The greenhouse gardening of north vegetables has now obtained large-area popularization, for winter warming, on booth, need to cover one deck straw screen or mat; Straw screen or mat is put down when cold at night, straw screen or mat is rolled during solar irradiation by day, hocket every day.Sometimes meet the unexpected variation of weather, also need to cover at any time; Put by manually rolling up fully, not only time-consuming taking a lot of work also increased labourer's labour intensity.

The utility model content:

The utility model is exactly at the problems referred to above, and a kind of booth automatic curtain device that can respond to illumination and air humidity is provided.

For achieving the above object, the utility model adopts following technical scheme, the utility model comprises greenhouse bracket, its structural feature is provided with motor above support, the output shaft of motor links to each other with an end of curtain rolling shaft, the other end of curtain rolling shaft is positioned at the retainer ring that is fixed on the support, is provided with light sensor, moisture sensor above support; Top, bottom at support are respectively arranged with upper limit position switch, lower position switch; Motor, light sensor, moisture sensor, upper limit position switch and lower position switch link to each other with the control circuit box by lead respectively, are provided with the sill with upper limit position switch, the corresponding roller shutter of lower position switch in the lower end of roller shutter.

The beneficial effects of the utility model:

Owing to above support of the present utility model, be provided with light sensor, but just make the utility model perception night and daytime, and automatically roller shutter is rolled or put down; Owing to above support of the present utility model, be provided with moisture sensor, the utility model can be detected constantly to air humidity, when rainy, automatically roller shutter is put down, when it is fine, automatically roller shutter is rolled; Can finish roller shutter work automatically, not only the time and labour saving has also reduced labourer's labour intensity.
