Description

Technical Field

[0001] This application relates to the field of food processing machinery, and more specifically, to a device for removing oil from the V-bone of broiler chickens. Background Technology

[0002] In the deep processing of broiler chickens, chicken breast meat is a core raw material for making high-value-added products such as chicken cutlets and chicken strips, making its quality control crucial. The V-bone region, where the inner side of the breast connects to the clavicle (V-bone), has a unique structure composed of irregularly distributed subcutaneous fat, dense connective tissue, and cartilage fragments. The fat layer and muscle tissue are tightly interwoven and of uneven thickness, significantly increasing the difficulty of trimming. Traditional processes rely entirely on manual operation, requiring workers to use hand-held knives for precise scraping on high-speed production lines. However, this method faces multiple challenges: the operation is highly dependent on personal experience and immediate condition; the training period for skilled workers is long and the turnover rate is high, causing frequent production line interruptions; in continuous operation, ergonomic limitations make workers prone to fatigue, leading to distorted degreasing movements. Sometimes residual fat affects the product's taste and shelf life, while sometimes excessive cutting damages muscle fibers, directly reducing the proportion of edible portion; simultaneously, the open operating environment exposes the chicken breast meat repeatedly to human contact, significantly increasing the risk of contamination by pathogens such as Salmonella, and knife slippage or misoperation can easily cause cuts. These defects not only drive up unit production costs, but also lead to large fluctuations in product quality and limited market competitiveness, seriously hindering the automation upgrade and large-scale development of the poultry processing industry. Summary of the Invention

[0003] To overcome the above problems, the purpose of this invention is to provide a broiler V-bone degreasing device that can automatically remove fat from the V-bone area, reduce reliance on manual experience, reduce quality fluctuations caused by worker fatigue, and improve production efficiency and product consistency.

[0008] Furthermore, the monitoring camera scans the chicken breast, and the intelligent control system identifies the precise three-dimensional coordinates, contour, and fat thickness distribution of the V-bone area. Based on the three-dimensional model of the V-bone area, the control system generates a contour-following degreasing path. The degreasing mechanism drives a high-speed rotating flexible brush to perform multiple contour-following scrapes along the planned path at an angle of 10-45 degrees to the meat surface.

[0009] Furthermore, the oil scraping mechanism includes an arc-shaped brush blade. Guide rails are provided at both ends of the upper surface of the extended base plate.

[0012] Furthermore, it also includes a control system, which is pre-installed with a V-bone region recognition and path planning algorithm based on machine learning training. Its workflow is as follows: receiving three-dimensional point cloud data → identifying and locating the V-bone region boundary and fat thickness distribution → planning the optimal degreasing path (contour path) → coordinating the control of the oil scraping mechanism to drive the brush blade to move along the planned path at a specific angle, pressure, and speed, while controlling the clamping unit to make adaptive fine adjustments → performing closed-loop control based on visual feedback to ensure thorough degreasing without damaging the meat.

Detailed Implementation

[0022] The invention will now be further described with reference to the accompanying drawings.

[0023] Please see Figures 1 to 7As shown, a degreasing device for V-bones of broiler chickens according to the present invention includes a support base 1. Support rods 11 are provided around the upper surface of the support base 1. A fixed seat 2 is mounted on the support rods 11. A first annular guide groove 21 is provided on the lower surface of the fixed seat 2. A plurality of placement pieces 3 for placing broiler V-bones are arranged at equal intervals in the first annular guide groove 21. A driving member 4 for driving the placement pieces 3 to rotate is provided on the fixed seat 2. A discharge conveyor belt 5 for discharging degreased broiler V-bones is provided at the front end of the upper surface of the support base 1. An extension base plate 6 extends outward from the middle of the upper part of the rear surface of the support base 1. An oil scraping mechanism 7 for degreasing broiler V-bones is provided on the upper surface of the extension base plate 6.

[0024] For ease of understanding, the following explains some key terms in this embodiment: Support base: As the basic structure of the entire white-feathered broiler V-bone degreasing device, its main function is to provide a stable support platform, support the various components of the device, and ensure the stability of the equipment during operation.

[0025] Support rods: These are installed around the upper surface of the support base to extend upwards and support the fixed base, thereby constructing the overall frame structure of the device.

[0026] Fixed base: mounted on the support rod, it is one of the core load-bearing components of the device. Its lower surface has guide rail grooves and supports key components such as drive components.

[0027] First annular guide groove: It is formed on the lower surface of the fixed base to form an annular path, which is used to guide the placed part to move cyclically along a predetermined trajectory.

[0028] Placement components: These are evenly spaced within the first annular guide rail groove and are specifically designed to stably support the V-bones of the broiler to be degreased, and move along with the guide rail groove.

[0029] Drive unit: Located on the fixed base, its function is to provide power to drive the placement unit to rotate along the first annular guide groove, so as to realize the continuous conveying of the V-bone.

[0030] Discharge conveyor belt: Located at the front end of the upper surface of the support base, it is used to receive the degreased chicken V-bone and transport it to the next processing stage or collection area.

[0031] Extended base plate: Extends outward from the middle of the upper part of the rear surface of the support base to provide an installation platform and operating space for the oil scraping mechanism.

[0032] Oil scraping mechanism: Located on the upper surface of the extension base plate, it is the core functional component for removing oil from the V bone of broilers. It removes fat and connective tissue from the V bone area through mechanical action.

[0033] This embodiment provides a degreasing device for V-bone of white-feathered broiler chickens, the main technical features of which are described in detail below: The device includes a support base, which can be constructed from various materials, such as welded steel structures for high strength and stability, or modular aluminum alloy frames for lightweighting and ease of assembly. The size and shape of the support base can be customized to suit the spatial layout and load-bearing requirements of the actual production line.

[0034] Support rods are installed around the upper surface of the support base. These support rods can be solid cylindrical steel rods, fixed to the support base by bolting or welding to provide robust vertical support. Alternatively, the support rods can be height-adjustable telescopic rods to facilitate adjustment of the working height of the fixed base.

[0035] A mounting base is provided at the upper end of the support rod. This mounting base can be a single cast metal structure, connected to the support rod via a flange or pin connection to ensure its stability. In other embodiments, the mounting base can also be assembled from multiple plates using bolts for easy maintenance and component replacement.

[0036] A first annular guide groove is formed on the lower surface of the fixed base. This guide groove can be directly machined into the fixed base body using a precision milling process, and its cross-sectional shape can be U-shaped to accommodate and guide the slider. As an alternative, the guide groove can also be composed of independent annular guide rail segments spliced ​​together and fixed to the lower surface of the fixed base with screws.

[0037] Within the first annular guide rail groove, multiple supports for arranging the V-bones of broilers are arranged at equal intervals. These supports can be simple metal hook structures, directly suspended from pulleys within the guide rail groove to support the V-bones. In another implementation, the supports can be designed as trays with clamping functions, using springs or gravity to initially fix the V-bones.

[0038] The mounting base is equipped with a drive mechanism for rotating the placed component. This drive mechanism can be a manual crank mechanism, whereby an operator rotates the crank to move the placed component. As a more automated implementation, the drive mechanism can also be a pneumatic motor, which uses air pressure to drive gears or chains, thereby causing the placed component to rotate continuously or intermittently along the annular guide groove.

[0039] At the front end of the upper surface of the support base, a discharge conveyor belt for the degreased chicken V-bone is installed. This conveyor belt can be a simple flat belt conveyor driven by a small motor, smoothly conveying the processed V-bone. In other embodiments, a roller conveyor line can also be used to guide the V-bone to a collection container by gravity or friction.

[0040] An extension base plate extends outward from the center of the upper part of the rear surface of the support base. This extension base plate can be a steel plate fixedly welded to the support base, providing a stable plane. As an adjustable implementation, the extension base plate can also be designed as a telescopic structure, with its extension length adjusted via a manual locking mechanism to accommodate oil scraping mechanisms of different sizes.

[0041] On the upper surface of this extended base plate, an oil-scraping mechanism is provided for removing oil from the V-bone of the broiler. This mechanism can be a simple fixed scraper, where oil is scraped away through the relative movement of the V-bone and the scraper. Alternatively, the oil-scraping mechanism can be a device with a rotating brush head driven by a small motor, which removes grease through contact between the bristles and the surface of the V-bone.

[0042] The following example will provide a more detailed explanation of the above technical solution: Suppose a broiler chicken processing plant at location A needs to automate the degreasing process of the V-bone area on a large quantity of chicken breast meat to solve the problems of low efficiency and inconsistent quality associated with traditional manual degreasing. The plant has implemented the broiler chicken V-bone degreasing device described in this embodiment.

