| Abstract: | One kind of seed-metering device with special cells for cole seed was designed. The configuration and working principle was introduced.The differences between two disposal modes of cells were analyzed.And then,the capability,mainly the uniformity of the seed-metering device was tested in experiments.Based on the request of testing result,the structure of the seed-metering device was changed.Some conclusions were given in the end.The disposal modes of cells are the primary factors which affecting the working... |
