Abstract
The utility model relates to a device for culturing prawn, mainly composed of a reflecting net, a palpus inverting net and a feeding ring. The palpus inverting net is supported by two fixed rings, the reflecting net is connected to the palpus inverting net, and the feeding ring is connected to the fixed ring of the palpus inverting net. The utility model can ensure shrimps flow into the feeding ring through the palpus inverting net in single direction for integrated feeding and shrimp disease cure. The utility model which has simple structure and low cost is a special tool for culturing prawn.
Description
The utility model relates to a kind of aquaculture special implement, particularly a kind of prawn culturing device.
At present, in this field of prawn culturing, generally do not use as yet and culture utensil.The utility model patent of patent No. ZL93202644.3 discloses a kind of cultured prawn bait groove, and its primary structure is a framework that groove is arranged, and the side of groove is the venetian blind type screen that is connected between framework.Its main purpose is to be convenient to drop into bait, can prevent effectively that bait is scattered with current, understands the consumption of bait at any time, so that replenish bait.But there is complex structure in this bait groove, can not solve diseases prevention in the prawn culturing process, problem such as antifouling.
The purpose of this utility model just is at the deficiencies in the prior art part, and a kind of prawn culturing device is provided, and both can feed conveniently, can solve diseases prevention, problem such as antifouling again.
The purpose of this utility model is achieved through the following technical solutions.This prawn culturing device by reflect net, falling must net and feed circle and constitute.Fall and to support by two retainer plates by net, reflect net and be connected down palpus on the net, feed circle and be connected down on the retainer plate that must net.
Described palpus net comprise outer layer net and inner layer net.Two retainer plates that support outer layer net are isodiametric ring.Inner layer net is positioned at the outer layer net wire side, and its end is connected on the retainer plate, and the other end is supported by annular ring.This annular ring is connected on another retainer plate by backguy, forms tapered channel.
Above-mentioned nursing circle is oval reticulate body, is feeding the dead lever that support is arranged on the circle and fix this reticulate body.The opening that interlinks with the tapered channel that falls in must netting is arranged on the nursing circle, but and the outlet of a free switch.
The utility model compared with prior art has following technique effect: 1. simple in structure, cost is low.2. use this cultivator, can concentrate nursing, can treat and prevent and treat prawn disease effectively; Can improve water quality, stop the pollution of water quality; Can also rationally use bait, medicine, aquaculture cost is reduced about 30%.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing in detail utility model is described in detail.
Described prawn culturing device by reflect net 1, falling must net 2 and feed circle 3 and constitute.Reflecting has the net of reflecting dead lever 4 on the net 1, can be fixed on any one position in the shrimp-cultivation pool reflecting net 1.Reflect net 1 and fall and to link together by net 2.Fall and to constitute by preceding retainer plate 5, back retainer plate 6, annular ring 7, backguy 8, outer layer net 9, inner layer net 10 and outer layer net support bar 13 by net 2.The circle that preceding retainer plate 5, back retainer plate 6 are made for hard materials such as bamboo wood or plastics.Outer layer net 9 is supported by preceding solid chamber circle 5, back retainer plate 6.It comprises two parts, and wherein a part is the tubular dictyosome between preceding retainer plate 5 and back retainer plate 6; Another part is the taper dictyosome on the retainer plate 5 before being connected in.Also have an inner layer net 10 in above-mentioned cylindrical body, these inner layer net 10 1 ends are connected on the retainer plate 5, and the other end is supported by annular ring 7, and annular ring 7 is connected on the retainer plate 6 of back by backguy 8.Annular ring 7 is littler than preceding retainer plate 5 diameters, and inner layer net 10 is supported for a platform shape dictyosome by preceding retainer plate 5 and annular ring 7.In inner layer net 10, just formed a tapered channel, adopted the dictyosome of above this structure, can guarantee that shoal of shrimps can not follow Yuan Lu and return.Feeding circle 3 be oval dictyosome, and this ellipse dictyosome is by feeding 11 supports of circle dead lever, and at the bottom of can being fixed in the pond by this dead lever.Feeding circle 3 has import, and this import is connected with back retainer plate 6, makes to feed circle 3 and be connected with the tapered channel of palpus net 2.Feed and to also have one to feed and iris out mouthfuls 12 on the circle 3, feed iris out have on mouthfuls 12 can free switch door.
During concrete the use, follow the pond habit according to shrimp, four jiaos of shrimp-cultivation pools, at the bottom of reflecting net dead lever 4, outer layer net support bar 13 and feeding circle dead lever 11 insertion shrimp-cultivation pool ponds, reflect net 1, falling must net 2 and feed circle 3 and be fixed under water, can surface above feeding circle 3, so that can drop into bait or middle cartridge bag.During nursing, the bait input can be fed in the circle 3, shoal of shrimps stopped in feeding circle 3 1-2 hour, can follow after having enough to feed and iris out mouthfuls 12 and swim out of.When shoal of shrimps is sick, can shut the door that nursing is irised out on the mouth 12, cartridge bag in the input, the concentrated treatment in nursing circle 3 waits shoal of shrimps to stop 1-2 after individual hour, opens and feeds the door of irising out on the mouth 12, and shoal of shrimps is promptly swum go back to the shrimp pond again.
