Description

Technical Field

[0001] The present invention relates to the field of poultry slaughtering, and particularly to a fully automatic chicken slaughtering and defeathering device and method. Background Art

[0002] In the chicken slaughtering and processing industry, the defeathering process is crucial for the preparation of chicken products. Currently, most of the widely used fully automatic chicken slaughtering and defeathering devices in the market use the method of combining drum rotation and friction for defeathering; specifically, such devices usually include one or more drums with protrusions or special textures inside. When a chicken is sent into the drum, the drum rotates at a high speed driven by a motor, and the chicken body rubs against the inner wall of the drum and between the chicken bodies, and the chicken feathers are peeled off from the chicken by using the frictional force. With the advantages of relatively simple structure and high defeathering efficiency, this technical solution has been widely applied in the chicken slaughtering industry. However, the existing chicken slaughtering and defeathering devices based on the principle of drum rotation and friction have obvious technical defects. During the defeathering process, a large amount of the removed chicken feathers will remain inside the drum. Due to the lack of an effective chicken feather cleaning mechanism, as the defeathering work continues, the accumulated chicken feathers in the drum will become more and more; on the one hand, the accumulated chicken feathers will interfere with the effective friction between the subsequent chicken body and the drum, reducing the defeathering effect and efficiency; on the other hand, if the accumulated chicken feathers are not cleaned in time, it is easy to breed bacteria and produce odors, which not only affect the working environment but also may pose a threat to the health and safety of chicken products. In addition, manually cleaning the accumulated chicken feathers in the drum not only takes time and effort, increases the production cost, but also prolongs the downtime of the equipment, reducing the overall production efficiency.

[0003] In the prior art, a patent with the publication number of CN119014451A discloses a chicken slaughtering and defeathering device. Its basic principle is to support the whole device through a machine base, fix the defeathering drum on the machine base, coaxially arrange the defeathering disk inside the defeathering drum, drive the defeathering disk to rotate by a driving member, use the defeathering rods on the inner side of the defeathering drum and the upper side of the defeathering disk to defeather the chicken, and at the same time set an outer cylinder, a feeding component, a material distributing ring, a warm air component and a material suction component to achieve the timely treatment of chicken feathers, reduce waste and environmental pollution. However, although this technology has improved some of the original problems, there are still aspects that need to be further optimized to better meet the actual detection requirements.

[0004] 1. The diameter of the depilatory cylinder in the comparative document is fixed, and it cannot flexibly cope with chickens of different sizes. In actual production, the size of chickens varies greatly. If the chicken is smaller in size and is placed in a depilatory cylinder with a fixed diameter, the chicken will have a relatively large space to move around in the cylinder, which will not only prolong the depilation time. You must know that in large-scale assembly line production, the depilation time for chickens is strictly regulated, and the extension of time will inevitably affect the overall production progress. Moreover, the chicken is not limited in position during the depilation process, and it is easy for it to collide in the cylinder, causing damage to the chicken body and reducing product quality.

[0005] 2. The device only relies on the inner wall of the depilatory cylinder and the depilatory rod on the depilatory disc for depilation, and its contact area with the chicken is small. When dealing with larger chickens, the chicken is not easy to roll over during the depilation process, making it difficult for some feathers to fully contact the depilatory rod, resulting in poor depilation effect, and there may be more feathers left, which requires manual secondary processing, increasing labor costs and time costs.

[0006] Therefore, based on the above-stated viewpoints, there is still room for optimization in the existing technology for chicken depilation. Summary of the invention

Detailed implementation mode

[0040] The following is combined with Figures 1 to 13 To elaborate on the embodiments of the present invention in detail.

[0041] This application embodiment discloses a fully automatic chicken slaughtering and hair - removing device and method. This application is applied in the process of slaughtering and hair - removing chickens, which can efficiently and uniformly remove the hair of chickens of different sizes, loosen the chicken feathers sufficiently through hot water flushing to improve the hair - removing efficiency; and, this application can also effectively clean the remaining chicken feathers on the roller, hair - removal rod, inner wall of the main barrel and the sliding plate by means of water flow, wiping brush, etc. during and after the hair - removing process, and further improve the hair - removing effect through vibration assistance.

