A triangle layout of the mechanism of cleaning leaves and breaking tails based on the force analysis of motion of the sugarcane and its material properties was presented. It successfully achieves the functions of raking and cleaning leaves, and breaking tails. The orthogonal experiment on the self developed experiment platform was carried out to verify the effect of the layout and find out the optimal parameter combination. According to the experiment, the optimal combination is: the rotating speed of the raking roller of 700 r/min, the speed of the cleaning roller of 900 r/min, the interaction depth of the raking teeth of 40 mm, and the interaction depth of the cleaning element of 30 mm. The experiment results show that the inverted goods font layout of the mechanism is effective and feasible.
