At present, the land management mode in Shandong has changed. The rotation system of wheat and corn is two ripe for one year. The situation causes wheat sowing time become tense, and the existing machinery is inefficient. In order to solve the above problems, a kind of wheat planter was developed by pneumatic conveying with no-tillage. The seeding machine can finish stubble, fertilizing, sowing, covering and pressing at one time. The pneumatic conveying seeds/fertilizers device was utilized in seeds and fertilizers discharging device of wheat planter, which used the same air duct to simultaneously transport the discharged seeds and fertilizers. The form of seeds/fertilizers transportation was the combination of mechanical trough wheel and pneumatic conveying. The diameter of the grooved wheel was 60mm and its effective length was 1100mm. This kind of seeds metering device could improve the efficiency and uniformity of seeds/fertilizers at the same time, which ensured the synchronization of seeds/fertilizers. And the velocity of air flow was determined to be 24m/s. The seeds and fertilizers settling chamber were designed according to the principle of cyclone separator. Their diameter was determined to be 102mm, and the ratio of height to height was 3.5. According to the agricultural requirements of wide band seedling, the structure of wide mouth swallowtail type seeds arrangement device was adopted. The shape of the seeds outlet was “saddle” with high in the middle and low on both sides. The width of the seedling band could reach 12cm. The soil covering device was counter rotating auger to cover the soil from both sides to the middle. It could effectively ensure the consistency of the covering depth and the smoothness of the surface after sowing, which laid the foundation for the uniformity of planting depth. The whole machine was tested in the field. The test results showed that the machine with good trafficability characteristic. The qualification rate of seeds depth was 93.0%, the qualified rate of fertilizers depth was 93.6% and the qualified rate of spacing between seeds and fertilizers was 85.4%. The coefficient of variation was 4.7%, 2.8% and 5.3%, respectively. The average width of the seedling belt was 11.83cm. The qualified rate was 94.5% with the coefficient of variation of 4.2%. The indexes fully conformed to the requirements of the design and agronomy.
