Description

Technical Field

[0001] The utility model relates to the field of lobsters, in particular to a lobster sorting device with a cleaning function. Background Art

[0002] Lobsters are not only delicious but also rich in nutrients, including protein, fat, zinc, iodine, selenium, amino acids, vitamins and other nutrients. Appropriate consumption can provide the nutrients required by the human body and is beneficial to physical health. When processing lobsters, a sorting device is needed to sort lobsters of different sizes to meet different market demands.

[0003] The existing lobster sorting device cannot clean the sieve plate, which easily causes lobster debris to remain on the sieve plate, resulting in poor screening effect. Moreover, it cannot be cleaned simultaneously during sorting, so further cleaning is required after sorting, which easily leads to low lobster processing efficiency.

[0004] Therefore, in view of the problems of the existing lobster sorting device that cannot clean the sieve plate and cannot be cleaned simultaneously during sorting, a lobster sorting device with a cleaning function is developed. By means of the movable installation method inside the screening component, the screening effect is improved. At the same time, through the transmission structure arranged inside the cleaning tank, the sorted lobsters can be cleaned, thus improving the lobster processing efficiency. Summary of the Utility Model

[0005] In order to overcome the problems of the existing lobster sorting device that cannot clean the sieve plate and cannot be cleaned simultaneously during sorting.

[0006] The technical solution of the utility model is: a lobster sorting device with a cleaning function, including a housing, and also including a cleaning tank and a screening component. The cleaning tank and the screening component are both arranged inside the housing, and the screening component is located on the right side of the cleaning tank. The inside of the cleaning tank is respectively rotatably connected with a first rolling roller and a second rolling roller, and the second rolling roller is located below the first rolling roller. The left side of the first rolling roller is connected to the output end of the motor. A driving wheel is arranged on the outer surface of the first rolling roller. A driven wheel is arranged on the outer wall of the second rolling roller. The driving wheel is connected to the driven wheel through a belt. Brushes are distributed on both the first rolling roller and the second rolling roller.

[0007] Preferably, the setting of the screening component can sort lobsters of different sizes. At the same time, through the installation structure arranged inside it, it is convenient to disassemble and clean the first screening plate, the second screening plate and the third screening plate, so as to avoid the impurities remaining on the surfaces of the first screening plate, the second screening plate and the third screening plate after lobster sorting, thereby improving the screening effect. There are three cleaning tanks in total, and they correspond to the left edges of the first screening plate, the second screening plate and the third screening plate one by one. Through the setting of the cleaning tanks, the sorted lobsters can be carried, so that the lobsters can wait to be cleaned in the cleaning tanks. The motor provides a power source for the rotation of the first rolling roller and the second rolling roller. The setting of the motor can effectively and accurately control the rotation speed and direction of the first rolling roller. By starting the motor, the first rolling roller rotates, and the driving wheel located on the first rolling roller rotates synchronously, driving the driven wheel connected to the driving wheel by a belt to rotate synchronously, prompting the second rolling roller to rotate simultaneously. This transmission method has the advantages of simple structure, stable transmission and high efficiency. The second rolling roller is located diagonally below the first rolling roller, so that when the first rolling roller and the second rolling roller roll, the lobsters in the cleaning tank can be comprehensively cleaned and brushed by the brush, and at the same time, the piled-up lobsters are continuously driven to roll, making full contact with the water flow and the brush, ensuring that the lobsters can be evenly cleaned, thereby improving the efficiency of lobster processing and enhancing the cleaning effect.

[0008] Preferably, water discharge grooves are provided on the lower surfaces of the cleaning tanks and the housing. A water collection tank is installed at the bottom of the housing. Through the setting of the water discharge grooves, the water flows in the three cleaning tanks are discharged through the water discharge grooves and finally flow into the water collection tank for storage, so as to facilitate the secondary utilization of water resources and has the effect of saving water resources.

