AI Technical Summary
In the process of opening and covering existing greenhouse films, the top film and the side films are difficult to move synchronously, resulting in lag or displacement, which increases labor input and shortens the service life of the film.
The clamping device, consisting of an arc-shaped narrow plate and an arc-shaped cover, combined with adsorption holes and air extraction holes, uses adsorption magnets to achieve automatic clamping and synchronous pulling of the film. The design of the clamping groove and clamping protrusion ensures that the top and sides of the film move synchronously.
This technology enables the simultaneous opening and covering of greenhouse films, reducing additional preparation time, extending the lifespan of the films, and lowering labor input.

TECHNICAL FIELD
[0001] The utility model relates to agricultural planting equipment field, concretely is a kind of big -arch film uncovering, covering auxiliary device. BACKGROUND
[0002] In modern agricultural facilities, plastic film greenhouse is widely used in the planting of vegetables, flowers and economic crops due to its low cost, flexible construction, good heat and moisture retention effect and other advantages. As the core covering material, the daily management of the greenhouse film (such as ventilation, lighting regulation) needs to be frequently opened or closed.
[0003] In daily use, small and medium-sized greenhouses built manually account for a large proportion. When the film of such greenhouses is opened or covered, farmers usually need to pull the film on both sides of the greenhouse simultaneously. However, in actual application, due to the difference in film elasticity, the moving speed of the top film and the two side films is difficult to keep consistent, especially under the influence of wind or film aging, the top film is prone to lag or deviation, resulting in wrinkles and uneven stacking after opening, which requires farmers to spend additional time to pull and flatten the film, and the arrangement work takes more than half an hour, significantly increasing labor input. In addition, frequent arrangement can accelerate film wear and tear, shortening its service life. Therefore, there is an urgent need for an auxiliary device for manually opening and covering the greenhouse film, which can keep the film on both sides and the center of the greenhouse moving synchronously without subsequent tedious arrangement work.
