Technical Field
[0001] This invention relates to the field of livestock slaughtering equipment technology, specifically a rotary slaughtering auxiliary device. Background Technology
[0002] In the process of large-scale livestock slaughtering and processing, slaughtering auxiliary devices are key equipment used to fix the head of the livestock, guide the slaughtering knife to accurately pierce the carotid artery and complete the bleeding operation. Traditional slaughtering auxiliary devices usually include a rotating slaughtering box and a head fixing mechanism set on the rotating slaughtering box. After the operator puts the head of the livestock out of the head protrusion, the slaughtering knife is driven manually or semi-automatically to pierce the neck of the livestock for bleeding. With the improvement of the mechanization of the slaughtering industry, the rotary slaughtering auxiliary device has been widely used because it can realize the continuous operation of multiple livestock and improve slaughtering efficiency.
[0003] However, existing rotary slaughtering auxiliary devices still have the following technical problems in actual use: First, the severe blood splattering during slaughtering causes blood waste and environmental pollution. In existing equipment, when the slaughtering knife pierces the animal's carotid artery, the pressure generated by the rupture of the blood vessel causes blood to splatter violently in all directions. On the one hand, the splattered blood cannot be effectively collected, resulting in a large amount of blood loss and waste, which, according to statistics, causes significant economic losses. On the other hand, the splattered blood contaminates the slaughtering equipment, the ground, and the work clothes of the operators, increasing the workload of subsequent cleaning and disinfection and worsening the sanitary environment of the slaughterhouse.
[0004] Secondly, the lack of effective closed-loop cleaning functions before and after slaughter poses a potential health hazard to meat products. Existing equipment typically lacks the function of cleaning the neck area of livestock before slaughter. During transportation and waiting for slaughter, livestock, especially the neck area, easily accumulates dirt, feces, feed residue, and other contaminants. If not effectively cleaned before slaughter, these contaminants will contaminate the incision and meat tissue along with the blood when the slaughtering knife pierces the meat, affecting the hygiene and safety of the meat. In addition, after slaughter, a large amount of blood and fat tissue remain on the surface of the slaughtering knife. If not cleaned in time, the dried blood will corrode the blade and breed bacteria, affecting the service life of the knife and the hygiene of the next slaughter. Existing equipment lacks an automatic knife cleaning mechanism linked to the slaughtering action, requiring operators to manually disassemble the knives for cleaning, which is inefficient and poses a safety risk.
[0005] Third, the cleaning and slaughtering actions of existing equipment interfere with each other and are difficult to coordinate. Although some existing equipment is equipped with a spray cleaning structure, there is a lack of reasonable linkage control logic between the cleaning action and the slaughtering action. For example, if spraying is carried out at the same time during the slaughtering process, the water flow will mix with the splashed blood, aggravating the degree of blood splashing and causing more serious pollution. If the cleaning cannot be effectively sealed, the cleaning water will carry blood everywhere, increasing the difficulty of sewage treatment. Existing technology has failed to solve the coordination problem between the two processes of cleaning and slaughtering, resulting in poor cleaning effect or obstruction of slaughtering operation.
[0006] To address the aforementioned issues, there is an urgent need to develop a new type of rotary slaughtering auxiliary device capable of achieving closed slaughtering, pre-slaughter closed cleaning of livestock necks, and post-slaughter closed cleaning of the slaughtering knife, in order to solve technical problems such as blood waste, meat contamination, and poor process coordination. Summary of the Invention
[0007] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a rotary slaughtering auxiliary device.
[0008] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a rotary slaughtering auxiliary device, comprising a rotary slaughtering box, wherein the interior of the rotary slaughtering box is provided with a head extension opening, and a head and neck fixing mechanism located at the head extension opening is installed on the rotary slaughtering box; The head and neck fixing mechanism includes a limiting frame fixed to the side of the rotating slaughter box. A spray box is installed inside the limiting frame. An inner inclined box is fixedly installed at the upper end of the spray box. An arc box is fixedly installed at the top of the inner inclined box. An outer inclined box corresponding to the inclined surface of the inner inclined box is movably sleeved inside the lower end of the limiting frame. A slaughter knife mechanism that can swing left and right is elastically connected inside the outer inclined box. A pneumatic cylinder is fixedly installed at the lower end of the limiting frame. The upper end of the pneumatic cylinder is fixedly connected to the slaughter knife mechanism. The head and neck fixing mechanism has a slaughtering station and a cleaning station: at the slaughtering station, the pneumatic cylinder drives the slaughtering knife mechanism to move upward and extend out of the outer inclined box, while simultaneously moving the outer inclined box upward until it contacts the inclined surface of the inner inclined box, thereby blocking or changing the water spray path of the spray box and preventing water from spraying onto the slaughtering area during the slaughtering process, thus preventing blood contamination; at the cleaning station, the pneumatic cylinder drives the slaughtering knife mechanism to retract downward, while simultaneously moving the outer inclined box downward and separating it from the inclined surface of the inner inclined box, thus ensuring unobstructed water spray path of the spray box for spray cleaning of the slaughtering knife mechanism.
