Abstract: The overall design principle of the ecoplanter and the
development of the planting tree machine of the world is introduced. The
researching focus of the planting tree machine is pointed out both at
home and abroad. Linear modification approximation theory, the method of
Newton-Raphson, are applied to perform kinematics analysis on the
hanging system of the scarification mechanism of ecoplanter. Based on
the results, the theory analysis of the pit shape and the numeral
simulation with the business software Matlab is carried out. It shows
that pit shape changes according to the feed speeds. This makes the
designer understand the kinematics characteristics and structure
characteristics before the ecoplanter is produced. The ecoplanter
designed can defend the vegetations in the ground perfectly with low
energy consumption, high productivity and high survival rate of the
seedling. The mechanized tree planting has important meanings such as
improving the coverage rate of forest in our country, protecting
ecological environment, checking winds and fix drifting sand, etc.
Key words: Ecoplanter Dynamic analysis Linkage mechanism Hanging
