Description

Technical Field

[0001] This application relates to the field of poultry slaughtering and processing equipment, and more specifically, to a broiler lifting machine. Background Technology

[0002] In the poultry slaughtering and processing industry, the processing of broiler chickens involves several key steps, including lifting, conveying, evisceration, and evisceration. Traditional methods rely on decentralized equipment or manual operation to complete these processes. For example, broiler chickens are first transported to a fixed height by an independent lifting device, then transferred to an evisceration station via conveyor belt for cutting, and subsequently moved to another area for evisceration operations such as lung suction. This process design results in a loose production line layout, occupies a large amount of factory space, and easily introduces the risk of cross-contamination when frequently transferring broiler chickens between processes, affecting product hygiene, safety, and quality consistency. At the same time, broiler chickens vary significantly in size, and existing fixed-height conveying equipment cannot dynamically adapt to the optimal processing position for chickens of different sizes, resulting in uneven evisceration depths, which may damage the meat or lead to incomplete cutting, thereby shortening the life of the cutting tools. Although some automated devices have attempted to introduce height adjustment mechanisms, their structures are often too complex, the adjustment process is unstable, and the response is slow, making it difficult to coordinate with subsequent cutting and cleaning stations and achieve continuous and smooth integrated operations. Especially in the two core pre-processing stages of abdominal opening and lung suction, the independent setup of the equipment forces broilers to undergo multiple handling processes, which not only prolongs the processing cycle and reduces production efficiency, but also causes a decrease in operational precision due to positional shifts. Furthermore, the fixed installation of the cutting and cleaning components lacks the ability to fine-tune according to the size of the chickens, further exacerbating the problem of unstable processing results.

Detailed Implementation

[0023] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0024] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] In automated poultry slaughtering and processing equipment, existing technologies suffer from discontinuous process connections. Specifically, key pre-processing steps such as lifting, abdominal opening, and visceral cleaning are often configured as independent workstations, resulting in broilers undergoing multiple transfers during transport. Furthermore, the insufficient adaptability of the height adjustment mechanism makes it difficult for the equipment to dynamically adjust the processing position according to the broiler's body size, thus affecting cutting accuracy and cleaning effectiveness. Additionally, the dispersed layout of workstations increases transport distances and the number of devices, thereby limiting production efficiency, increasing the difficulty of hygiene control, and reducing equipment stability due to frequent transfers.

[0026] For example, on a broiler slaughtering production line, broilers are conveyed to a fixed height by an elevator and then transferred to a separate abdominal cutting station. Because the abdominal cutting equipment is in a fixed position, when processing broilers of varying sizes, the relative position of the cutting blade and the broiler shifts, resulting in inconsistent cutting depths. Subsequently, the broilers are transferred to another lung removal station for lung removal. During this transfer, the broilers come into contact with unclean surfaces, increasing the risk of microbial contamination. Specifically, the positional shift during transfer leads to insufficient matching between the cutting tool and the individual broiler, making thorough cleaning impossible. This results in decreased product hygiene quality and increased equipment maintenance frequency.

[0027] If these issues are not addressed, the lack of coordination between processes will lead to increased volatility in product quality and a significant increase in hygiene risks. This will result in a continuous increase in equipment maintenance needs, disruption of production continuity, and consequently, impact on overall production efficiency. Furthermore, inaccuracies in cutting and cleaning operations will cause product damage, reduce product yield, and potentially lead to more frequent equipment failures.

[0043] Cleaning component: Located at the rear end of the U-shaped support frame, it is used to perform cleaning operations such as sucking out the lungs after the broiler is opened, to ensure the hygiene of the meat.

[0044] This embodiment provides a broiler elevator, whose structural design aims to achieve automated and continuous processing of broilers.

[0045] The broiler elevator includes a support frame, which serves as the basic framework of the entire equipment. This frame can be constructed using various methods, such as welded steel structures or modular aluminum alloy profiles, to provide sufficient strength and stability. Guide rails are installed at both ends of the upper surface of the support frame. These guide rails can be linear guides, V-shaped guides, or sliding grooves, and their function is to provide precise movement paths for subsequent moving parts.

[0046] On the left and right rear ends of the upper surface of the support frame, there are first support rods. These first support rods can take the form of vertical columns or fixed brackets, and their main function is to provide support for the vertical position adjustment of the U-shaped support frame. The inner surface of each first support rod is provided with a first strip-shaped groove, which can be a simple rectangular groove or a dovetail groove, to accommodate and guide the internal transmission mechanism.

[0047] A first synchronous motor, which can be a stepper motor or a servo motor, is installed within the first groove, enabling precise position control. The output end of the first synchronous motor is connected to a first screw, which can be a trapezoidal screw or a ball screw, converting the motor's rotational motion into linear motion. A first moving block, which can be a nut seat or a slider, is helically fitted onto the first screw, moving up and down with the rotation of the first screw. A U-shaped support frame connects the first moving blocks at both ends. This U-shaped support frame can be a U-shaped structure welded from metal sheets or profiles, and its connection to the first moving blocks enables overall vertical lifting.

[0048] A movable plate, which can be a flat plate or a frame structure, is slidably mounted on a guide rail and moves back and forth on a support frame guided by the guide rail. A multi-section telescopic cylinder is installed at the rear end of the middle section of the upper surface of the support frame. This multi-section telescopic cylinder can be a double-acting cylinder or a multi-stage cylinder, which drives the extension or retraction of a telescopic rod via air pressure. The end of the telescopic rod of the multi-section telescopic cylinder is connected to the movable plate, for example, via a pin or bolt, thereby enabling the movable plate to be pushed or pulled back and forth.

[0049] The upper surface of the movable plate is provided with first support blocks at both ends. These first support blocks can be fixed seats or ear plates, used to establish a connection with the U-shaped support frame. The first support blocks are rotatably hinged to the front ends of the two vertical plates of the U-shaped support frame, for example, by means of pins or pivots, so that the U-shaped support frame can tilt and rotate around the hinge point as the axis.

[0050] The upper part of the U-shaped support frame is equipped with a roller conveyor belt for transporting broilers. This roller conveyor belt can be composed of a series of parallel rollers, which are driven by a motor to rotate, thereby transporting the broilers from the feeding end to the discharging end. The front end of the U-shaped support frame is equipped with a cutting device for opening the broiler's abdomen during transport. This cutting device can be a fixed blade or a rotating cutter, and its function is to cut the abdomen of the broiler as it passes through. The rear end of the U-shaped support frame is equipped with a cleaning device for sucking the lungs from the broiler's interior. This cleaning device can be a suction nozzle or a scraper device, and its function is to clean the inside of the broiler after it has been opened.

[0051] The following example will provide a more detailed explanation of the above technical solution: Imagine a broiler slaughtering and processing plant that needs to automate the lifting, evisceration, and lung removal processes for a batch of chickens of different sizes. Traditional methods might require workers to manually transfer the chickens from one workstation to another, or use multiple separate pieces of equipment, which is inefficient and prone to contamination.

[0052] The broiler elevator provided in this embodiment is deployed on a processing line. When a batch of broilers needs to be processed, the broilers are first placed on a roller conveyor belt within a U-shaped support frame. The roller conveyor belt then starts running, transporting the broilers from the feed end to the discharge end.

