Description

Technical Field

[0001] This utility model relates to the field of poultry slaughtering equipment technology, and in particular to a device for reducing wing breakage and blood stasis in broiler chickens. Background Technology

[0002] In modern broiler slaughtering and processing, from the initial processing stage after receiving live poultry, broilers need to be manually or mechanically hung on a suspension chain for subsequent electric shock, slaughter, and defecation processes. This series of operations, especially hanging live chickens on hooks and subsequently immersing them in an electric shock pool for anesthesia, often cause unnecessary physical shock to the broilers.

[0003] Existing chicken-hanging devices often prioritize the convenience of hooks and the continuity of transport, but they do not adequately consider how to effectively buffer and absorb the impact forces generated at the moment of hanging the chicken and during the electric shock upon immersion in water. When broilers are hung or immersed at high speed in the water tank, the impact caused by their own weight and inertia often directly affects their fragile wings and leg joints, leading to broken wings, fractures, and even large areas of subcutaneous bruising. These injuries not only seriously affect the appearance and commercial value of the broiler products but also cause unnecessary economic losses. Traditional buffering mechanisms, if present, are mostly simple spring structures with limited buffering stroke and elastic response, making them unsuitable for coping with varying impact scenarios and resulting in less than ideal performance.

[0004] Therefore, this utility model proposes a device for reducing wing breakage and blood stasis in broiler chickens to address the shortcomings of existing technologies. Utility Model Content

[0005] In view of the existing technology, the existing hanging device for reducing wing breakage and blood stasis in broilers has a single or missing buffer structure in the hanging and water-immersion electric shock stages, which cannot effectively absorb the impact force and easily leads to broken wings, broken legs or subcutaneous blood stasis in broilers. The present invention aims to provide a hanging device for reducing wing breakage and blood stasis in broilers with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a hanging device for reducing wing breakage and blood stasis in broilers, comprising: a base plate with multiple casters connected to the bottom; a support tube with its lower end vertically fixed to the upper surface of the base plate; a sliding frame slidably sleeved on the outer periphery of the support tube; and a connecting plate slidably connected to the sliding frame.

[0007] Multiple double-stage buffer suspension units are fixedly connected to the lower surface of the connecting plate. Each double-stage buffer suspension unit includes a hook, a connecting post, a fixing plate, a pressing ring, a spring one, and a spring two connected in sequence.

[0008] The upper end of the hook is fixedly connected to the lower end of the connecting post. The upper end of the connecting post passes through the connecting plate and is fixedly connected to the center of the fixing piece. The second spring is sleeved on the outer periphery of the connecting post, with its two ends elastically abutting against the lower surface of the fixing piece and the upper surface of the connecting plate, respectively. The pressing ring is slidably sleeved on the lower part of the outer periphery of the fixing piece. The spring is sleeved on the outer periphery of the connecting post and located below the pressing ring, with its two ends elastically abutting against the lower surface of the pressing ring and the upper surface of the connecting plate, respectively. With this structure, when the fixing piece descends under gravity to its lower surface and abuts against and pushes the pressing ring, the first spring is compressed, thus working in conjunction with the second spring to form a double-stage buffer.

[0009] Preferably, the device further includes a lifting and locking mechanism, and the sliding frame is fixedly connected to the lifting and locking mechanism via a connecting rod. The lifting and locking mechanism slidably and lockably engages with the support tube to achieve precise adjustment and locking of the vertical height of the sliding frame.

[0010] Furthermore, the lifting and engaging mechanism includes a sliding frame, which is slidably sleeved around the support tube. The connecting rod is fixedly connected to a limiting block fixed inside the sliding frame, so that the lifting and lowering of the sliding frame can synchronously drive the lifting and lowering of the sliding frame.

[0011] In one specific implementation, the lifting and engaging mechanism further includes a pin rod, which is telescopically inserted through a through hole in the limiting block. The support tube has multiple pin holes along its length for engaging with the end of the pin rod, allowing for height locking and unlocking through the insertion and removal of the pin rod.

[0012] Furthermore, the lifting and engaging mechanism also includes a movable plate and a spring three for driving the extension and retraction of the pin rod. The movable plate is slidably disposed on the outer wall of the slide frame, and one end of the spring three abuts against the inner wall of the movable plate, while the other end abuts against the pin rod, providing an elastic force for the pin rod to automatically reset.

[0013] Preferably, the connecting plate is connected to the sliding frame via a concave block fixed to its upper surface. The inner wall of the concave block has a groove, and the sliding frame slides within the groove. This structure ensures that the connecting plate can slide stably left and right on the sliding frame.

[0014] Preferably, the device further includes an electric shock tank. The electric shock tank is detachably placed on the upper surface of the base plate and located directly below the double-stage buffer suspension unit, and is used to perform electric shock anesthesia on the broilers suspended on the hook in conjunction with the chicken hanging action.

[0015] Preferably, in order to improve the safety of the device during movement and use, the top of the support tube away from the base plate is wrapped with a rubber sleeve for cushioning and protection, which can effectively prevent accidental damage caused by bumps.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problem in the prior art where rigid collisions and impacts on broilers are caused by insufficient or no single buffer during the hooking, water-immersion, electric shock, and lifting processes, resulting in broken wings, broken legs, and subcutaneous hematoma. This is achieved by setting up a multi-stage series double-stage buffer suspension unit consisting of a hook, connecting column, fixing plate, pressing ring, spring one, and spring two. The result is that the rigid collisions and impacts on broilers are not effectively absorbed due to insufficient or no buffer during the hooking, water-immersion, electric shock, and lifting processes. This achieves the technical effect of significantly reducing broiler injuries and improving product quality.

[0017] 2. This utility model, by setting up a sliding frame, a connecting rod, and a lifting and engaging mechanism including a sliding frame, a limiting block, a movable piece, a pin rod, and a spring, achieves precise and convenient adjustment of the hanging height. It solves the problem that the height of the chicken hanging device in the prior art is fixed or the adjustment is complicated, making it difficult to adapt to the needs of different broiler chickens and different operation stages. It achieves the technical effects of flexible operation, strong adaptability, and improved production efficiency.

[0018] 3. This utility model achieves the lateral sliding of the suspension unit by using a concave block and a sliding groove to connect the plate on the sliding frame. This solves the problem in the prior art where the chicken hanging distance is fixed and inconvenient to adjust, which may lead to chickens colliding with each other or inconvenient operation. It achieves the technical effect of improving the adjustability of the chicken hanging distance and reducing friction between chickens. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] Example: like Figure 1 As shown, the hanging device for reducing wing breakage and blood stasis in broilers includes a base plate 13 and a support pipe 206 vertically fixed to the upper surface of the base plate 13. The base plate 13 serves as a stable base for the entire device, and multiple casters 15 are connected to the bottom for easy movement and transport. The support pipe 206 serves as the main support column of the device, providing vertical guidance and load-bearing for the upper movable parts.

[0023] To solve the above-mentioned technical problems, an innovative design for a hanging device for reducing wing breakage and blood stasis in broilers includes a two-stage buffer suspension unit and a connecting plate 6 and a sliding frame 1 that work together to form a suspension structure that can effectively absorb impact energy.

[0024] Please refer to Figure 1 , Figure 3 and Figure 4 The device includes a sliding frame 1, which is slidably fitted onto the outer periphery of a support tube 206 and can move up and down along the support tube 206. A concave block 4 is slidably connected to the sliding frame 1, and a connecting plate 6 is fixedly connected to the concave block 4. The connecting plate 6 is a support platform for installing multiple broiler hanging units. Specifically, a groove 5 is formed on the inner wall of the concave block 4, and the crossbeam portion of the sliding frame 1 is slidably fitted into the groove 5. In this way, the connecting plate 6 can slide left and right on the sliding frame 1, facilitating the adjustment of the hook spacing.

[0025] Multiple double-stage buffer suspension units are fixedly connected to the lower surface of the connecting plate 6. Each unit is used to suspend one broiler chicken and provide cushioning. The double-stage buffer suspension unit includes a hook 12, a connecting post 11, a fixing plate 10, a pressing ring 8, a spring 7, and a spring 9. The hook 12 is the component directly used to hook the broiler chicken, and its upper end is fixedly connected to the lower end of the connecting post 11. The upper end of the connecting post 11 passes through the reserved hole in the connecting plate 6 and is firmly fixed to the center position of the fixing plate 10, so that the force of the hook 12 is directly transmitted to the fixing plate 10.

[0026] Spring 2 9 is sleeved on the outer periphery of connecting post 11, with its two ends elastically abutting against the lower surface of fixing plate 10 and the upper surface of connecting plate 6, respectively. As the first-stage buffer mechanism, the main function of spring 2 9 is to absorb the impact energy through its own compression at the moment the broiler is hooked onto hook 12, thus avoiding immediate damage to the broiler.

[0027] The pressing ring 8 is slidably fitted onto the lower outer periphery of the fixing plate 10, forming an annular pressure cap structure. The spring 7 is fitted onto the outer periphery of the connecting post 11 and located below the pressing ring 8, with its two ends elastically abutting against the lower surface of the pressing ring 8 and the upper surface of the connecting plate 6, respectively. As a second-stage buffer mechanism, when the weight of the broiler continues to increase or the device descends and impacts the water surface, the lower surface of the fixing plate 10 abuts against and pushes the pressing ring 8, which in turn compresses the spring 7. This two-stage, series-connected elastic buffer structure can more effectively disperse and absorb impact forces, significantly reducing the risk of injury to the broiler at different stages of operation.

