Description

Technical Field

[0001] This utility model relates to the field of greenhouse technology, and in particular to an electric greenhouse film winding device. Background Technology

[0002] The greenhouse of this technology mainly consists of a supporting arched frame 100 and a film module 200, with a winding shaft 300 on each side of the film module 200. To achieve ventilation and heat dissipation functions, one or both sides of the film module 200 need to be wound up. For large-scale greenhouse planting sites with dozens or even hundreds of greenhouses, manually opening and closing the film modules 200 is extremely inefficient and easily misses the optimal ventilation time. For example, winding up one film module 200 (i.e., opening ventilation) takes 1-2 minutes; opening dozens or hundreds of greenhouses one by one would take 1-2 hours, easily missing the optimal ventilation time.

[0003] Therefore, there is an urgent need to develop an electric greenhouse film winding device that is simple in structure and reliable in operation. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide an electric greenhouse film winding device. The technical solution adopted by this utility model is as follows:
