Problems solved by technology

The fish fry sorting device of the invention can adjust the thickness and interval of the grids according to the requirements of the target specifications, so as to screen and separate fish of different specifications in a short time, shorten the separation time and avoid fish body injury, but the fish fry screened out by the invention still needs manual labor. Fish fry may be injured while fishing. Some fry will die if they lack oxygen during the screening process. If the breeding pond is used for a long time without cleaning, dirt will appear on the inner wall of the breeding pond, which will also affect the health of the fry.

Embodiment 1

[0019] like Figure 1-2 As shown, the fish fry screening equipment includes a culture pond 4, a grid unit 3, and a fishing net 8. The inside of the culture pond 4 is provided with a grid unit 3, and the front and rear ends of the culture pond 4 are provided with outlet pipes 6, and the water outlet of the outlet pipe 6 is Be connected with small-scale cultivation case 7, and small-scale cultivation case 7 connects cultivation case 4 bottoms by water pipe 5. The fish fry screened out by this device in the screening process will swim to the small breeding box through the water outlet pipe, so there is no need for manual salvage, saving time and effort. Has been stored in the breeding pond to produce bacteria that affect the health of fry.

[0020] Grid unit 3 comprises guide rail 11, and guide rail 11 is respectively placed on the upper and lower ends of culture pond 4 and guide rail 11 is arranged at intervals in parallel, and guide rail 11 is the rectangular parallelepiped of...

Embodiment 2

[0026] like Figure 1-2 As shown, before screening fish fry, the staff first samples and measures the cultured fish fry samples in the culture pond 4, measures parameters such as the weight and body width of the cultured fish, and after determining the positive correlation between body width and body weight and body length, set Screen the target specifications of the graded cultured fish, and then select the narrow fish to determine and adjust the distance between the grid bars 2 of the separation grid, and then flush the air bag 802 on the fishing net 8 with a certain amount of air to make the air bag 802 expand and compress The gap between the fishing nets can only allow the fry with a narrow fish body to pass through. Put the adjusted grid 2 into the culture pond 4, and the staff will hold the handles 1 at both ends of the fence and move from one end of the culture pond 4 to the other. , making the small-scale cultured fish pass through the grid bar 2 freely, and when pushe...

Abstract

The invention discloses a fry screening equipment, and belongs to the technical field of fry screening. The equipment includes an aquaculture pool, a grid unit and a fishing net; the grid unit is arranged in the aquaculture pool, the front end and rear end of the outer side of the aquaculture pool are provided with water outlet pipes, the water outlet ends of the water outlet pipes are connected with small aquaculture boxes, and the small aquaculture boxes are connected with the bottoms of the aquaculture boxes through water pipes. The fry screened out in the screening process swim into the small aquaculture boxes through the water outlet pipes, artificial fishing is not required, time and labor are saved, the small aquaculture boxes are connected with the aquaculture pool through the water pipes and play a role in water circulation, and the situation that water is always stored in the aquaculture pool and bacteria are thus generated and affect the health of the fry is avoided.

Description

technical field [0001] The invention belongs to the technical field of fry screening, and in particular relates to fry screening equipment. Background technique [0002] In general fisheries, the fry need to be screened before fry breeding, and the fry of different sizes are raised separately, so as to avoid the situation where big fish plunder small fish and compete with each other, and at the same time, fry of different sizes can absorb the fish fry. Nutrients that should be present during the growth stage, so as to achieve the effect of stable growth of fry. [0003] The prior art, for example, Chinese invention patent authorization document, the authorized announcement number is: CN 104137796 B, which discloses a fish fry classification device, which includes a plurality of grid units connected to each other through connectors; wherein the grid units include: guide rails , the number of guide rails is two, and the two guide rails are arranged in parallel at intervals. T...
