Description

Technical Field

[0001] This application belongs to the technical field of poultry processing equipment, and more specifically, relates to a scalding device for laying hens. Background Technology

[0002] Scalding tanks are essential equipment in the slaughtering process of laying hens. By immersing the hens in the scalding tank, subsequent defecation processing becomes much easier. With the development of the laying hen farming and slaughtering industries, higher demands are being placed on the performance and efficiency of scalding equipment.

[0003] Currently, various poultry scalding devices are available on the market. Some scalding devices use a simple scalding tank structure, requiring manual intermittent operation to complete the scalding process. This method is not only inefficient but also makes it difficult to ensure uniform scalding, resulting in poor scalding of some laying hens' feathers, affecting subsequent plucking processes. Furthermore, manual operation is labor-intensive and consumes significant labor costs. Other, more automated scalding devices, while achieving a certain degree of continuous scalding, have significant flaws in how the laying hens are secured. A common method is to use simple hooks to hold the hen's feet in place. To allow for quick retrieval, the hook's interface remains open, lacking a locking mechanism. However, in actual use, when laying hens are soaked in hot water, the current fixing method is often not secure enough due to buoyancy and water flow. The hens' feet can easily slip off, causing the hens to change their position or even fall off. On the one hand, this will cause uneven scalding of the laying hens, with some parts being over-scalded and others under-scalded, which will seriously affect product quality. On the other hand, the hens falling off may cause equipment failure or even require shutdown, which will greatly reduce production efficiency. Summary of the Invention

[0004] In view of this, the present application provides a scalding device for laying hens to solve the technical problem that the feet of laying hens are easy to slip off in the scalding equipment in the prior art.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] On the one hand, a scalding device for laying hens is provided, comprising:

[0007] Scalding tank;

[0008] A conveyor chain passes over the scalding tank;

[0009] The deflector bar is arranged parallel to the portion of the conveyor chain located above the scalding tank;

[0010] The chicken rack moves along the conveyor chain;

[0011] The chicken hanging rack includes:

[0012] The rotating structure has a reset mechanism.

[0013] The hook portion has a hook notch; the hook portion is connected to the conveyor chain via the rotating structure.

[0014] The control unit is connected to the hook unit;

[0015] When the rotating structure is in the reset state, the opening of the hook notch faces the side of the conveying direction; when the hook part moves with the conveyor chain to immerse the laying hen in the scalding tank, the steering baffle pushes the control unit to turn the hook part so that the opening of the hook notch faces the conveying direction.

[0016] In some embodiments, the rotating structure includes:

[0017] A connecting sleeve, one end of which is closed and hinged to the conveyor chain, and the other end hanging downwards;

[0018] The connecting rotating core has one end inserted into the drooping end of the connecting sleeve and can rotate relative to the connecting sleeve; the other end of the connecting rotating core is connected to the hook part.

[0019] A limiting post is coaxially disposed inside the connecting sleeve, with its free end expanding to form a limiting clamp head;

[0020] The limiting plate has a through hole in the center; the limiting plate is connected to the insertion end of the connecting rotating core, and the limiting post passes through the through hole and is limited by the limiting plate to the limiting head.

[0021] In some embodiments, the limiting disc is fitted to the end face of the insertion end of the connecting rotating core, and the outer end of the connecting rotating core is provided with a connecting bolt that connects to the limiting disc;

[0022] The end face of the connecting core insertion end is provided with a receiving groove, and the limiting card head is accommodated in the receiving groove.

[0023] In some embodiments, the reset mechanism includes a torsion spring adapted to push the connecting sleeve and the limiting disc to rotate relative to each other, thereby resetting the rotating structure.

[0024] In some embodiments, the inner bottom of the closed end of the connecting sleeve is provided with a mounting groove, one end of the limiting post is connected to the bottom of the mounting groove, the torsion spring is disposed in the mounting groove and surrounds the limiting post, one end of the torsion spring is connected to the connecting sleeve, and the other end is connected to the limiting plate.

[0025] In some embodiments, the reset mechanism further includes a limiting notch disposed circumferentially along the lower end of the connecting sleeve; the control unit is connected to the outer periphery of the connecting core and is located within the limiting notch;

[0026] When the rotating structure is in the reset state, the control unit abuts against one end of the limiting notch; when the hook part is pushed to the limit position by the steering bar, the control unit abuts against the other end of the limiting notch.

[0027] In some embodiments, when the rotating structure is in the reset state, the control unit protrudes from the radial side of the connecting rotating core and the protrusion direction is perpendicular to the conveying direction, and the steering stop is located on the radial side of the connecting rotating core and is opposite to the control unit.

