Description

Technical Field

[0001] This utility model relates to the field of pig slaughtering technology, and in particular to a spraying device for pig slaughtering and processing. Background Technology

[0002] The primary purpose of spraying during pig slaughtering and processing is cleaning and hygiene assurance. High-pressure water jets effectively remove blood, feces, hair, and impurities from the pig's surface, reducing initial microbial contamination. Simultaneously, spraying lowers the pig's body temperature, inhibiting bacterial growth and creating clean conditions for subsequent quarantine and processing. This step is crucial for slaughter hygiene control, meeting food safety production standards, improving meat quality, reducing the risk of cross-contamination during processing, and ensuring the food safety and health of end consumers.

[0003] The spray system for pig slaughtering and processing pressurizes clean water or disinfectant via a water pump and delivers it through pipelines to the spray heads, creating a high-pressure water flow. As the pig carcass is conveyed by a conveyor, the spray heads rinse it from all directions, using the impact of the water flow to remove surface dirt and microorganisms. Its applications cover multiple stages of slaughtering and processing: rinsing away blood after bleeding, removing residual pig hair and skin after dehairing, cleaning the cavity after splitting, and secondary disinfection before cutting, ensuring hygiene standards are met at each stage. It is compatible with large-scale slaughtering lines, improving cleaning efficiency and meat safety.

[0004] In existing technologies, some spraying devices for pig slaughtering and processing generally use a water pump to deliver water to the nozzles to produce high-pressure water jets for spraying the pork. However, during spraying, the nozzles cannot spray the surface of the pork at the correct angle, creating blind spots and resulting in incomplete cleaning of the pork, leaving bloodstains and dirt residue, which affects subsequent processing. Therefore, a spraying device for pig slaughtering and processing is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a spraying device for pig slaughtering and processing, which aims to improve the existing technology. Some spraying devices for pig slaughtering and processing generally use a water pump to deliver water to the nozzle to produce a high-pressure water flow to spray the pork. However, during spraying, the nozzle cannot spray the surface of the pork at the correct angle, resulting in dead corners.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A spraying device for pig slaughtering and processing includes a cleaning tank. A servo motor is fixedly connected to the inner wall of the cleaning tank. A drive rod is fixedly connected to the drive end of the servo motor. A rotating rod is fixedly connected to the drive rod. A sliding ring is fixedly connected to the top of the rotating rod. A fixing rod is fixedly connected to the inner wall of the cleaning tank. A rotating column is rotatably connected to the inner wall of the fixing rod. A control rod is fixedly connected to the top of the rotating column. A mounting frame is fixedly connected to one end of the control rod. A disassembly assembly is installed on the inner wall of the mounting frame.

[0008] As a further description of the above technical solution:

[0009] The disassembly assembly includes a fixing rod, the outer wall of which is detachably connected to the inner wall of the mounting bracket, the inner wall of which is detachably connected to a housing, the inner wall of which is threaded with a threaded post, one end of which is fixedly connected to a conical block, and the outer wall of the fixing rod is fixedly connected to a nozzle plate.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the outer shell is fixedly connected to multiple fixing boxes. The inner wall of the fixing box is slidably connected to a limit post. The outer wall of the limit post is fixedly connected to a circular plate. One end of the limit post is fixedly connected to a wedge block.

[0012] As a further description of the above technical solution:

[0013] A return spring is fitted on the outer wall of the limiting post. The top end of the return spring is fixedly connected to the inner wall of the fixing box, and the bottom end of the return spring is fixedly connected to the top of the circular plate.

[0014] As a further description of the above technical solution:

[0015] The outer wall of the conical block contacts the outer wall of the wedge block, and the outer wall of the limiting post is detachably connected to the inner wall of the fixing rod.

[0016] As a further description of the above technical solution:

[0017] The outer wall of the control rod is slidably connected to the inner wall of the sliding ring, and the outer wall of the fixing rod is fixedly connected to the inner wall of the cleaning tank.

