Description

Technical Field

[0001] This invention relates to the field of aquatic product processing technology, specifically to a cleaning and draining device for shellfish aquatic products. Background Technology

[0002] Based on the natural surface structure characteristics of shells, their shells can be clearly divided into convex and concave surfaces: the convex surface, as the outer exposed surface, is in long-term contact with the external environment, and the types of impurities attached to the surface are more complex and the adhesion strength is higher, especially stubborn impurities, such as hardened mud and sand, biological adhering substances, etc., which are mostly concentrated in this area; the concave surface, as the inner surface that is in direct contact with the shell meat, is less affected by the external environment, and the amount and stubbornness of impurities attached are significantly lower than those on the convex surface.

[0003] In existing shell cleaning technologies, high-pressure water jet rinsing is the most widely used core solution. However, existing cleaning equipment generally lacks an active adjustment and precise control mechanism for the shell orientation. During the cleaning process, the shells are mostly in a free-scattered state, with their orientation completely random, causing some shells to remain in the cleaning area with their concave side facing upwards. At this time, the convex surfaces where impurities are concentrated and require focused cleaning are in a shielded position where the water flow cannot directly cover them. The impact force of the high-pressure water flow cannot effectively act on the impurities on the convex surfaces, resulting in incomplete cleaning. To ensure cleaning effectiveness, existing processes need to compensate for this deficiency by repeatedly mixing the shells, rearranging their orientation, and repeatedly performing high-pressure rinsing. However, repeated mechanical mixing causes violent collisions and friction between the shells and between the shells and the inner wall of the equipment, which can easily cause damage to the shell edges and shell fragmentation. This not only damages the integrity and appearance of the shells but also directly affects the quality stability of the subsequently processed finished products. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a cleaning and draining device for shellfish aquatic products, which aims to solve the problem that the current shellfish cleaning equipment cannot clean both the convex and concave surfaces of the shells in one go, resulting in the need for secondary cleaning. This can easily lead to violent collisions and friction between the shells and between the shells and the inner wall of the equipment, which can easily cause damage to the shell edges and breakage of the shells.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a washing and draining device for shellfish aquatic products, the washing and draining device for shellfish aquatic products comprising a shell, a transmission mechanism disposed within the shell, a washing mechanism, and an elastic pressing mechanism; The cleaning mechanism includes a first cleaning component and a second cleaning component respectively disposed on the upper and lower sides of the transmission mechanism; The transmission mechanism drives the shellfish to pass sequentially through the cleaning areas below the first cleaning component and above the second cleaning component. The elastic pressing mechanism is located on the side of the transmission mechanism where the first cleaning component is located, and is used to resist the impact of the second cleaning component on the shellfish.

[0006] According to one aspect of the above technical solution, the transmission mechanism includes a transmission component disposed within the outer shell and a transmission component for supporting shellfish aquatic products, wherein the transmission component drives the transmission component to rotate within the outer shell.

[0007] According to one aspect of the above technical solution, the transmission assembly includes at least two conveying rollers arranged front and rear, a first drive motor provided on at least one of the conveying rollers, and at least two conveying chains sleeved on the conveying rollers. Each of the conveying rollers has conveying gears at both ends, and the conveying chains are meshed with the conveying gears.

[0008] According to one aspect of the above technical solution, the transmission component includes a plurality of mesh wires disposed between the parallel conveyor chains, slide rails respectively disposed at both ends of the mesh wires, a slider movably connected to the slide rails, and a support rod fixedly connected to the sliders, wherein the slide rails are disposed on the conveyor chain tooth unit.

[0009] According to one aspect of the above technical solution, a movable roller is also provided at the end of the support rod away from the slider. An elastic element is provided between the movable roller and the slider. The elastic element is sleeved on the support rod. The movable roller is located inside a limiting plate on the outer shell. The movable roller moves along a preset moving path on the limiting plate.

[0010] According to one aspect of the above technical solution, the elastic pressing mechanism includes a support bracket disposed on the outer shell, an elastic pressing component movably connected to the support bracket, and a top-supporting component. The elastic pressing component and the support bracket are connected by a first electric push rod to adjust the height of the elastic pressing component. The transmission component drives the shellfish to lift the top-supporting component and inflates the pressing component to elastically press the shellfish.

[0011] According to one aspect of the above technical solution, the elastic pressing assembly includes at least two drive rollers, a drive belt sleeved on the drive rollers, and a pressing member sleeved on the drive belt. The drive rollers are driven to rotate by a second drive motor, and the drive belt drives the pressing member to rotate cyclically, pressing the shellfish between the pressing member and the mesh wire.

