Description

Technical Field

[0001] The invention relates to the technical field of greenhouse cleaning, and in particular to a greenhouse cleaning machine that is self-adhering to a greenhouse surface. Background Art

[0002] A greenhouse is a device used to grow plants. Because it can transmit light and keep heat, it is widely used in the cultivation of non-seasonal crops, which can effectively increase yields. Greenhouses are large in size, and with continuous use, their outer surfaces will be covered with a lot of dust and impurities, which will affect the light transmission and heat preservation performance and even damage the surface. Therefore, it is particularly important to clean the greenhouses in a timely manner. Manual cleaning is not suitable for large-scale greenhouse clusters. For this reason, a variety of automatic cleaning greenhouse cleaning machines have been developed on the market. They usually use a moving mechanism to drive a cleaning brush along the greenhouse setting path to clean the greenhouse surface, which effectively improves the cleaning efficiency. However, the cleaning brush is set on a mounting block with a fixed shape, and the greenhouses have various shapes. The cleaning brush with a single layout cannot reliably fit the greenhouse surface, which affects the brushing effect and has poor reliability. Summary of the invention

The third fixed gear is used to extend the angles between the driving plate and the extension plate and between adjacent extension plates change synchronously to form an arc with variable radius. The layout of each cleaning brush changes accordingly to fit the greenhouse surface of various shapes, effectively improving the cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS
