一种芦笋采摘机机械手的设计

为了实现芦笋机械化采摘,降低人工劳动强度,提高芦笋种植经济效益,设计了一种小型芦笋采摘机,重点对采摘机构和三轴运行机构进行了设计、计算和分析。通过计算,确定了X/Y/Z进给机构丝杠的选型,并对其受力和刚度进行校核；同时对采摘机械手的结构进行了设计,确定了采摘机械手的尺寸,液压缸的行进距离,并对其关键零部件进行仿真分析,结果表明设计强度均满足要求。按照实际工作状况,对关键零部件进行三位建模,进行模拟组装后最终建立整机的三维模型。芦笋采摘机在劳动强度大的蔬菜采收环节能够大幅降低人工成本,在农村劳动力老龄化问题日益突出的情况下,具有一定的市场前景。

Design of a Robot for Asparagus Picking Machine

In order to achieve mechanized harvesting of asparagus, reduce manual labor intensity, and improve the economic benefits of asparagus planting, a small asparagus harvesting machine was designed, with a focus on the design, calculation, and analysis of the harvesting mechanism and three-axis operating mechanism. Through calculation, the selection of the X/Y/Z feed mechanism lead screw was determined, and its force and stiffness were checked; At the same time, the structure of the picking manipulator was designed, and the size of the picking manipulator, the travel distance of the hydraulic cylinder, and the key components were simulated and analyzed. The results showed that the design strength met the requirements. According to the actual working conditions, perform three-dimensional modeling of key components, simulate assembly, and ultimately establish a three-dimensional model of the entire machine. The asparagus picker can significantly reduce labor costs in the labor-intensive vegetable harvesting process, and has certain market prospects in the increasingly prominent issue of aging rural labor force.