[0043] First, the V-bones of broiler chickens to be processed are placed onto the placement pieces of the device manually or via pre-processing equipment. These placement pieces are evenly distributed within the first annular guide groove on the lower surface of the mounting base. Each placement piece is designed to stably support one V-bone.

[0044] Subsequently, the drive unit mounted on the fixed base is activated. This drive unit, through its internal mechanism, such as a gear or chain system, begins to drive the placement component within the first annular guide groove to rotate uniformly or intermittently along the annular path. Thus, the V-ribs erected on the placement component are continuously conveyed.

[0045] As the V-bone rotates with the placement device to the rear region, it directly aligns with the oil-scraping mechanism located on the upper surface of the extension base plate. The oil-scraping mechanism is activated and begins to remove oil from the V-bone area it passes through. For example, the oil-scraping mechanism could be a device with a rotating brush head that contacts the V-bone surface at a preset speed and angle, scraping away attached subcutaneous fat, connective tissue, and cartilage.

[0046] After the oil-scraping mechanism completes the degreasing process, the V-bone continues to rotate with the placement component. When the V-bone rotates to the discharge area at the front end of the upper surface of the support base, the degreased V-bone is automatically or semi-automatically unloaded from the placement component and falls onto the discharge conveyor belt located in that area. The discharge conveyor belt then starts, transporting the degreased V-bone to subsequent cleaning, packaging, or other processing stages.

[0047] Throughout the process, the support base provides a solid foundation for the device, ensuring its stability during long-term operation. The support rod firmly supports the fixed base, allowing the placement and driving components to operate precisely on a stable plane. The extended base plate provides the necessary installation space and working platform for the oil scraping mechanism. Through this collaborative working method, the device achieves automated and continuous oil removal from the V-bone of broiler chickens.

[0048] Based on the above examples, the degreasing device for V-bone of broiler chickens in this embodiment demonstrates significant technical contributions.

[0049] Compared to the traditional manual degreasing method mentioned in the background section, this device achieves continuous and batch processing of V-bones by introducing automated drive components and annular guide rail grooves. In the processing plant example at location A, the V-bones do not need to be manually trimmed one by one. Instead, they are automatically sent to the degreasing mechanism for processing through the cyclic rotation of the placement parts. This directly solves the problems of low efficiency and high labor costs of traditional manual operation.

[0050] Furthermore, this device ensures consistency and standardization in the degreasing process through the mechanized operation of the scraping mechanism. In manual degreasing, the effectiveness is affected by the operator's skill and fatigue, easily leading to incomplete fat removal or over-scraping of muscle. However, the scraping mechanism of this device, once its operating parameters are set, can process each V-bone segment in a stable manner, effectively improving the stability of degreasing quality and reducing the risk of compromised product yield.

[0051] Furthermore, the automated design of this device significantly reduces hygiene and safety risks during production. In manual operation, the use of knives and direct contact between hands and meat increases the possibility of microbial contamination and also poses a risk of workplace injuries. This device automates the V-bone conveying and degreasing processes, reducing direct contact between hands and meat, helping to maintain higher hygiene standards, and avoiding the safety hazards associated with knife operation.

[0052] In summary, the broiler V-bone degreasing device of this embodiment provides an efficient, stable, and hygienic solution through its integrated design and automated processing flow. It effectively overcomes many drawbacks of manual degreasing in the prior art and brings substantial technological progress to the broiler deep processing industry.

[0053] In some of the embodiments described above in this application, a driving member for driving the placement member to rotate is proposed. However, in practical applications, how to ensure that the placement member achieves stable, continuous and high-precision synchronous rotation within the first annular guide groove to meet the process requirements of degreasing the V-bone of broilers is a technical problem that needs to be solved.

[0054] Please continue reading. Figures 1 to 3 , Figure 6 and Figure 7 As shown, this application further proposes that the aforementioned driving component 4 includes a first motor 41. The first motor 41 is disposed in the middle of the upper surface of the fixed base 2. The output end of the first motor 41 is connected to a rotating shaft 42. The rotating shaft 42 is disposed within the fixed base 2, and a driving gear 43 is disposed on the rotating shaft 42. A driving gear 44 and a driven gear (not shown) are respectively disposed at the left and right ends of the fixed base 2. The driving gear 44 and the driven gear are connected by a chain 45. The driving gear 43 and the driving gear 44 are connected by a toothed belt 46. The chain 45 is disposed within the first annular guide groove 21. This first motor is the core component providing mechanical power, and its function is to convert electrical energy into mechanical energy to drive the entire transmission system. The first motor can be of various types. For example, to achieve precise speed and position control, a servo motor or a stepper motor can be selected; if only continuous and stable rotation is required, an AC asynchronous motor or a DC motor can be selected. In some embodiments, the first motor can be mounted in the middle of the upper surface of the fixed base. This layout is beneficial for structural compactness and power transmission stability, and can effectively reduce energy loss in the transmission path. The output end of the first motor is connected to a rotating shaft, which serves as the medium for power transmission, transmitting the rotational motion of the first motor to the subsequent transmission mechanism. The rotating shaft is typically housed within the fixed base and positioned and supported by bearings and other supporting components to ensure smooth rotation and withstand working loads. A drive gear is mounted on the rotating shaft, which is the starting point of the entire transmission chain and is responsible for transmitting the rotational power of the shaft to the toothed belt. The drive gear can be in the form of a synchronous pulley or sprocket, and its design must match the selected transmission belt or chain. A driving gear and a driven gear are respectively located at the left and right ends of the fixed base. These two gears together constitute an important part of the chain drive system. The driving gear receives power from the driving gear, and the driven gear is connected to the driving gear via a chain, forming a closed transmission loop. The driving gear and driven gear are connected by a chain. Chain drives offer advantages such as accurate transmission ratio, high load capacity, and high transmission efficiency, making them particularly suitable for applications requiring synchronous motion and long-distance transmission. The type of chain can be selected based on specific application requirements, such as roller chains, bushing chains, or toothed chains. The drive gear and driving gear are connected by a toothed belt. Toothed belt drives feature smooth transmission, low noise, no lubrication required, and accurate transmission ratio, effectively preventing slippage and ensuring precise power transmission. The toothed belt is typically a synchronous belt, achieving synchronous transmission through meshing with the teeth on the gears. The chain is positioned within the first annular guide groove. This arrangement allows the chain to directly or indirectly mesh with corresponding structures (such as connecting blocks) on the placed component, thereby driving the placed component to perform continuous circular motion along the first annular guide groove.

[0055] The proposed solution uses a first motor as a power source, whose rotational power is first transmitted to a drive gear via a shaft. The drive gear then precisely transmits the power to a driving gear via a toothed belt. The driving gear and the driven gear are connected by a chain, forming a circular chain drive system. This chain is cleverly positioned inside a first circular guide groove, connecting to multiple placement components. When the first motor starts, the entire transmission chain continuously moves within the first circular guide groove, thereby driving all placement components connected to the chain to rotate synchronously and stably along the circular guide groove. This multi-stage transmission design, especially the combination of toothed belts and chains, effectively ensures the smoothness and precision of power transmission, avoiding slippage or asynchrony problems that may occur with traditional single-transmission methods. In this way, the placement components can precisely transport the chicken V-bone to the oil-scraping mechanism at a preset speed and trajectory, ensuring the continuity and consistency of the oil removal process, thereby significantly improving the overall efficiency and oil removal effect of the device.

[0056] The following is a specific example. The first motor can be an AC servo motor with a rated power of 0.75kW, whose output shaft is connected to the rotating shaft via a flexible coupling. The rotating shaft can be a 20mm diameter 45# steel shaft, supported inside the fixed base by two 6204 deep groove ball bearings. The drive gear on the rotating shaft can be a synchronous pulley with a module of 2 and 20 teeth. The driving gear and driven gear at the left and right ends of the fixed base can be sprockets with a module of 3 and 30 teeth. The drive gear and the driving gear are connected by a synchronous belt of model HTD-5M. The driving gear and the driven gear are connected by a roller chain of model 08B. This roller chain is precisely arranged in the first annular guide groove and meshes with the connecting structure on the placement component (e.g., the first connecting block mentioned in later embodiments), thereby realizing the driving of the placement component.

[0057] The above technical solution, employing a combination of a first motor, toothed belt, and chain transmission, provides stable, continuous, and highly precise synchronous rotational power for the placement components. This precise transmission mechanism effectively solves the problem of uneven or asynchronous movement of the placement components within the annular guide groove, ensuring the positioning accuracy and smooth conveying of the broiler V-bone during the degreasing process. This not only improves the automation level and processing efficiency of the degreasing device but also guarantees the consistency and reliability of the degreasing effect, thereby significantly enhancing the overall process performance of degreasing broiler V-bone.

