Description
【Technical field】
The present invention relates to aquaculture technology, more particularly to culture of Chinese mitten crab technical field.
【Background technology】
Crab farming is the basis of crab farming, and with the fast development of crab farming, culture of Chinese mitten crab area is continuous
Expand, culture of Chinese mitten crab family increases the demand of crab species year by year, crab farming turns into one of focus industry of concern, no
Few raiser's investment carries out crab farming industry, recently as the continuous improvement of culture of Chinese mitten crab technology, crab species is delivered and required
Higher requirement is proposed, according to the requirement of the efficient cultural technique of river crab ecologic, same pond must deliver size identical crab species,
Otherwise, will trigger strive food, shell is irregular, the phenomenon that cuts one another's throat, harvest time river crab specification it is irregular, yield poorly, pass through
Ji is of poor benefits.Therefore, when delivering crab species, it is necessary to put the crab species of same size in a suitable place to breed.
At present, the method that crab species sorting classification relies primarily on manual sorting, not only sorting work amount is big, manual sorting's cost
Height, and crab species are difficult that control is in the same size.Although raiser puts into higher cost, the crab species provided still can not be met
The technological requirement that river crab is put in a suitable place to breed, many culture of Chinese mitten crab families are all big because of crab species sorting difficulty, often raise the larger river of size heterogeneity
Crab, the rate of recapture is relatively low, results in a loss, it has to abandon culture of Chinese mitten crab.
How to solve crab species classification to select, both can guarantee that and selected specification consistency, and can reduce and select cost, this is crab species
Raiser most thirsts for the technical barrier solved.
【The content of the invention】
Device is selected it is an object of the invention to provide a kind of classification of crab species, it can carry out fast and accurately classification to crab species and select for a post
Choosing, both should not manually classify, crab species will not be damaged again, are classified with low cost in hand-sort.
The technical scheme that the present invention takes is as follows：
Device, including vibration support, spring lead, spring body, spring fairlead, fixation are selected in a kind of crab species classification
Frame, bottom separating sieve, N grades of separating sieves, top layer separating sieve and add crab bucket, are provided with electric vibrating part, its energy in vibration support
Generation frequency is 30~80HZ, and amplitude is 0.5~1.5 millimeter of vibration, and 3~8 bullets are provided with the upper end face of vibration support
Spring lead column, is set with spring body in every spring lead, and the outer ring of spring body is sleeved in the endoporus of spring fairlead,
Spring fairlead is fixed on the bottom of fixed mount, the separating sieve reduced step by step provided with mesh diameter from top to bottom on fixed mount,
The bottom separating sieve that the superiors are the maximum top layer separating sieve of mesh diameter, orlop is mesh diameter minimum, in top layer sorting
Provided with N grades of separating sieves between sieve and bottom separating sieve, each layer separating sieve is obliquely installed, is provided with the least significant end of every layer of separating sieve
Crab species are exported, and the lower section exported in crab species is provided with inoculation cylinder, and add crab bucket is provided with the upper end of top layer separating sieve.
Further, the mesh diameter of top layer separating sieve is 2.5 centimetres, and the crab species specification thus selected is≤50/jin, bottom
The mesh diameter of layer separating sieve is 1 centimetre, and thus resulting crab species specification is≤100/jin, and the mesh of N grades of separating sieves is straight
Footpath is 2 centimetres~1.5 centimetres.
Further, the inclination angle on each layer separating sieve and ground is 10 °~25 °.
Further, the incline direction of each layer separating sieve circumferentially uniformly mutually staggers.
Further, fixed mount is equilateral triangle frame or regular polygon frame.
Because vibration support can produce frequency in sorting for 30~80HZ, amplitude is 0.5~1.5 millimeter of vibration, Gu
Determine frame and vibration support is shelved on by spring fairlead, spring body and spring lead, be provided with net from top to bottom on fixed mount
The separating sieve that eye diameter reduces step by step, the mesh diameter of top layer separating sieve is maximum, and the mesh diameter of bottom separating sieve is minimum, sets
Provided with N grades of separating sieves between top layer separating sieve and bottom separating sieve, the mesh diameter and corresponding specification crab species of N grades of separating sieves are big
Small corresponding, each layer separating sieve is obliquely installed, every layer of separating sieve least significant end provided with crab species export, so when by size not
Deng crab species to be screened pour on top layer separating sieve when, the vibration of the small amplitude of high frequency forces crab species to be in deflated state, now crab
Plant and be in minimum state, crab species can be rolled along sorting compass screen surface from high-end to low side under the conditions of dither, when running into mesh,
Crab species less than mesh diameter are just fallen on from mesh in next layer of separating sieve, and the crab species more than mesh diameter are then exported from crab species
Fall into inoculation cylinder, so sort step by step, just crab species to be sorted can step by step be sorted out from top to bottom by size, not only divided
Efficiency high is selected, and the crab species accordance of same specification is high, and crab species disclosure satisfy that the technological requirement that river crab is put in a suitable place to breed.