[0009] Preferably, a feed inlet and a water inlet pipe are provided on the top of the housing, and the feed inlet is located on the right side of the water inlet pipe. One end of the water inlet pipe close to the housing passes through the top of the housing and is connected to a water distribution pipe. Five cylindrical spray nozzles are provided on the lower surface of the water distribution pipe. The setting of the feed inlet facilitates personnel to directly pour lobsters from the top of the housing onto the first screening plate for screening work. The setting of the water inlet pipe provides a water flow source for cleaning the lobsters in the cleaning tank. The water flow enters the water distribution pipe through the water inlet pipe and flushes the cleaning tank located below it through the spray nozzles. The setting of the water distribution pipe and the five spray nozzles enables the water flow to be sprayed more efficiently and evenly contact the lobsters.

[0010] Preferably, the screening assembly includes a first screening plate, a second screening plate, a third screening plate, a sliding sleeve, a connecting rod, a first mounting member, and a second mounting member. The sliding sleeve is connected to the right sides of the first screening plate, the second screening plate, and the third screening plate respectively by bolts. The first mounting member is fixedly connected to the lower surfaces of the first screening plate and the second screening plate, and the second mounting member is fixedly connected to the upper surfaces of the second screening plate and the third screening plate. The first screening plate, the second screening plate, and the third screening plate are detachably installed with the sliding sleeve by bolts, so that they can be separated from the sliding sleeve and thus disconnected from the housing, facilitating disassembly by personnel. The provision of the first mounting member and the second mounting member not only provides connection support between the first screening plate, the second screening plate, and the third screening plate, but also enables detachable installation, facilitating cleaning by personnel after disassembly.

[0011] Preferably, the inner side of the second mounting member is connected to the right end of the connecting rod by a rotating shaft. The left end of the connecting rod is provided with a T-shaped head. The two ends of the T-shaped head respectively pass through the round holes on both sides of the first mounting member, and the outer wall of the T-shaped head is provided with an external thread adapted to the internal thread of the nut. The provision of the rotating shaft enables the connecting rod to move flexibly. The connecting rod provides connection support for the first screening plate, the second screening plate, and the third screening plate to be placed obliquely. The provision of the T-shaped head can provide a more stable and efficient connection, increasing the overall connection stability of the connecting rod and facilitating the installation of the connecting rod to the first mounting member. When disassembly and cleaning are required, by screwing the nut off the T-shaped head and then sliding the right end of the connecting rod back and forth on the rotating shaft, the T-shaped head can be successively removed from the round holes on both sides of the first mounting member, and then by the rotational connection of the rotating shaft, the connecting rod can be laid flat. Through this movable installation method, it is convenient for personnel to effectively disassemble and clean the first screening plate, the second screening plate, and the third screening plate, preventing residues after sorting from adhering to their surfaces, so that the screening effect will not be affected during the next screening.

[0012] Preferably, an installation groove is formed on the right side inside the housing, and a sliding rod is fixedly connected in the installation groove. Springs are provided at both the upper and lower ends of the outer wall of the sliding rod. The installation of the installation groove provides space for the installation of the sliding rod, enabling the sliding sleeve to move up and down on the sliding rod. There are three installation grooves in total, corresponding one by one to the sliding sleeves on the first screening plate, the second screening plate, and the third screening plate, enabling the three sliding sleeves to perform limited lifting and lowering movements respectively in the corresponding installation grooves to generate vibrations for sorting lobsters of different sizes. The provision of the springs buffers the impact force generated when the sliding sleeve moves up and down on the sliding rod, avoiding wear and damage of the sliding sleeve caused by large-amplitude and long-time vibrations and extending the service life of the device.

[0013] Preferably, the bottom of the third sieve plate is in contact with the top of the cylinder. The bottom of the housing is provided with support columns, and the lower surface of the support columns is sleeved with anti-slip pads made of rubber. The setting of the cylinder provides a power source for the overall vibration of the sieve assembly. When the cylinder is started, through the continuous telescopic movement of the cylinder, it contacts the bottom of the third sieve plate, so that the sliding sleeves on the third sieve plate synchronously move up and down on the sliding rods. Through the combined use of the connecting rod, the first mounting member and the second mounting member, the acting force output by the cylinder can be transmitted, so as to drive the sliding sleeves on the first sieve plate and the second sieve plate to synchronously move up and down back and forth, so that the lobsters can be sorted through vibration. The setting of the support columns provides stable support for the housing. The anti-slip pads made of rubber have the advantages of strong wear resistance and strong anti-slip performance, avoiding the position deviation of the parts inside the housing during work and providing the stability of support.

