Winding device for greenhouse heat preservation quilt

Abstract

The invention discloses a winding device for a greenhouse heat preservation quilt. The winding device includes a greenhouse body, a driving motor, the heat preservation quilt, connecting rods, a powergenerator and electric pushing rods; the greenhouse body includes arc-shaped fixing frames, a winding box, a driving box, a controller and connection bases; a winding shaft penetrates through and extends into the winding box; the heat preservation quilt is arranged on the surface of the winding shaft, first solar photovoltaic plates are arranged in the middle of the top of the winding box, and the power generator includes a mounting plate; a retractable casing rod is movably connected to the surface of each connection base through a movable shaft, an angle sensor is arranged on one side of each retractable casing rod, the connecting rods are arranged at the ends, away from the connection bases, of the retractable casing rods, and the upper and lower ends of the heat preservation quilt areconnected with the winding shaft and the connecting rods respectively. The winding device has the advantages that vegetation absorbs the sunlight conveniently and the heat preservation quilt can be wound and replaced in time. The problem that heat preservation thin film of traditional greenhouses is inconvenient to replace and wind is solved.

Description

technical field [0001] The invention relates to the technical field of agricultural greenhouse equipment, in particular to a winding device for greenhouse thermal insulation quilts. Background technique [0002] With the production of high molecular polymers - polyvinyl chloride and polyethylene, plastic films are widely used in agriculture. In the early 1950s, Japan and European and American countries successfully applied greenhouse films to cover hotbeds, and then covered small sheds and greenhouses with good results. . With the development of production, the application of greenhouses has become more and more extensive. At present, greenhouses have been used for potted and cut flower cultivation; fruit tree production is used to cultivate grapes, strawberries, watermelons, melons, peaches and citrus, etc. Greenhouses can provide growth periods and increase production. It is mostly used for planting or raising seedlings of temperature-loving vegetables, flowers, trees and...
