A large-span multifunctional plastic greenhouse

Abstract

The invention discloses a large-span multifunctional plastic greenhouse which comprises vertical columns. A truss is fixedly mounted at the top end of the vertical columns, steel wires are horizontally arranged on the upper surface of the truss in a drawing manner, a greenhouse film is fixedly laid on the upper portion of the steel wires, heat preservation quilts are symmetrically arranged in themiddle of the top of the truss, rectangular ventilation openings are fixedly mounted on two sides of the top of the truss, a speed reducing motor is fixedly mounted on the inner wall of one side of each rectangular ventilation opening, the bottom ends of the rectangular ventilation openings penetrate the truss, an insect-proof net is fixedly mounted between the inner walls of the bottom ends of the rectangular ventilation openings, sunshine plate sealing covers are arranged at the tops of the rectangular ventilation openings, output shafts of the speed reducing motors are fixedly connected with threaded rotating shafts, first sliders symmetrically sleeve the surface of each threaded rotating shaft in a threaded manner, and a riveting frame is fixedly mounted on one side, close to the corresponding rectangular ventilation opening, of each sunshine plate sealing cover. The greenhouse is reasonable in structure, the ventilation automation degree of the greenhouse is improved, internal environment adjustment and control of the greenhouse is enhanced, the available time of the greenhouse is prolonged, and the utilization effect of the greenhouse is improved.

Description

technical field [0001] The invention relates to the technical field of plastic greenhouses, in particular to a large-span multifunctional plastic greenhouse. Background technique [0002] At present, most of the traditional agricultural production greenhouses have small spans, small space, low land utilization rate, and inconvenient mechanized operations. Besides, there is a lack of necessary environmental control measures except for the bottom vents. During low temperature in winter and high temperature in summer, a There are about four months in the middle of the year when normal production is not possible, and the utilization time of the greenhouse is short and the utilization effect is poor. Therefore, we have designed a large-span multi-functional plastic greenhouse to solve the above problems. Contents of the invention [0003] The object of the present invention is to solve the problems of short utilization time and poor utilization effect of existing greenhouses, a...