[0058] In some embodiments, this application proposes a degreasing device for broiler V-bones, which includes a placement member for supporting the broiler V-bones and is driven to rotate by a drive member for degreasing. However, in actual operation, how to ensure that the broiler V-bones are stably confined during the degreasing process, and how to achieve efficient and automated discharge after degreasing, are technical problems that need to be further solved.

[0059] Please continue reading. Figures 1 to 3 , Figure 5 As shown, this application further proposes that the placement component 3 of the above-mentioned device includes a U-shaped support slider 31 for limiting the V-bone of the broiler chicken. The lower surface of the fixing base 2 has second annular guide grooves 32 at both the front and rear ends, and the second annular guide grooves 32 are located at the front and rear ends of the first annular guide groove 21. A first connecting block 33 is provided in the middle of the upper horizontal plate of the U-shaped support slider 31, and the first connecting block 33 is embedded in the first annular guide groove 21. The first connecting block 33 is connected to the chain 45. The upper surface of the support slider 31 is provided with a second connecting block 34 at both the front and rear ends. The second connecting block 34 is embedded in the second annular guide groove 32. The lower surface of the U-shaped support slider 31 is provided with a first telescopic cylinder 35 at the rear end. The telescopic rod of the first telescopic cylinder 35 is provided with an air blowing block 36. Multiple high-pressure air blowing heads 37 are provided on the air blowing block 36 with the center of the air blowing block 36 as the center. The middle of the air blowing block 36 is provided with a support rod 38 for supporting the V bone of the broiler.

[0060] The U-shaped support slider is a component with a U-shaped structure that supports and limits the V-bone of the broiler chicken. Its function is to provide stable support and prevent the V-bone from shifting or falling off during the degreasing process. This U-shaped support slider can be integrally molded from high-strength, wear-resistant engineering plastics (such as polyoxymethylene or ultra-high molecular weight polyethylene) to ensure its structural strength and protection of the broiler V-bone; or it can be composed of a metal frame (such as stainless steel) combined with food-grade rubber or silicone pads to balance strength and flexible contact with the broiler V-bone. The second annular guide groove is an annular groove opened on the lower surface of the fixed base, arranged parallel or concentrically with the first annular guide groove. Its function is to provide additional guidance and support for the U-shaped support slider, enhancing its operational stability and smoothness. This second annular guide groove can be integrally formed directly on the lower surface of the fixed base by milling or casting to ensure its structural integrity with the fixed base; alternatively, it can be fixed by embedding an independent annular guide rail (such as U-shaped steel or aluminum alloy profile) into a pre-reserved groove in the fixed base for easy replacement or maintenance. The first connecting block is located in the middle of the upper surface of the U-shaped support slider's horizontal plate and is used to connect with the drive chain. Its function is to act as a mechanical interface between the U-shaped support slider and the drive chain, transmitting power from the drive component to the U-shaped support slider, causing it to move along the first annular guide groove. This first connecting block can be a metal block with pin holes or slots, fixed to the U-shaped support slider by bolts or riveting and connected to a link of the chain; alternatively, it can be a protrusion pre-installed on the U-shaped support slider body, directly engaging or locking with a specific part of the chain. The second connecting blocks are located at the front and rear ends of the upper surface of the U-shaped support slider's horizontal plate and are used to embed into the second annular guide groove. Their function is to provide additional guidance and support when the U-shaped support slider moves along the first annular guide groove, preventing the U-shaped support slider from swaying or tilting. The second connecting block can be a pair of sliders or rollers that match the shape of the second annular guide groove, connected to the U-shaped support slider via bearings or bushings to reduce frictional resistance; alternatively, it can be an integrally formed flange on the edge of the U-shaped support slider's horizontal plate, which slides directly into the second annular guide groove. The first telescopic cylinder is an actuator that drives the piston rod to extend and retract using compressed air. Its function is to drive the air-blowing discharge block to extend or retract at specific times, thereby achieving automatic air-blowing discharge of the broiler V-bone. The first telescopic cylinder can be a single-acting or double-acting cylinder, with the air path controlled by a solenoid valve to achieve precise telescopic action; a thin or miniature cylinder can also be used to adapt to compact installation space and ensure rapid response. The air-blowing discharge block is located at the end of the telescopic rod of the first telescopic cylinder and is used to blow air onto the broiler V-bone. Its function is to blow the broiler V-bone off the placement component using high-pressure airflow after degreasing, achieving automated discharge.The air-blowing discharge block can be a hollow metal or plastic block with internal air passages and multiple high-pressure air-blowing heads on the outside; it can also be a modular component with integrated air valves and nozzles for easy installation and maintenance. The high-pressure air-blowing heads are nozzles on the air-blowing discharge block used to spray high-pressure airflow. Their function is to concentrate and accelerate compressed air to form an airflow with sufficient kinetic energy to effectively blow the broiler V-bone. The high-pressure air-blowing head can be a conical nozzle or a flat nozzle, selected according to the required blowing range and intensity; it can also be an adjustable-angle nozzle for optimized adjustment according to the shape and position of the broiler V-bone. A support rod is located in the middle of the air-blowing discharge block to support the broiler V-bone. Its function is to provide core support when the broiler V-bone is supported by the placement component, ensuring the stable placement and positioning of the broiler V-bone. The support pole can be a stainless steel pole with a polished surface to reduce damage to the broiler's V-bone and facilitate cleaning; or it can be a food-grade plastic pole with an anti-slip texture or coating to increase friction on the broiler's V-bone and prevent it from slipping.

[0061] The solution of this application specifically designs the placement component as a U-shaped support slider. This U-shaped structure can provide stable support and restraint for the broiler V-bone. The U-shaped support slider is connected to the chain through a first connecting block and moves along the first annular guide groove. At the same time, the second connecting blocks set at the front and rear ends of its horizontal plate are embedded in the second annular guide groove, forming a double guide structure. This double guide system significantly enhances the stability of the U-shaped support slider during rotation, effectively preventing the broiler V-bone from shaking, deviating, or falling off during the degreasing and scraping process. This ensures that the degreasing mechanism can accurately and continuously degrease the V-bone, improving the uniformity and thoroughness of degreasing. In addition, the rear end of the lower surface of the U-shaped support slider integrates a first telescopic cylinder. The end of its telescopic rod is connected to an air-blowing discharge block. The air-blowing discharge block has multiple high-pressure air-blowing heads, and the middle of the air-blowing discharge block is provided with a support rod for supporting the broiler V-bone. After the degreasing process is completed, the first telescopic cylinder is activated, driving the air-blowing discharge block to extend. The high-pressure air blower then sprays a powerful airflow, quickly and thoroughly blowing the broiler V-bone off the mounting bracket and causing it to fall into the discharge conveyor belt. This integrated automated air-blowing discharge mechanism effectively solves the problems of low efficiency and secondary pollution caused by manual material handling after degreasing of broiler V-bone. It achieves full automation and efficient connection from V-bone mounting and degreasing to discharge, greatly improving the operating efficiency and hygiene level of the entire degreasing device.

[0062] The following is a specific example. The U-shaped support slider can be injection molded from food-grade polypropylene material, with its U-shaped opening facing upwards. Its internal dimensions match the shape of the V-bone of the broiler to be processed, ensuring that the V-bone can be securely embedded. The second annular guide groove can be CNC milled into two parallel annular grooves on the lower surface of the fixed base, with smooth inner walls to reduce friction. The first connecting block can be a stainless steel block, fixed to the middle of the U-shaped support slider's horizontal plate with screws, and has a hole on its side for connection to the connecting pin on the drive chain. The second connecting block can be two wear-resistant PTFE sliders, installed at the front and rear ends of the U-shaped support slider's horizontal plate, respectively. Their shape matches the cross-sectional shape of the second annular guide groove to achieve smooth sliding. The first telescopic cylinder can be a small double-acting cylinder, such as a cylinder with a stroke of 20mm and a cylinder diameter of 10mm, connected to an external air source and solenoid valve through pneumatic pipelines. The air-blowing discharge block can be a cylindrical block made of aluminum alloy, with internal air channels and four evenly spaced 2mm diameter conical high-pressure air-blowing heads along its circumference. Specifically, the high-pressure air-blowing heads can be Laval nozzles with a convergent-diffusion structure to achieve supersonic airflow and enhance the blowing effect. The mounting rod can be a 5mm diameter stainless steel rod with an electrolytically polished surface, vertically fixed at the center of the air-blowing discharge block.

