Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery and equipment, in particular to a shed frame limited self-propelled greenhouse curtain rolling machine. Background Art

[0002] Greenhouse rollers are agricultural machinery used to automatically roll up straw curtains in greenhouses. They are divided into front type and rear type according to the placement position, which are self-propelled greenhouse rollers on the greenhouse and fixed on the rear wall. Whether using a self-propelled greenhouse roller or a fixed on the rear wall, it can reduce the labor intensity of manually pulling straw thatch or insulation blankets, saving labor and effort. At the same time, by "uncovering early and covering late", it can increase the light time in the greenhouse, increase the greenhouse temperature, and facilitate vegetable production.

[0003] The technical solutions of the prior art and the existing products are basically to drive the shaft to rotate by the output speed torque of the motor, and then realize the up and down self-propelled process of the roller shutter machine through the layered rotation and superposition of the thermal insulation quilt.

[0004] The shortcomings of the existing technology are that the existing products all use a motor to drive the roller blind shaft, and the shaft rotates to achieve the retraction and release of the thermal insulation cotton. However, in this process, because the length of the rotating shaft is relatively long and the mass of the thermal insulation cotton is relatively large after being stacked layer by layer, it is easy for the torque at the far end and the near end of the shaft to be different, resulting in oblique rolling or uneven rolling and release. As the mass of the quilt continues to increase, this unbalanced force can easily lead to a sudden breakage of the roller blind shaft, resulting in a safety accident. Utility Model Content
