Description

Technical Field

[0001] This invention relates to the field of special equipment for agricultural and sideline food processing, specifically a poultry defecation device for slaughtering. Background Technology

[0002] Defeathering during poultry slaughter is an essential and crucial step in meat processing. After defecation, the carcass surface is easier to thoroughly clean, cool, and remove internal organs, preventing feathers from contaminating muscle tissue and conforming to cooking and eating habits, resulting in clean, safe, edible poultry products that meet market standards.

[0003] When processing fattened ducks on an automated production line, the ducks are first sent to a scalding tank to soften their feathers, and then sent to a feather removal device where the friction between the rubber rods and the duck's body removes the feathers. However, due to the special growth environment and feeding methods of the fattened ducks, after they are hung up and bled, some of their feathers are not completely soaked when they enter the scalding tank on the production line. After entering the automatic feather removal equipment, it is very difficult to remove some of the feathers from the fattened ducks, especially the tail feathers, which are almost entirely done manually, affecting the feather removal efficiency.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1-8 The diagram shows a poultry slaughtering and defecation device, including a device base 1 and a housing 2 fixedly installed on the top of the device base 1. Four mounting rings 3 are rotatably installed on the inner side of the housing 2, and multiple mounting seats 4 are centrally symmetrically distributed on the inner ring of the mounting rings 3. Multiple defecation rods 5 are centrally symmetrically distributed on the outer side of the mounting seats 4. The defecation rods 5 are made of rubber, so that when the defecation rods 5 come into contact with the fat duck, the flexibility of the defecation rods 5 allows them to adhere to the outer side of the fat duck, improving defecation efficiency and facilitating the removal of tail feathers from the fat duck. A feeding bracket 6 is provided on the inner side of the housing 2, which feeds the scalded fat duck into the housing 2.

[0022] The hair removal mechanism includes multiple positioning cylinders 7 centrally symmetrically fixedly mounted on the outer ring of the mounting ring 3. The positioning cylinders 7 enable the hair removal rod 5 to reciprocate and rotate. The hair removal mechanism also includes an annular bracket 10 fixedly mounted on the outer ring of the mounting ring 3. A first toothed ring 11 is fixedly mounted on the outer side of the annular bracket 10. Two symmetrically distributed support plates 12 are fixedly mounted on the top of the housing 2. A rotating rod 13 is rotatably mounted between the two support plates 12. Two first gears 14 are fixedly mounted on the outer side of the rotating rod 13, and the first gears 14 on the two rotating rods 13 are staggered. The four first gears 14 mesh with the four first toothed rings 11 respectively. Two drive motors 15 are fixedly mounted on the outer side of the support plate 12 located at the left end of the housing 2. The output ends of the two drive motors 15 are respectively connected to the two rotating rods. One end of 13 is fixedly connected, and the outputs of the two drive motors 15 rotate in opposite directions, causing the two drive motors 15 to drive the two rotating rods 13 to rotate in opposite directions. The rotating rods 13 drive the first gear ring 11 to rotate through the first gear 14, and the first gear ring 11 drives the mounting ring 3 to rotate, causing the mounting ring 3 to drive the defecation rod 5 to make a circular motion through the mounting base 4. The four mounting rings 3 rotate in staggered and opposite directions to achieve rapid defecation of the fat duck. Five positioning rings 16 are fixedly installed on the inner side of the shell 2. The outer side of the mounting ring 3 contacts the outer side of the two adjacent positioning rings 16, so that the positioning rings 16 provide sealing support for the mounting ring 3. An insert 17 is fixedly installed on the side of the mounting base 4 away from the defecation rod 5. The insert 17 penetrates the positioning cylinder. 7. The mounting base 4 is rotatably mounted inside the positioning cylinder 7. A conical wheel 18 is fixedly mounted on the end of the insertion cylinder 17 away from the mounting base 4. An installation cylinder 19 is provided inside the annular bracket 10. One end of the installation cylinder 19 is fixedly mounted on the outside of the adjacent positioning ring 16. Multiple centrally symmetrically distributed first racks 20 are fixedly mounted on the end of the installation cylinder 19 away from the positioning ring 16. When the mounting base 4 makes a circular motion, it can drive the conical wheel 18 on the insertion cylinder 17 to contact the first racks 20 on the installation cylinder 19, so that the first racks 20 drive the insertion cylinder 17 to rotate through the conical wheel 18, so that the insertion cylinder 17 drives the mounting base 4 to rotate, thereby realizing the rotation of multiple hair removal rods 5. The inner side of the positioning cylinder 7 is also provided with a rotating assembly for rotating the hair removal rods 5. The outer side of the annular bracket 10 Each side of the ring bracket 10 is fixedly mounted with a convex ring 36, and the outer side of the positioning ring 16 is provided with an annular groove for mounting the convex ring 36. This allows the ring bracket 10 to rotate along the inner side of the annular groove along the convex ring 36 when rotating, improving the stability of the rotation of the ring bracket 10. A rubber ring 37 is fixedly mounted on the end of the positioning cylinder 7 away from the conical wheel 18, and the outer side of the rubber ring 37 contacts the outer side of the mounting base 4. This rubber ring 37 improves the sealing between the mounting base 4 and the positioning cylinder 7, preventing water accumulation inside the positioning cylinder 7. A fixing ring 38 is fixedly mounted on the outer side of the insertion cylinder 17, and the outer side of the fixing ring 38 contacts the side of the positioning cylinder 7 away from the mounting base 4. The fixing ring 38 provides a limit for the insertion cylinder 17, preventing the insertion cylinder 17 from detaching from the positioning cylinder 7, and improving the stability of the rotation of the insertion cylinder 17.The rotary assembly includes two symmetrically fixed positioning blocks 39 mounted inside the positioning cylinder 7. Two slip rings 40 are fixedly mounted between the two positioning blocks 39. Two sliders 41 are slidably mounted on the outer side of the slip rings 40. The sliders 41 are fixedly mounted on the side of the mounting base 4 near the insertion cylinder 17. An arc-shaped spring 42 is sleeved on the outer side of the slip rings 40 and fixedly mounted between the sliders 41 and adjacent positioning blocks 39. When the mounting base 4 rotates, it can drive the sliders 41 to move along the outer side of the slip rings 40, compressing the arc-shaped spring 42. When the conical wheel 18 moves away from the first rack 20, the rebound force of the arc-shaped spring 42 resets the sliders 41. Thus, when the conical wheel 18 contacts and moves away from the next first rack 20, the mounting base 4 can repeatedly rotate and swivel. The mounting base 4 drives the defecation rod 5 to move synchronously, improving the defecation efficiency of the fat duck.

