设计简介
摘要
本文介绍了5XW-15的设计，工作原理及其改进过程。文中对清选原理和种子在筒内的受力分析进行了深入研究，对清选质量影响的研究。掌握设计方法后，在原有机型的基础上进行创新设计，主要改进措施包括：同一个窝眼筒前后由2部分组成，前一部分窝眼为小窝眼用于清短杂，后半部分窝眼为大窝眼用于清长杂，这样一来一次清选就可把长杂和短杂都去除。另外是在承种槽外安装螺旋片，这样可以搅匀窝眼筒内待清选的种子，又可以使清选后的种子向后排出。主要改进措施包括窝眼孔型的设计，加装螺旋片，窝眼筒的创新设计等。

Abstract
This article introduced the 5XW-15 design, the principle of work and the improvement process.In the article to chose the principle and seed's has conducted the thorough research in tube stress analysis clear, to chose the quality influence clear the research.After the grasping design method, carries on the innovation design in the original type foundation, mainly improves the measure to include: Around the identical nest eye tube is composed by 2 parts, the preceding part of nest eye uses in clear for the alveolus eye short mixed, the second half of nest eye uses in clear for the big nest eye long mixed, as the matter stands unvoiced aspirated consonants elect to be possible long mixed and short mixed all remove.Moreover is in is a tenant farmer outside the trough to install the spiral piece, like this may mix evenly the seed which in the nest eye tube treats elects clear, also may cause to choose after the seed backward to discharge clear.
Main improvement measure including nest eye socket design, addition spiral piece, nest eye tube innovation design and so on.
Key word: The nest eye tube, is a tenant farmer the trough, spiral conveyor
