The air-suction seeder s one kind of advanced sowing seeds machinery,by its unique merit by domestic and foreign widespread uses,But the present domestic this sowing-seeds’s operating speed is generally low,and various viciouses,with overseas compare have the big disparity。To further enhance the country’s air-suction seeder performance, the paper on the air-suction Precision planter for a large number of pilot studies.First,the air-suction seeder for the adsorption mechanism is analyzed,and the seeds of the kinetic analysis of the situation.And air-suction seeder the performance parameters of the impact analysis be affected sowing of the seed quality is the main factor hole diameter hole and the number of points, such as the diameter.Secondly, through simulation test to initial information, the vacuum pressure in certain conditions, In the hole diameter, as well as the number of holes the diameter of the three points under the influence of the changes of evaluation indicators. In the theoretical analysis and simulation experiments designed on the basis of 2BS-360 the air-suction seeder for Sowing Rice in Bowl-seedling Tray Which Made of Straw,And the process of its work. .Sowing in the test stage, by changing the seeding for the different parameters (hole diameter, as well as the number of points hole diameter, etc.),planting their performance on the test, That affected sowing of the secondary factors for the hole diameter, and the number of hole diameter Points,And come with the passing rate among single grain rate, the relationship between the rate at regular intervals. At the same time a test of the three orthogonal factors and the relationship between the pass rate analysis,Access the regression equation. Through the optimization of the regression equation obtained for the seeding for the best combination of parameters: 1.5mm, 3, 14 mm.
