Description

Technical field:

[0001] The utility model relates to the technical field of poultry slaughtering, in particular to a crop opening mechanism. Background technology:

[0002] As people's requirements for the quality of poultry products and hygiene and epidemic prevention become increasingly higher, chickens are no longer supplied to the market simply as live poultry, but are slaughtered, divided and packaged in batches by production companies and then put on the market as semi-finished products. This method can effectively improve the return rate of breeding companies.

[0003] Currently, in poultry slaughterhouses, chickens are slaughtered by slitting their throats to bleed them, followed by depilation and evisceration. However, crop opening is the first step in the evisceration process. Domestically, non-white-feathered chickens are slaughtered manually using scissors or knives to cut the esophagus above the crop, allowing the viscera to be pulled out from the body for further processing. In a poultry slaughtering line, with a production rate of 4,000-7,000 birds per hour, three to five workers are required. Each worker performs tens of thousands of repetitive cuts per day, resulting in high workload and inconsistent crop opening quality. Skilled operators are also required, which can lead to occupational diseases and high labor costs. Companies are urgently seeking automated alternatives to poultry slaughtering to achieve fully automated poultry slaughtering and improve production efficiency.

[0029] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0030] See Figure 1-12As shown, a crop opening mechanism 1 includes: a first Y-axis driving module 16, a first profiling fixture 5 installed on the first Y-axis driving module 16 and a scissors module 6 located next to the first profiling fixture 5 and linked to it, a second Y-axis driving module 17 located next to the first Y-axis driving module 16, and a second profiling fixture 7 installed on the second Y-axis driving module 17 and corresponding to the first profiling fixture 5. The first profiling fixture 5 and the second profiling fixture 7 constitute a profiling fixture, and the opposite surfaces of the first profiling fixture 5 and the second profiling fixture 7 are respectively provided with a first clamping groove 50 and a second clamping groove 70; a first profiling fixture 5 is provided with a guide block 8 that can slide elastically, and the first profiling fixture 5 or the second profiling fixture 7 is provided with a humanoid finger 9. During operation, the first Y-axis drive module 16 and the second Y-axis drive module 17 respectively drive the first profiling fixture 5 and the second profiling fixture 7 to precisely approach each other. The first clamping groove 50 of the first profiling fixture 5 and the second clamping groove 70 of the second profiling fixture 7 respectively clamp the dorsal and ventral sides of the base of the poultry's neck, thereby ensuring that the poultry does not shake during transportation on the conveyor chain, achieving a positioning effect. At the same time, the elastically slidable guide block 8 contacts the base of the poultry's neck, allowing the poultry suspended on the conveyor chain to adjust its posture, facilitating effective shearing of the esophagus later. The base of the poultry's neck is generally large, and this varies greatly among different poultry species. The addition of a movable guide block allows for alignment of the posture of the necks of poultry of varying sizes. Furthermore, the esophagus at the upper end of the crop is separated and squeezed out of the poultry's neck using humanoid fingers, thereby improving the success rate of the subsequent shearing module when shearing the esophagus at the upper end of the crop and improving the shearing effect, thereby preventing the shearing from being too large. Finally, the scissor module 6 pierces the skin at the poultry's neck to cut the esophagus above the crop inside the skin, allowing for later removal of the internal organs. In other words, the intelligent, fully automated, unmanned process of this utility model implements "crop opening," a crucial pre-process in the poultry slaughtering industry. This overturns the traditional method of manually shearing the crop and esophagus with multiple handheld scissors, creating a new paradigm for the intelligent upgrade of the poultry slaughtering industry, greatly improving production efficiency while ensuring the quality of crop opening and severing the esophagus above the crop. It also contributes to improved food production safety and efficiency, creating significant economic and social value.

[0031] In this embodiment, the poultry is chicken.

[0032] The crop opening mechanism 1 also includes a base 11, a first upright pole 13 mounted on one side of the base 11 via a first Z-axis drive module 12, and a second upright pole 15 mounted on the other side of the base 11 and opposite to the first upright pole 13 via a second Z-axis drive module 14. The first Y-axis drive module 16 is mounted on the upper end of the first upright pole 13, and the second Y-axis drive module 17 is mounted on the upper end of the second upright pole 15. Both the first Z-axis drive module 12 and the first Z-axis drive module 14 are driven by servo motors.

[0033] When the crop opening mechanism 1 is working, the first Z-axis driving module 12 and the second Z-axis driving module 14 drive the first profiling fixture 5 and the second profiling fixture 7 to rise to corresponding heights to meet different crop opening requirements.

[0034] In this embodiment, the first clamping groove 50 of the first contouring fixture 5 and the second clamping groove 70 of the second contouring fixture 7 are contoured (to the shape of a chicken's neck), accommodating different types of chickens (different breeds have different neck and body sizes). The humanoid finger-like design allows the esophagus and trachea of different chickens to be squeezed out of the neck, separating them from the tibia and facilitating shearing.

