Description

Technical Field

[0001] This invention belongs to the field of aquatic product processing machinery technology, and more specifically, relates to an automatic clam shell opening and meat extraction machine. Background Technology

[0002] With the rapid development of mechanization and intelligent technology in aquatic product processing, the level of automation in the primary processing of aquatic products is increasing, and more and more specialized processing equipment is being introduced into aquatic production. Aquatic product processing machinery is diverse in type and function, covering multiple stages such as cleaning, sorting, shell opening, meat extraction, and packaging. The widespread application of this equipment in production has not only significantly improved processing efficiency and product quality but also promoted the standardization, scaling up, and sustainable development of the aquatic product processing industry. Among these, the market demand for specialized equipment for shellfish shell opening and meat extraction is particularly urgent. This project focuses on the research and development of automated shellfish shell opening and meat extraction equipment for hard clams.

[0003] Clams, an important economic shellfish in my country, are prized for their delicious and nutritious meat, leading to a continuously growing market demand. However, the clam shell-opening and meat-extraction process has long faced numerous industry challenges: traditional processing methods rely heavily on manual labor, which is time-consuming, labor-intensive, and inefficient, and human contact can easily compromise food safety and product quality; existing processing equipment is mostly general-purpose, lacking dedicated integrated shell-opening and meat-extraction equipment for clams, resulting in poor coordination between processes and hindering continuous production; some batch processing equipment uses a violent shell-crushing method, which easily damages the clam meat and contaminates it with shell fragments, seriously affecting food safety and taste. Therefore, the industry urgently needs an automated, integrated, and precise clam shell-opening and meat-extraction device to replace manual operation and solve the efficiency, quality, and safety problems of traditional processing.

[0004] The hard clam possesses unique biological characteristics: its dorsal margin is slightly triangular, its ventral margin is rounded, its two shells are equal in size but unequal in size on both sides, its shell length is slightly greater than its shell height, its shell is thick and sturdy, and it has the property of opening naturally when heated. These characteristics provide a natural basis for automated processing. Based on this, biomimetic positioning, friction alignment, and comb-tooth correction devices can be designed to achieve automatic repositioning and directional transport of the hard clam. Combined with cross-positioning devices and cam-groove meat extraction devices, precise shell opening and injury-free meat extraction can be achieved, significantly reducing the breakage rate of clam meat.

[0005] Currently, existing clam processing equipment still has significant shortcomings: simple equipment is mostly single-function shell-opening equipment, relying on manual labor to complete subsequent processes such as meat extraction and packaging, which is inefficient and poses a high hygiene risk; some improved equipment integrates some processes, but lacks integrated design, resulting in poor coordination and integration between links, and failing to achieve full-process automation; highly automated equipment is expensive, complex in structure, difficult to operate and maintain, and difficult to adapt to individual differences in clams, failing to achieve precise meat extraction and resulting in a high rate of clam meat loss. Summary of the Invention

[0006] To address the aforementioned deficiencies or improvement needs of existing technologies, this invention provides an automatic clam shell-opening and meat-extracting machine. The heating and conveying mechanism achieves gentle initial shell opening of clams through precise temperature control without damaging the clam meat, simultaneously completing shell opening and automated conveying, reducing manual intervention and providing a stable supply of raw materials for subsequent processes. A separate feeding mechanism receives clams, enabling batch storage, orderly single-clam feeding, and precise guidance, preventing stacking and jamming. Multi-channel parallel feeding improves efficiency and ensures stable subsequent supply. A biomimetic clam groove array mechanism precisely clamps and positions clams, adaptively opening to accommodate different sizes, and working in conjunction with a cross-positioning mechanism for alternating... The machine operates smoothly, ensuring posture correction and meat extraction, and automatically discharging empty shells. The cross-positioning mechanism drives the biomimetic clam groove array mechanism for precise positioning, enabling parallel feeding and shell opening for meat extraction, improving overall machine efficiency, and ensuring stable operation throughout the entire process. The posture correction mechanism and the friction belt positioning mechanism work together to form a correction closed loop, accurately correcting the clam posture, adapting to different sizes, requiring no manual intervention, and ensuring meat extraction accuracy. The meat extraction mechanism achieves non-destructive meat extraction, accurately completing the entire meat extraction process, improving the integrity of clam meat, reducing the mixing of broken shells, and is fully automated, suitable for large-scale processing, ensuring product quality and food safety.

