Study on Seeding Performance Optimization of Sugarcane Disease-Free Seed Canes Double-Bud Trough-type Planter
摘要
Abstract
Sugarcane disease-free seed cane planting technology is one of the effective technical measures to improve the unit yield level and quality and reduce the production cost.At present,the domestic sugarcane mechanized planting tech-nology is not mature,which directly limits the popularization and application of this technology.Aiming at this problems,this paper takes the orderly arrangement of sugarcane healthy seedlings and double bud sugarcane seeds as the research object,optimizes the seed metering performance of 2czd-2a semi-automatic double bud sugarcane planter developed by the team,designs a high-frequency electromagnetic vibration auxiliary feeder and profiling seed metering synchronous driver,uses solid edge ST5 three-dimensional software modeling for simulation analysis,establishes a test-bed for multi factor orthogonal combination test.Collect data and use SPSS to process,establish regression equation,use Design Expert to draw response surface,analyze the interaction between factors,use MATLAB to optimize parameters,and finally carry out field test verification.The results show that the synchronous driving mechanism increases the sowing uniformity;When the pulley speed is 10 r/s,the vibration amplitude is 18.5mm and the traveling speed is 0.65m/s,the sowing uniformity reaches 94.18%,and the deviation from the optimization result is less than 5%,which meets the design re-quirements;There is no interference between high-frequency vibration and power source vibration,which verifies the feasibility of vibrator carding scheme,and provides a reference for the research and development of full-automatic planter.关键词