[0035] The front end of the first profiling fixture 5 is provided with a first guiding seat 51 and a second guiding seat 52 distributed in an eight-shaped manner on the outside of the first clamping groove 50, and the first guiding seat 51 and the second guiding seat 52 respectively have a first guiding groove 511 and a second guiding groove 521. The front end of the second profiling fixture 7 is provided with a first guiding piece 71 and a second guiding piece 72 distributed in an eight-shaped manner on the outside of the second clamping groove 70. When the first profiling fixture 5 and the second profiling fixture 7 are relatively close to each other, the first guiding piece 71 and the second guiding piece 72 are respectively inserted into the first guiding groove 511 and the second guiding groove 521, thereby ensuring that the first profiling fixture 5 and the second profiling fixture 7 can be guided close together to ensure the purpose of clamping the necks of the poultry with each other. Its operation is smoother and more precise, and jamming is avoided.

[0036] The lower end of the first profiling fixture 5 is provided with a first slide groove 53, and a first limit block 54 is also provided in the first slide groove 53; the outer side of the guide block 8 is provided with a guide groove 80 for supporting the root of the poultry's neck; the middle part of the guide block 8 is provided with a first strip slide hole 81, and the guide block 8 is installed in the first slide groove 53, and the first strip slide hole 81 is sleeved on the outer periphery of the first limit block 54, and a first spring 82 is provided between the first strip slide hole 81 and the first limit block 54, and the guide block 8 protrudes outside the first profiling fixture 5 under the elastic force of the first spring 82, and the lower end of the first profiling fixture 5 is provided with a first cover plate 55, and the first cover plate 55 covers part of the first slide groove 53, the first limit block 54 and the guide block 8 to ensure the stability of the assembly structure. During operation, the guide block 8 of the first profiling fixture 5 protrudes from the outside of the first profiling fixture 5 due to the elastic force of the first spring 82. When it contacts the base of the poultry's neck, the guide block 8 engages the base of the neck through the guide groove 80, effectively guiding the poultry and adjusting its posture. If the base of the poultry's neck is large, the guide block 8 is pushed inward by the first spring 82 upon contact, effectively guiding the poultry's neck and adjusting its posture. This allows the guide block 8 to effectively guide and adjust the posture of poultry with larger necks, thus providing a wide range of applications. Furthermore, because the guide block 8 is mounted within the first chute 53 and the first strip-shaped slide hole 81 is positioned around the periphery of the first stop block 54, the resulting sliding structure slides smoothly and is structurally stable. A fifth limiting groove is provided in the first limiting block 54 , and one end of the first spring 82 is embedded in the fifth limiting groove to ensure the stability of the assembly structure.

[0037] The humanoid finger 9 includes a transmission striker 92 which is elastically slidable and is inserted into the first profiling fixture 5 through a second spring 91, a transmission rod 93 which is slidably inserted into the second profiling fixture 7 and adapted to the transmission striker 92 and partially extends out of the second profiling fixture 7, a finger rod 94 which is rotatably installed in the second profiling fixture 7, and a finger 95 which is movably installed at the front end of the finger rod 94 and extends out of the second profiling fixture 7, a third spring 96 which is arranged between the finger rod 94 and the finger 95, a fourth spring 97 which is arranged between the finger rod 94 and the second profiling fixture 7, and a transmission gear 98 which is rotatably installed in the second profiling fixture 7. The rear end of the transmission rod 93 is provided with a plurality of continuously distributed first teeth 931, and the rear end of the finger rod 94 is provided with a plurality of continuously distributed second teeth 941. The first teeth 931 of the transmission rod 93 and the second teeth 941 of the finger rod 94 are both engaged with the transmission gear 98. The transmission rod 93 is linked to the finger rod 94; during operation, when the first Y-axis driving module 16 and the second Y-axis driving module 17 respectively drive the first profiling clamp 5 and the second profiling clamp 7 to move closer to each other, thereby driving the first profiling clamp 5 and the second profiling clamp 7 to capture and clamp the neck of the poultry, at this time, the transmission striker 92 contacts the transmission rod 93 and pushes each other to drive the transmission rod 93 to move from outside to inside. While the transmission rod 93 moves, it drives the finger rod 94 and the finger 95 at its end to move from inside to outside through the transmission gear 98, so that the finger 95 moves closely against the outer skin of the poultry neck, thereby separating and squeezing the esophagus at the upper end of the crop from the neck of the poultry; when the first profiling clamp 5 and the second profiling clamp 7 are separated from each other, the transmission striker 92 is reset by the second spring 91, and the finger rod 94 is reset by the fourth spring 97 to move from outside to inside, and then the transmission rod 93 is driven from inside to outside to reset through the transmission gear 98. In addition, since a third spring 96 is provided between the finger rod 94 and the finger 95, and the finger rod 94 and the finger 95 are movably connected, that is, the third spring 96 provides elasticity for the finger 95 relative to the finger rod 94, so that the finger 95 can elastically float relative to the finger rod 94, and then when the finger 95 moves close to the outer skin of the poultry neck, it is a flexible contact, which can better separate and extrude the esophagus at the upper end of the crop from the poultry neck. At the same time, this structure can be applied to poultry necks of different sizes for esophagus separation and extrusion.

