Description
本发明属于颚式破碎机领域，具体涉及一种硬料分解破碎机。
颚式破碎机设备中的一个主要机构是破碎腔，它由两块颚板(也称齿板或牙板)及两块边护板组成，其中由两块颚板(一块为固定颚板，一块为活动颚板)组成的破碎副是破碎腔中的核心部件。破碎比(原料尺寸与成品料尺寸之比)是破碎机的一项总体性能指标，而破碎腔是影响破碎比的结构组织部位。然而现有技术破碎腔形存在以下几点不足：从俯视上看，现有技术破碎腔形都是呈直条形的,直条形特指从破碎机俯视角度看，其破碎腔形成的物料带形状呈直条型，此时从俯视角度观察颚板表面的截面齿形即成“V”形波浪状；这种直条形腔有一个先天不足，就是没有增力效应，在破碎较硬的材料时，破碎效率不高；同时，“V”形破碎腔破碎出来的物料颗粒大小分布不均匀，如果需要破碎出颗粒大小均匀分布的骨料，现有技术技术破碎腔难以现实，因此急需设计一款可以破碎硬料的且破碎效率高的破碎机。
发明内容
本发明针对现有技术中存在的问题，设计了一款硬料分解破碎机，这种硬料分解破碎机，在原来活动颚板和固定颚板的基础上进行修改，把活动颚板和固定颚板改为上下两段，上段的齿形还是以水平方向为为阵列均匀的分布开，下段的齿形以水平方向为阵列均匀的分布开，同时从破碎机的主视图观察，活动颚板的上段与竖直方向上的下段设置了倾斜角度，通过设定一定范围的角度，可以让破碎过程更加省力，起到力的放大作用，同时可以提高了破碎效率，固定颚板的上段和下段保持与竖直方向所在平面平行；活动颚板和固定颚板的下段都改成横截面是等腰梯形的齿形后，所述的横截面的等腰梯形的斜边相互平行，在破碎过程中斜边所在的平面受力会比竖直和水平方向的力更大，从而可以破碎较硬的材料。
本发明的发明目的是通过以下技术方案实现的：一种硬料分解破碎机，包括机架、固定颚板、活动颚板、偏心轴杆、飞轮，所述的飞轮和偏心轴杆连接，所述的偏心轴杆同时还和动颚连接，动颚的上表面和活动颚板连接，固定颚板固定 在机架表层上，所述的固定颚板上段设有齿形一，下段设有齿形二，所述的活动颚板的上段设有设有齿形三，下段设有齿形四，所述的齿形在颚板表面以水平方向为阵列均匀的分布开，所述的活动颚板和固定颚板上的齿形一一对应，所述固定颚板下段所在平面和活动颚板下段所在的平面相互平行，所述的齿形二和齿形四的横截面设置成等腰梯形，从破碎机的俯视角度观察，活动颚板和固定颚板凹凸交错的齿形形成破碎腔。
作为优选，从破碎机的水平横向截面观察，所述的固定颚板上段的齿形一和活动颚板的上段的齿形三的截面呈现均分分布的梯形状，所述梯形状的波峰与波谷一一对应。
作为优选，所述的齿形一与齿形三水平横向截面还可以设置成波浪形或者“V”形。
通过设置齿形一与齿形三的形状，可以让破碎机在破碎不用的材料有更快的效率。
作为优选，所述活动颚板分为上下两段，活动颚板的下段是与竖直方形平行，从破碎机的主视图观察活动颚板的上段，所述活动颚板的上段与竖直方向平行的下段存在倾斜角度，倾斜角度设置在17-26度。
通过设定一定范围内的倾斜角度，可以让上段破碎过程更加省力，提高破碎效率。
作为优选，所述固定颚板和活动颚板的下段设有横截面是等腰梯形的齿形，所述齿形二的和齿形四的的很截面所形成的等腰梯形大小形状设置相同。
作为优选，所述齿形二分布在固定颚板表面，所述齿形四分布在活动颚板表面，齿形二与齿形四以水平方向阵列，齿形二与齿形二之间会形成凹槽一13，齿形四与齿形四之间会形成凹槽二14，所述凹槽一13和凹槽二14的大小和形状相同。
作为优选，所述凹槽的外形轮廓可以与颚板表面的齿形相互匹配，从破碎机的俯视角度观察，凹槽的横截面可以通过齿形的横截面等距形成。
通过限定凹槽和齿形的大小，可以让活动颚板和固定颚板的齿形在破碎时形成间隙，从而可以筛选材料。
作为优选，所述齿形二的表面设有切面一，所述齿形四的表面设有切面二， 所述的切面一和切面二相互平行，颚板与齿形连接的平面与所述的切面存在角度，所述的角度大于90度。
与现有技术相比，本发明具有以下有益效果：所述活动颚板分为上下两段，活动颚板的下段是与竖直方形平行，从破碎机的主视图观察活动颚板的上段，所述活动颚板的上段与竖直方向的平行下段存在倾斜角度，倾斜角度设置在17-26度，通过设定这个范围的倾斜角度，可以让第一阶段的破碎过程更加省力，起到力的放大作用，提高了破碎效率，这样就可以破碎较硬的物料；活动颚板和固定颚板的下段都改成横截面是等腰梯形的齿形后，所述的横截面的等腰梯形的斜边相互平行，在破碎过程中斜边所在的平面受力会比竖直和水平方向的力更大，从而可以破碎较硬的材料。

下面结合附图所表示的实施例对本发明作进一步描述：
实施例1
如图1、图2、图3、图4、图5所示，一种硬料分解破碎机，包括机架1、固定颚板2、活动颚板3、偏心轴杆4、飞轮5，所述的飞轮5和偏心轴杆4连接，所述的偏心轴杆4同时还和动颚6连接，动颚6的上表面和活动颚板3连接，固定颚板2固定在机架1表层上，所述的固定颚板2上段设有齿形一7，下段设有齿形二8，所述的活动颚板3的上段设有设有齿形三9，下段设有齿形四10，所述的齿形在颚板表面以水平方向为阵列均匀的分布开，所述的活动颚板3和固定 颚板2上的齿形一一对应，所述固定颚板2下段所在平面和活动颚板3下段所在的平面相互平行，所述的齿形二8和齿形四10的横截面设置成等腰梯形，从破碎机的俯视角度观察，活动颚板3和固定颚板2凹凸交错的齿形形成破碎腔11；所述活动颚板3在运行时，完全和动颚6固定，所述动颚6与肘板15连接，所述肘板15的另一端与调整垫块18连接，调整垫块18下方设有通孔，拉杆16穿过通孔后在通过螺钉固定在破碎机上，所述的拉杆16中间穿有弹簧17，所述的弹簧17可以使调整垫块18进行复位。当破碎机的电机进行工作时，电机通过皮带带动飞轮5转动，飞轮5转动后会带动偏心轴杆4转动，此时偏心轴杆4会带动动颚6运动，动颚6同时通过肘板15、调整垫块18以及连杆上的弹簧17在水平方向就会产生往复运动，这样加上偏心轴杆4带动动颚6运动，动颚6就会形成偏心运动，和动颚6连接的活动颚板3就可以和固定颚板2进行破碎工作。
从破碎机的水平横向截面观察，所述的固定颚板2上段的齿形一7和活动颚板3的上段的齿形三9的截面呈现均分分布的梯形状，所述梯形状的波峰与波谷一一对应；所述的齿形一7与齿形三9水平横向截面还可以设置成波浪形或者“V”形；所述活动颚板3分为上下两段，活动颚板3的下段是与竖直方向平行，从破碎机的主视图观察活动颚板3的上段，所述活动颚板3的上段与竖直方向平行的下段存在倾斜角度12，倾斜角度12设置在17-26度。
在这个角度范围内进行破碎工作，破碎的效率会提高，同时斜面会使破碎更加省力，在水平方向施加同样大小的力作用下，垂直斜面向上会得到更大的力，起到力放大的作用。
所述固定颚板2和活动颚板3的下段设有横截面是等腰梯形的齿形，所述齿形二8的和齿形四10的的横截面所形成的等腰梯形大小形状设置相同；所述齿形二8的表面设有切面一19，所述齿形四10的表面设有切面二20，所述的切面一19和切面二20相互平行，颚板与齿形连接的平面与所述的切面存在角度，所述的角度大于90度；通过设定切面和颚板表面的角度，可以让齿形的切面在受到材料的作用力时，可以把作用力放大，这样切面反作用给材料的力同样放大，这样就可以破碎更加坚硬的材料。
所述齿形二8分布在固定颚板2表面，所述齿形四10分布在活动颚板3表 面，齿形二8与齿形四10以水平方向阵列，齿形二8与齿形二8之间会形成凹槽一13，齿形四10与齿形四10之间会形成凹槽二14，所述凹槽一13和凹槽二14的大小和形状相同；所述凹槽的外形轮廓可以与颚板表面的齿形相互匹配，从破碎机的俯视角度观察，凹槽的横截面可以通过齿形的横截面等距形成。凹槽与齿形的外形轮廓可以相互配，同时凹槽可以通过齿形等距形成，这样齿形一7与齿形二8之间就会形成间隙，从而起到筛选物料的作用。
具体的，当需要破碎操作时，打开破碎机的驱动电机，这时破碎机的活动颚板3就会产生往复运动，这样活动颚板3上上段的齿形一7就会和固定颚板2上段的齿形三9进行第一阶段的破碎，把较硬的物料破碎出来，第二阶段通过活动颚板3上的齿形四10和固定颚板2上的齿形二8限定尺寸破碎，破碎出大小均匀的形状，从而达到了破碎较硬物料的目的。
文中所描述的具体实施例仅仅是对本发明精神作举例说明。本发明所属技术领域的技术人员可以对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，但并不会偏离本发明的精神或者超越所附权利要求书所定义的范围。
