Technical Field

[0001] The utility model relates to the field of poultry cutting, in particular to a poultry leg cutting device. Background Art

[0002] During the poultry cut-up process on the assembly line, fixed hooks (such as those described in utility model patent No. CN219679639U) are attached to the bird's legs. The hooks move along the assembly line, driving the bird's movements. Before the thigh and shank are cut, the bird's trunk has already been cut, leaving only the legs hanging from the fixed hooks.

[0003] The existing cutting process requires separating chicken legs into thighs and shanks (knee drumsticks). Currently, a cutting knife is used to directly cut the knee cartilage between the thighs and shanks to separate the thighs and shanks. However, the current cutting device directly separates the thighs and shanks without separating the knee cartilage between the thighs and shanks. This prevents the knee cartilage from being cut separately, resulting in poor utilization and reduced production returns. Utility Model Content

[0031] Furthermore, the second cutter 44 includes a first substrate 441 and a first cutting plate 442. The first substrate 441 is fixedly connected to the cutting frame 41. The front side of the first substrate 441 is integrally formed with the first cutting plate 442. The first cutting plate 442 is bent upward. A first inclined blade 443 and a first horizontal blade 444 are formed on the left and right sides of the upper end of the first cutting plate 442.

[0032] Furthermore, a second slit 440 is formed between the first horizontal edge 444 and the first cutter 43 . The right side of the second slit 440 is connected to the third slit 450 . The second slit 440 has the same width from left to right and from top to bottom.

[0033] Furthermore, a first gap 430 is formed between the first inclined blade 443 and the first cutter 43 . The first gap 430 gradually narrows from left to right, and the right side of the first gap 430 is connected to the second gap 440 .

[0034] Furthermore, the third cutter 45 includes a second base plate 451 and a second cutting plate 452. The second base plate 451 is fixedly connected to the cutting frame 41. The front side of the second base plate 451 and the second cutting plate 452 are integrally formed. The front side of the second cutting plate 452 is formed with a second horizontal blade 454.

[0035] The third inclined edge 455 is formed on the second substrate 451 and is located on the left side of the second horizontal edge 454 .

[0036] Furthermore, the second cutting plate 452 is bent upward, and the angle between the second cutting plate 452 and the second base plate 451 is 166° to 176°. When cutting chicken legs, the upwardly bent second cutting plate 452 can adapt to the inclined connection between the thigh and the calf.

[0037] Preferably, the included angle between the second cutting plate 452 and the second base plate 451 is 171°.

[0038] Furthermore, a third inclined edge 455 is formed on the front side of the second cutting plate 452 , and the third inclined edge 455 is located between the third inclined edge 455 and the second horizontal edge 454 .

[0039] Furthermore, it also includes a positioning rod 42 , which is fixedly connected to the cutting frame 41 , and the positioning rod 42 is located behind the first horizontal blade 444 and the third inclined blade 455 .

[0040] Furthermore, the second cutter 44 is located below the first cutter 43 and the third cutter 45 .

[0041] Working principle:

[0042] When working, the fixed hook drives the chicken leg to move from left to right. The movement direction of the chicken leg is as follows: Figure 4 Indicated by the hollow arrow.

[0043] The outer side of the calf (i.e., the outer side of the inward bend of the chicken leg) contacts and slides along the positioning rod 42, which positions the chicken leg. The cutting blade 434 cuts below the knee cartilage, severing the skin and flesh below the knee cartilage to form an incision. The first blunt edge 435 of the lifting plate 432 then lifts the skin and flesh above the incision upward until they extend above the knee cartilage. The skin and flesh above the incision are then held in place above the first blunt edge 435 of the retaining plate 433, thereby keeping the knee cartilage exposed.

[0044] As the chicken leg continues to move to the right, the knee cartilage enters the first slit 430, and the inclined first inclined blade 443 cuts into the chicken leg and gradually deepens the depth of the cut. After that, the knee cartilage enters the second slit 440, and the horizontal first horizontal blade 444 completely cuts the incision below, and the first blunt blade 435 and the first horizontal blade 444 position the knee cartilage. The knee cartilage enters the third slit 450, and as the slit narrows, the first horizontal blade 444 and the third inclined blade 455 completely cut the knee cartilage off the chicken leg. Because during the process of cutting the knee cartilage, the skin and meat above the incision are limited by the retaining plate 433 and the second base plate 451, above them, the cut knee cartilage is not connected to the skin and meat. Among them, the cut knee cartilage falls into the collection device from the hole of the second cutter 44 (not shown in the figure).

[0045] As the chicken leg moves, the second cutting plate 452 enters between the cuts on the thigh and the calf, and continues to longitudinally cut the chicken between the thigh and the calf. After the cutting is completed, the chicken leg leaves the pre-cutting device along with the fixed hook. It should be noted that the cutting is complete, which means that the thigh and the calf are completely separated or incompletely cut according to the needs of the product.

[0046] The present invention is described above by way of examples, but the present invention is not limited to the above specific embodiments. Any changes or modifications based on the present invention fall within the scope of protection claimed by the present invention.
