Abstract
The utility model discloses a vegetable greenhouse ventilation apparatus belonging to the ventilation device. Longitudinal paralleling strip films are arranged at the surface of the middle lower part of the shelf film and bundled up by the crossing-bundling rope, ventilation holes are positioned between the strip films, and the cover film is welded above the ventilation holes. Compared with the existing technologies, the utility model is characterized in that the design is reasonable, the structure is simple, processing is easy, application is convenient and the service life is long.
Description
Technical field
The utility model relates to a kind of ventilation unit, specifically a kind of green house of vegetables ventilation unit.
Background technology
At present, the ventilation unit that many green house of vegetables adopt is that the canopy body covers two films, and the middle part is overlapping, when needing to ventilate, normally lap is pushed aside, when not needing to ventilate, film is piled up again.Owing to be that the canopy body covers two films, add and often push aside that cause film fold to occur, film can not flatten with overlapping, forming the globule on the film influences the booth printing opacity.Canopy body film sealing simultaneously is not thorough, at the big bad weather of wind, also can tear canopy body film to shreds, causes the integral body of canopy body film to damage.
Summary of the invention
Technical assignment of the present utility model is at above weak point, and a kind of a kind of green house of vegetables ventilation unit simple in structure, reasonable in design is provided.
The technical scheme that its technical problem that solves the utility model adopts is: having the bar film of parallel longitudinal on the surface of canopy body film middle and lower part, by tie string is staggered the bar film is tied up, is air vent between the bar film, and the top of air vent is welded with epiphragma.
During use, epiphragma is rolled, exposed air vent; When not needing to ventilate, epiphragma is put down, edge and the canopy body film close with epiphragma bonds together then, can reach the purpose of sealing.Prevent that so not only canopy body film is destroyed under bad weather, and ventilation effect is good.
A kind of green house of vegetables ventilation unit of the present utility model is compared with prior art, have reasonable in design, simple in structure, be easy to characteristics such as processing, easy to use, long service life.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing 1 is the structural representation of green house of vegetables ventilation unit;
Accompanying drawing 2 is the end view of Fig. 1.
Embodiment
Explain below with reference to Figure of description a kind of green house of vegetables ventilation unit of the present utility model being done.
A kind of green house of vegetables ventilation unit of the present utility model has the bar film 5 of parallel longitudinal on the surface of canopy body film 1 middle and lower part, by tie string 3 is staggered bar film 5 tied up, and between the bar film 5 air vent 2, the top of air vent 2 is welded with epiphragma 4.
A kind of its processing and fabricating of green house of vegetables ventilation unit of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
