Abstract

Aiming at the present situation of the use and development of metering device in Mechanized Direct Seeding of rice in China, and the application of virtual prototyping technology and discrete element simulation in agricultural machinery design, a new type of air-suction rice metering device was designed by using CATIA software. The working process of metering device was simulated by CFD-DEM coupling technology, and the results were compared with those of bench test. The optimum structure parameters of the metering device are obtained.
