[0070] Example 2:

[0071] See also Figure 1-8 This embodiment provides a technical solution based on the first embodiment: the liquid stirring component 6 includes:

[0072] Two drive shafts 14, the two drive shafts 14 are rotatably connected to the two ends of the transmission box 3, one end of the drive shaft 14 is fixedly connected to the transmission bevel gear A15, and both ends of the transmission shaft 4 are fixedly connected to the transmission bevel gear B16, and the two transmission bevel gears B16 are respectively meshed with the two transmission bevel gears A15;

[0073] Two transmission screws 17 are rotatably connected to the two ends of the transmission box 3. One end of each transmission screw 17 is fixedly connected to a linkage sprocket 18. The two linkage sprockets 18 are connected by a chain. A drive motor 19 is fixedly connected to one side of the transmission box 3, and the output end of the drive motor 19 is fixedly connected to one of the transmission screws 17.

[0074] Two displacement frames 20, the two displacement frames 20 are respectively threadedly connected to the outside of the two transmission screws 17, the middle part of the displacement frame 20 is horizontally rotatably connected to the hollow shaft 21, and the hollow shaft 21 is also slidably connected to the outside of the drive shaft 14, the bottom end of the displacement frame 20 is vertically rotatably connected to the stirring shaft 22, the bottom end of the stirring shaft 22 is fixedly connected to the stirring roller 23, the top end of the stirring shaft 22 is fixedly connected to the reversing bevel gear A24, the outer side of the hollow shaft 21 is fixedly connected to the reversing bevel gear B25, and the reversing bevel gear A24 is meshed with the reversing bevel gear B25;

[0075] In this embodiment, a support bar is fixedly connected to the outer side of the driving shaft 14, and an assembly groove is opened on the inner wall of the hollow shaft 21, and the support bar is also slidably connected inside the assembly groove. Since the support bar is connected inside the assembly groove, when the displacement frame 20 linearly displaces, it can drive the hollow shaft 21 to synchronously displace on the driving shaft 14 under the limit of the support bar, and when the driving shaft 14 rotates, it can drive the hollow shaft 21 to rotate synchronously through the support bar.

[0076] In this embodiment, the bottom end of the displacement frame 20 is fixedly connected to a vertical pole with a hollow structure, and the bottom end of the vertical pole is fixedly connected to a protective cover. The liquid stirring roller 23 is located inside the protective cover, and multiple through holes are evenly provided on the outside of the protective cover. Through the provision of the protective cover, when the liquid stirring roller 23 rotates, it is possible to avoid damaging the aquatic products. In addition, multiple liquid stirring blades are fixedly connected to the outside of the liquid stirring roller 23, and the liquid stirring blades are of an arc-shaped structure. Multiple water flow holes are provided on the liquid stirring blades. Through the provision of the liquid stirring blades, the liquid in the concentration box 1 can be stirred over a wider range, thereby increasing the oxygen content of the liquid in the concentration box 1 to a greater extent.

[0077] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0078] Working principle: Water is poured into the collection box 1, and aquatic products are poured into the collection box 1 for collection. When the collection box 1 is transported, the transmission motor 5 and the air pump 46 can be started at irregular intervals. The start of the transmission motor 5 can drive the transmission shaft 4 to rotate, and the transmission bevel gear B16 drives the transmission bevel gear A15, prompting the drive shaft 14 to rotate synchronously. Since the hollow shaft 21 is connected to the drive shaft 14, when the drive shaft 14 rotates, it can drive the hollow shaft 21 to rotate accordingly, and the reversing bevel gear B25 drives the reversing bevel gear A24, and then the stirring roller 23 is driven by the stirring shaft 22 to stir the liquid in the collection box 1.

[0079] The operation of the air pump 46 can inject the external air flow into the air distribution pipe 48 through the air delivery pipe 49, and the air is finally injected into the liquid in the concentration tank 1 through the aeration pipe 50 through the diversion of the air distribution pipe 48, thereby cooperating with the stirring of the liquid stirring roller 23 to increase the oxygen content of the liquid in the concentration tank 1;

[0080] When the transmission shaft 4 rotates, it can shift the transmission spur gear 44 through the reduction spur gear 45, thereby driving the eccentric plate 38 to rotate continuously through the reduction shaft 37. In conjunction with the connection between the eccentric plate 38 and the guide groove 43, when the eccentric plate 38 rotates, it can push the guide plate 42 to swing back and forth under the support of the positioning shaft 40, prompting the knocking plate 41 to repeatedly knock the ringing plate, thereby dispersing the aquatic products and preventing the aquatic products from concentrating at the aeration area of ​​the stirring roller 23 and the aeration pipe 50, causing local hypoxia.

[0081] At the same time, the drive motor 19 can be started to drive the transmission screw 17 connected thereto to rotate, and the power of the drive motor 19 is transmitted through the chain setting, so that the two transmission screws 17 rotate synchronously. Under the connection between the transmission screw 17 and the displacement frame 20, the displacement frame 20 can be driven to move along the transmission screw 17, thereby adjusting the operating position of the liquid stirring roller 23;

[0082] The circulation pump 8 can be started to lead the liquid inside the central box 1 out through the external lead-in pipe 7, and return to the central box 1 through the filter box 26, the transmission pipe 10 and the return pipe 9. When the liquid flows inside the filter box 26, the liquid can be filtered with the help of the filter plate 28. When the filter plate 28 is not effective, the adjusting screw 33 is first rotated. Under the connection between the adjusting screw 33 and the displacement plate 34, the displacement plate 34 can be displaced along the adjusting screw 33. And because the push rod 35 is connected between the displacement plate 34 and the push plate 32, when the displacement plate 34 is displaced, the push plate 32 can be pulled with the help of the push rod 35, prompting the positioning frame 31 to rotate under the support of the positioning seat 29. When the filter box 26 is separated from the sealing plate 27, the sealing plate 27 can be unlocked, and then the sealing plate 27 is pulled up to pull the filter plate 28 out of the filter component 11 for replacement.