[0029] In this patent, the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0030] Example 1 like Figure 1-15As shown, this embodiment of the invention provides an automatic clam shell-opening and meat-extracting machine, including a heating and conveying mechanism 1, a separate feeding mechanism 2, a biomimetic clam groove array mechanism 3, a cross-positioning mechanism 4, a posture correction mechanism 5, a friction belt alignment mechanism 6, and a meat-extracting mechanism 7. The separate feeding mechanism 2 is provided in the middle of the side of the heating and conveying mechanism 1, and the cross-positioning mechanism 4 is provided in the lower side of the heating and conveying mechanism 1, with the lower end of the separate feeding mechanism 2 facing the top of the cross-positioning mechanism 4. The biomimetic clam groove array mechanism 3 is fixedly mounted on the top of the cross-positioning mechanism 4. The posture correction mechanism 5 is provided between the biomimetic clam groove array mechanism 3 and the separate feeding mechanism 2. The friction belt alignment mechanism 6 is provided at the bottom of the biomimetic clam groove array mechanism 3. The meat-extracting mechanism 7 is fixedly mounted on the top of the end of the cross-positioning mechanism 4 away from the biomimetic clam groove array mechanism 3. This invention solves the technical pain points of traditional clam processing, such as high manual intervention, low meat extraction efficiency, easy meat damage, and poor process connection, through the integrated design and orderly linkage of various mechanisms. The heating and conveying mechanism 1 provides stable preconditions for subsequent shell opening and meat extraction. The separate feeding mechanism 2 realizes orderly feeding of single clams, effectively avoiding stacking and material jamming risks, and ensuring the stability of material supply. The friction belt alignment mechanism 6 and posture correction mechanism 5 can accurately correct the clam posture, ensuring the accuracy of subsequent meat extraction. Posture alignment can be completed without manual intervention, reducing the intensity of manual labor. The cross-positioning mechanism 4 realizes efficient switching of workstations, allowing the feeding alignment and shell opening and meat extraction processes to be carried out in parallel, greatly improving the continuity of processing and production efficiency. The meat extraction mechanism 7 can realize non-destructive meat extraction of clams, maximizing the preservation of the integrity and freshness of the clam meat, and improving product quality and meat extraction rate. The equipment is highly automated, realizing the entire process of clam opening, feeding, posture correction, repositioning, and meat extraction in one integrated manner, replacing the traditional manual processing mode. It not only reduces labor costs but also avoids hygiene hazards caused by manual operation, improves the standardization of processing, and is suitable for large-scale clam primary processing scenarios, with good economic benefits and application prospects.

[0031] Furthermore, the heating and conveying mechanism 1 includes a support 11, a heating rod 12, a heating groove 13, a hollow clam chamber 14, and a conveying assembly 15. The heating groove 13 is fixedly mounted between two vertical rods of the support 11, and the heating rod 12 is embedded inside the heating groove 13. The hollow clam chamber 14 is housed within the heating groove 13, and several through holes are provided on its circumferential sidewalls and bottom. The conveying assembly 15 is fixedly mounted on the connecting rod in the middle of the support 11, and the conveying assembly 15 is fixedly connected to the hollow clam chamber 14. It is used to move the hollow clam chamber 14 to the top of the separate feeding mechanism 2, so that the clams inside are transferred to the storage trough 21 in the separate feeding mechanism 2. Through the coordinated cooperation of various components, the batch precise temperature-controlled heating and opening of the clams can be achieved. It can also smoothly transport clams, providing a stable and reliable pre-process guarantee for subsequent single-clam feeding, posture correction, and non-destructive meat extraction. The embedded cooperation between the heating tank 13 and the heating rod 12 can achieve precise temperature control of the water in the tank. The temperature difference will cause the clams to open initially, and the opening width can be controlled, laying a good foundation for the subsequent meat extraction process. Several through holes on the circumferential side wall and bottom of the hollow clam chamber 14 can allow the hot water in the heating tank 13 to fully penetrate into the hollow clam chamber 14, achieving uniform heating of the clams and ensuring that all clams are in the same opening state. The fixed connection between the conveying component 15 and the hollow clam chamber 14 can drive the hollow clam chamber 14 to move smoothly in the heating tank 13, realizing the conveying of clams without the need for manual transfer of clams, reducing manual intervention and reducing labor intensity.

