Description

Technical Field

[0001] The utility model relates to the technical field of agricultural film products, in particular to an inflatable heat-preserving agricultural film. Background Technique

[0002] Agricultural film, also known as plastic film, mainly consists of polyethylene. Greenhouse agricultural film is a commonly used plastic film in agricultural production, mainly used for the construction of protected agriculture such as greenhouses and sheds, and has functions such as heat preservation, moisture preservation, and light regulation, which is of great significance for improving the yield and quality of crops.

[0003] At present, the heat preservation of existing greenhouses mainly uses greenhouse insulation quilts to cover the greenhouses for heat preservation. When it rains or snows during the day, using the greenhouse insulation quilts to keep the greenhouses warm, the rain and snow soak the greenhouse insulation quilts, and the weight of the greenhouse insulation quilts increases, which is extremely easy to collapse the greenhouse. Moreover, when the greenhouse insulation quilts cover the greenhouse, the greenhouse lacks light, which affects the growth of the planted crops in the greenhouse.

[0004] Therefore, we make improvements and propose an inflatable heat-preserving agricultural film. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides an inflatable heat-preserving agricultural film, which solves the problems in the prior art that when it rains or snows during the day, the rain and snow soak the greenhouse insulation quilts, the weight of the greenhouse insulation quilts increases and it is extremely easy to collapse the greenhouse, and when the greenhouse insulation quilts cover the greenhouse, the greenhouse lacks light and affects the growth of the planted crops in the greenhouse.

[0006] To achieve the above purposes, the utility model is realized through the following technical solutions: an inflatable heat-preserving agricultural film, including an inflatable front film and inflatable assembled films. There are multiple inflatable assembled films, and the multiple inflatable assembled films are arranged horizontally and connected in series. The inflatable front film is arranged horizontally and connected in series with the inflatable assembled film at the front end;

[0007] The inflatable front film and the inflatable assembled films include air bags and connecting film pieces. There are multiple air bags, and the air bags are cylindrical air bag structures. The multiple air bags are arranged longitudinally. There are multiple connecting film pieces, and the connecting film pieces are fixedly arranged on the outer walls of two adjacent air bags;

[0008] The two ends of the air bags and the connecting film pieces overlap, and the air bags and the connecting film pieces form a water guide groove;

[0009] The end side walls of the multiple air bags are connected in series through an inflatable film tube. The inflatable film tubes of the inflatable front film and the inflatable assembled films are connected through a connector. The inflatable film tubes of adjacent inflatable assembled films are connected through a connector.

[0010] As a preferred solution, the end side wall of the air bag disposed in front of the pre-inflation film is provided with an inflation nozzle, a deflation nozzle and a pressure safety valve from top to bottom in sequence. The inflation nozzle is connected with an air path. The deflation nozzle is used to release the air in the air bag, and the pressure safety valve is used to adjust the air pressure in the air bag to prevent the air bag from bursting due to excessive air pressure.

[0011] As a preferred solution, the upper surface of the lower end of the air bag is provided with a threaded folding layer, and the threaded folding layer can bend the air bag.

[0012] As a preferred solution, fixed membrane tubes are provided at the upper and lower ends of the pre-inflation film and the inflated assembled film, and the inner cavities of the fixed membrane tubes fix the pre-inflation film and the inflated assembled film by inserting iron wires.

[0013] As a preferred solution, fixed pressure membrane pieces are provided on one side of the pre-inflation film close to the inflated assembled film and on both sides of the inflated assembled film, and the adjacent fixed pressure membrane pieces of the pre-inflation film and the inflated assembled film are stacked.

The air in the air bags can isolate the heat loss of the greenhouse and play a heat preservation role, and the water guide groove can drain rain and snow to prevent the greenhouse from collapsing due to rain and snow. In addition, while the air bags keep the greenhouse warm, light can enter the greenhouse and will not interfere with the growth of the planted crops.

[0030] The end side walls of multiple said air inflation bags 3 are connected through an air inflation membrane tube 6.

[0031] The end side wall of the air inflation bag 3 arranged on the front side of the pre-inflation membrane 1 is successively provided with an inflation nozzle 8, a deflation nozzle 9, and a pressure safety valve 10 from top to bottom. The inflation nozzle 8 is connected with an air path. The deflation nozzle 9 is used to release the air in the air inflation bag 3, and the pressure safety valve 10 is used to adjust the air pressure in the air inflation bag 3 to prevent the air inflation bag 3 from bursting due to excessive air pressure.

[0032] The upper surface of the lower end of the said air inflation bag 3 is provided with a threaded folding layer 11, and the threaded folding layer 11 can bend the air inflation bag 3.

[0037] The working principle of the utility model:

[0038] Cover the pre-inflation membrane 1 on one side of the vegetable greenhouse frame. Fix one end of multiple iron wires on the upper part of one side of the vegetable greenhouse frame.

When the air pressure in the airbag 3 is greater than the preset air pressure, the pressure safety valve 10 discharges the air in the airbag 3 and keeps the air pressure in the airbag 3 constant, and then the air path of the inflation nozzle 8 is disconnected;

[0042] When the vegetable greenhouse does not need to be insulated, the deflation nozzle 9 is opened to discharge the air in the airbag 3.
