Artificial large-scale incubator for plateau fishes

Technical Field

The utility model relates to an aquaculture field, especially an artificial scale incubator of plateau fish.

Background

The fertilized eggs of the plateau fishes easily die in a large amount due to physical shock in the early stage, the existing incubation mode is still water or microflow water incubation in an incubation frame, and the incubation mode has the problems of large occupied area, easy oxygen deficiency death, water mold breeding, huge workload when picking the dead eggs and the like. Therefore, there is an urgent need to improve the hatching method of fertilized eggs of plateau fish to improve the production efficiency.

SUMMERY OF THE UTILITY MODEL

The incubator occupies small area, effectively reduces the manpower input, and is suitable for large-scale artificial propagation of the plateau fishes.

The utility model adopts the technical proposal that:

the utility model provides an artificial scale incubator of plateau fish, includes hatching bucket, overflow tank, guiding gutter and inlet tube, the play water end of inlet tube inserts and the delivery port is close to from the open-top of hatching bucket the bottom of hatching bucket, the upper end lateral wall of hatching bucket has around the overflow tank, the top of hatching bucket is higher than the lateral wall of overflow tank, the lateral wall of overflow tank is equipped with the gap, the gap is connected the one end of guiding gutter, the other end of guiding gutter is outlet and downward sloping setting, the bottom of hatching bucket is convex bottom surface.

Upper portion in the hatching bucket is provided with radial extension board, the center of extension board is equipped with and supplies the trompil that the inlet tube penetrated, be equipped with the cavity that supplies water and spill over around the trompil.

The play water end lateral wall circumference equipartition of inlet tube has a plurality of blades, the end of blade can just lean on the convex bottom surface of leaning on the hatching bucket.

The distance between the water outlet of the water inlet pipe and the bottom surface of the incubator is 2-3 mm. The diameter of the fish eggs is 2.5-4mm, water in the incubator can flow backwards under the condition of sudden power failure, and the gap can be set between 2-3mm, so that the fish eggs can be prevented from flowing backwards out of the incubator along the water inlet pipe.

The inner diameter of the water inlet pipe of the utility model is 1.0-3.0 cm. The pipe diameter can conveniently control the flow velocity of water, so that the water body in the hatching barrel integrally rolls under the action of water column reflection at the bottom of the barrel, fish eggs roll up and down and do not overlap at the bottom of the incubator, and meanwhile, the hatching of the fish eggs cannot be influenced due to vibration, the hatching of the fish eggs in the incubator is ensured, the membrane outlet rate is high, and the distortion rate is low.

The hatching barrel of the utility model is a transparent barrel.

The incubator is arranged on the inclined ground, and the lower side of the ground is provided with a water outlet.

The utility model has the advantages that:

1. the incubator is designed to be capable of feeding water from top to bottom, water flow collides with the arc-shaped bottom surface of the incubation barrel under the action of gravity, water columns are reflected back to form water flow from bottom to top, the water flow speed is stable, fertilized eggs can be kept to roll up and down uniformly, and no dead angle exists on the arc-shaped bottom surface, so that the roes can not be accumulated at the bottom and can not die.

2. The fish egg incubator has the advantages that the occupied area is small, and the number of fertilized eggs capable of being incubated in unit area is greatly increased; after the fertilized eggs die, the fish eggs turn white, the density becomes small, and the fish eggs can flow out from an overflow port at the upper end of the incubator along with water flow, so that the dead eggs do not need to be removed, and a large amount of manpower and financial resources are saved.

3. The top end of the hatching barrel is provided with an annular overflow groove, and flowing water gushes out from the top end of the hatching barrel, enters the annular overflow groove and flows away through the diversion groove. Because the fish eggs are not easy to gush out along with the overflow due to the upward gushing resistance, the annular overflow groove is arranged to keep the outside of the hatching barrel clean, the top of the hatching barrel is higher than the overflow groove, and the water in the overflow groove is ensured not to flow back into the hatching barrel.

4. The incubator is arranged on the inclined ground, water overflowing from the incubator is directly drained to the ground and is drained away from the water outlet, the operation is convenient, and a large amount of water cannot be accumulated on the ground.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Example 1

As shown in fig. 1, the artificial large-scale incubator for plateau fishes comprises an incubation barrel 31, an overflow groove 33, a diversion groove 34 and a water inlet pipe 32, wherein a water outlet end of the water inlet pipe 32 is inserted from an opening at the top of the incubation barrel 32, a water outlet is close to the bottom of the incubation barrel 32, the overflow groove 33 is arranged on the outer side wall of the upper end of the incubation barrel 32 in a surrounding mode, the top end of the incubation barrel 31 is higher than the side wall of the overflow groove 33, an overflow port is arranged on the side wall of the overflow groove 33 and connected with one end of the diversion groove 34, the other end of the diversion groove 34 is a water outlet and is arranged in a downward inclination mode, and the bottom of the incubation barrel 31 is.