[0012] According to one aspect of the above technical solution, the clamping member has several isolation strips spaced along its length inside, the isolation strips dividing the inside of the clamping member into several clamping parts, and a squeezing air cushion is provided in the middle of any of the clamping parts. The squeezing air cushion has air storage chambers at both ends, and the height of the air storage chambers is greater than the height of the squeezing air cushion.

[0013] According to one aspect of the above technical solution, the top support assembly includes a second electric push rod fixed on the support bracket, a support plate movably connected to the second electric push rod, and a plurality of extrusion rollers disposed on the support plate. The extrusion rollers are disposed between the air storage chamber and the mesh, and the shellfish extrudes the extrusion rollers to press against the air storage chamber to inflate the extrusion air cushion.

[0014] According to one aspect of the above technical solution, the bottom of the outer shell is provided with a water guiding surface.

[0015] In summary, the shellfish cleaning and draining device proposed according to the present invention, by arranging a first cleaning component and a second cleaning component on the upper and lower sides of the mesh respectively, ensures that the convex and concave surfaces of the shellfish can be cleaned separately during a single transport of the shellfish. Simultaneously, when the shellfish are transported to a preset position, the air storage chamber is compressed to inflate the compression air cushion, which then presses the shells together to counteract the upward rinsing force of the second cleaning component, preventing violent collisions and friction between the shells and the inner wall of the device, thus avoiding edge damage and shell breakage. This invention can clean both the convex and concave surfaces of the shells in one process, eliminating the need for a second cleaning step. Furthermore, the elastic pressing function prevents edge damage, maintaining the integrity and appearance of the shells.

[0016] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0021] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. The term "and / or" as used herein includes any and all combinations of one or more of the related listed items.

[0022] Please see Figures 1-7 The diagram shows a structural schematic of a shellfish cleaning and draining device according to an embodiment of the present invention. The device includes a shell 1, a transmission mechanism, a cleaning mechanism, and an elastic pressing mechanism disposed within the shell 1. To improve the cleaning efficiency of shellfish, the cleaning mechanism includes a first cleaning component and a second cleaning component respectively located on the upper and lower sides of the transmission mechanism. The transmission mechanism carries the shellfish sequentially through cleaning areas below the first cleaning component and above the second cleaning component. While the shellfish are being transported on the transmission mechanism, the first cleaning component cleans the top of the shellfish. As the shellfish are transported above the second cleaning component, the second cleaning component applies high-pressure cleaning upwards. An elastic pressing mechanism presses the shellfish to counteract the impact force, thus completing the cleaning of both sides of the shellfish. It should be noted that in this embodiment, the shellfish are placed randomly, without specifying their orientation. Furthermore, to drain the cleaned water from the shell 1, an inclined water-guiding surface 34 is provided at the bottom of the shell 1 to guide and discharge the wastewater after high-pressure rinsing of the shellfish.

[0023] Furthermore, the first cleaning assembly includes a first rinsing tank 16, on which a water inlet pipe 17 is connected, and at the bottom of the first rinsing tank 16, a plurality of nozzles 19 are provided. Similarly, the second cleaning assembly includes a second rinsing tank 18, on which a water inlet pipe 17 and nozzles 19 of the same specification are also provided. The difference between the second and the first cleaning assembly is that the nozzles 19 on the second rinsing tank 18 face the same direction.

[0024] For transporting shellfish, the transmission mechanism includes a transmission component disposed within the outer shell 1 and a transmission component for supporting the shellfish. The transmission component drives the transmission component to rotate within the outer shell 1, so as to carry the shellfish sequentially through the cleaning areas below the first cleaning component and above the second cleaning component.

[0025] Furthermore, the transmission assembly includes at least two conveyor rollers 5 arranged front and rear, a first drive motor 4 mounted on at least one of the conveyor rollers 5, and at least two conveyor chains 2 sleeved on the conveyor rollers 5. Each conveyor roller 5 has conveyor gears at both ends, and the conveyor chains 2 mesh with the conveyor gears. Inside the outer casing 1, one conveyor roller 5 is located at each end, and each conveyor roller 5 has conveyor gears at both ends to mesh with the conveyor chains 2. The first drive motor 4 then drives the conveyor rollers 5 to rotate, thereby conveying the shellfish.

[0026] To support the shellfish and minimize obstruction, the conveying assembly includes several mesh wires 3 arranged between the parallel conveyor chains 2, slide rails 6 at both ends of the mesh wires 3, sliders 7 movably connected to the slide rails 6, and support rods 8 fixedly connected to the sliders 7. The slide rails 6 are provided with chain tooth units on the conveyor chains 2. The mesh wires 3 are chosen because they have a small diameter and a certain degree of flexibility. When passing through the cleaning area of ​​the second cleaning assembly, the mesh wires 3 are stretched, thereby minimizing their obstruction while ensuring support for the shellfish.

