一、主要工作部件型式的选择 (一)甜菜挖掘收获机的结构组成甜菜挖掘收获机的结构复杂程度各异,但概括说来,大致可分为四个主要工作部分,即挖掘部件、拣拾(清理部件)、清理输送系统、集箱装载系统。在每一组成部分中,又都有各种各样的型式。随着甜菜生产机械化的发展和研制水平的提高,世界各国都在努力探求新型的工作部件、以达到高性能、高可靠性的目的。目前世界各国甜菜挖掘收获机的结构组成及工作部件型式综合起来可用示意图(见图1)概述之。
First, the choice of the main working parts type (A) the structure of sugar beet mining harvester Sugar beet harvester structure of varying degrees of complexity, but in a nutshell, can be divided into four main parts of the mining parts, pick up (Cleaning parts), cleaning delivery system, header loading system. In each component, there are all kinds of patterns. With the development of mechanization of beet production and improvement of research and development level, all countries in the world are striving to find new type of working parts for high performance and high reliability. At present, the structure and composition of the sugar beet harvester in various countries in the world can be summarized as shown in Figure 1.
