Device suitable for multi-layered stereo factory culture of whitmania pigra

Abstract

The invention discloses a device suitable for multi-layered stereo factory culture of whitmania pigra. The device comprises a culture box which is provided with a sewage collecting trench and a culture tank; the sewage collecting trench is positioned under one side of the culture tank; three attachment walls are fixed at a bottom end inside the culture tank; the three attachment walls are arrangedin the horizontal direction with equal intervals; an inner bottom of the sewage collecting trench is provided with a sewage draining port; drainage pipe is fixed inside the sewage draining port; thedrainage pipe is installed at one side of one attachment wall in the middle; the drainage pipe is provided with a holed tube wall segment and a solid tube wall segment; the holed tube wall segment ispositioned at one side of the solid tube wall segment. The invention provides a pluggable water level control sewage pipe which is composed of a holed tube wall segment and a solid tube wall segment.By changing the insertion end of the sewage pipe, dirt of different sizes in the culture trough can be discharged according to different water levels. In addition, the water quality can be purified without affecting the growth of the aquaculture product.

Description

technical field [0001] The invention belongs to the technical field of industrial farming of leeches, and in particular relates to a wide-body golden leech device suitable for multi-layer three-dimensional industrial farming. Background technique [0002] Wide-bodied golden leeches, commonly known as leeches, belong to the phylum Annelida, class Hirudophylum, order Hirudognathidae, and the family Leechidae. It grows and reproduces in inland freshwater waters. It is a traditional special medicinal aquatic animal in my country. Leeches contain leeches, which can Delay and hinder blood coagulation, so as to have anticoagulant effect. The leech element extracted from leeches is very effective in dilating blood vessels, reducing blood viscosity, and increasing blood circulation. Now it has been developed to treat stroke, high blood pressure, blood stasis, and amenorrhea. , bruises and other drugs and various health products, cosmetics. The market demand is soaring, and the market ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of wide-body gold wire leech device suitable for multi-layer three-dimensional factory culture, to solve the above-mentioned background technology that proposes that the drain is easily blocked by bait, especially the nails of snails, and the water does not come out, and the leeches pass through. The water mouth is easy to be sucked and difficult to get out and die and the water quality is easy to deteriorate. After the stocking density is high, the leeches will have nowhere to adsorb or accumulate in large quantities, resulting in the spread of disease and death.