[0053] As the broiler chickens are conveyed to the front of the U-shaped support frame, their abdomens pass over the cutting device. The cutting device is pre-positioned to perform the abdominal opening operation. Because different batches of broiler chickens may vary in size, the operator can adjust the overall position of the U-shaped support frame via the control system to ensure accurate cutting. Specifically, by driving the first synchronous motor, the first screw connected to its output end rotates, thereby causing the first moving block, which is spirally mounted on the first screw, to move up and down. Since the U-shaped support frame is connected between the first moving blocks at both ends, the overall height of the U-shaped support frame can be precisely adjusted to accommodate the cutting needs of broiler chickens of different sizes.

[0054] After the abdominal incision is completed, the broilers continue to be conveyed by a roller conveyor to the rear end of the U-shaped support frame. Here, the cleaning unit performs a lung suction operation on the broilers' interior. Similarly, to accommodate different internal structures and processing requirements of broilers, the tilt angle and front-to-back position of the U-shaped support frame also need to be adjusted. Through the connection between the end of the telescopic rod of the multi-section telescopic cylinder and the moving plate, the multi-section telescopic cylinder can push or pull the moving plate to slide on the guide rail on the upper surface of the support frame, thereby realizing the overall front-to-back movement of the U-shaped support frame. At the same time, since the first support blocks at both ends of the upper surface of the moving plate are rotatably hinged to the front ends of the two vertical plates of the U-shaped support frame, combined with the adjustment of the height of the U-shaped support frame by the first synchronous motor and the first screw, the U-shaped support frame can be tilted from front to back and upward, thereby optimizing the processing posture of the broilers at the cleaning unit and ensuring the thoroughness of the lung suction operation.

[0055] Thus, broiler chickens undergo a continuous process of lifting, abdominal dissection, and lung suction on a U-shaped support frame, eliminating the need for manual transfer or multiple separate devices. The entire process is completed on an integrated platform, significantly improving processing efficiency and hygiene.

[0056] Based on the above examples, the broiler elevator of this embodiment demonstrates significant technological contributions. Compared to the dispersed and independent broiler processing steps in the prior art, this application integrates multiple key steps such as broiler conveying, evisceration, and lung suction onto a single U-shaped support frame, achieving continuous and integrated processing. For example, in the prior art, broilers need to be transferred to a separate cleaning station after evisceration, which not only increases the transmission distance and the number of devices but may also cause contamination during the transfer process. In this embodiment, however, the broilers move continuously on a roller conveyor belt, passing through the cutting and cleaning sections sequentially, avoiding intermediate transfer steps, thereby effectively reducing the risk of cross-contamination and improving production efficiency.

[0057] Furthermore, this embodiment achieves flexible adjustment of the height and tilt angle of the U-shaped support frame through a combination of a first synchronous motor, a first screw, a first moving block, a multi-section telescopic cylinder, a moving plate, and a rotating hinge. In existing technologies, equipment often struggles to adapt flexibly to the optimal processing height for broilers of different sizes, leading to inaccurate cutting or cleaning positions. This embodiment, however, can precisely adjust the vertical position and tilt angle of the U-shaped support frame according to the actual size of the broiler, ensuring that the cutting and cleaning components are always in the optimal working position. This guarantees consistency in abdominal opening depth and thoroughness of lung suction, significantly improving processing efficiency and product quality. This integrated and adjustable design effectively solves the technical problems of inefficient process flow, large footprint, high difficulty in hygiene control, and poor processing results in existing technologies.

[0058] In some embodiments described above in this application, a broiler lifting machine is proposed, which processes broilers by moving and tilting a U-shaped support frame in conjunction with a roller conveyor belt, a cutting component, and a cleaning component. However, during the lifting, conveying, and processing of broilers, the broilers themselves or debris and liquids generated during processing may fall from the sides of the support frame, causing environmental pollution or material loss, and affecting the cleanliness and efficiency of the production line.

[0059] Please continue reading. Figures 1 to 6 As shown, this application further proposes that protective barriers 10 be provided at both ends of the upper surface of the support frame 1. A protective barrier is a physical barrier installed at the edge of equipment to prevent objects from falling or spilling off the equipment. This protective barrier can be implemented in various forms. For example, it can be made of corrosion-resistant metal materials (such as stainless steel) and securely fixed to the edge of the upper surface of the support frame by welding or bolting. Alternatively, the protective barrier can be made of high-strength engineering plastic sheets and installed by slots or riveting to provide a lightweight and easy-to-clean solution. In some embodiments, the protective barrier can also be designed as a detachable or flip-up structure to facilitate equipment maintenance, cleaning, or adjustment under specific operating conditions.

[0060] The solution proposed in this application effectively constructs a physical barrier by installing protective fences at both ends of the upper surface of the support frame. When broilers are conveyed on the roller conveyor belt on the U-shaped support frame and undergo abdominal cutting or lung suction by the cleaning unit, any debris, feathers, blood, or rinsing fluids generated during processing, even if accidentally spilled or fallen from the sides of the U-shaped support frame, will be blocked by the protective fences on the upper surface of the support frame. The protective fences confine these falling objects within the support frame, preventing them from scattering onto the work area or ground outside the equipment. This design ensures the cleanliness and hygiene of the entire broiler processing process, avoids pollution of the surrounding environment, and reduces cleaning workload. In this way, the protective fences, combined with the core processing function of the broiler elevator, jointly maintain a clean and safe production environment.

[0061] In one specific implementation, the protective fence can be made of stainless steel sheets of moderate thickness, with a height sufficient to effectively prevent spillage of liquids and debris generated during the processing of broiler chickens. These stainless steel sheets are connected by welding or bolting, extending upwards along the edges of the left and right ends of the upper surface of the support frame to form a continuous enclosure structure. For example, the protective fence can be designed with an inner wall at a certain angle to facilitate liquid backflow into the support frame or a pre-designated collection area, further improving cleaning efficiency. Furthermore, the surface of the protective fence can be polished to reduce bacterial adhesion and facilitate daily rinsing and disinfection.

[0062] Through the above technical solution, the protective railings installed at both ends of the support frame on the left and right sides during broiler processing operations on the broiler elevator effectively prevent broilers, their debris, liquids, etc., from falling or spilling from the sides of the equipment. This significantly improves the cleanliness and hygiene of the production environment, avoids pollution to the surrounding area, and reduces the risk of cross-contamination. At the same time, it reduces the amount of cleaning and maintenance work caused by material spillage, and improves the overall operating efficiency of the equipment and the hygiene standards of the production line.

[0063] In some embodiments described above in this application, a broiler elevator is proposed, wherein a U-shaped support frame is connected to the support frame via a first synchronous motor and a multi-section telescopic cylinder, for conveying broilers and performing operations such as abdominal dissection and lung suction. However, in actual broiler processing, the posture of the U-shaped support frame may need to be adjusted according to different processing requirements or to facilitate liquid drainage, in order to optimize the conveying and processing effect of the broilers.

