The present invention relates to an apparatus for opening/closing ventilation windows of a plastic greenhouse, and a plastic greenhouse ventilation system using the same. The purpose of the present invention is to provide an apparatus for opening/closing ventilation windows of a plastic greenhouse, which is able to (semi)automatically control the opening/closing of ventilation windows of a plastic greenhouse, to conveniently circulate air in the plastic greenhouse, and to fundamentally prevent the conventional ventilation window damage due to the external environment, and a plastic greenhouse ventilation system using the same. The apparatus for opening/closing ventilation windows of a plastic greenhouse according to the present invention is an apparatus installed to open/close a predetermined area of a plastic greenhouse for air circulation, and comprises a pinion capable of rotation and reverse rotation; an operator for controlling the rotation and reverse rotation of the pinion; a first rack having linear motion to the left direction (or the right direction) in gear with saw tooth of the pinion in rotation (or reverse rotation) of the pinion; and a first vertical load opening (or closing) the ventilation windows by pushing up (or pulling down) the ventilation windows with the rotatory power generated in connection with the left direction (the right direction) linear motion of the first rack. |
