Description

一种可筛选破碎机 技术领域
本发明属于颚式破碎机领域，具体涉及一种可筛选破碎机。
背景技术
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；从侧视截面上看，现有技术破碎腔型基本是呈“V”形的。这“V”形是制约高破碎性能的主要因素之一，它每一冲程完结时排放的物料容积是底部的三角区，在这三角区里，上部尺寸大、下部尺寸小，显然，这种腔形排放出来的料，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。同时，在破碎带有钢筋的物料时，现有技术的破碎腔难以把钢筋上的材料破碎完全，会有部分材料连在钢筋上，导致破碎效果不好，因此急需设计一款新型高效的可以筛选材料的破碎机。
发明内容
本发明针对现有技术中存在的问题，设计了一款可筛选的破碎机，这种可筛选的破碎机，在原来活动颚板和固定颚板的基础上进行修改，现有技术中固定颚板和活动颚板上凹凸配对的齿形之间在齿形完全配合到位时，即固定颚板和活动颚板运动到最近位置时，齿与齿之间的基本是没有缝隙的，现在把固定颚板和活动颚板齿形之间的间隙加大，在固定面积的颚板表面，减少齿形数量，这样固定颚板和活动颚板上凹凸配合的齿形就可以形成间隙，通过控制间隙的大小，从而去限定破碎物料的大小；同时增加了活动颚板和固定颚板竖直长度，这样长度加长后，可以延长物料的破碎时间，可筛选出带有钢筋等硬物的石材。
本发明的发明目的是通过以下技术方案实现的：一种可筛选破碎机，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，所述的固定颚板的上表面一设有齿形一，所述的活动颚板的上表面二设有齿形二，所述的齿形一和齿形二在颚板表面以水平方向为阵列均匀的分布开，齿形凹凸分布，活动颚板和固定颚板上凹凸分布的齿形一一对应，从破碎机的俯视角度观察，活动颚板和固定颚板凹凸交错形成破碎腔。
作为优选，所述的固定颚板上的每个齿形一之间的间距相同，所述活动颚板上的每个齿形二之间的间距相同，固定颚板上齿形的间距和活动颚板的齿形间距相同。
通过设定每个齿形之间的间距相同，所述齿形与齿形形成的凹槽从俯视角度观察齿形一和齿形二所所形成的间隙会保持一致，这样就可以先限定物料的尺寸。
作为优选，所述的固定颚板任意凸出的两个齿形一会形成一个凹槽，所述的凹槽会与活动颚板上凸出的齿形二进行配合破碎；破碎机水平放置时，两个齿形一之间的凹槽的左右表面会与齿形二的左右表面形成两个间隙，所述的间隙的厚度相同。
通过活动颚板和固定颚板表面设定的向外凸出的齿形，齿形会相互交叉配合破碎，由于破碎的间隙厚度相同，这样就可以再进一步筛选出破碎材料的尺寸了。
作为优选，所述固定颚板上每个齿形一的厚度相同，所述活动颚板上每个齿形二的厚度相同，齿形一的后厚度和齿形二的厚度也相同；固定颚板上的每个齿形一垂直于上表面一方向观察时向外凸出高度相同。
作为优选，齿形与齿形之间所形成的凹槽厚度大于每个单一齿形的厚度。
当设定所述凹槽的厚度大于每个单一齿形的厚度时，活动颚板上和固定颚板上凹凸配合的齿形就会形成间隙，间隙大小可以通过齿形厚度以及齿形之间的间距控制。
作为优选，从破碎机纵向截面观察，齿形一平行于上表面一的位置设有齿口一，齿形二平行于上表面一的位置设有齿口二，齿口一和齿口二在破碎机运行过程中，不会与固定颚板的上表面一，活动颚板的上表面二发生接触。
通过限定固定颚板上向外凸出的齿形一的凸出高度，可以保证固定颚板上的 齿口一和活动颚板上的齿口二不会与颚板表面接触，可以让齿形有更长的使用时间，不至于短时间内更换。
