Device and method for rapidly winding and unwinding outer sunshade screen of sunlight greenhouse

Abstract

The invention discloses a device and a method for rapidly winding and unwinding an outer sunshade screen of a sunlight greenhouse, which belong to the field of protected agriculture. The outer sunshade screen of the sunlight greenhouse is a laterally-wound outer sunshade screen device, and the device mainly comprises a motor, speed reducers, a traction mechanism, a sunshade screen scroll, a guide rail support frame and a stroke control box, wherein the traction mechanism and the sunshade screen scroll are arranged on an output shaft of the speed reducer. Specific connection relationships among the components are that: the motor is connected with a first speed reducer; the first speed reducer and a second speed reducer are fixed; the output shaft of the motor is slowed down by gear trains of the first and second speed reducers, and then realizes output through the second speed reducer; and the two ends of the output shaft of the second speed reducer are connected with the traction mechanism and the stroke control box respectively. The device and the method solve the problems of power-driven winding and unwinding of the outer sunshade screen of the sunlight greenhouse; and the device has the advantages of simple and portable structure, complete functions, running stability, and the overall budget which may be not high and can be born by a user, is easy to operate and convenient to manage and popularize, and does not damage the sunlight greenhouse in a running process.

Description

technical field [0001] The invention belongs to the scope of facility agriculture, and in particular relates to a fast rolling and unwinding machine and method for sunshade nets outside a solar greenhouse. Background technique [0002] The solar greenhouse is an energy-saving product that uses solar heat to keep the greenhouse warm. It is a unique type of greenhouse in northern my country. It is a greenhouse that does not heat indoors. Even in the coldest winter, it only relies on sunlight to maintain A certain temperature level in the room is required to meet the needs of vegetable crop growth. Sunlight not only provides light energy for crops to photosynthesize organic matter, but also provides a reliable guarantee for the temperature in the greenhouse. Therefore, the solar greenhouse emphasizes sufficient lighting and tight insulation. However, in the midsummer season, the temperature in the greenhouse rises too fast. When the temperature exceeds the suitable temperature ...

Problems solved by technology

However, these two driving mechanisms are generally flat curtains or folding curtains, which are mostly suitable for Venlo-type greenhouses, arched greenhouses and long-span greenhouses, but their use in solar greenhouses with arc-shaped outer shading nets is greatly limited. Up to now, there is no machine and method for automatic rolling and unwinding of external sunshade nets for solar greenhouses in China

Especially when the number of solar greenhouses is large, it is a heavy and time-consuming task to roll the external sunshade materials only manually, which largely restricts the growth of summer crops in solar greenhouses and seriously affects the production of solar greenhouses. ability to play
