Inflatable greenhouse film

Abstract

The invention discloses an inflatable greenhouse film, which consists of an upper film, a middle film, a bottom film, a matched air guide pipe and an edge sealing film, wherein the upper film, the middle film and the bottom film are equal in both length and width and are overlapped in the same direction. The middle film is overlapped on the bottom film, the periphery of the middle film is respectively connected with the upper edge and the lower edge of the edge sealing film in an iron-welding way, a transverse iron-welding straight joint is arranged at one second of the ridge width c of the middle film in a longitudinal direction, transverse iron-welding straight joints are equidistantly arranged at intervals of ridge width C, and the two films are compounded at an interval to form a lower ridge-shaped air storage layer. The upper film is overlapped above the middle film, the periphery of the upper film is connected with the upper edge of the edge sealing film in an iron-welding way, transverse iron-welding straight joints are equidistantly arranged between the upper film and the middle film at intervals of ridge width c to form an upper ridge-shaped air storage layer, and the upper ridge-shaped air storage layer is directly compounded above the lower ridge-shaped air storage layer. The air guide pipe penetrates through the middle film of the lower ridge-shaped air storage layer from the two sides, air holes are evenly distributed on the wall of the air guide pipe in the middle film, the air holes communicate the upper ridge-shaped air storage layer and the lower ridge-shaped air storage layer, the two ends of the air guide pipe penetrate through the edge sealing film, the air guide pipe is connected with the edge sealing film in an iron-welding way, one end of the air guide pipe is connected with an external air source and the other end of the air guide pipe is an air outlet. After the inflatable greenhouse film is inflated, the thickness is multiplied and the thermal insulation property is obviously increased.

Description

technical field [0001] The invention relates to a greenhouse film for agricultural plastic greenhouses, in particular to an inflatable greenhouse film provided with a multi-layer sealing structure. Background technique [0002] The contemporary horticulture industry generally uses plastic greenhouses, which rationally use plastic greenhouses to increase lighting and heat preservation, artificially create an environment suitable for the production of agricultural plants, vegetables and flowers, and obtain high-yield and high-quality agricultural and sideline products during non-planting seasons or periods to meet people's needs Daily needs. Existing agricultural plastic greenhouses all use plastic shed film as the lighting and insulation layer, and one layer of plastic shed film can meet the requirements of use under normal temperature conditions. Due to the cold weather in winter or early spring, a layer of plastic shed film for agricultural plastic greenhouses cannot meet ...

AI Technical Summary

Problems solved by technology

The biggest problem is that the operation of collecting straw curtains or non-woven fabrics is complicated, labor-intensive, and costly

Another problem is that the multi-layer nesting structure not only occupies a lot of frame materials, but also occupies a limited area in the greenhouse, which directly affects the air circulation and personnel passage in the greenhouse, and reduces the utilization rate of the agricultural greenhouse.