[0042] Embodiment 1: Refer to Figure 1 And Figure 2 As shown, it includes a bottom plate 1, support legs 10, a main barrel 11, a sliding shaft 12, a limiting cone 13, a roller 14, a hair - removal rod 15, a sliding plate 16 and a pipeline unit 2. A rotating shaft is rotatably installed on the support legs 10, and a main barrel 11 is arranged between the rotating shafts, that is, the rotating shaft can drive the main barrel 11 to rotate between the support legs 10 when driven by an external force.

[0043] A plurality of sliding shafts 12 distributed along its axis are slidably penetrated through both the upper and lower ends of the main barrel 11. A limiting cone 13 is rotatably provided at one end of the sliding shaft 12 located inside the main barrel 11. A roller 14 is rotatably arranged between the upper and lower corresponding limiting cones 13. A hair removal rod 15 is provided on the outer side of the roller 14. When the sliding shaft 12 is driven by an external force, the roller 14 can be driven by the limiting cone 13 to move in a direction towards or away from the axis of the main barrel 11. The roller 14 can drive the hair removal rod 15 on its outer side to rotate under the limitation of the upper and lower two limiting cones 13 to remove the chicken feathers, and the roller 14 can be driven by the sliding shaft 12 to move to adapt to chickens of different sizes.

[0044] A sliding plate 16 for supporting the chicken is slidably arranged inside the main barrel 11. When the chicken is being de-feathered, its bottom can be supported by the sliding plate 16 to prevent it from falling through the through-hole at the bottom of the main barrel 11.

[0045] A pipeline unit 2 for injecting water into the main barrel 11 is further provided on the roller 14.

[0046] In addition, the present invention also provides a fully automatic chicken slaughtering and de-feathering method, including the following steps: S1, De-feathering preparation: The sliding plate 16 rises to the top of the main barrel 11, and then the chicken to be de-feathered is placed on the sliding plate 16. The sliding plate 16 descends so that the chicken is located inside the main barrel 11.

[0047] S2, Initial washing: The pipeline unit 2 is started to discharge hot water into the main barrel 11. The hot water directly flushes the chicken feathers. At the same time, the main barrel 11 is driven by an external force to rotate, driving the chicken body to turn inside the main barrel 11 to achieve uniform flushing of the chicken body by the hot water and promote the chicken feathers to loosen fully; S3, Start de-feathering: The sliding shaft 12 drives the hair removal rod 15 on the outer side of the roller 14 to contact the chicken body, and an external force drives the roller 14 to rotate so that the hair removal rod 15 removes the chicken feathers, and the removed chicken feathers fall on the sliding plate 16.

[0048] S4, De-feathering completed: After the de-feathering operation is completed, the sliding plate 16 rises to take out the chicken; during the movement of the sliding plate 16, in cooperation with the pipeline unit 2 to inject water into the main barrel 11, the residual chicken feathers on the roller 14 and the hair removal rod 15 are washed off by the synergistic effect of the water flow and the sliding plate 16.

[0049] Subsequently, the rotating shaft drives the main barrel 11 to flip 180 degrees so that the chicken feathers attached to the sliding plate 16 fall off under the action of gravity.

[0050] Refer to Figure 3 and Figure 4As shown, it is the pipe unit 2 for injecting water into the main barrel 11. Specifically, the pipe unit 2 includes a bending groove 20, an external connecting pipe 21, a connecting pipe 22, a series pipe 23, and a bending pipe 24. The bending groove 20 is opened inside one side rotating shaft. One end of the bending groove 20 is rotatably inserted with the external connecting pipe 21. And the upper ends of any two drums 14 are jointly and rotatably connected through the connecting pipe 22. And a series pipe 23 is provided between the connecting pipes 22 to be connected through. And the other side port of the bending groove 20 is penetrated by the bending pipe 24. One end of the bending pipe 24 is connected to the connecting pipe 22 on one side. That is, the external water supply device can be connected to the external connecting pipe 21.