[0027] In order to connect the wire mesh 3 to the conveyor chains 2 at both ends, a slide rail 6 is fixed on each tooth unit of the conveyor chain 2, and a slider 7 is movably connected to the slide rail 6. The two ends of the wire mesh 3 are respectively sleeved on the corresponding parallel tooth units. The tension of the wire mesh 3 is adjusted by the slider 7 moving laterally in the slide rail 6.

[0028] In addition, a guide plate 15 is provided on the outer shell 1, and a preset path for the slider 7 to move is opened on the guide plate 15. The moving path is composed of a first straight groove 11, an inclined groove 13, and a second straight groove 14. The connection between the first straight groove 11 and the second straight groove 14 and the guide plate 15 is provided with an inclined transition. The end of the support rod 8 away from the slider passes through the moving path.

[0029] It should be noted that a limiting block 35 is also provided at the end of the support rod 8 away from the slider 7. Similarly, a moving roller 9 is also provided at the end of the support rod 8 away from the slider 7. The moving roller 9 has a groove 36 inside, and the limiting block 35 can move up and down within the groove 36. An elastic element 10 is provided between the moving roller 9 and the slider 7, and the elastic element 10 is sleeved on the support rod 8. The moving roller 9 can rotate relative to the support rod 8, thereby reducing the friction of the support rod 8 in the moving path. When the moving roller 9 moves in the second straight groove 14, the mesh 3 is in a contracted state. At this time, the mesh 3 drives the shellfish forward. When it moves to the inclined groove 13, it drives the slider 7 to move along the slide rail 6. At this time, the mesh 3 begins to open. It then moves to the top of the second cleaning component and enters the cleaning area, thus greatly reducing the obstruction of the shellfish and improving the cleaning efficiency of the shellfish.

[0030] To counteract the impact force on the shellfish, the elastic compression assembly includes a support bracket 20 mounted on the outer shell 1, an elastic compression component movably connected to the support bracket 20, and a top support component. The elastic compression assembly is integrally mounted on a mounting shell 22. The mounting shell 22 and the support bracket 20 are connected by a first electric push rod 21 to adjust the height of the elastic compression assembly. A transmission component drives the shellfish to lift the top support component and inflates the compression assembly to elastically compress the shellfish.

[0031] Specifically, the elastic clamping assembly includes at least two drive rollers 23, a drive belt 24 sleeved on the drive rollers 23, and a clamping member sleeved on the drive belt 24. The drive rollers 23 are driven to rotate by a second drive motor 30, and the drive belt 24 drives the clamping member to rotate cyclically, clamping the shellfish between the clamping member and the mesh 3. The clamping member has several isolation strips 26 spaced along its length inside, dividing the interior into several clamping sections. Each clamping section has a compression air cushion 25 in the middle, which, together with the elastic pull rope 29, forms a compression chamber 28. Each end of the compression air cushion 25 has an air storage chamber 27, the height of which is greater than the height of the compression air cushion 25, so that the clamping member has a concave shape.

[0032] The top-support assembly includes a second electric actuator 31 fixed to the support bracket 20, a support plate 32 movably connected to the second electric actuator 31, and a plurality of extrusion rollers 33 disposed on the support plate 32. The extrusion rollers 33 are disposed between the air storage chamber 27 and the mesh 3. The shellfish squeezes the extrusion rollers 33 to press against the air storage chamber 27 and inflate the extrusion chamber 28. It should be noted that above the inclined groove 13, the upper extrusion rollers 33 are removed. When moving to the deformation area of ​​the mesh 3, the extrusion air cushion 25 can contract in the middle due to the absence of extrusion rollers 33, reducing the extrusion force. This avoids the wavy structure at the edge of the shell getting stuck with the mesh 3, making it difficult for the mesh 3 to deform and move. The second electric actuator 31 can also adjust the height of the extrusion rollers 33 to adjust to a suitable height, making it easier for the shellfish to deform the extrusion rollers 33.

[0033] In summary, the shellfish cleaning and draining device proposed according to the present invention, by arranging a first cleaning component and a second cleaning component on the upper and lower sides of the mesh respectively, ensures that the convex and concave surfaces of the shellfish can be cleaned separately during a single transport of the shellfish. Simultaneously, when the shellfish are transported to a preset position, the air storage chamber is compressed to inflate the compression air cushion, which then presses the shells together to counteract the upward rinsing force of the second cleaning component, preventing violent collisions and friction between the shells and the inner wall of the device, thus avoiding edge damage and shell breakage. This invention can clean both the convex and concave surfaces of the shells in one process, eliminating the need for a second cleaning step. Furthermore, the elastic pressing function prevents edge damage, maintaining the integrity and appearance of the shells.