[0063] Through the above technical solution, the placement component is specifically designed as a U-shaped support slider, supplemented by the cooperation of the first connecting block and the first annular guide groove, and the second connecting block and the second annular guide groove, forming a dual guiding and limiting structure. This significantly improves the operational stability of the broiler V-bone during the degreasing process, effectively preventing the V-bone from shaking or falling off during high-speed rotation and scraping, thus ensuring the accuracy and continuity of the degreasing operation. Simultaneously, the first telescopic cylinder, the air-blowing discharge block, and the high-pressure air-blowing head are integrated on the U-shaped support slider, achieving automated and highly efficient air-blowing discharge of the broiler V-bone after degreasing. This not only reduces manual intervention and labor intensity but also avoids secondary contamination that may result from manual contact, improving the hygiene standards and overall automation level of the production line. The setting of the support rod ensures the precise positioning of the broiler V-bone, and in conjunction with the high-pressure air-blowing head, makes the discharge process more thorough and rapid. Overall, this solution effectively solves the technical challenges of stable bearing and efficient automatic discharge of the broiler V-bone in the degreasing device, improving the reliability, automation level, and production efficiency of the device.

[0064] In some other embodiments, this application proposes a degreasing device for V-bones of broiler chickens, which can automatically degrease the V-bones. However, in actual operation, the lack of a real-time monitoring and feedback mechanism for the degreasing process may lead to inaccurate placement of the V-bones, poor degreasing effect, or failure to detect and handle abnormal equipment operation in a timely manner, thereby affecting degreasing efficiency and product quality.

[0065] Please continue reading. Figures 1 to 3 As shown, this application further proposes that the upper surface of the support base 1 has a placement groove 12 at the left end, the placement groove 12 is provided with a monitoring camera 13, and the upper surface of the placement groove 12 is provided with a glass cover plate 14.

[0066] The placement slot provides a pre-set, protected installation space for the monitoring camera. This slot can be an integrally formed or machined recessed area on the upper surface of the support base, its shape and size matching the monitoring camera to ensure stable installation and precise alignment. For example, the slot can be designed as a rectangular or circular groove, deep enough to accommodate the main body of the monitoring camera. The monitoring camera functions to capture real-time images or videos of the degreasing process of the broiler's V-bone or the V-bone itself. By acquiring visual information, it can be used to monitor the V-bone's positioning, the working status of the degreasing mechanism, and the degreasing effect. The monitoring camera can be an industrial-grade digital camera, such as a CMOS or CCD sensor camera, with high resolution and good low-light performance to adapt to the production environment. Alternatively, an intelligent vision sensor with a built-in image processing unit can be used for preliminary image analysis. The glass cover protects the monitoring camera from contaminants such as oil, moisture, and debris that may be present in the production environment, while allowing light to pass through, ensuring clear image acquisition by the monitoring camera. The glass cover can be made of high-strength, corrosion-resistant transparent materials, such as tempered glass or polycarbonate sheets. Its installation can employ a sealed structure, such as a sealing ring or rubber strip that fits tightly against the edge of the mounting groove, to achieve good protective performance.

[0067] This application's solution involves creating a placement slot on the left end of the upper surface of the support base and placing a monitoring camera within this slot. A glass cover is installed on the upper surface of the placement slot, allowing the monitoring camera to monitor the degreasing process of the broiler's V-bone in real time under protected conditions. As the broiler's V-bone rotates on the placement component and passes through the oil-scraping mechanism for degreasing, the monitoring camera captures image information from its fixed position. The glass cover effectively isolates oil and moisture from the production environment, ensuring the cleanliness of the monitoring camera lens and the clarity of the image, thus guaranteeing the accuracy of the monitoring data. This configuration allows operators or automated control systems to understand the degreasing status of the V-bone through visual feedback, such as whether the V-bone is correctly placed, whether the oil-scraping mechanism is working properly, and whether degreasing is complete, providing a basis for subsequent adjustments and optimizations. Compared to devices that rely solely on mechanical movement for degreasing, this solution significantly improves the intelligence level of the device and the controllability of the degreasing process by introducing visual monitoring.

[0068] In one specific implementation, a rectangular placement slot measuring 100mm x 80mm x 50mm (length x width x depth) can be integrally formed on the left end of the upper surface of the support base. A 5-megapixel industrial-grade CMOS monitoring camera can be installed within this slot. The camera is bolted to the bottom of the slot, and its focus and viewing angle are adjusted to clearly capture the movement trajectory of the broiler's V-bone in the degreasing area. A 4mm thick oil-resistant tempered glass cover covers the top of the slot. The edges of the cover are sealed to the edges of the slot using silicone sealing rings to prevent oil and moisture from entering. The surface of the glass cover can be treated with an oleophobic coating to reduce oil adhesion and facilitate cleaning.

[0069] The above technical solution introduces visual monitoring capabilities into the V-bone degreasing device for broiler chickens. A placement slot is provided on the left end of the upper surface of the support base, where a monitoring camera is installed. A glass cover provides effective protection, enabling the device to acquire real-time visual information about the V-bone degreasing process. This solves the problem of traditional degreasing devices lacking real-time monitoring, allowing operators to intuitively observe the degreasing status of the V-bone, its positioning accuracy, and the operation of the scraping mechanism. During the degreasing process, the monitoring camera continuously provides image feedback, helping to promptly identify and correct problems such as V-bone placement deviations and incomplete scraping, thereby significantly improving the accuracy and efficiency of degreasing and reducing the scrap rate. Simultaneously, the protective function of the glass cover ensures the long-term stable operation and image clarity of the monitoring camera in harsh production environments such as oil and moisture, extending the equipment's lifespan and reducing maintenance costs.

[0070] In some of the above embodiments, although a degreasing device for the V-bone of broiler chickens is proposed and a monitoring camera is set up for observation, in the actual degreasing process, if the degreasing is carried out by relying solely on manual experience or a preset fixed path, it may be difficult to accurately adapt to the individual differences in the V-bone area of ​​each chicken breast, resulting in incomplete degreasing or excessive damage to the meat quality, affecting product quality and production efficiency.

[0071] In response, this application further proposes that a monitoring camera scans the chicken breast, and an intelligent control system identifies the precise three-dimensional coordinates, contours, and fat thickness distribution of the V-bone area. Based on the three-dimensional model of the V-bone area, the control system generates a contour-following degreasing path, and the degreasing mechanism drives a high-speed rotating flexible brush to perform multiple contour-following scrapings along the planned path at an angle of 10-45 degrees to the meat surface.

[0072] A monitoring camera is used to acquire visual information about the V-bone region of the chicken breast, providing raw data for subsequent analysis and processing by the intelligent control system. This scanning can be achieved in various ways; for example, the monitoring camera can be a 2D industrial camera, reconstructing 3D information from multiple images; or it can be a 3D vision sensor, such as a structured light camera or a time-of-flight (ToF) camera, directly acquiring depth information. The intelligent control system receives the images or point cloud data obtained from the monitoring camera scan and performs advanced image processing and analysis. Its role is to accurately locate the V-bone region and quantify its geometric features and fat distribution. This recognition process can be based on a pre-trained machine learning model, for example, using a convolutional neural network (CNN) for semantic segmentation of the image to identify the V-bone region; or using point cloud processing algorithms, such as RANSAC or ICP, to extract the precise 3D coordinates and contours of the V-bone from the 3D data and combine this with grayscale or color information to estimate fat thickness. The control system uses the identified 3D model of the V-bone region to dynamically plan the most suitable degreasing path for the current chicken breast. Its function is to ensure that the scraping mechanism operates precisely along the shape of the V-bone, avoiding omissions or damage. This path generation can employ various algorithms; for example, based on CAD / CAM principles, the 3D model of the V-bone can be converted into a series of tool paths; or, robot motion planning algorithms can be used, combining the geometric features of the V-bone and the kinematic model of the scraping mechanism to generate a smooth and efficient contour-following trajectory. The scraping mechanism is the core component performing the degreasing operation, using a high-speed rotating flexible brush to scrape away fat from the V-bone area. The high-speed rotation of the flexible brush provides the necessary cutting or scraping force, while its flexibility helps adapt to irregular surfaces and reduce damage to the meat. The scraping mechanism can be driven by a servo motor, using gear or belt transmission to rotate the brush; the bristles of the flexible brush can be made of materials such as nylon, silicone, or food-grade polymers to ensure flexibility and food safety. The flexible brush maintains a specific tilt angle with the surface of the chicken breast during scraping. This tilt angle optimizes scraping efficiency and protects the meat quality. A small tilt angle (nearly parallel) may result in incomplete fat removal, while an excessively large tilt angle (nearly perpendicular) may damage the meat. This angle can be preset through the mechanical structure design of the fat removal mechanism, for example, by adjusting the angle of the brush mount; or by adjusting the posture of the fat removal mechanism in real time through the control system, for example, by using a multi-axis robotic arm to precisely control the relative angle between the brush and the meat surface. The fat removal mechanism performs repeated scraping operations on the V-bone area according to the contour-following fat removal path generated by the control system. The purpose of multiple scrapings is to ensure that the fat is completely removed while avoiding meat damage that may be caused by a single scraping. This multiple scraping can be achieved by setting the number of scrapings and the depth or pressure of each scraping by the control system; or by adjusting the rotation speed and feed rate of the brush to remove fat in a gradual manner.

