| Abstract: | The research introduces the precision seeder of small grain. The research adopts the method of two factors five level quadratic orthogonal revolving using experimental design based on design-expert Version 8.0.6 and establishes the mathematical model between the miss seeding rate, the reseeding rate, the breakage rate of seeds, the breakage rate of seeds and the speed of revolution of the seed-metering wheel, the length of the rubber tube of the guide tube in the seeding device test-bed. The result of the experiment shows that the best speed of revolution of the seed-metering wheel is 10r/min and the guide tube can optimize the seeding performance and the length of the rubber tube of the guide tube hardly influence the seeding performance. The research provides the design basis for the new precision seeder of small grain. |
