The utility model relates to a simple method for building and covering the shade net of a vegetable steel frame greenhouse, including the method for constructing the vegetable steel frame greenhouse with a greenhouse film. The characteristics of the method are as follows: covering the coiled sunshade device above the greenhouse film on the top of the vegetable steel frame greenhouse; the coiled sunshade device includes a sunshade net, a film-pressing clip and a film-rolling device containing a film-rolling handle and a film-rolling scrol
1) When the length of the shading net is the actual length of the shading surface of the greenhouse, one side of the shading net is towed to the other side of the greenhouse along the roof film of the greenhouse with the help of ropes.
2) When the other side edge of the shading net intersects with the ground, the edge is fixed on the reel shaft matching the spreading length of the shading net by a pressure film clip, and the reel handle is installed at the end of the reel shaft of the reel. The reel handle is located at the intersection of the vegetable steel shelf and the end wall.
3) Continue to tow the greenhouse shade net along the top of the greenhouse to the other side of the greenhouse with the help of ropes. When the installed film coiler reaches the shoulder height of the greenhouse, remove the rope, fix the edge of the sunshade net on the other side of the reel shaft matching its length with the pressure film clip, and install the film coiler handle at the end of the reel shaft of the film coiler. The film coiler handle is located at the intersection of the vegetable steel shelf and the end wall.
4) Drive two end roll-up shafts by shaking two roll-up handles respectively. The roll-up shade net is retracted by the roll-up shafts at both ends of the shade net, so that the two rollers are located near the ridge of the greenhouse of vegetable steel frame, and then fix the shade net located in this area with the corresponding steel frame of the greenhouse ridge with the film-pressing rope.
