| Abstract: | A precision rice direct-seeding mechanism was designed by the theory of grain grading-sifter and a V-channel metering pan was made. The rice seeds will throw out once for each vibration of the V-channel metering pan. The experiments of the precision rice direct-seeding were conducted to test the number of rice seeds thrown out, the diameter of the hill, the average hill spacing and the average row spacing, the variability of the hill spacing, and the row spacing. The experimental results concluded that the test parameters could meet the requirments of design. |
