PAGE IV 切菜机的设计 摘 要 蔬菜是人体所必需的一种食品，而且食用方法多样。所以要把蔬菜加工成各种形状，如条状、片状等；单靠人工来完成既费时、费力而且也不好加工。目前，多功能切菜机多为价格昂贵的大型设备，不适用于农民个体生产及小型工厂的食品加工；为克服这种缺点，本设计在查阅了大量相关文献资料的基础上，进行切菜机的设计，经过理论计算及校核，设计了一种小型多功能切菜机。该机主要由进料斗、下料斗、切削刀、刀盘及电动机组成，其工作原理是利用根茎类蔬菜的自由落体实现进料，通过切削刀旋转将下料斗中的蔬菜进行切片或切丝，最后成品由出料口出料。实现了能够连续进料和出料，片厚度、丝粗细可调的功能，具有生产率高、功耗低、安全可靠、加工质量好等优点。 关键词：蔬菜，切削，电动机 DESIGN OF THE VEGETABLE CUTTING MACHINE Abstract Vegetables are essential food for our body, and we uaually make them in various ways. In the process of eating, the vegetables need to be made into a variety of shapes, such as strip, sheet and so on; It is time-consuming, laborious and it is not easy to cut the vegetables well when we only depend on human themselves. Currently, multi-functional shredders are mostly expensive and large, they do not apply to individual farmers or small factories which produce food; In order to overcome this drawback, the paper makes a design of a small multi-purpose shredder on the foundation of a lot of relevant literature on the conduct shredder design, and it is also through some theoretical calculations and checking. The shredder consists of a feed hopper, hopper, cutting knife, the knife dish and motor, and its working principle is to use the freefall of root vegetables to realize the feed, then through the cutting knife to make the vegetables to slice or shred. Finally, the finished product come out from the discharge port. It is able to achieve a continuous feed and discharge, and it also has a function to adjust the slice thickness, wire thickness. It is a product which is with high productivity, low power consumption, safe, reliable, good processing quality and other advantages.
