摘　　要：高枝剪在果树修剪作业中具有较广的应用范围。为此,针对传统手握式高枝剪切断能力和操作等问题,设计试制了一种脚踏式高枝剪,主要由脚踏机构、传动机构和执行机构组成,依靠人体重力和腿的支撑提供压力,可切断较粗的枝条。通过与传统高枝剪效率和切断能力的对比试验,论证了脚踏式高枝剪具有切断较大直径枝条和适合较长时间连续作业的优点。针对试验中遇到的一些问题,利用TRIZ模型进行分析,探索进一步提升高枝剪性能的途径。Lopper has a wide range of application in fruit tree trimming.A pedaling lopper is designed in this paper to solve the problem in abscission limitation of traditional handling lopper.The lopper is composed of pedal mechanism,transmission mechanism and actuator mechanism.Boughs can be chopped by the force provided by weight of worker and foot sustentation.Through efficiency and cutting capacity comparison test of traditional lopper,the advantages of chopping big boughs and longer continuous operation time of the pedaling lopper in this paper is verified,and it is suitable in trimming fruit tree in mountainous and hills area.TRIZ analysis is utilized to solve some problem of test data and search for improved method of lopper performance.
