Design of a desert grass grid sand barrier laying device

Deserts are typically aeolian landforms characterized by sandy, decertified terrain with sparse vegetation, low rainfall, and dry air. These regions often experience erosion and varying degrees of dandification, which can become irreversible. This process leads to a loss of biodiversity, a decline in arable land, and, in extreme cases, the destruction of cities. Moreover, desertification can impact the surrounding ecological environment and even alter the climate of entire regions, threatening both ecosystems and human survival. In the present work, a desert grass grid sand barrier laying device was developed to efficiently deploy sand barriers made of materials like straw, rice straw, and reeds. We optimized structural design using Unigraphics NX and manufactured prototypes based on the design model. The proposed device is intended for use in desertification control efforts, particularly to stabilize moving sand dunes along railways, highways, and desert margins. It helps form protective bands at the desert's edge, gradually increasing fixed sand areas, enhancing vegetation coverage in sandy regions, and reducing land dandification and desertification. By improving ecosystem stability and ecological services, this device can play a vital role in controlling desertification and gradually reversing land degradation.
