Design description: The background of the design is due to the gradual deterioration of the global environment, especially on the issue of desertification, which has a significant impact on human life. People have gradually realized the seriousness of the problem and launched corresponding measures. Grass grid sand fixation is one of the most effective measures. It can fix sand dunes in the form of squares through plant fibers or chemical fiber materials, slow down the flow rate of the desert, and promote the sand in the squares to gradually transform into plantable soil. However, manual laying is mostly used, which leads to low efficiency and waste of human resources. This product adopts unmanned, mechanical automation grass grid laying fixed sand dunes, saving human resources and improving efficiency. In addition, a low and wide body is adopted to strengthen the climbing ability, which can work on sand dunes with steeper and higher slopes and improve the laying range. There are also water spray wet sand, gear ploughing, horizontal laying, integrated to solve the problem of grass grid laying. Through the cooperation of machinery and labor, we will further accelerate the control of land desertification and make a contribution to nature.
