Description

Technical Field

[0001] This invention relates to the field of aquatic product processing technology, specifically to a mussel ultra-low temperature shelling processing device. Background Technology

[0002] Mussels are widely popular due to their rich nutritional value and delicious taste. Shelling is a crucial step in mussel processing. Current technologies primarily employ mechanized methods or manual operation for this process. Manual shelling relies on operators peeling the mussels, offering flexibility and precision suitable for small-scale production. Mechanized shelling equipment, on the other hand, improves processing efficiency through methods such as squeezing, impact, or cutting, and, combined with conveyor belts and separating mechanisms, achieves a degree of automation. These technologies have yielded good results in practice, providing a foundation for large-scale processing. However, due to the unique structure of mussels and the tight connection between their flesh and shell, existing technologies still have room for further optimization in certain aspects.

[0003] For example, while mechanical extrusion and impact shelling methods improve efficiency, they are difficult to fully protect the mussel meat, potentially causing damage to some mussels during operation. Furthermore, during mussel transport, the lack of a well-designed conveyor belt for even distribution can lead to mussel accumulation in certain areas, resulting in uneven processing and affecting shelling efficiency. Additionally, the need for flexible equipment adjustments for separating and quantifying mussels of different sizes presents challenges, and existing technologies have limitations in quickly adapting to different sizes. Overall, current technologies provide a reliable foundation for mussel shelling, but there is still potential for improvement in areas such as meat quality protection, even distribution, and quantitative flexibility.

[0023] This invention provides a cryogenic shelling process for mussels. It has the following beneficial effects:

[0024] 1. This invention uses a refrigeration mechanism to rapidly freeze mussels, utilizing the principle of thermal expansion and contraction to naturally separate the mussel shell from the meat. Compared to traditional mechanical shelling methods, this avoids damage to the mussel meat caused by high-intensity compression or friction. It not only effectively maintains the integrity and tenderness of the mussel meat but also significantly improves the efficiency and quality of mussel shelling. In addition, rapid freezing can effectively inhibit the growth of microorganisms, extend the shelf life of mussels, and provide assurance for subsequent processing or transportation.

[0025] 2. The present invention uses a distribution mechanism to ensure that mussels are evenly distributed on the conveyor belt before entering the shelling and cooling mechanisms, preventing mussels from piling up or overlapping. This design ensures that each mussel can fully contact the processing device, which helps to facilitate the smooth shelling process and avoids uneven processing caused by piling up. At the same time, the separated mussels can enter the subsequent processing stages at a stable pace, improving the processing efficiency of the equipment and reducing manual intervention.

[0026] 3. This invention uses a quantitative mechanism to precisely separate mussels, ensuring consistent processing volume for each batch and improving the standardization of processing. For mussels of different sizes, the drive shaft and rotating column can be quickly separated by adjusting the turntable, facilitating the replacement of separation components adapted to different mussel sizes. This enhances the adaptability of the equipment, greatly simplifies the maintenance and adjustment process, reduces downtime, and provides convenience for practical production applications.

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see the appendix Figure 1 - Appendix Figure 4 This invention provides a mussel cryogenic shelling treatment device, comprising:

[0037] Frame 1, which serves as the overall frame of the equipment, is used to facilitate the formation of the sealed space required for freezing;

[0038] The metering mechanism 2, which is located on top of the frame 1, is used to meterly deliver the poured mussels out.

[0039] The shelling mechanism 3 is located on one side of the frame 1 and is used to quickly shell the frozen mussels.

[0040] The refrigeration unit 4, which is located inside the frame 1, is used to quickly freeze the mussels;

[0041] The equalization mechanism 5 is located at the bottom of the quantitative mechanism 2 and is used to evenly distribute the delivered mussels.

[0042] The conveyor belt 6, which is located at the bottom of the equalization mechanism 5, is used to transport the mussels after quantitative delivery;

[0043] The receiving box 8 is located on one side of the shelling mechanism 3 and is used to collect the shelled mussels together with their shells for subsequent sorting.

[0044] The quantitative mechanism 2 includes a feeding hopper 21, a dispensing tank 22 fixed at the bottom of the feeding hopper 21, a dispensing pipe 23 fixed at the bottom of the dispensing tank 22, a motor 27 on one side of the dispensing tank 22, a drive shaft 28 fixed at the output end of the motor 27, a rotating column 24 sliding on the outer wall of the drive shaft 28, partition plates 25 arranged in a ring array fixed on the outer wall of the rotating column 24, and a turntable 26 rotatably connected to one side of the rotating column 24, the turntable 26 being threadedly connected inside the dispensing tank 22.

[0045] Specifically, when mussels need to be shelled, all mussels should first be poured into the equipment from the feed hopper 21. The mussels will then smoothly enter the internal space of the portioning tank 22. At this point, motor 27 starts operating normally, driving the rotating column 24 to rotate via drive shaft 28. As the rotating column 24 rotates, the partition plate 25 mounted on it rotates around the rotating column 24, thus dividing the incoming mussels into relatively uniform units according to a certain quantity. This separation process is both fast and efficient, avoiding mussel accumulation or uneven distribution.

[0046] It is worth noting that when processing mussels of different sizes, to better accommodate the overall size distribution of the mussels, the turntable 26 can be adjusted to separate the rotating column 24 from the drive shaft 28. Subsequently, the rotating column 24 and the separator plate 25 can be replaced to accommodate the new separation space size, thus achieving quantitative separation of mussels of different sizes. This design greatly improves the adaptability and flexibility of the equipment, enabling it to efficiently process mussels of different sizes.

[0047] After quantitative separation, the mussels are conveyed to the surface of the conveyor belt 6 through the discharge pipe 23. The conveyor belt 6 is driven by the drive roller 7, smoothly conveying the mussels to the next processing stage. During the conveying process, the spreading mechanism 5 can further ensure that the mussels are evenly distributed on the surface of the conveyor belt 6, avoiding accumulation and blockage.

[0048] The entire separation process is carried out under automated control of the equipment, making operation simple and stable. In particular, the function of quickly adjusting the equipment by rotating the turntable 26 during separation not only improves processing efficiency but also reduces equipment downtime when changing different separation components. Furthermore, the coordinated design of the vibrating box 31 and the conveyor belt 6 during discharge further enhances the smoothness of mussel transport, effectively avoiding blockages during the process.

[0049] Please see the appendix Figure 2 The averaging mechanism 5 includes a drive base 51, which is located inside the frame 1. The drive base 51 is connected to a connecting rod 52 via an internal automatic electric shaft. One end of the connecting rod 52 is connected to a connecting rod 53, and one end of the connecting rod 53 is connected to a connecting block 54. Inside the connecting block 54, a rotating column 55 rotates. The outer wall of the rotating column 55 is fixed with a lifting rod 56 arranged in a ring array. The conveyor belt 6 is equipped with multiple drive rollers 7. One end of a drive roller 7 is connected to one end of the rotating column 55 via a pulley, and a belt 58 is provided. The belt 58 is equipped with a tension rod 59, and the outer wall of the tension rod 59 is in contact with the belt 58. One side of the belt 58 is equipped with an electric push rod 57 fixed on the frame 1, and the output end of the electric push rod 57 is fixed to the outer wall of the tension rod 59.

[0050] Specifically, the surface of the conveyor belt 6 is designed with evenly arranged partitions 25. These partitions 25 can separate the mussels conveyed from the discharge pipe 23 into rows, effectively preventing the mussels from piling up randomly on the conveyor belt 6, thus ensuring the orderly conveying and processing of subsequent mussels. However, for some mussels that accumulate during the conveying process, the system is also equipped with a clever dispersion structure. When the conveyor belt 6 is running, the drive roller 7 it relies on not only drives the conveyor belt 6 forward, but also drives the rotating column 55 to rotate synchronously through the belt 58. The rotation of the rotating column 55 will cause the picking rod 56 set on it to swing and pick continuously, quickly breaking up the piled mussels, avoiding large-area accumulation that affects the smoothness of the conveying, thus achieving stable dispersion and conveying of mussels.

[0051] To accommodate mussels of different sizes, the height of this dispersing device is flexibly adjustable, and the adjustment mechanism is achieved through the drive base 51. When it is necessary to change the height of the second rotating column 55, the drive base 51 will rotate via the drive connecting rod 52, changing the tilt angle of the connecting rod 52 with the drive base 51 as the center. The change in the angle of the connecting rod 52 will further affect the movement of the second connecting rod 53. Due to the connection between the two, the second connecting rod 53 will move in a synchronous pushing and pulling motion. This movement will directly drive the connecting block 54, thereby causing the second rotating column 55 to be raised and lowered as a whole, realizing the height change of the dispersing device.