[0009] Preferably, the limiting frame includes a mounting frame, with fixed frames fixedly mounted at its left and right ends respectively. Bolts are installed inside the fixed frames to fix the fixed frames to the rotating slaughter box. A sliding groove is opened inside the mounting frame, and a slider is movably sleeved inside the sliding groove. The other end of the slider is fixedly connected to the spray box.
[0010] Preferably, the spray box includes a sleeve box fixed to the bottom of the inner inclined box. The sleeve box has a cavity inside, and the sleeve box has annular equidistant inclined spray holes and straight spray holes. The inclined spray holes can spray towards the neck of the slaughtered livestock for cleaning, and the straight spray holes can spray towards the slaughtering knife mechanism for cleaning.
[0011] Preferably, a first threaded sleeve is fixedly installed inside the casing, the first threaded sleeve is in communication with the cavity, and a second connecting hose is threadedly connected to the other end of the first threaded sleeve. The other end of the second connecting hose is pumped to the water storage device by a water pump.
[0012] Preferably, a second threaded sleeve is provided at the lower end of the casing, one end of the second threaded sleeve is connected to the inner cavity of the casing, and the other end of the second threaded sleeve is threadedly connected to a first connecting hose, the other end of the first connecting hose is connected to an external drainage device.
[0013] Preferably, the outer inclined box includes a box body that is movably fitted inside the limiting frame. A base plate is fixedly installed inside the lower end of the box body, and rigid springs are fixedly installed around the top of the base plate. The upper end of the rigid springs is fixedly connected to the slaughtering knife mechanism.
[0014] Preferably, the slaughtering knife mechanism includes a convex block and an arc-shaped guide groove opened inside the lower end of the box. The convex block is movably sleeved inside the upper end of the box. The bottom of the convex block is fixedly connected to the upper end of the air cylinder and the rigid spring. A circular shaft disk is rotatably sleeved inside the convex block. A slaughtering knife is fixedly installed on the upper end of the circular shaft disk. A rotating block is fixedly connected to the lower end of the slaughtering knife. An insert rod is movably sleeved inside the lower end of the rotating block. The front and rear ends of the insert rod are respectively slidably fitted in the arc-shaped guide groove. When the convex block moves up and down, the insert rod moves along the arc-shaped guide groove, forcing the rotating block and the butcher knife to deflect, thereby achieving left and right swinging.
[0015] Preferably, a movable box is movably fitted inside the upper end of the box body. The upper end of the movable box is fixed to the bottom of the convex block. When the convex block moves upward, the movable box slides upward along the inner wall of the box body to prevent livestock blood at the top of the box body from being discharged from the gap between the convex block and the box body.
[0016] Preferably, a third threaded sleeve is fixedly installed inside the upper end of the box body. The upper end of the third threaded sleeve contacts the bottom of the convex block, and a third connecting hose is threaded onto the lower end of the third threaded sleeve. The other end of the third connecting hose is connected to an external blood storage device.
[0017] Preferably, a rubber sleeve is fixedly installed on the top of the arc-shaped box, and the outer surface of the rubber sleeve is waterproof and soft.
[0018] (III) Beneficial Effects Compared with the prior art, the present invention provides a rotary slaughtering auxiliary device, which has the following beneficial effects: 1. By setting up an inner inclined box and an outer inclined box that cooperate with each other, when the slaughtering station is in operation, the pneumatic cylinder drives the outer inclined box to move upward and contact the inclined surface of the inner inclined box to form a closed structure. This restricts the piercing action of the slaughtering knife mechanism within the closed space. This structure effectively prevents blood from splashing around due to the rupture of blood vessels in the neck of livestock during slaughter, allowing the blood to flow downward in a concentrated manner and be smoothly collected to the external blood storage equipment through the third threaded sleeve and the third connecting hose. This avoids the waste of blood and significantly improves the blood collection rate and the economic benefits of the slaughterhouse.