[0023] Example 2: Please refer to Figures 4-6 This embodiment further illustrates Example 1. The adjusting mechanism shown in the figure includes a pusher 8 slidably mounted inside the mounting base 4. The pusher 8 can push the hair removal rod 5 to move. The adjusting mechanism also includes a push rod 21 fixedly mounted on the side of the pusher 8 away from the hair removal rod 5. The push rod 21 slidably extends to the outside of the insert 17. A slide rod 22 is fixedly mounted on the end of the push rod 21 away from the pusher 8. A pulley 23 is rotatably mounted on the end of the slide rod 22 away from the push rod 21. A rotating ring 24 is rotatably mounted on the inner side of the annular bracket 10. An arc-shaped groove is provided on the outer side of the rotating ring 24 for the pulley 23 to slide in a limited manner. A slide frame 25 is provided on the outer side of the push rod 21. The slide frame 25 is fixedly mounted on the inner side of the annular bracket 10, and the slide rod 22 is slidably mounted on the outer side of the slide frame 25. When the rotating ring 24 rotates, it can drive the pulley 23 to move through the arc-shaped groove. The pulley 23 drives the slide rod 22 along the outer side of the slide frame 25, and the slide rod 22 can... Push rod 21 moves along the inner side of insert 17, causing push rod 21 to push push frame 8 along the inner side of mounting base 4, realizing the movement of multiple feather removal rods 5, making it easier for feather removal rods 5 to adhere to the feathers of fat duck. A second rack 26 is fixedly installed on the outer side of rotating ring 24, and a gear motor 27 that cooperates with the second rack 26 is fixedly installed on the inner side of ring bracket 10, so that when the gear motor 27 runs, it can drive rotating ring 24 to rotate through the second rack 26. Two limiting rings 43 are fixedly installed on the inner side of ring bracket 10, and rotating ring 24 is rotatably installed between the two limiting rings 43, so that rotating ring 24 can rotate between the two limiting rings 43, improving the stability of rotating ring 24. Multiple centrally symmetrically distributed limiting rods 44 are fixedly installed on the inner side of mounting base 4, and the limiting rods 44 slide through push frame 8, so that the limiting rods 44 provide support for push frame 8, so that push frame 8 increases the support force on feather removal rods 5.

