The present invention relates to a greenhouse roof insect-proof and light-proof screen structure and, more specifically, to a greenhouse roof insect-proof and light-proof screen structure having an insect-proof net and a light-proof screen which can be automatically operated to be reversedly opened/closed with respect to each other. When a light-proof screen is opened in a conventional greenhouse roof light-proof screen structure, external insects invade a greenhouse and affect crops, so an insect-proof net needs to be installed. However, when means for controlling the opening and closing of an insect-proof net are formed other than a light-proof screen in a greenhouse, the structure of the greenhouse may be very complicated. To this end, according to the present invention, an insect-proof net and a light-proof screen are formed on a greenhouse roof part to be opened or closed by being connectively operated with respect to each other. The insect-proof net is spread when the light-proof screen is folded, and the light-proof screen is folded when the insect-proof net is spread. The operation of an insect-proof net or a light-proof screen can be automatically controlled and managed even through only one control. |
