Description

Technical Field

[0001] This invention relates to a shell-opening device for bivalve mollusks, specifically a low-temperature processing shell-opening device for bivalve mollusks, belonging to the technical field of shell-opening equipment. Background Technology

[0002] Mollusks, a type of mollusc, are triblastic, bilaterally symmetrical animals with a true coelom. The true coelom of mollusks is formed by slit-coelom formation, specifically by the mesoderm. However, the true coelom in mollusks is underdeveloped, existing only in the pericardial cavity and gonadal cavity. Mollusks exhibit great morphological variation, but structurally they can all be divided into four parts: head, foot, visceral sac, and mantle. Bivalve mollusks are a nutritious aquatic product, and most are edible. They are particularly popular in coastal areas. With improved living standards, due to their high nutritional value and delicious taste, people in central and inland regions are also increasingly consuming these aquatic products, and shellfish are gradually becoming a popular culinary food.

[0003] Currently available shellfish meat separation equipment separates the meat from the shell after the shells have automatically opened during cooking. While this makes separation easier, cooked shellfish are typically processed directly into ready-made food, limiting the options for further cooking and failing to meet the needs of restaurants and canteens for separating the meat from the shells of fresh shellfish. Existing shell-opening devices require high temperature and pressure to open the shells, but this high-temperature processing reduces the texture of the shellfish meat, affecting product quality. To ensure the texture of the shellfish meat, manual shell-opening is necessary. However, manual shell-opening is time-consuming, requires manual feeding, and is inefficient. Furthermore, the sharpness and strength of the shells pose a certain risk during the opening process. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] The purpose of this invention is to provide a low-temperature processing and shell-opening device for bivalve shellfish to solve the above-mentioned problems. This addresses the issue that high-temperature processing in the prior art reduces the texture of the shellfish meat, affecting product quality. To ensure the texture of the shellfish meat, manual shell-opening is required. However, manual shell-opening is time-consuming, requires manual feeding, and is inefficient. Furthermore, the sharpness and strength of the shells pose certain risks during the opening process.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a low-temperature processing and shell-opening device for bivalve shellfish, comprising a water tank and a processing tank.

An arc-shaped plate is fixedly connected to one side of each of the two rotating blocks. A push plate is fixedly connected to the top of each of the two arc-shaped plates. Horizontal plates are provided at the upper and lower ends of the front side of the push plate. Separation plates are integrally formed on opposite sides of each of the two horizontal plates.

[0008] Preferably, one of the support plates is fixedly connected to a forward and reverse motor on one side, and both ends of the push plate are fixedly connected to electric push rods. The output ends of the two electric push rods are fixedly connected to tapered plates. Both ends of the push plate are provided with through slots. Two connecting plates are provided on the rear side of the push plate. Both ends of the front side of the two connecting plates are fixedly connected to moving rods. The four moving rods pass through the two through slots and are slidably connected to the two through slots. The four moving rods are fixedly connected to the two horizontal plates. Both ends of the two connecting plates are formed with guide inclined plates. The two tapered plates correspond to the two guide inclined plates. The two electric push rods are activated to drive the two tapered plates to move. The movement of the two tapered plates pushes the guide inclined plates to move, which in turn drives the connecting plates to move.

[0009] Preferably, the push plate has support plates formed on both the upper and lower sides at both ends, and each of the four support plates has a sliding rod slidably connected inside. One end of each of the four sliding rods is fixedly connected to both ends of the two connecting plates, and springs are sleeved on the outer sides of each of the four sliding rods. The two ends of each of the four springs are respectively attached to the four support plates and the two connecting plates, so that the springs support and limit the support plates and connecting plates.

[0010] Preferably, a groove is provided in the middle of the platform, and an L-shaped rod is slidably connected inside the groove. A pusher plate is fixedly connected to one side of the top of the L-shaped rod. The pusher plate is in contact with the top of the supporting inclined plate. A rack is fixedly connected to the bottom of the L-shaped rod. A gear is fixedly connected to the middle of the rotating shaft. The gear meshes with the rack, so that the rotating shaft rotates and drives the gear to rotate, and the gear drives the rack to move.