[0051] After that, the external water supply device can transmit water through the external connecting pipe 21 into the bending groove 20. Then the water in the bending groove 20 will enter the connecting pipe 22 on one side. Then the water in the connecting pipe 22 enters the through part. And the water in the connecting pipe 22 on one side will enter the connecting pipe 22 on the other side through the series pipe 23. At this time, all the drums 14 will be injected with water.

[0052] The middle part of the hair removal rod 15 is hollow, and the hair removal rod 15 is connected to the inside of the drum 14. And the water that enters the drum 14 will be discharged into the main barrel 11 through the hair removal rod 15. That is, the water will be directly sprayed onto the chicken. That is, at the initial stage, the hair removal rod 15 stirs the chicken to roll. Then the water will also enter the chicken feathers, further improving the loosening rate of the chicken feathers. After that, after the hair removal is completed, the rotating shaft drives the main barrel 11 to flip 180 degrees. At this time, the water sprayed from the hair removal rod 15 will wash away the chicken feathers attached to the sliding plate 16, the inner side wall of the main barrel 11, and other hair removal rods 15.

[0053] Both the connecting pipe 22 and the series pipe 23 are made of rubber telescopic material. That is, when the drum 14 moves, the connecting pipe 22 and the series pipe 23 will also expand and contract synchronously.

[0054] Refer to Figure 5 and Figure 6 As shown, that is, a driving unit 3 for driving the drum 14 to move is further provided outside the main barrel 11. Specifically, the driving unit 3 includes a double-thread 30, a driving groove 31, a ferrule 32, a gear disk 33, a driving shaft 34, and a driving gear 35. The double-thread 30 is opened outside several corresponding sliding shafts 12 at the upper end. And several driving grooves 31 distributed around its axis are opened outside the sliding shafts 12. That is, when the several sliding shafts 12 at the upper end are driven by an external force to rotate, they can reciprocate on the main barrel 11 through the double-thread 30.

[0055] On the outer side of the main barrel 11, two collars 32 corresponding to a number of upper and lower sliding shafts 12 are symmetrically sleeved. One side of the sliding shaft 12 slidably penetrates through the corresponding collar 32. A toothed disc 33 is rotatably arranged in the collar 32, and the toothed disc 33 meshes with the corresponding driving groove 31. When the toothed disc 33 is driven by an external force, it can rotate in the collar 32. When the toothed disc 33 rotates, it can drive the sliding shaft 12 to rotate through the driving groove 31. When the sliding shaft 12 rotates, it can reciprocate on the main barrel 11 through the double-thread 30, so as to indirectly drive the roller 14 to reciprocate, adapting to chickens of different sizes. The lower sliding shaft 12 can be driven by the corresponding toothed disc 33 to rotate, but since it is not provided with a double-thread 30, that is, it will not drive the main barrel 11 to move, but will move synchronously with the upper sliding shaft 12 and the main barrel 11, and indirectly limit and guide the main barrel 11.

[0056] A driving shaft 34 is also rotatably penetrated through the collar 32. A driving gear 35 meshing with the toothed disc 33 is sleeved on one side of the driving shaft 34 located inside the collar 32. That is, one end of the driving shaft 34 located outside the collar 32 is used to connect with an external driving motor. The main shaft of the external driving motor can drive the driving gear 35 to rotate through the driving shaft 34, and the driving gear 35 can drive the toothed disc 33 to rotate.

[0057] Refer to Figure 7 and Figure 8 As shown in

[0058] and

[0059] a driving assembly 4 for driving the roller 14 to rotate is arranged on the lower sliding shaft 12; specifically, the driving assembly 4 includes an annular groove 40, an external gear ring 41, a transmission shaft 42 and a transmission gear 43. The annular groove 40 is opened at the bottom of the roller 14. An external gear ring 41 is arranged on the inner top wall of the annular groove 40. One side of the lower sliding shaft 12 is provided with a transmission shaft 42 passing through the corresponding limiting cone 13 and located in the annular groove 40, and a transmission gear 43 meshing with the external gear ring 41 is sleeved on the outside of the transmission shaft 42.

