土豆切丝机的设计

摘要

近几年来，随着国内外土豆丝市场需求量的不断增加，我国一些地方也相继对土豆切丝机械化方面进行一些研究。目前，我国土豆丝的加工仍然采用半自动化或人工的方法。这种加工方法既浪费大量的人力、物力，而且在操作过程中也存在极大的安全隐患，并且劳动强度大，生产效率低，加工的土豆丝不均匀。为此，本文研究一种成本低，结构简单，操作方便，省时、省力、安全、生产率高的土豆切丝机。

土豆是人体所必需的一种食品，而且食用方法多样。所以要把土豆加工成各种形状（如：条状、片状等等），单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，我查阅了大量相关的文献资料，通过对各种小型切菜机性能的分析及比较，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、切削刀及刀片、及动力源――电动机组成，工作原理主要是利用土豆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、切丝，最后成品由出料口出料。该机将原有的多功能切菜机进行了优化设计，实现了能够连续进料和出料，片厚度、丝粗细调的功能，具有生产率高、功耗低、安全可靠、加工质量好等优点。

Abstract

In recent years, with the increasing demand for domestic and international potato market, and some places in China have also shredded potato mechanization some research. At present, China's potato processing still using manual or semi-automated methods. This processing method not only waste a lot of manpower and material resources, but also during operation, there are also a great security risk, and labor-intensive, low productivity, and processing of potatoes wire uneven.

To this end, this paper Study of a low cost, simple structure, easy to operate, saving time, effort, safe, highly productive potato cutters.

Potatoes are a food necessary for the body, and eating methods varied. So should the potatoes processed into various shapes (eg: strip, sheet, etc.), simply rely on manual to complete time-consuming, laborious process and is not good. At present, multi-functional Shredder mostly expensive large equipment, the production does not apply to individual farmers and small food processing plants; To overcome this disadvantage, I looked up a number of related documents, through a variety of small vegetable analysis and comparison of machine performance, through theoretical calculations and checking, designed a small multi-purpose shredder. It consists of a hopper, under the hopper, cutting knives and blades, and power source - electric motor, the working principle is the use of feed potatoes freefall realized by rotating the cutting blade under the hopper slicing vegetables, shredded, the final product from the discharge port discharge. The original multifunction machine Shredder optimized design, implementation, and can continuously feed the material, thickness, the thickness of the wire transfer function, high productivity, low power consumption, safe, reliable, good processing quality, etc. advantage.
