Abstract
The utility model relates to the aquaculture technology field, and provides a six-ring suspension cage for river crab cultivation. A framework of the suspension cage is formed by connecting six circular rings with an identical diameter in a surrounding manner, wherein the six circular rings are respectively used as an upper surface, a lower surface, a front surface, a rear surface, a left surface and a right surface. External sides of the circular rings as the front, rear, left, right and lower surfaces are wrapped with net sheets, which are stitched on the circular rings. The circular ring as the upper surface is stitched and connected with the large-diameter end of a variable-diameter net cylinder which is made of net sheets. The small-diameter end of the variable-diameter net cylinder is equipped with a plastic circular cylinder. Simple in structure, low in manufacture cost and good in firmness and durability, the six-ring suspension cage of the utility model occupies large space of waters, substantially without large blind angles in the cage body, and has no influence on the original breeding yield of waters, when suspended in waters.
Description
Technical field:
The utility model relates to technical field of aquaculture, is specifically related to the six ring cages that a kind of cultivating river crab is used.
Background technology:
Eriocheir sinensia is commonly called as river crab, is the distinctive famous-brand and high-quality aquatic products of China, mainly is distributed in China the Changjiang river, the Liaohe River, the Oujiang River, wherein so that the Changjiang river water system river crab growth is fast, specification is big, resistance against diseases is strong, delicious flavour and famous.
The Changjiang river water system Eriocheir sinensia is the important breed objects in area such as the middle and lower reach of Yangtze River, and it cultures historical existing two more than ten years.Through the development of more than two decades, the culture of Chinese mitten crab industry has become the industry that China shows unique characteristics at present, and national culture of Chinese mitten crab output was above 350,000 tons in 2005.Particularly along with the structural readjustment of rural industry, large quantities of farmlands turn to cultivating river crab, we can say that culture of Chinese mitten crab had become the major industry of the current structural readjustment of rural industry, increasing peasant income already.
Along with the develop rapidly of culture of Chinese mitten crab industry, some problems anxious to be solved have also appearred, as germplasm mix, environmental deterioration, disease take place frequently.
The utility model content:
The six ring cages that the utility model technical problem to be solved is to provide a kind of cage cultivating river crab to use.
The utility model technical problem to be solved adopts following technical scheme to realize,
The six ring cages that a kind of cultivating river crab is used; It is characterized in that: the cage skeleton by six isodiametric annulus respectively as about, six faces in all around interconnect and surround; The annulus outside on said all around, following five faces is enclosed with the net sheet; The net sheet is sewn on the annulus, and said top annulus is sewed up with the reducing net tube larger diameter end of processing with the net sheet and is connected, and the smaller diameter end of said reducing net tube is provided with plastic cylinder.
Said annulus adopts iron wire or steel wire to process, and the contact point between annulus joint and annulus and the annulus is pricked dead with thin wire or welded together.
Said net sheet adopts 22 order net sheets, and net sheet and annulus contact position are sewed up with 3 * 2 formal wires.
The utility model is simple in structure, cost is low, and it is big that the cage of six ring structures takies the water body space, sturdy and durable, does not have big dead angle in the cage body basically, and cage is hung in the water, does not influence the cultured output in original waters.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with specific embodiment and diagram, further set forth the utility model.
As shown in Figure 1; The six ring cages that a kind of cultivating river crab is used; Cage skeleton 3 by six isodiametric annulus respectively as about, six faces in all around interconnect and surround, the annulus outside on all around, following five faces is enclosed with the net sheet, the net sheet is sewn on the annulus; Top annulus is sewed up with reducing net tube 2 larger diameter end of processing with the net sheet and is connected, and the smaller diameter end of reducing net tube 2 is provided with plastic cylinder 1.
Annulus adopts iron wire or steel wire to process, and the contact point between annulus joint and annulus and the annulus is pricked dead with thin wire or welded together.The net sheet adopts 22 order net sheets, and net sheet and annulus contact position are sewed up with 3 * 2 formal wires.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
