摘  要

通常利用農(nóng)作物秸稈顆粒成型技術(shù)，把那些松散細(xì)碎或者無定型的秸稈擠壓成為形狀規(guī)則且又質(zhì)地緊密的成型燃料，這統(tǒng)稱為秸稈壓縮。當(dāng)秸稈擠壓成為顆粒后，它的能量密度大幅提升，燃燒特性會(huì)較成型之前有大幅改善。秸稈批量生產(chǎn)的重點(diǎn)是有性能優(yōu)越的秸稈壓縮機(jī)。首先，秸稈壓縮的產(chǎn)量主要由秸稈成型機(jī)的顆粒效率決定。再者，壓縮成本的增高是由成型機(jī)能耗過多造成的。因此，秸稈顆粒成型行業(yè)的首要課題是新型秸稈成型技術(shù)和設(shè)備的研究和發(fā)展。本文的設(shè)計(jì)內(nèi)容為研究秸稈顆粒成型機(jī)在國(guó)內(nèi)外應(yīng)用的現(xiàn)狀。根據(jù)研究結(jié)果，仔細(xì)分析比較現(xiàn)有的顆粒成型機(jī)，采納不同結(jié)構(gòu)的優(yōu)點(diǎn)，再設(shè)計(jì)成型機(jī)的最佳方案。確定最佳設(shè)計(jì)方案后，對(duì)重要部件如：軸承、電動(dòng)機(jī)、減速器、連接軸等進(jìn)行計(jì)算并選型，再對(duì)其進(jìn)行應(yīng)力校核。運(yùn)用Solidworks對(duì)秸稈顆粒成型機(jī)進(jìn)行三維建模是本次工作的最后一步。本次設(shè)計(jì)的農(nóng)作物秸稈顆粒成型機(jī)體積小，能使廢棄的資源得到合理利用并能創(chuàng)造經(jīng)濟(jì)利益，而且操作非常簡(jiǎn)單，能夠更多的運(yùn)用到日常生活中，最后他的維護(hù)成本也是極低的。

Structure Design of Grain Forming Machine Straw

Abstract

. Usually the use of crop straw particle molding technology, those loose or broken straw or extruded into a regular shape and compact texture of the molding of fuel, which collectively referred to as straw compression. When the straw is extruded into particles, its energy density is greatly improved, and the combustion characteristics are significantly improved before molding.. First, the yield of straw compression is determined primarily by the particle efficiency of the straw molding machine.Therefore, the straw pellet molding industry's top priority is the new straw molding technology and equipment research and development. The design of this paper is to study the application status of straw granulator at home and abroad. According to the results of the study, careful analysis of the existing particle molding machine, the advantages of different structures, and then design the best molding machine. Determine the best design, the important parts such as: bearings, motors, reducer, connecting shaft, etc. to calculate and select, and then its stress check. The use of Solidworks on the straw particle molding machine for three-dimensional modeling is the last step in this work. The design of the crop straw particle molding machine small size, can make the waste of resources to be rational use and can create economic benefits, and the operation is very simple, can be more applied to daily life, and finally his maintenance costs are very low.
