摘要斗式提升机是专门用于连续垂直输送物料（物料可包括大米、玉米、小麦等粮食作物和其他散装物）的设备。其结构由下而上可分为3个部分，即底座部分、机筒部分和机头部分。斗式提升机一般由电机提供动力，其主要驱动装置为头轮，头轮则带动牵引构件运行，牵引构件上挂上料斗，并带动料斗和物料一起运行。物料通过人工或者机械的方式从机座的进料口进入机座底部，一部分直接进入料斗，一部分后被运动着的料斗挖起，通过头轮的驱动装置，垂直运输向上。斗式提升机的工作过程可分为进料阶段、提升阶段和出料阶段3个过程。物料到达机头后，在重力和离心力的共同作用下从料斗脱离，并带有一定的速度从出料口排出。斗式提升机具有良好的密封性、很小的占地面积、结构比较简单、效率较大(2～300t／h)和提升高度高(2080m)等优点，在饲料和粮食等散装物料加工厂中使用极为广泛。51163

    以往的斗式提升机的设计基本上是以CAD或者其他二维图表达，但通常用二维图来表达它的结构特征，比较抽象，二维图不直观，并且整个设计的产品也不便于后期的修改。本文以THD630型斗式提升机为原型，利用三维软件SolidWorks对斗式提升机的各个零件进行三维造型，然后对斗提机的机座部分、机头部分、中间部分分别进行虚拟装配，最后进行总虚拟装配。

    SolidWorks软件是世界上第一个基于Windows开发的三维软件系统，由于技术创新符合CAD技术的发展潮流和趋势，solidworks公司发展很快，在很短时间内迅速成为绘图软件巨头公司。Solidworks软件组件繁多，功能强大，很容易学习和使用，简单明了，是solidworks的几大特点。使用solidworks，这款软件的设计非常的灵活，通俗易懂，易学易用，整个产品设计可编辑化程度非常高，在产品的零件设计、单个或者整体装配设计和工程图之间是完全相关的，可用度非常好。

 ABSTRACT   Bucket type lifting machine is designed for continuous vertical transportation of materials (including rice, maize materials, wheat and other grain crops and other bulk) equipment. The structure of bottomup can be pided into 3 parts, namely the base part, barrel part and the head part. Bucket type lifting machine is powered by motor, the main driving device for the first round, the head wheel drives the traction component running, traction component hung hopper, and drives the hopper and a material run together. The material into the bottom of the base from the feed frame by artificial or mechanical means, one directly into the hopper, a hopper part after moving to dig through the driving device, the head wheel, vertical transportation to. Bucket type lifting machine working process can be pided into the feed phase, phase of ascension and the discharging stage 3 processes. The material reach the head, both gravity and centrifugal force from the lower hopper detachment, and with a certain speed from the discharge port. Bucket type lifting machine has good sealing, small occupation area, simple structure, high efficiency (2 ~ 300t / h) and high lifting height (2080m) and other advantages, in the feed and food and other bulk materials processing plant is the most widely used. The bucket elevator design basically is in CAD or other twodimensional graph expression, but usually with twodimensional graph to express the structure characteristics, it is more abstract, twodimensional map is not intuitive, and the design of the product is not easy to modify. Based on the THD630 type bucket elevator for the prototype, for the threedimensional modeling of the bucket type lifting all machine parts using threedimensional software SolidWorks, then the bucket seat part, the head part, middle part of virtual assembly, the general assembly. SolidWorks software is the world's first based on the threedimensional software Windows development system, due to the development trend of technology innovation in accordance with CAD technology and the trend of development, SolidWorks company quickly, quickly became the software giant, in a very short period of time. Solidworks software component is various, powerful, easy to learn and use, simple and clear, is the major characteristic of solidworks. The use of Solidworks, the design of the software is very flexible, userfriendly, easy to use, the product design can edit degree is very high, between the parts of product design, inpidual or whole assembly design and engineering drawings are fully correlated, availability is very good.