[0032] Further, the conveying assembly 15 includes a double-ear chain 151, sprockets 152, a first 42-stepper motor 153, a motor bracket 154, an aluminum tube 155, a first gear 156, a second gear 157, and a first bearing seat 158; the first bearing seat 158 ​​is fixedly mounted on each of the four connecting rods on both sides of the bracket 11; an aluminum tube 155 is rotatably mounted between the two first bearing seats 158 at the upper and lower parts of the bracket 11; two sprockets 152 are symmetrically mounted on the outer side of each aluminum tube 155; a double-ear chain 151 is mounted on the outer side of the two corresponding sprockets 152; the two double-ear chains 151 are fixedly connected to the outer wall of the hollow clam shell compartment 14; the lower aluminum tube 155... A first gear 156 is fixedly mounted on the outer side of the end near the first bearing seat 158. The first 42 stepper motor 153 is fixedly mounted on the vertical rod of the bracket 11 through the motor bracket 154. A second gear 157 is fixedly mounted on the output end of the first 42 stepper motor 153. The second gear 157 meshes with the first gear 156 for transmission. The first 42 stepper motor 153 drives the hollow clam bin 14 to move smoothly to the top of the grooved wheel separate feeding mechanism 2, so that the clams inside the hollow clam bin 14 are accurately transferred to the storage trough 21 of the grooved wheel separate feeding mechanism 2, realizing the automated conveying of clams. This conveying method does not require manual transfer of clams, effectively reducing manual intervention and reducing the intensity of manual labor.

[0033] Specifically, after the first stepper motor 153 starts, its output end drives the second gear 157 fixed on it to rotate synchronously. Through the meshing transmission between the second gear 157 and the first gear 156, the power is transmitted to the lower aluminum tube 155. The aluminum tube 155 rotates smoothly under the support of the first bearing seats 158 on both sides, which in turn drives the sprocket 152 mounted on its outer side to rotate synchronously. The sprocket 152 drives the double-ear chain 151 meshing with it to make uniform linear motion. Since the double-ear chain 151 is fixedly connected to the outer wall of the hollow clam bin 14, the double-ear chain 151 drives the hollow clam bin 14 to move smoothly to the top of the grooved wheel separate feeding mechanism 2, so that the clams inside the hollow clam bin 14 are accurately transferred to the storage trough 21 of the grooved wheel separate feeding mechanism 2, realizing the automated conveying of clams. This conveying method does not require manual transfer of clams, effectively reducing manual intervention and reducing the intensity of manual labor.

[0034] Furthermore, the separate feeding mechanism 2 is fixedly assembled to the front end of the support 11, and includes a storage trough 21, a feeding assembly 22, and a guide groove 23. The storage trough 21 is fixedly assembled to the front end of the support 11, and three parallel channels are formed in the bottom of the storage trough 21 for initial positioning and diversion of the clams. The feeding assembly 22 is fixedly assembled to the lower end of the storage trough 21, and the guide groove 23 is fixedly assembled to the lower end of the feeding assembly 22. The guide groove 23 has three channels that correspond to the channels in the storage trough 21. A corresponding and coaxially arranged channel is used for the precise guiding and conveying of clams. Through the coordinated operation of the storage tank 21, the feeding component 22, and the guide channel 23, the orderly storage, single-piece feeding, and precise guidance of clams are achieved, providing a stable supply guarantee for the subsequent posture correction process. The storage tank 21 is fixedly assembled at the front end of the bracket 11, which can realize the batch temporary storage of clams, receiving clams from the hollow clam bin 14 and preventing clams from piling up and scattering. The three parallel channels opened inside can perform preliminary diversion and limiting of the temporarily stored clams, so that the clams are orderly. The arrangement of the clams lays the foundation for subsequent single-clam feeding, while preventing the clams from being squeezed and collided with each other during storage, thus ensuring the processing quality of the clams. The storage tank 21, the feeding component 22, and the guide channel 23 are fixedly assembled from top to bottom, with a reasonable layout and tight connection, realizing the integrated connection of clams from temporary storage, feeding to guidance, without the need for manual assistance in transportation, reducing manual intervention and labor intensity; the three channels in the guide channel 23 correspond one-to-one with the channels in the storage tank 21 and are set coaxially, ensuring that the clams are fed through the channel. After component 22 is unloaded, it is precisely conveyed to the biomimetic clam array mechanism 3 along the channel of guide groove 23, avoiding clam offset and falling, improving unloading accuracy and conveying stability. The design of 3 channels can realize multi-channel parallel unloading of clams, improving unloading efficiency while ensuring the unloading accuracy of a single clam, and adapting to the needs of large-scale clam processing. Each channel is independent of each other, which can effectively avoid mutual interference and stacking jamming of clams during the conveying process, further improving the smoothness and stability of unloading, and ensuring the orderly progress of subsequent posture correction and meat removal processes.

