摘要
隨著近來溫室大棚的發(fā)展以及環(huán)保發(fā)展意識的日益增強，小型機的需求就顯得更為重要，尤其以電力為動力裝置的機械。然而目前廣泛應用的播種機是以內(nèi)燃機及人力為動力裝置。本設計電動小型播種機與傳統(tǒng)的播種機相比.新穎之處在于播種機完全采用電力為動力裝置，從而改善了人們在田間作業(yè)時的工作環(huán)境，況且更符合環(huán)保發(fā)展的觀點。
本設計主要用于農(nóng)戶田間播種和設施種植播種.增加部分裝置也可用于施肥、耙磨、除草等田間作業(yè)。詳細介紹了播種機的結構組成以及各部件的形式、要求以及功用。詳細介紹了電動小型播種機動力裝置及各部件要求，包括播種機的動力選擇、機械傳動的選擇及尺寸、排種輪設計、排肥輪的設計、開溝器的設計、軸的設計、鏈輪的設計、其他的各部件設計以及播種機的工作要求、播種前的準備及播種機的使用等。在設計中考慮播種深度連續(xù)可調(diào)、播種行距連續(xù)可調(diào)、播種穴距可調(diào)、種子破碎率和播種均勻度符合國家標準。設計中在考慮實用的同時，兼顧經(jīng)濟節(jié)約，從而達到結構合理、生產(chǎn)成本低、能耗小、效率高，而且操作方便的目的。

Abstract
With the development of the greenhouse and the consiousness of protecting our ervironment ,boosting up ,the apply of the powy machine becomes more important ,especially the machine with electric power .but at the present time the seeding-machine which is adopted abroadly is drived ba gad engine or man power .this kind of minitype seeding-machine knows from the conventional seeding-machine .Its novel aspect is its drive set which are drived by electric power completly ,so they will improve the work condition ,and accord with euthenics .
This design is applied mostly with the farms of the farmers ,they can also used to fertilize、abrade、get rid of grass and so on ,when we incress some equipment .My design introduce the structure of the seeding-machine and the types of many parts 、some request an fuction .My design introduce the drive equipment of the machine and the types of many parts 、request and fuction .My design also introduce the drive equipment of the machine and the request of the parts which consist of the selecting of the power 、the size 、the design of the axial 、chain wheel 、some other parts and so on .We must consider suiting well of the depth 、the row spacing 、the distance of scoop and the rate of seeds breaking up when seeding .In my design ,while thinking over applied ,I give attention to saving econmy ,consequently achieve structure in reason 、the cost of produce lowness 、the cost of power lowness 、the effidiency highness and convenient when operating .
