Concerning the nonuniformity problem when sampling in current single grain moisture on-line inspection devices, this paper designed a new grain sampling device by analysing the physical property parameters of grains. The design of the sampling device is optimized by combining computer mode and physical experiments. In condition of ensuring single grain sampling, fixed the structure parameters of sampling rollers for South grains and North-east grains. The structure parameters of South grain sampling roller groove is length 18mm, width 2.5mm, depth 3mm. The structure parameters of North-east grain sampling roller groove is length 15mm, width 4mm, depth 4mm.
