1、 果蔬大棚电动卷帘机果蔬大棚电动卷帘机 摘摘 要要 果蔬大棚卷帘机是今后大棚种植必需的机械装备和发展方向， 它改变了传统人 工卷帘操作的方法，比人工操作提高效率十几倍以上，解决了每天卷放草帘的劳动 强度，改善了严冬露天操作的环境，重要的是缩短了卷、放草帘所消耗的时间,延 长了光照时间.大大提高了劳动效率和经济效益. 现今市场上主要供应的是一种是走动式卷帘机这种卷帘机利用卷帘机的动力上 下自由卷放草帘子，不必受大棚坡度大小的限制。但这种卷帘机结构复杂，稳定性 差，寿命低，且不适合长度过大的大棚。 本课题所设计的是一种固定式卷帘机， 它模拟人工操作,通过缠绕在绳上的绳子 的拉紧和放松,实现草帘的卷

2、收和铺放。 其主要机构包括电动机、减速机、卷帘装置等。本课题着重对卷帘机的减速机 及卷帘装置进行设计，使其在压低成本的前提下满足普通斜坡式大棚的要求。 关键词：卷帘机，减速机，传动比，抗弯强度 FRUITS AND VEGETABLES BIG AWNING ELECTRICALLY OPERATED VOLUME CURTAIN MACHINE Abstract：The fruits and vegetables big awning volume curtain machine will be the next big awning planter essential machinery

3、equipment and the development direction, it changed the traditional artificial volume curtain operation method, will enhance above efficiency several times compared to the manual control, solved the daily volume to graze animals the curtain the labor intensity, improved the severe winter open-air op

4、eration environment, more importantly reduced the volume, has grazed animals the time which the curtain consumed,Lengthened the illumination time.Enhanced the labor efficiency and the economic efficiency greatly. Nowadays in the market the main supply is one kind is takes a walk about the type volum

5、e curtain machine this kind of volume curtain machine use volume curtain machine power the free volume to graze animals the curtain screen, does not need to receive the big awning slope size the limit. But this kind of volume curtain machine structure is complex, the stability is bad, the life is lo

6、w, also does not suit the length oversized big awning. What this topic designs is one kind of stationary volume curtain machine, it simulates the manual control,Through winding on rope string tautness and relaxation,The realization grass curtain volume receives and sets. Its main organization including electric motor, speed reducer, volume curtain installment and so on. This topic emphatically carries on the design to the volume curtain machine speed reducer and the volume curtain instal
