Technical Field
[0001] This utility model relates to the field of food processing technology, specifically a screening device for processing lobster tails. Background Technology
[0002] The lobster tail is a part of the lobster's body, usually referring to the pure meat after removing the head and shell. Lobster tails are widely popular for their delicious meat and unique texture, and hold an important place on seafood menus around the world.
[0003] Because lobster tails are easily perishable during processing, they need to be centrally frozen and packaged for transportation. Furthermore, the selling price of lobster tails varies depending on their size, necessitating sorting. However, existing sorting devices can only sort a limited number of tails at a time during multi-stage sorting, and the containers are not easy to clean after sorting. Therefore, we propose a sorting device for lobster tail processing. Utility Model Content
[0004] The purpose of this invention is to provide a screening device for processing lobster tails, so as to solve the problems mentioned in the background art.

The fixed sleeve is fixedly installed on one side of a fixed plate. An external threaded sleeve is fixedly installed on one side of each of the first, second, and third screening barrels. An internal threaded sleeve that is threadedly connected to the external threaded sleeve is fixedly installed on one side of the fixed plate. Screening holes are provided on each of the first, second, and third screening barrels, and the diameter of the screening holes on the first, second, and third screening barrels increases from small to large.
[0009] Furthermore, support columns are fixedly installed at the top and bottom of the interior of the fixed sleeve, the first screening bucket, and the second screening bucket. Ball bearings are rotatably connected to the bottom of the support columns.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1-5 This utility model provides a technical solution: a screening device for processing lobster tails, including a working plate 1, a support leg 2 fixedly installed at the bottom of the working plate 1, the top of the working plate 1 being inclined, a support mechanism 3 fixedly installed at the top of the working plate 1, a screening mechanism 4 for multi-stage screening of lobster tails of different sizes being provided at the top of the support mechanism 3, one end of the screening mechanism 4 being connected through a fixing plate 5, and a driving mechanism 6 for driving the screening mechanism 4 to rotate and screen being fixedly installed at the top of the working plate 1.
[0020] The inclined working plate 1 facilitates the downward movement of lobster tails inside the screening mechanism 4. The supporting mechanism 3 supports and positions the screening mechanism 4, making it easy to drive the screening mechanism 4 to rotate above the supporting mechanism 3 using the driving mechanism 6. This allows the screening mechanism 4 to screen lobster tails of different sizes, and allows lobster tails of different sizes to be collected from different positions. The screening mechanism 4 is also easy to disassemble and clean individually, preventing the lobster tails and impurities from causing bacterial growth.
[0021] Please see Figure 1 and Figure 2The support mechanism 3 includes a limiting ring 7, a mounting plate 8, a connecting shaft 9, and a support roller 10. Two sets of limiting rings 7 are fixedly installed on the outside of the screening mechanism 4. Two sets of mutually symmetrical mounting plates 8 are fixedly installed on the top of the working plate 1. A connecting shaft 9 is fixedly installed between the two sets of mounting plates 8. A support roller 10 that contacts the outside of the limiting ring 7 is provided on the outside of the connecting shaft 9. The drive mechanism 6 includes a gear ring 11, a drive motor 12, and a gear disk 13. A gear ring 11 is fixedly installed on the outside of the screening mechanism 4. A drive motor 12 is fixedly installed on the top of the working plate 1. The output end of the drive motor 12 is fixedly connected to a gear disk 13 that meshes with the gear ring 11.
[0022] When the screening mechanism 4 needs to be rotated for screening, the drive motor 12 drives the gear disk 13 to rotate, which in turn drives the gear ring 11 meshing with the gear disk 13 to rotate. This drives the limiting ring 7 on the screening mechanism 4 to rotate along the support roller 10, thus enabling the screening mechanism 4 to grade and screen the lobster tails inside.
