According to the needs of the actual production, on the premise of meeting the reqirement of precise seed sowing, the cost should be cut down and the speed increased. The precision planting provides accurate amount of seeds to soil at equal interval within rows and seeding depth. This planter is mainly comprised of the aperture-mould metering-device, fertilizer-carried pipe, seeds-carried pipe, double disics opener, covering and suppressing device; it is a complicated process comprising of ditching, fertilizing, planting, covering and suppressing; the requirements of its field performance are quite strict; it is designed to be 2 rows planter to improve its work speed and double discs opener is adopted, which ditches oderly, runs stably, and can be suitable for high speed. It has the characreristics of compact structure, simple transmission and riable performance, can sow different kind of seeds, such as maize, soybeans. Combined with fertilizing device, the planter can be designed to sow seeds and fertilizer at the same time. The planter has a widespread prospect of application. This article introduced the system of the fast and precise seed sowing machine. Its principle is the following: as the plater runs, the fertilizing disc turns to ditch, and the soil-wheel runs and drives fertilizer-drain shaft rotates via chains transmission; the fertilizer discharged by the box is fertilized into the soil; double disics opener turns and ditches with certain depth through depth-limited wheel; ditches-pressing blades enlarge the ditches; the seeds discharged by metering-device arrive at the ditches through seeds-carried pipe; and the suppressing V-wheel behind suppress the soil into the ditches with seeds and cover it with the soil at the same time. Thus, the requirement of precision planting has been completed.Key words：Seed; Aperture-mould Metering-device; Double Disics Opener; Suppressing V-wheel; Depth-limited Wheel目錄摘    要1ABSTRACT2第1章第1章緒  論51.1概述51.1.1 國(guó)內(nèi)播種機(jī)發(fā)展現(xiàn)狀51.1.2國(guó)外播種機(jī)發(fā)展現(xiàn)狀71.1.3種作業(yè)發(fā)展趨勢(shì)81.2播種方法91.3快速精密播種機(jī)的研究意義10第2章播種機(jī)總體方案確定112.1 播種機(jī)的設(shè)計(jì)依據(jù)與技術(shù)分析112.1.1 可行性分析112.1.2 農(nóng)藝技術(shù)指標(biāo)122.1.3 配套技術(shù)指標(biāo)122.1.4 技術(shù)經(jīng)濟(jì)指標(biāo)122.2 總體設(shè)計(jì)132.2.1 工作原理及結(jié)構(gòu)形式132.2.2 總體參數(shù)設(shè)計(jì)132.2.3 播種機(jī)的總體設(shè)計(jì)方案142.3 本章小結(jié)15第3章零部件設(shè)計(jì)計(jì)算及安裝153.1傳動(dòng)系統(tǒng)設(shè)計(jì)153.2種肥箱設(shè)計(jì)203.3排肥器設(shè)計(jì)213.4排種器設(shè)計(jì)223.5排種軸設(shè)計(jì)253.6塔輪鏈傳動(dòng)設(shè)計(jì)293.7其他工作部件的確定313.7.1施肥圓盤(pán)裝配313.7.2開(kāi)溝部件313.7.3仿形機(jī)構(gòu)333.7.4鎮(zhèn)壓裝置343.7.5支承輪裝配343.7.6機(jī)架總成353.7.7播種單體裝配353.8部件的安裝363.9播種前的準(zhǔn)備373.10本章小結(jié)40第4章播種機(jī)的使用維護(hù)和保養(yǎng)414.1播種機(jī)的使用414.1.1農(nóng)藝技術(shù)要求414.1.2播種的農(nóng)業(yè)技術(shù)要求414.2播種機(jī)的維護(hù)和保養(yǎng)424.2.1注意事項(xiàng)424.2.2維護(hù)和保養(yǎng)434.3本章小結(jié)44結(jié)  論45參考文獻(xiàn)46致  謝47【詳情如下】【需要咨詢購(gòu)買(mǎi)全套設(shè)計(jì)請(qǐng)加QQ1459919609】型孔式排種器A2.dwg大粒種子精播機(jī)的設(shè)計(jì).doc大粒種子精播機(jī)的設(shè)計(jì)任務(wù)書(shū).doc大粒種子精播機(jī)的設(shè)計(jì)開(kāi)題報(bào)告.doc大粒種子精播機(jī)的設(shè)計(jì)題目審定表.doc導(dǎo)種輪A3.dwg開(kāi)溝器A2.dwg快速精密播種機(jī)裝配圖A0.dwg排種軸A3.dwg摘要.doc播種單體機(jī)架焊合A1.dwg文件清單.txt<img src="http:/ioszen.com/ueditor_s/net/upload/2017-8/27/6363943024967615825293177_1.gif" style="float:none;" title="播種單體機(jī)架焊合A1.gif"/><img src="http:/ioszen.com/ueditor_s/net/upload/2017-8/27/6363943025064335996960687_1.gif" style="float:none;" title="導(dǎo)種輪A3.gif"/><img src="http:/ioszen.com/ueditor_s/net/upload/2017-8/27/6363943025090856031945061_1.gif" style="float:none;" title="開(kāi)溝器.gif"/><img src="http:/ioszen.com/ueditor_s/net/upload/2017-8/27/6363943025134536114643822_1.gif" style="float:none;" title="快速精密播種機(jī)裝配圖A0.gif"/><img src="http:/ioszen.com/ueditor_s/net/upload/2017-8/27/6363943025212536259069527_1.gif" style="float:none;" title="排種軸A3.gif"/><img src="http:/ioszen.com/ueditor_s/net/upload/2017-8/27/6363943025262456346281613_1.gif" style="float:none;" title="四桿機(jī)構(gòu).gif"/><img src="http:/ioszen.com/ueditor_s/net/upload/2017-8/27/6363943025312376423493699_1.gif" style="float:none;" title="限深輪.gif"/><img src="http:/ioszen.com/ueditor_s/net/upload/2017-8/27/6363943025363856513935030_1.gif" style="float:none;" title="型孔式排種器A2.gif"/><img src="http:/ioszen.com/ueditor_s/net/upload/2017-8/27/6363943025413776601147117_1.gif" style="float:none;" title="鎮(zhèn)壓輪.gif"/><img src="http:/ioszen.com/ueditor_s/net/upload/2017-8/27/6363943027179699701426554_1.jpg" style="float:none;" title="設(shè)計(jì)參數(shù).jpg"/><img src="http:/ioszen.com/ueditor_s/net/upload/2017-8/27/6363943027316979944036161_1.jpg" style="float:none;" title="設(shè)計(jì)所包含文件.jpg"/><img src="http:/ioszen.com/ueditor_s/net/upload/2017-8/27/6363943027443340172444708_1.jpg" style="float:none;" title="設(shè)計(jì)字?jǐn)?shù)統(tǒng)計(jì).jpg"/>
