[0038] The present utility model provides a shrimp body cleaning device, as Figures 1 to 3 shown, the shrimp body 50 cleaning device in this embodiment includes a conveying mechanism, a shrimp feeding mechanism, a shrimp cutting mechanism, and a cleaning mechanism. The conveying mechanism is used to transport the shrimp body 50, and the shrimp feeding mechanism, the shrimp cutting mechanism, and the cleaning mechanism are all located above the conveying mechanism and are arranged in sequence along the transportation direction of the conveying mechanism to respectively stabilize the shrimp body 50, cut the shrimp and clean the shrimp vein, and clean the shrimp brain. Hereinafter, the specific structures and connection relationships of the above-mentioned various parts of the shrimp body cleaning device according to the present utility model will be described in detail.

[0039] In this embodiment, as Figures 1 to 3As shown in the figure, the conveying mechanism includes a mounting base 10 formed in an inverted V-shaped structure, and the extending direction thereof is the transportation direction of the shrimp body 50. The conveying mechanism further includes a first conveying component and a second conveying component respectively arranged at two inclined surfaces of the mounting base 10. Specifically, both the first conveying component and the second conveying component are provided with a driving wheel 11, a driven wheel 12, and a conveyor belt 13 correspondingly sleeved on the outer sides of the driving wheel 11 and the driven wheel 12. The portions of the two conveyor belts 13 close to each other form the placing portion 17 of the conveying mechanism, so that the placing portion 17 is formed in an inverted V-shaped structure, thereby enabling the placing portion 17 to play a role in initially limiting the shrimp body 50, and further facilitating the subsequent processing of the shrimp body 50.

[0040] It should be noted that there are no specific restrictions on the specifications, installation positions, etc. of the driving wheel 11, the driven wheel 12, and the conveyor belt 13, and they should be determined comprehensively according to actual situations such as the specifications of the mounting base 10. As long as they can provide a continuous shrimp transportation channel to ensure the continuity of production. Similarly, there are no specific restrictions on the structure, shape, etc. of the mounting base 10. For example, an extending platform is formed at the bottom ends of the two inclined surfaces of the mounting base 10, and this extending platform can play a protective effect on the first conveying component and the second conveying component to increase the stability of the overall structure of the conveying mechanism.

[0041] In addition, the conveying mechanism further includes a first driving component, which is arranged in the open space of the mounting base 10. Specifically, it is provided with a driving gear 15 and a driven gear 16 that mesh with each other. The driving gear 15 and the driven gear 16 are respectively connected to the two driving wheels 11 correspondingly. The first driving component further includes a driving motor 14 connected to the driving gear 15 correspondingly, and the driving motor 14 is assembled at the mounting base 10. In this way, the driving motor transmits power to the driving gear 15, the driving gear 15 transmits power to the driven gear 16, and the two gears drive the two driving wheels 11 to rotate respectively, thereby realizing the transportation of the shrimp body 50. The connection methods of the above motor, gears, and conveying components all belong to the prior art, so they will not be elaborated here.

[0042] As Figures 1 to 3 shown, the cleaning device in this embodiment further includes a plate body 60, and the extending direction of the plate body 60 is the same as the transportation direction of the above-mentioned conveying mechanism. The above-mentioned shrimp feeding mechanism, shrimp cutting mechanism, and cleaning mechanism are all connected to the plate body 60 to facilitate the processing of the shrimp body 50.

[0043] The shrimp feeding mechanism is provided with a first swing arm assembly and a shrimp feeding roller 23 rotatably connected to the first swing arm assembly. The shrimp feeding roller 23 is formed with a limiting groove 231 adapted to the shrimp body 50. The first swing arm assembly can drive the shrimp feeding roller 23 to swing so that the limiting groove 231 abuts against the shrimp body 50. Specifically, the first swing arm assembly includes a shrimp feeding motor 20 and a shrimp feeding swing arm connected to each other, and the two are respectively arranged at both ends in the thickness direction of the plate body 60. The shrimp feeding swing arm is formed with an installation shell 21. The driving end of the shrimp feeding motor 20 passes through the plate body 60 through a through hole and is connected to the installation shell 21 so that the shrimp feeding motor 20 can drive the shrimp feeding swing arm to swing. More specifically, as Figure 1 shown, a first motor and a transmission part connected to the first motor are arranged inside the installation shell 21. The shrimp feeding roller 23 is connected to the power output end of the transmission part through a first rotating shaft 22 so that the first motor can drive the shrimp feeding roller 23 to rotate relative to the installation shell 21. It should be noted that the transmission part in this embodiment is formed in the form of a transmission wheel and a conveyor belt 13, but it is not limited thereto. The first motor can also drive the shrimp feeding roller 23 through forms such as a gear assembly.

[0044] The shrimp feeding roller 23 in this embodiment includes two circular rings and a plurality of teeth 231. The two circular rings are connected and fixed by a plurality of teeth 231 (that is, a plurality of teeth 231 are arranged between the two circular rings), and the plurality of teeth 231 are arranged at intervals along the circumferential direction of the circular ring. The shrimp feeding roller 23 is sleeved on the outer part of the first rotating shaft 22 through the central holes of the two circular rings. At this time, the plurality of teeth 231 are arranged around the outer part of the first rotating shaft 22. More specifically, each tooth 231 is formed with a V-shaped recess opening in a direction away from the first rotating shaft 22. The plurality of V-shaped recesses form the above-mentioned limiting groove 231 and the limiting groove 231 is located above the placement part 17. In this way, the limiting groove 231 and the placement part 17 can cooperate with each other to limit the shrimp body 50 from above and below the shrimp body 50 respectively to improve the stability of the shrimp body 50 during transportation.

