OPEN AND SHUT SYSTEM OF LAGGING COYER FOR A HOTHOUSE STATIONERY

摘要

The present invention relates to a switchgear for automatically opening and closing the thermal cover used in the greenhouse.;The present invention is equipped with a plurality of bobbins (3) on the rotating shaft (1) operated by the reduction motor (2) in order to open and close the thermal cover (6) in the greenhouse (H) to move the thermal cover (6) In the known opening and closing device in which a tugboat 5 is wound around each bobbin 3,;Auxiliary pivot shaft 4 is provided to flow outside of the pivot shaft 1, and a clutch member C is provided at the end of the auxiliary pivot shaft 4, thereby assisting the auxiliary pivot shaft 4 by the clutch member C. ) Is configured by the opening and closing device of the subsidiary cover for the greenhouse, characterized in that the device is configured to be rotated or rotated integrally with the rotating shaft (1), even when deformation such as bending or torsion in the rotating shaft Not only is it possible to cover all the covers in a uniform state, it is also an advantageous design to prevent the overloading by automatically stopping when all the covers are in place.
