气吸式花生单粒精密播种机设计与试验
Design and Test of Air Suction Peanut Single Seed Precision Seeder
摘要
Abstract
In order to solve the problem of backwardness of peanut single grain precision sowing equipment in China,a two rows of a row of air suction peanut single grain precision sowing machine was designed,which can be completed in one go to start ridging,furrowing,fertilizer application,seeding,mulching and filming.The design had calculated the parameters such as the diameter of seed discharge disc,the diameter and number of seed suction holes,and had deter-mined the corresponding relationship between the gear position of the speed regulating mechanism and the spacing of so-wing;had calculated the effective working length of the outer grooved wheels to meet the actual amount of fertilizer dis-charge;and based on the structural dimensions of peanut ridges and the requirements for the sowing depth,had separate-ly designed and calculated the depth of the ridging shovel and the diameter,angle,and polygonal angle of the disc of the double-disc furrow opener,respectively.The key parameters of profiling mechanism were designed to ensure the consis-tency of sowing depth of seeder.The test results had showed that when the negative pressure was 5.16 kPa and the speed was 4.34 km/h,the qualification rate was 94.6%,the leakage rate was 3.0%,and the replanting rate was 2.4%,and the indexes were in line with the standard requirements.关键词
