I摘 要本設計是根據(jù)國內(nèi)外播種機的發(fā)展趨勢，通用性和適應性不斷提高，根據(jù)大壟雙行播種形式而設計的一種能同時完成播種施肥工作的大壟雙行精密播種機。該機結構上優(yōu)點，使之能適應各種田地的播種。不管是平壩、還是淺丘地區(qū)；無論是板結的土質(zhì)，還是疏松的土質(zhì)都能適應。還可以根據(jù)用戶的不同需求，配置合適的播種器。通過調(diào)節(jié)犁鏵和種子儲存孔的行距，能夠輕松地播種小麥、大麥、高粱、大豆、玉米等旱糧作物。本例著重對播種機排種器、排肥器、開溝器、覆土器以及鎮(zhèn)壓輪等結構進行設計選擇。關鍵詞: 精密播種;播種機;大壟雙行;IIAbstractThe design is based on the development trend of domestic and foreign seeder,interoperability and adaptability in a constantly improving, big ridge a can complete seeding and fertilizing work also designed according to the double rowplanting form of double row precision seeder. The structural advantages, so that it can adapt to various fields of sowing. No matter is Pingba, hilly areas or; bothcompaction of soil, or loose soil can adapt. Also can be according to the different needs of users, the suitable seeding device configuration. By adjusting the ploughand seed storage hole spacing, can easily sow wheat, barley, sorghum, soybean,corn and other crops. This example focuses on the seed metering device, a fertilizer discharging device, a furrow opener, cover and press wheel structuredesign.Keywords：Precision seeding;Seeder;Double row;黑龍江八一農(nóng)墾大學畢業(yè)論文（設計）- 1 -目 錄摘 要 .IAbstract II1 前言 .- 1 -1.1 我國精密播種機發(fā)展現(xiàn)狀 .- 1 -1.2 精密播種機的發(fā)展前景 .- 1 -1.3 播種機類型 .- 2 -2 播種機的總體方案設計 - 3 -2.1 主要結構及功能 - 3 -2.2 總體配置 - 3 -2.3 播種機主要部件設計 .- 6 -2.4 傳動系統(tǒng) - 27 -3 播種機的使用注意事項 - 29 -3.1 播種機的保養(yǎng)與保管 .- 29 -3.2 安全準則 .- 29 -3.3 故障與排除 .- 30 -結 論 .- 31 -參考文獻 .- 32 -致 謝 .- 33 -