[0060] When the lower sliding shaft 12 is driven by the toothed disc 33 to rotate, it can drive the transmission shaft 42 to rotate, and the transmission shaft 42 can drive the transmission gear 43 to rotate in the annular groove 40. At this time, the transmission gear 43 can drive the external gear ring 41 to rotate, and the external gear ring 41 can drive the roller 14 to rotate. Figure 9 、 Figure 10 and Figure 11As shown in the figure, a sliding assembly 5 is provided on the sliding plate 16. Specifically, the sliding assembly 5 includes a receiving groove 50, a wiping brush 51, a spiral groove 52, an arc-shaped plate 53, a circular cavity 54, a central shaft 55 and a cam 56. Several receiving grooves 50 are formed on the sliding plate 16 and correspond to several rollers 14 one by one. A wiping brush 51 is provided on the inner wall of the receiving groove 50. That is, after hair removal is completed, the up-and-down movement of the sliding plate 16 can wipe off the remaining chicken feathers on the hair removal rod 15 through the wiping brush 51. At the same time, the outer side of the sliding plate 16 can also scrape off the remaining chicken feathers on the inner wall of the main barrel 11.

[0061] A spiral groove 52 is formed on the outer side of the roller 14, and an arc-shaped plate 53 engaged with the spiral groove 52 is provided on the inner side wall of the wiping brush 51. That is, when the roller 14 rotates, the sliding plate 16 can be driven to move in the main barrel 11 through the arc-shaped plate 53. During the hair removal process, the rotation direction of the main barrel 11 rotates forward and backward, so that the sliding plate 16 can drive the chicken to move up and down in the main barrel 11.

[0062] To prevent the roller 14 from excessively clamping the chicken body and avoid the situation where the chicken body is stuck by the roller 14 when the sliding plate 16 descends, during this process, the sliding shaft 12 will drive the roller 14 to move reciprocally. At the same time, the sliding plate 16, as the supporting structure of the chicken body, will drive the chicken body to move up and down in the main barrel 11 under the cooperation of the spiral groove 52 and the arc-shaped plate 53, and the driving of the forward and backward rotation of the main barrel 11.

[0063] This moving method enables the chicken body to experience the repeated clamping of the roller 14 during the hair removal process. The reciprocating movement of the roller 14 and the up-and-down movement of the chicken body cooperate with each other, causing the contact angle between the chicken body and the hair removal rod 15 to continuously change. In the initial stage, hot water is sprayed onto the chicken body through the pipe unit 2 via the hair removal rod 15 to fully loosen the chicken feathers. During the hair removal process, the change in the hair removal angle of the chicken body enables the hair removal rod 15 to act on the chicken feathers more comprehensively and deeply. It can not only cover the chicken feathers on all parts of the chicken body, but also increase the friction force and contact area between the hair removal rod 15 and the chicken feathers, thereby further improving the hair removal efficiency of the chicken feathers.

[0064] In addition, under the action of the sliding assembly 5, the vibration force generated by the cam 56 is transmitted to the roller 14 and the chicken body, which can also assist the hair removal process, making the chicken feathers easier to fall off from the chicken body and further improving the efficiency and quality of the entire hair removal process.

[0065] A circular cavity 54 is provided inside the sliding plate 16, and a central shaft 55 rotates on the inner wall of the circular cavity 54. A cam 56 is sleeved on the outer side of the central shaft 55. That is, during the depilation process, the central shaft 55 is driven by an external force to drive the cam 56 to rotate in the circular cavity 54 to generate vibration, and the depilation efficiency is further improved by transmitting the vibration force to the roller 14. When the wiping brush 51 wipes off the chicken feathers attached to the depilation rod 15, the vibration force can also assist in detaching the chicken feathers from the depilation rod 15.

