Embodiment Construction
[0009] Such as figure 1 As shown in the fry hatching device, the reservoir 1 is connected to the water outlet pipe 3 by the water pump 2, and the outlet of the water outlet pipe 3 is provided with a water distribution tank 4, and the oxygen cylinder 18 is connected with the water distribution tank 4 through the oxygen increasing pipe 19, and the water distribution tank 4 is provided below. There are several water distribution pipes 5, and the valves 6 and water injection nozzles 7 matched therewith. The hatching device 8 is arranged below the water injection nozzle 7. The hatching device 8 includes a V-shaped container device 13, a water collection ring 14, a beam flow ring 15 and The gate 17 is connected to the water collecting circle 14 above the V-shaped container device 13, and the beam flow circle 15 is located in the water collecting circle 14. The direction of the center line is close, and there is a water outlet on the upper part of the beam coil 15. The gate 17 is ins...

The invention discloses a fish fry hatching device. The fish fry hatching device is structurally characterized in that a reservoir is connected with a water outlet pipe by a water pump, a water distribution groove is formed in a position below an outlet of the water outlet pipe, an oxygen cylinder is connected with the water distribution groove by an oxygenation pipe, a plurality of water distribution pipes are connected with the lower side of the water distribution groove and are connected with water injection nozzles by valves, hatchers are arranged below the water injection nozzles and comprise V-shaped containers, water collecting rings, flow constraining rings and gates, the water collecting rings are connected with the upper sides of the V-shaped containers, the flow constraining rings are positioned in the water collecting rings, the lower sides of the flow constraining rings are connected with the V-shaped containers, the upper sides of the flow constraining rings are drawn together towards the center lines of the V-shaped containers, a water outlet is formed in each flow constraining ring, gate openings are inserted in the water outlets, water outlet pipes are arranged onthe water collecting rings, fish storage grooves are formed in positions below the water outlet pipes and are particularly formed in a tray, the tray is positioned on a fixing support, a water returnpipe is arranged on the tray, and an outlet of the water return pipe is formed in a position above the reservoir. The fish fry hatching device has the advantages that the occupied areas can be reduced, materials can be saved, and the fish fry hatching device is low in water change volume and roe impact damage degree.
Description
technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a fry hatching device. Background technique [0002] There are many disadvantages of current fry hatching equipment, such as large floor area, high material consumption, large amount of water exchange, and large impact damage to fish eggs. Contents of the invention [0003] The invention aims at the deficiencies of the prior art, and provides a fry hatching device which saves floor space, consumes less material, and has little impact damage to fish eggs. [0004] For realizing above-mentioned object, the technical scheme that the present invention adopts is: [0005] Fish hatching device, the reservoir is connected to the water outlet pipe through the water pump, there is a water distribution tank under the outlet of the water outlet pipe, the oxygen cylinder is connected to the water distribution tank through the oxygen increasing pipe, and several water distribution pi...
