The present invention relates to an opening and closing device for a greenhouse cover. The present invention is characterized in that an opening and closing device for a greenhouse cover, which opens and closes a cover (2) installed to keep a greenhouse (1) warm and to block the light, comprises a first roller unit (10) equipped to reel the cover (2) by rotating with a first driving unit (12) on one side of the greenhouse (1); a second roller unit (20) equipped to reel a band (12) connected to the end of the cover (2) by rotating with a second driving unit (22) on the other side of the greenhouse (1); and a control unit (30) equipped to open and close the cover (2) by controlling the operation of the first and second driving units (12, 22). Accordingly, the opening and closing device for a greenhouse cover according to the present invention has effects to prevent the bending and the damage to the greenhouse pipe due to the weight of the cover as the operation of opening and closing is operated while the end of the cover is transferred to one side of the greenhouse, and, in particular, to activate the photosynthesis of crops as the cover queues in the state of being reeled on the outside of the greenhouse when opening the cover, which prevents the sunlight shielding due to the cover, and enables to cover the plastic in an easier manner than the way that the cover queues on the ridge of the roof when exchanging the covered plastic. |
