Description

TECHNICAL FIELD

[0001] The utility model relates to the field of meat processing, more specifically, it relates to a circulating push mechanism for pig scalding. BACKGROUND

[0002] In a pig slaughterhouse, the slaughtering and processing of live pigs is a highly automated and standardized process, which includes the process of scalding and unhairing live pigs. During the scalding process, live pigs are conveyed to a scalding tank for further immersion treatment. The scalding tank is a container filled with hot water, with water temperature usually controlled between 70-90 degrees Celsius to ensure that the pig hair can be effectively removed while avoiding adverse effects on the pork. The traditional scalding method requires manual pulling of live pigs through the scalding tank. The speed and rhythm of manual pulling are difficult to maintain consistent, resulting in the inability to accurately control the residence time of live pigs in the scalding tank. Too short residence time may not completely remove the pig hair, while too long residence time may cause the pork surface to overcook, affecting the taste. Due to the instability of manual pulling, the posture and position of live pigs in the scalding tank are also difficult to maintain consistent. This may result in some pig carcasses not being fully exposed to hot water, thereby affecting the quality of scalding. SUMMARY

[0024] Example:

[0025] A circulating pushing mechanism 3 for scalding pig hair is disclosed. The pushing mechanism 3 is used in conjunction with a scalding tank 1 and is positioned above the scalding tank 1. The pushing mechanism 3 includes a support frame 5, a pushing component, and a driving device; the support frame 5 is positioned above the pushing mechanism 3. Optionally, the support frame 5 is directly connected to the scalding tank 1; alternatively, the support frame 5 is suspended above the scalding tank 1. The pushing component includes a sprocket and a pushing chain 33; the sprocket includes a first sprocket 31 and a second sprocket 32; the first sprocket 31 and the second sprocket 32 ​​are connected to the support frame 5 via sprocket bearings; the first sprocket 31 and the second sprocket 32 ​​are connected via the pushing chain 33; the driving device is used to drive the first sprocket 31 to rotate; multiple pushing frames 2 are provided on the pushing chain 33; the multiple pushing frames 2 are evenly distributed on the pushing chain 33. The pusher frame 2 includes a frame surface and mounting rods 23; the frame surface includes a frame 21 and multiple connecting rods 22 disposed within the frame 21; the frame 21 is connected to the mounting rods 23; the mounting rods 23 are connected to the pusher chain 33. The scalding tank 1 is trough-shaped and includes an inlet end and an outlet end. Hot water is contained in the scalding tank 1. Under external force, the pig moves from the inlet end to the outlet end, completing the scalding of the pig hair, facilitating the next step of hair removal. An inclined surface is provided at the inlet end of the scalding tank 1, extending from the bottom of the scalding tank 1. This inclined surface reduces water splashing when the pig is transferred to the scalding tank 1. After the drive device is started, the first sprocket 31, in conjunction with the second sprocket 32, drives the pusher chain 33 to circulate on the support frame 5. This, in turn, causes the pusher frame 2 to circulate on the support frame 5. The first sprocket 31 is located at the inlet end of the scalding tank 1, and the second sprocket 32 ​​is located at the outlet end of the scalding tank 1. When the pusher frame 2 moves into the scalding tank 1, part of the pusher frame 2 is submerged in the hot water and moves from the inlet end to the outlet end under the drive of the pusher chain. After the pig enters the scalding tank 1, it slides down the slope between the two pusher frames 2. The pusher frame 2 pushes the pig forward along a predetermined path in the scalding tank 1 until the scalding process is completed. The entire process realizes the automatic and continuous movement of the pig in the scalding tank 1. Since the speed of the pusher frame 2 is constant, the time the pig stays in the scalding tank 1 is consistent, and the scalding effect is also consistent. At the same time, the device significantly improves the production efficiency of scalding and hair removal, reduces manual intervention, and reduces labor intensity. The design of the frame 21 and the connecting rod 22 reduces the resistance of the pusher frame 2 moving in the hot water.

[0026] Preferably, the pusher frame 2 is further provided with a buffer 24; the buffer 24 includes a connecting part 242; the connecting part 242 is connected to two support legs 241 on both sides, forming a U-shaped structure; the bottoms of the support legs 241 are close to each other; the bottoms of the support legs 241 are connected to the frame 21. During the process of pushing the pig in the scalding tank 1, the buffer 24 can play a buffering role, reducing the force between the pusher frame 2 and the pusher chain 33, and avoiding damage to the pusher frame 2.

[0027] Preferably, the pushing mechanism 3 includes a pushing shaft and two pushing components; the pushing shaft includes a first pushing shaft 341 and a second pushing shaft 342, which are respectively connected to the support frame 5 via sprocket bearings; the two ends of the first pushing shaft 341 are respectively connected to the first sprockets 31 of the two pushing components; the two ends of the second pushing shaft 342 are respectively connected to the second sprockets 32 of the two pushing components; the pushing mechanism 3 also includes a transmission component; the driving device drives the first pushing shaft 341 to rotate through the transmission component, thereby driving the first sprockets 31 at both ends of the first pushing shaft 341 to rotate, thus enabling the two pushing components to move synchronously in a cyclic manner. In this embodiment, a pushing frame 2 is connected to the pushing chains 33 of the two pushing components respectively, so that the force on the pushing frame 2 is more balanced during the movement.