[0064] Please continue reading. Figures 1 to 3 As shown, this application further proposes that the U-shaped support frame 1 is tilted from front to back and upward through the action of multiple telescopic cylinders 15 and the first synchronous motor.

[0065] The U-shaped support frame is the core load-bearing component of the broiler elevator. It contains a roller conveyor belt for transporting broilers and has cutting and cleaning components at its front and rear ends for opening the broilers' bellies and sucking their lungs. The U-shaped support frame's structural design allows it to stably support these components and connects to the support frame via a rotating hinge and a moving block, allowing for posture adjustments. A multi-section telescopic cylinder is an actuator capable of multi-stage telescopic movement driven by pneumatic pressure. Its telescopic rod end connects to a moving plate. Its function is to provide vertical thrust or pull, thereby changing the height of the moving plate and thus affecting the front height of the U-shaped support frame. Besides cylinders, hydraulic cylinders, electric push rods, or screw-lifting mechanisms can also be used as alternatives to achieve similar telescopic functions. A first synchronous motor is a motor capable of precisely controlling speed and position. Its output end is connected to a first screw, on which a first moving block is helically fitted. The first synchronous motor drives the first screw to rotate, causing the first moving block to move axially along the screw. This movement can change the height or position of the rear end of the U-shaped support frame. Besides synchronous motors, stepper motors, servo motors, or DC geared motors can also be used in conjunction with appropriate transmission mechanisms (such as rack and pinion, chains, etc.) to achieve precise linear movement. "Achieving a front-to-back upward tilt" refers to the overall posture of the U-shaped support frame, where its front end (broiler feed end) is relatively low, while its rear end (broiler discharge end or processing end) is relatively high, forming an upward slope. This tilting arrangement can utilize gravity to assist the conveying of broilers on the roller conveyor belt, or facilitate the flow of liquids generated during processing (such as wastewater and blood) towards the front or a specific direction, thereby improving cleaning efficiency and reducing pollution.

[0066] The solution of this application achieves precise tilting of the U-shaped support frame through coordinated control of a multi-section telescopic cylinder and a first synchronous motor. Specifically, the front end of the U-shaped support frame is rotatably hinged to a movable plate via a first support block, and the height of the movable plate is adjusted by the end of the telescopic rod of the multi-section telescopic cylinder located at the rear end of the upper surface of the support frame. Simultaneously, the rear end of the U-shaped support frame is connected via a first movable block, which is helically fitted onto a first screw driven by the first synchronous motor. When it is necessary to tilt the U-shaped support frame upwards from front to back, the multi-section telescopic cylinder can extend, raising the movable plate and thus raising the front end of the U-shaped support frame; simultaneously, the first synchronous motor drives the first screw, causing the first movable block to move backwards or upwards, thereby raising the rear end of the U-shaped support frame. By precisely coordinating the extension and retraction of the multi-section telescopic cylinder and the movement of the first synchronous motor, the front end of the U-shaped support frame can be relatively low, while the rear end is relatively high, forming a stable upward tilt angle. This structural combination allows the U-shaped support frame to not only be raised and lowered as a whole, but also to tilt to different degrees, thus adapting to the posture adjustment needs during broiler processing.

[0067] As a specific implementation method, when it is necessary to adjust the U-shaped support frame to an upward tilt from front to back, the multi-section telescopic cylinder can be activated first, extending its telescopic rod to a certain length, thereby raising the front end of the U-shaped support frame connected to the moving plate. Simultaneously, or after the multi-section telescopic cylinder extends, the first synchronous motor is activated, driving the first screw to rotate, causing the first moving block, which is helically sleeved on the first screw, to move rearward, thereby raising the rear end of the U-shaped support frame. By precisely controlling the extension and retraction stroke of the multi-section telescopic cylinder and the rotation angle of the first synchronous motor, the front end of the U-shaped support frame can be kept at a lower position, while the rear end is raised to a higher position, thus forming a preset upward tilt angle. For example, the height difference between the front and rear ends of the U-shaped support frame can be set to ensure that the broiler chickens can move smoothly backward on the roller conveyor belt, while facilitating the collection or discharge of liquid generated during processing at the front end.

[0068] Through the above technical solution, the U-shaped support frame can be tilted from front to back and upward according to actual needs. This adjustable tilt makes the conveying of broilers on the roller conveyor belt smoother, utilizing gravity to assist the movement of the broilers and improving conveying efficiency. At the same time, the tilt also helps wastewater, blood, and other liquids generated during processing to flow in a specific direction, facilitating centralized collection and discharge. This effectively improves hygiene conditions and cleaning efficiency during broiler processing, solves the need for U-shaped support frame posture adjustment during broiler processing, and enhances the adaptability and practicality of the equipment.

[0069] In some of the embodiments described above in this application, the broiler elevator generates wastewater, blood, and tissue debris during the broiler evisceration and internal lung cleaning processes. Without an effective collection and discharge mechanism, these pollutants may drip directly, causing environmental pollution, affecting equipment hygiene, and may even splash back onto the broilers being processed, reducing product quality.

[0070] In some other embodiments, this application proposes a broiler elevator, in which a wastewater tank 9 with an open upper surface is provided in front of the support frame 1. The wastewater tank 9 is located at the feed inlet of the U-shaped support frame 2. A drain pipe 91 is connected to the side of the wastewater tank 9. A strip-shaped opening 92 is provided at the front end of each of the two vertical plates of the U-shaped support frame 2. A first motor (not shown) is provided in the strip-shaped opening 92. A second screw 93 is connected to the output end of the first motor. A second moving block 94 is spirally sleeved on the second screw 93. A U-shaped water guide plate 95 is connected to the inner side of the second moving block 94. The U-shaped water guide plate 95 extends to the water inlet of the wastewater tank 9.

[0071] The wastewater tank is a container used to collect and temporarily store wastewater. Its open upper surface facilitates the inflow of wastewater and subsequent cleaning and maintenance. The wastewater tank can be made of corrosion-resistant materials such as stainless steel, high-density polyethylene (HDPE), or fiberglass to accommodate wastewater environments containing blood, grease, and detergents. Its size and capacity can be designed according to the broiler processing volume and wastewater generation rate to ensure effective collection of wastewater generated during treatment. The drain pipe is used to discharge the wastewater collected in the wastewater tank to an external treatment system. The drain pipe can be made of flexible or rigid materials, such as PVC pipe, stainless steel pipe, or rubber hose, and its inner diameter should be large enough to ensure smooth drainage and avoid blockages. The drain pipe is typically connected to a wastewater treatment system or centralized discharge pipeline to meet environmental protection requirements. The slotted opening is a narrow groove opened at the front end of the two vertical plates of the U-shaped support frame. This opening design allows for linear movement or adjustment of internal components while maintaining structural strength. The strip-shaped opening can be formed on the metal plate of the U-shaped support frame using processes such as milling, laser cutting, or stamping. Its length and width need to be precisely designed according to the stroke and dimensions of the internal moving parts. The first motor is a power device that converts electrical energy into mechanical energy to drive the rotation of the second screw. The first motor can be a stepper motor, servo motor, or DC geared motor, the specific choice depending on the required control precision, torque, and operating speed. For example, a stepper motor can provide precise position control, while a DC geared motor has higher torque output. The second screw is a rod-shaped component with helical grooves that converts the rotational motion of the first motor into the linear reciprocating motion of the second moving block through a threaded engagement with the second moving block. The second screw can be a trapezoidal screw, ball screw, or ACME screw, where ball screws offer higher transmission efficiency and positioning accuracy, while trapezoidal screws are less expensive and have better self-locking properties. The second moving block is a component that threadedly engages with the second screw and moves along its axial direction when the second screw rotates. The second moving block is typically made of wear-resistant materials, such as engineering plastics (e.g., POM, UHMW-PE) or metal alloys (e.g., brass, bronze), to ensure smooth and low-friction movement. Its internal threads match the thread type of the second screw. The U-shaped guide vane is a plate-like structure with a U-shaped cross-section, its main function being to collect and guide wastewater flow to the wastewater tank. The U-shaped guide vane can be made of stainless steel, food-grade plastic, or corrosion-resistant alloys, and its U-shaped cross-section design helps to concentrate the water flow and prevent splashing. Its extension to the wastewater tank inlet ensures effective wastewater introduction.

