the rotating block to rotate is installed on the installation frame. A hair removal mechanism is connected to the bottom of the rotating block.

[0006] As a further improvement of the present invention, the lifting mechanism includes a third hydraulic cylinder fixedly connected to the bottom of the support frame. The telescopic end of the third hydraulic cylinder is fixedly connected to a plate. A movable plate is provided above the plate. A groove is provided at the bottom of the movable plate. The top of the plate is embedded and fixed in the groove.

[0007] As a further improvement of the present invention, the clamping mechanism includes a first hydraulic cylinder fixedly connected to the top of the fixed block. The telescopic end of the first hydraulic cylinder is fixedly connected to a telescopic column. The other end of the telescopic column passes through one side of the fixed frame and is rotatably connected to a rotating plate. One side of the rotating plate is fixedly connected to a mounting plate, and one side of the mounting plate is fixedly connected to a pin.

[0008] As a further improvement of the present invention, the first driving mechanism includes support plates fixedly connected to the top two sides of the U-shaped frame. Two threaded rods are rotatably connected to the two support plates. The movable frame is threadedly connected to the two threaded rods respectively. A connecting rod is fixedly connected to the same end of each of the two threaded rods. The other end of each of the two connecting rods passes through the support plate and is rotatably connected to a support frame. The support frame is fixedly connected to the side wall of the U-shaped frame. Worm gears are fixedly sleeved on the two connecting rods. A double-headed motor is fixedly connected to the top of one side of the U-shaped frame. Worms are fixedly connected to the two output shaft ends of the double-headed motor. The two worms are rotatably connected to the support frame respectively, and the two worms mesh with the two worm gears respectively.

[0009] As a further improvement of the present invention, the second driving mechanism includes a guide groove disposed in a movable frame, a lead screw rotatably connected in the guide groove, a movable block threadedly connected to the lead screw slidably disposed in the guide groove, a mounting bracket fixedly connected to the bottom of the movable block, and a first single-head motor for driving the lead screw to rotate fixedly connected to one side of the movable frame.

[0010] As a further improvement of the present invention, the hair removal mechanism includes a mounting block fixedly connected to the bottom of the rotating block, and a mounting groove is provided on one side of the mounting block. A scraper is detachably mounted in the mounting groove by a plurality of fixing bolts.

[0011] As a further improvement of the present invention, telescopic rods are fixedly connected to both sides of the bottom of the mobile frame, and second sliding grooves are opened on both sides of the top of the U-shaped frame located in the first sliding groove. The telescopic ends of the two telescopic rods pass through the two second sliding grooves respectively and are fixedly connected to the connecting block.

[0012] As a further improvement of the present invention, a through groove is provided on one side of the support frame, and a collection box is inserted into both sides of the through groove, with the two collection boxes located on both sides of the movable plate respectively.

[0013] As a further improvement of the present invention, two flip blocks are respectively hinged to the top two sides of the fixed frame.

[0014] The beneficial effects of this invention are: By employing a clamping mechanism consisting of a rotating plate, a telescopic column, and a first hydraulic cylinder, coupled with a lifting mechanism (including a moving plate and a insert plate) driven by a third hydraulic cylinder, the cattle carcass can be quickly secured and easily flipped. After shaving one side of the hair, the moving plate can be lowered to suspend the cattle carcass in the air. Then, by rotating the rotating plate with external force, the cattle carcass can be flipped. Afterward, the moving plate can be raised again to stabilize the cattle carcass for working on the other side. This design effectively solves the problems of difficult cattle carcass flipping and safety hazards in traditional methods, simplifies the operation process, and improves work efficiency.

[0015] By incorporating an angle adjustment mechanism for the rotating block driven by a second single-head motor, and a lateral movement mechanism for the lead screw and moving block driven by a first single-head motor, the scraper can be flexibly adjusted with multiple degrees of freedom. The scraper can not only perform longitudinal scraping motion driven by the threaded rod via the moving frame, but also adjust its working angle and lateral position. This ensures that the scraper's blade can better adapt to the contour curves of different parts of the cow's body, achieving more comprehensive scraping coverage, effectively improving the cleanliness and uniformity of hair removal, and reducing damage to the hide.

[0016] By incorporating a hair collection system consisting of a collection trough, a collection box, and a through-channel, and by installing an openable flip-top block at the top of the fixed frame, the cleanliness and maintenance of the working environment are optimized. Scraped hair falls through the collection trough into the collection box below for easy cleaning; the flip-top block provides convenient access for cleaning and maintenance of the internal components. This design helps maintain a hygienic work area and reduces the subsequent cleaning burden on operators.

