Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, in particular to a greenhouse quilt rolling machine. Background Art

[0002] With the development of agricultural facilities, the application of greenhouse quilt rolling machines has become more and more popular, the scale of greenhouses has become larger and larger, and the length of quilts involved in greenhouse insulation, ventilation, and sunshade has become longer and longer. Taking the hanging rail greenhouse quilt rolling machine as an example, when the scale of the greenhouse is not large, the length of the quilt is generally about 100 meters, and only one reducer is needed, which is generally located at one end or the middle of the greenhouse. When the length of the greenhouse is large, it is necessary to use a reducer at both ends of the greenhouse at the same time when rolling the quilt. Due to the differences in the starting point and speed of the two reducers, the degree of winding of the quilt and the rolling tube, and the travel route of the rolling tube, the rolling tube driven by the two reducers will be out of sync. This asynchrony will cause the rolling tube to be damaged due to torsion, and will also affect the effect of rolling the quilt. Utility Model Content
