Description

Technical Field

[0001] The utility model relates to the technical field of oyster shelling, and more specifically, to a full-automatic oyster shelling machine. Background Art

[0002] At present, the shelling of oysters is basically carried out manually, which is not only time-consuming and laborious, but also may cause pollution to the oyster meat. At present, some oyster automatic shelling machines have also emerged, which use machines to replace manual labor to shell oysters, thereby reducing the use of manpower, improving the shelling efficiency, and avoiding pollution to the oyster meat.

[0003] For example, an oyster automatic shelling machine and an oyster shelling method disclosed in the prior art with the publication number CN113575666A include an oyster fixing mechanism, a first driving mechanism, and a shelling mechanism; the first driving mechanism can drive the shelling mechanism to move in a direction close to or away from the oyster fixing mechanism; the shelling mechanism includes a pressing needle, shelling fingers, and a second driving mechanism, and two groups of shelling fingers are respectively located on both sides of the pressing needle, and the second driving mechanism can drive the two groups of shelling fingers to approach or move away from each other.

[0004] In the above technical solution, before shelling, it is necessary to manually place the oyster on the jacking mechanism by hand, and it is necessary to manually adjust the oyster shell contact line for shelling; after shelling, it is also necessary to manually remove the oyster and manually remove the oyster meat from the oyster shell. This shelling machine requires manual participation in the operation, which is very time-consuming and laborious, and the shelling efficiency is also low. Moreover, manual workers may be scratched by the machine during the process of adjusting the oyster shell contact line, and may also be scratched by the oyster shell during the process of manually removing the oyster meat, which has a certain degree of danger. Summary of the Utility Model

[0005] Aiming at the problems in the above-mentioned prior art that oyster shelling requires manual participation, has low efficiency, and has a certain degree of danger, the utility model provides a full-automatic oyster shelling machine, which does not require manual participation throughout the process, and can improve the shelling efficiency and shelling safety.

[0006] To solve the above technical problems, the technical solution provided by the utility model is:

[0007] A full-automatic oyster shelling machine includes a shelling mechanism, and also includes a cleaning mechanism, a conveying mechanism, and a meat-taking mechanism. The discharge end of the cleaning mechanism is connected to the feed end of the conveying mechanism, the discharge end of the conveying mechanism is connected to the feed end of the shelling mechanism, and the meat-taking mechanism is used to take out the oyster meat on the shelling mechanism.

[0008] In the above technical solution, first, the oysters are poured into the cleaning mechanism, and the cleaning mechanism cleans the attachments on the surface of the oysters to prepare for opening the oyster shells; the cleaned oysters enter the feeding end of the conveying mechanism from the discharging end of the cleaning mechanism and are conveyed to the shell-opening mechanism by the conveying mechanism for shell opening; after the shell-opening mechanism opens the oyster shells, the oyster meat is exposed; finally, the meat-taking mechanism takes out the exposed oyster meat. The whole process does not require manual contact with the shell-opening mechanism and taking out the oyster meat, which can not only improve the shell-meat separation efficiency of oysters, but also improve the safety of oyster shell opening.

[0009] Preferably, the cleaning mechanism includes a first frame, a water pump, a high-pressure water gun assembly, a first rotation driving assembly and a plurality of roller brushes; the water pump and the high-pressure water gun assembly are both arranged on the first frame, the water pump is used for pumping clean water to the high-pressure water gun assembly, and a plurality of nozzles are arranged on the high-pressure water gun assembly; the plurality of roller brushes are linearly distributed along the direction perpendicular to their own axes, and the roller brushes are all rotatably connected to the first frame, and at least some of the nozzles are located above the roller brushes and face the roller brushes; the first rotation driving assembly is used for driving the roller brushes to rotate; the roller brush at the discharging end is located above the feeding end of the conveying mechanism. During implementation, the oysters are poured above the roller brush near the feeding end, and then the water pump is turned on to pump clean water to the high-pressure water gun assembly. The clean water is sprayed out through the nozzles to wash the surface of the oysters and apply a downward pressure to the oysters; at the same time, the first rotation driving assembly drives the roller brushes to rotate, and the bristles on the roller brushes will apply downward and upward component forces to the oysters, causing the oysters to roll, so that both sides of the oyster shells can be brushed by the bristles and impacted by the high-pressure water; at the same time, the bristles on the roller brushes will apply a horizontal thrust to the oysters, causing the oysters to roll and move forward at the same time, and finally fall from the roller brush at the discharging end to the feeding end of the conveying mechanism. The high-pressure water can penetrate into the tiny unevenness and inaccessible corners on the surface of the oyster shells, thoroughly removing the sediment, seaweed and other dirt attached to the shells. Combined with the roller brushes, the impurities remaining on the surface of the oyster shells can be thoroughly removed. Such a cleaning mechanism has a high cleaning efficiency and a higher cleanliness of the cleaned oysters.

