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.
