摘要

    土豆作为人们的主要食品之一，具有丰富的营养价值，人们在日常生活中，人们都会围绕土豆来做出各种不同的菜肴，例如炒菜，炖汤等等。而通过刀具切削土豆片会很麻烦，如果有能够对土豆进行自动挖掘的机械，那样在一定程度上会大大提高挖掘效率和质量。

    该土豆挖掘机主要由机架、连接杆、摆臂、连接件、曲柄、抖动轮、挖掘铲、定位轴、地轮等等零部件组成。动力是通过拖拉机带动该土豆挖掘机在农田里面进行自动挖掘作业。该机效率高，产能好，适合批量挖掘土豆的场所。

Abstract

    potatoes as one of the main food of the people, with rich nutritional value, people in daily life, people will around the potato to make a variety of dishes, such as cooking, soup, and so on. And through the cutting tool cutting potato chips will be very troublesome, if there is to be able to peel the skin of the machine, then to a certain extent, will greatly improve the efficiency and quality of the peel.

    The potato peeler is through artificial potatoes into potato peeling machine barrel inside, at the bottom of the motor through the transmission gear to drive the transmission shaft to rotate, so as to drive the rotating body rotation, rotation body spot welding can be through the potatoes with a rotating body surface friction and skin small metal grinding, potatoes and with the rotary body to rotate together, and the inner wall of the cylinder body welding scraping knife, that comes with the rotation of the rotating body, the inside of the barrel body of potatoes has been constantly and the surface of a rotating body of small metal grinding blade and the inner wall of the barrel body scraping knife friction to the skin effect

Key words:Potato peeling machine,cutting tool,rotating body, peeling