[0010] Preferably, the conveying mechanism includes a second frame, an arranging assembly and a conveyor belt conveying assembly; the arranging assembly includes a second rotation driving assembly, a supporting disk and a rotating conical disk arranged on the second frame, the rotating conical disk is rotatably connected to the supporting disk with its own axis as the rotation axis, a blocking ring is arranged on the outer edge of the supporting disk, and an accommodating cavity for accommodating oysters is formed between the blocking ring and the rotating conical disk.

[0011] Further, a notch communicating with the accommodation cavity is provided on the blocking ring, and the notch is located above the feeding end of the conveyor belt conveying assembly; a first guide plate is provided on one side of the notch, and the first guide plate extends towards the inside of the support plate; a baffle and a second guide plate are provided on the other side of the notch, the baffle extends towards the inside of the support plate, and a space for a single oyster to pass through is formed between the baffle and the support plate; the second guide plate extends towards the outside of the support plate and its extending direction is the same as the conveying direction of the conveyor belt conveying assembly. During implementation, the second rotation driving assembly drives the rotating cone plate to rotate, and the oysters fall into the accommodation cavity from the discharging end of the cleaning mechanism and move along the accommodation cavity with the rotation of the rotating cone plate. The centrifugal force of rotation will cause the oysters to have a tendency to be thrown outwards, and the blocking ring can prevent the oysters from falling out of the support plate. When the oysters move to the notch on the blocking ring, the oysters move upwards along the first guide plate onto the rotating cone plate and then roll down to contact the second guide plate, and the oysters located above this oyster will be blocked by the baffle and return to the support plate along the baffle; the oysters in contact with the second guide plate will move along the second guide plate to the feeding end of the conveyor belt conveying assembly and be conveyed to the feeding end of the shelling mechanism through the conveyor belt conveying assembly. By providing the first guide plate and the baffle, the oysters located on the side and above a single oyster can be blocked, ensuring that the oysters can be output individually, and the second guide plate can ensure that the oysters always fall at the same position on the conveyor belt conveying assembly, enabling the oysters to be conveyed in a single row.

[0012] Preferably, the shelling mechanism includes a third frame and a fixture provided on the third frame. The fixture includes a base, a top plate, a movable plate and a third rotation driving assembly provided on the third frame; a first translation driving assembly, a second translation driving assembly, a first gripper and a second gripper for clamping oysters are provided on the base, and the first translation driving assembly and the second translation driving assembly are respectively used to drive the first gripper and the second gripper to move horizontally; the top plate is located above the base and is connected to the base; the movable plate is located between the base and the top plate and is slidably connected to the top plate along the vertical direction; a shelling cone head is provided on the top plate, the shelling cone head is threadedly connected to the top plate and is rotatably connected to the movable plate, and the tip of the shelling cone head extends out of the bottom end of the movable plate; the third rotation driving assembly is used to drive the shelling cone head to rotate with its own axis as the rotation axis; a third translation driving assembly, a fourth translation driving assembly, a first shelling finger and a second shelling finger for prying open oysters are provided on the movable plate, and the third translation driving assembly and the fourth translation driving assembly are respectively used to drive the first shelling finger and the second shelling finger to move horizontally; the meat-taking mechanism is used to take out the oyster meat between the first gripper and the second gripper.

[0013] During implementation, when the oyster is conveyed by the conveyor belt conveying component to the base and is located between the first gripper and the second gripper, the first gripper and the second gripper are driven to move towards each other by the first translation driving component and the second translation driving component, so that the oyster changes from a flat state to an upright state and is clamped; then the third rotation driving component drives the shell opening cone head to rotate, so that the shell opening cone head and the movable plate descend simultaneously, and the shell opening cone head is used to drill into the interior of the oyster shell; after a gap appears in the oyster shell, both the first shell opening finger and the second shell opening finger extend into the gap, and the shell opening cone head stops rotating; then the third translation driving component and the fourth translation driving component drive the first shell opening finger and the second shell opening finger to move away from each other, thereby opening the oyster, and thus the shell opening of the oyster is completed.