[0072] The solution proposed in this application is achieved as follows: During broiler processing in a broiler elevator, the cutting and cleaning components on the U-shaped support frame generate wastewater, blood, and other contaminants. To effectively collect these contaminants, a wastewater tank with an open upper surface is installed in front of the support frame. This wastewater tank is positioned at the feed inlet of the U-shaped support frame, below the area where contaminants may be generated and drip. A drain pipe connected to the side of the wastewater tank is responsible for discharging the collected wastewater to prevent the tank from overflowing. To further optimize the wastewater collection efficiency, strip-shaped openings are provided at the front ends of the two vertical plates of the U-shaped support frame. A first motor is installed within these strip-shaped openings, with its output end connected to a second screw. A second moving block is spirally fitted onto the second screw, and a U-shaped water guide plate is connected to the inner side of the second moving block. When the first motor drives the second screw to rotate, the second moving block moves linearly along the second screw, thereby causing the U-shaped water guide plate to move within the strip-shaped openings. The U-shaped structure of the U-shaped water guide plate effectively collects wastewater dripping from the U-shaped support frame and guides it to the inlet of the wastewater tank. Through this linkage mechanism, the U-shaped water guide plate can adjust its position according to actual needs, ensuring that during the broiler processing, regardless of the tilt or movement of the U-shaped support frame, wastewater can be captured to the maximum extent and accurately guided into the wastewater tank, thereby avoiding wastewater overflow and pollution.

[0073] The following is a concrete example: A wastewater tank made of food-grade stainless steel can be installed in front of the support frame, with its upper surface open for easy observation and cleaning. This wastewater tank is connected to a DN50 PVC drain pipe via a flange, which connects to the workshop's wastewater treatment system. Each of the two vertical plates of the U-shaped support frame has a 300mm long and 20mm wide strip opening at its front end. A 24V DC geared motor is installed in each strip opening as the first motor, and its output shaft is connected via a coupling to a 12mm diameter, 4mm lead trapezoidal screw as the second screw. A second movable block made of POM material is threaded onto the second screw. A U-shaped water guide plate made of 304 stainless steel is fixed to the inner side of the second movable block with screws. The width of this U-shaped water guide plate is slightly smaller than the inner width of the U-shaped support frame, with its U-shaped opening facing upwards and extending forward, allowing its front end to extend above the inlet of the wastewater tank. When the broiler elevator is working, the first motor can drive the second screw to rotate according to the preset program or sensor feedback, so that the U-shaped water guide plate moves back and forth in the strip opening to adapt to the posture changes of the U-shaped support frame, ensuring that the wastewater is always effectively collected and introduced into the wastewater tank.

[0074] Through the above technical solution, wastewater, blood, and tissue debris generated during the broiler elevator's abdominal cutting and lung cleaning processes can be effectively collected by a wastewater tank in front of the support frame. The wastewater tank is located at the feed inlet of the U-shaped support frame, ensuring that contaminants are captured immediately. A first motor drives a second screw and a second moving block, allowing the U-shaped guide plate to move precisely within the strip-shaped openings at the front ends of the two vertical plates of the U-shaped support frame, extending to the inlet of the wastewater tank. The U-shaped structure of the guide plate efficiently collects and guides wastewater, preventing it from dripping or splashing onto the outside of the equipment or onto the processed broilers. This not only significantly improves the hygiene of the working environment and reduces the risk of cross-contamination, but also ensures timely discharge of wastewater through the drain pipe, preventing overflow of the wastewater tank, guaranteeing the continuous and stable operation of the equipment, and improving the cleanliness of the broiler processing process and product quality.

[0075] In some of the embodiments described above in this application, a broiler elevator is proposed, in which a roller conveyor belt for conveying broilers is provided at the upper end of the U-shaped support frame. However, when the broilers are conveyed by the roller conveyor belt, due to the irregular shape of the broilers themselves or the shaking during the conveying process, the broilers may become unstable on the conveyor belt, or even deviate or fall off, affecting the accuracy and efficiency of subsequent processing operations such as ventilation and lung suction.

[0076] Please continue reading. Figures 1 to 6 As shown, this application further proposes that a fixing block 21 is provided at the middle of the outer side of each of the two vertical plates of the U-shaped support frame 2, and a second support block 22 is provided on the upper surface of the fixing block 21. The second support block 22 is perpendicular to the fixing block 21, and a second support rod 23 is provided between the second support blocks 22 at the left and right ends. A limiting rod 24 for limiting the broiler chicken is provided at both the left and right ends of the second support rod 23.

[0077] The first component, the fixing block, is a structural component providing the mounting base. It is typically securely installed on the middle of the outer sides of the two vertical plates of the U-shaped support frame through welding, bolting, or other methods. Its function is to provide a stable support point for the subsequent limiting structure, ensuring the accurate and secure installation of the limiting components. The second support block is a structural component installed on the upper surface of the fixing block, perpendicular to it. It can be L-shaped, T-shaped, or rectangular, and is connected to the fixing block through bolts, riveting, or welding. The main function of the second support block is to provide a raised and stable mounting plane for the second support rod, allowing the limiting rod to be at a suitable height for effective chicken restraint. The second support rod is a rod-shaped structure connecting the left and right second support blocks. It can be a solid rod, hollow tube, profile, etc., and the material can be stainless steel, aluminum alloy, or other materials with certain strength and corrosion resistance. It spans across the U-shaped support frame, providing lateral installation and support for the limiting rod. Its function is to form a lateral limiting barrier and serve as the mounting carrier for the limiting rod. The limiting rods are rod-shaped structures located at both ends of the second support rod, used to limit the movement of the broilers. The limiting rods can be straight, curved, or have an arc shape, and their surfaces can be treated with anti-slip materials or covered with soft materials to prevent damage to the broilers. The function of the limiting rods is to create a restricted area above the roller conveyor belt, based on the size of the broilers and the conveying requirements, preventing the broilers from swaying left and right or deviating from their predetermined position during transport, ensuring stable transport of the broilers on the roller conveyor belt.