[0073] This application's solution significantly improves the accuracy and efficiency of degreasing the V-bone of broiler chickens by introducing visual recognition and intelligent path planning. Specifically, when the chicken breast V-bone is placed in the device, a monitoring camera first scans the chicken breast to obtain its surface image or 3D point cloud data. This raw data is then transmitted to the intelligent control system. The intelligent control system receives and processes this data, accurately identifying the precise 3D coordinates, contour, and fat thickness distribution of the V-bone area through built-in image processing and machine learning algorithms. This process overcomes the problems of inaccurate V-bone area positioning and difficulty in fat thickness assessment in traditional methods. Based on the identified 3D model of the V-bone area, the intelligent control system further dynamically generates a contour-following degreasing path. This path is tailored to the actual shape and fat distribution of the current chicken breast V-bone, ensuring that the degreasing operation closely follows the V-bone surface for precise degreasing. Subsequently, the degreasing mechanism is activated, driving a high-speed rotating flexible brush. Under the precise commands of the intelligent control system, the flexible brush moves along a pre-planned contour-following degreasing path at a specific angle of 10-45 degrees to the meat surface, performing multiple scraping motions. This contour-following scraping method effectively removes fat from the V-bone area, while minimizing damage to the chicken breast due to the characteristics of the flexible brush and precise angle control. Through real-time feedback from monitoring cameras, the intelligent control system can also perform closed-loop control, adjusting the scraping parameters based on the actual scraping effect to ensure thorough degreasing without damaging the meat. This achieves personalized, high-precision degreasing treatment of the V-bone area for each piece of chicken breast.

[0074] The following is a specific example. As a concrete implementation, the monitoring camera can be a high-resolution industrial-grade 3D structured light camera, capable of quickly acquiring precise 3D point cloud data of the V-bone region of the chicken breast. The intelligent control system can be an embedded industrial computer running a deep learning-based image recognition algorithm, such as a pre-trained Mask R-CNN model, for accurately segmenting the V-bone region and extracting its 3D contour. Simultaneously, the system integrates a path planning module, which can fit the 3D model of the V-bone based on B-spline curves or NURBS surfaces and generate a smooth five-axis robot motion trajectory as a contour-following degreasing path. The degreasing mechanism can be mounted on a six-axis collaborative robot arm, with a high-speed rotating flexible brush at its end. The bristles of the flexible brush can be made of food-grade silicone, possessing good wear resistance and flexibility. Through precise motion control, the robot arm ensures that the flexible brush maintains a 10-45 degree angle with the chicken breast surface during the scraping process, and performs multiple reciprocating scrapings along the planned path, for example, 2-3 scrapings to ensure thorough fat removal.

[0075] Through the above technical solution, this application enables precise identification and personalized degreasing path planning for the V-bone area of ​​broiler chickens. This significantly improves the thoroughness of degreasing and avoids fat residue that may result from traditional fixed-path scraping. Simultaneously, by precisely controlling the inclination angle and contour scraping of the flexible brush, the risk of damage to the chicken breast is effectively reduced, ensuring the integrity of the meat and product quality. This solution not only improves degreasing efficiency but also reduces manual intervention, achieving automated and high-precision degreasing of the V-bone in broiler chickens.

[0076] In other embodiments, this application proposes a degreasing device for the V-bone of broiler chickens, whose scraping mechanism is designed to achieve precise degreasing of the broiler chicken's V-bone. However, in actual operation, the shape and fat distribution of the broiler chicken's V-bone may vary, and traditional scraping mechanisms are difficult to achieve precise contour-following scraping of different V-bones, which may lead to incomplete degreasing or damage to the meat quality.

Figures 1 to 4 As shown, this application further proposes that the oil scraping mechanism 7 includes an arc-shaped brush blade 71, guide rails 72 are provided at both ends of the upper surface of the extended base plate 6, a first support block 73 is provided at the middle of the rear end of the upper surface of the extended base plate 6, a multi-section telescopic cylinder 74 is embedded in the first support block 73, a moving plate 75 is provided at the end of the telescopic rod of the multi-section telescopic cylinder 74, a sliding groove (not shown) is provided at both ends of the lower surface of the moving plate 75 to cooperate with the guide rail 72, a second support block 76 is provided at both ends of the upper surface of the moving plate 75, a second telescopic cylinder 77 is embedded in the second support block 76, a moving block 78 is provided at the end of the telescopic rod of the second telescopic cylinder 77, and a sliding cylinder 79 is provided on the upper surface of the moving block 78. The sliding cylinder 79 has a lifting block 8 on its inner side, a third support block 81 on its inner side, a second motor (not shown) embedded in the inner side of the third support block 81, a turntable 82 connected to the output end of the second motor, a U-shaped block 83 on its inner side, a rotating rod 84 between the two vertical plates of the U-shaped block 83, a third motor 85 for driving the rotating rod 84 to rotate on the U-shaped block 83, a rotating block 86 sleeved on the rotating rod 84, an L-shaped support block 87 connected to the rotating block 86, an arc-shaped brush blade 81 rotatably connected to the end of the L-shaped support block 87, and a fourth motor (not shown) for driving the arc-shaped brush blade 81 to rotate on the L-shaped support block 87.

[0078] This arc-shaped brush is a brush with a curved shape. Its bristles are typically made of flexible materials and are used to contact and scrape away fat from the surface of the V-bone of broilers. Its arc design better conforms to the curvature of the V-bone, improving scraping efficiency and evenness. The bristle material can be food-grade nylon, silicone, or natural fibers. Guide rails are provided at both ends of the upper surface of the extended base plate. These guide rails are mechanical components used to guide and support the movement of the moving parts along a specific path. They can be linear guide rails, dovetail guide rails, or roller guide rails, providing precise positioning and stable support for the lateral movement of the scraping mechanism. A first support block is provided at the center of the rear end of the upper surface of the extended base plate. This first support block is a structural component used to fix and support the multi-section telescopic cylinder and can be made of metal, plastic, or composite materials. The first support block is embedded with a multi-section telescopic cylinder, which is a linear actuator with multi-stage telescopic function. It uses compressed air to drive the piston rod to extend or retract, thereby achieving a large stroke range. It can be used to provide coarse positioning or large-range lifting of the oil scraping mechanism in the vertical direction. Its implementation can include a multi-stage piston rod tandem cylinder or a sleeve cylinder. A movable plate is provided at the end of the telescopic rod of the multi-section telescopic cylinder. This movable plate is a major load-bearing component in the oil scraping mechanism, used to install the subsequent oil scraping actuator. It is usually made of lightweight, high-strength materials, such as aluminum alloy or engineering plastics. The lower surface of the movable plate has grooves on both the left and right ends that mate with the guide rail. These grooves are recesses on the lower surface of the movable plate, and their shape and size match the guide rail. Through sliding or rolling, the movable plate can perform precise linear movement on the guide rail. T-grooves, V-grooves, or rectangular grooves can be used. The upper surface of the movable plate is equipped with second support blocks at both ends. These second support blocks are structural components used to fix and support the second telescopic cylinder, and are typically mounted on the upper surface of the movable plate. The second telescopic cylinder is embedded in the second support block. This second telescopic cylinder is a linear actuator used to provide fine adjustment or small-range lifting of the oil scraping mechanism in the vertical direction. It can be implemented using a single-acting cylinder or a double-acting cylinder. A moving block is provided at the end of the telescopic rod of the second telescopic cylinder. This moving block is an intermediate connecting component in the oil scraping mechanism, used to support the sliding cylinder, and is typically made of metal or engineering plastic. A sliding cylinder is provided on the upper surface of the moving block. This sliding cylinder is a linear actuator, characterized by its piston rod not extending directly, but driving the external sliding block to move linearly through an internal sliding mechanism. It can be used to provide fine adjustment or lateral displacement of the oil scraping mechanism in the horizontal direction. It can be implemented using a rodless cylinder or a cylinder with a guide rod. A lifting block is provided on the inner side of the sliding block of the sliding cylinder. This lifting block is a component on the inner side of the sliding block of the sliding cylinder, used to support the third support block and the subsequent rotating mechanism. The inner side of the lifting block is provided with a third support block, which is a structural component used to fix and support the second motor, turntable and U-shaped block.A second motor is embedded in the inner side of the third support block. This second motor is the power source for driving the turntable to rotate and can be a stepper motor, servo motor, or DC motor. The output end of the second motor is connected to the turntable, which is a circular or disc-shaped component. The turntable is driven to rotate by the output end of the second motor, serving as a platform for the rotational movement of the oil scraping mechanism. A U-shaped block is provided on the inner side of the turntable. This U-shaped block is a structural component with a U-shaped cross-section, and a rotating rod is installed between its two vertical plates. A rotating rod, a slender rod-shaped component, is located between the two vertical plates of the U-shaped block. A third motor, which is the power source for driving the rotating rod to rotate, is provided on the U-shaped block. This third motor can be a small DC motor or stepper motor. A rotating block is sleeved on the rotating rod and is used to connect to the L-shaped support block. An L-shaped support block, a structural component with an L-shaped cross-section, is connected to the rotating block at one end. The arc-shaped brush blade is rotatably connected to the end of the L-shaped support block. A fourth motor for driving the arc-shaped brush blade to rotate is provided on the L-shaped support block. This fourth motor is the power source for driving the arc-shaped brush blade to rotate and is usually a small motor.