[0014] Preferably, an industrial camera is provided at the discharge end of the conveyor belt conveying component, and the industrial camera is electrically connected to the third translation driving component and the fourth translation driving component respectively. The industrial camera continuously takes pictures and relies on the vision system to feedback signals to the third translation driving component and the fourth translation driving component, so that the first gripper and the second gripper clamp and continuously adjust the centering of the oyster, ensuring that the line on the side of the oyster shell is aligned with the tip of the shell opening cone head to reduce the shell opening resistance.

[0015] Preferably, a limiting V-shaped groove is provided on the top surface of the base, the limiting V-shaped groove is located between the first gripper and the second gripper, and the tip of the shell opening cone head is aligned with the limiting V-shaped groove. The limiting V-shaped groove can limit the swing of the side of the oyster, which is beneficial to improving the centering speed of the oyster and the shell opening cone head and the shell opening efficiency of the oyster.

[0016] Preferably, a photosensitive sensor is provided at the bottom of the movable plate, the photosensitive sensor is located on one side of the shell opening cone head, and the third rotation driving component, the third translation driving component and the fourth translation driving component are all electrically connected to the photosensitive sensor. When the photosensitive sensor enters the interior of the oyster along with the shell opening cone head, due to the change of light, the photosensitive sensor will send a signal to the third rotation driving component to make the third rotation driving component stop driving the shell opening cone head to rotate. At the same time, the photosensitive sensor will also send a signal to the third translation driving component and the fourth translation driving component to make the third translation driving component and the fourth translation driving component drive to increase the distance between the first shell opening finger and the second shell opening finger. The photosensitive sensor can send signals to the third rotation driving component, the third translation driving component and the fourth translation driving component according to the shell opening situation of the oyster, so that the shell opening cone head, the first shell opening finger and the second shell opening finger make corresponding actions in time, thereby improving the shell opening efficiency.

[0017] Preferably, the meat-taking mechanism comprises a vacuum suction pipe, a fifth translation driving assembly, a collection tank and a vacuum generator; the fifth translation driving assembly is arranged on the third rack and is used for driving the inlet end of the vacuum suction pipe to move between the first clamp and the second clamp; the outlet end of the vacuum suction pipe is communicated with the inner cavity of the collection tank; the collection tank comprises a tank body and a tank door, the tank door is arranged at the bottom of the tank body, one side of the tank door is rotatably connected with the tank body, and the other side is connected with the tank body through a spring; the vacuum generator is communicated with the collection tank. During implementation, a water tank filled with water is placed below the tank door; the vacuum generator works to generate negative pressure inside both the collection tank and the vacuum suction pipe, and the tank door is closed under the action of the negative pressure; the fifth translation driving assembly drives the vacuum suction pipe to extend out, so that the inlet end of the vacuum suction pipe approaches and aligns with the oyster meat on the oyster shell, and the oyster meat is sucked into the collection tank. In order to prevent the oyster meat from being damaged due to accumulation in the collection tank, the vacuum generator works intermittently. When the vacuum generator stops working, the tank door opens and forms an opening with the tank body, and the oysters leave the collection tank through the opening. The distance between the tank body and the tank door is restricted by the spring to ensure that the size of the opening formed between the tank body and the tank door can vary with the weight of the oyster meat. The oysters leaving the collection tank enter the water tank filled with water, and the water in the tank buffers the momentum of the falling oyster meat to ensure that the obtained oyster meat is in a perfect state.

[0018] Preferably, a shelling mechanism is further included, the shelling mechanism comprises an air pump and a blowing pipe, the blowing pipe is communicated with the air pump, and the blowing pipe is used for blowing the oyster shell between the first clamp and the second clamp away from the base. After the vacuum suction pipe sucks the oyster meat on the oyster shell, the air pump pumps gas into the blowing pipe, and the blowing pipe is used to blow the oyster shell between the first clamp and the second clamp away from the fixture.

