Abstract
The utility model discloses a kind of pearl spat cultivation aufwuch removes knife, the one side of its cutter hub offers the edge of a knife of concaved circular cambered surface in.Using the circular arc line blade of arc surface, the aufwuch at aufwuch on pearl spat housing and recess position can rapidly be removed, the growth scale that injure pearl spat edge is avoided simultaneously, pearl spat individual health is promoted to grow, make the pearl spat cultivation speed of growth accelerate, improve into shellfish and form rate.
Description
Technical field
The utility model belongs to aquaculture aid, and more particularly to one kind is used for removing cultured pearl spat shell surface
The cutter of aufwuch.
Background technology
At present, during shallow sea water carries out cultured pearl spat, as planktonic organism is enriched very much, accelerate
The amount reproduction of aufwuch (e.g., rattan shell, lime worm, sponge etc.), causes and is covered by bioadhesion on pearl spat housing,
Pearl spat is difficult to open seedling mouth, so as to affecting to breathe, ingesting, grow, causes pearl spat cultivation poor growth or death, raw
Long environment is compromised.Therefore, in the daily management mission of pearl spat cultivation, the attachment on pearl spat housing is removed in time
Biology is requisite operation.In order to remove aufwuch, common stylet is usually used and manually removes pearl spat housing
On aufwuch, but, as pearl spat surface of shell assumes recess, and the scale at shell edge is vigorous, traditional straight line
During shape pocket knife use, recess position can only be removed with point of a knife, meanwhile, in order to avoid point of a knife scratches pearl spat housing
Marginal growth scale, can only be meticulous during operation, makes operating efficiency step-down, if scale is damaged accidentally, or even individual growth
Stagnate, cultivation individual growth can be made into deformity or disability shape, rate is formed so as to reduce into shellfish.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of raising and removes operating efficiency, and effectively can prevent from scratching
The pearl spat cultivation aufwuch of housing removes knife.
In order to solve above-mentioned technical problem, the technical solution of the utility model is：A kind of pearl spat cultivates aufwuch
Knife is removed, is made up of cutter hub and sleeve shank, the one side of the cutter hub offers the edge of a knife of concaved circular cambered surface in.
Using above-mentioned technical proposal, as the knife-edge design of cutter hub is into interior concaved circular cambered surface, using the circular arc line knife of arc surface
Sword, can rapidly remove the aufwuch at aufwuch on pearl spat housing body and recess position, while avoiding hindering
The growth scale at evil pearl spat edge, promotes pearl spat individual health to grow, and makes pearl spat cultivation speed accelerate, improves
Rate is formed into shellfish.
Description of the drawings
Fig. 1 is the main structure diagram that pearl spat cultivates that aufwuch removes knife.
Fig. 2 is the side structure schematic view that pearl spat cultivates that aufwuch removes knife.
Specific embodiment
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described further.Here it should be noted that
For the explanation of these embodiments is used to help understand the utility model, but do not constitute to restriction of the present utility model.This
Outward, as long as involved technical characteristic in the utility model disclosed below each embodiment does not constitute conflict each other
Can just be mutually combined.
As depicted in figs. 1 and 2, pearl spat aufwuch is removed knife and is made up of cutter hub 1 and sleeve shank 2.Cutter hub 1 is overall to be in
Bullet shape, length are 20～25cm.Sleeve shank 2 is overall in hollow drum or cylindroid shape, and length is 20～
30cm.Cutter hub 1 is plugged in sleeve shank 2, and both connection coincidence part length is 2～2.5cm.The one side of cutter hub 1 is processed into
For the edge of a knife 3, arc surface of the edge of a knife 3 in indent, circular arc 12～16cm of chord length, the circular arc line of arc surface is used as blade.
When removing the aufwuch that knife is removed in pearl shell seedling body using pearl spat aufwuch of the present invention, user's
In thumb and forefinger plug-in-sleeve handle, another thumb and forefinger grip pearl spat are individual.With the activity of thumb and forefinger,
The aufwuch gone in pearl shell seedling body can be removed using round camber line blade, effectively by pearl spat individuality recess portion
The aufwuch of position removes, and due to the marginal growth scale of the curved shape of the edge of a knife not easy damaged pearl shell seedling body, is conducive to pearl
Growth and ingest that spat cultivates, promote pearl spat healthy growth, while improving the survival rate of pearl spat and forming rate.
Embodiment of the present utility model is explained in detail above in association with accompanying drawing, but the utility model is not limited to be retouched
The embodiment that states.For a person skilled in the art, in the case of without departing from the utility model principle and spirit, right
These embodiments carry out multiple changes, modification, replacement and modification, still fall within protection domain of the present utility model.
