纵轴流式水稻联合收割机清选系统结构设计
摘要:水稻是我国的主要粮食作物,具有单产量最高,总产量最稳定的特点;近些年水稻种植面积处于稳步上升的状态。在目前水稻收获机械多种形式并存条件下,为了满足广大用户的要求,在消化吸收国内外同类机型的基础上,设计一种清选装置。本文简述了国内、外联合收割机的研究现状和典型清选装置的工作原理。通过查阅资料了解水稻的农艺、形态参数。通过对比,选择单风机双层振动筛清选装置,此种装置结构相对简单,但基本能满足此种收割机清选功能的要求。
本课题的研究为指导实际生产,提高轴流清选装置的性能以及降低成本提供了理论依据。

The Structure Design of Vertical Type Axial Flow bine Harvester Cleaning System
Abstract: Rice is our country's main food crop, have the highest single output of the most stable, output characteristic; The rice planting area in recent years has steadily risen state. In the current rice harvest machinery various forms to coexist conditions, in order to satisfy the demand of users, digesting and absorbing the basis of domestic and foreign similar type, design a kind of cleaning device. This paper describes the working principle of domestic and outside bine harvester Research and typical cleaning device. Through access to information to understand rice agronomic, morphological contrast, select a single fan double vibrating screen cleaning device, such device structure is relatively simple, but can basically meet the functional requirements of such a harvester cleaning.
The study of the subject to guide the actual production, improve the performance of the axial cleaning device as well as reduce the cost of providing a theoretical basis.
Key words: Rice ;Vertically mounted axial ;Cleaning ;Theoretical basis