[0018] As a further description of the above technical solution:

[0019] A water pump is fixedly connected to the inner wall of the cleaning tank, and a water pipe is fixedly connected to the output end of the water pump. One end of the water pipe is fixedly connected to the inner wall of the nozzle plate.

[0020] As a further description of the above technical solution:

[0021] A fixing plate is fixedly connected to the top of the cleaning tank, an annular guide rail is fixedly connected to the outer wall of the fixing plate, a hook is slidably connected to the bottom of the annular guide rail, and a base plate is fixedly connected to the bottom of the cleaning tank.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the rotation of the rotating rod is driven by the start of the servo motor. At this time, the rotation of the rotating rod will drive the control rod to swing back and forth through the sliding ring. Since the control rod is rotatably connected to the top of the fixed rod through the rotating column, the swing of the tail of the control rod will drive the front end of the control rod to swing, thereby driving the mounting bracket to swing. This enables the spray nozzle plate to spray the surface of the pork evenly, making the spraying effect better and preventing bloodstains and dirt from remaining during spraying.

[0024] 2. In this utility model, rotating the threaded column causes the conical block to slide inside the outer shell. The sliding of the outer shell causes the conical block to no longer squeeze the wedge block. At this time, the return spring releases elastic potential energy, causing the wedge block to rebound towards the inner wall of the outer shell. At this time, the limiting column no longer jams the inner wall of the fixing rod, thereby realizing the disassembly of the nozzle plate, which is convenient for maintenance and replacement, and prevents the water outlet of the nozzle from becoming blocked after long-term use, thus reducing the spraying effect.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 2 to 4 This utility model provides an embodiment of a spraying device for pig slaughtering and processing, including a cleaning tank 1. The cleaning tank 1 provides installation and working space for the entire device. A servo motor 5 is fixedly connected to the inner wall of the cleaning tank 1. The servo motor 5 provides power output for the device. A drive rod 2 is fixedly connected to the drive end of the servo motor 5. The drive rod 2 transmits the power of the servo motor 5 to a rotating rod 3. The drive rod 2 is fixedly connected to the rotating rod 3. The rotating rod 3 drives the sliding ring 4 to move by rotating. The top of the rotating rod 3 is fixedly connected to the sliding ring 4. The sliding ring 4 causes the control rod 24 to slide inside it by rotating itself, thereby causing the control rod 24 to swing.

[0035] A fixed rod 8 is fixedly connected to the inner wall of the cleaning tank 1. The fixed rod 8 provides a rotation support point for the rotating column 6. The rotating column 6 is rotatably connected to the inner wall of the fixed rod 8. The rotating column 6 allows the control rod 24 to rotate around it. The top of the rotating column 6 is fixedly connected to the control rod 24. The control rod 24 swings to drive the mounting frame 7 and the nozzle plate 9 to swing so as to achieve uniform spraying. One end of the control rod 24 is fixedly connected to the mounting frame 7. The mounting frame 7 is used to install the nozzle plate 9 and the disassembly assembly. The disassembly assembly is installed on the inner wall of the mounting frame 7. The disassembly assembly facilitates the disassembly, maintenance or replacement of the nozzle plate 9. The outer wall of the control rod 24 is slidably connected to the inner wall of the sliding ring 4, so that when the rotating rod 3 rotates, the sliding ring 4 can drive the control rod 24 to swing.

[0036] The outer wall of the fixed rod 8 is fixedly connected to the inner wall of the cleaning box 1, so that the rotating column 6 can rotate on the inner wall of the fixed rod 8. The top of the cleaning box 1 is fixedly connected to the fixed plate 19, which provides installation support for the annular guide rail 18. The outer wall of the fixed plate 19 is fixedly connected to the annular guide rail 18, which provides a sliding path for the hook 22 to transport pork. The bottom of the annular guide rail 18 is slidably connected to the hook 22, which is used to suspend pork for transport and spraying. The bottom of the cleaning box 1 is fixedly connected to the bottom plate 23, which supports the entire cleaning box 1 and makes it stable.

