[0002] When poultry processing companies trim poultry clavicles (such as duck clavicles) and their accessories such as fat and trachea, they mostly do it manually. This is not only inefficient, but also requires a large number of workers. In addition, hand injuries are prone to occur during large-scale processing, which greatly increases the company's processing costs and has extremely low safety. Summary of the invention

[0003] The purpose of the present invention is to provide an automatic poultry clavicle trimming device and a trimming method thereof, which can replace manual work to complete the separation and processing of poultry clavicle and its accessories such as grease, has high safety, and can also improve work efficiency and save processing costs.

[0004] The technical solution of the present invention is as follows:

[0005] The invention discloses an automatic poultry clavicle trimming device, which is used to replace manual work to trim the fat, trachea, fascia and other attachments on the poultry clavicle (such as duck clavicle). The structure of the clavicle is introduced below. The clavicle includes cartilage and the clavicle main body on both sides of its front and the cartilage protrusion in the middle of the back. Usually, there are some fat attachments on the clavicle main body on both sides of the clavicle and between the clavicle main body and the cartilage on both sides. In addition, there are attachments such as trachea or fascia between the clavicle main body and the cartilage on both sides of some clavicles. The above-mentioned trimming device is introduced below.

[0006] The trimming device comprises a frame and a conveying unit arranged thereon, and a trimming unit arranged on a conveying path of the conveying unit, the conveying unit comprises a pushing part and a loading part, a pressing part is arranged above the loading part, the pushing part is arranged to be able to push the clavicle to move between the loading part and the pressing part, the loading part comprises a straight bearing section, the straight bearing section comprises two bearing members arranged opposite to each other with a gap, the trimming unit comprises a cutting part rotatably arranged between the two bearing members, the clavicle main bodies on both sides of the clavicle can be straddled on the two bearing members, the cartilage of the clavicle protrudes upward, and the cutting part is arranged to be able to cut off the tracheal fascia attachment between the cartilage and the two clavicle main bodies, and is also arranged to be able to push off the cut tracheal fascia attachment, and in this process, part of the grease attachment between the cartilage and the two clavicle main bodies can also be pushed off;

[0007] Furthermore, the loading section also includes a supporting section parallel to the straight bearing section, the supporting section includes a supporting plate with an installation opening in the middle, the trimming unit also includes an oiling section arranged in the installation opening, and the oiling section is configured to be able to wipe off the grease accessories on the clavicle, an accessory collecting device is provided below the cutting section and the oiling section, the accessory collecting device is used to collect the accessories trimmed by the cutting section and the oiling section, and a discharge chute is also provided at the end of the supporting plate, and the trimmed clavicle slides into the discharge chute from the end of the supporting plate under the push of the pushing section, thereby completing the discharge of the finished product.

[0008] As an implementation method, for the setting of the oiling part, the supporting plate includes a first plate and a second plate which are arranged in sequence along the clavicle conveying direction, the oiling part includes two side oiling parts and a middle oiling part which are respectively arranged in the mounting holes of the first plate and the second plate, the two side oiling parts include a partition rod and first rotating screw groups on both sides thereof, the two clavicle main bodies can respectively enter the two first rotating screw groups to complete the oiling under the guidance of the partition rod, and the middle oiling part is configured to complete the fine wiping work of the remaining accessories between the cartilage and the two clavicle main bodies.

[0009] Furthermore, the middle greasing portion includes a second rotating screw group arranged along the conveying path, and when the clavicle passes through the second rotating screw group, the remaining grease attachment between the upper cartilage and the clavicle body is wiped off.

[0010] Among them, the structure and working principle of the first rotating screw group and the second rotating screw group can be the same as the spiral screw group shown in patent application number CN202221645560.9, which will not be repeated here.

[0011] In order to more thoroughly erase the attachments between the cartilage and the clavicle body, the second pallet includes an inclined section and a horizontal section which are arranged in sequence. The first pallet is arranged horizontally, and the upper side of the horizontal section of the second pallet is flush with the upper side of the first pallet. The inclined section of the second pallet is inclined upward to point in the conveying direction, and is arranged at an angle to the second rotating screw group. This arrangement makes the head end of the second pallet lower than the end of the first pallet, and the head end of the second rotating screw group is higher than the upper side of the second pallet, so that the area between the clavicle cartilage and the clavicle bodies on both sides is closer to the head end of the second rotating screw group. This allows the attachments in this area to be more accurately and forcefully erased when passing through the second rotating screw group. Because the distance is closer, the friction force, extrusion force and other effects of the second rotating screw group on this part of the attachment are stronger, thereby being able to remove the attachments more thoroughly.

