    Abstract:

    Based on the analysis of existing mechanical rolling shutter technology in solar greenhouse, the rear fixed type rolling shutter machine was selected as research object. The existing problems of the machine were analyzed and the solution was found, and the rear fixed type rolling shutter device in solar greenhouse was designed. The device was comprised of four parts of rope traction device, including coiling and uncoiling device, driving device and self-locking device. Besides, the layout scheme of rope traction device and movement mechanism of key devices were analyzed, which included coiling and uncoiling device and reducer. Finally, the designed rear fixed type rolling shutter device was proved, which indicated that it was better than the existed one by contrast experiment and the structure principle of rear fixed type rolling shutter device by test of physical model. According to the data of the test of physical model, the test errors and error source were analyzed. According to the comparison of physical model and actual production situation and calculation of the test data, the performance data of rear fixed type rolling shutter device was proved to be accorded with the performance requirements of the rolling shutter machine in the NY/T 2205—2012 technical specification for quality evaluation of greenhouse rolling shutter machine, which was issued by Ministry of Agriculture in China. The feasibility of the device was further validated. The design and experiment of rear fixed type rolling shutter device in solar greenhouse had improved the applicability of rear fixed type rolling shutter machine, provided technical support for its promotion within a larger scope, facilitated the production of planting crops in solar greenhouse and improved the production benefit.