This transmission method has the advantages of simple structure, stable transmission and high efficiency. The second rolling roller 4 is located obliquely below the first rolling roller 3, so that when the first rolling roller 3 and the second rolling roller 4 roll, the lobsters inside the cleaning tank 2 can be comprehensively cleaned and brushed by the brushes 8. At the same time, the stacked lobsters are driven to continuously roll, making full contact with the water flow and the brushes 8, ensuring that the lobsters can be evenly cleaned, thereby improving the efficiency of lobster processing and enhancing the cleaning effect. Water discharge grooves 10 are opened on the lower surfaces of both the cleaning tank 2 and the housing 1. A water collection tank 11 is installed at the bottom of the housing 1. Through the setting of the water discharge grooves 10, the water flows in the three cleaning tanks 2 are discharged through the water discharge grooves 10 and finally flow into the water collection tank 11 for storage, so as to facilitate the secondary utilization of water resources, having the effect of saving water resources. An inlet and a water inlet pipe are respectively arranged at the top of the housing 1, and the inlet is located on the right side of the water inlet pipe. One end of the water inlet pipe close to the housing 1 passes through the top of the housing 1 and is connected to a water distribution pipe 12. Five cylindrical spray heads 13 are arranged on the lower surface of the water distribution pipe 12. The setting of the inlet is convenient for personnel to directly pour lobsters from the top of the housing 1 onto the first screening plate 14 for screening work.

The first screening plate 14, the second screening plate 15, the third screening plate 16 and the sliding sleeve 17 are installed by bolts, so that they can be separated from the sliding sleeve 17, and thus separated from the connection with the housing 1, facilitating disassembly by personnel. The settings of the first mounting member 19 and the second mounting member 20 not only provide connection support between the first screening plate 14, the second screening plate 15 and the third screening plate 16, but also enable detachable installation, so as to facilitate cleaning after disassembly by personnel. The inner side of the second mounting member 20 is connected to the right end of the connecting rod 18 through a rotating shaft. The left end of the connecting rod 18 is provided with a T-shaped head 21. The two ends of the T-shaped head 21 respectively pass through the round holes on both sides of the first mounting member 19, and the outer wall of the T-shaped head 21 is provided with an external thread adapted to the internal thread of the nut. The rotating shaft enables the connecting rod 18 to move flexibly. The connecting rod 18 provides connection support for the first screening plate 14, the second screening plate 15 and the third screening plate 16 to be inclined. The T-shaped head 21 can provide a more stable and efficient connection, increasing the overall connection stability of the connecting rod 18 and facilitating the installation of the connecting rod 18 and the first mounting member 19. When disassembly and cleaning are required, by screwing the nut off the T-shaped head 21, and then sliding the right end of the connecting rod 18 back and forth on the rotating shaft, the T-shaped head 21 can be sequentially removed from the round holes on both sides of the first mounting member 19, and then through the rotational connection of the rotating shaft, the connecting rod 18 can be laid flat. Through this movable installation method, it is convenient for personnel to effectively disassemble and clean the first screening plate 14, the second screening plate 15 and the third screening plate 16, preventing residues after sorting from adhering to their surfaces, so that the screening effect will not be affected during the next screening.