[0012] Regarding the setting of the cutting part, the cutting part includes two cutting knives which are parallel and spaced apart. The two cutting knives are configured to be able to cut off the cartilage of the clavicles on the two supporting parts and the tracheal fascia attachments between the two clavicle bodies by rotation, and a material stripping piece is provided between the two cutting knives. The material stripping piece is configured to be able to strip off the cut cartilage and the tracheal fascia attachments between the two clavicle bodies by rotation.

[0013] As for the setting of the pressing part, the pressing part includes two guide rods with a gap relatively set, and the gap between the two guide rods is adapted to the cartilage protrusion. When in use, the two guide rods are respectively pressed down on both sides of the cartilage protrusion on the back of the clavicle, so that the pushing part pushes the clavicle to move along the bearing member toward the supporting plate. On the one hand, pressing down the clavicle facilitates the trimming work of the trimming unit, and on the other hand, provides a guide for the transportation of the clavicle, and the gap and height of the two guide rods are adjustable to adapt to clavicles of different specifications.

[0014] In order to improve the adaptability of the equipment, the guide rod is provided with two sections corresponding to the linear load-bearing section and the supporting section, and the heights of the two sections of the guide rod are adjustable respectively, so that the two guide rods can be flexibly adjusted according to different situations during cutting and oiling to enhance the adaptability of the equipment.

[0015] In order to reduce the space occupied by the equipment, the loading part is configured as a horizontally arranged three-section U-shaped structure, which also includes a straight material-smoothing section arranged parallel to one side of the straight load-bearing section, and an arc-shaped reversing section connecting the straight load-bearing section and the straight material-smoothing section, wherein the straight material-smoothing section includes two gaps and oppositely arranged material-smoothing parts, which are used for loading and smoothing the clavicle during batch processing, and the arc-shaped reversing section includes two gaps and oppositely arranged reversing parts, which are used for reversing when smoothing the clavicle. Compared with setting the loading part as a longer straight section, the structure is more compact and the space utilization rate is improved.

[0016] As for the setting of the pushing part, the pushing part includes a chain / belt transmission mechanism horizontally arranged on the inner side of the loading part, and a plurality of push rods capable of pushing the clavicle to move are arranged at intervals on the chain / belt transmission mechanism. As a better implementation method, a chain transmission mechanism is selected. Due to its precise chain link matching, it can provide stable thrust, ensuring the smooth movement of the clavicle during the trimming process, and reducing the displacement or damage of the clavicle caused by uneven thrust.

[0017] In order to further improve the stability of the pushing part, a sliding part is also provided on the other side of the loading part relative to the pushing part. The sliding part includes a guide block arranged along the conveying path, on which a guide groove is opened corresponding to the push rod, and the outer end of the push rod slides in sliding cooperation with the guide groove.

[0054] In order to further improve the stability of the pushing part 4, a sliding part is also provided on the other side of the loading part 2 relative to the pushing part 4. The sliding part includes a guide block 43 arranged along the conveying path, on which a guide groove is opened corresponding to the push rod 42, and the outer end of the push rod 42 slides in cooperation with the guide groove.

[0055] Combination Figure 2 and Figure 3The pressing part 3 includes a steering pressure plate 33 arranged on the upper side of the arc-shaped reversing section, and two guide rods 32 arranged on the upper side of the cutting unit, wherein the two ends of the steering pressure plate 33 are turned upward and outward, so that the clavicle 9 can smoothly enter and exit between the steering pressure plate 33 and the two reversing members 22, and the two guide rods 32 are arranged with a gap relative to each other, and are arranged on the upper frame through a mounting plate 31, and the gap between the two guide rods 32 is adapted to the cartilage protrusion 93, and the head ends of the two guide rods 32 are arc-shaped structures with openings facing the outer sides of the ends of the two reversing members 22. During cutting, the two guide rods 32 are respectively pressed down on both sides of the cartilage protrusion 93 on the back of the clavicle 9, so that the pushing part 4 pushes the clavicle 9 to move along the bearing member 23 toward the supporting plate. On the one hand, pressing down the clavicle 9 is convenient for the trimming unit to perform trimming work, and on the other hand, it provides guidance for the transportation of the clavicle 9, and the gap and height of the two guide rods 32 are adjustable to adapt to clavicle 9 of different specifications.

[0056] In order to improve the adaptability of the equipment, the guide rod 32 is provided with two sections corresponding to the linear load-bearing section and the supporting section, and the heights of the two sections of the guide rod 32 are adjustable respectively, so that the two guide rods 32 can be flexibly adjusted according to different situations during cutting and oiling, thereby enhancing the adaptability of the equipment.

