Working Principle

Roof Track-Cross Ventilation System

The gear motor, for the ventilation system, is installed on the skeleton of the greenhouse. The driving shaft of the gear motor is connected with transmission shaft by the welding joint, passing through the bearing plate that is fixed on the truss, able to revolve. The rack, connecting the driving rod by the rack-rod connector, is meshed with the pinion that is fixed on the truss. The driving rod drives a set of supporting arms that link the rod with tube-arm connector and that connect the window by window-hinging supporter. When the gear motor works to actuate the rack-pinion structure, the driving rod can control the switching actions of the roof windows.
