4LB-0.7型半喂入联合收割机的振动控制与研究

4LB-0.7型半喂入水稻联合收割机具有体积小、重量轻、结构简单、稳定性高等优点,特别适合山区小田块水稻收割。该机采用的滑块式切割机构在作业时会产生较大的惯性力,从而引起收割机不断振动,甚至导致联合收割机不能正常工作,必须在曲柄上增加一定质量的配重以减少振动。通过对该机的切割机构进行动力学分析和研究,用三维直角坐标确定机构中各构件的位置,并建立曲柄、滑块、割刀的运动学模型,利用程序计算得到最优位置和最合理的配重质量,这样就可以解决振动问题。

Study on Vibration Control of 4LB-0.7 Semi-feed Combine

4LB-0.7 semi-feed rice combine is typical of little volume, light and simple structure, so it is appropriate for small mountainous fields. Because the machine adopts the slipper-type transmission system of cutter, strong inertial forces has been generated. Unceasing vibration can make the combine harvester unable to work. There must be decreases in vibration if the balance weight is added in crank. How to define the balance weight and position is the crux of removing vibration. Therefore, after the transmis...