[0028] Furthermore, both the first sprocket 31 and the second sprocket 32 ​​are connected to the support frame 5 via a tensioning assembly 37. The tensioning assembly 37 includes an upper slide rail 371, a lower slide rail 372, a slider seat 374, and an adjusting screw 373. The upper slide rail 371 and the lower slide rail 372 are fixedly connected to the support frame 5. The upper slide rail 371 and the lower slide rail 372 are provided with raised slide tracks opposite each other. The slider seat 374 is provided with a concave slide groove that mates with the slide track. The outer ring of the sprocket bearing is connected to the slider. The inner ring of the sprocket bearing is connected to the push shaft. The support frame 5 is provided with a threaded hole. The adjusting screw 373 mates with the threaded hole. The top of the adjusting screw 373 abuts against the slider seat 374. In use, the slider seat 374 is placed between the upper slide rail 371 and the lower slide rail 372, with the slide track and slide groove mate. The adjusting screw 373 is located inside the push chain 33. When adjusting the adjusting screw 373, its top abuts against the slider seat 374, thus fixing the position of the slider seat 374 in conjunction with the push chain 33. During maintenance, adjusting the adjusting screw 373 away from the slider seat 374 allows the push chain 33 to change from a tensioned state to a slack state, facilitating replacement of the push chain 33. Proper tension adjustment can reduce wear between the chain and sprocket, extend the service life of the equipment, and reduce the failure rate. Preferably, the tensioning assembly 37 also includes a positioning plate 375, which connects the upper slide rail 371 and the lower slide rail 372. The positioning plate 375 has a positioning hole; the adjusting screw 373 passes through the positioning hole and abuts against the slider seat 374. The positioning hole can fix the force direction of the adjusting screw 373, better securing the slider seat 374.

[0029] Optionally, the push chain 33 includes multiple mounting links; each mounting link includes a mounting side plate; the mounting rod 23 is connected to the mounting side plate 331; and the mounting links are evenly distributed on the push chain 33.

[0030] Preferably, the drive device includes a motor 51 and a reducer 52; the reducer includes an input shaft and a first output shaft; the motor is connected to the input shaft; the first output shaft is connected to a first push shaft 341 via a transmission assembly; the transmission assembly includes a drive wheel 38, a driven wheel 35, and a drive chain; the drive wheel 38 is mounted on the first output shaft; the driven wheel 35 is mounted on the first push shaft 341; the drive wheel 38 and the driven wheel 35 are driven by the drive chain. The transmission assembly also includes an adjustment component; the adjustment component includes an adjustment seat 361, on which a tension wheel 362 is provided; the adjustment seat 361 also has two fixing slots 363; the fixing slots 363 are strip-shaped; the support frame 5 also has mounting holes corresponding to the fixing slots 363; the mounting holes and the fixing slots 363 are connected by mounting bolts; the tension wheel 362 cooperates with the drive chain. The strip-shaped fixing groove 363 can adjust the position of the seat 361 on the support frame 5, change the positional relationship between the tension wheel 362 and the drive chain, and thus make the drive chain in a tensioned or slack state for easy replacement.

[0031] In one possible embodiment, the pushing mechanism 3 further includes a swing mechanism 4, which includes a front roller 41, a rear roller 42, and a swing assembly. Both ends of the front roller 41 and the rear roller 42 are provided with rollers 43 for moving on the hot water tank 1. The front roller 41 and the rear roller 42 are mounted on a support frame 5. The swing assembly includes a swing arm 44, a swing connecting rod 45, and a connecting rod fixing seat 46. One end of the swing arm 44 is connected to a driving device, which drives the swing arm 44 to rotate. The other end of the swing arm 44 is hinged to the swing connecting rod 45. Both ends of the swing connecting rod 45 are hinged to the swing arm 44 and the connecting rod fixing seat 46, respectively. A crossbeam 47 is provided on the hot water tank 1. The connecting rod fixing seat 46 is mounted on the crossbeam 47. The driving device is mounted on the support frame 5. The driving device drives the swing arm 44 to perform circular motion, causing the support frame 5 to reciprocate above the hot water tank 1. As the pigs move towards the outlet, they swing back and forth between the two pushers 2, creating flow between the water and the pigs, which allows for better scalding of the pig hair. At the same time, the buffer 24, in conjunction with the pigs, allows them to roll around in the scalding tank 1 to a certain extent, which also makes the scalding more even.

[0032] Preferably, the hot water tank 1 is provided with a roller 43 groove; the roller 43 is disposed in the roller 43 groove. This prevents derailment during swaying and increases safety.

[0033] Preferably, the reducer includes a second output shaft; the second output shaft is connected to the swing arm 44. The reducer drives two pushing components and a swinging component to move simultaneously via a motor, which reduces the complexity of the equipment and saves energy.

[0034] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