[0024] Example 3: Please refer to Figures 2-8This embodiment further illustrates other embodiments. The cleaning mechanism shown in the figure includes two symmetrically fixed retaining rings 9 installed inside the housing 2. The retaining rings 9 can collect duck feathers. The cleaning mechanism also includes two symmetrically fixed retaining rings 28 installed inside the housing 2. The two retaining rings 28 are respectively located outside the two retaining rings 9. A second toothed ring 29 is rotatably installed at both ends of the retaining ring 28. A matching second gear 30 is provided on the outer side of the second toothed ring 29, and the second gear 30 is fixedly installed on the outer side of the adjacent rotating rod 13, so that when the rotating rod 13 rotates, it can drive the second toothed ring 29 to rotate through the second gear 30. A U-shaped scraper 31 is fixedly installed between the two adjacent second toothed rings 29. The U-shaped scraper 31 is slidably installed between the housing 2 and the retaining rings 9, and the outer side of the U-shaped scraper 31 is in contact with the inner ring of the retaining ring 28, so that when the second toothed ring 29 rotates... Multiple U-shaped scrapers 31 can be driven to move in a circular motion along the inner side of the housing 2, the inner side of the retaining ring 9, and the inner ring of the retaining ring 28, which facilitates the scraping of feathers adhering to the inner side of the housing 2, the inner side of the retaining ring 9, and the inner ring of the retaining ring 28. Four nozzles 32 are installed on the inner side of the positioning ring 16 in a centrally symmetrical distribution. A drain rack 33 is fixedly installed on the outer side of the housing 2. The nozzles 32 are connected to the drain rack 33 through water pipes, so that the drain rack 33 can input water into the nozzles 32 through water pipes. The nozzles 32 can wash the feathers on the mounting ring 3, the mounting base 4, and the feather removal rod 5, so as to flush the feathers into the space between the retaining ring 9 and the housing 2. A collection box 34 is fixedly installed between the housing 2 and the device base 1, and the collection box 34 is connected to the two retaining rings 28 through two discharge pipes 35 respectively. The U-shaped scrapers 31, together with the nozzles 32, send the feathers and water into the collection box 34 through the discharge pipes 35 to achieve the cleaning of the feathers.

[0025] Working principle: First, the feeding bracket 6 feeds the scalded duck into the housing 2. The gear motor 27 drives the rotating ring 24 to rotate along the inner side of the annular bracket 10 via the second rack 26. The rotating ring 24 drives the pulley 23 to move through the arc groove. The pulley 23 drives the sliding rod 22 to move along the outer side of the slide frame 25. The sliding rod 22 drives the push rod 21 to move along the inner side of the insert 17. The push rod 21 pushes the push frame 8 to move along the inner side of the mounting base 4. The push frame 8 can drive multiple plucking rods 5 to move synchronously. Utilizing the flexibility of the plucking rods 5, the plucking rods 5 adhere to the feathers of the duck, making it easy for the plucking rods 5 to bend and press against the tail feathers of the duck. Subsequently, the two drive motors 15 drive the corresponding two rotating rods 13 to rotate in opposite directions. The rotating rod 13 drives the two first gears 14 on its outer side to rotate, and the first gears 14 drive the corresponding first gear rings 11 to rotate. Since the first gears 14 on the two rotating rods 13 are staggered, the four first gear rings 11 can rotate in staggered and opposite directions. The first gear rings 11 drive the ring bracket 10 to rotate along the inner side of the housing 2, so that the ring bracket 10 drives multiple positioning cylinders 7 to perform circumferential motion through the mounting ring 3. The positioning cylinders 7 can drive the hair removal rods 5 on the mounting base 4 to perform synchronous circumferential motion. At the same time, the mounting base 4 drives the conical wheel 18 on the insertion cylinder 17 to contact a first rack 20 on the mounting cylinder 19, so that the first rack 20 drives the conical wheel 18 to rotate, and the conical wheel 18 drives the mounting base 19 to rotate. 4. Rotating along the inner side of the positioning cylinder 7, the mounting base 4 drives the hair removal rod 5 to perform a circular motion around the positioning cylinder 7. Simultaneously, the mounting base 4 drives the slider 41 to move along the outer side of the slip ring 40. The slider 41 compresses the arc spring 42. As the mounting ring 3 rotates, when the conical wheel 18 moves away from the first rack 20, the rebound force of the arc spring 42 resets the slider 41. Thus, as the conical wheel 18 contacts and moves away from the next first rack 20, the mounting base 4 can repeatedly rotate and return. The mounting base 4 drives the hair removal rod 5 to move synchronously. The hair removal rod 5 can perform a circular motion around the mounting ring 3 and a reciprocating circular motion around the positioning cylinder 7 simultaneously, allowing the hair removal rod 5 to quickly... The process involves removing feathers from the fat duck, particularly the tail feathers which are more difficult to remove. Water is then pumped through a drain pipe from the drain rack 33 into the spray nozzle 32, which washes the feathers on the mounting ring 3, mounting base 4, and feather removal rod 5, flushing them between the retaining ring 9 and the housing 2. Simultaneously, a rotating rod 13 equipped with a second gear 30 drives a second gear ring 29 to rotate, causing the second gear ring 29 to rotate a U-shaped scraper 31 in a circular motion. This sends the feathers from the housing 2, retaining ring 9, and retaining ring 28 through the discharge pipe 35 into the collection box 34, cleaning the feathers. Finally, the feeding bracket 6 delivers the feathered fat duck, achieving a rapid feather removal process suitable for automated production line processing.
