摘 要
油菜是當今世界上最主要的農(nóng)作物之一，因為其種植成本和管理成本都比較低，而單產(chǎn)量較高，經(jīng)濟收益又較大，因此在世界范圍內(nèi)被廣泛栽種。我國是油菜生產(chǎn)大國之一，由于從播種到收割這整個過程一直是以手工作業(yè)為主要形式，勞動強度大，條件惡劣，作業(yè)效率比較低，因此，研制專用的油菜聯(lián)合收割機就成為當務(wù)之急。
為了完成此次畢業(yè)設(shè)計，我們一組10人在老師的帶領(lǐng)下，共同努力，一起完成。而我主要負責的是雙圓筒篩及糧箱的設(shè)計。這個雙圓筒篩是一種清選裝置，它主要是為了改進其它的清選裝置而專門設(shè)計的。一般的清選裝置都是平的，利用其振動來達到清選的目的。我為了使振動消除，特意設(shè)計了雙圓筒篩這種效果較好的清選裝置。其動力由主電機提供，通過帶輪傳到軸上，再通過鏈輪使兩圓筒篩同向轉(zhuǎn)動。被清選下來的油菜籽會通過輸送攪龍裝置輸送至糧箱。糧箱最關(guān)鍵的設(shè)計是在出糧口。我用壓桿和彈簧設(shè)計了一個自動夾緊裝置，可以把蛇皮袋夾在上面讓其自動工作，以便于減輕工人的勞動強度。糧箱上還帶有扶手，供工人扶手用。在糧箱頂部專門設(shè)計了蓋子，避免雨水或雜物落入其中。

ABSTRACT
Rapeseed is one of the main economic crops in the world today, because its cultivation cost and management cost is lower, and single output is higher, economic benefits is bigger, is widely planted in the world. China is one of the biggest production of rapeseed, as from sowing to harvesting the whole process is manual work as the main form, the intensity of labor is high, the condition is bad, the efficiency is lower, therefore, to develop special of rape combine harvester has become the top priority.
In order to complete the graduation design, we under the guidance of the teacher, a group of 10 people joint effort, to complete together. And I am mainly responsible for double cylinder screen and food box design. The double drum screen is a kind of cleaning device, it is mainly to improve other cleaning device specially designed. General cleaning device are flat, with its vibration to reach the purpose of cleaning. I in order to eliminate the vibration, specially designed a double cylinder screen this effect better cleaning device. The power provided by the main motor, through the pulley to the shaft, and then through the sprocket makes the rotating drum screen. Cleaned off rapeseed will stir by transmission dragon device to food box. Grain tank is the most critical design in food outlet. I use a lever and spring to design an automatic clamping device, it can let the snakeskin bag clip above it work automatically, in order to reduce the labor intensity of workers. On the grain tank, there is a armrest for workers armrest. Specially designed on the top of the grain tank lid, avoid rain or sundries fall into one of them.
Key words: rapeseed;combine harvester;double cylinder screen;grain tank;design
