驱动式马铃薯中耕机的设计与仿真分析

针对我国传统中耕机械存在的碎土效果不理想、易缠绕堵塞的特点,设计了一种驱动式马铃薯中耕机。该机能够一次性完成垄间松土、碎土、除草及培土等作业。对中耕机旋转单体中的碎土刀进行受力、刀的排列等分析,并通过ANSYS软件对旋转单体进行运动仿真。仿真结果总变形和等效应力验证了旋转单体的可靠性,证明了该机具可以实现深松、碎土等工作过程。机具结构设计合理,为中国北方等粘重土壤地区的中耕作业提供了技术支持,也为马铃薯中耕机的设计改进与优化提供了理论支撑和技术参考。

Design and Simulation Analysis of Driving-type Potato Cultivator

In this paper, aim at the characteristics of traditional soil tillage effect was not ideal and easy winding clogging. Designed a driving-type potato cultivator, the machine can complete ridge soil, broken soil, weeding, hill up soil and other works on one time. In this paper, the key components of the driving potato cultivator are designed and the rotating monomer was analyzed by ANSYS software. The simulation results which were total deformation figure and equivalent stress figure proved the machine was reliable and also showed the design was rational. It was proved the mechanical structure was reasonable and can realize the working process of loosening and crushing soil and other work process. It provided technical support for the cultivation of soil in the north of China. The study provides the important theoretical and technical reference for the improvement and optimization of the driven type potato cultivator.