[0017] This invention achieves rapid fixation and safe flipping of the cattle carcass through the coordinated operation of a flip-up clamping mechanism and a lifting mechanism; at the same time, the multi-degree-of-freedom precision adjustment system of the scraper effectively improves the cleanliness and uniformity of the hair removal operation, significantly improving the efficiency and quality of slaughtering and processing.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Figures 1-7A dehairing device for beef cattle slaughter with adjustable hanging knife angle includes a support frame 1, which constitutes the main load-bearing structure of the device. A fixed frame 3 is fixedly connected to the top of the support frame 1 by welding. The fixed frame 3 is used as a working platform. Two flip blocks 7 are hinged to the top two sides of the fixed frame 3 by hinges 8. The flip blocks 7 can be opened outward to facilitate the maintenance and cleaning of the equipment. A collection groove 38 is opened at the bottom of the fixed frame 3 and communicates with the inside of the support frame 1. The scraped hair can fall into the inside of the support frame 1 through the collection groove 38. A lifting mechanism is provided in the collection groove 38 to lift the cattle carcass to a certain height after dehairing on one side for easy transfer.

[0022] The lifting mechanism includes a third hydraulic cylinder 39 fixedly connected to the bottom of the support frame 1. The third hydraulic cylinder 39 provides the power required for the lifting action. A plate 42 is fixedly connected to the telescopic end of the third hydraulic cylinder 39. The plate 42 moves vertically with the telescopic end of the third hydraulic cylinder 39. A movable plate 40 is provided above the plate 42. The movable plate 40 is used to directly support the cow's body. A groove 41 is opened at the bottom of the movable plate 40. The top of the plate 42 is embedded and fixed in the groove 41. Through this connection method, when the plate 42 is driven to rise by the third hydraulic cylinder 39, it can drive the movable plate 40 to rise together. A through groove 2 is opened on one side of the support frame 1. A collection box 4 is inserted into both sides of the through groove 2. The collection box 4 is used to collect and store the hair scraped off the cow's body. The two collection boxes 4 are located on both sides of the movable plate 40 to effectively collect the hair falling from both sides of the cow's body.

[0023] Fixed blocks 5 are fixedly connected to both sides of the fixed frame 3. Each fixed block 5 is equipped with a clamping mechanism connected to the fixed frame 3. The clamping mechanism is used to fix the position of the cow during the hair removal process to prevent it from moving. The clamping mechanism includes a first hydraulic cylinder 6 fixedly connected to the top of the fixed block 5. The first hydraulic cylinder 6 serves as the power source for the clamping action. A telescopic column 9 is fixedly connected to the telescopic end of the first hydraulic cylinder 6. The telescopic column 9 transmits the linear thrust generated by the first hydraulic cylinder 6 to the clamping component. The other end of the telescopic column 9 passes through one side of the fixed frame 3 and is rotatably connected to a rotating plate 10. Through the rotatability of the rotating plate 10, the clamping mechanism can rotate with the help of external force after clamping the cow, thereby flipping the cow over and scraping the hair on the other side. A mounting plate 11 is fixedly connected to one side of the rotating plate 10. A pin 12 is fixedly connected to one side of the mounting plate 11. The pin 12 achieves effective fixation by piercing the skin of the cow.

[0024] A U-shaped frame 13 is fixedly connected to the top of the fixed frame 3 by welding. A first sliding groove 14 is provided on the top of the U-shaped frame 13. A movable frame 20 is slidably connected in the first sliding groove 14 by a first driving mechanism. The movable frame 20 can reciprocate along the length of the first sliding groove 14. Telescopic rods 22 are fixedly connected to both sides of the bottom of the movable frame 20. The telescopic rods 22 play an auxiliary guiding and stabilizing role when the movable frame 20 moves. A second sliding groove 15 is provided on both sides of the top of the U-shaped frame 13 located in the first sliding groove 14. The telescopic ends of the two telescopic rods 22 pass through the two second sliding grooves 15 respectively and are fixedly connected to the connecting block 23 to provide additional support.

[0025] The first driving mechanism includes support plates 16 fixedly connected to both sides of the top of the U-shaped frame 13. The support plates 16 are used to mount transmission components. Two threaded rods 17 are rotatably connected to the two support plates 16. The moving frame 20 is threadedly connected to the two threaded rods 17 respectively. The moving frame 20 is driven to move smoothly by synchronously rotating the two threaded rods 17. A connecting rod 34 is fixedly connected to the same end of each of the two threaded rods 17. The connecting rod 34 is used to transmit power. The other end of each connecting rod 34 passes through the support plate 16 and is rotatably connected to a support frame 19. The support frame 19 provides support and consists of two short plates and one long plate. A short plate is vertically fixed to the long plate, and a support frame 19 is fixedly connected to the side wall of the U-shaped frame 13. Worm gears 36 are fixedly sleeved on two connecting rods 34. A double-headed motor 18 is fixedly connected to the top of one side of the U-shaped frame 13. The double-headed motor 18 can synchronously drive the transmission systems on both sides. Worms 35 are fixedly connected to the two output shaft ends of the double-headed motor 18. The two worm gears 35 are rotatably connected to the support frame 19. The two worm gears 35 mesh with the two worm gears 36 respectively. The two worm gears 35 transmit the power of the motor to the corresponding worm gears 36. The transmission of motion is achieved through the worm gears 36 and worm gears 35, and it has a self-locking function.

