Vegetable greenhouse bringing convenience to sunshading

Abstract

The invention discloses a vegetable greenhouse bringing convenience to sunshading. The vegetable greenhouse comprises a group of greenhouse supports uniformly arranged on the ground, a transparent film is arranged on the outer sides of the greenhouse supports, a circular arc guide pipe is arranged under each greenhouse support, two rotary shafts are symmetrically arranged on the two sides of the upper portions of the guide pipes, and each rotary shaft is fixedly connected to the greenhouse supports through a group of hanging brackets. A group of net rods is in sliding connection with the upperportions of the guide pipes, and a shunshading net is connected between every two adjacent net rods. Two groups of tension ropes are arranged on the two net rods on the outer side respectively, and each tension rope is fixedly connected with the corresponding rotary shaft. The vegetable greenhouse has the advantages that the structure is simple, a traditional manual pull cover mode is adopted, the construction cost is low, and the greenhouse can be used in general farmers' families; by means of the vegetable greenhouse, the sunshading net laying speed is high, unnecessary pulling actions areavoided, and the service life of the sunshading nets is prolonged; when the vegetable greenhouse is covered with the sunshading nets, only one man can cover the vegetable greenhouse with the sunshading nets, and labor cost is greatly saved.

Description

technical field [0001] The invention relates to the technical field of sunshading for vegetable greenhouses, in particular to a vegetable greenhouse which is convenient for sunshading. Background technique [0002] The vegetable greenhouse is a frame-covered structure with excellent thermal insulation performance. It appears that people can eat off-season vegetables. Generally, the vegetable greenhouse uses a bamboo structure or a steel structure frame, covered with one or more layers of thermal insulation plastic film, thus forming a greenhouse space. The outer film can well prevent the loss of carbon dioxide produced by the growth of vegetables inside, so that the shed has a good heat preservation effect. [0003] The temperature difference between day and night in some areas of our country is relatively large. At night, vegetables need to be kept warm by vegetable greenhouses, while the temperature is relatively high during the day, and the outside sunlight is particular...

AI Technical Summary

Problems solved by technology

[0005] Ordinary agricultural families usually use sunshade nets on the outer surface of vegetable greenhouses to shade the sun, and vegetable greenhouses are generally long and relatively large in height. Farmers need at least 3 people to lay sunshade nets on the roof of the shed, which is time-consuming and laborious. It is not conducive to increase agricultural productivity