[0028] The beneficial effects of the scalding device for laying hens provided in this application embodiment are as follows: Compared with the prior art, in the scalding device for laying hens in this application embodiment, when the hook part moves with the conveyor chain, the rotating structure is reset under the action of the reset mechanism, so that the hook part rotates to the side where the opening of the hook notch faces the conveying direction, making it convenient for the operator to stand on the side to hang the chicken feet on the hook part, or to remove the chicken feet from the hook part.

[0029] When the hook part moves with the conveyor chain to immerse the laying hen in the scalding tank, the steering baffle pushes the control unit to turn the hook part so that the opening of the hook notch faces the conveying direction. This ensures that the hen's feet are firmly stuck in the hook notch due to the resistance of the water in the scalding tank, thus greatly reducing the possibility of the hen's feet slipping off and ensuring the scalding effect.

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" or "several" means two or more, unless otherwise explicitly specified.

[0041] Please refer to the following: Figures 1 to 4 The scalding apparatus for laying hens provided in the embodiments of this application will now be described. A scalding apparatus for laying hens includes:

[0042] Scalding tank;

[0043] The conveyor chain passes over the scalding tank;

[0044] The deflector bar is set parallel to the portion of the conveyor chain located above the scalding tank;

[0045] The chickens are hung on racks and move along the conveyor chain.

[0046] The chicken racks include:

[0047] The rotating structure has a reset mechanism.

[0048] The hook section has a hook notch; the hook section is connected to the conveyor chain via a rotating structure.

[0049] The control unit is connected to the hook unit;

[0050] When the rotating structure is in the reset state, the opening of the hook notch faces the side of the conveying direction; when the hook part moves with the conveyor chain to immerse the laying hen in the scalding tank, the steering baffle pushes the control unit to turn the hook part so that the opening of the hook notch faces the conveying direction.

[0051] Compared with the prior art, in the scalding device for laying hens in this application embodiment, when the hook part moves with the conveyor chain, the rotating structure is reset by the reset mechanism, so that the hook part rotates to the side where the opening of the hook notch faces the conveying direction, making it convenient for the operator to stand on the side to hang the chicken feet on the hook part, or to remove the chicken feet from the hook part.

[0052] When the hook part moves with the conveyor chain to immerse the laying hen in the scalding tank, the steering baffle pushes the control unit to turn the hook part so that the opening of the hook notch faces the conveying direction. This ensures that the hen's feet are firmly stuck in the hook notch due to the resistance of the water in the scalding tank, thus greatly reducing the possibility of the hen's feet slipping off and ensuring the scalding effect.

[0053] In this embodiment, the structure of the scalding tank and the conveyor chain can refer to the structure of conventional scalding equipment. For example, the scalding tank can be a rectangular tank made of stainless steel, and a defecation mechanism can be set at the rear of the scalding tank, or the defecation can be performed in the subsequent process; the conveyor chain passes over the scalding tank and extends to the preceding and following processes at both ends, so that the conveyor chain sends the laying hens from the preceding process into the scalding tank for scalding, and then transports them to the subsequent process.

[0054] The hook section of the chicken hanging rack can be based on the hook structure of conventional scalding equipment. Its hook notch is always open, without a locking mechanism, allowing operators to easily hang chicken feet on the hook notch. The hook section is connected to the conveyor chain via a rotating structure, allowing it to rotate and change the orientation of the hook notch. The rotating structure has a reset mechanism; under the action of this mechanism, the hook section can reset to the side with the hook notch opening facing the conveyor direction when no external force is applied, facilitating hooking or removing the laying hens by operators on the side.

[0055] The section of the conveyor chain above the scalding tank is equipped with a deflector bar parallel to its length. A control unit is connected to the hook section. When the chicken hanger passes over the scalding tank with the conveyor chain, the control unit is pushed by the deflector bar, causing the hook section to rotate so that the opening of the hook notch faces the conveying direction. At this time, because the resistance of the pool water to the laying hens is opposite to the conveying direction, while the opening of the hook notch faces the same direction, the chicken's feet are firmly secured within the hook notch. After the chicken hanger leaves the scalding tank with the conveyor chain, a reset mechanism returns the hook section to the side where the opening of the hook notch faces the conveying direction.

[0056] Please see Figure 2 As a specific embodiment of the scalding device for laying hens provided in this application, the rotating structure includes:

[0057] The connecting sleeve is closed at one end and hinged to the conveyor chain, while the other end hangs downwards.

[0058] The connecting rotating core has one end inserted into the drooping end of the connecting sleeve and can rotate relative to the connecting sleeve; the other end of the connecting rotating core is connected to the hook part.

[0059] A limiting post is coaxially located inside the connecting sleeve, with its free end expanding to form a limiting clamp.

[0060] The limiting plate has a through hole in the center; the limiting plate is connected to the insertion end of the connecting rotating core, and the limiting post passes through the through hole and is limited by the limiting plate and the limiting clamp head.