[0019] Preferably, a fourth rotary drive assembly and a turntable are provided on the third rack. The fourth rotary drive assembly is used to drive the turntable to rotate about its own axis, and at least three clamps are provided and evenly distributed along the edge of the turntable; the conveying direction of the discharge end of the conveying mechanism forms a 120° angle with the air inlet direction of the inlet end of the vacuum suction pipe and the air outlet direction of the outlet end of the blowing pipe respectively, and the air inlet direction of the inlet end of the vacuum suction pipe and the air outlet direction of the outlet end of the blowing pipe form a 120° angle. After opening the shell of an oyster, the fourth rotary drive assembly drives the turntable to rotate 120°, so that the clamp where the oyster is located moves to the position where the vacuum suction pipe is located, and then the vacuum suction pipe sucks the oyster meat on the oyster; subsequently, the fourth rotary drive assembly drives the turntable to rotate 120° again, so that the clamp where the oyster is located moves to the position where the blowing pipe is located, and the oyster is blown off the clamp through the blowing pipe. Every time the turntable rotates 120°, an oyster enters one of the clamps. At the same time, the oyster on one clamp is being de-meated, and the oyster on another clamp is being blown off the clamp. Through such a layout, the shelling, de-meating and shell-removing of oysters can be carried out simultaneously, thereby effectively improving the processing efficiency of oysters.

[0020] Advantages of the utility model:

[0021] (1) Integrating the functions of oyster cleaning, oyster shelling and oyster meat collection, the full automation of oyster shelling can be realized without manual participation, which can not only reduce the labor cost and improve the shelling efficiency of oysters, but also improve the safety of oyster shelling.

[0022] (2) The cleaning mechanism combines a high-pressure water gun assembly and a roller brush to wash and brush the oysters, which not only has a high cleaning efficiency, but also can thoroughly remove the impurities remaining on the surface of the oyster shell.

Such a shelling mechanism has a high shelling efficiency and can greatly protect the integrity of the oyster shell, avoiding the pollution or damage to the oyster meat caused by the broken oyster shell.

[0025] (5) The de-meating mechanism intermittently sucks the oyster meat into the collection tank by using a vacuum suction pipe. When the oyster reaches a certain weight, the tank door of the collection tank will automatically open, so that the oyster falls into the water tank, thereby obtaining intact oyster meat.

[0026] (6) A shelling mechanism is provided. The shelling mechanism blows off the oyster shells on the shell-opening mechanism through a blowing pipe, eliminating the need for manual removal of the oyster shells. Description of the Drawings

The discharge end of the cleaning mechanism 2 is connected to the feed end of the conveying mechanism 3, and the discharge end of the conveying mechanism 3 is connected to the feed end of the shelling mechanism 1. The meat-taking mechanism 4 is used to take out the oyster meat on the shelling mechanism 1.

[0042] The working principle or working process of this embodiment: First, pour the oysters into the cleaning mechanism 2, and clean the attachments on the surface of the oysters through the cleaning mechanism 2 to prepare for shelling the oysters; the cleaned oysters enter the feed end of the conveying mechanism 3 from the discharge end of the cleaning mechanism 2 and are conveyed to the shelling mechanism 1 by the conveying mechanism 3 for shelling; after the shelling mechanism 1 shells the oysters, the oyster meat is exposed; finally, the meat-taking mechanism 4 takes out the exposed oyster meat.

During implementation, the oysters are poured above the roller brush 9 near the feed end, and then the water pump 6 is turned on to pump clear water to the high-pressure water gun assembly 7, and the clear water is sprayed out through the nozzles 701 to wash the surface of the oysters and apply a downward pressure to the oysters; at the same time, the first rotary drive assembly 8 drives the roller brush 9 to rotate, and the bristles on the roller brush 9 will apply downward and upward component forces to the oysters, causing the oysters to roll, so that both sides of the oyster shell can be brushed by the bristles and impacted by the high-pressure water; at the same time, the bristles on the roller brush 9 will apply a horizontal thrust to the oysters, causing the oysters to roll and move forward at the same time, and finally fall from the roller brush 9 at the discharge end to the feed end of the conveying mechanism 3. The high-pressure water can penetrate into the tiny unevenness and inaccessible corners on the surface of the oyster shell, thoroughly removing the sediment, seaweed, and other dirt attached to the shell. Combined with the roller brush 9, the impurities remaining on the surface of the oyster shell can be thoroughly removed.

