Description

Technical Field

[0001] This utility model relates to the field of aquatic product processing technology, and more specifically, to an aquatic product processing classification and screening device. Background Technology

[0002] Aquatic products are a general term for aquatic animal and plant products produced by marine and freshwater fisheries and their processed products, as well as related services or processing industries, such as aquatic product processing, aquatic product export trade, and ornamental aquatic products. Currently, in order to obtain higher economic value, people often need to grade aquatic products and classify them into corresponding grades according to their size before putting them on the market. In the process of aquatic product processing, sorting and screening devices are needed to screen aquatic products of different sizes.

[0003] However, existing screening devices are diverse. For example, utility model patent CN211134585U relates to a screening device for aquatic product processing. This utility model includes a first housing, with a dual-shaft motor fixedly connected to the bottom outer wall of the first housing. First rotating shafts are installed at the output ends of the dual-shaft motor on both sides. A first driving pulley is installed at the end of the first rotating shaft away from the dual-shaft motor. A first driven pulley is located above the first driving pulley. A second rotating shaft is bolted to the side of the first driven pulley near the first housing. An elliptical disc is installed at the end of the second rotating shaft away from the first driven pulley. This utility model, through various structural combinations, allows the device to replace manual labor with machinery, not only improving work efficiency but also reducing the mixing of aquatic products of different sizes during screening. This device can also clean the sieve plate, thereby reducing sieve plate clogging and improving work efficiency.

[0004] Although this screening device can replace manual labor, reduce clogging of the sieve plate, and improve work efficiency, it is difficult to classify and screen aquatic products according to their actual size during use. This is not conducive to ensuring the quality and consistency of aquatic products. At the same time, it is inconvenient to classify aquatic products such as fish and shrimp according to size, and cannot meet different market and processing needs. In order to avoid this phenomenon, it is necessary to design an aquatic product processing classification and screening device. Utility Model Content

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0027] like Figure 1 , Figure 2 as well as Figure 3 As shown, this is a structural schematic diagram of the aquatic product processing classification and screening device in this embodiment. The classification and screening device in this embodiment includes a screening pool 1. A first screen plate 2, a second screen plate 3, and a third screen plate 4 are fixedly connected in the screening pool 1. The first screen plate 2, the second screen plate 3, and the third screen plate 4 are fixedly connected to each other in pairs. Holes are opened on the first screen plate 2, the holes on the first screen plate 2 are the largest, the holes on the second screen plate 3 are medium in size, and the holes on the third screen plate 4 are the smallest. The first screen plate 2, the second screen plate 3, and the third screen plate 4 are fixed in pairs to form a whole screen plate and placed inside the screening pool 1. The holes on the first screen plate 2 can allow large fish and shrimp to pass through, the holes on the second screen plate 3 can allow medium-sized fish and shrimp to pass through, and the holes on the third screen plate 4 can allow small fish and shrimp to pass through.

[0028] In this embodiment, two positioning grooves 5 are provided on the top of the screening pool 1, and the two positioning grooves 5 are symmetrically distributed. A moving block 6 is slidably installed in one positioning groove 5, and a sliding block 7 is slidably installed in the other positioning groove 5. A connecting frame 8 is fixedly connected to both the moving block 6 and the sliding block 7. A screening frame 9 is fixed between the two connecting frames 8. A drive shaft 10 is installed in the screening frame 9 through a bearing. Multiple driving connecting plates 11 are provided on the surface of the drive shaft 10. During the classification and screening of aquatic products such as fish and shrimp, the screening frame 9 is first placed on the third screening plate 4, and water is injected into the screening pool 1 so that the water submerges most of the screening frame 9. Then, the mixed aquatic products are put into the screening frame 9. The aquatic products can swim freely in the frame. At this time, the multiple driving connecting plates 11 are driven by the rotating drive shaft 10. 1. The movable driving connecting plate 11 continuously taps the water surface within the frame, driving the aquatic products downstream and closer to the holes in the third sieve plate 4. Small fish and shrimp mixed in with the aquatic products can be driven through the holes into the lower classified storage space. Subsequently, the moving block 6 and the sliding block 7 can slide horizontally within the two positioning grooves 5. The moving block 6 and the sliding block 7 move the fixed screening frame 9 between them, causing the screening frame 9 to be moved horizontally onto the second sieve plate 3 and the first sieve plate 2 respectively, further screening medium-sized and large fish and shrimp according to size. This allows for classification and screening based on the actual size of the aquatic products, which helps ensure the quality and consistency of the aquatic products. At the same time, it facilitates the classification of fish, shrimp and other aquatic products according to size, meeting different market and processing needs.

