卸料器结构设计 摘 要 随着工业产业的快速发展，一些粉尘颗粒和煤炭的输送环节在企业的生产中占据重要地位，卸料器是运输环节不可缺少的设备，卸料器的应用大大提升了企业的生产力。 本设计对卸料器的总体结构和主要组成部分进行了分析，卸料器由犁头、电液推杆、机架、电机、小车、活动托辊、导料槽等部分组成，每个部件在卸料器的工作过程中都发挥着重要的作用。首先，对卸料器的工作过程及工作原理进行了介绍，接着，分析了卸料器的组成部分及主要部件分析，最后对卸料器的液压结构运用、电动推杆选择、电机选择进行了详细的介绍，最后一章还对卸料器犁头的受力情况进行了有限元分析，把卸料器在动态和静态下的物理状态表现出来。 目前，卸料器经过各个技术领域的改进，摆脱了原先经常发生的机械故障，进一步完善了可调的犁头角度，保证了传送机的稳定性，大大提高了工作的效率。 关键词 卸料器；矿山机械；结构力学分析  Unloader Structuer Design Abstract With the rapid industrial development, a number of coal dust particles and transport sectors occupy an important position in the production, transport links unloader is indispensable equipment, unloader applications greatly enhance the companys productivity. The design of the overall structure of the discharger and the main part was analyzed by the plow unloader, electro-hydraulic putt, chassis, motor, car, activities rollers, chutes and other components, each component during operation of the discharger have played an important role. First, discharge the working process and working principle were introduced, followed by analysis of the components of the discharge device and main components analysis, and finally the use of hydraulic structures discharger, the electric putter selection, the motor selection in detail, the last chapter also unloader plow the force carried out a finite element analysis, the dynamic and static discharge in the physical state under manifested. Currently, the unloader improved in various technical fields, out of the original mechanical failure often happens, to further improve the plow angle adjustable, to ensure the stability of the conveyor, greatly improving the work efficiency.
