摘要
目前，農(nóng)作物秸稈及牧草類(lèi)等粗纖維物料粉碎加工多采用普通粉碎機(jī)，效率低，能耗高，不能達(dá)到粉碎要求，市場(chǎng)上也沒(méi)有專(zhuān)業(yè)的加工機(jī)械產(chǎn)品面世，因此研制秸稈和牧草等物料加工機(jī)械存在著客觀的必要性。為此，主要介紹了秸稈類(lèi)粉碎機(jī)的設(shè)計(jì)思想、設(shè)計(jì)方案、主要零部件的設(shè)計(jì)要點(diǎn)、性能參數(shù)的確定以及本機(jī)的工作原理。
針對(duì)現(xiàn)有玉米秸稈加工機(jī)械加工時(shí)的秸稈水分、營(yíng)養(yǎng)成分流失嚴(yán)重等問(wèn)題，設(shè)計(jì)出了一種采用三維切割方式的青玉米秸稈粉碎機(jī)，介紹該粉碎機(jī)的主要結(jié)構(gòu)和設(shè)計(jì)參數(shù)。研究新型玉米秸稈粉碎機(jī)械，解決在工作原理及性能、尺寸參數(shù)、材料等方面的問(wèn)題，以達(dá)到對(duì)青狀玉米秸稈類(lèi)物料的加工利用，解決成本低與生產(chǎn)率高的矛盾，保證粉粒尺寸滿(mǎn)足實(shí)際生產(chǎn)的需要，為我國(guó)農(nóng)村，農(nóng)業(yè)的發(fā)展提供技術(shù)支持。玉米秸稈粉碎機(jī)可有力的促進(jìn)農(nóng)牧產(chǎn)業(yè)的發(fā)展，使農(nóng)副產(chǎn)品變廢為寶。

Abstract
Currently, etc. Straw and forage crude fiber material crushing mill processed more than ordinary , low efficiency, high energy consumption, can not meet the requirements crush on the market and no specialized processing machinery products available, and therefore the development of materials such as straw and forage processing machinery exists an objective necessity . For this purpose, mainly introduced to determine the straw shredder design ideas, design, design elements of the main components , the performance parameters and the working principle of the machine.
For existing moisture corn stalk straw processing machinery processing time , the loss of nutrients and serious problem , devised a way of using three-dimensional green corn stalks cut shredders, describes the main structure and design parameters of the mill . Research new corn stalks crushing machinery to solve problems in the working principle and performance, size parameters , materials, etc. , in order to achieve the green corn stalk -like processing and utilization of materials , to resolve conflicts with high productivity and low cost , to ensure silt size to meet the actual production needs , provide technical support for the development of rural areas, agriculture. Corn stalk shredders can effectively promote the development of agriculture and animal husbandry industries, so that agricultural waste into treasure .
Key words: Green corn stalks; grinder; dimensional cutting