[0045] It should be noted that the structure of the shrimp feeding roller 23 is not limited thereto. For example, the shrimp feeding roller 23 can also be provided with a sleeve sleeved on the outer part of the first rotating shaft 22, and the above two circular rings and the plurality of teeth 231 are both fixed to the sleeve to further improve the stability of the overall structure of the shrimp feeding roller 23.

[0046] It should be further noted that the above-mentioned shrimp feeding mechanism can adjust the distance between the shrimp feeding roller 23 and the placement part 17 through the shrimp feeding motor 20 to flexibly adapt to shrimp bodies 50 of different specifications. However, it is not limited to this. Although not shown in the figure, a spring can also be provided between the top of the installation shell 21 and the plate body 60, and the installation shell 21 is rotatably connected to the plate body 60 through components such as bearings. When the shrimp body 50 has not passed, the spring is in a stretched state; when the shrimp body 50 passes, the shrimp body 50 pushes up the installation shell 21 (at this time, the shrimp body 50 still abuts against the limit groove 231); after the shrimp body 50 passes, the installation shell 21 resets under the action of gravity.

[0047] Similarly to the above-mentioned shrimp feeding mechanism, the shrimp cutting mechanism is provided with a second swing arm assembly and a cutter 33 rotatably connected to the second swing arm assembly. The second swing arm assembly includes a shrimp cutting motor and a shrimp cutting swing arm 31 connected to each other. The shrimp cutting motor can drive the shrimp cutting swing arm 31 to swing, and the cutter 33 is rotatably connected to the shrimp cutting swing arm 31 through a second rotating shaft 32. The shrimp cutting motor of this embodiment includes a first shrimp cutting motor 301 and a second shrimp cutting motor 302 connected through a transmission member (such as a conveyor belt, etc.). The second shrimp cutting motor 302 passes through the plate body 60 and is connected to the shrimp cutting swing arm 31.

[0048] The cutter 33 in this embodiment is formed into a structure similar to a disc 230, and a cutting edge is formed around its outer part. When the shrimp body 50 moves forward, the rotating cutter 33 can correspondingly cut open the back or abdomen of the shrimp body 50 along the length direction of the shrimp body 50 (depending on the placement method of the shrimp body 50), so as to clean the shrimp vein. It should be noted that the specific structures included in the second swing arm assembly and the shrimp cutting swing arm 31 are similar to the above-mentioned shrimp feeding mechanism, so they will not be described in detail here as long as the above-mentioned technical effects can be achieved. In addition, the cutter 33 can adopt the cutter 33 for cleaning shrimp veins in the prior art.

[0049] Similarly to the above-mentioned shrimp feeding mechanism, the cleaning mechanism in this embodiment is provided with a third swing arm assembly and an adsorbing member 42 connected to the third swing arm assembly. The third swing arm assembly includes a cleaning motor 40 and a cleaning swing arm 41 connected to each other. The cleaning swing arm 41 is formed into a structure similar to an L shape, and the adsorbing member 42 is clamped at the end of the cleaning swing arm 41. The adsorbing member 42 is formed into a tubular structure, and its inlet end can be inserted into the head of the shrimp body 50, and its outlet end is connected to a vacuum pump to be able to suck out the shrimp brain.

[0050] It should be noted that there is no specific limitation on the distances among the shrimp feeding roller 23, the cutting knife 33, and the suction attachment 42. Preferably, when the shrimp body 50 has not completely escaped from the restriction of the shrimp feeding roller 23, the cutting knife 33 and the suction attachment 42 can process the shrimp body 50, so as to ensure the sufficiency and accuracy of cleaning. In addition, the following supporting members are omitted in the drawings of this embodiment. For example, the mounting base 10 can be fixed to the production site through support columns, which is a conventional technical means in this field and will not be elaborated here.

[0051] According to the shrimp body cleaning device of the present invention, the shrimp body 50 is placed at the placement part 17. The placement part 17 adapted to the shrimp body 50 can achieve the preliminary fixation of the shrimp body 50. During the process of the conveying mechanism transporting the shrimp body 50, the limiting groove 231 of the shrimp feeding mechanism abuts against the shrimp body 50 to further fix the shrimp body 50, so as to ensure the stable transmission of the shrimp body 50. During the stable advancement of the shrimp body 50, the shrimp line can be cleaned by the cutting knife 33, and the shrimp brain can be cleaned by the suction attachment 42. Thus, the shrimp line and the shrimp brain of the shrimp body 50 can be cleaned simultaneously by this device, effectively improving the cleaning efficiency of the shrimp body 50. In addition, the swing arm assembly can make this device adapt to different specifications of shrimp bodies 50, thereby effectively increasing the flexibility and application range of this device during use.

[0052] Finally, it should be noted that the above embodiments are only specific implementation manners of the present application, used to illustrate the technical solutions of the present application, rather than limiting them. The protection scope of the present application is not limited thereto. Although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that any person skilled in the art within the technical scope disclosed in the present application can still modify the technical solutions recorded in the foregoing embodiments, or can easily think of changes, or perform equivalent replacements on some of the technical features; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
