轻简式烟草打顶抑芽机控制系统研究

Study on Portable and Simple Control System of Tobacco Topping and Sucker Machine

随着烟草农业的不断发展,烟草打顶抑芽的工作成为提高烟叶产质的重要方式。在平原地区打顶抑芽机已经投入使用,而在山地丘陵地区,由于其独特的地形,并没有合适的小型机械进行打顶抑芽,为了提高烟草打顶抑芽的工作效率,在结合烟杆的结构特点以及人工打顶抑芽的工作步骤后,研制了一种小型的烟草打顶抑芽机。在介绍这种打顶抑芽机基本结构的基础上,对其控制系统进行研究。该系统采用无刷直流电机驱动药泵喷药,利用单片机控制准确地控制喷药量及其位置,保证工作的可靠性,同时对该控制系统喷药量的检测做了测试试验,验证了其喷药量的准确性。该设计提高了工作效率,实现了烟草打顶抑芽机的半自动化,进一步推动了烟草农业的现代化进程。

With the development of tobacco agriculture, the tobacco topping and sucker work has become an significant way to improve the yield I and quality of tobacc0. Topping machine had been put into use m plain area. While in the hilly and mountamous areas,there was no statable small machinery for top bud inhibition because of its unique terrain. In order to raise the efficiency of tobacco topping,Based on the structural eharaeteristies of the tohaeeo rod and the working procedures of manual topping,a small tohaeeo topping machine had been invented. Based on the intro- duction of the basic structure of the topping and bud cutting reaehine,the control system was studied. The system used albrushless DC motor to drive the pump spray, it Also used the SCM to control the quantity and position of spraying,which could ensure the reliability of work. Besides, the detection of the spraying amount of the control system was tested,and the accuracy of the spraying amount was verified. The design improved the efficiency of the machine and it has realized the semi automation of tobacco topping and promotes the modernization process of tohaeco agriculture.
