Abstract
The utility model provides an automatic prismoid fish standard grading device which comprises a fish guiding passage made of fish nets and grids connected with the passage. The utility model is characterized in that the grids are prismoid grids. Included angles between the inclined planes of the prismoid grids and horizontal planes are between 40 to 50 DEG so as to cause the grading of the fish standard to be more smooth, rapid and convenient, and the best angle is 45 DEG. In order to fit into the grading of different fish standard, four inclined planes and the bottom plane of the prismoid grids can be disassembled entirely so as to select appropriate grids; in order to avoid being injured fish bodies during grading, the prismoid grids are formed by weaving a plurality of circular pipes threaded by two strips, and the circular pipes can rotate. When the utility model is used, people can conveniently carry out the standard grading to stock of fish in water or on the coast, labor intensity of the people can be lightened, and the damage or the death of the fish bodies can be avoided.
Description
Technical field
The utility model relates to the fish specification grading plant of culture fishery, the automatic grading plant of particularly a kind of prismoid fish specification.
Background technology
The particularly large-scale cage culture of fish culture, even throw in a collection of fry, after the certain hour breed, with the fish in a bite net cage, the individual difference great disparity, at this moment the shoal of fish in the net cage should be carried out classification by specification limit, the fish that specification is close focuses in the same net cage to be cultured, to improve the culturing economic benefit.On the other hand, culturing the finished product fish also needs fish is carried out classification at before sales, allows the fish list marketing that reaches specification requirement, and the fish that does not reach specification is proceeded to culture.
The stage division of cultured fishes may be summarized to be in the water classification and fishes for two kinds of back disembarkation classifications.China does not have fish specification classifying equipoment on the bank at present, in the water classification except that artificial fry breeds (using classifying screen), or not classifications in the whole culture-cycle, or rely on manually-operated to carry out classification.The former has directly influenced culture efficiency; Latter's labour intensity is big, and the shoal of fish to be in time of high-density state long, cause fish body damage or dead easily.In recent years, the domestic development " flexible purse seine formula separate gate device " and " cage type rigidity separate gate device " carry out classification to the fish of cage culture.But there is big difficulty in the marine practical operation of two kinds of structures, and separating effect is also unstable.
Summary of the invention
The purpose of this utility model is to provide a kind of prismoid fish specification automatic grading plant, and it can be convenient for people in water or on the coast the shoal of fish be carried out the specification classification, has both alleviated people's labour intensity, avoids the damage or the death of fish body again.
The automatic grading plant of prismoid fish specification described in the utility model, it comprises that fishnet makes leads fish passage and coupled grid, and it is characterized in that: described grid is the prismoid grid.
For the classification that makes the fish specification is more smooth and easy quick, the inclined-plane of described prismoid grid and the angle of horizontal plane are between the 40-50 degree, and best angle is 45 degree.
In order to be fit to the classification of different fish specification, four inclined-planes and the bottom surface of described prismoid grid are all detachable, so that select suitable grid.
Injured when the classification for fear of the fish body, described prismoid grid is worked out by some pipes that pass through two ropes, and pipe is rotatable.
The beneficial effects of the utility model are, can make the movable rack of different spacing according to breed variety and hierarchical objectives, as long as change movable rack, just can carry out the fish graded operation of different cultivars, different size; In water, can keep movable rack and current to be best angle automatically, can use and drive, guarantee separating effect as instruments such as acoustic signal device; The pipe of grid can rotate, and reduces the injured risk of fish body in the classification process; Simple to operate, easy to maintenance.
Description of drawings
Fig. 1 is the utility model schematic diagram.
Fig. 2 is a prismoid grid schematic diagram of the present utility model.
Fig. 3 is the schematic diagram on an inclined-plane of the utility model prismoid grid.
Among the figure: 1. fishnet is made leads the fish passage, 2. prismoid grid, and 3. terrace with edge framework, 4. each trifle is all passed same engineering plastics pipe by two ropes.
The specific embodiment
The automatic grading plant of prismoid fish specification described in the utility model as Fig. 1, Fig. 2 and shown in Figure 3, below the fish passage of being made by fishnet 1, connects a prismoid grid 2, and terrace with edge framework 3 is made by rigid material, and the angle of itself and horizontal plane is 45 degree.Show that according to experiment each side of terrace with edge becomes miter angle with water (flow) direction, the most suitable fish passes from grid.Four inclined-planes and a bottom surface of prismoid grid are all detachable, can make the required automatic grading plant of prismoid fish specification according to the density difference of grid like this.Grid can use stainless steel tube or engineering plastics pipe directly to be assemblied on the terrace with edge framework.But preferably use the grid of being worked out with netting twine and engineering plastics pipe by fishing, in order to make fixed interval wherein, each joint all passes same engineering plastics pipe 4 by two ropes, be compiled into grid again, like this, the pipe of grid can rotate, and is injured in the time of can avoiding the fish body to pass.In fish specification classification process, promote the automatic grading plant of fish specification (in the net that should note not making fish be wrapping to the fish passage) gradually, increase the school density in the automatic grading plant of fish specification, make the following fish of goal standard all pass grid.
Claims (4)
