摘要:

在我国大力发展牧草收获机械的背景下,为适应内蒙古地区搂草作业地面环境复杂,减小机具运输占地面积,提高工作效率本文主要对BL-600型指盘式搂草机的整体结构、主要零部件弹齿进行了应力分析、连杆机构进行了设计,解决了机器运输体积大、不易掉头且弹齿容易变形和断裂等问题。分别采用Proe/Mechanica模块建模仿真等手段对弹齿的应力进行分析,根据仿真结果确定可靠有效的弹齿材料。通过对搂草运动的分析确定工作机具的结构和位置以及油缸的行程。进而提高了整体机具对工作环境的适应能力。同时,针对机具进行了试验验证,搂草机漏搂率为2%,达到设计要求,该机型性能稳定、具有较强的实用性和推广价值。

Abstract:

Under the background of vigorously developing herbage harvesting machinery in China, in order to adapt to the complex ground environment of grass rake operation in Inner Mongolia, reduce the transport area of machinery and tools, and improve work efficiency, the overall structure of BL-600 finger-disc rake and its main component of spring teeth with stress analysis and connecting rod mechanism are mainly carried out in this paper in order to solve the problems, such as large volume of machine transport, difficulty in turning around and easy deformation and breakage of spring teeth. Proe/Mechanica module modeling and simulation methods are used to analyze the stress of the spring teeth, so as that reliable and effective spring teeth materials are determined according to the simulation results. The structure and position of the working machine and the stroke of the oil cylinder are determined through the analysis of the motion of the grass rake. In addition, it improves the adaptability of the whole machine to the working environment. At the same time, the experiment verifies that the leakage rate of the rake is 2%, which meets the design requirement. Through experimental research, it is found that the model has stable performance, strong practicability, and promotion value.
