Description
Technical field
The utility model belongs to cultivation field, relates to a kind of cavity-separating crab pond culture device.
Background technology
Crab: the animal kingdom, Arthropoda, Crustachia, Decapoda, Reptantia.Crab is shellfish, and their health is protect by duricrust.Crab is by gill respiration.In biosystematics, the animal that crab is similar at last with shrimp, lobster, hermit crab.The crab of most kind lives in the sea or near ocean, also has the crab of some dwell in fresh water or stay in land.They are by female crab little crab in next life, and each female crab all can produce a lot of ovum, and quantity can reach more than millions of grain.Crab relies on earth's magnetic field to judge direction.The with a long history of crab eats in China, all on the books in " ease Zhou Shuwu can separate ", " all gift heavenly officials blister people ".Show in Venezuela in nineteen eighty-two with the film of crab name.
The process of growth of river crab is casted off a skin along with the young, young young crab or become spiral shell to cast off a skin and carry out, and the young often sloughs off a skin with regard to metamorphosis once, is also just divided into first phase.Cast off a skin from megalops larva and become the first phase young crab beginning, its body of shell of later often casting off a skin is long, and body weight all does once rapid increase, increases to the large crab of 250g from the body weight of every only large eye body 6-7mg gradually, at least need shell tens of time, and often to slough off a shell be all tiding over high point of once surviving.Need absorb large quantity of moisture during river crab shell, thus in shell process, quality obviously increases, in growth afterwards, losing of moisture is but slowly, and gradually by tissue growth is replaced, the speed of river crab growth is subject to the restriction of environmental condition, particularly water temperature and bait.If environmental condition is bad, degenerate cllipticity stops, and this is also the reason place that individuality of the same age, at different conditions build differ greatly.River crab growth and water body, the calcium in bait, phosphorus are in close relations.Related tests shows, the soft crab of firm shell, increases by 30%-40% before the non-shell of weight ratio, at most 1 hour during this period of time, few person's number minute, relies on the gill to absorb inorganic salts in a large amount of water and water.In natural pond or lake, soft crab 1-2 days shells are just hardening.If put into distilled water to raise soft crab, the ability that river crab absorbs calcium ion in water body is stronger than the ability absorbing calcium and phosphorus in manufactured feed.Must consider the ratio of calcium and phosphorus in the manufactured feed of dibastic sodium phosphate 2.5 kilograms (or quicklime or superphosphate) river crab, the disodium hydrogen ratio of calcium chloride and phosphorus is 2:1, the growth of guarantee river crab, the material demand of casting off a skin.
In molting process, need to clear up decortication timely, otherwise decortication Preserving time meeting polluted water in breeding box, under causing crab growing environment, grow bad.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provide a kind of cavity-separating crab pond culture device, the design of this cavity-separating crab pond culture apparatus structure is ingenious, cleaning is convenient, crab grows, solve existing crab cultivation device cleaning decortication inconvenient, structure such as to optimize not at the problem.
The purpose of this utility model realizes by following technical proposal: a kind of cavity-separating crab pond culture device, it is characterized in that: described cultivator comprises the breeding box be rectangle, described breeding box is divided into epicoele and cavity of resorption, in described epicoele, there is some dividing plates, described dividing plate makes described epicoele form cultivation chamber one, cultivation chamber two and cultivation chamber three, described cavity of resorption is connected with described epicoele and described epicoele bottom interior wall has the card edge of protrusion, described card is along being above placed with the breeding box be square, the bottom of described breeding box has the sewage draining exit that several are bar shaped, the pull bar erect and arrange also is fixed with bottom described breeding box, the lower end of described pull bar is fixed on described breeding box, the water surface is stretched out in the upper end of described pull bar, the two ends of described cavity of resorption are port, one end port of described cavity of resorption has pollution discharge mechanism, described pollution discharge mechanism comprises water pump, described water pump have water inlet pipe and outlet pipe, described outlet pipe one end is communicated with described water pump, the described outlet pipe other end is communicated with the water outlet block be square, on the port that described water outlet block is fixed on described cavity of resorption one end and sealing, the inner side of described water outlet block have several clean-out openings.
The roughly use procedure of this cultivator is as follows: this breeding box is divided into cultivation chamber one, cultivation chamber two and cultivation chamber three, raise the crab of different size respectively, prevent from little crab from being extruded lethal phenomenon by large crab to occur, breeding box put on i.e. observable crab size thus classification by pull bar, the feed do not eaten up and the excreta of crab fall in cavity of resorption by sewage draining exit, now start water pump, by the clean-out opening on water outlet block dirt washed away to other end port thus discharge breeding box, smart structural design, cleaning is convenient, this cultivator makes crab grow, lethality is low, cleaning dirt is convenient.
In above-mentioned a kind of cavity-separating crab pond culture device, the bottom of described pull bar is fixed with ringwise metal derby, has power supply in the upper end of described pull bar.
When needs lift breeding box; metal derby is energized; current value is very little; the contraction feeler that crab is slight can only be caused; owing to breeding box having multiple limbers, feeler may stretch in limbers by crab, if now pull-up breeding box can cause the feeler of crab to be fractureed; thus affecting the growth of crab, the setting of metal derby plays a protective role.
In above-mentioned a kind of cavity-separating crab pond culture device, the bottom of described breeding box is fixed with installing plate, and described water pump is fixed on described installing plate.
Installed water pump by installing plate, it is stable convenient to place.
In above-mentioned a kind of cavity-separating crab pond culture device, bottom described breeding box, side also has fixed head, described fixed head and installing plate have screwed hole.
By the screwed hole on fixed head and installing plate, pond bottom is fixed on to this device, fixation.
Compared with prior art, this cavity-separating crab pond culture device has the following advantages:
1, the design of this cavity-separating crab pond culture apparatus structure is ingenious, and cleaning is convenient, and crab grows.
2, this cavity-separating crab pond culture device is divided into cultivation chamber one, and cultivation chamber two and cultivation chamber three, raise the crab of different size respectively, prevent little crab from being extruded lethal phenomenon by large crab and occur.
3, the feed do not eaten up in this cavity-separating crab pond culture device and the excreta of crab fall in cavity of resorption by sewage draining exit, now start water pump, washed away dirt to other end port by the clean-out opening on water outlet block thus discharge breeding box, smart structural design, cleaning is convenient.