[0037] Reference Figure 1 , Figure 5 and Figure 6 The disassembly assembly includes a fixing rod 8, which provides an installation position for the nozzle plate 9. The outer wall of the fixing rod 8 is detachably connected to the inner wall of the mounting frame 7, allowing the fixing rod 8 and the mounting frame 7 to be separated for easy disassembly. The inner wall of the mounting frame 7 is detachably connected to a housing 11, which provides installation space for components such as the conical block 12. The inner wall of the housing 11 is threadedly connected to a threaded post 10, which drives the conical block 12 to move by rotating. One end of the threaded post 10 is fixedly connected to the conical block 12, and the movement of the conical block 12 can squeeze or loosen the wedge block 16. The outer wall of the fixing rod 8 is fixedly connected to the nozzle plate 9, which is used to spray water to spray the pork.

[0038] Multiple fixing boxes 17 are fixedly connected to the outer wall of the outer casing 11. The fixing boxes 17 provide installation and sliding space for components such as the limiting post 13. The inner wall of the fixing box 17 is slidably connected to the limiting post 13. The limiting post 13 locks or releases the fixing rod 8 by sliding. The outer wall of the limiting post 13 is fixedly connected to a circular plate 15. The circular plate 15 is used to compress or cooperate with the movement of the return spring 14. One end of the limiting post 13 is fixedly connected to a wedge block 16. When the wedge block 16 is squeezed by the conical block 12, it drives the limiting post 13 to move. The outer wall of the limiting post 13 is fitted with a return spring 14. When the wedge block 16 is not squeezed, the return spring 14 pushes the circular plate 15 to reset the limiting post 13. The top end of the return spring 14 is fixedly connected to the inner wall of the fixing box 17, and the bottom end of the return spring 14 is fixedly connected to the top of the circular plate 15 so that the return spring 14 can stably exert its elastic effect.

[0039] The outer wall of the conical block 12 contacts the outer wall of the wedge block 16, ensuring that the conical block 12 can effectively squeeze the wedge block 16. The outer wall of the limiting post 13 is detachably connected to the inner wall of the fixing rod 8. The fixing rod 8 and the mounting bracket 7 are fixed by the limiting post 13 being inserted into the fixing rod 8. A water pump 20 is fixedly connected to the inner wall of the cleaning tank 1. The water pump 20 provides power for spraying to extract and transport water. A water pipe 21 is fixedly connected to the output end of the water pump 20. The water pipe 21 is used to transport the water extracted by the water pump 20 to the nozzle plate 9. One end of the water pipe 21 is fixedly connected to the inner wall of the nozzle plate 9, so that water can enter the nozzle plate 9 and spray out from it to achieve spraying.

[0040] Working principle: When it is necessary to spray the pork, the pork is suspended on the hook 22. The hook 22 then moves the pork to slide on the inner wall of the annular guide rail 18 to transport the pork. The water pump 20 draws water from the outside and transports it through the water pipe 21 to the inner wall of the nozzle plate 9, where it is sprayed out. At this time, the servo motor 5 starts, which drives the rotating rod 3 to rotate. Since the control rod 24 slides inside the sliding ring 4, the rotation of the rotating rod 3 will drive the control rod 24 to swing back and forth through the sliding ring 4. Since the control rod 24 is rotatably connected to the top of the fixed rod 8 through the rotating column 6, the swing of the tail of the control rod 24 will drive the front of the control rod 24 to swing, thereby driving the mounting frame 7 to swing. This allows the nozzle plate 9 to spray the surface of the pork evenly, resulting in a better spraying effect.

[0041] When the nozzle plate 9 needs to be disassembled, the threaded column 10 is rotated. The rotation of the threaded column 10 causes the conical block 12 to slide inside the housing 11. The sliding of the housing 11 causes the conical block 12 to no longer squeeze the wedge block 16. At this time, the return spring 14 releases its elastic potential energy, causing the wedge block 16 to rebound against the inner wall of the housing 11. At this time, the limiting column 13 no longer jams the inner wall of the fixing rod 8, thereby realizing the disassembly of the nozzle plate 9, which is convenient for maintenance and replacement, and prevents the water outlet from becoming blocked after long-term use, thus reducing the spraying effect.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