[0023] Please see Figures 1-5 The screening mechanism 4 includes a fixed sleeve 14, a first screening barrel 15, a second screening barrel 16, a third screening barrel 17, a screening hole 18, an external threaded sleeve 19, and an internal threaded sleeve 20. The fixed sleeve 14 is fixedly installed on one side of the fixed plate 5. An external threaded sleeve 19 is fixedly installed on one side of each of the first screening barrel 15, the second screening barrel 16, and the third screening barrel 17. An internal threaded sleeve 20, which is threadedly connected to the external threaded sleeve 19, is fixedly installed on one side of the fixed plate 5. Screening holes 18 are provided on each of the first screening barrel 15, the second screening barrel 16, and the third screening barrel 17. The diameter of the screening holes 18 on the first screening barrel 15, the second screening barrel 16, and the third screening barrel 17 increases from small to large.
[0024] During the screening process, the lobster tails are placed inside the third screening bin 17. The screening holes 18 on the first screening bin 15, the second screening bin 16, and the third screening bin 17 have diameters that increase from small to large. This allows the lobster tails to be stored in order of size from smallest to largest inside the third screening bin 17, the second screening bin 16, the first screening bin 15, and the fixing sleeve 14. Furthermore, the first screening bin 15, the second screening bin 16, and the third screening bin 17 are provided with external threaded sleeves 19 on one side, which can be threadedly connected to internal threaded sleeves 20. This facilitates the disassembly and cleaning of the first screening bin 15, the second screening bin 16, and the third screening bin 17, preventing bacterial growth.
[0025] Please see Figure 1 and Figure 3The top and bottom of the fixed sleeve 14, the first screening barrel 15 and the second screening barrel 16 are all fixedly installed with support columns 21. The bottom of the support column 21 is rotatably connected with a ball bearing 22. The ball bearing 22 inside the fixed sleeve 14, the first screening barrel 15 and the second screening barrel 16 respectively contacts the outside of the first screening barrel 15, the second screening barrel 16 and the third screening barrel 17.
[0026] The support column 21 and ball bearing 22 are provided to support the first screening barrel 15, the second screening barrel 16 and the third screening barrel 17, and to prevent one side of the first screening barrel 15, the second screening barrel 16 and the third screening barrel 17 from shifting position during rotation screening.
[0027] Please see Figure 3 The lengths of the first screening bin 15, the second screening bin 16, and the third screening bin 17 increase sequentially. The different lengths of the first screening bin 15, the second screening bin 16, and the third screening bin 17 can change the dropping position of lobster tails of different sizes, so that lobster tails of different sizes can be collected separately.
[0028] In use, firstly, the inclined working plate 1 facilitates the downward movement of lobster tails inside the screening mechanism 4. The supporting mechanism 3 supports and positions the screening mechanism 4, making it easy to drive the screening mechanism 4 to rotate above the supporting mechanism 3 using the drive mechanism 6. This allows the screening mechanism 4 to screen lobster tails of different sizes, and allows lobster tails of different sizes to be collected from different positions. The screening mechanism 4 is easy to disassemble and clean, preventing bacterial growth caused by lobster tails and impurities remaining inside. When it is necessary to rotate the screening mechanism 4 for screening, the drive motor 12 drives the gear disk 13 to rotate, which in turn drives the gear ring 11 meshing with the gear disk 13 to rotate. This drives the limiting ring 7 on the screening mechanism 4 to rotate along the supporting roller 10, thus enabling the screening mechanism 4 to grade and screen the lobster tails inside. When screening, the lobster tails are placed inside the third screening bin 17, while the first screening bin 15 and the second screening bin 17 are placed inside the third screening bin 17. The screening holes 18 on the first and third screening bins 16 and 17 are arranged in ascending order of size, allowing the lobster tails to be stored sequentially from smallest to largest inside the third screening bin 17, the second screening bin 16, the first screening bin 15, and the fixing sleeve 14. The first, second, and third screening bins 15, 16, and 17 are each equipped with an external threaded sleeve 19 that can be threadedly connected to an internal threaded sleeve 20, facilitating disassembly and cleaning of these bins and preventing bacterial growth. The support column 21 and ball bearing 22 provide support for the first, second, and third screening bins 15, preventing positional shifts during rotational screening. The different lengths of the first, second, and third screening bins 15 and 16 allow for different dropping positions of the lobster tails, enabling separate collection of lobster tails of varying sizes.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
