摘　　要：为解决人工采摘菠萝劳动强度大、采摘困难、效率低的问题,设计了一种基于曲柄滑块、偏置直动滑杆与多连杆传动式机构的菠萝采摘装置。运用Adams对机构运动进行仿真分析,优化了装置各部件的参数。实物样机经过实际测试,结果表明,装置适用于茎径为3~6 cm的菠萝采摘。试验统计数据表明,该装置单次采摘用时比人工采摘平均减少1.2 s,提高效率26%,同时也验证了装置运动的平稳性以及刀具切割的稳定性。In order to solve the problems of high labor intensity,difficulty in picking,and low efficiency of manual pineapple picking,a pineapple picking device based on crank slider,offset linear sliding rod and multi link transmission mechanism is designed.The Adams is used to simulate and analyze the movement of the mecha⁃nism,and the parameters of each component of the device are optimized.The actual prototype has been tested,and the results show that the device is suitable for picking pineapples with a stem diameter of 3-6 cm.The test statistics show that the single picking time of the device is 1.2 s less than manual picking,and the efficiency is increased by 26%.The stationary motion of the device and the cutting stability of the tool are also verified.
