Multi-protection structure-based intelligent roller blind device for agricultural greenhouse

Abstract

The invention provides a multi-protection structure-based intelligent roller blind device for an agricultural greenhouse. The multi-protection structure-based intelligent roller blind device for the agricultural greenhouse comprises a greenhouse body, bottom fixing frames, a left reinforcing rib, a right reinforcing rib, an aluminum alloy hollow plate, a left fixing frame, a right fixing element,an intermediate protective frame structure, a left arc-shaped rod, a right arc-shaped rod, a left roller blind, a right roller blind, winding frame structures, positioning frame structures and a control frame structure, wherein the bottom fixing frames are arranged at the front side and the rear side of the lower part of the greenhouse body through bolts. A top protective cover is arranged at theupper end of a longitudinal rod through screws, and a sunscreen function for the retracted left roller blind and the right roller blind in use is facilitated, so that the left roller blind and the right roller blind are prevented from being frequently exposed to the sun to be damaged; and puller bolts penetrate through side fixing pipes and are in threaded connection with the upper end of the leftarc-shaped rod or the right arc-shaped rod, so that a good fixing effect on the upper end of the left arc-shaped rod or the right arc-shaped rod in use is facilitated.

Description

technical field [0001] The invention belongs to the technical field of agricultural equipment, and in particular relates to a rolling shutter device for an intelligent agricultural greenhouse based on a multiple protection structure. Background technique [0002] With the emergence of high molecular polymers - polyvinyl chloride and polyethylene, plastic films are widely used in agriculture. In the early 1950s, Japan, European and American countries successfully applied greenhouse films to cover hotbeds, and then covered small sheds and greenhouses with good results. my country introduced polyvinyl chloride agricultural film in the autumn of 1955. It was first used to cover vegetables in small sheds in Beijing, and achieved the effect of early maturity and increased production. The greenhouse was originally a special equipment for vegetable production. With the development of production, the application of greenhouses has become more and more extensive. At present, greenho...

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a rolling shutter device for intelligent agricultural greenhouses based on multiple protective structures, so as to solve the problem that the existing rolling shutter devices for agricultural greenhouses do not have the ability to automatically lift the rolling shutter according to the demand, and do not need to be blocked. The protective effect of the curtain is poor, it is inconvenient to play a positioning function on the roller shutter frame and the ventilation effect on the control frame is poor
