Abstract

The utility model provides a film preventing cultured crabs from escaping, which comprises a plastic film and a rope; and the rope goes through a film bag on one side of the plastic film. The film bag is heat-sealed or sewed with the plastic film, and of course, can be made by other processes which meet the use strength, e.g. bonding and the like. The rope can be made of all prior materials, and a nylon rope with low price and enough strength is preferred. When the film is used to culture the crabs, only a plurality of pegs need to be fixed around a culture site, and then the rope is fixed on the pegs, and the plastic film on the opposite side of the rope is buried into the soil and enclosed into a fence for preventing the cultured crabs from escaping. The rope is organically integrated with the film, so that the plastic film not only is convenient to dismantle and install, but also is not easy to damage, thereby prolonging the service life, reducing the production cost, and facilitating the environment.

Description

A kind of film that prevents that cultivated crabs from escaping

Technical field

The utility model relates to a kind of film that prevents that cultivated crabs from escaping, and belongs to the crab cultivation field.

Background technology

For famous-particular-excellent aquaculture technology, crab runs away and has certain rule.Grasp rule and take the corresponding precautionary measures, can control only cultivated crabs escape effectively.Be to prevent from that cultivated crabs from escaping to take height to build the method on the mud ridge eighties in last century, then generally mainly contains cement brick wall, calcium-plastic board fence, three kinds of forms of polythene net sheet fence the nineties.Above several forms are not that anti-to escape effect bad be exactly that anti-to escape the facility cost too high.In order to seek the effect of low-cost high-efficiency benefit better, the anti-escape plastic film of a kind of crab of special use has been adopted at vast crab cultivation family, thereby has lowered the crab cultivation cost effectively since entering 2,000 years.Concrete fence mode is: top and first surround shelf on every side with iron wire or nylon rope, and plastic film is wrapped on iron wire or the nylon rope then, reinforces one by one with staple again, adopts to have occurred following deficiency in such a way again:

1, installation labor hour consumption is big;

2, iron wire is hard, and film is soft, and iron wire is fixed with combining with staple of film, because of the breed of crab is to carry out outdoor, is difficult to guarantee that film is excellent;

3, on the cultural technique of juvenile crab, to change one basically every year and culture the place, the necessity of making use of momentum is like this dismantled the anti-escape plastic film of crab.Because iron wire and film combine, fix with staple, have strengthened and have dismantled artificial man-hour, are difficult to guarantee the perfect of its film especially, can only abandon the coming year and need not.

The utility model content

The utility model provides a kind of film that prevents that cultivated crabs from escaping, and comprises plastic film and rope, and rope passes the bag film of plastic film one side.Described bag film is made by plastic film heat-sealing or sewing, certainly, also can adopt other technologies that meet working strength, as bonding etc.Described rope can be known various material, preferred low price and the enough nylon ropes of intensity.

Described plastic film is for culturing the plastic film that crab is used, and has commercially availablely, is generally sealed polyethylene plastic.The thickness of preferably plastic film is 〉=25 μ m; 20 ℃ of tensile strength 〉=85Mpa; Tensile stretch 〉=150%.

When the utility model is used for crab cultivation, only need culturing the fixing many timbers of place periphery earlier, then rope described in the utility model is fixed on the timber, plastic film that will a relative side with rope is imbedded in the soil, surrounds to prevent that the fence that cultivated crabs is escaped from getting final product.Rope organically combines with plastic film, and not only demolition, installation convenience, and plastic film is difficult for being damaged, and prolongs its service life, reduce production costs, and favourable to environment.

Description of drawings

Fig. 1 is the utility model structural representation.

Embodiment

As shown in Figure 1, the utility model comprises plastic film 1 and rope 2, and rope 2 passes the bag film 3 of plastic film 1 one sides.Bag film 3 is made by plastic film 1 doubling post heat-seal.Plastic film 1 is a sealed polyethylene plastic, and thickness is 25 μ m, 20 ℃ of tensile strength 〉=85Mpa, tensile stretch 〉=150%.Rope 2 is a nylon rope.

Production of the present utility model can be adopted mechanical automatic job after the plastic film moulding, nylon rope and film are wrapped up automatically, adopts heat-sealing or sewing mode to make again, and production technology is simple.

Claims

1, a kind of film that prevents that cultivated crabs from escaping comprises plastic film and rope, it is characterized in that rope passes the bag film of plastic film one side.

2, the film that prevents that cultivated crabs from escaping as claimed in claim 1 is characterized in that described bag film is made by film doubling post heat-seal.

3, the film that prevents that cultivated crabs from escaping as claimed in claim 1, it is characterized in that sewing after described bag film is by the film doubling makes.

4, the film that prevents that cultivated crabs from escaping as claimed in claim 1 is characterized in that described rope is a nylon rope.

5, as each described film that prevents that cultivated crabs from escaping of claim 1-4, it is characterized in that described plastic film thickness is 〉=25 μ m; 20 ℃ of tensile strength 〉=85Mpa; Tensile stretch 〉=150%.

6, as each described film that prevents that cultivated crabs from escaping of claim 1-4, it is characterized in that described plastic film is a sealed polyethylene plastic.