[0038] Among them, a first stroke limit piece 73 is provided in the second contour clamp 7, and a second slide groove 942 is provided on the finger rod 94. The first stroke limit piece 73 extends into the second slide groove 942, which has a guiding sliding function, and the two ends of the fourth spring 97 are respectively pressed and contacted with the inner wall of the second slide groove 942 and the first stroke limit piece 73, so that the fourth spring 97 provides an elastic thrust from the outside to the inside for the finger rod 94.

[0039] Among them, a second stroke limit piece 74 is provided in the second profiling clamp 7, and a third slide groove 933 is provided on the transmission rod 93. The second stroke limit piece 74 extends into the third slide groove 933, which has a guiding sliding function. The two ends of the fifth spring 99 are respectively pressed and contacted with the inner wall of the third slide groove 933 and the second stroke limit piece 74, so that the fifth spring 99 provides an elastic thrust from the inside to the outside for the transmission rod 93, and drives the transmission rod 93 to protrude outside the second profiling clamp 7.

[0040] The assembly structure of the finger rod 94 and the finger 95 is as follows: the finger rod 94 is provided with a circular movable groove 943 protruding outward and a first limiting groove 944 located next to the circular movable groove 943; the rear end of the finger 95 is provided with a circular convex portion 951 adapted to the circular movable groove 943 and a second limiting groove 952 located next to the circular convex portion 951; the circular movable groove 943 and the circular convex portion 951 are arranged on each other and can rotate relative to each other, and the two ends of the third spring 96 are respectively embedded in the first limiting groove 944 and the second limiting groove 952, to ensure that the third spring 96 is stably installed on the finger rod 94 and the finger 95, and form a stable floating assembly structure.

[0041] The second profiling fixture 7 has a bottom cover 700 at its lower end, and the finger rod 94 , the finger head 95 , the transmission gear 98 and the transmission rod 93 are all installed in the bottom cover 700 .

[0042] The end face of the transmission rod 93 is provided with a striker groove 932 adapted to the transmission striker 92. When the transmission rod 93 contacts the transmission striker 92, the transmission striker 92 is inserted into the striker groove 932, thereby ensuring that the transmission rod 93 and the transmission striker 92 form a stable contact and have a guiding effect, so that the transmission rod 93 can be better driven to move stably.

[0043] The outside of the finger 95 is provided with a plurality of arc-shaped third teeth 950, which can more stably separate and squeeze out the esophagus at the upper end of the crop from the neck of the poultry.

[0044] The scissors module 6 includes a cylinder 61 mounted on the outside of the first profiling fixture 5 in a manner that can adjust the front and rear positions, a bracket 62 mounted on the slide 611 outside the cylinder 61, a sliding seat 63 mounted in a slidable manner in the bracket 62, a sixth spring 60 mounted between the sliding seat 63 and the bracket 62, a first L-shaped blade 65 and a second L-shaped blade 66 mounted on the front end of the sliding seat 63 in a rotatable manner by a rotating shaft screw 64, a linkage block 67 fixed to the rear end of the sliding seat 63, and a spring 68 mounted on the cylinder 61. The guide plate 68 at the rear end and the pull rod screw 69 that passes through the guide plate 68 and is connected to the linkage block 67 in a manner that the relative position can be adjusted in the front and rear directions, the first shaft rod 621 and the second shaft rod 622 are respectively provided on both sides of the front end of the bracket 62, and the outer sides of the first L-shaped blade 65 and the second L-shaped blade 66 (i.e., the handle part) are respectively provided with a first U-shaped opening 651 and a second U-shaped opening 661, the first U-shaped opening 651 is sleeved on the outer periphery of the first shaft rod 621, and the second U-shaped opening 661 is sleeved on the outer periphery of the second shaft rod 622. The sliding seat 63 is ejected outward (i.e., forward) relative to the bracket 62 under the elastic force of the sixth spring 60. After the slide 611 outside the cylinder 61 drives the bracket 62 backward, the sliding seat 63 is pulled by the pull rod screw 69 and cannot move. However, the first L-shaped blade 65 and the second L-shaped blade 66 can rotate relative to the front end of the sliding seat 63. At this time, as the bracket 62 moves backward, the first U-shaped opening 651 of the first L-shaped blade 65 and the second U-shaped opening 661 of the second L-shaped blade 66 are driven backward. The first L-shaped blade 65 and the second L-shaped blade 66 are relatively open due to the restraining action of the first U-shaped opening 651 and the second U-shaped opening 661 and the first and second shafts 621 and 622. Similarly, when the slide 611 outside the cylinder 61 drives the bracket 62 forward, the first L-shaped blade 65 and the second L-shaped blade 66 close together to achieve the shearing operation. The function of the sixth spring 60 is to drive the sliding seat 63 to extend forward, that is, the sliding seat 63 can float back and forth relative to the bracket 62.

