摘要
牧草捡拾打捆技术是我国畜牧业现代化发展的重点,而圆捆机捡拾装置的捡拾质量是制约牧草现代化收获的关键性因素。文章以9YG-1.2型圆捆机捡拾装置为研究对象,研究捡拾装置部件运动规律,分析各部件不同参数对捡拾装置捡拾质量的影响。通过ADAMS多体动力学仿真软件对捡拾装置各部件运动状态进行仿真研究,并利用响应面分析法对参数进行匹配优化。最终分析获得9YG-1.2型圆捆机捡拾装置各部件参数的最优组合:曲柄长度90mm、滚筒半径163.5mm、滚子半径16.1mm、机构前进速度1.28m/s、滚筒转速68r/min、弹齿与曲柄夹角50°。通过对比试验分析发现漏检率和弹齿最大加速度分别降低至0.677%和39507.1mm/s^2,相比原有机构优化13.5%和21.8%。
The exfoliation and baling technology of pasture is the key point of the modern development of animal husbandry in China.The exfoliation quality of the exfoliation device of round baling machine is the key factor restricting the modern harvest of pasture.This paper studies the movement of the 9YG-1.2 round baler,pickup device and analyzes the influence of different parameters of each component on the pickup quality of the device.By means of ADAMS multi-body dynamics simulation software,the motion state of each part of the pickup device was simulated and optimized by using response surface analysis method.Final analysis for 9YG-1.2 round baler for the parts collecting device parameter optimal combination: crank length is 90 mm,roller radius is 163.5 mm,roller radius is 16.1 mm,speed of tractor is 1.28 m/s,roller speed is 68 r/min,angle of spring tooth with crank is 50°. Through comparative test and analysis,it was found that the miss rate and maximum acceleration of spring tooth decreased to 0.677% and 39 507.1 mm/s,compared with the original mechanism,the optimization is 13.5% and 21.8%.