[0035] Further, the feeding assembly 22 includes a roller shell 221, a roller 222, a second 42 stepper motor 223, a motor base 224, a fixing frame 225, and a sealing plate 226. The roller shell 221 has through slots at its top and bottom, which correspond one-to-one with the channels in the storage groove 21 and the guide groove 23 and are coaxially arranged. The roller 222 is rotatably mounted inside the roller shell 221. The roller 222 has symmetrically arranged channels along its circumference, and the channels on the roller 222 are adapted to the through slots at the top and bottom of the roller shell 221. One end of the roller 222 is fixedly connected to the output end of the second 42 stepper motor 223. The second 42 stepper motor 223 is fixedly mounted on the vertical rod of the bracket 11 via the motor base 224. A sealing plate 226 is fixedly mounted on the inner wall of the motor base 224. The sealing plate 226 is bolted to the inside of one end of the roller shell 221 for controlling one end of the roller 222. For sealing and limiting, the other end of the roller shell 221 is fixedly mounted on the vertical rod of the bracket 11 through the fixing frame 225, realizing bidirectional fixed support of the roller shell 221. The through grooves at the top and bottom of the roller shell 221 correspond one-to-one with the channels of the storage trough 21 and the guide groove 23 and are coaxially set to ensure that the clams can accurately enter the roller shell 221 after falling from the storage trough 21. After being fed by the roller 222, they are smoothly conveyed along the guide groove 23, avoiding the clams from shifting or getting stuck during the transfer process, and improving the feeding connection accuracy. The circumferentially symmetrically opened channels of the roller 222 are adapted to the through grooves of the roller shell 221, which can realize the precise holding and limiting of the clams, ensuring that only one clam is fed at a time, ensuring the accuracy of single-clam feeding. By adjusting the rotation speed and rotation angle of the roller 222, the feeding speed can be precisely controlled to adapt to the feeding requirements of clams of different sizes. At the same time, it ensures that the feeding action is precisely synchronized with the subsequent posture correction and meat removal process, improving the overall coordination of the equipment.

[0036] Specifically, the second stepper motor 223 is started, and its output drives the roller 222 to rotate smoothly inside the roller shell 221. The sealing plate 226 seals and limits the roller 222 to prevent rotational deviation. The circumferential channel of the roller 222 rotates with it. When the channel is aligned with the upper and lower through slots of the roller shell 221, the clams in the storage tank 21 fall into the groove of the roller 222 through the channel. As the roller rotates, they fall to the bottom through slot, realizing single-piece feeding. The feeding speed can be precisely controlled by adjusting the roller speed. After feeding, the clams fall into the guide groove 23 through the bottom through slot of the roller shell 221 and are accurately conveyed along the channel to the bionic clam groove 352 in the bionic clam groove array mechanism 3 to supply material for subsequent processes.

[0037] Furthermore, two biomimetic clam groove array mechanisms 3 are provided, and the two biomimetic clam groove array mechanisms 3 are respectively fixedly assembled on the top of the first transposition plate 45 and the second transposition plate 46. Each mechanism includes a drive assembly 31, a cam disk 32, a cam groove 33, a cam follower 34, a clamping assembly 35, a first guide assembly 36, and a second guide assembly 37. The drive assembly 31 is fixedly assembled on the top of the first transposition plate 45 or the second transposition plate 46, and the output end of the drive assembly 31 is fixedly assembled with a cam disk 32. The cam disk 32 has a portion that matches the first cam follower 34. The cam groove 33 is obliquely arranged, and the first cam follower 34 is fixedly assembled on the top of the clamping assembly 35 and is snapped into the cam groove 33 to realize the transmission connection between the cam disk 32 and the clamping assembly 35. The bottom of both ends of the cam disk 32 are provided with a first guide assembly 36 between the bottom of the first shift plate 45 or the second shift plate 46 for guiding and limiting the movement of the cam disk 32. The bottom of the clamping assembly 35 is provided with a second guide assembly 37 between the bottom of the clamping assembly 35 and the first shift plate 45 or the second shift plate 46 for guiding and limiting the movement of the clamping assembly 35. Two biomimetic clam groove array mechanisms 3 are respectively mounted on the top of the first transposition plate 45 and the second transposition plate 46. They can work in conjunction with a cross-transposition mechanism to achieve alternating operation. One mechanism supports the clam for posture correction, while the other mechanism works in sync with the meat extraction process, significantly improving the equipment's processing efficiency. The drive component 31 drives the cam disk 32 to move back and forth. Through the sliding engagement of the cam groove 33 and the first cam follower 34, the back and forth movement of the cam disk 32 is converted into the lateral opening and closing movement of the clamping component 35, achieving precise control of the opening and closing range of the clamping component 35 to adapt to the clamping requirements of clams of different sizes. The first guide component 36 guides the convex... The wheel 32 provides guidance and limit, and the second guide component 37 provides guidance and limit for the clamping component 35, effectively preventing deviation and jamming during their movement, ensuring stable and reliable operation of the mechanism, and improving clamping and positioning accuracy. The clamping component 35 can accurately clamp and position the clam, providing stable support for the posture correction operation of the friction belt alignment mechanism and the comb-type posture correction mechanism, ensuring that the clam posture correction is accurate and in place, laying a good foundation for the subsequent non-destructive meat removal process; at the same time, the flexible opening and closing of the clamping component 35 can quickly release the empty shell after the meat is removed, realizing the automatic detachment and discharge of the empty shell, improving the smoothness of process connection.

