天津市农机鉴定推广站与天津南华成套工具公司共同研制了ORJ—80A型日光温室卷帘机(见图1)。该机采用了2K－H－D少齿差减速机构，因而提高了齿轮强度，增大了传动比，机构灵巧，生产工艺简单。该机只需6min即可卷铺面积为80m2～100m2的温室大棚草帘，不仅极大地降低了菜农的劳 Agricultural Machinery Identification Extension Station in Tianjin and Tianjin South China Tool Kit companies jointly developed the ORJ-80A sunlight greenhouse shutter machine (see Figure 1). The machine uses a 2K-H-D less tooth difference deceleration mechanism, thus increasing the gear strength, increased transmission ratio, the mechanism dexterity, the production process is simple. The machine only 6min can roll shop area of ​​80m2 ~ 100m2 greenhouse straw curtain, not only greatly reduced the workers of agricultural workers