与现有技术相比，本发明具有以下有益效果：在原来活动颚板和固定颚板的基础上进行修改，现有技术中固定颚板和活动颚板上凹凸配对的齿形之间在齿形完全配合到位时，即固定颚板和活动颚板运动到最近位置时，齿与齿之间的基本是没有缝隙的，现在把固定颚板和活动颚板齿形之间的间隙加大，在固定面积的颚板表面，减少齿形数量，这样固定颚板和活动颚板上凹凸配合的齿形就可以形成间隙，可以让破碎材料在方形齿形的限定下，破碎出大小均匀的材料；可以通过调节齿形上下间距，按实际需求，破碎出所需尺寸的材料；同时同时增加了活动颚板和固定颚板竖直长度，这样长度加长后，可以延长物料的破碎时间，可筛选出带有钢筋等硬物的石材。

具体实施方式
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6，图7所示，一种可筛选破碎机，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同时还和动颚连接，动颚14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的上表面一6设有齿形一7，所述的活动颚板3的上表面二8设有齿形二9，所述的齿形一7和齿形二9在颚板表面以水平方向为阵列均匀的分布开，齿形凹凸分布，活动颚板3和固定颚板2上凹凸分布的齿形一一对应，从破碎机的俯视角度观察，活动颚板3和固定颚板2的齿形凹凸交错形成破碎腔10；所述活动颚板3在运行时，完全和动颚14固定，所述动颚14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会带动颚14运动，动颚14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14运动，动颚14就会形成偏心运动，和动颚14连接的活动颚板3就可以和固定颚板2进行破碎工作。
所述的固定颚板2上的每个齿形一7之间的间距相同，所述活动颚板3上的每个齿形二9之间的间距相同，固定颚板2上齿形的间距和活动颚板3的齿形间距相同；所述的固定颚板2任意凸出的两个齿形一7会形成一个凹槽，所述的凹槽会与活动颚板3上凸出的齿形二9进行配合破碎；破碎机水平放置时，两个齿形一7之间的凹槽的左右表面会与外凸齿形二9的左右表面形成两个间隙11，所述的间隙11的厚度相同；所述固定颚板2上每个齿形一7的厚度相同，所述活动颚板3上每个齿形的厚度相同，齿形一7的厚度和齿形二9的厚度也相同；固定颚板2上的每个齿形一7垂直于上表面一6向外凸出的高度相同；从破碎机纵向截面观察，齿形一7平行于上表面一6的位置设有齿口一12，齿形二9平行于上表面一6的位置设有齿口二13，齿口一12和齿口二13在破碎机运行过程中，不会与固定颚板2的上表面一6，活动颚板3的上表面二8发生接触。通过限定齿形一7和齿形二9垂直于颚板表面外凸的高度和齿形的厚度，可以让破碎的材料有更均匀的尺寸，同时实际要求破碎出所需要的尺寸。
实施例2
如图1、图2、图3、图4、图5所示，当破碎机需要破碎钢筋等材料时，其他所有的结构同实施例1相同，具体改进就是增加了活动颚板3和固定颚板2 竖直长度，这样长度加长后，可以延长物料的破碎时间，从而筛选出带有钢筋等硬物的石材，可以保证石材不会黏连在钢筋上。从图5可以看出，活动颚板3上表面二8上会受到三个方向上的力，水平方向上的力F1由于动颚14和调整垫块18在水平往复运动产生，竖直方向上的力由于偏心轴杆4逆时针方向转动，会对动颚14在竖直方向产生分力F2，F1和F2会产生垂直于上表面二8的合力F3，因此当动颚14产生力的作用时，动颚14表面会把水平方向上的力进行放大，从而提高了破碎效率。
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上的齿形二9就会和固定颚板2上的齿形一7进行破碎，进入破碎腔10后的材料，会在间隙11的限定下，破碎出大小均匀的形状，从而达到了筛选破碎的目的。
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。
