Description

Technical Field

[0001] This invention relates to the field of pork processing technology, specifically to a meat unloading device and method for pork processing. Background Technology

[0002] Pork refers to the meat of domestic pigs, animals of the Suidae family. As one of the most important animal-based foods on the table, pork is characterized by its relatively soft fibers, less connective tissue, and high intramuscular fat content in its muscle tissue. It is easy to raise and has the characteristics of fine bones, few tendons, and a lot of meat, making it the most commonly consumed type of meat in daily life.

[0003] Currently, in the pork processing process, the whole pig is usually hung upside down for dehairing, processing, cleaning, and disinfection. Then, it is cut in half using a cutting device and unloaded from the hook, completing a complete processing procedure. Currently, the unloading process is generally done manually. However, because half a pig is quite heavy, the workload is large, and the risk of hand injury is inevitable from unloading meat on the hook for a long time. Summary of the Invention

[0004] The purpose of this invention is to provide a meat unloading device and method for pork processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a meat unloading device for pork processing, comprising a conveyor and a conveyor frame, wherein a circulating conveying trough is provided on one side of the bottom of the conveyor, and a conveying block is slidably connected to the inner groove of the circulating conveying trough via a transmission chain; a conveyor belt is provided on one side of the top of the conveyor frame, and anti-fall plates are welded to both sides of the top of the conveyor frame; a main rod is welded to one end of the bottom of the conveying block, and hook rods are rotatably connected to the outer arcs on opposite sides of the main rod; a baffle is welded to the bottom of the conveyor at a position parallel to the hook rods; a rotating groove is provided in the inner groove of the main rod relative to the hook rods; a rotating block is welded to one end of the hook rod relative to the rotating groove, and the rotating block engages with and is rotatably connected to the rotating groove; and a side roller belt is provided on the inner wall of the anti-fall plate via a rotating roller.

[0006] In a further embodiment, a rotating rod is welded to the end of the rotating block away from the hook rod, the rotating rod is rotatably connected to the inner wall of the rotating groove, and a spring-loaded spring is sleeved on the outer side of the rotating rod.

[0007] In a further embodiment, the rotating groove has an annular groove extending through the inner wall of the main rod, and a semi-arc plate is welded to the outer arc of the rotating block near the annular groove. The semi-arc plate engages with and is rotatably connected to the annular groove, and a stop block is welded to the top of the inner groove of the annular groove.

[0008] In a further embodiment, an arc-shaped groove is formed on the inner wall of the annular groove away from the semi-arc plate, and an arc-shaped rod is welded to the inner wall of the arc-shaped groove. A sliding block is sleeved and slidably connected to the outer side of the arc-shaped rod.

[0009] In a further embodiment, the sliding block engages with and is slidably connected to the arcuate groove, and an arcuate spring is welded between the side of the sliding block away from the semi-arc plate and the inner wall of the arcuate groove.

[0010] In a further embodiment, the conveyor frame is welded to the two side walls near the anti-fall plate, and a groove is provided on the top side of the side plate. A sliding rod is welded to the inner wall of the groove, and a slider is slidably connected through the sliding rod. The slider engages with and is slidably connected to the groove.

[0011] In a further embodiment, a buffer rod is rotatably connected between the slider and the anti-fall plate on opposite sides, and a buffer spring is welded between the side of the slider away from the conveyor frame and the inner wall of the chute.

[0012] In a further embodiment, an installation block is inserted and plugged into one end of the conveyor frame, and a cleaning pad is adhered to one side of the installation block. The cleaning pad is in contact with the conveyor belt for scraping.

[0013] In a further embodiment, a connecting rod is welded to one side of the mounting block relative to the conveyor frame, and a slot is provided on the outer wall of the conveyor frame relative to the connecting rod, and the connecting rod engages with the slot.

[0014] Preferably, the unloading method based on the above-mentioned unloading device for pork processing includes the following steps:

[0015] A1. During use, the pork is processed by scraping, washing, disinfecting and cutting at the front end, so that the whole pig is divided into two. At this time, the pork is hung upside down by a hook rod, and then the chain in the circulating conveyor trough is driven by a motor to rotate in a circular manner. After that, the chain drives the conveyor block to move forward in the circulating conveyor trough.

