Design and Analysis of the Digging Spring Tooth of Stubble Harvester

Abstract:

The developed corn stubble harvester can simultaneously finish such as the digging, picking up, cleaning, collection and Stripy laying stubble process and so on, but it cost more man-hour time because of the high digging resistance and high engine power consumption in digging stubble works. The digging spring tooth for corn stubble harvester including self-exited vibration S-shaped spring handle and curved chisel-shaped bionic tooth is designed based on the mechanism of drag reduction of self-excited vibration and bionic drag reduction for reduce digging resistance and power consumption, and the statics analysis of digging spring tooth is done by ANSYS software, the stress and strain distribution diagrams show the design is reasonable.