[0029] Please refer to Figures 6 - 7, in this embodiment, an installation groove 22 is formed on the right side inside the housing 1, and a slide rod 23 is fixedly connected in the installation groove 22. Springs 24 are arranged at both the upper and lower ends of the outer wall of the slide rod 23. The slide sleeve 17 is slidably connected to the outer surface of the slide rod 23. The provision of the installation groove 22 provides space for the installation of the slide rod 23, enabling the slide sleeve 17 to move up and down on the slide rod 23. A total of three installation grooves 22 are provided, corresponding one-to-one with the slide sleeves 17 on the first sieve plate 14, the second sieve plate 15, and the third sieve plate 16, so that the three slide sleeves 17 can perform limited lifting and lowering movements respectively in the corresponding installation grooves 22, thereby generating vibrations to facilitate the sorting of lobsters of different sizes. The provision of the springs 24 buffers the impact force generated when the slide sleeve 17 moves up and down on the slide rod 23, avoiding the wear and damage of the slide sleeve 17 caused by large-amplitude and long-time vibrations, and extending the service life of the device. The bottom of the third sieve plate 16 is in contact with the top of the cylinder 25. Support columns are installed at the bottom of the housing 1, and an anti-slip pad made of rubber is sleeved on the lower surface of the support columns. The provision of the cylinder 25 provides a power source for the vibration of the entire sieve component. When the cylinder 25 is started, through the continuous telescopic movement of the cylinder 25, it contacts the bottom of the third sieve plate 16, causing the slide sleeve 17 on the third sieve plate 16 to move up and down back and forth synchronously on the slide rod 23. Through the combined use of the connecting rod 18, the first mounting member 19, and the second mounting member 20, the acting force output by the cylinder 25 can be transmitted, thereby driving the slide sleeves 17 on the first sieve plate 14 and the second sieve plate 15 to move up and down back and forth synchronously on the corresponding slide rods 23, so that the lobsters can be sorted through vibrations. The provision of the support columns provides stable support for the housing 1. The anti-slip pad made of rubber has the advantages of strong wear resistance and strong anti-slip property, avoiding the displacement of the parts inside the housing 1 during operation and providing the stability of the support.

[0030] During operation, first, the lobsters are directly poured from the top of the housing 1 onto the first sieve plate 14 through the feed inlet. At the same time, the cylinder 25 is started. Through the continuous telescopic movement of the cylinder 25, it contacts the bottom of the third sieve plate 16, causing the slide sleeve 17 on the third sieve plate 16 to move up and down back and forth synchronously on the slide rod 23. Through the combined use of the connecting rod 18, the first mounting member 19, and the second mounting member 20, the acting force output by the cylinder 25 can be transmitted, thereby driving the slide sleeves 17 on the first sieve plate 14 and the second sieve plate 15 to move up and down back and forth synchronously on the corresponding slide rods 23, enabling the lobsters of different sizes on the first sieve plate 14 to reach their respective appropriate first sieve plates 14, second sieve plates, and third sieve plates 16 respectively through the sorting openings of different sizes provided on the first sieve plate 14 and the second sieve plate 15;

[0031] Then, the lobsters flow into the corresponding cleaning tanks 2 through the first sieve plate 14, the second sieve plate, and the third sieve plate 16 which are placed by vibrating and tilting. Then, the water spray heads 13 are used to spray water. By starting the motor 7, the first rolling roller 3 rotates, and the driving wheel 5 located on the first rolling roller 3 rotates synchronously, driving the driven wheel 6 connected to the driving wheel 5 through the belt 9 to rotate synchronously, prompting the second rolling roller 4 to rotate simultaneously. When the first rolling roller 3 and the second rolling roller 4 are rolling, the lobsters in the cleaning tank 2 can be comprehensively cleaned and brushed by the brush 8. At the same time, the piled-up lobsters are continuously driven to roll, making full contact with the water flow and the brush 8 to ensure that the lobsters can be evenly cleaned;

[0032] Finally, through the setting of the water outlet trough 10, the water flow in the three cleaning tanks 2 is discharged through the water outlet trough 10 and finally flows into the water collection tank 11 for storage, so as to facilitate the secondary utilization of water resources, having the effect of saving water resources.

[0033] Through the above steps, through the movable installation method inside the screening assembly, it is convenient for personnel to effectively disassemble and clean the first sieve plate 14, the second sieve plate 15, and the third sieve plate 16, preventing the residues after sorting from adhering to their surfaces. Thus, when the next screening is carried out, the screening effect will not be affected. At the same time, through the transmission structure arranged inside the cleaning tank 2, the sorted lobsters can be cleaned, thereby improving the efficiency of lobster processing.

[0034] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those skilled in the art, various changes can be made without departing from the purpose of the present invention.
