It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0049] In the present disclosure, unless otherwise stated, directional words such as "inside and outside" refer to the inside and outside of a specific structural outline, and terms such as "first and second" are used only to distinguish one element from another and do not have order or importance.

[0050] like Figures 1 to 3 As shown, the present disclosure provides a fish mixture separation device, which is used to separate fish eggs from the fish mixture 10, and the separation device includes: a rotating mechanism 1, a first filter 2, a screening structure 3 and a second filter 4; the rotating mechanism 1 is used to accommodate the fish mixture 10 and rotate it; the first filter 2 is used to filter the fish mixture 10 after the rotating mechanism 1 rotates, so as to screen out the fish larger than 3 mm in the fish mixture; the screening structure 3 includes a screening container 31 and a screening plate 32, the screening container 31 is used to accommodate the fish mixture 10 after the first filter 2 is screened, and the screening plate 32 is movably arranged in the screening container 31 to screen the crustaceans in the fish mixture 10; the second filter 4 is used to filter the fish mixture 10 after the screening structure 3 is screened, so as to screen out the fish larger than 0.5 mm in the fish mixture 10.

[0051] It should be noted that among the catches obtained through specific plankton nets, except for fish eggs and copepods and ostracods among crustaceans, most of the remaining individuals are larger than 3 mm and are easy to screen; copepods and ostracods have various structures such as tentacles, bristles and spines, which are completely different from the smooth surface of the vast majority of floating fish eggs.

[0052] Based on this, the inventor of the present disclosure has designed the above-mentioned fish catch mixture separation device. In the above-mentioned technical scheme, firstly, the fish catch mixture is rotated by the rotating mechanism 1, so that the different fish catches in the fish catch mixture can be separated by centrifugal force, and the fish catches can be effectively prevented from piling up, thereby improving the screening efficiency; secondly, by setting the first filter 2, the fish catches larger than 3 mm in the fish catch mixture can be screened out, so that the fish catches in the fish catch mixture after passing through the first filter 2 are mainly fish eggs and crustaceans; then, the crustaceans are filtered through the screening plate 32 of the screening structure 3, and the fish eggs and a small number of other fish catches are retained; finally, the fish catches larger than 0.5 mm in the fish catch mixture 10 are screened out by the second filter 4, so that the fish catches in the fish catch mixture 10 after passing through the second filter 4 are only fish eggs. Thus, the effective screening of fish eggs is achieved, the screening efficiency is high, and the workload of the staff can be effectively reduced.

The screening tray body 322 is rotatably disposed in the screening container 31. The brush 323 is disposed on the outer peripheral surface of the screening tray body 322. The first driving unit is used to drive the screening tray body 322 to rotate so that the brush 323 adheres to the crustaceans in the fish catch mixture 10, thereby effectively screening the crustaceans in the screening tray 31, thereby facilitating the screening of fish eggs. However, the present disclosure does not limit the specific structure of the screening tray 32, and it is sufficient that the crustaceans can be effectively screened.

[0054] Reference Figure 1 and Figure 3 As shown, a plurality of brushes 323 are provided, and a plurality of brushes 323 are arranged in sequence on the outer peripheral surface of the screening plate body 322 in the circumferential direction thereof, and each brush 323 includes a brush rod 3231 and a plurality of bristles 3232, and the bristles 3232 are connected to the brush rod 3231, and the bristles 3232 form an acute angle with the brush rod 3231 and extend in a direction toward the brush rod 3231.

[0055] In this embodiment, during the rotation of the screening disc body 322, the bristles 3232 on the brush 323 form an acute angle with the brush rod 3231 and extend in the direction toward the brush rod 3231, that is, the bristles 3232 are in the shape of barbs, which can effectively adhere to the crustaceans in the fish mixture 10 and achieve a good screening effect.

[0056] Reference Figure 1 As shown, the separation device also includes a first collecting container 5 and a baffle 6. The baffle 6 is obliquely arranged at the opening of the first collecting container 5, and the baffle 6 is used to abut against the brush 323, so as to scrape the crustaceans adhered to the brush 323 into the first collecting container 5 during the rotation of the screening disc body 322, so that the crustaceans are separated from the screening disc 32 along the inclined baffle 6, thereby preventing the crustaceans from accumulating on the screening disc 32 and affecting the normal operation of the screening disc 32.

[0060] By configuring the first filter element 2 and the second filter element 4 as a filter screen structure, the manufacturing cost can be reduced while achieving a good screening effect; and by configuring the first filter screen at an end of the raised block 111 away from the inner surface of the funnel 11, a certain gap is left between the first filter screen and the funnel, which facilitates the fish mixture 10 to pass through the mesh of the first filter screen and then flow into the conveying pipe 12.

[0061] In addition, by providing the conveying pipeline 12 , the fish catch mixture 10 can be effectively conveyed, which facilitates the long-distance transmission of the fish catch mixture 10 .
