Problems solved by technology

Fix a cloth strip with a width of 5-8 cm in the north-south direction and 0.5-0.7 meters longer than the width of the shed film every 1.2 meters on the shed film. Swing achieves the purpose of dust removal. Although the dust removal rate in the middle part can reach 80%, the dust removal rate at both ends is less than 50%, and the average dust removal rate is 60%, and the dust removal is uneven. ; The theoretical shading rate is 4.6%-7.3% (the percentage of the device area to the lighting area of ​​the shed film)

Abstract

The invention relates to the technical field of greenhouses, in particular to a ceiling of a greenhouse. The ceiling comprises a first film and a second film. The second film is arranged above the first film. One end of the second film is connected with a fixed rod. The other end of the second film is connected with a movable rod. The height of the fixed rod is smaller than that of the movable rod. The two ends of the movable rod are connected with movable devices. The movable devices drive the movable rod to move between the movable rod and the fixed rod. The second film is arranged above the first film, the clean and light transmitting effect of the first film is kept, meanwhile, the second film is connected with the movable devices, the second film is convenient to assemble, disassemble and replace, and dust accumulated on the ceiling of the greenhouse is kept within the controllable range all the time.

Description

technical field [0001] The invention relates to the technical field of greenhouses, in particular to a roof of a greenhouse. Background technique [0002] At present, the greenhouse film dust removal method used by vegetable farmers in solar greenhouses is mainly cloth strip dust removal technology. Fix a cloth strip with a width of 5-8 cm in the north-south direction and 0.5-0.7 meters longer than the width of the shed film every 1.2 meters on the shed film. Swing achieves the purpose of dust removal. Although the dust removal rate in the middle part can reach 80%, the dust removal rate at both ends is less than 50%, and the average dust removal rate is 60%, and the dust removal is uneven. ; The higher theoretical shading rate is 4.6%-7.3% (the device area accounts for the percentage of the lighting area of ​​the shed film). Contents of the invention [0003] An object of the present invention is to provide a roof of a greenhouse, which can effectively remove dust from ...