[0019] 2. After the slaughtering process is completed and the slaughtering knife mechanism retracts downwards, the head and neck fixing mechanism automatically switches to the cleaning station. At this time, the outer inclined box and the inner inclined box are separated, and the water spray path of the spray box is unobstructed. The retracted slaughtering knife mechanism is sprayed and cleaned through straight spray holes. This cleaning process is completed in a closed structure. The wastewater after cleaning is discharged in a concentrated manner through the first connecting hose. This not only achieves timely cleaning of the knife after slaughtering, but also avoids the splashing of cleaning water and residual blood to pollute the working environment, realizing the integrated linkage of cleaning and sealing.
[0020] 3. Before the slaughtering operation begins, the head and neck fixing mechanism is in the cleaning position. The outer inclined box and the inner inclined box are separated. The spray box sprays high pressure onto the slaughtering area of the animal's neck through inclined nozzles to remove dirt, hair and microorganisms attached to the skin. After cleaning, the device is switched to the slaughtering position. The outer inclined box moves upward and closes with the inner inclined box. Slaughter is carried out in a clean and closed environment. This design effectively avoids the contamination of meat products by the mixing of dirt on the animal's body surface and blood during the slaughtering process, ensuring slaughter hygiene and the safety of the final meat products for consumption from the source.

[0023] In this invention, unless otherwise stated, the directional terms such as "up" and "down" generally refer to the directions shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.
[0024] Example 1: Enclosed slaughtering to avoid blood splashing and waste. This embodiment focuses on how to achieve closed slaughtering through the closed structure of the inner and outer inclined boxes, thereby avoiding blood splashing and waste and improving blood collection rate.
[0025] In one specific implementation, according to Figures 1-10 As shown, a rotary slaughtering auxiliary device has a head and neck fixing mechanism 3 configured to form a closed space at the slaughtering station. Specifically, a restraining frame 31 is fixedly installed on the side of the rotary slaughtering box 1. An outer inclined box 36 is movably sleeved inside the restraining frame 31. An inner inclined box 33 is fixed to the upper end of the spray box 32 above the outer inclined box 36. The inclined surface of the inner inclined box 33 matches the inclined surface of the outer inclined box 36 in shape and angle. Both are conical inclined surface structures that slope outward from top to bottom.
[0026] When slaughtering operations are required, the control system sends an extension command to the pneumatic cylinder 38. The piston rod of the pneumatic cylinder 38 extends upward, driving the slaughtering knife mechanism 37 to move upward as a whole. During the upward movement, the slaughtering knife mechanism 37 first drives the convex block 371 inside to slide along the inside of the upper end of the box 361. The upper end face of the convex block 371 then contacts the bottom of the outer inclined box 36 and pushes the outer inclined box 36 to move upward together. As the pneumatic cylinder 38 continues to extend, the inclined surface of the outer inclined box 36 gradually approaches and finally fits tightly with the inclined surface of the inner inclined box 33, forming a ring-shaped closed seam. This closed seam completely encloses the slaughtering knife 373 of the slaughtering knife mechanism 37 in a relatively sealed cavity. At the same time, the insertion rod 375 slides along the arc-shaped guide groove 376, forcing the rotating block 374 and the butcher knife 373 to deflect. The butcher knife 373 extends upward from the top opening of the outer inclined box 36 in a left-right swinging manner and pierces the animal's carotid artery. Since the outer inclined box 36 and the inner inclined box 33 are in a closed state, the water spray paths of the straight spray hole 324 and the inclined spray hole 323 of the spray box 32 are effectively blocked by the side wall of the outer inclined box 36. At this time, no high-pressure water is sprayed out, avoiding the mixing of water with splashed blood. After the animal's carotid artery is punctured, blood gushes out under the pump pressure of the heart. Since the stabbing action of the butcher knife 373 and the gushing of blood both occur within the enclosed space formed by the inner inclined box 33 and the outer inclined box 36, the blood cannot splash in all directions. Instead, it flows downward along the opening at the top of the box 361 and the inclined surface of the inner inclined box 33. A third threaded sleeve 364 is fixedly installed inside the upper part of the box 361. The upper end of the third threaded sleeve 364 contacts the bottom of the convex block 371. The flowing blood enters the third threaded sleeve 364 under the action of gravity, and is then smoothly transported to the blood storage device outside through the third connecting hose 365 threaded to the lower end of the third threaded sleeve 364.