[0028] Based on the above embodiments, the device further includes a lifting and locking mechanism 2, and the sliding frame 1 is fixedly connected to the lifting and locking mechanism 2 via a connecting rod 3. The lifting and locking mechanism 2 is slidably and lockably engaged with the support tube 206, enabling precise adjustment of the vertical height of the sliding frame 1 to accommodate broilers of different sizes or electric shock tanks 14 of different depths.

[0029] As a further embodiment, the lifting and engaging mechanism 2 includes a sliding frame 208, which is slidably sleeved on the periphery of the support tube 206. The connecting rod 3 is fixedly connected to the limiting block 201 fixed inside the sliding frame 208. By sliding the sliding frame 208 up and down on the support tube 206, the overall height of the sliding frame 1 is adjusted.

[0030] In another preferred embodiment, the lifting and locking mechanism 2 further includes a pin 204, which is telescopically inserted through a through hole 202 in the limiting block 201. The support tube 206 has multiple pin holes 207 along its length for engaging with the ends of the pin 204. By inserting the pin 204 into the pin holes 207 at different heights, the sliding frame 1 can be reliably locked at a selected height.

[0031] In a more specific embodiment, the lifting and engaging mechanism 2 further includes a movable piece 203 and a spring 205 for driving the extension and retraction of the pin 204. The movable piece 203 is slidably disposed on the outer wall of the slide frame 208. One end of the spring 205 abuts against the inner wall of the movable piece 203, and the other end abuts against the pin 204, providing an outward restoring force to the pin 204, ensuring that the pin 204 automatically pops out and locks its height when not compressed.

[0032] As another preferred embodiment, in order to prevent the top end of the support tube 206 from bumping and potentially damaging the chicken on the device during the movement or height adjustment of the device, the top end of the support tube 206 away from the base plate 13 is wrapped with a rubber sleeve 209 for cushioning protection.

[0033] As an additional preferred configuration, the device also includes an electric shock tank 14, which is detachably placed on the upper surface of the base plate 13 and located in the working area directly below the double-stage buffer suspension unit. The electric shock tank 14 is used to anesthetize broilers suspended on the hook 12 by electric shock during specific operational procedures.

[0034] Working principle: To avoid rigid collisions, the chickens are hung on the hook 12. The hook 12 drives the connecting column 11 to compress the spring 9 connecting the fixing plate 10 and the connecting plate 6 below through the fixing plate 10, thereby mitigating the phenomenon of broken wings and legs caused by rigid collisions. When multiple chickens hanging on the hook 12 are immersed in the electric shock pool 14 below by adjusting the up and down position of the sliding frame 1 through the lifting and locking mechanism 2, the hook 12 is buffered upward by the stretching of the spring 9 at the moment of water entry, so as to avoid the chickens hitting the water surface and causing broken wings and subcutaneous hematoma. After the chickens are stunned by electric shock, the lifting and locking mechanism 2 lifts the chickens in the electric shock pool 14 upward. When the spring 9 is compressed to a certain extent, the bottom surface of the fixing plate 10 will be compressed by the pressing ring 8 on the outside and the spring 7 at the bottom, which will provide greater buffering and avoid broken wings and subcutaneous hematoma. The connecting plate 6 is connected to the sliding frame 1 by the sliding groove 5 opened in the inner wall of the concave block 4 on the front and rear sides and slides left and right. Multiple universal wheels 15 are installed under the bottom plate 13 of the device for easy transportation.

[0035] The sliding frame 1 is connected to the lifting and locking mechanism 2 via the connecting rod 3. When the height needs to be adjusted, the spring 3 205 connected to the inner wall of the movable piece 203 is squeezed, and the movable piece 203 slides on the inner wall of the sliding frame 208, pulling the pin 204 out from the through hole 202 and pin hole 207 opened on the outer wall of the limiting block 201 and the support tube 206, thus releasing the locking of the limiting block 201 and the support tube 206. The limiting block 201 is connected to the connecting rod 3 for height adjustment. When the height is adjusted to a suitable position, the movable piece 203 is released, and the reset spring 3 205 locks the pin 204 into the through hole 202 and pin hole 207 to complete the height fixation. The rubber sleeve 209 is wrapped around the top of the support tube 206 to prevent the top of the support tube 206 from being bumped and damaged during the transfer process.
