整地播種機的設(shè)計
摘要：整地式播種技術(shù)是一種集整地破土，施肥，播種，鎮(zhèn)壓為一體的農(nóng)業(yè)耕作機械設(shè)備，是我國實現(xiàn)農(nóng)業(yè)耕作現(xiàn)代化，大面積栽種，集成化的重要手段，2003年，我國在大范圍內(nèi)使用整地式播種機進行種植的面積，產(chǎn)量居于世界領(lǐng)先行列，但是，目前我國自產(chǎn)的整地播種機，還存在一些缺陷，主要是旋耕刀容易磨損或者變形，播種穩(wěn)定性差，效率比較低。導(dǎo)致這一系列情況的主要因素是，由于使用的材料性能，結(jié)構(gòu)設(shè)計，整地旋耕刀滾與播種，鎮(zhèn)壓之間的速度與方式匹配不合理等因素造成。所以目前的主要任務(wù)是，如何提高整地式播種技術(shù)的運用，改善其結(jié)構(gòu)方式，提高其工作效率等，幾個方面進行改進，才能取得更好的耕種效果。提高機械化用于生產(chǎn)中，是相對來說比較有效的方式，所以這就要求，各種性能先進，種植效率較高，通用性廣泛以及適應(yīng)性強，基本結(jié)構(gòu)簡單，易于加工制造與維護的整地式播種機，能夠不斷被設(shè)計出來，并且能夠得到大力的推廣，與應(yīng)用當(dāng)中。相對類似產(chǎn)品來說整地式播種機，其結(jié)構(gòu)比較簡單，工作相對可靠，效率比較高，而且不容易傷到種子。目前在國內(nèi)外，正快速發(fā)展并且逐漸在農(nóng)業(yè)中得到廣泛的使用。本設(shè)計的研究目標(biāo)是：尋求一種最佳的整地式整地模式，能夠在生產(chǎn)效率，可靠性，便于操作性，降低制造成本等方面綜合考慮，改進我國傳統(tǒng)整地機械的缺陷，得到一種具備市場競爭力以及技術(shù)創(chuàng)新性的整地式播種機。只有綜合性能優(yōu)越，各機構(gòu)之間匹配合理才能使得整地播種機取得新的突破。

Design of tillage seeder
Abstract: Ploughing planting technology is a collection of ground breaking soil preparation, fertilization, planting, suppression of farming machinery and equipment, is the realization of agriculture modernization in our country, large area planted, integrated important means, in 2003, our country on a larger scale using soil preparation type seeder for planting area, yield one of the world's leading ranks, but at present our country produced the soil preparation of seeder, there are still some defects, mainly is the rotary tillage blade wear and tear or deformation, poor stability, sowing efficiency is low. Lead to this a series of case is the main factor, due to the use of material properties, structure design, site preparation rotary knife roll and sowing, suppress the speed and mode matching between the unreasonable factors such as. So the main task of the current is, how to improve the use of the site preparation type planting technology, improve its structure, improve the work efficiency and so on, several aspects to improve, to achieve better effect of farming. Improve mechanization for production, is a relatively effective way, so it requires, advanced performance, high efficiency, wide commonality and strong adaptability, basic simple structure, easy manufacture and maintenance of soil preparation type seeder, constantly were designed, and the ability to get a promotion, and application. Soil preparation type seeder compared with similar products, its structure is simple, relatively reliable, work efficiency is higher, and it is not easy to hurt the seeds. At present, both at home and abroad is rapid development and gradually has been widely used in agriculture. This design research goal is: to seek a best mode of no-till soil preparation type, can in the production efficiency, reliability, easy operation, lower manufacturing cost, etc, comprehensive consideration, to improve the defects of traditional no-till machinery in our country, have a soil preparation have market competitiveness and technological innovation type seeder. Only the comprehensive performance is superior, the reasonable matching between the agencies to make a new breakthrough in soil preparation machine