[0027] This embodiment achieves the following technical effects through the closed design of the inner and outer inclined boxes at the slaughtering station: First, the closed structure effectively intercepts blood splashing outwards, improving the blood collection rate compared to the shortcomings of traditional open slaughtering; Second, it avoids the contamination of the slaughterhouse floor, equipment, and operators by blood splashing, improving the hygiene of the working environment; Third, the collected blood has a low impurity content, which is beneficial for subsequent deep processing and utilization of blood, significantly improving the economic benefits of the slaughterhouse.
[0028] Example 2: Post-slaughter integrated cleaning of butcher knives This embodiment focuses on the process where, after slaughtering, the device automatically switches to the cleaning station and sprays the butcher knife for cleaning in a closed state, achieving integrated cleaning and sealing.
[0029] In one specific embodiment, after the above-mentioned rotary slaughtering auxiliary device completes the slaughtering operation, it automatically enters the slaughtering knife cleaning program. When it is detected that the animal's blood has been basically drained and the slaughtering operation is over, the control system sends a contraction command to the pneumatic cylinder 38. The piston rod of the pneumatic cylinder 38 retracts downward, causing the convex block 371 to move downward against the elastic force of the rigid spring 363. During the downward movement of the convex block 371, it first causes the moving box 366 to slide downward along the inner wall of the box 361. The upper end of the moving box 366 always remains fixedly connected to the bottom of the convex block 371, thereby effectively sealing the gap between the convex block 371 and the box 361 and preventing sewage from seeping out from the gap during the subsequent cleaning process. At the same time, the insertion rod 375 slides in the opposite direction along the arc-shaped guide groove 376, forcing the rotating block 374 and the butcher knife 373 to deflect and reset in the opposite direction. The butcher knife 373 retracts downward into the interior of the outer inclined box 36 in a left-right swing manner. After the butcher knife 373 is completely retracted into the interior of the outer inclined box 36, the convex block 371 continues to move downward, and its bottom connects with the upper end of the rigid spring 363. The rigid spring 363 is further compressed to store elastic potential energy. The upper end face of the convex block 371 disengages from the bottom of the outer inclined box 36. Under the combined action of its own weight and the downward pulling force transmitted by the rigid spring 363 through the convex block 371, the outer inclined box 36 moves downward as a whole, so that the inclined surface of the outer inclined box 36 gradually separates from the inclined surface of the inner inclined box 33, and the device switches to the cleaning station. After the outer inclined box 36 and the inner inclined box 33 are separated, the water spray path of the spray box 32 is restored to unobstructed. At this time, the water pump is started, and the cleaning water in the water storage device is pumped into the first threaded sleeve 325 through the second connecting hose 328. After the cleaning water enters the cavity 322 of the sleeve 321, part of it is sprayed horizontally or obliquely downward through the annularly distributed straight spray holes 324, directly spraying onto the surface of the butcher knife 373 retracted inside the outer inclined box 36, and high-pressure washing of the blood residue, fat tissue and other pollutants attached to the butcher knife 373. Since the butcher knife 373 is completely retracted inside the outer inclined box 36; The wastewater after cleaning flows downward under the action of gravity, enters the first connecting hose 327 through the second threaded sleeve 326, and is finally transported to the external drainage equipment for centralized treatment. After the cleaning operation continues for a preset time, the water pump is turned off, the cleaning program ends, and the device is in standby mode, waiting for the next slaughtering operation. This embodiment achieves the following technical effects through the design of a post-slaughter knife cleaning linkage: First, the cleaning is completed automatically without manual disassembly of the knife after slaughter, improving work efficiency; Second, the cleaning process is carried out in a semi-enclosed space, reducing splashing of blood and cleaning water mixtures and environmental pollution; Third, the cleaning and sealing actions are linked by the same pneumatic cylinder 38, requiring no additional power source or control logic, resulting in a compact structure and high reliability; Fourth, the wastewater after cleaning is centrally collected and treated, meeting the environmental protection discharge requirements of the slaughtering industry.