[0038] Furthermore, the drive assembly 31 includes a 35 stepper motor 311, a first coupling 312, a first lead screw 313, a lead screw nut 314, and a nut fixing block 315. The 35 stepper motor 311 is fixedly mounted on the top of the first shift plate 45 or the second shift plate 46. The output end of the 35 stepper motor 311 is fixedly mounted with the first coupling 312. The end of the first coupling 312 away from the 35 stepper motor 311 is connected to the first lead screw 313. The lead screw nut 314 is threadedly connected to the outer side of the first lead screw 313. The nut fixing block 315 is fixedly mounted on the outer side of the lead screw nut 314. The side wall of the nut fixing block 315 is fixedly connected to the end of the cam disk 32, thereby realizing the power transmission between the drive assembly 31 and the cam disk 32.

[0039] Furthermore, the clamping assembly 35 includes a clam groove fixing plate 351 and a biomimetic clam groove 352; the bottom of the cam disk 32 is provided with multiple clam groove fixing plates 351, and a first cam follower 34 is fixedly mounted on the top of one end of each clam groove fixing plate 351. Three biomimetic clam grooves 352 are fixedly mounted on the opposite sidewalls of every two opposing clam groove fixing plates 351 along their length direction. The biomimetic clam grooves 352 conform to the shape of the clam and are used to firmly clamp and accurately position the clam. The close fit of the biomimetic clam grooves to the clam shape achieves firm clamping of the clam while avoiding damage to the clam meat, ensuring processing quality. The arrangement of three biomimetic clam grooves on each pair of fixing plates can realize batch clamping of clams and improve processing efficiency. The overall structure is simple and the linkage with the first cam follower is smooth, providing stable positioning support for subsequent posture correction and meat removal processes, ensuring the overall operating accuracy of the equipment.

[0040] Furthermore, the first guide assembly 36 includes a first slider 361 and a first slide rail 362. The first slider 361 is fixedly mounted on the bottom of both ends of the cam disk 32, and the first slide rail 362 is fixedly mounted on the top of the first shift plate 45 or the second shift plate 46. The first slider 361 and the first slide rail 362 slide in cooperation, and can move smoothly along the slide rail, effectively limiting the movement trajectory of the cam disk 32 and the clamping assembly, and avoiding problems such as offset and jamming.

[0041] Furthermore, the second guide component 37 includes a second slider 371 and a second slide rail 372. The second slider 371 is fixedly mounted on the bottom of the clam groove fixing plate 351, and the second slide rail 372 is fixedly mounted on the top of the first shift plate 45 or the second shift plate 46. The second slider 371 and the second slide rail 372 are slidably engaged, allowing the slider to slide smoothly along the second slide rail 372. The bottom of the clam groove fixing plate 351 is fixedly connected to the second slider 371, driving the clam groove fixing plate 351 and the bionic clam groove above it to move synchronously. Through the sliding engagement of the second slider and the second slide rail, the clam groove fixing plate can move smoothly, ensuring smooth actions such as posture correction and clam meat handling, and avoiding jamming or deviation.

[0042] Specifically, the 35 stepper motor 311 is started, which drives the first lead screw 313 to rotate via the first coupling 312. The lead screw nut 314 and the nut fixing block 315 convert the rotational motion into linear motion, driving the cam disk 32 to move back and forth. When the cam disk 32 moves, the oblique cam groove 33 slides and engages with the first cam follower 34, converting the forward and backward displacement of the cam disk into the lateral opening and closing motion of the clamping assembly 35, which drives the pair of clam groove fixing plates 351 to open and close relative to each other, so that the bionic clam groove 352 clamps or releases the clam. During the movement, the first slider 361 slides along the first slide rail 362 to guide and limit the cam disk 32, and the second slider 371 slides along the second slide rail 372 to ensure that the clam groove fixing plate 351 moves smoothly and prevents deviation and jamming. The two sets of bionic clam groove array mechanisms operate alternately. One set clamps the clam for posture correction, and the other set works together to remove the meat and release the empty shell, realizing continuous operation.

