香蕉秸稈/根茬還田機(主傳動、粉碎機構設計)
摘 要
機械工業(yè)為國民經(jīng)濟提供裝備和為人民生活提供耐用消費品的生產(chǎn)。我國是一個農(nóng)業(yè)大國，農(nóng)業(yè)機械化程度的高低反映我國農(nóng)業(yè)生產(chǎn)發(fā)展的程度，雖然農(nóng)業(yè)機械也占有大量市場，但專業(yè)現(xiàn)代化的不多。故我們針對香蕉種植市場設計了一種高效、復式作業(yè)工具。
這次的設計針對香蕉秸稈/根茬還田機的還田系統(tǒng)，主要設計了它的主動系統(tǒng)，根據(jù)設計要求它的主傳動系統(tǒng)動力主要有拖拉機的后置動力供給，要求供給的動力為兩路輸出：一路經(jīng)由換向提供給粉碎機構，需要具有良好的平衡性。另一路經(jīng)由換向減速器提供給除根還田裝置。為了達到設計要求，設計一系列齒輪、軸等零件的參數(shù)并對其進行校核。其次是它的秸稈粉碎機構，根據(jù)需要設計它的刀片為兩個直刀片，裝在刀柄的兩端，通過主傳動軸傳送過來的動力使刀柄高速旋轉，從而將香蕉秸稈粉碎。
該設計產(chǎn)品結構合理，緊湊。操作方面，使用性能可靠，通用化程度高。其性能指標達到國內領先水平。一舉實現(xiàn)了真正的復式作業(yè)，為種植戶節(jié)省了大量的資源，提高了生產(chǎn)效率。深受用戶歡迎，從而為我國的香蕉種植業(yè)的發(fā)展拓展了前景。

THE MACHINE FOR BANANA
STRAW/ROOT REUSE (DESIGN OF THE MAIN TRANSMISSION SYSTEM AND THE SMASH INSTALLATION)
ABSTRACT
Mechanical industry offers equipment and the production that offers durable consumer goods for people's life for national economy. Our country is a agricultural large country, the difference in degree of the degree of mechanization of farming reflects the degree that the agricultural production of our country develops , though agricultural machinery also possesses plenty of markets, but special field is modern seldom. So, we have designed a kind of efficient, compound schoolwork tool aimed at banana planting market.
When aiming at banana in the design straw stalk / root Cha return field machine return field system, basis and the active system especially it need to design its main transmission system after have tractor put power supply 。The power that design asks to provide is exported for two roads: Offer all the way via inverting to give to smash installation , need to have good balancedness. Another road offers via inverting gear reducer to give to root out return field installation. To reach design requirement , design the parameter of the elements such as a series of gear and axle and carry out school for it, it is nuclear. Secondly is its straw stalk smashes installation, design its blade according to needs for two straight blades , pack the two ends in knife handle , make the high speed of knife handle revolving through the power that main power transmission shaft delivers , so smash banana straw stalk.
This design product mix is reasonable, compact. Operating aspect and the reliable, generalization degree of performance characteristics are high. Its performance index reaches domestic leading level. Have realized genuine compound schoolwork instantly , have saved plenty of resources for planting household , have raised production efficiency. Is welcomed deeply by user , so have extended prospect for the development of the banana planting field of our country.
KEY WORDS：Main transmission system, smash installation, gear, axle, blade