[0079] The scraping mechanism of this application utilizes multi-level motion control to allow the arc-shaped brush blade to flexibly adapt to the complex curvature and fat distribution of the V-shaped bone. Based on an extended base plate, guide rails at both ends of its upper surface provide a lateral movement path for the entire scraping execution unit. A first support block is fixed to the center of the rear end of the extended base plate and is embedded with a multi-section telescopic cylinder. The telescopic rod of this cylinder connects to a moving plate. Slots at both ends of the lower surface of the moving plate cooperate with the guide rails, allowing the moving plate to reciprocate horizontally along the guide rails, thus achieving coverage of the scraping mechanism along the length of the V-shaped bone. To achieve fine adjustment of the scraping mechanism in the vertical direction, second support blocks are provided at both ends of the upper surface of the moving plate, with second telescopic cylinders embedded in them. The telescopic rods of the second telescopic cylinders connect to the moving blocks, and their telescopic movements allow for vertical lifting and lowering of the scraping mechanism to adapt to changes in the height of the V-shaped bone. Furthermore, a sliding cylinder is installed on the upper surface of the moving block, with a lifting block connected to the inner side of the sliding block. This allows the oil-scraping mechanism to be finely adjusted horizontally or displaced laterally to precisely align with the width of the V-bone or perform localized oil scraping. A third support block is installed on the inner side of the lifting block, with a second motor embedded therein. The output end of the second motor is connected to a turntable. The rotation of the turntable allows the U-shaped block mounted on it to be angled, thereby changing the overall oil-scraping angle of the arc-shaped brush blade to adapt to the inclination of the V-bone. A rotating rod is installed between the two vertical plates of the U-shaped block and is driven to rotate by the third motor. A rotating block fitted on the rotating rod is connected to an L-shaped support block, the end of which is rotatably connected to the arc-shaped brush blade. A fourth motor is installed on the L-shaped support block to drive the arc-shaped brush blade to rotate at high speed. This multi-stage rotation and turning design allows the arc-shaped brush blade to not only adjust its overall angle but also rotate at high speed, thereby generating stronger scraping force during oil scraping and ensuring that the bristles can effectively remove grease. Through the coordinated operation of the above-mentioned multi-level linear and rotary motion mechanisms, the oil scraping mechanism can achieve three-dimensional contouring motion of the broiler's V-bone, precisely controlling the contact angle, pressure, and scraping path between the arc-shaped brush and the V-bone surface.

[0080] The following is a specific example: the bristles of the arc-shaped brush blade in the oil scraping mechanism can be made of food-grade wear-resistant nylon, and its curvature design matches the typical V-shaped surface of a broiler's bone. The guide rails on both sides of the upper surface of the extension base plate can be high-precision ball-bearing linear guides to ensure smooth and precise movement of the moving plate. The first and second support blocks can be made of stainless steel or aluminum alloy and are bolted to the extension base plate and the moving plate. The multi-section telescopic cylinder can be a multi-stage cylinder with a stroke of 100-200mm to provide a large vertical adjustment range; the second telescopic cylinder can be a precision cylinder with a stroke of 20-50mm for fine adjustment of the oil scraping height. The moving plate and moving blocks can be made of lightweight, high-strength aluminum alloy. The sliding cylinder can be a rodless cylinder to achieve compact lateral movement. The second and third motors can be stepper motors or servo motors to achieve precise angle positioning and speed control; the turntable can be made of aluminum alloy or engineering plastics. The U-shaped block and L-shaped support block can be made of stainless steel or high-strength engineering plastics. The rotating rod can be made of stainless steel. The fourth motor can be a high-speed DC brushless motor, which directly drives the arc-shaped brush blade to rotate at high speed to provide sufficient scraping force.

[0081] Through the aforementioned technical solution, the oil-scraping mechanism possesses multi-dimensional and high-precision motion capabilities, enabling precise contour-following oil scraping from the broiler's V-bone. The combination of multi-section telescopic cylinders, a second telescopic cylinder, and a sliding cylinder allows for a wide range of precise adjustments in both vertical and horizontal directions to adapt to different V-bone heights and widths. A second motor drives the turntable to rotate, and a third motor drives the rotating rod to rotate, in conjunction with a fourth motor driving the arc-shaped brush blade to rotate itself. This collectively achieves multi-angle and multi-axial movement of the arc-shaped brush blade in space, allowing it to closely conform to the complex curves of the V-bone and scrape oil at the optimal angle. This precise motion control and multi-level adjustment capability effectively solves the problems of incomplete oil removal or meat damage in traditional oil-scraping mechanisms when processing different V-bones, significantly improving oil removal efficiency and quality, and ensuring the integrity of the broiler's V-bone and product quality.

[0082] In some other embodiments, this application proposes a degreasing device for the V-bone of broiler chickens, whose degreasing mechanism includes an arc-shaped brush. This arc-shaped brush is precisely controlled through a series of complex mechanical structures to achieve degreasing of the broiler chicken's V-bone. However, in actual degreasing, the fat distribution on the surface of the broiler chicken's V-bone is uneven, and the V-bone structure is complex. Brush bristles of a single material or rigidity may be insufficient to simultaneously achieve the initial stripping of large areas of fat and the fine scraping of residual fat at edges and crevices, easily leading to incomplete degreasing or unnecessary damage to the meat quality.

[0083] In this regard, this application further proposes that the bristles of the aforementioned arc-shaped brush blade adopt an inner and outer partition design, with the inner bristles being softer and used for initial peeling and adsorption; the outer bristles having higher rigidity and used for fine scraping and cleaning edges.

[0084] The bristle zoning design of the curved brush blade refers to dividing the bristles into different zones according to their radial position on the brush head. Each zone of bristles has different physical properties or functions. This design aims to optimize the contact and effect between the bristles and the treated object (chicken V-bone) to adapt to different degreasing needs. The softer inner bristles, located in the central area of ​​the curved brush blade, are selected for their material, diameter, length, or density to ensure lower stiffness when contacting the chicken V-bone. These softer bristles gently contact the V-bone surface, reducing impact on the meat. Their main function is to initially remove most of the fat adhering to the V-bone surface, and then absorb or remove the removed fat through the bristles' flexibility. Achieving softer bristles can include using materials such as silicone, soft nylon, or natural fibers, or employing finer bristle diameters, longer bristle lengths, or lower bristle densities. The higher-stiffness outer bristles, located in the outer perimeter of the curved brush blade, have significantly higher stiffness than the inner bristles. These high-rigidity bristles provide stronger scraping force, primarily used for fine scraping away stubborn fat remaining on the surface of the V-bone, and effectively cleaning fat from hard-to-reach areas such as the edges and depressions of the V-bone. Achieving higher bristle rigidity can be achieved by using materials such as stiff nylon, polypropylene, or carbon fiber, or by using coarser bristle diameters, shorter bristle lengths, or higher bristle density.