During implementation, the second rotation drive assembly 11 drives the rotary cone disc 13 to rotate, and the oysters fall into the accommodation cavity 1401 from the discharge end of the cleaning mechanism 2 and move along the accommodation cavity 1401 as the rotary cone disc 13 rotates. The centrifugal force of rotation will cause the oysters to have a tendency to be thrown outwards, while the blocking ring 14 can prevent the oysters from falling out of the support disc 12. When the oysters move to the notch 1402 on the blocking ring 14, the oysters move upwards along the first guide plate 15 onto the rotary cone disc 13 and then roll down to contact the second guide plate 17, and the oysters located above this oyster will be blocked by the baffle 16 and return to the support disc 12 along the baffle 16; the oysters in contact with the second guide plate 17 will move along the second guide plate 17 to the feeding end of the conveyor belt conveying assembly 18 and be conveyed to the feeding end of the shell opening mechanism 1 through the conveyor belt conveying assembly 18. By providing the first guide plate 15 and the baffle 16, the oysters located on the side and above a single oyster can be blocked, ensuring that the oysters can be output individually, while the second guide plate 17 can ensure that the oysters always fall at the same position on the conveyor belt conveying assembly 18, enabling the oysters to be conveyed in a single row.

[0050] Specifically, a plurality of first enclosing plates 2601 are arranged on the side of the first gripper 26 close to the second gripper 27, and the first enclosing plates 2601 all extend outwards. The plurality of first enclosing plates 2601 enclose a first limiting cavity for accommodating oysters; a plurality of second enclosing plates 2701 are arranged on the side of the second gripper 27 close to the first gripper 26, and the second enclosing plates 2701 all extend outwards.

In this way, when the first gripper 26 and the second gripper 27 grip oysters, the oysters can be kept in a relatively stable state and are not easily offset or rolled over.

[0051] During implementation, when the oyster is conveyed to the base 20 by the conveyor belt conveying assembly 18 and is located between the first gripper 26 and the second gripper 27, the first translation drive assembly 24 and the second translation drive assembly 25 drive the first gripper 26 and the second gripper 27 to move towards each other, changing the oyster from a flat state to an upright state and clamping the oyster; then the third rotation drive assembly 23 drives the shell-opening cone head 28 to rotate, causing the shell-opening cone head 28 and the movable plate 22 to descend simultaneously, and using the shell-opening cone head 28 to drill into the interior of the oyster shell; after a gap appears in the oyster shell, both the first shell-opening finger 31 and the second shell-opening finger 32 extend into the gap, and the shell-opening cone head 28 stops rotating; then the third translation drive assembly 29 and the fourth translation drive assembly 30 drive the first shell-opening finger 31 and the second shell-opening finger 32 to move away from each other, thereby opening the oyster, and thus completing the shell-opening of the oyster.

[0052] Furthermore, an industrial camera 33 is provided at the discharge end of the conveyor belt conveying assembly 18. The industrial camera 33 is electrically connected to the third translation drive assembly 29 and the fourth translation drive assembly 30 respectively. The industrial camera 33 continuously takes pictures and relies on the vision system to feedback signals to the third translation drive assembly 29 and the fourth translation drive assembly 30, causing the first gripper 26 and the second gripper 27 to clamp and continuously adjust to center the oyster, ensuring that the line on the side of the oyster shell is aligned with the tip of the shell-opening cone head 28 to reduce the shell-opening resistance.

[0053] Furthermore, a limiting V-shaped groove 2001 is provided on the top surface of the base 20. The limiting V-shaped groove 2001 is located between the first gripper 26 and the second gripper 27, and the tip of the shell-opening cone head 28 is aligned with the limiting V-shaped groove 2001. The limiting V-shaped groove 2001 can limit the swing of the side of the oyster, which is beneficial to improving the centering speed of the oyster and the shell-opening cone head 28 and the shell-opening efficiency of the oyster.

[0054] Furthermore, a photosensitive sensor 34 is provided at the bottom of the movable plate 22. The photosensitive sensor 34 is located on one side of the shell-opening cone head 28. The third rotation drive assembly 23, the third translation drive assembly 29, and the fourth translation drive assembly 30 are all electrically connected to the photosensitive sensor 34. When the photosensitive sensor 34 enters the interior of the oyster along with the shell-opening cone head 28, due to the change in light, the photosensitive sensor 34 will send a signal to the third rotation drive assembly 23 to cause the third rotation drive assembly 23 to stop driving the shell-opening cone head 28 to rotate. At the same time, the photosensitive sensor 34 will also send a signal to the third translation drive assembly 29 and the fourth translation drive assembly 30 to cause the third translation drive assembly 29 and the fourth translation drive assembly 30 to drive and increase the distance between the first shell-opening finger 31 and the second shell-opening finger 32. The photosensitive sensor 34 can send signals to the third rotation drive assembly 23, the third translation drive assembly 29, and the fourth translation drive assembly 30 according to the shell-opening situation of the oyster, enabling the shell-opening cone head 28, the first shell-opening finger 31, and the second shell-opening finger 32 to make corresponding actions in a timely manner, thereby improving the shell-opening efficiency.

[0055] Other features, working principles, and beneficial effects of this embodiment are the same as those of Embodiment 1.

[0056] Embodiment 3

[0057] Based on Embodiment 2, as Figure 1 、 Figure 5 and Figure 9 shown, further, the meat-taking mechanism 4 includes a vacuum suction pipe (not shown in the figure), a fifth translation drive assembly 35, a collection tank 36, and a vacuum generator 37; the fifth translation drive assembly 35 is a cylinder, which is arranged on the third rack 19 and is used to drive the inlet end of the vacuum suction pipe to move between the first gripper 26 and the second gripper 27; the outlet end of the vacuum suction pipe is communicated with the inner cavity of the collection tank 36; the collection tank 36 includes a tank body 3601 and a tank door 3602, the tank door 3602 is arranged at the bottom of the tank body 3601, one side of which is rotatably connected to the tank body 3601, and the other side is connected to the tank body 3601 through two springs 3603; the vacuum generator 37 is communicated with the collection tank 36. During implementation, a water tank filled with water is placed below the tank door 3602; the vacuum generator 37 works to generate negative pressure inside both the collection tank 36 and the vacuum suction pipe, and the tank door 3602 closes under the action of the negative pressure; the fifth translation drive assembly 35 drives the vacuum suction pipe to extend, so that the inlet end of the vacuum suction pipe approaches and aligns with the oyster meat on the oyster shell, and sucks the oyster meat into the collection tank 36. In order to prevent the oyster meat from being damaged due to accumulation in the collection tank 36, the vacuum generator 37 works intermittently. When the vacuum generator 37 stops working, the tank door 3602 opens and forms an opening with the tank body 3601, and the oyster leaves the collection tank 36 through this opening. The distance between the tank body 3601 and the tank door 3602 is restricted by the springs 3603 to ensure that the size of the opening formed between the tank body 3601 and the tank door 3602 can vary with the weight of the oyster meat. The oyster leaving the collection tank 36 enters the water tank filled with water, and the water in the tank buffers the momentum of the oyster meat falling, ensuring that the obtained oyster meat is in a completely intact state.

[0058] Further, it also includes a shelling mechanism. The shelling mechanism includes an air pump 38 and a blowing pipe 39. The blowing pipe 39 is communicated with the air pump 38, and the blowing pipe 39 is used to blow the oyster shell between the first gripper 26 and the second gripper 27 away from the base 20. After the vacuum suction pipe sucks the oyster meat on the oyster shell, the air pump 38 pumps gas into the blowing pipe 39, and uses the blowing pipe 39 to blow the oyster shell between the first gripper 26 and the second gripper 27 away from the fixture.

[0059] Further, a fourth rotation drive assembly 40 and a turntable 41 are provided on the third rack 19. The fourth rotation drive assembly 40 is configured to drive the turntable 41 to rotate about its own axis. There are three clamps which are evenly distributed along the edge of the turntable 41. The conveying direction of the discharge end of the conveying mechanism 3 forms a 120° angle with the air intake direction of the inlet end of the vacuum suction pipe and the air outlet direction of the outlet end of the blowing pipe 39 respectively. The air intake direction of the inlet end of the vacuum suction pipe and the air outlet direction of the outlet end of the blowing pipe 39 form a 120° angle. After an oyster is shelled, the fourth rotation drive assembly 40 drives the turntable 41 to rotate 120°, so that the clamp where the oyster is located moves to the position where the vacuum suction pipe is located, and then the vacuum suction pipe sucks the oyster meat on the oyster. Subsequently, the fourth rotation drive assembly 40 drives the turntable 41 to rotate 120° again, so that the clamp where the oyster is located moves to the position where the blowing pipe 39 is located, and the oyster is blown off the clamp through the blowing pipe 39. Every time the turntable 41 rotates 120°, an oyster enters the first clamp, at the same time, the oyster on the second clamp is being de-meated, and the oyster on the third clamp is blown off the clamp. Through such an arrangement, the shelling, de-meating and shell-removing of oysters can be carried out simultaneously, thereby effectively improving the processing efficiency of oysters.
