Abstract
The utility model discloses a film folding and unfolding device for a vegetable greenhouse. The film folding and unfolding device consists of a rocker, a handle, a universal joint, a reel and a plastic film, wherein one end of the plastic film is fixed on a fixing bar on the top of the greenhouse, and the other end of the plastic film is fixed on the reel; one end of the universal joint is connected to one side of the reel, and the other end of the universal joint is fixedly connected with the rocker; the handle is connected to the tail end of the rocker; the plastic film covers the surface of a greenhouse support by reeling of the reel. According to the film folding and unfolding device for the vegetable greenhouse, the vegetable greenhouse is protected from being attacked by strong wind, and losses caused by natural disasters are reduced. Moreover, the film folding and unfolding device for the vegetable greenhouse has the advantages of low manufacturing cost and convenience in installation.
Description
Technical field
The utility model relates to a kind of retractable apparatus, refers to especially a kind of green house of vegetables overlay film retractable apparatus.
Background technology
The outer surface of general green house of vegetables often adopts whole fixing covering of plastic film, and when there being strong wind interim, the resistance because film integral forms, often causes green house of vegetables to be blown down by strong wind, causes any property loss.
Utility model content
Problem to be solved in the utility model is the deficiency overcoming in background technology, and a kind of green house of vegetables overlay film retractable apparatus is provided, and this green house of vegetables overlay film retractable apparatus adopts the overlay film can folding and unfolding mode, has effectively protected green house of vegetables.
For addressing the above problem, the utility model is taked following technical scheme:
A kind of green house of vegetables overlay film retractable apparatus of the present utility model, by rocking bar, crank, universal joint, spool, plastic film, formed, one end of described plastic film is fixed on the fixed strip at booth top, the other end is fixed on spool, one end of described universal joint is connected to a side of spool, the other end is fixedly connected with rocking bar, and described crank is connected to the end of rocking bar.Described plastic film covers the surface of greenhouse bracket by the scrolling of spool.When strong wind comes temporarily, rotatable crank, drives spool to rotate by rocking bar, universal joint, if rotate to booth top, plastic film is wound on spool, can be by plastic film rolling to booth top; If rotate to booth two side bottoms, plastic film spreads out along booth surface, covers on the surface of greenhouse bracket.
A corrective measure of this programme is that plastic film is light-transmission type plastic film.
Take such scheme, have the following advantages:
By above scheme, can be found out, due to green house of vegetables overlay film retractable apparatus, by rocking bar, crank, universal joint, spool, plastic film, formed, one end of plastic film is fixed on the fixed strip at booth top, the other end is fixed on spool, one end of universal joint is connected to a side of spool, and the other end is fixedly connected with rocking bar, and crank is connected to the end of rocking bar.Therefore, a kind of green house of vegetables overlay film retractable apparatus of the present utility model, has protected green house of vegetables to exempt from strong wind and has attacked, and has reduced the loss that natural calamity causes, and also has in addition low cost of manufacture, advantage easy for installation.
