Optimization of working efficiency of rape crawler mower header in agricultural machinery cooperatives based on biomechanics
Abstract
This paper focuses on the optimization of operation efficiency of rape crawler mower header in Agricultural Machinery Cooperatives. In view of the important position of rape in agriculture and the problems existing in the cutting, conveying and laying of the existing windrower header, biomechanical methods were introduced. The working principle, structure and main parameters of the windrower are introduced in detail. The biomechanical analysis of the header operation process is carried out, and the key components such as reel, cutter and conveyor are designed and optimized. The header device frame topology is also optimized. The results showed that the first three natural frequencies of the header were increased after optimization, which effectively avoided the resonance risk, and the amplitudes of monitoring points in vibration test were significantly reduced, indicating that the optimization strategy was effective, which was of great significance to improve the efficiency and quality of rape harvest and promote the development of agricultural mechanization.