[0057] Combination Figure 5 and Figure 7 The cutting part 5 includes a cutting assembly driven to rotate by a servo motor arranged on one side of the two supporting members 23, the cutting assembly includes a cutting seat of a columnar structure transmission connected to the servo motor, and cutting knives 51 arranged at both ends of the cutting seat, the two cutting knives 51 are arranged in parallel, and a material shifting piece 52 is also provided on the cutting seat between the two cutting knives 51, and the upper sides of the two cutting knives 51 protrude from the supporting member 23. When the clavicle 9 passes through the cutting assembly, the two cutting knives 51 can cut off the cartilage 91 of the clavicle 9 on the two supporting members 23 and the tracheal fascia attachment between the two clavicle main bodies 92 by rotating, and the cut cartilage 91 and the tracheal fascia attachment between the two clavicle main bodies 92 are shifted off by the material shifting piece 52.

[0058] Combination Figure 7 , two material-pickup members 52 are arranged on the outer circle of the cutting seat at an interval of 180 degrees. The material-pickup members 52 include mounting and material-pickup plates arranged at angles to each other. The middle part of the mounting plate 31 is connected to the cutting seat. The line connecting the outer end of the material-pickup plate to the rotation center is located on the side of the line connecting the outer end of the mounting plate 31 to the rotation center away from the rotation direction, and the distance from the outer end of the material-pickup plate to the root of the blade of the cutting knife 51 does not exceed 3 mm. When the material-pickup plate switches to cut off the accessory, the accessory can slide off from the outside of the material-pickup plate and the mounting plate 31, and the setting of the connection between the middle part of the mounting plate 31 and the cutting seat makes the accessory slide from the outside of the mounting plate 31 to the lower side of the cutting seat without passing through the cutting seat, thereby preventing the accessory from being entangled on the cutting seat, so as to facilitate the cleaning of the accessory.

[0059] Combination Figure 5 and Figure 6The supporting plate includes a first supporting plate 24 and a second supporting plate 25 which are sequentially arranged along the conveying direction of the clavicle 9. The oiling portion 6 includes two side oiling portions 6 and a middle oiling portion 6 which are respectively arranged in the mounting openings of the first supporting plate 24 and the second supporting plate 25. The two side oiling portions 6 include a partition rod 61 and first rotating screw groups 62 on both sides thereof. The two clavicle bodies 92 can respectively enter the two first rotating screw groups 62 to complete the oiling under the guidance of the partition rod 61. The middle oiling portion 6 is configured to complete the fine wiping of the remaining accessories or partial grease accessories between the cartilage 91 and the two clavicle bodies 92.

[0060] Furthermore, the middle greasing portion 6 includes a second rotating screw group 63 arranged along the conveying path. The clavicle 9 passes through the second rotating screw group 63, and the grease attachment between the upper cartilage 91 and the clavicle body 92 is greased off.

[0061] The oiling portion 6 performs targeted treatment on different areas of the clavicle 9 through the two side oiling portions 6 and the middle oiling portion 6, respectively, to avoid interference between accessories in different parts. The rotation speeds and other parameters of the first rotating screw group 62 and the second rotating screw group 63 can be adjusted separately, thereby achieving more accurate cleaning and effectively improving product quality.

[0062] Among them, the structure and working principle of the first rotating screw group 62 and the second rotating screw group 63 can be the same as the spiral screw group shown in patent application number CN202221645560.9, which will not be repeated here.

[0063] In order to more thoroughly wipe off the attachments between the cartilage 91 and the clavicle body 92, the second support plate 25 includes an inclined section 251 and a horizontal section 252 which are arranged in sequence. The first support plate 24 is arranged horizontally, and the upper side of the horizontal section 252 of the second support plate 25 is flush with the upper side of the first support plate 24. The inclined section 251 of the second support plate 25 is inclined upward to point in the conveying direction, and is arranged at an angle staggered with the second rotating screw group 63. This arrangement makes the head end of the second support plate 25 lower than the end of the first support plate 24, and the head end of the second rotating screw group 63 is higher than the upper side of the second support plate 25, so that the area between the cartilage 91 of the clavicle 9 and the clavicle bodies 92 on both sides is closer to the head end of the second rotating screw group 63. This makes the attachments in this area more accurately and forcefully wiped off when passing through the second rotating screw group 63. Because the distance is closer, the friction force, extrusion force and other effects of the second rotating screw group 63 on this part of the attachment are stronger, so that the attachments can be removed more thoroughly.

[0064] Combination Figure 6The supporting section also includes a transition plate 26 located between the bearing member 23 and the first supporting plate 24. The transition plate 26 is arranged to be inclined upward along the conveying direction, and a notch is provided in the middle of the front side of the transition plate 26. The end of the bearing member 23 is located in the notch. When the clavicle 9 passes through, under the action of the transition plate 26, the two clavicle main bodies 92 gradually tend to a horizontal state from a suspended state on the bearing member 23, thereby facilitating the two clavicle main bodies 92 to smoothly enter the first rotating screw for oiling.

[0065] This embodiment also provides a method for trimming the clavicle of a bird using the automatic trimming device described above, combined with Figure 1 and Figure 2 Generally speaking, the pruning method includes the following steps:
