Problems solved by technology

In the above state, the damaged soft cover 2a has to be replaced with a new soft cover (frequent and recurring request to replace the existing soft cover 2a with a new soft cover)
[0012] And, since the winding motor M1 is arranged on one end of the winding rod 5, there is a difference in the rotational force between the winding motor M1 and the two ends of the winding rod 5.
Therefore, although one end of the winding rod 5 closer to the winding motor M1 rotates more smoothly, the other end

Abstract

An automatic fully-open roof system of a soft-covered multi-span greenhouse which automatically opens or closes the soft covers of each roof of the multi-span greenhouse while controlling the tensions of the support bands that hold the soft covers on the roof. The automatic fully-open roof system has a mounting block (100) to hold both the soft covers (2a) and the support bands (3) at the top of the roof (2); a winding rod (210) which holds a lower end of the soft cover to wind or unwind the soft cover, thus opening or closing the roof; a rod balancing means (300) for guiding the movement of the winding rod while maintaining the horizontality of tote winding rod; and band tension control means (400) for tightening or loosening the support bands, in response to a winding or unwinding operation of the winding rod, thus controlling the tensions of the support bands.

Description

technical field [0001] The present invention relates generally to soft-covered multi-span greenhouses, and more particularly to an automatic fully opening roof system for a soft-covered multi-span greenhouse that automatically opens or closes the soft-covered multi-span greenhouse's entire roof. cover while controlling the tension of the support bands that hold the soft cover on the roof. Background technique [0002] Generally, soft-cover greenhouses must allow users to freely control the temperature, humidity and lighting of the greenhouse, so as to obtain the best atmosphere in the greenhouse to effectively cultivate plants in the greenhouse, resulting in high-quality plants. [0003] figure 1 A conventional soft-cover greenhouse that has been preferably built on cultivated land in recent years is shown. As shown in the figure, the compartment of a conventional soft-cover greenhouse is equipped with: a plurality of arc-shaped frames 1 sequentially supported on the culti...
