Sliding closure greenhouse and front sliding closure with double-track type anti-wind device

Abstract

Disclosed is a sliding closure greenhouse and front sliding closure with double-track type anti-wind device, which is characterized in that the device comprises an active sliding closure, a passive sliding closure, sliding tracks, anti-wind tracks, pulley supports and a movable pulley; above of the active sliding closure is provided with an active sliding cover frame, and two ends of top of the active sliding cover frame are provided with zonal anti-wind tracks; Two pulley supports are placed on the passive sliding closure, and the movable pulley is fixed between the two pulley supports through a hinge pin; The two pulley supports are each welded with the u-shaped anti-wind assemblies, and the tops of the openings of the u-shaped anti-wind assemblies are connected with the pulley supports, and the bottom of the openings of the u-shaped anti-wind assemblies are placed below the zonal anti-wind tracks; and the active sliding cover frame is provided with sliding tracks, and the movable pulley is mounted on the sliding tracks and matches with the sliding tracks. The device is effective in preventing the separation of the active sliding closure and the passive sliding closure and taking anti-wind function.

Description

technical field [0001] The invention belongs to a safety device for an agricultural machinery slide greenhouse, in particular to a double-track windproof device at the front of the slide cover of the slide greenhouse. Background technique [0002] The sliding cover greenhouse is a new product in the field of agricultural facility greenhouses. It has the intelligence of the thermal insulation multi-span greenhouse of the solar greenhouse. It slides on the arc-shaped track through a single-layer or multi-layer sliding cover to realize the function of heat preservation during the day and at night. . But in the windy day, the straw curtains and quilts of the existing solar greenhouse are often easily blown away by the strong wind, and the sliding cover of the sliding cover greenhouse is due to its large area and high altitude, and the passive sliding cover of the multi-layer sliding cover does not have steel ropes. There is a hidden danger of being blown down by the wind. Ther...