[0061] In this embodiment, a connecting core is inserted into the drooping end of the connecting sleeve, thereby protecting the internal structure and preventing the entry of water, feathers, or other debris. The limiting disc and the limiting post's limiting clamps keep the connecting sleeve and the connecting core in an inserted state.

[0062] In practical implementation, the connecting sleeve is a circular sleeve with its upper end closed and fixed with an ear plate. The ear plate is hinged to the conveyor chain, allowing the connecting sleeve to hang freely, forming a drooping end at its lower end. The connecting rotating core is a short cylinder, its upper end inserted into the lower end of the connecting sleeve, allowing it to rotate freely. A fixed hook is welded to the lower end of the connecting rotating core.

[0063] Please see Figure 2 As a specific embodiment of the scalding device for laying hens provided in this application, the limiting plate is attached to the end face of the insertion end of the connecting core, and the outer end of the connecting core is provided with a connecting bolt connected to the limiting plate.

[0064] The end face of the connecting core insertion end is provided with a receiving groove, and the limiting card head is accommodated in the receiving groove.

[0065] In this embodiment, the limiting plate and the limiting post can be matched first, and then the connecting rotating core can be inserted into the lower end of the connecting sleeve. The limiting plate and the connecting rotating core can be fixed from the outer end of the connecting rotating core using connecting bolts, thereby completing the installation. The assembly process is more convenient and reduces the production difficulty.

[0066] In practice, the free end of the limiting post can be threaded, and a nut is then installed on the free end of the limiting post to form a limiting clamp. To prevent the nut from falling off after long-term rotation, the threads on the limiting post can be broken after the nut is installed. The limiting disc is a circular disc with a through hole in the center. The end face of the limiting disc coincides with the end face of the connecting rotating core insertion end and is fixed by connecting bolts.

[0067] Please see Figure 2 As a specific embodiment of the scalding device for laying hens provided in this application, the reset mechanism includes a torsion spring; the torsion spring is adapted to push the connecting sleeve and the limiting plate to rotate relative to each other so that the rotating structure is reset.

[0068] In this embodiment, when the hook part rotates through the rotating structure, the torsion spring is compressed or stretched. When the hook part is no longer subject to external force, the elastic force of the torsion spring causes the rotating structure to reset.

[0069] Please see Figure 2 As a specific embodiment of the scalding device for laying hens provided in this application, the inner bottom of the closed end of the connecting sleeve is provided with an installation groove, one end of the limiting post is connected to the bottom of the installation groove, a torsion spring is provided in the installation groove and surrounds the limiting post, one end of the torsion spring is connected to the connecting sleeve, and the other end is connected to the limiting plate.

[0070] This embodiment has a more reasonable structure and is easier to install. In practice, the torsion spring can be installed into the mounting slot first, with one end connected to the connecting sleeve and the other end connected to the limiting plate. Then, the limiting plate can be installed in place, and finally, the other parts can be installed.

[0071] Please see Figure 3 and Figure 4 As a specific embodiment of the scalding device for laying hens provided in this application, the reset mechanism further includes a limiting notch provided circumferentially along the lower end of the connecting sleeve; the control unit is connected to the outer periphery of the connecting core and is located within the limiting notch;

[0072] When the rotating structure is in the reset state, the control unit abuts against one end of the limit notch; when the hook part is pushed to the limit position by the steering stop bar, the control unit abuts against the other end of the limit notch.

[0073] In this embodiment, the position of the control part is limited by the limiting notch, thereby limiting the reset angle and maximum rotation angle of the hook part.

[0074] In practice, the limiting notch is at approximately 90° circumferentially at the lower end of the connecting sleeve. When the hook is not subjected to external force, the control unit abuts against one end of the limiting notch under the action of the reset mechanism of the rotating structure, accurately positioning the hook in the position where the opening of the hook notch faces the conveying direction. After the chicken rack moves above the scalding tank with the conveyor chain, the control unit is pushed by the deflector bar to abut against the other end of the limiting notch, thus ensuring that the hook is accurately positioned where the opening of the hook notch faces the conveying direction.

[0075] Please see Figure 3 and Figure 4 As a specific embodiment of the scalding device for laying hens provided in this application, when the rotating structure is in the reset state, the control part protrudes from the radial side of the connecting rotating core and the protrusion direction is perpendicular to the conveying direction. The steering baffle is located on the radial side of the connecting rotating core and is opposite to the control part.

[0076] In practice, the deflector bar is located below the conveyor chain and at the same height as the connecting rotor. The deflector bar is located on the side of the connecting rotor where the control unit is located, so that when the connecting rotor passes the deflector bar, the deflector bar pushes the control unit, causing the connecting rotor to rotate.

[0077] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