[0066] When the present invention is in operation, in order to prevent the chicken neck from being stuck between the receiving groove 50 and the drum 14, the following operation mode is adopted: First, the roller 14 is driven to move back and forth by the sliding shaft 12. This design has dual functions. On the one hand, it enables the device to adapt to chickens of different sizes; on the other hand, it effectively avoids the situation where the chicken's neck is stuck; when the roller 14 approaches the chicken body, its position will be continuously adjusted according to the size of the chicken body, and it will always maintain a suitable distance from the chicken body. At the same time, the receiving groove 50 on the sliding plate 16 and the roller 14 cooperate with each other tacitly. The wiping brush 51 on the inner wall of the receiving groove 50 and the spiral groove 52 on the outside of the roller 14 are meshed with each other through the arc plate 53. When the roller 14 rotates, it will drive the sliding plate 16 to move, and the chicken body will also move up and down in the main barrel 11. The position is continuously in a dynamic adjustment state, not fixed, which greatly reduces the possibility of the chicken's neck being stuck.

[0067] In addition, the moving distances of the rollers 14 are limited by the corresponding receiving grooves 50. Even if the rollers 14 move to the end of the receiving grooves 50, a certain gap will still remain between the rollers 14. This gap can effectively prevent the machine head from being clamped and stuck.

[0068] Secondly, during the depilation process, even if the chicken head is stuck in the receiving groove 50, there is a corresponding response mechanism; at this time, several rollers 14 will pre-clamp the chicken body first, and since the sliding plate 16 is reciprocating, the chicken head can be moved downward to allow the chicken head to escape from the corresponding receiving groove 50, and then the roller 14 stops clamping the chicken body, and the chicken body will fall onto the sliding plate 16. In normal use, after the roller 14 clamps the chicken body, a certain amount of redundant space will be reserved between the outer side of the roller 14 and the inner side wall of the receiving groove 50, so even if the chicken head falls into the receiving groove 50, it can still escape from the receiving groove 50 while the chicken body is being depilated by the roller 14.

[0069] Finally, in the initial washing stage, the pipeline unit 2 discharges hot water, and the main barrel 11 rotates to drive the chicken body to turn over, so that the chicken body is fully relaxed and the chicken feathers are loosened. Before entering the hair removal stage, the chicken body is already in a relatively stretched state, which reduces the probability of the chicken neck being stuck to a certain extent. Moreover, during hair removal, the vibration force generated by the cam 56 is transmitted to the drum 14 and the chicken body, which not only assists in the hair removal work, but also keeps the chicken body dynamic, avoiding long-term close contact between the local part of the chicken body and the drum 14, further preventing the chicken neck from being stuck between the receiving groove 50 and the drum 14, and effectively ensuring the efficient and stable operation of the device.

[0070] Embodiment 2: Refer to Figure 12 and Figure 13 As shown, on the basis of Embodiment 1, in order to drive the central shaft 55 to rotate, a power assembly 6 is arranged in the sliding plate 16; specifically, the power assembly 6 includes a strip-shaped groove 60, a vertical shaft 61, a vertical groove 62 and a rack 63. The strip-shaped groove 60 is opened inside the sliding plate 16. One end of the strip-shaped groove 60 communicates with the circular cavity 54, and the other side communicates to the outside of the sliding plate 16. A vertical shaft 61 is rotated in the strip-shaped groove 60. The vertical shaft 61 is connected to the central shaft 55 by a belt drive. That is, when the vertical shaft 61 is driven by an external force, it will drive the central shaft 55 to rotate through the transmission belt, so that the cam 56 rotates and generates a vibration force.

[0071] Moreover, a vertical groove 62 is opened on the inner wall of the main barrel 11, and a rack 63 is arranged on the inner wall of the vertical groove 62. The vertical shaft 61 is connected to the rack 63 by a gear drive. That is, when the sliding plate 16 is indirectly driven by the drum 14 to move in the up and down direction, the vertical shaft 61 can be driven to rotate itself by cooperating with the rack 63 in the vertical groove 62 through a gear drive.
