轻便自走式采茶机的设计与试验

Design and experiment on portable self-propelled tea picker

针对当前双人手抬式采茶机需要配置操作人员数量较多,使用舒适度差等问题,设计了一种适用于丘陵缓坡梯田式茶园的轻便自走式采茶机。分析了整机的结构及工作原理,对履带底盘、采茶升降机构、液压传动系统进行了理论分析和选型计算,开展了田间采茶试验,并对样机进行采茶质量性能测试。试验结果表明,该采茶机工作性能稳定,采下茶叶完整率为81.1%、可制茶率为93.7%、茶叶损失率为0.82%、漏采率为0.77%,各采摘性能指标均在标准范围以内,满足使用要求。

In order to solve the problems that the current double hand-lifted tea picker need to be equipped with a large number of operators and the use comfort was poor,a portable self-propelled tea picker suitable for hilly and gentle slope terraced tea gardens was investigated.Its basic structure and working principle of the whole machine were explained,and its key components such as crawler chassis,tea-picking lifting mechanism,hydraulic transmission system and so on were designed and analyzed.Field tea picking experiments were carried out to test the performance of the prototype.The results showed that the fresh leaves under the integrity was more than 81.1%,processable tea rate was more than 93.7%,measured tea machine loss rate was less than 0.82%,measured tea machine leakage rate was less than 0.77%.The portable self-propelled tea picker had a good performance,which meet the requirements of tea farmers for picking.