[0011] Preferably, a fixing plate is fixedly connected to both sides of the top of the processing box, and a lifting hydraulic rod is fixedly connected to the top of each of the two fixing plates. The output ends of the two lifting hydraulic rods pass through both sides of the fixing plate and are slidably connected to the fixing plate. A limit plate is provided on the top of the platform, and the output ends of the two lifting hydraulic rods are fixedly connected to the top sides of the limit plate, so that the lifting hydraulic rods drive the limit plate to press down, which facilitates pressing down and fixing the shellfish.

[0012] Preferably, a connecting frame is fixedly connected between the water tank and the treatment box, and a collection box is fixedly connected inside the connecting frame. Multiple drainage holes are opened inside the multiple guide platforms. The collection box is set at the bottom of the multiple guide platforms. A pushing hydraulic rod is fixedly connected inside the collection box. The output end of the pushing hydraulic rod is fixedly connected to the support rod. The angle of the pushing hydraulic rod corresponds to the inclination of the multiple lifting plates. The pushing hydraulic rod is activated to drive the support rod to rise and fall, so that the support rod drives the multiple lifting plates to move.

[0013] Preferably, the discharge assembly includes a collection frame and a filter plate. The collection frame is located at the bottom of the pool and is adapted to the pool. The filter plate is hinged to one side of the bottom of the collection frame and is adapted to the collection frame. Both sides of the filter plate are fixedly connected with hanging ears, so that the filter plate can be deflected inside the collection frame, thereby tilting the filter plate and causing the shellfish to slide down the filter plate.

[0014] Preferably, lifting hydraulic rods are fixedly connected to both sides of the water tank, and hanging plates are fixedly connected to the output ends of the two lifting hydraulic rods. Hanging ropes are fixedly connected to the bottom of the two hanging plates, and the bottom ends of the two hanging ropes are fixedly connected to two hanging ears respectively. Guide plates are fixedly connected to the four corners of the top of the water tank. Two top plates are fixedly connected to both sides of the top of the collection frame. Guide rods are fixedly connected to the top of the four top plates. The four guide rods pass through the four top plates and are slidably connected to the four guide plates to guide the collection frame and keep the collection frame moving vertically.

[0015] Preferably, a baffle is formed on one side of the top of the collection frame, a boss is formed on the top of the baffle, and the inner side of the baffle is set in an arc shape that matches the moving trajectory of the filter plate, so that the filter plate slides along the baffle when it moves, and the boss on the top of the baffle limits the filter plate.

[0016] Preferably, a cover plate is fixedly connected to the top of the processing box, and a condenser is fixedly connected to one side of the connecting frame. The input end of the condenser is connected to the inside of the processing box to introduce cold air into the processing box and the inside of the cover plate for cooling.

[0017] This invention provides a low-temperature processing and shell-opening device for bivalve shellfish, which has the following beneficial effects:

[0018] 1. This low-temperature processing and shell-opening equipment for bivalve shellfish uses two hanging plates to suspend two ropes, which pull two hanging lugs upwards. As the lugs rise, they cause the filter plate to deflect inside the collection frame. This causes the filter plate's edge to slide along the inner side of the baffle as it deflects upwards, preventing the shellfish from falling. When the filter plate moves to be in contact with the baffle, the shellfish at the top of the filter plate slide down to the bottom as the filter plate tilts. After the filter plate contacts the baffle, the hanging ropes continue to pull the lugs, moving the filter plate and causing the collection frame to rise. After the filter plate moves the shellfish above the water surface, water mixed with impurities and silt slides down from inside the filter plate, causing the collection frame to rise to the top of the pool. As the collection frame moves, it moves the top plate, which in turn moves the guide rod inside the guide plate, guiding and limiting the collection frame to maintain a vertical upward state. This improves the stability of the collection frame's operation, facilitates automatic feeding, and increases work efficiency.

