Description
[technical field]
The utility model relates to aquaculture technology, particularly relates to culture of Chinese mitten crab technical field.
[background technology]
The cultivation of crab kind is the basis of culture of Chinese mitten crab industry, along with the fast development of culture of Chinese mitten crab industry, culture of Chinese mitten crab area constantly expands, the demand of culture of Chinese mitten crab family to crab kind increases year by year, the cultivation of crab kind has become one of focus industry of people's concern, crab kind aquaculture is carried out in many raiser's investments, improving constantly in recent years along with culture of Chinese mitten crab technology, crab kind is thrown in and requires also to propose higher requirement, according to the requirement of the efficient cultural technique of river crab ecologic, the identical crab kind of size must be thrown in same pond, otherwise, will cause and strive food, shell is irregular, the phenomenon cut one another's throat, harvest time river crab specification irregular, yield poorly, deficiency in economic performance.For this reason, when throwing in crab kind, the crab kind of same size must be put in a suitable place to breed.
At present, crab kind sorts the main method relying on manual sorting of classifying, and not only sorting work amount is large, and manual sorting's cost is high, and the very difficult control of crab kind is in the same size.Although raiser drops into higher cost, the crab kind provided still can not meet the technological requirement that river crab is put in a suitable place to breed, and many culture of Chinese mitten crab families are all because crab kind sorting difficulty is large, often raise the river crab that size heterogeneity is larger, the rate of recapture is lower, results in a loss, and has to abandon culture of Chinese mitten crab.
How to solve the classification of crab kind to select, can ensure to select specification consistency, can reduce again and select cost, this is the technical barrier that crab kind raiser thirsts for solving most.
[utility model content]
The purpose of this utility model is to provide the classification of a kind of crab kind and selects device, and it can carry out classification fast and accurately to crab kind and select, and neither wants artificial hand-sort classification, can not damage crab kind again, classify with low cost.
The technical scheme that the utility model is taked is as follows:
Device is selected in the classification of a kind of crab kind, involving vibrations support, spring lead, spring body, spring fairlead, fixed mount, bottom separating sieve, N level separating sieve, top layer separating sieve and add crab bucket, electric vibrating parts are provided with in vibration support, it can produce frequency is 30 ~ 80HZ, amplitude is the vibration of 0.5 ~ 1.5 millimeter, 3 ~ 8 spring leads are provided with at the upper end face of vibration support, every root spring lead is set with spring body, the outer ring sleeve of spring body is contained in the endoporus of spring fairlead, spring fairlead is fixed on the bottom of fixed mount, fixed mount is provided with separating sieve that mesh diameter reduces step by step from top to bottom, the superiors are the maximum top layer separating sieve of mesh diameter, orlop is the minimum bottom separating sieve of mesh diameter, N level separating sieve is provided with between top layer separating sieve and bottom separating sieve, each layer separating sieve is all obliquely installed, the outlet of crab kind is provided with in the least significant end of every layer of separating sieve, inoculation cylinder is provided with in the below of crab kind outlet, be provided with in the upper end of top layer separating sieve and add crab bucket.
Further, the mesh diameter of top layer separating sieve is 2.5 centimetres, and the crab kind specification selected thus is≤50/jin, and the mesh diameter of bottom separating sieve is 1 centimetre, crab kind specification obtained thus is≤100/jin, and the mesh diameter of N level separating sieve is 2 centimetres ~ 1.5 centimetres.
Further, the inclination angle on each layer separating sieve and ground is 10 ° ~ 25 °.
Further, the incline direction circumference of each layer separating sieve evenly staggers mutually.
Further, fixed mount is equilateral triangle frame or regular polygon frame.
Be 30 ~ 80HZ because vibration support can produce frequency when sorting, amplitude is the vibration of 0.5 ~ 1.5 millimeter, fixed mount is by spring fairlead, spring body and spring lead are shelved on vibration support, fixed mount is provided with separating sieve that mesh diameter reduces step by step from top to bottom, the mesh diameter of top layer separating sieve is maximum, the mesh diameter of bottom separating sieve is minimum, be arranged between top layer separating sieve and bottom separating sieve and be provided with N level separating sieve, the mesh diameter of N level separating sieve is corresponding with corresponding specification crab kind size, each layer separating sieve is all obliquely installed, the outlet of crab kind is provided with in the least significant end of every layer of separating sieve, like this when the crab kind to be screened differed in size is poured on top layer separating sieve, the vibration of the little amplitude of high frequency forces crab kind to be in deflated state, now crab kind is in minimum state, under dither condition, crab kind can be rolled to low side along sorting compass screen surface from high-end, when running into mesh, the crab kind being less than mesh diameter is just fallen in next layer of separating sieve from mesh, the crab kind being greater than mesh diameter then falls into inoculation cylinder from the outlet of crab kind, so sorting step by step, just can will treat that the crab kind of sorting sorts out by size from top to bottom step by step, not only the efficiency of separation is high, and the crab kind accordance of same specification is high, crab kind can meet the technological requirement that river crab is put in a suitable place to breed.
