a greenhouse device

Abstract

The invention discloses a greenhouse device. The greenhouse device comprises a base, two base supports, a top film device, a side film device and a top supporting rod. The top film device comprises two annular sleeves connected together. Each sleeve is internally provided with a core shaft and a film roll arranged on the core shaft in a sleeved mode. The two annular sleeves are provided with symmetrical openings. The edges, extending out of the openings, of films of the film rolls are provided with hooks. The lower end of the top film device is provided with a connecting piece used for being connected with the top supporting rod. The side film device comprises a cylinder which is internally provided with a core shaft and a film roll, the cylinder is provided with an opening and a connecting port, and the edge, extending out of the opening, of a film of the film roll is provided with a hook. The side film device is connected with the base through the two base supports. The extensible film greenhouse is simple in structure, convenient to install, there is no fixed requirement for the installation size, and greenhouses with various sizes can be installed through the greenhouse device.

Description

technical field [0001] The invention relates to a plastic film greenhouse, in particular to a greenhouse device. Background technique [0002] With the emergence of high molecular polymers - polyvinyl chloride and polyethylene, plastic films are widely used in agriculture. The greenhouse was originally a special equipment for vegetable production. With the development of production, the application of greenhouses has become more and more extensive. At present, greenhouses have been used for potted flower and cut flower cultivation; fruit tree production is used for cultivating grapes, strawberries, watermelons, melons, peaches and citrus, etc.; forestry production is used for tree seedling cultivation and ornamental tree cultivation; Chicken, cattle, pigs, fish and fry, etc. Due to the complexity of the installation of plastic greenhouses, the size of the film and the size of the brackets required for different sizes of greenhouses are different. In some places where veget...

AI Technical Summary

Problems solved by technology

Due to the complexity of the installation of plastic greenhouses, the size of the film and the size of the brackets required for different sizes of greenhouses are different. In some places where vegetables are produced on a large scale, plastic greenhouses are installed and used on a large scale due to the large amount of use required for installation. However, for some small-scale farmers, especially in some places in southern China, the per capita land is very small. In order to make full use of the land, the size of the greenhouses of each family is often different. After the greenhouses are built It will be disassembled according to the needs of different seasons. This kind of workload is very large for small farmers' workshops in rural areas, and the cost is high, which seriously affects the economic interests of farmers.