[0052] Through the aforementioned adjustment functions, the height and angle of the propelling rod 56 can be flexibly adjusted according to the size and shape of the mussels, making the dispersing action more precise and efficient. For example, for larger mussels, increasing the height allows the propelling rod 56 to better contact and disperse the piled mussels; while for smaller mussels, lowering the height of the propelling rod 56 can prevent the propelling action from being too violent and causing the mussels to be scattered. This design ensures that regardless of the size of the mussels, the pile-up phenomenon can be effectively dispersed without interfering with the normal conveyor belt 6.

[0053] It is worth mentioning that this dispersing mechanism operates smoothly and precisely. Combined with the uniform separation plate 25 of the conveyor belt 6, it makes the mussel transport process more efficient. In actual operation, regardless of the size of the mussels or the transport speed, the dispersing device can respond quickly, breaking up the piled mussels through the flexible movement of the lifting rod 56, ultimately ensuring the stability and continuity of the entire transport process. At the same time, the adjustment method of this mechanism is simple and easy to operate, which can greatly reduce the frequency of manual intervention and improve the overall automation level and processing efficiency of the equipment.

[0054] Please see the appendix Figure 1 Appendix Figure 5 and attached Figure 6 The frame 1 is equipped with an electric door 9 controlled by an electric guide rail on one side. The shell removal mechanism 3 includes a vibrating box 31. An air tank 32 is fixed on one side of the vibrating box 31. An air pump is installed inside the air tank 32 and is connected to an air pressure block 33 through an air pipe. The air pressure block 33 is arc-shaped and the air port is located directly above the vibrating box 31. An oscillating plate 34 with a certain tilt angle slides inside the vibrating box 31. A second motor 35 is installed on one side of the vibrating box 31. A first gear 36 is fixed to the output end of the second motor 35 through a rotating shaft. A second gear 37 is installed on one side of the first gear 36. The first gear 36 and the second gear 37 mesh with each other. A second turntable 38 is connected to the second gear 37 through a rotating shaft. A connecting plate 39 is connected to the area of ​​the second turntable 38 away from the center through a rotating shaft. One end of the connecting plate 39 is connected to one side of the oscillating plate 34 through a rotating shaft.

[0055] Specifically, the frozen mussels are conveyed to the vibration chamber 31 via conveyor belt 6, eventually landing above the vibration plate 34. At this point, motor 35 starts, driving the entire vibration mechanism into operation. The power of motor 35 is transmitted to gear 37 via gear 36, causing gear 37 to rotate in the opposite direction. The movement of gear 37 further drives turntable 38 to rotate synchronously. Due to the eccentric design of turntable 38, its rotation causes the ends of connecting plate 39 to reciprocate. This pulling action causes the vibration plate 34 to vibrate in the up-down or left-right directions, thus ensuring the effective movement of the vibration plate 34.

[0056] As the vibrating plate 34 vibrates back and forth, the mussels on its surface are subjected to a certain amount of impact and vibration. This vibration gradually separates the shells from the meat of the frozen mussels, achieving the final shell removal effect. During the vibration process, the mussel shells are peeled off due to the vibration force, while the mussel meat remains intact and slides along the tilt angle of the vibrating plate 34. The tilted design ensures that the mussels can slide smoothly after separation, without remaining or piling up due to the planar movement of the vibrating plate 34.

[0057] Meanwhile, the tilt angle of the vibrating plate 34 allows the separated mussel meat and shells to naturally slide to the lower part of the plate during vibration. As the vibrating plate 34 continues to vibrate under the eccentric motion of the turntable 38, the separated mussels slide down the inclined surface into the collection box 8 for collection. The design of the collection box 8 makes the subsequent sorting and collection of mussel shells and meat more efficient, and the entire process is fully automated without manual intervention.

[0058] This shell-removal design is not only compact and stable in operation, but also enables efficient processing of mussels of different sizes and hardnesses. The airtight design of the vibration chamber 31, combined with the tilting and vibration functions of the vibration plate 34, ensures that the mussels will not bounce or scatter during vibration, while also preventing external interference with separation efficiency. Furthermore, through the optimized transmission ratio of gear 1 36 and gear 2 37, the frequency and amplitude of the vibration of the vibration plate 34 can be precisely controlled, thereby adapting to the shell-meat separation requirements of different mussels and further improving the adaptability and efficiency of the equipment.

