In order to meet the needs about collecting the soil containing tree species, we designed an automatic cutting machine which can receive loam containing seeds and used in the forest ioam. Features of this machine are the application of the chain plate knife, not only can hierarchical cut loam containing seeds, but also will transport the loam to the collecting bag. In the design process, through building a mathematical model about the chain plate knife cut soil, Analysis of the resistance of working, and get the relationship between the overall level of resistance and the working width. The experimental results show that the machine is easily to be operated, can highly efficient cut soil, and it's suitable for use in the woodlands.
