Device for cultivating lower animal with function for switching between air inflation and water feed

Abstract

The invention relates to a lower animal breeding device, particularly to a lower animal breeding device having an inflating influent switching function, comprising a cabinet arranged with drain air holes, a breeding carrier is arranged in the cabinet, an inflating and intake conduit switching device is arranged in the breeding carrier of the cabinet, comprising a central main conduit arranged vertically, a gas tube and a gas inlet pipe are arranged on top of the central main conduit, two-five tapping points are arranged on the central main conduit; a branch pipe is respectively connected on two sides of the main conduit of each tapping point; a secondary branch pipe is respectively connected on two sides of the end of the branch on the second or the third tapping point; a small hole of 0.5-1.5 mm is arranged every 3-5 cm on the conduit wall of the branch pipe and the secondary branch pipe. The invention releases air bubbles and water vapor up and down, backwards and forwards, left and right in turn in the middle of the solid breeding carrier, evenly keeps carrier breeding humidity and ventilation which is suitable for breeding bloodsuckers.

Description

technical field [0001] The invention relates to a lower animal breeding device. Background technique [0002] With the continuous development of the medicinal value of lower animals such as leeches, the demand for them continues to increase. However, with the continuous consumption of natural resources in recent years, the only way to solve the shortage of leech resources is to carry out artificial breeding. The artificial breeding of leeches requires a factory-like high-density three-dimensional breeding environment, because in this way it can have the advantages of less land occupation, saving valuable land resources; high breeding output, controllable breeding conditions and product quality; at the same time, it can greatly shorten the life of leeches The growth cycle can improve its reproduction rate, cocoon production rate, egg laying rate, hatching rate, seed survival rate and commercial leech growth rate; in addition, factory production can also effectively guarantee t...

Problems solved by technology

The technical problem to be solved in this prior art is to provide a leech breeding box that prevents leeches from escaping during the breeding process, is easy to catch, and is easy to change water. It does not involve the control and improvement of the leech breeding environment, because leeches are mainly It grows in ponds or field ponds, so this culture box can't really solve the problems that need to be solved in factory high-density culture

[0005] Chinese utility model patent specification CN2765471Y (application number is: 200520053381.6) discloses a kind of "leech breeding pond escape device" and Chinese utility model patent specification CN2834167Y (application number is: 200520098310.8) discloses "leech breeding anti-escape pond", which The main purpose is to prevent the leeches from escaping, and the leeches are directly bred in ponds or ponds in the field, so it is not a real factory high-density artificial breeding

[0006] The main problem solved by the above-mentioned prior art is how to prevent the leeches from breeding from escaping. However, the key to artificial breeding of leeches is how to improve the breeding environment of leeches. The problem of realizing the controllable breeding environment

In the prior art, leeches are generally cultured directly in ponds or ponds in large fields. The controllability of the breeding process is poor, and a large amount of waste generated during the breeding is deposited on the bottom of the pond, which is difficult to discharge and clean, and the ventilation effect is not good. None of them can maintain uniformity. The humidity and ventilation of the breeding carrier are suitable for the requirements of leech farming. The three-dimensional breeding box
