Preferably, the water outlet of the inlet pipeline 1 is located at the bottom of live-box 2, can have water outlet and running water concurrently
The function of water body inflation oxygen supply in case 2.
Preferably, the sink 3 is tubular sink；The width of the side plate of the sink 3 is not less than 10cm, width
It is preferably controlled between 10mm-20mm, 3 inner side plate rough surface of sink, achievees the purpose that to meet that miniflow water and crayfish creep.
Preferably, 5 appearance and size of crayfish collector is less than live-box 2, and 5 top surrounding of crayfish collector is set
Edge is equipped with, so that crayfish collector 5 can flexibly take out out of live-box 2；In described 5 symmetrical two sides of crayfish collector
Wall or four side walls are provided with ordered series of numbers osculum, draining during easy to take out.
Compared with prior art, the beneficial effects of the invention are as follows：
Biomimetic type crayfish finishing device of the present invention is clear in structure, is easy to make.Using this crayfish finishing device, miniflow water in
Poured in from bottom to top in live-box, pond is flowed into from the top down through sink, crayfish, which can brave against the current, activity or looks for food, by crayfish
It during collector, can fall into crayfish collector, so as to achieve the purpose that to catch but also reduce damage, while can also carry
The purpose of high weed survival rate, good guarantee is provided for crayfish fishing in breeding production.

Embodiment
In order to make the present invention technological means, feature, reached purpose and effect it is easy to understand, below in conjunction with the accompanying drawings and
Embodiment, the technical solution that the present invention is further explained.
As shown in Figs. 1-3, a kind of biomimetic type crayfish finishing device, including live-box 2, crayfish collector 5, the live-box
2 are equipped with inlet pipeline 1, and inlet pipeline 1 penetrates live-box 2 from 2 side wall of live-box, and the water outlet of inlet pipeline 1 is located at live-box 2
Bottom, the water inlet end of the inlet pipeline 1 is provided with flow rate of water flow switch 7；Inlet pipeline 1 is provided with oxygenation branch 8, increases
Oxygen branch 8 is located at the water inlet end of inlet pipeline 1；Another side wall of live-box 2 is provided with inclined sink 3, the inclination of sink 3
Angle is to be penetrated through with the bottom of live-box 2 into 30 ° of angles, notch and the live-box 2 of 3 upper end of sink, and the lower end of sink 3 is reinforced
Muscle 4 is fixed with live-box 2；The crayfish collector 5 that can flexibly take out, the crayfish collector 5 are provided with the live-box 2
It is provided with crayfish entrance 6 corresponding with 3 upper end notch of sink to climb into easy to crayfish, crayfish entrance 6 is equipped with crayfish collector 5
Side wall and draining when being provided with ordered series of numbers osculum with another side wall of the sidewall symmetry easy to take out.
The material of the inlet pipeline 1 is Φ 40PPR tubing.
The material of the live-box 2 is stainless steel, and size is 1200mm × 800mm × 1000mm (length × width × height), away from
From rectangular opening is provided with 2 upper edge 100mm of live-box, rectangle pore size is 1000mm × 150mm, is made on live-box 2 and sink 3
The notch through connection at end.
The sink 3 is the tubular sink of stainless steel, and the notch of sink is rectangle, and size is 1000mm × 150mm.
Between 10mm-20mm, 3 inner side plate rough surface of sink, reaches and meets miniflow water and chela the width of the both sides plate of sink 3
