摘　　要：基于现有日光温室卷帘的技术分析,选择后置固定式大棚卷帘机作为研究对象,针对其所存在的问题,寻求解决方案,设计改进型日光温室后置固定式卷帘装置,改进后的主体结构包括绳索牵引装置、收放线装置、驱动装置及传动自锁装置4部分。对其卷帘结构中绳索牵引装置的布置以及收放线装置和减速机等关键机构的运动机理做进一步分析,并将其与现有日光温室后置固定式卷帘机进行实体比例模型卷帘性能对比试验。在此基础上,针对该改进型卷帘装置进行了卷帘原理验证试验,对从实体比例模型上采集的数据进行数据分析与误差分析,并分析其数据误差来源,针对NY/T 2205—2012《大棚卷帘机质量评价技术规范》,进行实体比例模型和实际生产情况验证对比与推算,并由此推断出真实生产中该温室卷帘装置实际卷、放帘时间数据,验证了所设计的改进型日光温室后置固定式卷帘装置符合技术规范中的温室卷帘机卷、放帘时间性能指标要求,进一步验证了该卷帘装置的实施可行性。该改进型日光温室后置固定式卷帘装置的研究提高了后置固定式卷帘机的适用性,为其更大范围内的推广提供了技术支持,可为日光温室作物种植者提供更多的生产便利和提高生产效益。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.
