Semi-floating egg incubator

Abstract

The invention relates to an incubator, and particularly to a novel semi-floating type egg incubation device. The novel semi-floating type egg incubation device comprises an inner ring, an outer ring and an annular net cage with a net paved on the bottom thereof, wherein a plurality of lengthways water spraying pipes with two sealed ends and communicated with a water inlet pipe are respectively and uniformly arranged on the outer sidewall of the outer ring and the inner sidewall of the inner ring of the annular net cage; a plurality of water outlet holes with the water outlet direction tangent to the outer ring of the annular net cage are formed in the lengthways water spraying pipes which are located at the outer sidewall from upside to downside; a plurality of water outlet holes with the water outlet direction tangent to the inner ring of the annular net cage are formed in the lengthways water spraying pipes which are located at the inner sidewall from upside to downside; a plurality of transverse water spraying pipes which are communicated with the water inlet pipe and have two sealed ends are annularly and uniformly arranged on the bottom of the annular net cage; a plurality of water spraying holes having an included angle of 45 degrees with the bottom of the annular net cage are formed along the length direction of the transverse water spraying pipes. The novel semi-floating type egg incubation device is compact in structure and relatively good in permeability, ensures real-time exchange of water inside and outside the net cage in the incubation process, realizes circulation use of water for incubation, and is high in work efficiency.

Description

technical field [0001] The invention relates to an incubator, in particular to a semi-floating egg hatching device. Background technique [0002] As a traditional egg hatching equipment, the hatching ring is mainly used for semi-floating eggs or sticky eggs after debonding, such as the four major family carp, dace, bream, mandarin carp, carp, crucian carp, and loach. Its structure is mostly made of concrete or bricks coated with cement, generally with a diameter ranging from 3 to 8m, and 1m inside the ring road. 3 The water body can hatch 500,000 to 1,000,000 fertilized eggs. The disadvantages of this hatching equipment are that it occupies a large area, is expensive, and needs to be equipped with uninterrupted water sources, resulting in serious waste of water resources, low hatching density and hatching efficiency, heavy workload in the hatching process, and 24 staff members are needed in the fry hatching process. On duty every hour, regularly brush and clean the inner r...

Problems solved by technology

The disadvantages of this hatching equipment are that it occupies a large area, is expensive, and needs to be equipped with uninterrupted water sources, resulting in serious waste of water resources, low hatching density and hatching efficiency, heavy workload in the hatching process, and 24 staff members are needed in the fry hatching process. On duty every hour, regularly brush and clean the inner ring sieve silk filter to maintain its permeability and avoid water overflowing. This hatching facility is no longer suitable for the development needs of the modern breeding and breeding industry.