[0043] Furthermore, the cross-positioning mechanism 4 includes a mounting frame 41, a guide plate 42, a second drive assembly 43, a synchronization assembly 44, a first position plate 45, a second position plate 46, and a moving assembly 47. The second drive assembly 43 is fixedly mounted on the top of one side of the mounting frame 41. The second drive assembly 43 is connected to the first position plate 45 and is used to drive the first position plate 45 to move. The synchronization assembly 44 is fixedly mounted inside the mounting frame 41 and is connected to both the first position plate 45 and the moving assembly 47 to achieve synchronous linkage between them. The top of the moving assembly 47 is fixedly mounted with... There is a second shift plate 46. The moving component 47 is slidably connected to the guide plate 42. The guide plate 42 is fixed inside the mounting frame 41. The guide plate 42 guides and limits the movement of the moving component 47. Through the coordinated cooperation of various components, the precise cross-positioning of the first shift plate and the second shift plate is achieved. The second drive component provides stable power and works with the synchronization component to achieve synchronous linkage of the first and second shift plates, ensuring precise synchronization of the shifting action, improving the efficiency of process connection. The sliding cooperation between the moving component and the guide plate ensures precise limiting and avoids deviation or jamming during the shifting process, ensuring the stability of the mechanism operation.

[0044] Furthermore, a limiting groove 421 is formed on the guide plate 42. The limiting groove 421 includes a first horizontal groove 4211, an inclined groove 4212, and a second horizontal groove 4213. The first horizontal groove 4211 is formed in the middle of the guide plate 42, the inclined grooves 4212 are symmetrically formed at both ends of the first horizontal groove 4211, and the second horizontal groove 4213 is formed at the end of the inclined groove 4212. The inner cavities of the first horizontal groove 4211, the inclined groove 4212, and the second horizontal groove 4213 are connected. The second cam follower 477 is formed in the first horizontal groove 4211. 1. The first shift plate 45 moves under the limiting of the inclined groove 4212 and the second horizontal groove 4213. The second horizontal groove 4213 facilitates the limiting of the first shift plate 45 to the same height as the second shift plate 46. The inclined groove 4212 guides the movement of the second shift plate 46 downward. With the guidance of the first horizontal groove 4211, when the first shift plate 45 moves in an alternating motion relative to the second shift plate 46, it moves downward and bypasses the translational movement of the first shift plate 45, thus enabling the first shift plate 45 and the second shift plate 46 to move in an alternating motion.

[0045] Furthermore, the second drive assembly 43 includes a 57-stepper motor 431, a second coupling 432, a threaded rod 433, and a nut seat 434. The 57-stepper motor 431 is fixedly mounted on one end of the mounting bracket 41. The output shaft end of the 57-stepper motor 431 is connected to the second coupling 432. The threaded rod 433 is fixedly mounted on the end of the second coupling 432 away from the 57-stepper motor 431. The other end of the threaded rod 433 away from the second coupling 432 is rotatably mounted to the other end of the mounting bracket 41. The nut seat 434 is threadedly connected to the threaded rod 433. The nut seat 434 is fixedly connected to the connecting block 451 on the first shift plate 45 to realize power transmission to drive the first shift plate 45 to move.

[0046] Further, the synchronization component 44 includes a first support frame 441, a synchronous pulley 442, a synchronous belt idler pulley 443, a first synchronous belt 444, a mounting plate 445, an adjusting plate 446, and a connecting seat 447. The first support frame 441 is fixedly assembled inside the mounting frame 41. Mounting plates 445 are fixedly mounted at both ends of the first support frame 441. Each mounting plate 445 has two synchronous pulleys 442 rotatably mounted on it via a rotating shaft. The two synchronous pulleys 442 are arranged vertically. The mounting plate 445 has an oblong hole. The adjusting plate 446 has symmetrically distributed adjusting holes. Bolts pass through the adjusting holes and are fixedly connected to the mounting plate 445, allowing flexible adjustment of the mounting position of the adjusting plate 446. The adjusting plate 446 has a synchronous belt idler pulley 443 rotatably mounted on it via a rotating shaft passing through the oblong hole. The first synchronous belt 444 is sleeved and assembled between the synchronous pulleys 442 and the synchronous belt idler pulley 443, forming a closed loop. The ring drive structure ensures the stability and continuity of power transmission. The connecting seats 447 are diagonally distributed and fixedly assembled on the first synchronous belt 444. One connecting seat 447 is fixedly connected to the bottom of the first shift plate 45, and the other connecting seat 447 is fixedly connected to the slide plate 475. Since the two connecting seats 447 are arranged diagonally, when the first synchronous belt 444 is running, it can drive the two connecting seats 447 to move alternately, thereby driving the first shift plate 45 and the second shift plate 46 to achieve alternate movement and complete the shifting action. Through the cooperation of the synchronous belt pulley, the synchronous belt and the synchronous belt idler pulley, the power is smoothly transmitted, reducing transmission loss and ensuring that the shifting action is precise and controllable. The design of the waist-shaped hole and the adjustment hole can flexibly adjust the installation position of the components and adjust the tension of the synchronous belt, improving the adaptability of the components. The diagonally arranged connecting seats realize the alternate movement of the first shift plate and the second shift plate, effectively improving the work efficiency.