[0019] 2. This low-temperature processing and shell-opening equipment for bivalve shellfish utilizes a pusher hydraulic rod. This rod, when activated, lifts a support rod, which in turn lifts multiple lifting plates. These plates move between multiple guide platforms, raising the shellfish that have fallen onto their tops. The shellfish are then moved to the side of the next guide platform, aligning the lifting plates with the upper guide platform. The shellfish then fall to the top of the second-layer guide platform. This process is repeated continuously, with the shellfish moving upwards along the lifting plates and guide platforms. After the shellfish at the bottom layer are lifted, the shellfish accumulated on top of the guide plate are automatically replenished by gravity. This causes the lifting plates to push the shellfish upwards row by row, finally moving them along the support ramp to the top of the platform. This facilitates support and shell-opening of the shellfish, enabling automatic feeding. The arrangement of the shellfish above the platform also facilitates operation and improves work efficiency.

[0020] 3. This low-temperature processing and shell-opening equipment for bivalve shellfish uses a rotating shaft to drive two rotating blocks, which in turn drive two arc-shaped plates. These arc-shaped plates then rotate a push plate to one side of the platform, bringing it into contact with multiple shellfish. The push plate also causes two connecting plates and two horizontal plates to come into contact with the shellfish, thereby moving two separating plates into the recess between the shellfish's two shells. This activates two electric push rods, which in turn move two conical plates inward, bringing them into contact with two guide plates. The conical plates then push the two conical plates outward, causing the two connecting plates to separate, thus allowing the two connecting plates to... The two moving rods and two horizontal plates separate vertically, causing the two horizontal plates to drive the two separating plates to separate. When the two separating plates separate vertically, they separate the upper and lower shells of the shellfish for shell opening. During shell opening, a limiting plate supports the shell, causing the forward and reverse motors to start in reverse, driving the rotating shaft to reverse. The rotating shaft drives the push plate to move in the opposite direction to reset. At the same time, the rotating shaft drives the gear to rotate in the opposite direction, causing the gear to drive the rack to move. When the rack moves, it drives the pusher plate to move. The pusher plate pushes the shellfish down from the top of the platform for easy collection. This facilitates rapid shell opening and collection of shellfish, has high safety, and uses low-temperature processing to improve the taste of the shellfish meat. Attached Figure Description

A baffle 45 is formed on one side of the top of the collection frame 37. A boss is formed on the top of the baffle 45. The inner side of the baffle 45 is set as an arc shape that matches the moving trajectory of the filter plate 38, so that the filter plate 38 slides along the baffle 45 when it moves. The boss on the top of the baffle 45 limits the filter plate 38. A cover plate 47 is fixedly connected to the top of the processing box 2. A condenser 46 is fixedly connected to one side of the connecting frame 35. The input end of the condenser 46 is connected to the inside of the processing box 2 to introduce cold air into the processing box 2 and the inside of the cover plate 47 for cooling.

[0039] Multiple guide platforms 3 are fixedly connected to the inside of the processing box 2 at an incline. The guide platforms 3 are arranged in an array. A support inclined plate 4 is fixedly connected to the rear side of the processing box 2. Multiple lifting plates 5 are set inside the processing box 2 and are slidably connected between the multiple guide platforms 3. A flow guide plate 6 is fixedly connected to the front side of the processing box 2 and fits against the top of the bottom guide platform 3. A support rod 7 is set inside the processing box 2. The top of the support rod 7 is fixedly connected to the multiple lifting plates 5. A platform 8 is formed on one side of the top of the support inclined plate 4. Support plates 9 are fixedly connected to both sides of the bottom of the platform 8. A rotating shaft 10 is rotatably connected inside the two support plates 9. Rotating blocks 11 are fixedly connected to the outer sides of both ends of the rotating shaft 10. An arc plate 12 is fixedly connected to one side of each of the two rotating blocks 11. A push plate 13 is fixedly connected to the top of each of the two arc plates 12. A horizontal plate 15 is set at both the upper and lower ends of the front side of the push plate 13. A separation plate 16 is integrally formed on the opposite side of each of the two horizontal plates 15.