[0078] The solution proposed in this application involves setting a fixing block at the middle of the outer side of the two vertical plates of a U-shaped support frame, and vertically mounting a second support block on the fixing block, which in turn connects to a second support rod. A limiting rod is then installed on the second support rod, thereby constructing a stable limiting structure above the roller conveyor belt. When broilers are conveyed by the roller conveyor belt, the limiting rod effectively restricts the lateral movement range of the broilers, preventing them from deviating from their position or falling due to shaking, tilting, or lifting operations during the conveying process. This structure ensures the stability and positioning accuracy of the broilers throughout the entire conveying and processing process, providing reliable broiler positioning assurance for subsequent ventilation operations for cutting parts and lung suction operations for cleaning parts.

[0079] In one specific implementation, rectangular steel fixing blocks can be securely installed by welding on the middle of the outer sides of the two vertical plates of the U-shaped support frame. L-shaped aluminum alloy second support blocks are bolted to the upper surface of these fixing blocks, ensuring their vertical portions face upwards. A stainless steel round tube serves as a second support rod, connected to the top of the second support blocks on both sides via clamps or bolts. Straight rod-shaped limiting rods with rubber sleeves can be installed at both ends of the second support rod. The length and spacing of these limiting rods can be adjusted according to the average size of the broilers to ensure that the broilers are effectively restrained on the roller conveyor belt without hindering their forward movement.

[0080] The above technical solution effectively solves the problems of unstable position, deviation, or falling of broilers on the roller conveyor belt during broiler elevator transport. This limiting structure ensures the stability and positioning accuracy of the broilers during transport, significantly improving the accuracy and efficiency of subsequent processing operations such as evisceration and lung suction, thereby enhancing the automation level and product quality of the entire broiler processing process.

[0081] In some other embodiments, this application proposes a broiler lifting machine, which includes a support frame. Guide rails are provided at both ends of the upper surface of the support frame. First support rods are provided at the rear ends of both sides of the upper surface of the support frame. First strip-shaped grooves are formed on the inner sides of the first support rods. A first synchronous motor is disposed within each of the first strip-shaped grooves. A first screw is connected to the output end of the first synchronous motor. A first moving block is spirally sleeved on the first screw. A U-shaped support frame is connected between the first moving blocks at both ends. A moving plate is slidably sleeved on the guide rails. Multiple telescopic cylinders are provided at the rear end of the middle section of the upper surface of the support frame. The ends of the telescopic rods of the multiple telescopic cylinders are connected to the moving plate. First support blocks are provided at both ends of the upper surface of the moving plate. The first support blocks are rotatably hinged to the front ends of the two vertical plates of the U-shaped support frame. A roller conveyor belt for conveying broilers is provided at the upper end of the U-shaped support frame. A cutting component for opening the abdomen of the broilers during transport is provided at the front end of the U-shaped support frame. A cleaning component for sucking the lungs inside the broilers is provided at the rear end of the U-shaped support frame.

[0082] In some of the embodiments described above in this application, a cutting component for opening the abdomen of broilers during transport is proposed on the broiler elevator. However, in actual operation, how to accurately control the movement of the cutting component to adapt to the individual differences of different broilers and ensure the efficiency and consistency of the opening operation is a technical problem that needs to be solved.

[0083] Please continue reading. Figures 1 to 7As shown, this application further proposes that the aforementioned cutting component 4 includes a cutting blade 41, and that the front ends of the outer sides of the two vertical plates of the U-shaped support frame 2 are each provided with a second strip-shaped groove 42. A second synchronous motor (not shown) is disposed in the second strip-shaped groove 42, and the output end of the second synchronous motor is connected to a third screw (not shown). A third moving block (not shown) is spirally sleeved on the third screw, and a first L-shaped support block 43 is disposed on the outer side of the third moving block. A first telescopic cylinder 44 is disposed on the upper surface of the first L-shaped support block 43, and a first lifting plate 4 is disposed at the end of the telescopic rod of the first telescopic cylinder 44. 5. The lower surface of the first lifting plate 45 is provided with a T-shaped pushing rod 46 for pushing broiler chickens. The front ends of the outer sides of the two vertical plates of the U-shaped support frame 2 are fixed with second L-shaped support blocks 47 by bolts. The first L-shaped support block 43 and the second L-shaped support block 47 are arranged in front and behind. The upper surface of the second L-shaped support block 47 is provided with a third support rod 48. The third support rod 48 is provided with a strip-shaped limiting port 49. The lifting screw 40 is fixed between the strip-shaped limiting ports 49 at the left and right ends by nuts. The middle part of the lifting screw 40 is provided with a knife holder 6. The lower surface of the knife holder 6 is provided with the cutting blade 41.

[0084] The cutting blade is the component that directly performs the abdominal opening operation on the broiler chicken. It can be a sharp metal blade, such as a stainless steel blade, with its edges precisely ground to ensure a smooth and efficient cut; or it can be a ceramic blade, which has good wear resistance and corrosion resistance. The second strip-shaped groove is located at the front end of the outer side of the two vertical plates of the U-shaped support frame. It is used to accommodate and guide the movement of the second synchronous motor and related components. It can be formed on the U-shaped support frame by milling or casting, and its inner surface can be polished to reduce friction. The second synchronous motor provides power to drive the cutting component to move horizontally. It can be a stepper motor or a servo motor. By precisely controlling its rotation angle and speed, it achieves precise drive of the third screw. The third screw converts the rotational motion of the second synchronous motor into the linear motion of the third moving block. It can be a ball screw or trapezoidal screw to ensure transmission efficiency and positioning accuracy. The third moving block carries the first L-shaped support block and moves linearly on the third screw. It can be a metal block with threaded holes, and its material can be stainless steel or aluminum alloy to ensure strength and lightweight. The first L-shaped support block supports the first telescopic cylinder and the first lifting plate. It can be made of L-shaped metal profile and fixed to the third moving block by welding or bolting. The first telescopic cylinder provides power to drive the first lifting plate to move vertically. It can be a single-acting or double-acting cylinder, and the telescopic rod can be precisely extended and retracted by controlling the air pressure. The first lifting plate carries the T-shaped push rod and moves up and down with the extension and retraction of the first telescopic cylinder. It can be a flat metal plate with mounting holes on its lower surface for fixing the T-shaped push rod. The T-shaped push rod is used to push the broiler chicken before or during cutting to place it in the optimal cutting position. It can be a T-shaped rod with an arc or obtuse angle at the end to avoid damaging the broiler chicken. The second L-shaped support block fixes the third support rod. It can be made of L-shaped metal profile and fixed to the front end of the outer side of the two vertical plates of the U-shaped support frame by bolting. The third support rod supports the lifting screw and can be a cylindrical or square metal rod with a strip-shaped limiting opening on its upper surface. The strip-shaped limiting port, located on the third support rod, is used to limit the horizontal position of the lifting screw. It can be formed by milling or wire cutting, and its length and width should match the diameter of the lifting screw. The nut is used to fix the lifting screw and allow for vertical adjustment. A standard nut can be used, and it is fixed by threaded engagement with the lifting screw. The lifting screw is used to adjust the vertical height of the tool holder and cutting blade. It can be a threaded rod, and its height is adjusted by rotating the nut or by its own rotation. The tool holder is used to fix the cutting blade and can be a metal block with a slot or mounting hole on its lower surface for mounting the cutting blade.

