） Abstract： In order to resolve the problem that the existed beet top cutting mechanism could not adjust the cutting thickness, a new profile top cutting mechanism was proposed
Its working principle was analyzed
The kinematic model of this mechanism was established, and the equations of (angular) displacement, (angular) velocity, (angular) acceleration of the key points of this mechanism were derived
The kinematic simulation and optimization software of this mechanism was designed based on Visual Basic 6
0, with which the effect of main parameters such as the sprocket transimission ratio k, the gear pitch circle radius Rc , the swing arm length L1, the profile wheel radius Rf, etc, on the cutting curve of the cutter and the cutting thickness of the beet top were analyzed
A set of optimal parameters was obtained with the method of human-computer conversation, which was L1=520mm