[0059] The entire shelling process operates smoothly and efficiently. In particular, the back-and-forth vibration generated by the vibrating plate 34 in conjunction with the connecting plate 39 ensures thorough shelling while maximizing the preservation of the mussel meat's integrity. Finally, the separated mussel meat is quickly collected into the receiving box 8, successfully completing the separation of shell and meat. This precise design and efficient working principle provide a solid technical guarantee for the operation of the entire equipment, while greatly reducing the need for manual operation and significantly improving production efficiency.

[0060] Please see the appendix Figure 2 and attached Figure 7 The refrigeration mechanism 4 includes an electric push rod 42, which is installed inside the frame 1. A sealing door 41 is fixed to the output end of the electric push rod 42. The sealing door 41 slides inside the frame 1 and the two sealing doors 41 can be closed together. A compressor 43 is installed inside the frame 1. The compressor 43 is connected to a condenser 44 through a gas pipe. The condenser 44 has multiple rows of condenser pipes inside and is connected to an expansion valve 45 through a gas pipe. The expansion valve 45 is connected to an evaporator 46 through a gas pipe.

[0061] Specifically, after the mussels are sorted, the equipment moves to the next step. At this point, the electric push rod 42 is activated, pushing the closed door 41 to slide smoothly along the slide rail. This design ensures that the sorted mussels are evenly transported to the conveyor belt 6 in batches. The conveyor belt 6 precisely transports the mussels to the position of the refrigeration mechanism 4 inside the frame 1. The entire process is highly automated, runs smoothly, and avoids the unevenness and errors that may be caused by manual intervention.

[0062] Once a batch of mussels arrives at the processing area of ​​the refrigeration unit 4, the sealing door 41 closes again under the action of the electric push rod 42, forming a sealed space and creating an ideal working environment for the subsequent refrigeration process. At this stage, the refrigeration system begins to operate, and its core working principle is based on the cyclical refrigerant change process.

[0063] First, low-temperature, low-pressure refrigerant vapor is drawn into the compressor 43 from the evaporator 46, where it is compressed into high-temperature, high-pressure superheated vapor. Subsequently, this high-temperature, high-pressure refrigerant vapor enters the condenser 44, where it exchanges heat with an external cooling medium such as air or cooling water. Through heat exchange, the refrigerant vapor releases a large amount of heat and condenses into a high-pressure liquid state. This process is not only efficient but also stable, providing a foundation for subsequent refrigeration stages.

[0064] Next, the high-pressure liquid refrigerant passes through the expansion valve 45. The throttling effect of the expansion valve 45 rapidly reduces the refrigerant pressure, transforming it into a low-temperature, low-pressure liquid-gas mixture. This low-temperature, low-pressure refrigerant is then returned to the evaporator 46. In the evaporator 46, the refrigerant absorbs heat from the surrounding mussels and their environment, gradually vaporizing completely into low-pressure vapor, which is then drawn back into the compressor 43 to enter the next cycle.

[0065] This cyclical process rapidly lowers the temperature of the cooling zone through efficient heat transfer, quickly freezing the mussels. The advantage of rapid freezing is that the connecting tissue between the mussel shell and the flesh contracts rapidly under low temperatures due to thermal expansion and contraction, thus achieving natural separation of the shell and flesh. This method not only improves separation efficiency but also effectively maintains the quality and freshness of the mussel meat.

[0066] The entire refrigeration and shelling process is highly efficient and automated, and each step reflects rigorous mechanical design and the application of thermodynamic principles, greatly improving the efficiency and quality of mussel processing. At the same time, the airtightness and precision of this structure ensure consistent refrigeration performance, avoiding unnecessary energy consumption due to heat loss.

[0067] Example 2: Automated Control System for Mussel Shelling Device

[0068] System Composition

[0069] The control system consists of the following modules:

[0070] Central control module (PLC) or industrial controller: As the core control unit, it is used to receive sensor signals, analyze data, and issue control commands to drive the actuators to operate.

[0071] The detection module includes temperature sensors, pressure sensors, position sensors, and weight sensors, which are used to collect operational data in real time during the mussel processing.

[0072] The execution module includes an electric push rod, a second motor, a compressor 43, a condenser 44, an expansion valve 45, an evaporator 46, and a conveyor belt 6 and a drive roller 7, which complete specific operation actions.