[0047] Further, the movable component 47 includes a second support frame 471, a third slide rail 472, a third slider 473, a plug rod 474, a slide plate 475, a first connecting rod 476, a second cam follower 477, and a limiting connecting rod 478.

The plug rods 474 and the slide plate 475 are slidably interlocked, enabling relative sliding between them. Third sliders 473 are fixedly assembled at both ends of the bottom of the slide plate 475. The third sliders 473 slide in cooperation with the third slide rail 472, allowing the third slide plate 475 to slide along the third slide rail 472. Smooth movement effectively avoids movement jamming. This moving component enables smooth movement and precise positioning of the second shift plate, reducing offset and wear during movement. A first connecting rod 476 is fixedly installed at the bottom of the second shift plate 46. A second cam follower 477 is fixedly installed on the bottom side of the first connecting rod 476.

[0049] Furthermore, both the first shift plate 45 and the second shift plate 46 are provided with square through holes, the clamping assembly 35 is located above the square through holes, and the friction band alignment mechanism 6 is located below the square through holes.

[0050] Specifically, the 57 stepper motor 431 is started, which drives the threaded rod 433 to rotate via the second coupling 432. The nut seat 434 converts the rotational motion into linear motion, driving the first shifting plate 45 to move smoothly along the fourth slider 452 and the fourth slide rail 453. When the first shifting plate 45 moves, it drives the connecting seat 447 connected to it in the synchronization assembly 44 to move, thereby driving the first synchronous belt 444 to rotate in a closed loop around the synchronous belt pulley 442 and the synchronous belt idler pulley 443. Since the two connecting seats 447 are diagonally distributed, when the first synchronous belt 444 rotates, it drives the other connecting seat 447 to move synchronously and alternately, thereby driving the moving assembly 47. The slide plate 475 slides along the third slide rail 472, and the slide plate 475 drives the second shift plate 46 to move synchronously. The second cam follower 477 at the bottom of the second shift plate 46 moves along the limiting groove 421 of the guide plate 42, and moves downward under the guidance of the inclined groove 4212. Then it is guided by the first horizontal groove 4211 and forms an interlaced motion with the first shift plate 45, bypassing the translation trajectory of the first shift plate 45. During the entire driving process, the synchronization component ensures that the first and second shift plates move in precise synchronization. Each slide rail and slider cooperates to achieve guidance and limitation, avoiding deviation and jamming. Finally, the two are accurately cross-positioned, realizing alternating operation and improving the efficiency of process connection.

The third gear 525 meshes with the rack 521 to form a power transmission structure. The combing component 59 is detachably fixedly connected to the end of the 3D printed follower 527 for easy maintenance and replacement. Through the meshing transmission of the rack and gear, the combing component 59 achieves precise movement, ensuring the stability and accuracy of the posture correction action and effectively avoiding clam posture deviation. Secondly, the 3D printed follower 527, combined with the slide rail slider structure, reduces motion friction and improves the smoothness of the movement. Simultaneously, the detachable combing component reduces maintenance costs and provides precise posture assurance for the subsequent meat extraction process.

[0053] Specifically, the third stepper motor 526 is started to drive the third gear 525 to rotate. The third gear 525 meshes with the rack 521 fixed on one side of the second connecting rod 51, converting the rotational motion into linear motion. The 3D printed follower 527 slides smoothly along the fourth slide rail 523 on the outside of the connecting piece 522 and the rack 521 through the fourth slider 524 on the inner side of its lower end, thereby driving the comb 59 detachably connected to its end to move, accurately correcting the posture of the clam held in the biomimetic clam groove 352, ensuring that the clam's posture meets the requirements of subsequent processing steps, and completing the entire drive process.

[0054] Furthermore, the friction band alignment mechanism 6 includes a frame 61, a fourth drive assembly 62, an alignment assembly 63, a lead screw slide 64, and fixed rods 65.

Between shafts 633, a closed-loop transmission structure is formed. The top of the conveyor belt 634 is directly opposite the square through holes on the first shift plate 45 and the second shift plate 46. Under the drive of the active rotating shaft 632, it rotates synchronously. During operation, the conveyor belt 634 contacts the clam surface during rotation and realizes automatic flipping and posture correction of the clam through sliding friction. It can correct reversed or misaligned clams to the standard opening orientation without manual intervention. It can also be adapted to clams of different specifications through height adjustment and form a synergistic cooperation with the posture correction mechanism to achieve efficient posture correction of batch clams.

[0057] Specifically, the brushless motor 621 is started, and its output power is transmitted to the drive pulley 623. Through the second synchronous belt 625, the driven pulley 624 is driven to rotate synchronously. The driven pulley 624 further drives the drive shaft 632 of the alignment component 63 to rotate, and at the same time, the driven shaft 633 rotates synchronously, thereby driving the conveyor belt 634 to run smoothly.

The tweezers opening and closing plates 743 have Y-shaped grooves corresponding to the number of tweezers 741. The two branch grooves of the Y-shaped groove intersect to form a tip, which is inserted between the two clamping arms of the tweezers 741. The Y-shaped groove is used to adjust the distance between the two clamping arms of the tweezers 741. The main groove of the Y-shaped groove can further fine-tune the distance between the two clamping arms of the tweezers 741, so as to achieve precise control of the opening and closing range of the tweezers. By cooperating with the clamping arms of the tweezers 741 through the Y-shaped groove on the tweezers opening and closing plate 743, the opening and closing distance of the clamping arms of the tweezers 741 can be precisely adjusted. During operation, the clamping arms of the tweezers 741 are first adjusted to a small distance so that the tweezers 741 can be smoothly inserted into the inner cavity of the clam. Then, the distance between the clamping arms of the tweezers 741 is gradually adjusted through the Y-shaped groove to adapt to the size of the clam meat. Then, the distance between the clamping arms of the tweezers 741 is further adjusted through the Y-shaped groove so that the tweezers 741 can firmly hold the clam meat and lift it upward to complete the meat removal action. The sixth slider 744 and the sixth slide rail 745 form a sliding engagement, which can ensure that the tweezers opening and closing plate 743 moves in one direction along the preset trajectory, avoiding jamming or deviation during operation, and effectively ensuring the stability and reliability of the tweezers 741 in holding the clam meat during the meat removal process.

[0062] Furthermore, the drive assembly 75 includes a fourth 42-stepper motor 751, a motor connecting plate 752, a third coupling 753, a second lead screw 754, and a threaded seat 755.

[0063] Furthermore, the lower part of the meat extraction mechanism 7 is equipped with a clam meat collection box for collecting clam meat.

[0064] Specifically, the fourth stepper motor 751 is started, and its output drives the third coupling 753 to rotate, which in turn drives the second lead screw 754 to rotate synchronously. The second lead screw 754 is threadedly engaged with the threaded seat 755, converting the rotational motion into linear motion, which drives the threaded seat 755 and the tweezers opening and closing plate 743 fixedly connected to it to move smoothly. When the tweezers opening and closing plate 743 moves, the Y-shaped groove cooperates with the tweezers clamping arm to realize the opening and closing action of the tweezers 741. First, the clamping arm of the tweezers 741 is adjusted to a small gap state so that the tweezers 741 can be smoothly inserted. The clam's inner cavity is then accessed, and the spacing of the gripping arms of the tweezers 741 is gradually adjusted via the Y-shaped groove to fit the size and specifications of the clam meat. The spacing of the gripping arms of the tweezers 741 is then further adjusted via the Y-shaped groove to ensure that the tweezers 741 firmly grip the clam meat. Subsequently, the lifting component drives the meat removal action. Then, the driving component 75 drives the tweezers opening and closing plate 743 to increase the spacing of the gripping arms of the tweezers 741, releasing the clam meat and allowing it to automatically fall into the lowered clam meat collection box. The entire process is automated without human intervention, achieving automated meat removal and meeting the needs of large-scale processing.

[0065] Furthermore, the cross-positioning mechanism 4 is equipped with a clam shell collection box for collecting clam shells after the meat has been removed. When the cross-positioning mechanism 4 moves the bionic clam groove array mechanism 3 to directly above the clam shell collection box, the clamping component 35 of the bionic clam groove array mechanism 3 automatically opens and closes to release the empty shells. The empty shells fall from the bionic clam groove 352 and fall through the square through holes on the first position plate 45 or the second position plate 46, accurately falling into the clam shell collection box, realizing the automatic collection of clam shells without manual cleaning, and further improving the continuity of the process.
