Description

Technical Field

[0001] This invention relates to the field of scallop processing technology, and more particularly to a scallop opening machine. Background Technology

[0002] Scallops, as a highly nutritious and economically valuable shellfish, primarily consume and process their adductor muscle, commonly known as "scallops." In the scallop processing industry chain, efficiently and cleanly extracting intact adductor muscles from scallops is a crucial step affecting production efficiency and product value.

[0003] Currently, the processing of scallops for adductor muscle removal is either done manually or by heating. To facilitate opening the shells, some processing plants first heat the scallops in batches (such as by steaming or blanching them in hot water), causing the adductor muscle to denature due to heat and weakening its connection with the shell, so that the shell opens slightly after being heated.

[0004] Existing batch heating methods (such as steaming in large pots) often suffer from uneven temperature and inaccurate time control, which can easily lead to some scallops being overcooked (resulting in shrinkage of the adductor muscle and a deterioration in taste) or not fully opening (increasing the difficulty of subsequent manual shell opening). To solve these problems, a shell opening machine is proposed. Summary of the Invention

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.

[0021] Please refer to Figures 1-7 The present invention provides a technical solution: a shell opening machine, including a box body 1, an upper conveying mechanism 2 and a lower conveying mechanism 3 are provided inside the box body 1, the upper conveying mechanism 2 is located above the lower conveying mechanism 3, the upper conveying mechanism 2 includes a perforated chain plate 23 rotatably arranged inside the box body 1, the lower conveying mechanism 3 includes a perforated chain plate 33 rotatably arranged inside the box body 1, a feeding area 8, an opening area 9 and a separation area 10 are formed between the perforated chain plate 23 and the perforated chain plate 33, a feeding hopper 5 is provided on one side of the box body 1, and a feeding mechanism 4 is provided through the top of the box body 1, the feeding mechanism 4 is located on the side of the perforated chain plate 23 away from the feeding hopper 5 and above the perforated chain plate 33, and the perforated chain plate 33 forms a feeding area 7 below the feeding mechanism 4.

[0022] Furthermore, such as Figure 4 As shown, the feeding area 8 is higher on the left and lower on the right, the separation area 10 is lower on the left and higher on the right, the opening area 9 is set horizontally and is flush with the bottom of the feeding area 8 and the separation area 10 respectively, and the loading area 7 is set horizontally and is flush with the higher end of the feeding area 8.

[0023] The upper conveying mechanism 2 includes a driven sprocket 21 and a driving sprocket 22 that pass through the housing 1 and are rotatably connected to the housing 1. A perforated chain plate 23 is sleeved on the driven sprocket 21 and the driving sprocket 22 and meshes with the driven sprocket 21 and the driving sprocket 22. The lower conveying mechanism 3 includes a driven sprocket 31 and a driving sprocket 32 ​​that pass through the housing 1 and are rotatably connected to the housing 1. A perforated chain plate 33 is sleeved on the driven sprocket 31 and the driving sprocket 32 ​​and meshes with the driven sprocket 31 and the driving sprocket 32.

[0024] Limiting bracket 1 24 and limiting bracket 2 34 are fixedly installed on the inner walls of both sides of the box 1. The perforated chain plate 1 23 is rotatably set in the limiting bracket 1 24, and the perforated chain plate 2 33 is rotatably set in the limiting bracket 2 34.

[0025] Furthermore, limit frame 1 24 is used to control the punching chain plate 1 23 to run along the specified track, and limit frame 2 34 is used to control the punching chain plate 2 33 to run along the specified track.

[0026] Both the first perforated chain plate 23 and the second perforated chain plate 33 are driven by the power mechanism 6. The power mechanism 6 includes a second gear 62 sleeved on the first drive sprocket 22 and a first gear 61 fixedly sleeved on the second drive sprocket 32. The first gear 61 and the second gear 62 are meshed and connected and are located on the outside of the housing 1. The power mechanism 6 also includes a motor 63 fixed on the outside of the housing 1. The output shaft of the motor 63 is connected to the end of the second drive sprocket 32 ​​through a coupling.

[0027] Multiple jet pipes 14 are linearly distributed and fixedly installed on one side of the housing 1. The multiple jet pipes 14 are all located below the perforated chain plate 33. Multiple exhaust holes are opened on the jet pipes 14, and the multiple jet pipes 14 are connected to the same air inlet pipe 15.

[0028] Furthermore, by injecting water into the chamber 1, first injecting clean water into the chamber 1 and making the water level cover the opening area 9, then injecting high-pressure steam into the air inlet pipe 15, and then expelling the high-pressure steam through multiple jet pipes 14 to heat the clean water in the chamber 1. The heated clean water can heat the water entering the chamber 1, causing it to open automatically. The overflow pipe 13 can control the height of the clean water level.

[0029] The feeding mechanism 4 includes a rectangular frame 41 that passes through the top of the box 1 and is fixedly connected to the box 1. A vertical plate 42 is fixedly installed on the inner wall of the rectangular frame 41 near the hopper 5. An inclined plate 43 is fixedly installed on the inner wall of the other side of the vertical plate 42. Two side plates 44 are provided below the rectangular frame 41. Both side plates 44 are fixedly connected to the vertical plate 42 and the inclined plate 43. Two symmetrically distributed swing plates 45 are rotatably installed between the vertical plate 42 and the inclined plate 43. The two swing plates 45 are arranged in a V-shape and rotate in opposite directions.

