Arched shed heat-insulating quilt full-shed surface winding and unwinding device and using method thereof

Abstract

The invention relates to an arched shed heat-insulating quilt full-shed surface winding and unwinding device and a using method thereof. The winding and unwinding device comprises an arched shed, a traction device, a rope system and a heat-insulating quilt. A driving screw rod and a driven screw rod in the traction device form a linkage relationship through a positive and negative rotating connecting rope which is arranged in the rope system, so that the winding and spreading work of the heat-insulating quilt can be completed by only configuring a motor; the device cost is reduced; a mounting process is simplified; the heat-insulating quilt can cross over the shed top and can be spread and wound on a full-shed surface under the driving of the winding and unwinding device; meanwhile, the heat-insulating quilt can be collected and placed on the ground by the device, and a large amount of shade in the shed caused by placing the heat-insulating quilt on the top of the arched shed can be avoided; the reduction of photosynthesis of plants caused by shading and the influence on the yield can be prevented.

Description

technical field [0001] The invention belongs to the technical field of solar greenhouse environment control, and in particular relates to a large-volume arch shed thermal insulation quilt rolling device for the entire shed surface and a use method thereof. Background technique [0002] Since the 1980s, solar greenhouses have entered a stage of large-scale development. So far, a series of energy-saving solar greenhouses have emerged, which have made great progress and improvement in terms of structural performance and supporting facilities. [0003] However, due to the low land utilization rate of the solar greenhouse itself, in order to conform to the trend of mechanization and large-scale production, in recent years, farmers have spontaneously built large-volume arches in the north-south direction in Shenxian County and Shouguang in Shandong, and Huludao in Liaoning. shaped greenhouse. This kind of greenhouse has the advantages of improving land utilization, productivity, ...

AI Technical Summary

Problems solved by technology

[0009] The above-mentioned thermal insulation quilt roll-up devices all have the following disadvantages. The thermal insulation quilt is placed on the roof; the thermal insulation quilt will block the sunlight entering the greenhouse during the day, forming a wide shadow zone inside the greenhouse, thereby affecting the photosynthesis of crops and soil. Heat accumulation, which in turn affects the growth of crops during the day and the increase of greenhouse temperature at night
