Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural greenhouse film technology, specifically to a high-transmittance, tear-resistant plastic agricultural greenhouse film. Background Technology
[0002] During seasons unsuitable for crop growth, agricultural greenhouses are set up on farmland to provide a greenhouse growing period and increase yields. Plastic agricultural greenhouses are supported by materials such as bamboo, wood, and steel, and covered with plastic film to form an arched structure for cultivating vegetables. This allows for earlier or later supply, increases yield per unit area, and helps to prevent natural disasters.
[0003] The light transmittance of existing agricultural greenhouse films is easily affected during use. Dust tends to accumulate on the outer side of the film, while water droplets easily form on the inner side. Both of these phenomena affect the light transmittance of the film, which in turn affects the growth of crops. Utility Model Content

[0010] As a preferred embodiment of the above technical solution, the convenient ventilation mechanism includes a hollow connecting ring, which is fixedly connected to the top of the plastic greenhouse film. A raised ring is fixedly installed on the top of the hollow connecting ring, and a rubber ring is fixedly connected to the top of the raised ring.

[0018] Compared with the prior art, the beneficial effects of this utility model are:
[0019] This invention utilizes an organosilicon coating design to form a smooth, hydrophobic layer on the inner surface of the plastic greenhouse film. This allows water droplets to slide smoothly down the inner surface of the film, preventing excessive water droplets from affecting light transmittance. The nano-coating design also gives the outer surface of the film low surface energy, reducing the adhesion rate of dirt and grime, further improving light transmittance and ensuring optimal crop growth within the greenhouse. The combination of aramid fiber and glass fiber layers enhances the tear resistance of the film, extending its lifespan. Attached Figure Description

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0027] like Figures 1-5 As shown, this utility model provides a technical solution: a high-transmittance, tear-resistant plastic agricultural greenhouse film, comprising a plastic greenhouse film 1, with ventilation holes 15 on the outer surface of the plastic greenhouse film 1, a convenient ventilation mechanism 2 located at the ventilation holes 15 on the plastic greenhouse film 1, an aramid fiber layer 11 fixedly connected inside the plastic greenhouse film 1, a glass fiber layer 12 fixedly connected inside the plastic greenhouse film 1 below the aramid fiber layer 11, an organosilicon coating 13 fixedly connected to the bottom of the plastic greenhouse film 1, and a nano-coating 14 fixedly connected to the top of the plastic greenhouse film 1. The coating 13 forms a smooth hydrophobic layer on the inner surface of the plastic greenhouse film 1, allowing water droplets to slide smoothly down the inner surface of the plastic greenhouse film 1, reducing the adhesion rate of water droplets. The nano-coating 14 gives the outer surface of the plastic greenhouse film 1 a low surface energy, reducing the adhesion rate of dirt and grime on the outer surface of the plastic greenhouse film 1, fully improving the light transmittance of the plastic greenhouse film 1, and ensuring the growth effect of crops inside the plastic greenhouse film 1. Through the combination of the aramid fiber layer 11 and the glass fiber layer 12, the tear resistance of the plastic greenhouse film 1 can be improved, avoiding the problem that the plastic greenhouse film 1 is easily damaged when subjected to external force.
[0028] As one implementation method in this embodiment, such as Figures 1-3As shown, the aramid fiber layer 11 is shaped as an oblique mesh structure, the glass fiber layer 12 is shaped as a right-angle mesh structure, the thickness of the silicone coating 13 is set to 5-10 μm, and the thickness of the nano coating 14 is set to 15-20 μm. By setting the shapes of the aramid fiber layer 11 and the glass fiber layer 12, their combined operation can further enhance the tear resistance of the plastic greenhouse film 1. By designing the thickness of the silicone coating 13, its functionality can be guaranteed while reducing the overall thickness of the plastic greenhouse film 1. By designing the thickness of the nano coating 14, the nano coating 14 can be exposed to the natural environment, thus extending its service life.
[0029] As one implementation method in this embodiment, such as Figure 4 , Figure 5 As shown, the convenient ventilation mechanism 2 includes a hollow connecting ring 21, which is fixedly connected to the top of the plastic greenhouse film 1. A protruding ring 22 is fixedly installed on the top of the hollow connecting ring 21, and a rubber ring 23 is fixedly connected to the top of the protruding ring 22. A transparent sealing plate 24 is movably connected to the top of the rubber ring 23. An elastic bladder 27 is fixedly connected to the top of the hollow connecting ring 21, and the outer surface of the elastic bladder 27 is movably connected to the bottom of the transparent sealing plate 24. A protruding block 25 is fixedly installed on the inner surface of the hollow connecting ring 21, and an elastic element 26 is fixedly installed on the top of the protruding block 25. The top of the elastic element 26 is fixedly connected to the bottom of the transparent sealing plate 24. A hollow block 28 is fixedly connected to the outer wall of the hollow connecting ring 21. The top is fixedly connected to an interface 29. After spraying insecticide or when the outdoor temperature is high, the greenhouse needs to be ventilated. The end of the interface 29 is connected to the same pipe in advance. Gas is filled into the pipe with the help of an air pump. The gas then passes through the hollow block 28 and the hollow connecting ring 21 into the interior of the elastic bladder 27. The elastic bladder 27 expands to push the transparent sealing plate 24, causing the transparent sealing plate 24 and the rubber ring 23 to be unsealed. This allows the interior of the greenhouse to be ventilated and the gas inside the pipe to be discharged. The elastic force of the elastic element 26 can drive the transparent sealing plate 24 to reset and stick to the rubber ring 23, thus sealing the interior of the greenhouse. This improves the speed of ventilation or deventing of the greenhouse and ensures the safety of crops.
[0030] Working principle: First, the support frame structure is installed on the ground, and then the plastic greenhouse film 1 is covered on the support frame structure to protect the crops. During use, the organosilicon coating 13 can form a smooth hydrophobic layer on the inner surface of the plastic greenhouse film 1, reducing the adhesion rate of water droplets on the inner surface of the plastic greenhouse film 1. The nano coating 14 can make the outer surface of the plastic greenhouse film 1 have low surface energy, reducing the adhesion rate of dirt and ash on the outer surface of the plastic greenhouse film 1. Through the combination of aramid fiber layer 11 and glass fiber layer 12, the tear resistance of the plastic greenhouse film 1 can be improved.
[0031] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