[0040] A connecting frame 35 is fixedly connected between the water tank 1 and the treatment box 2. A collection box 36 is fixedly connected inside the connecting frame 35. Multiple guide platforms 3 are provided with multiple drainage holes. The collection box 36 is located at the bottom of the multiple guide platforms 3. A pusher hydraulic rod 17 is fixedly connected inside the collection box 36. The output end of the pusher hydraulic rod 17 is fixedly connected to the support rod 7. The angle of the pusher hydraulic rod 17 corresponds to the inclination of the multiple lifting plates 5. The pusher hydraulic rod 17 is activated to drive the support rod 7 to rise and fall, so that the support rod 7 drives the multiple lifting plates 5 to move.

[0041] One of the support plates 9 is fixedly connected to a forward and reverse motor 18 on one side. Both ends of the rear side of the push plate 13 are fixedly connected to electric push rods 19. The output ends of both electric push rods 19 are fixedly connected to tapered plates 20. Both ends of the push plate 13 have through slots 30. Two connecting plates 14 are provided on the rear side of the push plate 13. Both ends of the front side of the two connecting plates 14 are fixedly connected to moving rods 29. The four moving rods 29 pass through the two through slots 30 and are slidably connected to them. The four moving rods 29 are fixedly connected to two horizontal plates 15. The two connecting plates... Both ends of the connecting plate 14 are formed with guide ramps 21. Two conical plates 20 correspond to the two guide ramps 21 respectively. When the two electric push rods 19 are activated, they drive the two conical plates 20 to move. The movement of the two conical plates 20 pushes the guide ramps 21 to move, which in turn drives the connecting plate 14 to move. Both ends of the push plate 13 are formed with support plates 22 on the upper and lower sides. Each of the four support plates 22 has a sliding rod 23 slidably connected inside. One end of each of the four sliding rods 23 is fixedly connected to both ends of the two connecting plates 14. Each of the four sliding rods 23 has a spring sleeve on its outer side. Springs 24, with their ends respectively attached to four support plates 22 and two connecting plates 14, provide support and limit the movement of the support plates 22 and connecting plates 14. A groove 34 is provided in the middle of the platform 8, and an L-shaped rod 26 is slidably connected inside the groove 34. A pusher plate 28 is fixedly connected to one side of the top of the L-shaped rod 26, and the pusher plate 28 is attached to the top of the supporting inclined plate 4. A rack 27 is fixedly connected to the bottom of the L-shaped rod 26. A gear 25 is fixedly connected to the middle of the rotating shaft 10, and the gear 25 meshes with the rack 27, causing the rotating shaft 10 to rotate. The drive mechanism rotates the gear 25, which in turn drives the rack 27 to move. Fixed plates 31 are fixedly connected to both sides of the top of the processing box 2. Lifting hydraulic rods 32 are fixedly connected to the top of each of the two fixed plates 31. The output ends of the two lifting hydraulic rods 32 pass through both sides of the fixed plates 31 and are slidably connected to the fixed plates 31. A limit plate 33 is provided on the top of the platform 8. The output ends of the two lifting hydraulic rods 32 are fixedly connected to both sides of the top of the limit plate 33, so that the lifting hydraulic rods 32 drive the limit plate 33 to press down, which facilitates pressing down and fixing the shellfish.

[0042] Specifically, first, clean water is poured into pool 1. Shellfish are then immersed and cleaned in pool 1, removing mud and sand and improving their cleanliness. Two lifting hydraulic rods 40 are activated, causing two lifting plates 48 to rise. These plates 48 then hoist two ropes 41, pulling two hanging lugs 39 upwards. As the lugs 39 rise, the filter plate 38 deflects inside the collection frame 37. During this upward deflection, the edge of the filter plate 38 slides along the inner side of the baffle 45, preventing the shellfish from falling. When the filter plate 38 moves to contact the baffle 45, the filter plate 38... When the filter plate 38 is tilted, the shellfish at the top of the filter plate 38 slide down to the bottom. When the filter plate 38 contacts the baffle 45, the hanging rope 41 continues to pull the hanging lug 39 to move the filter plate 38. The filter plate 38 drives the collection frame 37 to rise. After the filter plate 38 moves the shellfish to the water surface, the water mixed with impurities and mud slides down from the inside of the filter plate 38, thereby causing the collection frame 37 to rise to the top of the pool 1. When the collection frame 37 moves, it drives the top plate 43 to move. The top plate 43 drives the guide rod 44 to slide inside the guide plate 42 to guide and limit the collection frame 37, so that the collection frame 37 remains in a vertically rising state and improves the stability of the operation of the collection frame 37.