[0029] It is worth noting that, such as Figure 6 As shown, in this embodiment, a protective cover plate 14 is provided on the top of the screening frame 9 via a hinge. Two metal blocking nets 23 are provided through the screening frame 9, and the two metal blocking nets 23 are symmetrically distributed on both sides of the screening frame 9. The metal blocking nets 23 are provided to block the aquatic products in the screening frame 9, so that the aquatic products can move together with the translation of the screening frame 9. The mesh structure can prevent water from blocking the moving screening frame 9.

[0030] like Figure 4As shown, in order to ensure the stable horizontal movement of the screening frame 9, in this embodiment, a screw 12 is installed inside one of the positioning grooves 5 via a bearing, and the screw 12 is threadedly connected to the moving block 6. A guide rod 13 is fixedly connected inside the other positioning groove 5, and the guide rod 13 is slidably installed between the guide rod 13 and the sliding block 7. A first pulley 15 is coaxially mounted on the surface of the screw 12. A drive motor 16 is mounted on one side of the screening tank 1 via a fixing frame. A second pulley 17 is sleeved on the output end of the drive motor 16 via a shaft, and the second pulley 17 is connected to the first pulley 15 via a shaft. The mounting housing 18 is detachably mounted on the fixed frame via belt drive, and the drive motor 16 is located inside the mounting housing 18. The drive motor 16 is controlled to drive the second pulley 17 to rotate through the output end of the drive motor 16. Through the belt drive, the first pulley 15 drives the screw 12 to rotate. At this time, with the guidance between the sliding block 7 and the guide rod 13, the rotating screw 12 can make the threaded moving block 6 move horizontally in the positioning groove 5. Thus, the moving block 6 and the sliding block 7 cooperate with the connecting frame 8 to stably move the screening frame 9 horizontally.

[0031] like Figure 3 As shown, in order to provide driving force for the movable driving connecting plate 11, an installation plate is fixedly connected inside the screening frame 9 in this embodiment. A waterproof cover 19 is provided on the installation plate. A rotary motor 20 is installed inside the waterproof cover 19, and the output end of the rotary motor 20 is fixedly connected to one end of the transmission shaft 10. The rotary motor 20 is placed inside the waterproof cover 19, which can provide waterproof protection for the rotary motor 20 and prevent water in the pool from splashing onto the motor. At the same time, by controlling the rotary motor 20, the output end of the rotary motor 20 drives the transmission shaft 10 to rotate, so as to ensure that the driving connecting plate 11 moves with the transmission shaft 10.

[0032] like Figure 1 As shown, in this embodiment, the inner wall of the screening pool 1 is fixedly connected with a supporting skirt 24. The first screen plate 2, the second screen plate 3 and the third screen plate 4 all abut against the supporting skirt 24. The interior of the screening pool 1 is fixedly connected with two symmetrical partition plates 25, and the partition plates 25 are fixed below the second screen plate 3. The partition plates 25 can divide the screening pool 1 into three areas. These three areas are located under the screen plates and can temporarily store the three types of aquatic products after classification. Supporting legs 26 are provided at the four corners of the bottom of the screening pool 1.

[0033] It is worth noting that, such as Figure 5As shown, in this embodiment, guide grooves 21 are provided on both inner walls of the screening pool 1. The surfaces of the first screen plate 2 and the third screen plate 4 that are far apart from each other are fixedly connected with matching slide bars 22. The matching slide bars 22 are slidably installed with the guide grooves 21. By utilizing the sliding cooperation between the guide grooves 21 and the matching slide bars 22, the whole screen plate composed of the first screen plate 2, the second screen plate 3 and the third screen plate 4 can be stably embedded into the screening pool 1, which facilitates the completion of subsequent screening operations.

[0034] 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.
