摘　　要：为解决堆肥机械化施肥问题,研究设计地轮驱动输肥、片式双螺旋破碎抛撒施肥装置。利用ANSYS Workbench对螺旋刀轴进行有限元模态分析,确定固有频率对螺旋刀轴影响;运用Matlab仿真地轮驱动输肥模型,分析运动阻力转矩与垂直载荷转矩关系以及地轮驱动输肥原理。应用Catia软件仿真该装置结构参数等,获得作为样机设计依据结构参数及相应运转工艺参数,制作工程样机并验证,试验过程中输肥与抛撒配合良好,达到堆肥撒施要求。研究可为适合堆肥施用特点的抛撒施肥机具研发提供借鉴。To solve the problem of compost fertilizer mechanization,a ground wheel drive to delivery of fertilizer and vane-type double helix broken scatter fertilizer machine was designed.During the process of designing,ANSYS Workbench was used to carry on finite element modal analysis on the spiral knife shaft and confirmed the effect of inherent frequency on the spiral knife shaft.Matlab was used to make simulation experiment on the ground wheel driven spread fertilization,analyzing the relationship between the motion resistance torque and vertical load torque,also the ground wheel driven spread fertilization theory.At the same time,using Catia simulated and optimized this equipment structure parameter to gain prototype design reference's structural parameter and corresponding operation process parameters,and on this basis made the engineering prototype and done the verification test.During the test,fertilizer delivery and drip combined very well,it was satisfy the requirement of organic fertilization.It can provide a reference for the research and development of compost fertilizer application tools.
