Description
Technical field
The utility model is related to field of aquaculture devices, are specifically related to harvesting classification dress in a kind of bastard halibut and plaice seedling room
It puts.
Background technology
Biology in living nature between type there are a kind of behavior for cutting one another's throat or killing and devouring, referred to as autotomy phenomenon, this
Kind phenomenon is more universal, and strict difinition is to eat the other individuals of same type by part or whole to cause by devourer's death
The phenomenon that.This phenomenon is also prevalent in fish, when being happened in some important economic species, will be caused very big
Economic loss.
In view of the maximization of economic interests, inevitably there are the high feelings of the close degree of bias of fish culture during industrial aquaculture
Condition, under this situation, the mutual growth differences of numerous fish result in a part of immature shoal of fish that cannot obtain giving birth to it
Long corresponding enough nutrition, thus more influences the growth of the immature shoal of fish, between the individual for increasing contemporaneity fry
Difference.And this imagination has just more aggravated autotomy phenomenon, gobble it is small, while big fish during small fish is eaten it is also possible to injured.
And the fish body after dead breakage is easy to that germ is caused to infect, and pollutes entire breeding environment, causes to drop in production over a large area or whole
The fish in a fishpond all infects.
In order to prevent this situation, current main method is fed according to the progress of the specification of fry and time-division pond, by phase
The fry of nearly specification is positioned over same place and is managed, and ensures that nutrition provides, can protect the immature shoal of fish to the greatest extent in this way
Growth.
And current technology scheme is to be stayed to put small screening greatly with sieve, but need by the fry in entire fishpond into
Row mesh screen, expends the time very much, and sieve can also cause to damage to fry；Have again be exactly be utilized fry against the current with it is crowded
The features such as escape, devises sieving equipment, although having certain improvement with original sieving mode in this way, efficiency increases,
But it is positioned in device with being required in pond pulling fry out as earliest sieving mode, the damage for increasing fry is several
Rate, and equally set during sieving equipment and not only waste time but also troublesome in poeration, expend strength.
Utility model content
According to more than the deficiencies in the prior art, the utility model provides harvesting grading plant in a kind of bastard halibut and plaice seedling room,
Can fry effectively be sieved by one man operation, operational capacity is strong, efficient, small to fry damage.
The technical solution that uses of the technical issues of the utility model solves for：Two including front-rear direction setting intersect
Collector rod handle, the two collector rod handles are hinged to pliers shape, the collector bar in infall by collector shaft
Handle is set as collector handle, two institutes using collector shaft as front-end and back-end, the rear end of the collector rod handle is divided into
State the left and right sides that collector rod handle front end is respectively fixedly connected with the collector spacer screen for having lower arcuate surface in one, the collector
The rear end bottom surface of spacer screen offers a through-hole, and the through-hole is connected with the top of the collector string bag, and the collector string bag includes
The tubular collector side net of collector sieve and the up/down perforation being downwardly extending along bore periphery, the collector sieve can
Dismounting is set on the inside of the bottom end of collector side net, and the collector sieve mesh size is collector side net and collector spacer screen
10~50 times of mesh.
Apparatus above only needs one hand-held collector handle can be operated, because two collector rod handles are hinged, institute
The distance between front end with two collector rod handles can be adjusted according to fishpond size.
Device is positioned in fishpond by hand-held collector handle to be screened back and forth, and fry can enter collector net with flow
Pocket, the collector sieve in the collector string bag can carry out the replacement of size according to the size of fry to be sieved, facilitate a variety of rule
The screening of lattice fry, smaller unwanted fry will flow into fishpond from collector sieve, will not be held by the collector string bag
It carries, greatly reduces the damage probability to immature fry.
Wherein, preferred embodiment is：
The mesh of collector side net and collector spacer screen is 20 mesh, and aperture is 830 μm.
The body of rod of each collector rod handle front end bends inwards to form section A that angle is 120 ° and section B, described
