Description

Technical Field

[0001] The utility model relates to the technical field of shrimp seed screening devices, in particular to a shrimp seed screening device. Background Art

[0002] During the shrimp fry breeding process, the shrimp fry needs to be screened and then the smaller shrimp fry are classified into larger ones. The larger shrimp fry are then moved to the breeding pond for further breeding, and the smaller shrimp fry are placed in the breeding frame and raised to the appropriate size before being transferred. This process requires the use of a shrimp fry screening device for auxiliary screening.

[0003] In actual work, the function and structure of the shrimp seed screening device in the prior art are relatively perfect, which can basically meet the daily shrimp seed screening needs, but there are still the following two problems:

[0004] 1. Shrimp fry are usually screened through a sieve. When the shrimp fry falls from the sieve holes of the sieve, the height is too high and the shrimp fry falls directly to the bottom, which can easily cause the shrimp fry to be injured and the shrimp claws to be broken, thereby reducing the value of the shrimp fry;

[0005] 2. When using the screen, the shrimp fry generally will not cooperate and fall through the screen holes. At this time, they need to be driven away manually using a brush. The brush driving method will cause the shrimp fry's claws to be injured or broken, thus affecting the value of the shrimp fry.

[0006] Therefore, the utility model provides a shrimp seed screening device. Utility Model Content

[0028] Further, such as Figure 4As shown: the second screening structure 3 includes a rectangular frame 31, one side of the outer surface of the rectangular frame 31 is fixedly connected to one side of the outer surface of the screening frame 1, one side of the outer surface of the rectangular frame 31 is fixedly installed with a first motor 32, the output end of the first motor 32 is fixedly connected with a first screw 33, the end of the first screw 33 away from the first motor 32 is rotatably connected to the inner wall of the rectangular frame 31, the outer surface of the first screw 33 is threadedly connected with a screw hole block 34, the outer surface of the screw hole block 34 is slidably connected to the inner wall of the rectangular frame 31, one side of the outer surface of the screw hole block 34 is fixedly connected with a connecting rod 35, the end of the connecting rod 35 away from the screw hole block 34 is fixedly connected with a mounting plate 36, the top of the outer surface of the mounting plate 36 is fixedly installed with a second motor 37, and the output end of the second motor 37 is fixedly connected with a second screw 3 8. The outer surface of the second screw 38 is threadedly connected with a threaded barrel 39, and the bottom of the outer surface of the threaded barrel 39 is fixedly connected with an auxiliary plate 311. The top of the outer surface of the auxiliary plate 311 is fixedly connected with a limiting round rod 310, and the limiting round rod 310 is slidably set on the inner wall of the mounting plate 36. The bottom of the outer surface of the auxiliary plate 311 is fixedly connected with a screening push plate 312, and the inner wall of the screening push plate 312 is provided with a screening hole groove.

[0033] When in use: the rectangular ring block 23 on the screening plate 21 is inserted into the inner wall of the rectangular ring frame 25, and the shrimp fry is placed on the screening plate 21. At this time, the shrimp fry can slide down from the inner wall of the first screening rectangular hole 22, and then fall to the bottom of the screening frame 1 under the action of the guide plate 24;

[0034] At this time, the second motor 37 is started, so that the second motor 37 can drive the second screw 38 to rotate, and then drive the threaded barrel 39 to move, so that the threaded barrel 39 can drive the auxiliary plate 311 to move, so that the auxiliary plate 311 can drive the screening push plate 312 to move, so that the screening push plate 312 is in contact with the screening plate 21;

[0035] At this time, the first motor 32 is started, so that the first motor 32 can drive the first screw 33 to rotate, and then drive the screw hole block 34 to move, and then drive the connecting rod 35 and the mounting plate 36 to move, and then drive the screening push plate 312 to move, so that the shrimp seedlings can be active and move forward, and then can be screened out from the screening hole slot;

[0036] When oxygenation is required, the third motor 44 is started so that the active rod 45 can drive the active impeller 46 to rotate, and then drive the active gear 48 to rotate, so that the active gear 48 can drive the driven gear 49 to rotate, and then drive the driven impeller 410 to rotate to increase oxygen.
