Modeling of the no-tillage planter and simulation of the cutting-stubble knife

By the virtual modeling technique of Pro/E, the 3D solid modeling was made for the key parts of the no-tillage planter, and virtual machine was assembled. The virtual machine was connected with the tractor model, and the direct of the rectilinear motion was set, then simulation motion of the no-tillage planter had been carried out. The curve was obtained about the displacement, velocity and acceleration of the cutting-stubble knife. The result indicated that simulation curve correlated well with the theory analysis equation. This will provide data for the rational design of the cutting-stubble parts. At the same time, simulation design will shorten the cycle of the product design.