[0043] When the collection frame 37 and filter plate 38 move to the top of the pool 1, the shellfish on the top of the filter plate 38 slide down along the filter plate 38, causing the shellfish to slide to the top of the guide plate 6, and then slide along the guide plate 6 to the top of the bottom guide platform 3. Since the guide platform 3 has multiple drainage holes, water falls into the collection box 36 for collection. At the same time, the shellfish accumulated at the bottom fall to the top of the guide platform 3. At this time, the multiple lifting plates 5 are flush with the top of the multiple guide platforms 3, so the multiple shellfish fall to the top of the bottom lifting plate 5. The pusher hydraulic rod 17 is activated, causing the pusher hydraulic rod 17 to drive the support rod 7 to rise. When the support rod 7 rises, it drives the multiple lifting plates 5 to rise, so that the multiple lifting plates 5 are in multiple positions. As the multiple guide platforms 3 move, the multiple lifting plates 5 lift the shellfish that fall on top of the lifting plates 5 upwards, raising the shellfish to the side of the upper layer guide platform 3, so that the lifting plates 5 are level with the upper layer guide platform 3. Then the shellfish lifted on top of the lifting plates 5 fall to the top of the second layer guide platform 3. The above actions are repeated continuously, and the shellfish move upwards along the multiple lifting plates 5 and guide platforms 3. After the shellfish at the bottom layer are lifted, the shellfish piled on top of the guide plate 6 are automatically replenished under the action of gravity, so that the multiple lifting plates 5 push the shellfish to move upwards row by row on top of the lifting plates 5. Finally, they move along the support inclined plate 4 to the top of the platform 8, which facilitates the support and opening of the shellfish, and is conducive to automatic feeding of shellfish and easy operation.

[0044] Two lifting hydraulic rods 32 are activated, causing the limiting plate 33 to descend and move to the top of the supporting inclined plate 4. This activates the forward and reverse motors 18, which in turn rotate the shaft 10. The shaft 10 then rotates two rotating blocks 11, which in turn rotate two arc-shaped plates 12. These arc-shaped plates 12 rotate the push plate 13 to one side of the platform 8, bringing it into contact with multiple shellfish. The push plate 13 also brings the two connecting plates 14 and two horizontal plates 15 into contact with the shellfish, causing the two separating plates 16 to contact the recesses between the shellfish's shells. This activates two electric push rods 19, which in turn move the two conical plates 20 inwards, bringing them into contact with the two guide inclined plates 21. The conical plates 20 then push the two connecting plates 14 outwards, causing them to separate. This allows the two connecting plates 14 to move the two moving plates 15 together. The rod 29 and the two horizontal plates 15 separate vertically, causing the two horizontal plates 15 to drive the two separating plates 16 to separate. When the two separating plates 16 separate vertically, they separate the upper and lower shells of the shellfish for shell opening. During shell opening, the limiting plate 33 supports the shell, causing the forward and reverse motor 18 to start in reverse and drive the rotating shaft 10 to reverse. The rotating shaft 10 drives the push plate 13 to move in reverse for reset. At the same time, the rotating shaft 10 drives the gear 25 to rotate in reverse, thereby causing the gear 25 to drive the rack 27 to move. When the rack 27 moves, it drives the pusher plate 28 to move. The pusher plate 28 pushes the shellfish down from the top of the platform 8 for easy collection. This facilitates the rapid shell opening and collection of shellfish. A condenser 46 is fixedly connected to one side of the connecting frame 35. The input end of the condenser 46 is connected to the inside of the processing box 2, allowing cold air to be introduced into the processing box 2 and the inside of the cover plate 47 for cooling. Low-temperature treatment of the shellfish meat improves its taste.
