四川丘陵山区玉米电动播种机设计与台架试验
Design and Bench Test of Electric Corn Seeder in Hilly and Mountainous Areas of Sichuan Province
摘要
Abstract
Aiming at the problems of poor uniformity of corn sowing and low operational reliability caused by steep slopes,deep ditches,fine fields,and sticky soil adhesion in the hilly and mountainous areas of Sichuan Province,a seeding re-search based on electric drive technology was carried out to improve the sowing performance of seed metering device under changing terrain conditions and solve the problem of uneven sowing caused by traditional mechanical seeders due to wheel slippage.The seeder developed integrated a GPS positioning and speed measurement device.By constructing the dynamic coupling operating speed with the seeding amount to achieve adaptive control of real-time and precise adjustment of the sowing distance with the operating speed;Combined with orthogonal test and bench test,the performance of electric drive metering device was verified.The results showed that under the benchmark working conditions(operating speed of 4 km/h,ground height of 10 cm,response time of 200 ms),the seeding qualification index of seed metering was 91.6%,the replay rate and missed rate were 3.7%and 4.7%,respectively,and the performance of seed metering device was stable.In addition,based on the characteristics of electric drive,the system was equipped with a multi-mode gear-box,which could quickly adjust the seeding amount,allowing the motor to work in the optimal range,thereby further im-proving the passability and operational efficiency of complex terrains.The research results provided theoretical basis and technical equipment support for precision seeding of corn in hilly areas.The adaptive control strategy effectively solved the problem of uniform sowing under complex working conditions,and had important practical value for improving the level of regional agricultural mechanization.关键词
