Description

Retractable rain shelter

Technical Field

The utility model relates to the technical field of agricultural devices, in particular to the technical field of cultivation or auxiliary cultivation, and particularly relates to a retractable rain shelter which is used for providing rain sheltering and sun shading for a cultivation nursery.

Background

Nursery cultivation requires accurate control of the fruit and vegetable seedlings under cultivation, including temperature, humidity, moisture and sunlight, so that the seedlings can have a good growing environment. Generally, seedlings in the early stage are cultivated in a greenhouse, and seedlings in the middle stage are moved to the outside of the greenhouse or the inside of the greenhouse with a full window after having certain adaptability to the environment, so that the seedlings can gradually contact and adapt to the natural environment. For seedlings, nutrition and moisture are both artificially controlled, the most critical photosynthesis is that the seedlings have to be and are not easy to control, if the sunlight is too strong, the seedlings are burnt, and if the sunlight is too strong, the root rot is easily caused by excessive moisture. Therefore, it is most important for the young plants to contact and adapt to the natural environment to receive the proper amount of sunlight and rain, so it is very important for the young plants to be shaded from sunlight and rain to thrive.

The existing sunshade or rain shelter usually adopts a high-strength fixed shed film or a hinge type support arm shed film, the structure is relatively complex, the strength requirement of the structure is high, a large number of steel pipes or aluminum alloy square pipes are required to be manufactured, the cost is high, the weight is heavy, and the rapid folding and unfolding are not facilitated.

In order to replace the existing heavy rain shelter, a rain shelter which is more effective, more convenient to fold and unfold, lighter in structure and simple is needed so as to adapt to the rain shelter of a large-area nursery.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems that the existing rain shed is complex in structure and heavy, and cannot be rapidly folded and unfolded, the application provides a foldable rain shed which can comprehensively solve the technical problems that the existing rain shed is complex in structure and inconvenient to fold and unfold. The steel cable type sliding folding and unfolding shed film is adopted, and the shed film is arranged according to an array, so that large-area rapid folding and unfolding is realized; the steel cable is retracted by sliding, so that the device has the advantages of small resistance, high efficiency and high retraction speed; simultaneously, can be with arbitrary control of canopy membrane opening size, the practicality is strong.

In order to achieve the purpose, the technical scheme adopted by the application is as follows:
