Description

雷蒙粉碎机的改进结构 技术领域
本发明涉及一种粉碎矿石的雷蒙粉碎机。
背景技术
现有的雷蒙粉碎机，在粉碎矿石粉沫的过程中，主要是以位于粉碎机底盘之下的电动机，带动直接与其相连接的中心花架转动，并将悬吊在中心花架周边的滚轮转动，在离心力的作用之下，滚轮则在旋转中所产生的离心力推动下悬飞中向碾壁施以挤压力，从而将飞夹在滚轮与碾壁间的矿石碾成粉末。
但由于杆状摇臂是上端联接在中心花架的周边，下端却是空悬在碾底上面，碾壁周圈起来的空间，貌似钟摆式的悬吊在空中，当雷蒙机内腔添加进矿石之后，滚轮遇到成堆的矿石时，成堆的矿石就会对滚轮形一个相对的阻挡力，滚轮就会产生一反作用，并将这一反作用力通过摇臂传导向与其相联接的中心花架周边的联接处。当这一反作用力通过摇臂传导到该连接点处时，则被悬吊状的摇臂转变成杠杆力，作用在中心花架的周边，周而复始，这一被放大了的反作用力，就致使中心花架悬吊摇臂的联接点处的机体发扭曲形变。从而引起雷蒙粉碎机在粉碎矿石的过程中，不仅嗓音倍增，而且伴有强烈的震动，形成机器的损坏。
 技术问题
本发明的目的就是提供一种，能够避免中心花架出现扭曲形变，造成雷蒙粉碎机损坏的雷蒙粉碎机新结构。
技术解决方案
参考图1我们可以看到：现在的雷蒙粉碎机的电动机1是安装在底盘5之下，并由底盘5的中心穿透，与位于底盘5之上的中心花架2的中心固定联接，在中心花架2的周边则悬吊安装着多个摇臂6，摇臂6的上端是呈活动状态安装在中心花架2的周边。摇臂6的下端则是悬吊状活动联接着滚轮3，滚轮3则是和中心花架2呈一体，在底盘5的上表面，被圆圈的碾壁圈围在中心。
当位于底盘5之下的电动机1启动之后，同步带动中心花架2快速旋转，中心花架2旋转中则带动安装在，中心花架2周边悬吊的摇臂6和其下端悬吊状安装联接的滚轮3，跟随中心花架2的周边同步旋转，在快速的旋转之中的离心力推动之下，滚轮3则在摇臂6的悬吊中推向碾壁4的内表面。从而对夹在滚轮3和碾壁4之间的矿石施以挤碾粉碎。在这一挤碾粉碎的过程之中，一旦矿石成堆积状阻挡在滚轮3的前面，滚轮3必然受到强大的反作用力，并通过摇臂6将这一反作用力传导向中心花架2的周边联接处，最终导致中心花架2的周边联接处扭曲变形，致使粉碎机最终被破坏。
 有益效果
为了根除这一结构上的缺点，（参考图2结构示意图）本发明的设计结构中，将摇臂6（图1）摘掉，而将滚轮3直接安装在中心花架2的周边机体之中，位于中心花架2周边的多个滚轮是活动状态安装在中心花架2的周边，他们各自都可以再各自的活动结构之中，做径向的往复滑动，当遇到堆状的矿石之际，滚轮3就会在结构中沿径向中心花架2的中心滑动，而不会有摇臂6的杠杆力破坏，扭曲中心花架2.因此当在碾壁和滚轮3之间碾压粉碎矿石之际，雷蒙粉碎机的安全性得到了更好的保障。
附图说明
图1是改进前的雷蒙粉碎机结构示意图。
图2是改进后的雷蒙粉碎机结构示意图。
 本发明的实施方式
下面结合附图2和实施例对本发明作进一步详细描述：
如图2所示：电动机1设置在雷蒙粉碎机的底盘之下，电动机1的主轴则经由底盘5的中心与底盘5之上的中心花架2的中心固定联接在一起，在中心花架2的周边则安装了多个可以沿个自径向方向自由滑动的滚轮3.在这个组合体的外围，底盘5之上，则设置了圆形的碾壁4.
当操作人员启动了电动机1之后，电动机1则就带动固定安装在其上端的中心花架2绕电机1中心轴快速转动，快速转动的中心花架2在转动中将随着转速的速度，同步产生很大的离心力。在这一离心力的推动下，安装在中心花架2周边的滚轮3，则在这离心力的推动下压向外围的碾壁4，滚轮3则在中心花架2的带动下，沿碾壁4内表面滚动，并在滚动的同步碾压，粉碎位于滚轮3和碾壁4之间的矿石，使矿石在反复的碾压过程最终成为粉末状态。
