    摘要:

    基于現(xiàn)有日光溫室卷簾的技術(shù)分析,選擇后置固定式大棚卷簾機(jī)作為研究對象,針對其所存在的問題,尋求解決方案,設(shè)計改進(jìn)型日光溫室后置固定式卷簾裝置,改進(jìn)后的主體結(jié)構(gòu)包括繩索牽引裝置、收放線裝置、驅(qū)動裝置及傳動自鎖裝置4部分。對其卷簾結(jié)構(gòu)中繩索牽引裝置的布置以及收放線裝置和減速機(jī)等關(guān)鍵機(jī)構(gòu)的運(yùn)動機(jī)理做進(jìn)一步分析,并將其與現(xiàn)有日光溫室后置固定式卷簾機(jī)進(jìn)行實體比例模型卷簾性能對比試驗。在此基礎(chǔ)上,針對該改進(jìn)型卷簾裝置進(jìn)行了卷簾原理驗證試驗,對從實體比例模型上采集的數(shù)據(jù)進(jìn)行數(shù)據(jù)分析與誤差分析,并分析其數(shù)據(jù)誤差來源,針對NY/T 2205—2012 《大棚卷簾機(jī)質(zhì)量評價技術(shù)規(guī)范》,進(jìn)行實體比例模型和實際生產(chǎn)情況驗證對比與推算,并由此推斷出真實生產(chǎn)中該溫室卷簾裝置實際卷、放簾時間數(shù)據(jù),驗證了所設(shè)計的改進(jìn)型日光溫室后置固定式卷簾裝置符合技術(shù)規(guī)范中的溫室卷簾機(jī)卷、放簾時間性能指標(biāo)要求,進(jìn)一步驗證了該卷簾裝置的實施可行性。該改進(jìn)型日光溫室后置固定式卷簾裝置的研究提高了后置固定式卷簾機(jī)的適用性,為其更大范圍內(nèi)的推廣提供了技術(shù)支持,可為日光溫室作物種植者提供更多的生產(chǎn)便利和提高生產(chǎn)效益。

    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.
