Problems solved by technology

Although this device can realize the hatching separation and collection of shrimp seedlings, the overall structure of the device is complex, and the parts are fixedly connected, which is not easy to disassemble. There is no isolation between the breeding shrimp parents in the hatching box or the lower hatch collection box, and the parents are prone to fight, which affects the survival rate of the breeding shrimp

Embodiment 1

[0026] Such as Figure 1 to Figure 2 As shown, the present invention discloses a hatching separation and collection device for shrimp seedlings, comprising a collection box 1, a hatching frame 2, and a floating block 3, the floating block 3 is arranged on the hatching frame 2, and the hatching frame 2 is suspended in the collecting box by the floating block 3 Above 1, an isolating mechanism 4 is provided in the hatching frame 2, and the isolating mechanism 4 divides the hatching frame 2 into a plurality of compartments.

[0027] The shrimp hatching separation and collection device of the present invention has a simple overall structure. The hatching frame 2 is suspended above the collection box 1 by means of a floating block 3, and a non-fixed connection is adopted between the hatching frame 2 and the collection box 1, which is convenient for disassembly and assembly, and the hatching The frame 2 is provided with an isolation mechanism 4, through which the isolation mechanism ...

Embodiment 2

[0032] Such as image 3 As shown, this embodiment is basically the same as Embodiment 1, the difference is that in this embodiment, the isolation mechanism 4 is a tubular mechanism, further, in a preferred embodiment, the tubular mechanism is a PVC pipe, and the height of the PVC pipe is 10cm ~15cm, the diameter of the PVC pipe is 15cm~20cm. The isolation between the parents can be realized by the PVC pipe having a certain height, so as to avoid fighting between the parents.

Embodiment 3

[0034] Such as Figure 4 As shown, this embodiment is basically the same as Embodiment 1, the difference is that in this embodiment, the collection box 1 is a frame type collection box, and the side walls and the bottom wall of the frame type collection box are all provided with nylon nets, further Yes, in this embodiment, the mesh size of the nylon mesh is 60 to 80 mesh (that is, the mesh of the mesh is 250um to 180um). Further, in a preferred embodiment, the frame collection box is a wooden frame collection box. During installation, first the floating block 3 is installed on the surrounding wall of the hatching frame 2, then the hatching frame 2 is put into the frame type collection box, the floating block 3 can provide the hatching frame 2 buoyancy to prevent the hatching frame 2 from sinking excessively, and at the same time It acts as a block to prevent the wooden frame collection box from floating too much, and the position and size of the floating block 3 can be adjust...

Abstract

The invention discloses a shrimp seed hatching, separating and collecting device. The device comprises a collecting box, a hatching frame and a floating block, wherein the floating block is arranged on the hatching frame, the hatching frame is suspended above the collecting box through the floating block, an isolating mechanism is arranged in the hatching frame, and the hatching frame is divided into a plurality of compartments by the isolating mechanism. The device has the advantages of being simple in structure, convenient to disassemble and assemble and the like, fight among parents can beavoided, parents and seeds can be separated in time, and shrimp seeds can be conveniently collected in a centralized mode.

Description

technical field [0001] The invention mainly relates to the technical field of aquaculture, in particular to a device for separating and collecting shrimp seedlings. Background technique [0002] The reproduction of shrimp mainly includes several important stages such as fertilized egg, nauplius, shrimp seedling and adult shrimp. Existing practitioners in the prior art have designed shrimp breeding and hatching devices, such as Chinese patent CN201610401188. Composition of sewage pipes. Although this device can realize the hatching separation and collection of shrimp seedlings, the overall structure of the device is complex, and the parts are fixedly connected, which is not easy to disassemble. There is no isolation between the parents of the species of shrimp in the hatch or the lower hatch collection box, and the parents are prone to fights, which affects the survival rate of the species of shrimp. Contents of the invention [0003] Aiming at the technical problems exi...
