Abstract

The utility model discloses a plastic tunnel film which comprises a plastic film 1 and is characterized in that the plastic film 1 has two layers, and air can be filled between the layers; the two layers of the film at a border 2 around the plastic film 1 with two layers is sealed in thermal welding to ensure that after the air is filled and an air charging port is sealed, the air can not leak, circular ring-shaped holes 5 used for penetrating and fixing a rope 4 are arranged at the border 2 around the plastic film 1, and the border 2 has at least two; after the space between the plastic film with double layer is filled with air, the light receiving effect is not influenced, and good thermal insulation action is also provided; when used, the utility model can be only covered on the plastic tunnel on time, the crop output is enhanced, and the production efficiency is also enhanced.

Description

The expandable plastic greenhouse film

The utility model relates to the transparent heat-insulated plastic film of using on the shade, particularly agricultural booth of usefulness such as a kind of greenhouse.

In order to produce agricultural product such as vegetables wide in variety, fruit in the winter time, satisfy the people's life requirement, people have invented big fluffy chamber planting technology.But existing big fluffy used insulation material all is the employing single layer plastics films, and the heat-insulating property of this single layer plastics films is very poor, and the temperature in the booth is scattered and disappeared easily, and especially night more very.Therefore, this booth can not form and keep " weather conditions " of a suitable plant growth effectively, promptly enables to cultivate corresponding crops, and its output also is difficult to satisfactory.In order to change this shortcoming, the peasant often every night lid layer insulation material on booth, and the sun removes insulation material after coming out again by day, to accept sunlight.But complicated operation needs great amount of manpower like this, if implant mass, the required number of only this item is just very considerable.

The purpose of this utility model is exactly to provide a kind of booth plastics in order to overcome the above problems, and makes booth can fully accept sunlight by day and at dissipated heat not in night, thereby realizes good heat insulation effect and don't the extra heat-insulation layer of needs.

The utility model realizes that the scheme of above-mentioned purpose is: a kind of plastic greenhouse film, comprise plastic film 1, and it is characterized in that: described plastic film 1 is for double-deck, and interlayer can charge into air; , do not reveal two membranes thermal weld involution at 2 places, edge of described double-plastic 1 with air after guaranteeing to charge into air and seal inflation inlet; At least two edges of 2 also are provided with and are used to penetrate the fixedly hole 5 of the rope 4 of usefulness in the edge, and the cross sectional shape in hole 5 roughly is annular.

Owing to adopted above scheme, can charge into air in the middle of the double-layer plastic, neither influence is subjected to light effect can play insulation effect preferably again.Because can penetrate rope 4 in preformed hole 5 fixes it, even also be easy to fix after the inflation.The peasant only needs disposable covering on the greenhouse frame in use, does not need nursing every day basically, gets final product even need nursing also only to need to charge and discharge gas every day, and operation is very easy.Can improve crop yield like this can enhance productivity again.

Fig. 2 is the utility model embodiment one front view.

Fig. 3 is the schematic diagram of a part of a kind of user mode vertical view of the utility model greenhouse film.

Fig. 4 is a kind of user mode front view of the utility model greenhouse film.

Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.

Embodiment one: see Fig. 1, be depicted as a kind of plastic greenhouse film, comprise plastic film 1, it is characterized in that: described plastic film 1 is for double-deck, and interlayer can charge into air; , do not reveal two membranes thermal weld involution at 2 places, edge of described double-plastic 1 with air after guaranteeing to charge into air and seal inflation inlet; 2 two edges also are provided with and are used to penetrate the fixedly hole 5 of the rope 4 of usefulness in the edge, and the cross sectional shape in hole 5 roughly is annular, because annular wire rope handling is relatively easy.

Convenient in order to fill, to exit, a limit in the involution edge 2 is provided with suction nozzle 3 all around.The suction nozzle 3 of this standard is sealed up after inflation is finished easily, and the method for envelope can be this mouth to be rolled then clamp with clip, and this mouth-sealing method all is good to filling, exitting conveniently.If but do not establish suction nozzle, and only need during use on an involution limit 2, to open an osculum, charge to seal up again behind the gas and get final product.Bother a bit but make so a little.

Reveal for greenhouse film is unlikely after inflation because of distortion makes the heating installation in the plastic greenhouse, can make wide and following slightly one deck of top one deck of bilayer film narrow slightly during design.When unaerated, above one deck lax; It is then indeformable substantially that then top one deck keeps suitably heaving lower floor after the inflation, thereby guarantee that film and frame are adjacent to.

Fig. 3 is a kind of user mode schematic diagram of the utility model greenhouse film.As seen from the figure, during use, only need double-plastic is covered on greenhouse frame 6, get final product with rope 4 fixing back inflations.In case of necessity, can bleed off gas daytime, to expose to sunlight better.

Double-layer plastic booth disclosed in the utility model can be widely used in farm, vegetable garden, orchard, forest farm and flower nursery etc., has great practical value.

Claims

1. a plastic greenhouse film comprises plastic film (1), it is characterized in that: described plastic film (1) is for double-deck, and interlayer can charge into air; Locate two membranes thermal weld involution in the edge (2) of described double-plastic (1), air is not revealed after charging into air and seal inflation inlet with assurance; At least two edges of (2) also are provided with and are used to penetrate the fixedly hole (5) of the rope of usefulness (4) in the edge, and the cross sectional shape of hole (5) roughly is annular.

2. plastic greenhouse film as claimed in claim 1 is characterized in that: in the involution edge (2) is provided with suction nozzle (3) or air inlet openings all around, and opening part can be rolled and clamp, so that the inflation back stops leaks.

3. plastic greenhouse film as claimed in claim 1 or 2 is characterized in that: the width of the two layers of plastic thin films (1) in the big fluffy film of described plastics is inequality, up big and down small.
