Discrete particles often become the work objects or working medium of the modern agricultural equipment. Research work of particle collisions and fluid-solid coupling is always be involved in the study of particles movement. It is show that the methods and results of these researches are more and more important to the other research work in modern agricultural engineering field. The research methods of particle movement in agricultural engineering field were respectively illuminated from these aspects like theory analysis, numerical simulation and actual experiment. Then the status of particle movement research for a few typical agricultural equipments both in China and aboard was reviewed. Finally, the development tendency of particle motion research in agricultural engineering realm was proposed. 
