Camellia tea by reclamation after loose soil, fertilizer and water conservation, the promotion of tea plant root development, spring hair shoot number, shoot length, leaf number, new flower bud number were less than48.5%,118.7% increase in the county,88,11.5% and7%, and the tea seed weight increased by 0.73.3kg, yield increase11.739.2 kilograms, increase production 15.7%81.6%. The so-called reclamation is plowed barren mountain, its purpose is: to eliminate weeds shrubs, to promote soil weathering, therefore suitable for deep. Reclamation of depth depending on the situation, general 7 ~8 inch. The subject of the use of mapping software on Camellia tea cultivating machine intermediate transmission mechanism design, including the intermediate drive, side drive, rotary shovel design. Through the worm gear turning to power side, using the size gear speed reducing unit to the cutter, which solves the side driving the tilling amplitude is smaller, but also to achieve a low, efficient reclamation requirements.Keywords: tea, cultivating machine, an intermediate transmission, designIV目錄１ 緒　 論 ..............................................................................................................................11.1 　 引 言 ...........................................................................................................................11.2　 油茶墾復(fù)的簡(jiǎn)介 .........................................................................................................1２油茶墾復(fù)機(jī)的工作原理 ......................................................................................................22.1　 油茶墾復(fù)機(jī)的工作方式 ..............................................22.2　 油茶墾復(fù)機(jī)傳動(dòng)的選擇 ..............................................22.3　 油茶墾復(fù)機(jī)的耕作機(jī)具的選擇 ........................................22.4 油茶墾復(fù)機(jī)的工作原理的總圖 ........................................32.4.1 油茶墾復(fù)機(jī)工作原理簡(jiǎn)述 .........................................32.4.2 油茶墾復(fù)機(jī)的三維裝配圖 .........................................42.4.3　 油茶墾復(fù)機(jī)的傳動(dòng)機(jī)構(gòu)的二維圖 ..................................52.5 油茶墾復(fù)機(jī)的耕作機(jī)具 ...............................................62.5.1 旋耕刀的部分原理圖 .............................................62.5.2 旋耕刀的部分原理說(shuō)明 ...........................................63 油茶墾復(fù)機(jī)中間傳動(dòng)的設(shè)計(jì) ...............................................73.1 傳動(dòng)機(jī)構(gòu)的設(shè)計(jì) ............................................................................................................73.1.1 中間傳動(dòng)機(jī)構(gòu)簡(jiǎn)圖 .................................................................................................73.1.2 中間傳動(dòng)系統(tǒng)部分的原理簡(jiǎn)述 .............................................................................73.1.3 旋耕鍬的技術(shù)參數(shù) .................................................................................................73.2 傳動(dòng)比的確定 ................................................................................................................83.3 齒輪的設(shè)計(jì) ....................................................................................................................83.3.1 錐齒輪的基本幾何尺寸 .........................................................................................83.3.2 直齒圓柱齒輪的的設(shè)計(jì) .........................................................................................83.4 傳動(dòng)軸的設(shè)計(jì) .............................................................................................................113.4.2 初步計(jì)算軸上各段長(zhǎng)度 ....................................................................................113.4.3 軸的結(jié)構(gòu)設(shè)計(jì)： ................................................................................................113.4.4.繪制軸的彎扭矩圖，對(duì)危險(xiǎn)截面進(jìn)行校核 .......................................................123.5 軸承的校核 .................................................................................................................143.5.1 計(jì)算軸承的當(dāng)量動(dòng)載荷 P： ...............................................................................143.5.2 校核計(jì)算 ..............................................................................................................143.5.3 軸上鍵連接的選擇及校核 ................................................................................153.5.4 軸上螺母的選擇 ...................................................................................................153.6 懸掛機(jī)構(gòu)的設(shè)計(jì) ..........................................................................................................163.7 耕作機(jī)具的設(shè)計(jì) .........................................................................................................18４總結(jié) ..................................................................19參 考 文 獻(xiàn) .............................................................20致謝 ....................................................................21
