畢業(yè)設計說明書（論文）中文摘要
　　　
　　　本次畢業(yè)設計在仔細分析研究當前通用的幾種播種機的結構方案的基礎上，把握住其發(fā)展趨勢，力求設計研制出一種符合農藝要求，適合河北地區(qū)使用的性價比較高的新型精密播種機。該機可與12-20馬力小四輪拖拉機配套使用，適用于各種土壤條件，可以播種棉花、玉米、花生、大豆及小雜糧等，能一次完成刮平、開溝、施肥、澆水、播種、覆土鎮(zhèn)壓、噴灑除草劑、鋪膜及間隔填土壓膜等多項作業(yè)。為提高穴播質量，該機擬采用地輪滾筒連體舀勺式精量穴播排種器。地輪設計為變徑式，且能在軸上定向移動，用來改變穴距和行距，同時開溝器深度可調。本次畢業(yè)設計對整機方案進行研究設計，并重點對施肥和灑水系統(tǒng)進行設計計算。施肥系統(tǒng)由肥箱、排肥軸、傳動鏈輪和輸肥管等組成。外槽輪式排肥器將肥料送入輸肥管，經(jīng)開溝器進入土壤。灑水系統(tǒng)由水箱、傳動鏈輪、穴灌器、閥門和操作機構等組成。每隔一段距離，穴灌器打開，完成灑水動作。改變施肥系統(tǒng)和灑水系統(tǒng)傳動鏈輪的傳動比，可以改變排肥量和灑水的間距。

關鍵詞：播種機、整機設計、施肥器、澆水器

Title Main construction in multi-function sowing machine and water to apply fertilizer the system design

Abstract
The summary , this graduation project , is on the basis of analysing and researching the structure schemes of present several kinds of precise sowing machines in common use carefully, get hold of its development trend, make every effort to design and develop a kind of complex agronomy to require, new-type accurate seeder with higher price suitable for area of He bei to use. This machine can form a complete set and use in 12-20 horse powers of four small tractors , is suitable for various kinds of soil conditions , can sow the cotton , maize, peanut, soybeans accumulate the young food grains other than rice and wheat to wait, can one is it wipe off , ditch , apply fertilizer , water , seed , cover soil not to suppress , spray weed killer , spread membrane and interval fill out soil pigeonhole such large items of homework as membrane ,etc. to finish. For improving bunch planting quality, this machine plan not adopting connect rounds of cylinder with there aren't body. Ground wheel design for turn foot-path type into, and can orientation move at axle, is it change cave distance and row spacing to used for, at the same time the depth of the ditching device is adjustable. Graduation project this carry on research design by scheme to complete machine, and especially to apply fertilizer and sprinkle water the system not to is it is it calculate to design to go on. Apply fertilizer system by fat case , is it plant axle , drive sprocket and fail fat to is it make up to in charge of etc. to arrange. Fertilizer is it plant by whirling other trough expectation through fail fat to in charge of , enter soil by person who ditch to arrange while being wheeled. The system is made up by water tank , drive sprocket , cave irritating device , the valve and operating organization ,etc. to sprinkle water. Every other section from, cave irritating device turn on, it is for movement not to finish. It change apply fertilizer system it and can't sprinkle water systematic transmission of drive sprocket of than, can change not for quantity and the interval that sprinkle water not fatting.

Key Words: Seeder , complete machine are designed, Apply fertilizer the machine , Sprinkler .
