1、毕业设计说明书深松小麦施肥播种机设计II摘要此论文主要讲述的是深松小麦施肥播种机的设计，它是一种近年来新兴起的全能型小麦播种机具，主要特点是施肥效率高、播种均匀、改善土壤结构并且能使小麦获得良好的生长发育条件。深层疏松土壤是提高农作物产量的重要途径，对促进农业得到更好地发展，确保中国农作物高产具有极其重要的意义。在拖拉机向前运行过程中，凿形深松铲深入地面以下30厘米左右，在拖拉机牵引下完成了深层疏松土壤的过程；与此同时发动机的动力通过万向节和变速箱传递给凿形深松铲后面的旋耕机构。旋耕机构采用全幅旋的方式对小麦的苗带行的泥土进行全面的旋耕，旋耕深度在15厘米

2、左右。紧接着旋耕机构后面的箭形开沟器开出小麦的苗带，为小麦的播种做出准备。排种器和排肥器的动力来自于机架后方的镇压轮，排种器排出的小麦种子通过导种管进入宽苗带排种口，宽苗带排种口的宽度为12厘米，与苗带宽度一致，实现宽苗带播种；排肥器通过排肥管与深松铲相连，在深松铲完成对土壤的深松的同时实现深层施肥。本机器并未设置覆土板，原因是旋耕刀向后抛起的泥土遇到挡土罩壳后既起到碎土的功能，破碎后的泥土直接落到未覆盖的苗带上，经过覆盖泥土的小麦种子经由镇压轮的镇压后便完成了全部的播种的过程。关键词：凿形深松铲，深层施肥，宽苗带播种，镇压IIAbstractAbstra