[0016] A2. The main rod and hook rod transport pork forward. When the hook rod reaches the position of the baffle, the baffle blocks the hook rod and makes it rotate to a parallel direction.

[0017] A3. After the hook rod moves out of the baffle position, the weight of the pork causes the hook rod to continue to rotate downwards. At this time, the tip of the hook rod is facing down, and the pork will naturally slide down onto the conveyor belt of the lower conveyor frame and be conveyed forward.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] This invention utilizes a rotating, spring-loaded hook rod structure. When pork needs to be unloaded after processing, a limiting structure prevents the hook rod from rotating. The weight of the pork then causes the hook rod to flip, allowing the pork to automatically slide down for unloading. This eliminates the need for manual operation, improving processing efficiency, reducing manual labor, and minimizing the risk of hand injuries. Furthermore, a conveyor structure below the unloading point, with a protective buffer structure, facilitates the transport and loading of the unloaded pork for further processing. The protective buffer structure also ensures more stable unloading and transport of the pork. Attached Figure Description

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below. 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.

[0028] Example 1

[0029] Please see Figure 1-2 This embodiment provides a pork unloading device, including a conveyor 1 and a conveyor frame 2. A circulating conveying trough 3 is provided on one side of the bottom of the conveyor 1. A conveyor block 4 is slidably connected to the inner trough of the circulating conveying trough 3 via a transmission chain. A conveyor belt 5 is provided on one side of the top of the conveyor frame 2. Anti-fall plates 6 are welded to both sides of the top of the conveyor frame 2. A main rod 7 is welded to one end of the bottom of the conveyor block 4. Hook rods 8 are rotatably connected to the outer arcs on opposite sides of the main rod 7. A baffle 9 is welded to the bottom of the conveyor 1 at a position parallel to the hook rods 8. The main rod 7 drives the hook rods 8 to hang the pork. When the hook rods 8 pass the baffle 9, the baffle 9 blocks the hook rods 8, causing them to rotate. Afterwards, when the hook rods 8 move to the front end, the pork is unloaded by its own weight. The weight of the pork continues to drive the hook rod 8 to rotate until the front end faces downward. Then, the pork can be unhooked and unloaded by its own weight, reducing the manual operation required, improving production efficiency and reducing the amount of manual labor. The main rod 7 has a rotating groove 10 in the inner groove of the hook rod 8. A rotating block 11 is welded to one end of the hook rod 8 relative to the rotating groove 10. The rotating block 11 engages with the rotating groove 10 and is rotatably connected. The weight of the pork can drive the hook rod 8 to flip, thus achieving automatic and fast unloading, improving processing efficiency and reducing the amount of manual labor. The inner wall of the anti-fall plate 6 is equipped with a side roller belt 21 through the rotating roller. The side roller belt 21 allows the falling pork to move smoothly onto the conveyor belt 5, thereby achieving a better unloading and conveying effect.

[0030] In use, pork is processed and then hung upside down on hook rod 8. The chain in the circulating conveyor trough 3 driven by the motor drives the conveyor block 4 to move forward in the circulating conveyor trough 3. The main rod 7 and hook rod 8 suspend and convey the pork forward. The hook rod 8 is blocked by the screen of baffle 9, causing it to rotate. At this time, the rotating block 11 rotates in the rotating trough 10 to ensure stability. At this time, the pork cannot fall off and be unloaded because of the limitation of baffle 9. After the hook rod 8 moves out of the position of baffle 9, the weight of the pork causes the hook rod 8 to rotate downward. Then the tip of the hook rod 8 points downward, and the pork naturally slides down onto the conveyor belt 5 of the lower conveyor frame 2 for forward conveying or further processing.

[0031] In existing technologies, unloading pork is generally done manually, which is not only inefficient and labor-intensive, but also inevitably leads to hand injuries over a long period of time.

