Design of an Portable and High Altitude Walnut Picking Machine
摘要
Abstract
In order to solve the problems of the operational, security and the poor mechanization of the walnut picking work, we developed a multifunctional walnut picking equipment which adapt to the mountain area that the trucks unable to enter. In this paper, we present the design scheme of the prototype for the machine, and give the design parameters for the key parts like telescopic rod and picking mechanism . The finite element modal analysis of the picking rod was de-veloped using the software ABAQUS, the modal figure and first 6 nature frequency of the model was achieved. The re-sults indicated that, the 1-2(54. 1-55. 2Hz) modal frequency mainly performance as overall vibration of the pick rod, 3-6(107. 3-184. 3Hz) modal frequency performance as vibration and torsional vibration of the pick rod parts though dif-ferent directions. The research would help to described the vibration characteristics of the system and could be referred by the similar study in order to improve the working performance.关键词
