摘　　要：针对目前世界各国对农产品的需求越来越大,中国农业播种机技术还不成熟且难以普及等问题,对播种机的排种器、排肥器、开沟器、旋耕器等部件进行了研究,设计了一种可调式免耕播种机。其中开沟器可以同时破开两条具有高度差的种沟和肥沟,排种器可以通过调节孔挡板扦插进排种器外壳内的深度来实现播种速度的调节。研究结果表明,该设计能够避免种子在吸收肥料的过程中发生烧苗、烧根等现象,并且能够根据不同的播种要求调节播种速度。In view of the increasing demand for agricultural products in the world,the technology of our country's agricultural seeder is not mature and difficult to be popularized,this paper studies and designs the seed metering device,fertilizer discharging device,furrow opener and rotary tiller of the seeder,and puts forward a kind of intelligent adjustable no-tillage seeder.In this design,two seed trenches and fertilizer trenches with different height can be broken at the same time by using the ditcher,and the sowing speed can be adjusted by adjusting the distance of the hole baffle cutting into the shell of the seed metering device.The results show that the design can avoid the seed burning in the process of absorbing fertilizer or the heat from fermenting fertilizer,and it can adjust the sowing speed according to different sowing requirements,and have certain practicability and innovation.