[0085] This application's solution achieves precise control of the broiler's abdominal cutting operation through a sophisticated mechanical structure and drive system. When the broiler is transported to the cutting area via a roller conveyor belt within a U-shaped support frame, a second synchronous motor receives a control signal and drives a third screw connected to its output end to rotate. The rotation of the third screw causes a third moving block, spirally mounted on it, to move horizontally along a second strip-shaped groove. Since the first L-shaped support block is fixed to the outer side of the third moving block, the first L-shaped support block, the first telescopic cylinder mounted on it, and the first lifting plate and T-shaped push rod connected to the end of the telescopic rod of the first telescopic cylinder will move horizontally accordingly. This allows the T-shaped push rod to be precisely moved to a preset pushing position according to the size or position of the broiler. After horizontal positioning is completed, the telescopic rod of the first telescopic cylinder extends, causing the first lifting plate to descend, so that the T-shaped push rod contacts and pushes the broiler, stabilizing it in the optimal cutting position. At the same time, the cutting blade is fixed to the lower surface of the lifting screw via a blade holder. The two ends of the lifting screw are fixed between the strip-shaped limiting openings of the third support rod by nuts. The third support rod is then fixed to the front end of the outer side of the two vertical plates of the U-shaped support frame by the second L-shaped support block. By rotating the lifting screw, the vertical height of the cutting blade can be precisely adjusted to adapt to the different blotting depth requirements of broilers. After the broiler is stabilized and positioned by the T-shaped push rod, the cutting blade performs the blotting operation at the preset height. The entire process, through the coordinated action of the second synchronous motor and the first telescopic cylinder, as well as the fine adjustment of the lifting screw, ensures the accuracy of the cutting position and the consistency of the cutting depth, effectively solving the problem of inaccurate cutting caused by individual differences in broiler blotting operations.

[0086] In one specific implementation, the cutting blade can be made of high-strength stainless steel, with its cutting edge finely ground to ensure sharpness and durability. The second synchronous motor can be a high-precision stepper motor, which sends pulse signals through a controller to achieve precise angle control of the third screw. The third screw can be a ball screw to provide high-efficiency and low-friction linear motion. The first telescopic cylinder can be a small pneumatic actuator, controlled by air pressure to extend and retract, thereby driving the first lifting plate and the T-shaped push rod to move vertically. The contact surface of the T-shaped push rod can be made of food-grade polymer material and designed with an arc shape to avoid damage when pushing the broiler chicken. The lifting screw can be a precision threaded rod, which can be rotated manually or electrically to adjust the vertical height of the blade holder and the cutting blade. The blade holder can be designed with a modular structure for easy installation and replacement of the cutting blade.

[0087] Through the above technical solution, the broiler lifting machine of this application can achieve precise control of the broiler venting and cutting operation. The cooperation of the second synchronous motor, the third screw, and the third moving block enables the cutting piece to be precisely adjusted horizontally according to the actual position of the broiler, ensuring that the cutting point is always located at the target position. The T-shaped push rod driven by the first telescopic cylinder can stably and accurately push the broiler to the preset cutting area before cutting, avoiding shaking or positional deviation of the broiler during the conveying process. At the same time, the setting of the lifting screw and the blade holder allows for precise adjustment of the vertical height of the cutting blade, thereby adapting to the venting depth requirements of broilers of different sizes, ensuring the consistency of cutting depth and the standardization of venting effect. This adjustable and positionable cutting mechanism significantly improves the accuracy, efficiency, and consistency of broiler venting operation, effectively solving the problems of inaccurate cutting and low efficiency caused by individual differences in broilers in traditional cutting methods, and improving the automation level and product quality of broiler processing.

[0088] In some other embodiments, this application proposes a broiler elevator, in which a cleaning component for performing internal lung suction on the broiler is provided at the rear end of its U-shaped support frame. However, in actual operation, how to ensure that the cleaning component can accurately and efficiently perform internal lung suction on broilers of different sizes and postures, and achieve accurate alignment and depth control of the suction head, is a technical problem that needs to be solved.

[0089] Please continue reading. Figures 1 to 6 , Figure 8 As shown, this application further proposes the aforementioned broiler lifting machine, wherein the cleaning component 5 includes a poultry lung suction machine 51. The cleaning component 5 includes the poultry lung suction machine 51. A third L-shaped support block 52 is provided at the rear end of each of the two vertical plates of the U-shaped support frame 2. A second telescopic cylinder 53 is provided on the upper surface of the third L-shaped support block 52. A second lifting plate 54 is provided at the end of the telescopic rod of the second telescopic cylinder 53. A T-shaped pressing rod 55 is provided in the middle of the lower surface of the second lifting plate 54. An extension block 56 extends from the middle of the rear surface of the second lifting plate 54. A third telescopic cylinder 57 is embedded in the extension block 56. A lifting block 58 is provided at the end of the telescopic rod of the third telescopic cylinder 57. A lung suction head 59 is provided on the lifting block 58. The poultry lung suction machine 51 is provided at the right rear end of the upper surface of the support frame 1. The poultry lung suction machine 51 is connected to the lung suction head 59 via a pipe 50.

[0090] A poultry lung suction machine is a device specifically designed to remove lung contents and other internal organ residues from poultry. Its working principle typically utilizes vacuum negative pressure to draw the target material in through a suction head. Poultry lung suction machines can be driven by an electric vacuum pump or a pneumatic vacuum generator. The rear ends of the outer sides of the two vertical plates of the U-shaped support frame are each equipped with a third L-shaped support block. This third L-shaped support block is a structural component used to fix and support other parts. Its L-shaped design provides two mutually perpendicular mounting surfaces, facilitating component installation and positioning. The third L-shaped support block can be fixed to the U-shaped support frame by welding, bolting, or riveting. A second telescopic cylinder is installed on the upper surface of the third L-shaped support block. This second telescopic cylinder is a linear actuator that uses compressed air to drive the piston rod to extend and retract, thereby achieving vertical lifting and lowering movement. Its function is to provide vertical adjustment capability for the lung suction mechanism. The second telescopic cylinder can be a single-acting cylinder, a double-acting cylinder, or a cylinder with a buffer device. The second telescopic cylinder has a second lifting plate at its telescopic rod end. This second lifting plate is a platform connecting the second telescopic cylinder and subsequent components, moving up and down with the cylinder's extension and retraction, and supporting the rest of the suction mechanism. The second lifting plate can be made of sheet metal (such as stainless steel or aluminum alloy) and connected to the telescopic rod by bolts or welding. A T-shaped pressing rod is located in the center of the lower surface of the second lifting plate. This T-shaped pressing rod is used to position or slightly press the broiler during suction operation to assist in the accurate entry and operation of the suction head. Its T-shaped structure provides a certain contact area and stability. The T-shaped pressing rod can be made of metal and fixed to the lower surface of the second lifting plate by bolts or welding. An extension block extends from the center of the rear surface of the second lifting plate. This extension block is a rearward extension of the second lifting plate, used to install the third telescopic cylinder, providing additional installation space and support. The extension block can be integrally formed with the second lifting plate or connected by welding or bolts. A third telescopic cylinder is embedded in the extension block. This third telescopic cylinder is another linear actuator used to provide horizontal (forward and backward) adjustment capability for the suction head. Its embedding in the extension block saves space and provides a more compact structure. The third telescopic cylinder can be a small cylinder, a thin cylinder, or an electric push rod. A lifting block is provided at the end of the telescopic rod of the third telescopic cylinder. This lifting block is a component connecting the third telescopic cylinder and the suction head, moving back and forth with the cylinder's extension and retraction, directly supporting the suction head. The lifting block can be made of engineering plastic or metal and connected to the telescopic rod by bolts or clips. The suction head is mounted on the lifting block. This suction head is the component that directly contacts the broiler and performs the suction operation. Its shape and size are usually designed according to the broiler's anatomy to ensure efficient suction. The suction head can be made of corrosion-resistant materials (such as stainless steel or food-grade plastic) and has an appropriate suction port shape and size. The poultry suction machine is located at the right rear end of the upper surface of the support frame. The poultry suction machine body is fixed in a specific position on the support frame for easy connection to the suction head via a pipe.Poultry lung suction machines can be fixed with bolts or mounted on brackets. The machine is connected to the suction head via tubing, which transmits suction power. The tubing can be made of pressure-resistant, corrosion-resistant flexible or rigid tubing, such as PVC or silicone tubing, and connected using connectors.

