The original independent single-room mode is assembled together by scientific means, reasonable design and excellent materials. Its utilization rate is much higher than that of the traditional greenhouse, and the space is more reasonable and the operation is more convenient than the traditional greenhouse, which saves time and improves efficiency, and greatly meets the planting needs of people for out-of-season vegetables.
[0003] In the daily use of the existing double-opening film multi-span greenhouse with a shed roof, the existing multi-span greenhouse focuses on the heat preservation performance of the greenhouse, does not ensure that the influence of the airtightness on the greenhouse cultivation environment is minimized, the reserved ventilation openings are small, the internal and external environments of the multi-span greenhouse are in an isolated state, and the effect of natural leaching of rain and snow is extremely poor. Continuous cropping for a long time is likely to cause soil salinization, and the effects of ventilation, heat dissipation and dehumidification are average, which is likely to cause crop diseases and reduce production and income.
[0004] In the daily use of the existing double-opening film multi-span greenhouse with a shed roof, the structural strength of the existing multi-span greenhouse is also limited. When sudden ice, snow or freezing rain occurs in mountainous areas, it is easy to accumulate on the shed roof, causing damage or even collapse to the shed body, thereby damaging the vegetables in the shed.

[0013] The technical effects and advantages of the present utility model:
[0014] 1. By providing a film rolling lifter in the present utility model, the motor inside the film rolling machine case on the greenhouse roof provides power to the film rolling lifter, thereby driving the three-section telescopic column to rotate through the rotating bearing inside the film rolling lifter, and controlling the greenhouse film to close through the film rolling connecting collar connected to the three-section telescopic column. Thus, it is convenient for the operator to minimize the impact of long-term rainy and hot weather on the greenhouse cultivation environment, meet the growth needs of crops, open the skylight on the greenhouse roof during the idle period of the shed, and let rain and snow fall into the shed, which can play a role in natural salt washing and reduce the occurrence of pests and diseases.
