马铃薯播种机具的设计
摘要马铃薯是我国主要的粮食作物之一，在我国得到大面积栽种。 年，我国马
铃薯种植面积和产量都位居世界首位，然而尽管总产量大，但是单产量却很低。造成这
一原因的主要因素是种植方式和机械化水平的落后。因此，当前的主要任务就是提高马
铃薯种植的单产量。提高马铃薯单产量有两个途径：一是改进种植方式；二是提高机械
化种植水平。而提高机械化生产水平是最有效的方式，这就要求各种性能先进，种植效
率高，通用性和适应性强，结构简单易于制造与维修的马铃薯种植机不断被设计出来并
得到大力的推广与应用。升运链式马铃薯播种机是一种块状马铃薯播种机，其结构简单，
工作可靠，效率高，不伤种，在国内外正逐渐得到广泛的应用。

The Design For The Ladle— chain dispenser of Potato
Abstract
Potato, which is one of the most important grain crops in our country, is
growthing in a rather huge area. In 2007, potato’s planting area and output of
China situated in the first place of the whole world. Although the ultimate output
is huge, the per unit area yield quantity is at a rather low palce. The tow primary
reasons for this situation are that we are behindhand in the way of planting and
in the mechanized level. Therefore, the currently primary mission is enhances
the per unit area yield quantity. Generally speaking,we could arrive at this aim
through two ways: First, improving the way to plant; Second, enhancing the
mechanized level of planting. At now, raising the mechanized production level is
the most effective way. This will request each kind of potato-planting machine