[0073] Display and Alarm Module: Provides visual monitoring of system operating status and issues alarm signals in abnormal situations.

[0074] After the mussels enter the portioning tank 22 from the feed hopper 21, the weight sensor monitors the weight of the mussels in the tank in real time. When the detected weight reaches a set value, such as 2 kg, the weight sensor sends a signal to the central control module. After receiving the signal, the central control module issues a command to start motor 27, which drives the rotating column 24 to rotate, and works with the separator 25 to separate the mussels into uniform batches.

[0075] Judgment conditions:

[0076] Weight sensor signal > preset value 2 kg: Start motor 27.

[0077] Weight sensor signal < preset value: Wait for mussels to be filled.

[0078] After separation, the separated mussels enter conveyor belt 6 through discharge pipe 23. A position sensor detects that the mussels have entered conveyor belt 6 and sends a confirmation signal to the central control module. At this time, the drive roller 7 of conveyor belt 6 starts operating, transporting the mussels to the cooling mechanism 4 inside the frame 1.

[0079] 2. Mussel freezing control of refrigeration mechanism 4

[0080] After the mussels are transported to the refrigeration unit 4, the position sensor detects that the mussels have arrived in the refrigeration area and sends a signal to the central control module. The central control module then issues a command to drive the electric push rod 42 to close the sealing door 41, creating a sealed refrigeration environment.

[0081] After the refrigeration system is started, compressor 43 begins to work, and low-temperature, low-pressure refrigerant vapor is drawn into evaporator 46 and compressed into high-temperature, high-pressure superheated vapor. Condenser 44 converts the vapor into a high-pressure liquid, which is then depressurized through expansion valve 45, becoming a low-temperature, low-pressure liquid-gas mixture. Evaporator 46 absorbs heat from the mussels, rapidly freezing them.

[0082] Temperature sensors are installed in the evaporator 46 and the refrigeration chamber to monitor the temperature of the refrigeration chamber in real time. When the temperature drops to a preset value, such as -25°C, the temperature sensor sends a signal to the central control module, which then controls the compressor 43 to reduce its power or stop working to maintain a constant temperature inside the refrigeration chamber.

[0083] Judgment conditions:

[0084] Temperature sensor signal > -25℃: Compressor 43 is working.

[0085] Temperature sensor signal ≤-25℃: Compressor 43 stops working and enters constant temperature state.

[0086] After freezing is complete, the central control module instructs the electric push rod 42 to reopen the sealing door 41, and the conveyor belt 6 starts to transport the frozen mussels to the equalization mechanism 5.

[0087] 3. Shelling and distribution control

[0088] After the frozen mussels are conveyed to the equalization mechanism 5, the vibrating plate 34 of the vibrating box 31 is activated by the motor 35, generating high-frequency vibrations to evenly distribute the mussels on the surface of the conveyor belt 6. This process ensures that the mussels are neatly arranged when they enter the shelling mechanism 3, avoiding stacking or omissions.

[0089] Judgment conditions:

[0090] The position sensor detects that the mussels have entered the equalization mechanism 5: the vibration box 31 is activated.

[0091] Conveyor belt 6 speed control signal: The central control module adjusts the rotation speed of the drive roller 7 according to the mussel batch flow rate.

[0092] After the shelling process is completed, the mussels enter the shell-removing mechanism 3. Inside the shell-removing mechanism 3, the vibrating plate 34 and the air pressure block 33 work alternately, separating the frozen mussel shells from the meat through appropriate vibration and air pressure impact. After separation, the shells and meat are transported to different collection boxes 8.

[0093] 4. System monitoring and alarms

[0094] Throughout the process, the central control module monitors the following parameters in real time:

[0095] Temperature: Temperature sensors monitor the temperature of the cooling chamber and the refrigerant.

[0096] Pressure: The pressure sensor detects the pressure in the refrigerant pipeline.

[0097] Position: Position sensors monitor the status of the closed door 41 and the conveyor belt 6.

[0098] Weight: The weight sensor monitors the weight of the material in the dispensing tank 22.

[0099] If any parameter exceeds the preset range, such as pressure exceeding the safety value, temperature failing to meet freezing requirements, or the sealing door 41 failing to close, the central control module triggers the alarm module, issuing an audible and visual alarm and automatically shutting down the machine. Simultaneously, the display module shows fault information such as "abnormal pressure" or "sealing door 41 malfunction," facilitating timely handling by operators.