[0045] The pull rod screw 69 is threadedly connected to the guide plate 68, allowing for adjustment of their relative position. Alternatively, a nut 681 is provided within the guide plate 68, which is screwed onto the pull rod screw 69 to allow for adjustment of their relative position. Adjusting the relative position of the pull rod screw 69 and the guide plate 68 further adjusts the position of the linkage block 67 and the sliding seat 63 relative to the bracket 62, thereby adjusting the opening size and cutting depth of the first and second L-shaped blades 65 and 66 to meet different usage requirements.

[0046] The linkage block 67 is provided with a thread groove, and the end of the pull rod screw 69 is provided with a thread section, which is spirally installed to be connected with the thread groove.

[0047] The cylinder 61 is provided with a threaded groove 610 on the outside, and the first profiling fixture 5 is provided with a strip-shaped hole 501 on the outside. A first screw passes through the strip-shaped hole 501 and is screwed into the threaded groove 610, thereby ensuring that the scissors module 6 is stably mounted on the outside of the first profiling fixture 5. When the relative position needs to be adjusted, the first screw is loosened and moved back and forth through the strip-shaped hole 501 to adjust the front-to-back position of the cylinder 61 relative to the first profiling fixture 5. After the adjustment is completed, the first screw is tightened, making the operation extremely convenient.

[0048] A crossbar 620 is provided in the middle of the bracket 62. The sliding seat 63 is U-shaped and fits around the crossbar 620, allowing it to slide forward and backward. The linkage block 67 is fixed to the rear side of the sliding seat 63 and surrounds the crossbar 620. One end of the sixth spring 60 is inserted into the transverse groove 603 of the crossbar 620. The other end of the sixth spring 60 is inserted into the sliding seat 63.

[0049] The first baffle 601 and the second baffle 602 are respectively installed on the upper ends of the first shaft 621 and the second shaft 622 by the third screw and the fourth screw, and the outer side (i.e., the handle part) lower surface of the first L-shaped blade 65 and the second L-shaped blade 66 is attached to the upper surface of the front end of the sliding seat 63, and the first baffle 601 and the second baffle 602 are respectively placed on the outer side (i.e., the handle part) upper surface of the first L-shaped blade 65 and the second L-shaped blade 66, so as to prevent the first L-shaped blade 65 and the second L-shaped blade 66 from falling out relative to the first shaft 621 and the second shaft 622, thereby ensuring the stability and quality of the assembly structure.

[0050] In summary, during operation, the first Y-axis drive module 16 and the second Y-axis drive module 17 respectively drive the first profiling fixture 5 and the second profiling fixture 7 to precisely approach each other. The first clamping groove 50 of the first profiling fixture 5 and the second clamping groove 70 of the second profiling fixture 7 respectively clamp the dorsal and ventral sides of the base of the poultry's neck, thereby ensuring that the poultry does not shake during transportation on the conveyor chain, achieving a positioning effect. At the same time, the elastically slidable guide block 8 contacts the base of the poultry's neck, allowing the poultry suspended on the conveyor chain to adjust its posture, facilitating effective shearing of the esophagus later. The base of the poultry's neck is generally large, and varies greatly among different poultry species. The addition of a movable guide block allows for alignment of the posture of the necks of poultry of varying sizes. Furthermore, the esophagus at the upper end of the crop is separated and squeezed out of the poultry's neck using humanoid fingers, thereby improving the success rate of the subsequent scissor module in shearing the esophagus at the upper end of the crop and improving the quality of the shear cut, thereby preventing the cut from being too large. Finally, the scissor module 6 pierces the skin at the poultry's neck to cut the esophagus above the crop inside the skin, allowing for later removal of the internal organs. In other words, the intelligent, fully automated, unmanned process of this utility model implements "crop opening," a crucial pre-process in the poultry slaughtering industry. This overturns the traditional method of manually shearing the crop and esophagus with multiple handheld scissors, creating a new paradigm for the intelligent upgrade of the poultry slaughtering industry, greatly improving production efficiency while ensuring the quality of crop opening and severing the esophagus above the crop. It also contributes to improved food production safety and efficiency, creating significant economic and social value.