[0091] This application's solution automates and refines the lung-sucking operation for broilers by installing a precisely adjustable cleaning component at the rear end of the U-shaped support frame of the broiler elevator. When the broiler is conveyed by a roller conveyor to the rear end of the U-shaped support frame for lung-sucking, the poultry lung-sucking machine, fixed to the support frame, is connected to the lung-sucking head via a pipe. The lung-sucking head is mounted on a lifting block, which is driven by a third telescopic cylinder embedded in an extension block, enabling horizontal forward and backward movement. The extension block is connected to a second lifting plate, which is driven by a second telescopic cylinder mounted on a third L-shaped support block, enabling vertical up and down movement. Through the coordinated action of the second and third telescopic cylinders, the lung-sucking head can be precisely adjusted vertically and horizontally according to the broiler's actual position and body shape, ensuring that the lung-sucking head accurately enters the broiler's body cavity and aligns with the lungs. A T-shaped pressure bar on the lower surface of the second lifting plate can assist in positioning or slightly press the broiler before the lung-sucking head enters, further improving the accuracy of lung-sucking. Once the suction head is in place, the poultry lung suction machine starts, generating negative pressure to suck out the lungs and other residues from the broiler chicken through the suction head and transport them through pipes to the collection device. This dual-axis (vertical and horizontal) adjustable lung suction mechanism makes the entire lung suction process more precise and efficient, effectively addressing the challenges posed by individual differences among broilers.

[0092] The following is a specific example: a poultry lung suction machine can use an industrial-grade vacuum pump as its power source, generating negative pressure through a vacuum generator, and is equipped with a filter and a collection tank. The third L-shaped support block can be made of 5mm thick stainless steel sheet bent into an L-shape and fixed to the rear end of the two vertical plates of the U-shaped support frame with M8 bolts. The second telescopic cylinder can be a double-acting cylinder with a stroke of 100mm, such as the SMC CDQ2B40-100D cylinder, whose air supply is controlled by a solenoid valve. The second lifting plate can be made of 200mm x 150mm x 3mm aluminum alloy sheet, connected to the end of the telescopic rod of the second telescopic cylinder with bolts. The T-shaped pressing rod can be a 15mm diameter, 100mm long stainless steel round rod, with a 50mm wide flat T-shaped head welded to its end, and fixed to the center of the lower surface of the second lifting plate with a threaded connection. The extension block can be integrally formed with the second lifting plate, or it can be welded onto an aluminum alloy block measuring 80mm x 50mm x 3mm. The third telescopic cylinder can be a thin cylinder with a stroke of 50mm, such as a Festo DSNU-20-50-PA cylinder, embedded inside the extension block. The lifting block can be a food-grade polypropylene (PP) block measuring 60mm x 40mm x 20mm, connected to the end of the telescopic rod of the third telescopic cylinder via clips or bolts. The suction head can be made of stainless steel, designed with a funnel-shaped suction port with a diameter of 30mm and chamfered to facilitate entry into the broiler's body cavity. The tubing can be a food-grade silicone hose with an inner diameter of 15mm, connected to the poultry suction machine and suction head via quick connectors.

[0093] The above technical solution incorporates adjustable cleaning components, including a poultry lung suction machine and a precision positioning mechanism comprised of a second telescopic cylinder, a third telescopic cylinder, a second lifting plate, a lifting block, and a lung suction head. This allows for precise adjustment of the lung suction head in both vertical and horizontal directions. This enables the lung suction head to accurately enter the broiler's body cavity and align with the lungs according to the size and posture of different broilers, ensuring thoroughness and efficiency in the lung suction operation and significantly improving the quality and automation level of internal cleaning. Compared to solutions that only provide fixed cleaning components, this solution effectively solves the problems of inaccurate lung suction head alignment and incomplete lung suction, improving the hygiene standards and production efficiency of broiler processing.

[0094] In some of the aforementioned embodiments, the broiler elevator transports broilers via a roller conveyor belt and performs operations such as abdominal dissection and lung suction. However, during broiler processing, contaminants such as blood, meat scraps, and feathers are inevitably generated, which may adhere to the broiler's surface and the roller conveyor belt. If not removed promptly and effectively, these residues will not only affect the hygienic quality of the broilers but may also lead to equipment contamination, increase the risk of cross-infection, and potentially affect the normal operation and maintenance of the equipment.

[0095] Please continue reading. Figures 1 to 5 As shown, this application further proposes to provide multiple flushing pipes 7 at equal intervals between the two vertical plates of the U-shaped support frame 2, and the flushing pipes 7 are located below the roller conveyor belt 3. Multiple downward-sloping high-pressure flushing heads (not shown) are provided at equal intervals on the flushing pipes 7, and water supply pipes 71 for supplying water to the flushing pipes 7 are provided at equal intervals on the lower surface of the U-shaped support frame 2.

[0096] The rinsing pipe is used to transport the cleaning liquid. It can be made of corrosion-resistant materials, such as stainless steel, PVC, or polyethylene, to suit the properties of the cleaning liquid. The arrangement of the rinsing pipes can be adjusted according to the width of the cleaning area and the required cleaning effect. For example, they can be arranged side-by-side or staggered to ensure uniform cleaning coverage. The roller conveyor belt is used to carry and transport the broilers. The rinsing pipe is located below the roller conveyor belt to clean the bottom of the broilers or the surface of the roller conveyor belt. The high-pressure rinsing head is a nozzle used to spray the cleaning liquid at high pressure. It can use various spray patterns, such as fan-shaped spray, cone-shaped spray, or straight spray, to meet different cleaning intensity and coverage requirements. The high-pressure rinsing head is tilted downwards so that the spray direction can effectively cover the bottom of the broilers or the surface of the roller conveyor belt, thereby achieving effective removal and rinsing of attached dirt. The water supply pipe is used to supply the cleaning liquid to the rinsing pipe. It can be connected to an external water source, a circulating water system, or a dedicated cleaning liquid storage tank to ensure a continuous supply of cleaning liquid. The diameter and material of the water supply pipe should be able to withstand the working pressure of the cleaning system and ensure sufficient flow.