[0100] Judgment conditions:

[0101] Pressure > safe range: alarm and shutdown.

[0102] Temperature not reaching the set time: alarm and shutdown.

[0103] Signal that door 41 is not closed: Conveyor belt 6 stops running, alarm triggered.

[0104] Summarize:

[0105] In this embodiment, the control system coordinates the operation of sensors and actuators through a central control module, achieving fully automated operation of the mussel shelling device. Weight sensors ensure accurate mussel separation, temperature and pressure sensors ensure efficient refrigeration, and the combination of position sensors and electric push rods enables automatic conveying and closed-loop control. The overall system not only improves processing efficiency but also features abnormal alarms and fault shutdown functions, ensuring operational safety and reliability.

[0106] Working principle: When mussels need to be shelled, all mussels should be poured in from the feed hopper 21. The mussels will then enter the distribution tank 22. At this time, motor 27 starts normally, driving the rotating column 24 via drive shaft 28. As the rotating column 24 rotates, the separator plates 25 rotate around it, separating the mussels into portions of roughly the same size. It is worth mentioning that when dealing with mussels of different sizes, based on the overall size distribution, we can also rotate turntable 26 to separate the rotating column 24 from the drive shaft 28, thus replacing it with a new rotating column 24 and separator plates 25 of a different size. After the mussels are quantitatively separated, they will be... The discharge pipe 23 conveys the mussels to the surface of the conveyor belt 6. At this time, the partition plate 25 on the surface of the conveyor belt 6 will divide the conveyed mussels into rows. Some of the accumulated mussels can be dispersed by the pulley driven by the drive roller 7 driven by the conveyor belt 58, which drives the synchronously rotating column 2 55 to drive the picking rod 56, so that they do not pile up and can be smoothly conveyed by the conveyor belt 6. In addition, for different sizes of mussels, the corresponding drive seat 51 can drive the connecting rod 1 52 to rotate around the drive source of the drive seat 51, so that the connecting rod 2 53 changes synchronously due to the change of the tilt angle of the connecting rod 1 52, thereby making the pushing of the connecting rod 1 52 and the connecting rod 2 53... Pulling allows the connecting block 54 to drive the rotating column 55 to adjust its height, thus accommodating mussels of different sizes and allowing for more efficient handling when breaking up their piles. After the mussels are sorted, the electric push rod 42 drives the sealing door 41 to slide, thus transporting batches of mussels to the refrigeration mechanism 4 inside the frame 1 via the conveyor belt 6. The sealing door 41 is then closed by the electric push rod 42. At this point, low-temperature, low-pressure refrigerant vapor is drawn from the evaporator 46 into the compressor 43, where it is compressed into high-temperature, high-pressure superheated vapor. This high-temperature, high-pressure refrigerant vapor enters the condenser 44, where it exchanges heat with the external cooling medium, such as air or water, releasing heat and condensing into a high-pressure liquid. When the liquid refrigerant flows through the expansion valve 45, its pressure rapidly decreases due to the throttling effect, becoming a low-temperature, low-pressure liquid-gas mixture. This low-temperature, low-pressure refrigerant enters the evaporator 46, absorbs heat from the cooled medium, and completely vaporizes into low-pressure vapor, returning to the compressor 43. This cycle continues to achieve a cooling effect. At this time, the mussels are rapidly frozen, causing the shells to separate quickly from the meat. After freezing, the mussels continue to be transported by the conveyor belt 6. The electric door 9 opens, allowing the batch of frozen mussels to be transported to the vibrating chamber 31 and placed on the vibrating plate 34. At this point, the second motor 35 starts, causing the first gear 36 to rotate the second gear 37 in the opposite direction. The second gear 37 then drives the second turntable 38 to rotate synchronously.This causes the connecting plate 39 to be pulled at an eccentric position relative to the turntable 38. Both ends of the connecting plate 39 rotate to a certain extent, ensuring the normal operation of the turntable 38 and the vibrating plate 34. At this point, the mussels on the vibrating plate 34 are vibrated, resulting in the final separation of the shell and meat. Finally, due to the inclined design of the vibrating plate 34, the mussels fall into the collection box 8 as the plate is pulled and vibrated back and forth.
