Abstract: The sockets and sucking nozzles inside air field of pneumatic metering device are
difficult to accurately calculate and analyze. Combined with the production practice, the paper
determines the structure parameters and working speed of the socket cylinder-seeder, and uses
Pro/E software to build 3D model of socket cylinder-seeder, sockets and sucking nozzles inside air
field. CFD software is also used to simulate the inside air field of sucking nozzles and sockets
which have three different structure parameters. The simulation shows that the hemispherical
socket is better than conical socket and straight socket in theory; the bigger sucking nozzle
diameter, the stronger sucking ability, and the better sucking effect. The method is suitable for
calculating and simulating complex air field accurately.
