Summary: | The utility model relates to a top push-pull full-open type windproof and snow-proof greenhouse. Wherein the two lower frameworks are oppositely and fixedly arranged in the length direction, the two rails are fixedly connected to the upper ends of the two lower frameworks respectively and extend in the length direction, the upper shed arch frames are arranged in the length direction, the two endsof each upper shed arch frame are connected with rolling mechanisms connected with the rails in a sliding mode, and every two adjacent upper shed arch frames are connected through a telescopic device.The plastic thin film covering the greenhouse keel frame is opened and closed through mutual cooperation of lead screw nut transmission and the connecting rod mechanism, the sealing performance and the heat preservation performance of a traditional greenhouse are reliably reserved, and meanwhile economic losses that the greenhouse film is damaged and the greenhouse frame is collapsed when encountering storm snow are avoid |
