基于 Inventor 的免耕播种机组合式开沟器设计

摘要

Opener is one of key components to affect the seeding quality for no-till planter , which should be used to re-duce the destroyed soil as far as possible on the basis of meeting the agronomic conditions .The combined opener is de-signed to make the fertilizer and seeds with the vertical stratification in the same furrow , and the seeds lie above the fer-tilizer .The model of shovel handle , connected component parts and others are set up with Inventor .It can create a series of components using the software to realize the standard design because the shape of seeding tube and fertilizing tube of the combined opener are similar .A 3 D virtual assembly model of the combined opener is established , which can provide the research basic to establish the simulation model for dynamic analysis .%开沟器是免耕播种机影响播种质量的关键部件之一，在满足农艺条件的基础上应尽量减小开沟器的动土量。本组合式开沟器实施种肥同沟垂直分层分施，种子播在肥料的正上方。利用 Inventor 软件建立了铲柄、固接部件等零件模型，并创建了系列零件，实现了自行设计标准件。同时，建立了组合式开沟器三维虚拟装配模型，为动力学分析软件建立仿真模型提供基础。