[0085] This application's solution employs an inner and outer section design for the bristles of the curved brush, enabling differentiated processing strategies during the degreasing process based on the varying states and locations of fat on the V-bone surface. When the curved brush, driven by the degreasing mechanism, contacts the broiler's V-bone, the softer inner bristles initially make contact. These inner bristles, with their lower stiffness, gently conform to the curve of the V-bone, initially peeling and adsorbing large areas of fat adhering to the V-bone surface, avoiding excessive friction and damage to the meat. As the curved brush moves further, the outer bristles, with higher stiffness, come into play. These outer bristles provide stronger mechanical scraping force, precisely scraping and cleaning residual fat that the inner bristles could not completely remove, especially in hard-to-reach areas such as the V-bone edges and crevices. This synergistic mechanism of inner and outer bristles allows the curved brush to efficiently remove most of the fat in a single scraping cycle, ensuring thorough cleaning of detailed areas while maximizing the preservation of the meat's integrity. This design allows the oil-scraping mechanism to adapt more effectively to the complex geometry and fat distribution of the chicken's V-bone, achieving a comprehensive and precise oil removal effect.

[0086] The following is a specific example. As a concrete implementation, the bristles of the curved brush blade can be designed as follows: The inner ring bristles can be made of food-grade silicone, with a finer diameter and relatively longer length to provide sufficient flexibility and adsorption capacity. These silicone bristles are arranged at a lower density in the central area of ​​the curved brush blade, forming a soft contact surface. The outer ring bristles can be made of high-strength nylon, with a coarser diameter and relatively shorter length to provide higher rigidity and scraping force. These nylon bristles are arranged at a higher density in the outer area of ​​the curved brush blade, forming a tough cleaning edge. When the oil-scraping mechanism drives the curved brush blade to rotate and move along the planned path, the inner ring silicone bristles first gently contact the V-bone, peeling off and adsorbing most of the fat; subsequently, the outer ring nylon bristles, with their stronger scraping force, thoroughly and finely scrape away the edges of the V-bone and residual fat. A fourth motor mounted on the L-shaped support block can drive the curved brush blade to rotate at an appropriate speed to optimize the contact effect between the bristles and the V-bone.

[0087] Through the aforementioned technical solution, the bristles of the arc-shaped brush blade adopt an inner and outer zone design. The inner bristles are softer and used for initial peeling and adsorption, while the outer bristles have higher rigidity and are used for fine scraping and cleaning the edges. This design allows the oil-scraping mechanism to provide phased and differentiated oil removal based on the adhesion state of fat and the structural characteristics of the V-bone in broiler chickens. The softer inner bristles effectively avoid damage to the meat while efficiently removing large areas of loose fat; while the high-rigidity outer bristles ensure thorough removal of stubborn fat from hard-to-reach areas such as the edges and crevices of the V-bone. This significantly improves the efficiency and thoroughness of oil removal, reduces meat loss, and thus improves the overall quality and economic benefits of oil removal from the V-bone of white-feathered broiler chickens.

[0088] In other embodiments, this application proposes a degreasing device for V-bones of broiler chickens. The device includes a support base, a support rod, a fixed seat, a first annular guide rail groove, a placement component, a driving component, a discharge conveyor belt, an extended base plate, and an oil scraping mechanism. The oil scraping mechanism includes an arc-shaped brush blade. Guide rails are provided at both ends of the upper surface of the extended base plate. A first support block is provided at the center of the rear end of the upper surface of the extended base plate. Multiple telescopic cylinders are embedded in the first support block, and a movable plate is provided at the end of the telescopic rod of each telescopic cylinder. The lower surface of the movable plate has grooves on both the left and right ends that mate with the guide rail. The upper surface of the movable plate has second support blocks on both the left and right ends. A second telescopic cylinder is embedded in the second support block. A moving block is provided at the end of the telescopic rod of the second telescopic cylinder. A sliding cylinder is provided on the upper surface of the moving block. A lifting block is provided on the inner side of the sliding block of the sliding cylinder. A third support block is provided on the inner side of the lifting block. A second motor is embedded on the inner side of the third support block. The output end of the second motor is connected to a turntable. A U-shaped block is provided on the inner side of the turntable. A rotating rod is provided between the two vertical plates of the U-shaped block. A third motor for driving the rotating rod to rotate is provided on the U-shaped block. A rotating block is sleeved on the rotating rod. An L-shaped support block is connected to the rotating block. The arc-shaped brush blade is rotatably connected to the end of the L-shaped support block. A fourth motor for driving the arc-shaped brush blade to rotate is provided on the L-shaped support block.

[0089] In some embodiments described above in this application, an oil-scraping mechanism for degreasing the V-bone of broiler chickens is proposed. This mechanism uses a moving plate to drive an arc-shaped brush blade to perform the oil-scraping operation. However, during the oil-scraping process, the scraped-off grease and debris may scatter on the moving plate, causing contamination of the working area, affecting the cleanliness of the equipment, and potentially interfering with subsequent oil-scraping operations, thus reducing the overall oil-removal efficiency.

[0090] Please continue reading. Figure 1 and Figure 3 As shown, this application further proposes that a support frame 9 is provided in the middle of the upper surface of the aforementioned movable plate 75, and a U-shaped guide discharge plate 91 is inclinedly provided on the support frame 9.

[0091] The support frame is a structural component used to support and secure other parts. Its function is to provide a stable mounting base and suitable height for the U-shaped guide discharge plate. This support frame can be, for example, a frame structure welded from metal profiles, or a support structure composed of multiple columns to ensure sufficient mechanical strength and stability. The inclined setting refers to the U-shaped guide discharge plate having a preset angle relative to the horizontal plane. This inclined design utilizes gravity or the inertial force of the material to effectively guide the scraped grease and debris to flow in a specific direction. The inclined setting can be achieved by adjusting the height difference of the support frame so that one end of the U-shaped guide discharge plate is higher than the other, or by designing the support frame itself with an inclined angle. The U-shaped guide discharge plate is a plate-like structure with a U-shaped cross-section. Its main function is to collect and guide the grease and debris generated during the scraping process, allowing them to be discharged in a concentrated and orderly manner. This guide discharge plate can be integrally formed from corrosion-resistant food-grade materials (such as stainless steel plates) through stamping or bending processes. The inner surface of its U-shaped channel can be polished to reduce material flow resistance and ensure smooth discharge.

[0092] In the aforementioned broiler V-bone degreasing device, the oil scraping mechanism uses a moving plate to drive an arc-shaped brush to remove oil from the broiler V-bone. During the scraping process, grease, debris, and other waste scraped from the V-bone surface naturally fall to the area above the moving plate. To effectively manage this waste, a support frame is provided in the middle of the upper surface of the moving plate. This support frame stably supports the U-shaped guide discharge plate. The U-shaped guide discharge plate is inclined on the support frame, with its U-shaped groove facing the oil scraping area, effectively collecting grease and debris that fall off or splash from the arc-shaped brush. Due to the inclination angle of the U-shaped guide discharge plate, the collected waste automatically slides towards the lower end along the direction of the U-shaped groove under gravity, thus being guided to a preset collection area or container. This design ensures that the waste generated during the oil scraping process can be discharged from the working area in a timely and effective manner, avoiding the accumulation of waste on the moving plate, thereby maintaining the cleanliness of the equipment, preventing secondary contamination of the broiler V-bone, and ensuring the continuous and efficient operation of the oil scraping mechanism.

[0093] In one specific implementation, two vertical support rods can be welded to the center of the upper surface of the movable plate as a support frame. These two support rods have different heights, causing the plate to exhibit a certain tilt angle when the U-shaped guide discharge plate is fixed at its upper end. The U-shaped guide discharge plate can be made of stainless steel sheet of appropriate thickness, formed into a U-shaped channel structure with a smooth inner wall through a cold bending process. The length of the U-shaped guide discharge plate can be matched to the effective oil scraping stroke of the movable plate, and its width is sufficient to cover the area where waste may be scattered in the oil scraping area. The tilt angle can be set to, for example, 8 degrees, to ensure that grease and debris can slide off quickly under their own weight.

[0094] By installing a support frame in the middle of the upper surface of the moving plate and tilting a U-shaped guide discharge plate on the support frame, the degreasing device of this application can effectively collect and guide the grease and debris generated during the scraping process. This significantly solves the problem of waste accumulation on the moving plate, avoids contamination of the working area and secondary contamination of the broiler V-bone, thereby improving the hygiene level and degreasing efficiency of the equipment. At the same time, because the waste is discharged in a timely manner, the frequency and difficulty of manual cleaning are reduced, maintenance costs are lowered, and the stable and continuous operation of the scraping mechanism is ensured, further enhancing the automation level and production efficiency of the entire broiler V-bone degreasing device.

[0095] In other embodiments, this application proposes a degreasing device for broiler V bones, which uses a mechanical structure to transport and scrape oil from the broiler V bones. However, since the shape, size, and fat distribution of each broiler V bone vary, traditional fixed-path or manually adjusted degreasing methods are difficult to ensure thorough degreasing and can easily damage the meat quality, affecting product quality and production efficiency.