[0026] A second hydraulic cylinder 21 is fixedly connected to the top of the movable frame 20. The telescopic end of the second hydraulic cylinder 21 passes through the movable frame 20 and is fixedly connected to a connecting block 23. The second hydraulic cylinder 21 controls the lifting and lowering of the connecting block 23. A movable frame 24 is fixedly connected to the bottom of the connecting block 23. The connecting block 23 drives the lifting and lowering of the movable frame 24. A mounting frame 28 is slidably connected inside the movable frame 24 through a second drive mechanism. The second drive mechanism includes a guide groove 26 set inside the movable frame 24. A lead screw 37 is rotatably connected inside the guide groove 26. A movable block 27 threadedly connected to the lead screw 37 is slidably provided inside the guide groove 26. The movable block 27 slides along the guide groove 26 under the drive of the lead screw 37. The mounting frame 28 is fixedly connected to the bottom of the movable block 27 and moves together with the movable block 27. A first single-head motor 25 that drives the lead screw 37 to rotate is fixedly connected to one side of the movable frame 24. The first single-head motor 25 provides power for lateral movement.

[0027] A rotating block 29 is rotatably connected inside the mounting bracket 28. A second single-head motor 30 is mounted on the mounting bracket 28 to drive the rotating block 29 to rotate. The second single-head motor 30 provides power for the angle adjustment of the rotating block 29. A hair removal mechanism is connected to the bottom of the rotating block 29. The hair removal mechanism is a component that directly performs the function of shaving hair. The hair removal mechanism includes a mounting block 31 fixedly connected to the bottom of the rotating block 29. A mounting groove 32 is opened on one side of the mounting block 31. A scraper 33 is detachably mounted at the mounting groove 32 by multiple fixing bolts. This detachable design makes it easy to replace or maintain the scraper 33 after it wears out.

[0028] In use, the operator first rotates the flipping block 7 on one side of the top of the fixed frame 3 around the hinge 8 to the open state, forming a loading channel. Then, the slaughtered cattle carcass is placed on the upper surface of the moving plate 40. The third hydraulic cylinder 39 at the bottom of the support frame 1 is activated, its telescopic end rising upwards, pushing the moving plate 40 smoothly upwards through the fixedly connected insert plate 42 until the area to be fixed to the cattle carcass is at a suitable height with the pins 12 of the clamping mechanisms on both sides. Next, the first hydraulic cylinder 6 fixed to the top of the two fixed blocks 5 is activated simultaneously. The telescopic end of the first hydraulic cylinder 6 pushes the telescopic column 9 horizontally towards the center. The telescopic column 9 drives the rotating plate 10 and the mounting plate 11 to move, ultimately causing the pins 12 on the mounting plate 11 to pierce the cattle carcass, completing the reliable fixation of the cattle carcass.

[0029] After fixing, the hair removal operation begins. First, the second hydraulic cylinder 21 at the top of the moving frame 20 is activated, its telescopic end extending downwards to push the connecting block 23 downwards. This, in turn, causes the moving frame 24, fixed to the bottom of the connecting block 23, to descend as a whole until the scraper 33 below the moving frame 24 contacts the surface of the cow's body. To optimize the scraping effect, the second single-head motor 30 on the mounting frame 28 can be activated to drive the rotating block 29 to rotate, thereby adjusting the working angle of the mounting block 31 fixed to the bottom of the rotating block 29 and the scraper 33 on it, so that it better conforms to the curve of the body surface. At the same time, the first single-head motor 25 on one side of the moving frame 24 can be activated to drive the lead screw 37 to rotate, causing the moving block 27 and the mounting frame 28, which are threadedly connected to the lead screw 37, to slide laterally along the guide groove 26, precisely adjusting the lateral position of the scraper 33.

[0030] After preparation, the dual-head motor 18 on the U-shaped frame 13 is started. The dual-head motor 18 drives the two worm gears 35 to rotate synchronously. The worm gears 35 mesh with the worm wheel 36 fixed on the connecting rod 34, transmitting power to the connecting rod 34. The connecting rod 34 drives the two threaded rods 17 to rotate synchronously, driving the movable frame 20, which is threadedly connected to the threaded rods 17, to move along the length of the first slide groove 14, thereby driving the scraper 33 to complete the full scraping of one side of the cow's body.

[0031] After one side of the cow is shaved, the third hydraulic cylinder 39 is retracted, causing the moving plate 40 to descend and separate from the cow's body. At this point, the cow's body is completely suspended in the air, supported by the pins 12 on both sides. The operator can use external force to push the rotating plate 10, causing it to rotate around the end of the telescopic column 9, thereby flipping the cow's body over. After flipping it into place, the third hydraulic cylinder 39 is again controlled to raise the moving plate 40, slightly supporting the cow's body to increase stability. Then, following the above procedure, the scraper 33 can be started to remove hair from the other side of the cow's body.

[0032] During the entire hair-shaving process, the shaved hair falls into the support frame 1 through the collection groove 38 at the bottom of the fixed frame 3, and finally collects in the collection box 4 inserted from the through groove 2 for easy centralized cleaning. After all the work is completed, the clamping mechanism is released, and the processed cow carcass can be removed.

[0033] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
