摘  要:
针对4LBZ–125型半喂入水稻联合收割机割台存在输送不畅的问题,设计了以该收割机割台为原型的室内试验台,以输送效果、切割效果、扶禾效果和其他效果等为评价依据,对割台扶禾速度、切割速度、输送速度和机器行走速度等进行了正交试验和单因素试验。正交试验结果表明,影响割台性能的主要因素是行走速度和输送速度;单因素试验结果表明,割台正常工作最佳参数为扶禾速度0.8 m/s、切割速度0.85 m/s、输送速度1.1 m/s、行走速度0.675 m/s。对正交试验结果较佳组合和单因素最佳参数组合进行验证对比试验,结果表明,单因素最佳参数组合输送效果最好,能较好地满足生产要求。

摘  要:
Cutting table blocking is one of the common and serious problems for 4LBZ–125 head-feed rice combine.To improve it,an indoor test-bed based on this combine is designed.Taking the comprehensive score as evaluation indicator,the orthogonal and single factor tests were done on crop-lifting speed,cutting speed,transmission speed and walking speed of the machine.The orthogonal test showed that the walking speed and transmission speed had great influence on header performance.And the single factor test showed that the best speed parameter for crop lifting,cutting,transmission and machine walking is 0.8 m/s,0.85 m/s,1.1 m/s and 0.675 m/s,respectively.Validation and contrast tests were done between the combination of orthogonal test and the best parameter combination of single factor test.The result showed that the single factor parameter combination had the best transmission efficiency and satisfied the production requirements.
