Description

A kind of device improving cray shrimp seedling transportation survival rate
Technical field
The present invention relates to aquatic product sprout transport utensil, be specifically related to a kind of device improving cray shrimp seedling transportation survival rate.
Background technology
Procambius clarkii (Procambarusclarkii) is a kind of fresh water shrimp, also known as crayfish, cray etc., be the important economic aquatic animal of China, through popularization cultivation for many years, now developed into the main cultivation object of economic shrimps, annual value of production reaches tens billion of RMB.
In development scale Procambius clarkii breeding production process, constantly perfect along with industrial chain, cray shrimp seedling is bred and is become shrimp aquaculture progressively to divide the work, and the transport of shrimp seedling to have become in Procambius clarkii breeding production process an important link.In order to improve the survival rate of shrimp seedling transport, prawn seedling carrier has comparatively strict requirement.The method of existing transport cray shrimp seedling is mainly divided into the dry fortune of band grass and Transportation, to be with the dry fortune of grass more in production.Transport utensil mainly comprises Double-layer oxygen bag, canvas bag, running water car, frame of plastic, bubble chamber etc., most of carrier lamps structure is simple, function singleness, as oxygen bag and canvas bag support owing to not having support body, freight volume is less, and the ability that opposing destroys, easily cause shrimp seedling dead because extruding mutually injured infection; With the transport of running water car, water consumption is large, and the travel time is long, and cost of transportation is high; Pasture and water transport is placed in frame of plastic and bubble chamber, freight volume is more, but haulage time is long, shrimp shoot survival percent is low, need not timing to spray water and make pasture and water and shrimp seedling keep moistening, otherwise shrimp seedling is because of the too fast dry lack of water of shrimp soma and dead of causing of shrimp surface moisture evaporation, the movement requirement based on guarantee shrimp seedling survival rate can not be met well.
Summary of the invention
The object of the invention is the deficiency for prior art exists and imperfection, a kind of device improving cray shrimp seedling transportation survival rate is provided, shrimp seedling stress reaction can be reduced by this device transport cray shrimp seedling, improve shrimp seedling freight volume and shrimp shoot survival percent in transit, reduce cost of transportation, make full use of transport usefulness.
The object of the invention is to be achieved through the following technical solutions:
A kind of device improving cray shrimp seedling transportation survival rate, comprise and receive seedling box and canister, described canister comprises casing and case lid, being provided with at least one grid and receiving seedling box for placing, being provided with freezing tank for placing ice cube between grid and cabinet wall in described casing; Described seedling box of receiving comprises box body, lid, is equipped with moisturizing layer in described box body, and 4 sidewalls of described box body arrange at least a line first air-vent, and 4 sidewalls of described lid are provided with second air-vent corresponding with the first air-vent.
Preferably, the upper edge edge of at least one sidewall of described casing is provided with semicircular indentations, is convenient to picking and placeing of case lid.
Preferably, the material of described casing and case lid is foamed plastics, and foamed plastics has good heat-insulating property, can make to keep suitable temperature for a long time in canister.
Preferably, in described casing, being provided with two grids, between adjacent two grids, being provided with the second freezing tank for placing ice cube.
Preferably, the material of described moisturizing layer is sponge.
Preferably, described in receive seedling box body 4 sidewalls on two row first air-vents are set, adjacent rows first air-vent is being staggered of corresponding room.
Preferably, the diameter of described first air-vent is greater than the diameter of the second air-vent, both ensure that receiving seedling box communicated with outside air, turn avoid to receive the too fast evaporation of moisture in seedling box, is conducive to keeping shrimp seedling shrimp body moistening.
Preferably, described receive to be provided with bottom seedling box body support convex pad, to make in transportation the air circulation between seedling box of receiving of superposition mutually.
When using apparatus of the present invention transport shrimp seedling, toward freezing tank in, put into ice cube, the loading of shrimp seedling is received in seedling box, then is positioned over receiving seedling box stacked in multi-layers in the grid of canister.
Compared with prior art, the invention has the beneficial effects as follows:
Apparatus of the present invention owing to being provided with the freezing tank for filling ice cube in casing, and the temperature in the reduction transport case that the ice cube in freezing tank can be suitable, prevents shrimp seedling Yin Wendu too high and dead; Moisturizing layer can keep the humidity received in transportation in seedling box effectively, prevents shrimp seedling dead because of dehydration.The waste gas that shrimp seedling produces can be discharged from the air-vent received seedling box, completes ventilation; Simultaneously the diameter of the first air-vent is greater than the diameter of the second air-vent, turn avoid to receive the too fast evaporation of moisture in seedling box, is conducive to keeping shrimp seedling shrimp body moistening.Apparatus of the present invention can reduce cost of transportation, make full use of transport usefulness, decrease shrimp seedling stress reaction, reduce the lethality of shrimp seedling in transportation largely, meet the shrimp movement requirement alive based on ensureing shrimp seedling survival rate preferably.
