| Abstract: | According to the results of indoor and field test of the seed-meter device with combined suckers, the performance of the seed-meter is determined. The qualified index of seed space is over 52% and the coefficient of variation of the seed space is less than 29% at a tractor speed of 6 km/h, which quite meets the needs of wheat precision planting. Meanwhile, the effect of several factors on the performance, including rotational speed of the radial slot disc, speed of tractor and falling height of seed, are analyzed in this paper. |
