In order to effectively improve the efficiency and quality of grass grid laying,and promote the progress of grass grid laying from mechanization to automation and intelligence,a mechanical vehicle for automatic grass grid laying was designed based on the manual grass grid laying process,using scattered grass as raw material.It is used to complete grass composition,feeding,planting,and fixing actions,and on this basis,the mechanical vehicle is en-dowed with the functions of sowing and spraying soil amendments,to solve the problem of numerous manual grass laying processes,a comprehensive sand control approach is achieved by combining engineering sand control,biologi-cal sand control,and the use of soil amendments.In addition,path optimization is carried out,innovative laying modes are innovated,and a combination of three sided staggered laying mode and single sided mode is used to effec-tively avoid damage to the laid grass grid.Provide solutions for the use of loose grass and the transition from mechani-zation to intelligence.
