Design of Key Components of Straw Pulverizer

With rapid development of agriculture，more and more straws are produced in agriculture.If these straws can not be properly treated，it will not only affect normal work of farmers，but also cause serious damage to natural environment.Taking key working parts of straw crusher as main research object，key working parts of straw crusher were analyzed and designed.Through mechanical analysis of main shaft of crusher and study of stress under different loads，feasibility of design was discussed.
