PAGE-23-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。关键词：窝眼筒，承种槽，螺旋输送器AbstractThisarticleintroducedthe5XW-15design,theprincipleofworkandtheimprovementprocess.Inthearticletochosetheprincipleandseed'shasconductedthethoroughresearchintubestressanalysisclear,tochosethequalityinfluencecleartheresearch.Afterthegraspingdesignmethod,carriesontheinnovationdesignintheoriginaltypefoundation,mainlyimprovesthemeasuretoinclude:Aroundtheidenticalnesteyetubeiscomposedby2parts,theprecedingpartofnesteyeusesinclearforthealveoluseyeshortmixed,thesecondhalfofnesteyeusesinclearforthebignesteyelongmixed,asthematterstandsunvoicedaspiratedconsonantselecttobepossiblelongmixedandshortmixedallremove.Moreoverisinisatenantfarmeroutsidethetroughtoinstallthespiralpiece,likethismaymixevenlytheseedwhichinthenesteyetubetreatselectsclear,alsomaycausetochooseaftertheseedbackwardtodischargeclear.Mainimprovementmeasureincludingnesteyesocketdesign,additionspiralpiece,nesteyetubeinnovationdesignandsoon.Keyword:Thenesteyetube,isatenantfarmerthetrough,spiralconveyor目录TOC\o"1-2"\h\z\uHYPERLINK\l"_Toc231305556"摘要PAGEREF_Toc231305556\hIHYPERLINK\l"_Toc231305557"1前言PAGEREF_Toc231305557\h-1-HYPERLINK\l"_Toc231305558"2设计方案PAGEREF_Toc231305558\h-7-HYPERLINK\l"_Toc231305559"2.1可行性分析PAGEREF_Toc231305559\h-9-HYPERLINK\l"_Toc231305560"2.2给料方法的设计PAGEREF_Toc231305560\h-9-HYPERLINK\l"_Toc231305561"2.3工艺流程PAGEREF_Toc231305561\h-9-HYPERLINK\l"_Toc231305562"3工作原理PAGEREF_Toc231305562\h-10-HYPERLINK\l"_Toc231305563"4主要参数的设计PAGEREF_Toc231305563\h-12-HYPERLINK\l"_Toc231305564"4.1初定窝眼筒的直径，长度，和转速PAGEREF_Toc231305564\h-12-HYPERLINK\l"_Toc231305565"4.2窝眼筒长度PAGEREF_Toc231305565\h-12-HYPERLINK\l
