Three-layer vegetable tunnel with single heat preservation quilt

Abstract

The invention discloses a three-layer vegetable tunnel with a single heat preservation quilt. The vegetable tunnel comprises a tunnel bracket and a heat preservation film, wherein the upper portion of the tunnel bracket is covered with the heat preservation film. The tunnel bracket is fixed to stand columns through oblique supports. A fancy arching is arranged above the tunnel bracket. The fancy arching is provided with a movable supporting device. The upper portion of the movable supporting device is covered with a heat preservation film, and the heat preservation quilt is arranged on the upper portion of the heat preservation film. Two adjacent arching bodies in the middle of the fancy arching form an arching rail combination. The arching rail combination is provided with a rolling device. A simple arching is arranged in a tunnel body and covered with a manual rolling film. A snow scraping device is further arranged above the fancy arching. According to the vegetable tunnel, the construction area is small, cost is low, when the tunnel with the actual planting area being equal to the actual planting area of a solar vegetable greenhouse is constructed, the cost of the tunnel is only one half or slightly higher than one half that of the greenhouse, and the utilization rate of the tunnel is two times that of the greenhouse. Besides, the vegetable tunnel has the advantages of being safe, scientific, reliable, feasible and capable of saving labor.

Description

technical field [0001] The invention relates to a vegetable shed, which belongs to the technical field of agricultural production. Background technique [0002] Although the development and promotion of the arch shed is not as popular as the solar greenhouse, its development trend and speed are relatively fast. It has the following three advantages. First: the construction area cost is low, and the construction of an arch shed with the same planting area as the solar greenhouse vegetable greenhouse is only one third or slightly higher than one third of the cost of the greenhouse; second: its planting structure is highly variable During the high temperature period, there is no need to rest stubble. Due to the low cost per unit area and the rising price of off-season vegetables, the construction of arched sheds is popular; The rate is more than twice that of the greenhouse. With the continuous rise of land prices, more and more attention has been paid to the utilization rate ...

AI Technical Summary

Problems solved by technology

Although arch sheds have the above three advantages, people who plant arch sheds are no longer satisfied with the status quo. Because arch shed vegetables are limited by temperature conditions, the price of vegetables produced often lags behind the peak price in early spring, so some growers have begun to consider changing it. structure

For example: adding insulation quilts and installing roller blinds, but the prototype design of the shed is not suitable for installing roller shutters and insulation quilts. If the status quo is to be changed, new contradictions will arise. In case of rain and snow, how to cover the film and retract the film every day very inconvenient