[0030] Two rotating shafts 46 are rotatably mounted on the top of the rectangular frame 41. Two swing plates 45 are fixedly connected to the corresponding rotating shafts 46. A swing arm 47 is fixedly mounted on the end of each rotating shaft 46 away from the hopper 5. An electric push rod 48 is fixedly mounted on the side of the rectangular frame 41 away from the hopper 5. An L-shaped plate 49 is fixedly mounted on the piston rod end of the electric push rod 48. A round shaft 410 is rotatably mounted through the L-shaped plate 49. The round shaft 410 passes through the two swing arms 47 and is rotatably connected to the two swing arms 47. A strip hole 471 is opened on the swing arm 47. The round shaft 410 passes through the two strip holes 471 and is rotatably connected to the inner wall of the two strip holes 471.

[0031] A horizontal plate 412 is slidably installed on the side of each of the two side plates 44 that are far apart from each other. A plurality of round rods 411 are rotatably installed between the two horizontal plates 412 in a linear distribution. The plurality of round rods 411 pass through the two side plates 44 and the two swing plates 45 and are slidably connected to the two side plates 44 and the two swing plates 45.

[0032] The swing plate 45 has multiple linearly distributed strip holes 451, and the side plate 44 has multiple linearly distributed strip holes 441. Multiple round rods 411 pass through the corresponding strip holes 441 and strip holes 451 respectively.

[0033] Furthermore, when the scallops are placed into the rectangular frame 41, the bottommost scallop will fall onto the perforated chain plate 33 below. At this time, these scallops are simultaneously in the feeding area 7 formed by the perforated chain plate 33 and the feeding mechanism 4. Then, the rotating perforated chain plate 33 will drive the scallops in the feeding area 7 to move towards the feeding area 8. Because of the high friction between scallops, when scallops are put into rectangular frame 41, except for the bottom scallop, the rest of the scallops will pile up and get stuck in rectangular frame 41. like Figures 6-7 As shown, by activating the electric actuator 48, the L-shaped plate 49 is driven to move up and down in a reciprocating manner. When the L-shaped plate 49 moves up, the electric actuator 48 and the two swing arms 47 work together to cause the left pivot 46 to drive the corresponding swing plate 45 to rotate counterclockwise, while the right pivot 46 drives the corresponding swing plate 45 to rotate clockwise. During this process, the bottom ends of the two swing plates 45 will move closer to each other and lift multiple round rods 411 to move up. At this time, the scallops piled between the vertical plate 42, the inclined plate 43 and the two swing plates 45 will be pushed up. Then, when the L-shaped plate 49 drives the circular shaft 410 to move down, the bottom ends of the two swing plates 45 will move away from each other, and the multiple circular rods 411 will move down. At this time, the scallops piled up between the vertical plate 42, the inclined plate 43 and the two swing plates 45 will spread out again due to the increased distance between the bottom ends of the two swing plates 45. The spread scallops then pass through the multiple circular rods 411 and fall down.

[0034] Furthermore, the spacing between two adjacent round rods 411, and the spacing between the vertical plate 42 and the inclined plate 43 and the adjacent round rods 411, are sufficient for a scallop to pass through at any angle. By moving the bottom ends of the two swing plates 45 closer to each other and further apart, the scallops stuck between the two swing plates 45 can be gathered, pushed upwards, and then spread out again, thus breaking up the scallops stuck on multiple round rods 411 and allowing them to pass through multiple round rods 411 and fall.

[0035] An overflow pipe 13 is fixedly installed through the side of the box body 1 away from the hopper 5. The bottom of the box body 1 is provided with two recesses 11, which are located below the feeding area 8 and the separation area 10, respectively. The side of the box body 1 is provided with two doors 12 that are adapted to the two recesses 11.

[0036] Furthermore, some debris produced when the scallops open will accumulate at the bottom of the two concave areas 11. This debris can be cleared by periodically opening the two hatches 12, and the water inside the tank 1 can also be drained.

[0037] In this embodiment: as follows Figures 3-5 As shown, during processing, first, clean water is injected into the box 1 and the water level is made to cover the opening area 9. Then, high-pressure steam is injected into the air inlet pipe 15. The high-pressure steam is discharged through multiple jet pipes 14 and heats the clean water in the box 1. Then, the motor 63 is started to drive the second drive sprocket 32 ​​to rotate clockwise. Under the transmission of gear 1 61 and gear 2 62, the first drive sprocket 22 rotates counterclockwise. Subsequently, the scallops are fed into the feeding mechanism 4. The scallops fed into the feeding mechanism 4 will fall orderly onto the feeding area 7. After being conveyed by the perforated chain plate 2 33, the scallops will move to the feeding area 8. The scallops that fall into the feeding area 8 will move towards the opening area 9 under the action of gravity. When the scallops move in the opening area 9, the water will heat them to open them. The two shells of the open scallops in the opening area 9 will abut against the perforated chain plate 1 23 and the perforated chain plate 2 33 respectively. Therefore, the open scallops in the opening area 9 will be conveyed from the lower opening area 9 to the higher separation area 10. After that, the open scallops will be conveyed from the separation area 10 to the discharge hopper 5 for discharge. Scallops that have been heated in the opening zone 9 but have not opened or have opened insufficiently are transferred from the opening zone 9 to the separation zone 10. Because they only come into contact with the perforated chain plate 23 below, the friction is limited. As a result, they slide down under the action of gravity and fall back into the opening zone 9 to continue heating until they are fully opened.

[0038] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
