Abstract

To meet the requirements of tobacco topping and ensure the efficient removal of topped buds, leaves, and shoots from the field. A lightweight clamping conveyor device was designed through an analysis of the forces acting on critical components and their operational principles. A rigid-flexible coupling dynamic simulation of the tobacco top stalks clamping and conveying process was conducted using ADAMS. An orthogonal experiment with three factors (forward speed, clamping distance, and conveying speed) at three levels was performed, with clamping success rate and conveying success rate as evaluation indices. Field validation experiments showed that at a forward speed of 0.6 m/s, a clamping distance of 11 mm, and a conveying speed of 1.1 m/s, the average clamping success rate was 94.52%, and the average conveying success rate was 98.36%. The conveying process was stable, with a high collection rate of top stalk, demonstrating strong adaptability to agricultural practices and meeting the operational requirements of tobacco topping in the field.

为满足烟草智能化打顶将打下的花蕾、叶、芽等清出田间的需求，现有智能切割打顶装备需配套可随切割装置快速移动的轻型夹持输送装置，防止输送过程中出现割下烟草顶花掉落、堵塞等问题，本研究通过对装置关键部件的受力及作业原理分析，并采用ADAMS开展夹持输送过程刚柔耦合动力学仿真，以前进速度、夹持间距、输送速度为试验因素进行三因素三水平的正交试验，以夹持成功率、输送成功率为评价指标确定最优参数组合。田间验证试验表明：烟草打顶机前进速度为0.6 m/s，夹持间距为11 mm，输送速度为1.1 m/s时，平均夹持成功率为94.52%、平均输送成功率为98.36%，输送过程平稳、顶花收集率高，对种植农艺适应性好，满足烟草打顶的田间作业要求。