[0032] Example 2

[0033] Please see Figure 3 and Figure 5 Further improvements were made based on Example 1:

[0034] A rotating rod 12 is rotatably connected to the inner groove of the rotating trough 10. The rotating rod 12 is welded to the rotating block 11. A spring-loaded torsion spring 13 is fitted onto the rotating rod 12. The spring-loaded torsion spring 13 allows the hook rod 8 to automatically spring back to its original position after the pork is unloaded, thereby reducing the amount of resetting work, improving processing efficiency, and facilitating subsequent cyclic hanging. A semi-arc plate 15 is fixedly connected to one side of the outer arc wall of the rotating block 11. The semi-arc plate 15 is engaged with and rotatably connected to an annular groove 14. A stop block 16 is welded to the upper side of the inner groove of the annular groove 14. The rotation of the semi-arc plate 15 within the annular groove 14 ensures greater stability of the hook rod 8 during rotation and unloading. At the same time, the stop block 16 provides support to both ends of the semi-arc plate 15. By blocking the rotation, the hook rod 8 can be prevented from rotating excessively, thus improving the efficiency and stability of meat unloading. An arc-shaped groove 17 is formed on the inner wall of the annular groove 14. An arc-shaped rod 18 is welded to the inner wall of the arc-shaped groove 17. A sliding block 19 is engaged with and slidably connected to the arc-shaped groove 17. The arc-shaped rod 18 and the sliding block 19 pass through and are slidably connected. An arc-shaped spring 20 is welded between the sliding block 19 and the inner wall of the arc-shaped groove 17. As the sliding block 19 slides in the arc-shaped groove 17 and then the arc-shaped spring 20 rebounds, a certain damping sensation is generated when the semi-arc plate 15 rotates in the annular groove 14, further improving the stability of the hook rod 8 during the rotation and meat unloading process.

[0035] During the meat unloading process, the rotating block 11 rotates within the rotating groove 10, while the rotating rod 12 drives the return torsion spring 13 to rewind. Simultaneously, the semi-arc plate 15 on the outer side of the rotating block 11 rotates within the annular groove 14. The semi-arc plate 15 then pushes the sliding block 19 to slide on the arc rod 18 within the arc groove 17. The arc spring 20 provides a damping effect, preventing the rotating block 11 from driving the hook rod 8 to rotate too quickly, ensuring the stability of the meat unloading process. After the semi-arc plate 15 rotates to the desired position, it is blocked by the stop block 16, preventing the semi-arc plate 15 from rotating too much and reducing the possibility of unloading the pork due to excessive rotation. After unloading, when there is no weight on the hook rod 8, the return torsion spring 13 and the arc spring 20 cause the rotating block 11 to drive the hook rod 8 to reset for use, thereby improving the convenience and efficiency of the device.

[0036] Example 3

[0037] Please see Figure 4 Further improvements were made based on Example 1:

[0038] A side plate 22 is welded to the side wall of the conveyor frame 2 relative to the anti-fall plate 6. A groove 23 is provided on the side plate 22. A slider 25 is engaged and slidably connected in the groove 23. A slide rod 24 is slidably connected through the slider 25. The slide rod 24 is welded to the inner wall of the groove 23. A buffer rod 26 is rotatably provided between the slider 25 and the anti-fall plate 6. A buffer spring 27 is welded between the slider 25 and the inner wall of the groove 23. When the anti-fall plate 6 is impacted by the falling pork during unloading, it is supported by the buffer rod 26, which then pushes the slider 25 to slide in the groove 23 and slide through the slide rod 24. At this time, the buffer spring 27 contracts to buffer, thereby achieving better unloading protection, reducing the impact of falling pork, and ensuring the stability and efficiency of pork unloading.

[0039] Example 4

[0040] Please see Figure 6 Further improvements were made based on Example 1:

[0041] A mounting block 28 is inserted and plugged into the side wall of the conveyor frame 2 away from the conveyor 1. A slot 31 is opened on the outer wall of the conveyor frame 2 opposite to the mounting block 28. A plug rod 30 is engaged and plugged into the inner wall of the slot 31. The plug rod 30 is welded to the opposite side of the mounting block 28. A cleaning pad 29 that is attached to and scrapes off the conveyor belt 5 is attached to the inner side of the mounting block 28. During the unloading process, the pork inevitably leaves blood on the surface of the conveyor belt 5. If blood remains on the surface of the conveyor belt 5 for a long time, it will not only easily cause pollution and reduce the safety of pork production and transportation, but also easily cause corrosion of the equipment. Therefore, through the detachable and replaceable cleaning structure, the blood on the surface of the conveyor belt 5 can be treated in time after transportation, reducing the pollution caused by blood and affecting the safety of pork processing. Furthermore, it keeps the surface of the conveyor belt 5 and the conveyor frame 2 clean, reduces corrosion of the equipment surface, and extends the service life of the equipment.