[0030] Example 3: Before slaughter, the animal's neck area should be sealed and cleaned to prevent blood contamination. This embodiment focuses on describing the specific implementation of sealing and cleaning the slaughter area of livestock necks before the slaughtering operation begins. By cleaning the slaughter area in advance, meat contamination can be avoided by mixing surface dirt with blood during the slaughtering process.
[0031] In one specific embodiment, before starting the slaughtering operation, the above-mentioned rotary slaughtering auxiliary device first performs a pre-slaughter cleaning procedure. At this time, the device is in the cleaning position, the pneumatic cylinder 38 is in the retracted state, and the outer inclined box 36 and the inner inclined box 33 are in the inclined separation state. The operator puts the head of the animal to be slaughtered through the head opening 2 of the rotary slaughtering box 1, so that the neck of the animal is located inside the arc box 34. A rubber sleeve 35 is fixedly installed on the top of the arc box 34. The outer surface of the rubber sleeve 35 is waterproof and soft. When the neck of the animal enters the arc box 34, the rubber sleeve 35 makes elastic contact with the animal's skin to form a flexible seal, preventing water from overflowing from the top during the cleaning process, and also avoiding scratching the animal's skin and causing stress reaction in the animal. After the cleaning program is started, the water pump starts working, pumping the cleaning water in the water storage device into the cavity 322 of the casing 321 of the spray box 32 through the second connecting hose 328. After the cleaning water is evenly distributed in the cavity 322, it is sprayed upward through the annular equidistant inclined spray holes 323 opened inside the casing 321. The spray direction of the inclined spray holes 323 is precisely designed, and its spray angle matches the inclined angle of the inner inclined box 33, so that the sprayed high-pressure water flow can fully cover the area of the animal's neck that is about to be slaughtered, including the jugular vein groove, throat and the skin folds on both sides. High-pressure water jets continuously spray and clean the slaughter area of the animal's neck, removing dirt, feces, residual feed, hair, and surface microorganisms. During the cleaning process, due to the flexible seal between the rubber sleeve 35 and the animal's skin, the cleaning water does not overflow from the top in large quantities, but flows down along the contour of the animal's neck, collecting at the bottom of the spray box 32 through the inner walls of the arc box 34 and the inner inclined box 33. The collected wastewater enters the first connecting hose 327 through the second threaded sleeve 326 and is transported to the external drainage equipment. The cleaning operation continues for a preset time to ensure that the cleanliness of the slaughter area meets the hygiene standards. After the cleaning process is completed, the water pump is turned off and the spraying stops. Then, the device automatically switches to the slaughtering station: the pneumatic cylinder 38 extends upward, driving the slaughtering knife mechanism 37 to move upward, and at the same time driving the outer inclined box 36 to move upward until it contacts the inclined surface of the inner inclined box 33 to form a seal. At this time, the slaughtering knife 373 pierces the neck of the pre-cleaned livestock in the closed environment. Since the slaughtering area has been thoroughly cleaned before slaughter, when the slaughtering knife 373 pierces the blood vessel and causes blood to spray out, the sprayed blood will not mix with the original dirt on the surface of the livestock, such as mud and feces, thus ensuring that the flowing blood has a high purity and avoiding dirt from contaminating the meat tissue around the slaughtering incision along with the blood. This embodiment achieves the following technical effects through a pre-slaughter closed cleaning design of the animal's neck area: First, targeted high-pressure spray cleaning of the target area before slaughter effectively removes dirt and microorganisms attached to the skin, ensuring meat hygiene and safety from the source; Second, the flexible sealing design of the rubber sleeve 35 prevents cleaning water from overflowing and avoids animal stress, balancing cleaning effectiveness and animal welfare; Third, pre-slaughter cleaning and slaughtering are completed sequentially at the same workstation, eliminating the need to move the animals and reducing operational steps and animal stress; Fourth, the cleanliness of the slaughter area is significantly improved after cleaning, resulting in lower impurity content in the collected blood, which is beneficial for the deep processing and utilization of blood products; Fifth, it avoids the problem of surface dirt contaminating meat with blood during traditional slaughtering, improving the final meat quality grade and market value.
[0032] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
