Design for ridge cleaning equipment of no-tillage planter based on Pro/E

The residues cutting and ridge cleaning equipment of ridge-tillage planter are important working parts which can prevent no-tillage planter from clogging and ensure good quality of seeding. While ridge cleaning equipment is in operation, the residues often fall onto the neighboring ridge instead of falling into the furrow. So, the factors influenced the motion trace of residues are needed to be analyzed, optimized for making residues fall into the furrow. For this, how to use Pro/E software to establish the simulation model of residues cleaning equipment was introduced, and the simulation analysis of its ridge cleaning was done in this paper. The analysis results showed that the main parameters influenced the motion trace of residues is forward speed v of residue cutting and ridge cleaning equipment, oscillatory speed of level disc and the open-close angle of the back wings of ridge cleaning equipment. By taking different a and simulating the level disc and observing the motion of residues ,the better location of residues was achieved when v=1.153 m/s and a?=60°～120°,which provided the technology support to the design of residues cutting and ridge cleaning equipment of ridge and no-tillage planter.