[0097] This application's solution involves equidistantly arranged rinsing pipes between the two vertical plates of a U-shaped support frame, positioned below the roller conveyor belt. This allows for continuous cleaning of the broiler's bottom and the conveyor belt during transport. A water supply pipe delivers the cleaning fluid to the rinsing pipes, while multiple downward-sloping high-pressure rinsing heads, evenly spaced on the pipes, apply the cleaning fluid to the target area in a high-pressure jet. This arrangement ensures that the cleaning fluid evenly and comprehensively covers the broiler's bottom and the conveyor belt, effectively removing blood, meat scraps, feathers, and other contaminants generated during processing using the impact force of the high-pressure water flow. In this way, the cleanliness of the broiler's surface and the conveyor belt is significantly improved before it is transported to subsequent processing stations, effectively preventing the accumulation and spread of contaminants on the production line and providing a clean environment for subsequent processing.

[0098] The following is a concrete example: Three flushing pipes, spaced approximately 150 mm apart, can be installed between the two vertical plates of the U-shaped support frame. These flushing pipes can be made of DN20 stainless steel. Five high-pressure flushing heads, such as stainless steel fan-shaped nozzles, can be installed at equal intervals on each flushing pipe, with a spray angle set at 30 degrees and installed at a downward tilt of 45 degrees to ensure that the water jet effectively covers the entire width of the roller conveyor belt. The water supply pipe can be a DN25 food-grade PVC pipe, connected to a cleaning solution storage tank with a filter via a booster pump to ensure the pressure and cleanliness of the cleaning solution.

[0099] Through the above technical solution, while the broiler elevator transports and initially processes the broilers, it can simultaneously achieve real-time and efficient cleaning of the broiler's surface (especially the bottom) and the roller conveyor belt. The water jets from the high-pressure flushing heads powerfully wash away blood, meat scraps, feathers, and other residues generated during the broiler's evisceration and lung suction processes, effectively preventing the accumulation of these contaminants on the broiler's surface and the conveyor belt. This significantly reduces the risk of cross-contamination in subsequent processing stages, ensuring the hygienic quality of the broiler products. Simultaneously, continuous cleaning keeps the roller conveyor belt clean, reducing equipment malfunctions and maintenance needs caused by dirt accumulation, and improving the equipment's operating efficiency and service life.

[0100] In some embodiments described above in this application, the broiler elevator performs initial rinsing of the broilers using a rinsing pipe and a high-pressure rinsing head located below the roller conveyor belt. However, in actual operation, relying solely on rinsing from below may be insufficient to thoroughly clean the entire surface of the broiler, especially its upper and sides, potentially leaving residual dirt in some areas and affecting the final hygienic quality of the broilers.

[0101] Please refer to Jiangxi. Figures 1 to 6As shown, this application further proposes that a U-shaped water outlet pipe 8 is provided at the rear end between the two vertical plates of the U-shaped support frame 2, and multiple high-pressure water nozzles (not shown) are provided at equal intervals on the U-shaped water outlet pipe 8. The water nozzles of the high-pressure water nozzles are inclined downwards, and the U-shaped water outlet pipe 8 is connected to the water supply pipe 71.

[0102] The U-shaped water outlet pipe is a water conveying pipe with a U-shaped structure, whose main function is to carry and distribute water flow. This pipe can be made of various materials, such as corrosion-resistant materials like stainless steel, PVC, or PP, to adapt to humid environments and environments that may contain detergents. Its U-shaped design allows it to surround or partially surround the broiler chickens being treated, thus achieving multi-angle water flow coverage. The high-pressure spray head is a device that can spray water at high pressure for efficient rinsing and cleaning. Its nozzle is angled downwards, meaning the water flow is not sprayed vertically downwards, but at a certain angle. This helps the water flow better cover the sides and upper areas of the broiler chickens and uses the impact force of the water flow to remove dirt adhering to the chicken's surface. The high-pressure spray head can employ various spray patterns, such as fan-shaped spray, cone-shaped spray, or spot spray, to adapt to different cleaning intensities and coverage requirements. The connection between the U-shaped water outlet pipe and the water supply pipe refers to the U-shaped water outlet pipe being connected to the water supply pipe through a specific connection method to obtain the required water source. This type of connection can take various forms, such as threaded connection, flange connection, welding or quick coupling, to ensure the sealing and stability of the connection and prevent water leakage.

[0103] This application's solution constructs a complete broiler surface rinsing system by installing a U-shaped water outlet pipe at the rear end between the two vertical plates of a U-shaped support frame, and equidistantly installing multiple downward-sloping high-pressure water nozzles on it. The U-shaped water outlet pipe is connected to a water supply pipe. After the broiler passes through the cleaning components on the roller conveyor belt and moves to the rear end of the U-shaped support frame, the high-pressure water nozzles on the U-shaped water outlet pipe spray high-pressure water streams from above and to the sides of the broiler at an angle downwards. These high-pressure water streams effectively clean the broiler's back, chest, and sides, creating a pincer cleaning effect with the rinsing pipe and high-pressure rinsing heads located below the roller conveyor belt. The water supply pipe continuously provides water to the U-shaped water outlet pipe, ensuring a stable output of high-pressure water from the high-pressure nozzles. This design allows the broiler to receive high-pressure water rinsing from multiple directions and angles as it passes through the elevator, ensuring thorough removal of dirt from its surface and achieving a more comprehensive cleaning effect.

[0104] As a specific implementation, the U-shaped water outlet pipe can be made of food-grade stainless steel, and its inner diameter can be selected according to the required water flow and pressure, for example, a stainless steel pipe with an inner diameter of 25mm can be used. This U-shaped water outlet pipe is connected to the water supply pipe via clamps or threaded joints, ensuring a secure connection and easy disassembly and maintenance. The high-pressure water nozzles can be fan-shaped nozzles with adjustable spray angle and flow rate, for example, a spray angle of 30 to 60 degrees, with the nozzle tilted downwards at approximately 45 degrees. These nozzles are evenly distributed along the U-shaped water outlet pipe, for example, one every 100mm, to ensure uniform water coverage. When broilers pass through this area, the high-pressure water flow forms a dense "water curtain," thoroughly rinsing the broilers.

[0105] Through the above technical solution, the broiler elevator can achieve comprehensive and deep cleaning of the broiler's body surface after processing. The U-shaped water outlet pipe and the inclined downward high-pressure water nozzles installed on it, in conjunction with the original lower rinsing system, effectively solve the problem that relying solely on lower rinsing is insufficient to thoroughly clean the upper and side areas of the broiler. This results in a significant reduction in dirt residue on the broiler's body surface when it leaves the elevator, greatly improving the hygienic quality of the broiler and the safety of subsequent processing, meeting higher food hygiene standards.

[0106] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