[0096] In this regard, this application further proposes that the device also includes a control system, which is pre-installed with a V-bone region recognition and path planning algorithm based on machine learning training; its workflow is as follows: receiving three-dimensional point cloud data → identifying and locating the boundary of the V-bone region and the fat thickness distribution → planning the optimal degreasing path (contour path) → coordinating the control of the oil scraping mechanism to drive the brush to move along the planned path at a specific angle, pressure and speed, while controlling the clamping unit to make adaptive fine adjustments → performing closed-loop control based on visual feedback to ensure thorough degreasing without damaging the meat.

[0097] The control system is the core unit responsible for the overall operation management, data processing, decision-making, and command execution of the device. This control system can use an industrial PC (IPC) or programmable logic controller (PLC) as its hardware platform, equipped with a corresponding operating system and control software to achieve complex logic control and data processing functions. Alternatively, the control system can employ an embedded system, such as a customized control board based on a high-performance microcontroller (MCU) or digital signal processor (DSP), to achieve more compact and efficient control. The V-bone region recognition and path planning algorithm based on machine learning training is an intelligent algorithm that automatically identifies the V-bone region, analyzes fat distribution, and generates the optimal fat-scraping path by learning from a large amount of sample data. This algorithm can use deep learning models, such as convolutional neural networks (CNNs), for image recognition and feature extraction, combined with path planning algorithms (such as A* or RRT algorithms) to generate contour-following paths. Alternatively, the algorithm can use traditional machine learning methods such as support vector machines (SVMs) or decision trees for V-bone region classification and recognition, combined with geometric modeling and optimization algorithms for path planning.

[0098] The purpose of receiving the 3D point cloud data is to obtain precise 3D geometric information of the broiler's V-bone surface, providing foundational data for subsequent identification and planning. This can be achieved by scanning the broiler's V-bone with a structured light scanner or LiDAR sensor to obtain dense point cloud data of its surface. Alternatively, a multi-view stereo vision system can be used, capturing images from different angles using multiple cameras, and then generating point cloud data through image processing and 3D reconstruction algorithms. The identification and localization of the V-bone region boundary and fat thickness distribution is based on the 3D point cloud data, precisely determining the extent of the V-bone region and quantifying the fat thickness distribution within that region. This can be achieved using point cloud segmentation algorithms (such as RANSAC and region growing) to separate the V-bone region from the background, and then using machine learning models to perform feature analysis on the segmented region to identify boundaries and fat thickness. Alternatively, image processing techniques can be combined, projecting the 3D point cloud onto a 2D plane for processing, using edge detection and morphological operations to identify boundaries, and estimating fat thickness using color, texture, or spectral information.

[0099] The planned optimal degreasing path (contouring path) is generated based on the identified V-bone region boundary and fat thickness distribution, creating a path that is efficient, thorough, and does not damage the meat. This can be achieved using a CNC machining toolpath planning algorithm based on a 3D model of the V-bone and a fat distribution map, generating a contouring path composed of multiple curve or straight line segments. Alternatively, optimization algorithms (such as genetic algorithms or particle swarm optimization) can be used to search for the optimal degreasing path while satisfying the constraints of thorough degreasing and avoiding damage to the meat. The coordinated control of the degreasing mechanism drives the brush blade to move along the planned path at a specific angle, pressure, and speed, aiming to precisely drive the degreasing mechanism according to the planned path, so that the brush blade performs degreasing operations with optimal posture and parameters. This can be achieved by controlling multiple degrees of freedom of the degreasing mechanism (such as XYZ axis movement and rotation angle) through servo motors or stepper motors, realizing precise position, angle, and speed control of the brush blade. At the same time, force sensors can be used to monitor the contact pressure between the brush blade and the meat surface in real time, and the Z-axis position or cylinder pressure of the degreasing mechanism can be adjusted through closed-loop control to maintain a constant degreasing pressure.

[0100] The simultaneous adaptive fine-tuning of the clamping unit aims to make real-time and precise adjustments to the clamping state of the broiler's V-bone during the oil scraping process, ensuring the stability and effectiveness of oil scraping. This can be achieved by using sensors (such as force sensors and displacement sensors) installed on the clamping unit to sense changes in the force or position of the V-bone in real time, controlling the clamping cylinder or motor to make minute adjustments to the position or clamping force. Alternatively, a visual feedback system can be used to monitor the posture of the V-bone during the oil scraping process and make compensatory adjustments to the clamping unit based on posture deviations. The closed-loop control based on visual feedback involves acquiring visual information during the oil scraping process in real time, evaluating the oil scraping effect, and adjusting control parameters accordingly to form a feedback loop, improving the accuracy and robustness of oil scraping. This can be achieved by installing an industrial camera above or to the side of the oil scraping area to capture images of the oil scraping process in real time, analyzing the oil scraping effect (such as residual fat and meat damage) using image processing algorithms, and feeding the results back to the control system for parameter correction. Alternatively, a depth camera can be used to acquire three-dimensional surface data after oil scraping, compare it with a preset ideal model, calculate the deviation, and adjust the oil scraping parameters until the desired effect is achieved. Ultimately, ensuring thorough degreasing without damaging the meat is the ultimate goal and effect of the entire control system, achieved through the aforementioned series of intelligent control and feedback mechanisms.

[0101] The control system of this application, as the intelligent core of the device, receives three-dimensional point cloud data of the broiler V-bone and uses a pre-set machine learning algorithm to perform in-depth analysis of this data, accurately identifying the boundaries and fat thickness distribution of the V-bone region. Based on this refined information, the control system can plan an optimal contour-following degreasing path for each broiler V-bone with a unique shape and fat distribution. This path not only considers the complex curvature of the V-bone but also dynamically adjusts the depth and force of the degreasing based on the fat thickness. Subsequently, the control system precisely coordinates and controls the degreasing mechanism, causing it to drive the brush blade to move along the planned path at a specific angle, pressure, and speed, achieving precise degreasing. During this process, the placement component, acting as a clamping unit, undergoes adaptive fine-tuning under the instructions of the control system to ensure that the broiler V-bone maintains optimal stability and posture throughout the degreasing process. Simultaneously, the control system monitors the degreasing effect in real time through continuous visual feedback. Once any residual fat or potential meat quality damage risk is detected, the control system immediately performs closed-loop adjustments, correcting the motion parameters of the degreasing mechanism or fine-tuning the clamping unit until the goal of thorough degreasing without damaging the meat is achieved. This intelligent control process enables the device to perform personalized and precise processing on each chicken V-bone, significantly improving the thoroughness and efficiency of degreasing while maximizing the preservation of the meat's integrity.

[0102] In one specific implementation, when the broiler's V-bone is placed on the placement device and enters the degreasing area, a monitoring camera located in the placement slot can perform a 3D scan of the broiler's V-bone, acquiring its high-precision 3D point cloud data. This data is transmitted to the control system. A pre-installed V-bone region recognition and path planning algorithm based on machine learning training within the control system is then activated to analyze the received 3D point cloud data. This algorithm first accurately identifies the boundary of the broiler's V-bone region and generates a fat thickness distribution map of that region. For example, the algorithm can identify that the fat accumulation at the edge of the V-bone region is thicker, while the fat in the central region is thinner. Based on this detailed information, the control system plans an optimal contour-following degreasing path in real time. This path accurately follows the complex curvature of the V-bone and adjusts the depth and force of the scraping according to the fat thickness. Subsequently, the control system coordinates with the scraping mechanism to drive the arc-shaped brush blade to perform multiple scraping operations along the planned contour-following path at a preset angle of 10-45 degrees, with appropriate pressure and rotation speed. During this process, the placement unit acts as a clamping unit, and its first telescopic cylinder and air-blowing discharge block can be adaptively fine-tuned according to the instructions of the control system to ensure that the broiler's V-bone maintains the optimal posture during the oil removal process. Simultaneously, the control system provides closed-loop control of the oil removal process through continuous visual feedback (e.g., monitoring the oil removal effect through additional visual sensors). If the vision system detects residual fat or potential meat damage, the control system immediately adjusts the motion parameters of the oil removal mechanism or the fine-tuning of the placement unit until the goal of thorough oil removal without damaging the meat is achieved.

[0103] Through the above technical solution, the degreasing device for broiler V bones of this application can overcome the problems of incomplete degreasing or damage to meat quality caused by the large individual differences in broiler V bones in traditional degreasing methods. By introducing an intelligent control system and machine learning algorithms, the device can perform personalized and refined degreasing treatment on each broiler V bone, significantly improving the thoroughness and efficiency of degreasing, while maximizing the protection of the meat integrity, avoiding economic losses caused by excessive scraping, and improving product quality and the automation level of the production line.
