Abstract
A kind of fish sieve of variable format, comprise hollow cylinder, the bottom of described cylindrical shell one sidewall have be in same level and pitch of holes equal one row side opening, the bottom of described another sidewall of cylindrical shell has arranges the corresponding exhausting hole in side opening position with described one, horizontal plane residing for through hole higher than side opening residing for horizontal plane, between corresponding side opening and through hole, be interspersed with grating.The utility model is by arranging the size of the quantity regulating fish mesh size of grating, thus the fish of screening different size, and sieve mesh specification standards, fry screening is evenly; Wherein grating is the perspex bar of round bar shape, and smooth surface can not hinder fish; Easily changing when damaging appears in grating; The utility model in use grating can freely roll, and effectively can improve screening effeciency.
Description
Technical field
The utility model relates to a kind of fish sieve of variable format.
Background technology
In fry rearing and adult fish culture process, according to the difference of manufacturing requirements and the market demand, fish need be periodically utilized to sieve the colony dividing size specification of hanking relatively consistent the fish that a large amount of specification mixes.The fry that such as length is less than 10 centimetres possesses and kills and devour habit mutually, and individual difference can cause killing and devouring increasing the weight of; And the relatively consistent fish of size specification can accurately be fed, growth is better, and survival rate is high, and bait conversion ratio is high.
There is the problem of following three aspects in the fish sieve of existing use: the aperture specification of (1) current fish mostly sieve is fixing, can only filter out the fish of a certain specification.But, owing to wanting the fish specification of screening not exclusively the same at every turn, such as, sometimes need the fry screening about 4cm, sometimes need the fry screening about 8cm, sometimes need the fry screening about 12cm.Therefore, the fish sieve making different pore size specification according to different demand is needed.Such fisherman needs the fish sieve preparing plurality of specifications, causes the wasting of resources, adds fisherman's cost.(2) current fish sieve mainly contains fish sieve and the metal fish sieve of bamboo wood braiding, and these two kinds of fish sieves all exist obvious shortcoming.Bamboo wood braiding fish sieve easily brittle, flexural capacity is poor, be difficult to after fractureing repair, and grating is coarse easily hinders fish, hand woven causes sieve mesh error large, and fry screening is uneven, and production efficiency is low.And metal fish sieve, it is often welded by bonding jumper, although specification standards and firm, weight is large, price is high, easily heavy water, easily get rusty.(3) when not easily changing when damaging appears in the grating of fish sieve, use is delayed.Therefore, urgently innovate fish sieve manufacturing technology, avoid making the fish sieve of different pore size specification and the wasting of resources that brings.
Utility model content
The purpose of this utility model is that the fish providing a kind of variable format is sieved, and can arrange the quantity of grating and the size of adjustable fish mesh size as required, thus the fish of screening different size; And can not fish be injured in screening process.
Solve the problems of the technologies described above, the utility model takes following technical scheme to be achieved:
A kind of fish sieve of variable format, comprise hollow cylinder, the bottom of described cylindrical shell one sidewall have be in same level and pitch of holes equal one row side opening, the bottom of described another sidewall of cylindrical shell has arranges the corresponding exhausting hole in side opening position with described one, horizontal plane residing for through hole higher than side opening residing for horizontal plane, between corresponding side opening and through hole, be interspersed with grating.
Described grating is the pole of smooth in appearance.The profile of described cylindrical shell is square body.
The line of described through hole and side opening and the angle of horizontal plane are 1 degree.
As the utility model embodiment, described each side opening be hole to inwardly, there is the blind hole of certain depth.Described grating to be punctured between described through hole and blind hole by through hole and to be trapped in through hole, and another sidewall of described cylindrical shell is hinged with one for the shrouding of through hole described in shutoff.
The both sides of described cylindrical shell are respectively equipped with handle.
Described cylindrical shell and grating are formed by lucite manufacture.
Compared with prior art, the utility model has following beneficial effect:
1) the utility model is by arranging the size of the quantity regulating fish mesh size of grating, thus the fish of screening different size, and sieve mesh specification standards, fry screening is evenly;
2) wherein grating is the perspex bar of round bar shape, and smooth surface can not hinder fish;
3) easily changing when damaging appears in grating;
4) the utility model in use grating can freely roll, effectively can improve screening effeciency.
Accompanying drawing explanation
Fig. 1 is schematic perspective view of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the A-A cutaway view in Fig. 2.
In figure: 1-cylindrical shell, 2-through hole, 3-blind hole, 4-grating, 5-shrouding, 6-handle.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is described in further detail.
As Fig. 1, a kind of fish sieve of variable format, comprise the cylindrical shell 1 that an inside is hollow, profile is square body, its specification size is 125cm × 52.5cm × 52.5cm, wall thickness is 2cm; The bottom of cylindrical shell one sidewall has 24 and is in same level and pitch of holes is the side opening 3 of 0.6cm, each side opening be hole to inwardly, there is the blind hole of certain depth, the diameter of blind hole is 1.2cm, the degree of depth is 1cm; The bottom of another sidewall of cylindrical shell has 24 through holes 2 higher than the elevation of water residing for side opening in the position corresponding with 24 side openings, the diameter of through hole is 1.2cm; Line between corresponding through hole and side opening and the angle of horizontal plane are 1 degree; 24 side openings and through hole one_to_one corresponding, grating 4 is interspersed with between the side opening and through hole of each group correspondence, wherein grating is smooth in appearance, diameter is the pole of 1cm, grating interts in cylindrical shell by through hole, be inserted in corresponding side opening, be hinged with a shrouding 5 for through hole described in shutoff at a sidewall bottom position of the cylindrical shell having through hole.Certain angle of inclination is arranged at the bottom that grating is formed, and be convenient to topple over the fish screened, the cylindrical shell in above-mentioned and grating are formed by lucite manufacture, and such grating is ganoid pole, in use can not hinder fish; The both sides of cylindrical shell are respectively equipped with handle 5, and user of service can hold handle and screen, easy to use.
The utility model is by arranging the size of the quantity regulating fish mesh size of grating, thus the fish of screening different size, and sieve mesh specification standards, fry screening is evenly; Adopt the mode of shrouding shutoff through hole to be fixed by grating, occur easily changing when damaging at grating.
Embodiment of the present utility model is not limited thereto; according to foregoing of the present utility model; according to ordinary technical knowledge and the customary means of this area; do not departing under the utility model basic fundamental thought prerequisite; to the amendment of other various ways that the utility model said structure is made, replacement or change, all drop within protection domain of the present utility model.
