Description

一种圆锥破碎机结构
技术领域
本发明涉及碎石装置领域，特别是涉及一种圆锥破碎机结构。
背景技术
圆锥破碎机在外壳内设置绕轴偏心转动的下破碎壁，并在下破碎壁上部设置固定罩扣在下破碎壁上的上破碎壁，通过偏心轴带动下破碎壁偏心转动与上破碎壁内侧挤压石块来对石块进行破碎。
以往是圆锥破碎机的上破碎壁底部内径和下破碎壁的底部外径大体相等，此类圆锥破碎机结构方便破碎机的生产、加工和组装，但在破碎机的实际工作过程中，上下破碎壁的底部间空隙较大，会造成较大的加工空间的浪费。现有破碎机的上破碎壁与下破碎壁的下端最大直径是基本相等的，如规格2.2m的破碎机其上破碎壁与下破碎壁的下端最大直径就是2.2m，正因为现在的破碎机的上下破碎壁的直径一样，在破碎机使用过程中，下破碎壁最大直径部分约1～6厘米位置不能与上破碎壁同时磨损，而且下破碎壁最大直径1～6厘米位置那部分与下破碎壁其他破碎壁位置也不一致，通常是1～6厘米的位置磨损的比较慢，磨损得比较慢的原因是因为上破碎壁与下破碎壁的最大直径一致造成的，正因为下破碎壁最大直径部分1～6厘米磨损的比较慢，当上下破碎壁在使用过程中磨损越大，下破碎壁最大直径1～6厘米部分突出就越高，当这突出部分越高造成破碎后的石料排除越慢，当上下破碎壁磨损到50%之后，产量明显下降，最终上下破碎壁在使用到70%的时候就被逼淘汰。

进一步作为本发明技术方案的改进，过载保护联轴器为机械连接过载联轴器、电磁式过载联轴器和液压式过载联轴器中的一种。
进一步作为本发明技术方案的改进，过载保护联轴器为机械连接过载联轴器，所述过载保护联轴器包括套设在动力输入轴和电机输出轴外的连接环，环绕所述连接环的内壁与动力输入轴和电机输出轴的外壁间设有若干橡胶棒。

优选设置为上破碎壁2底部的最大内径较下破碎壁3底部的最大外径大15cm，此距离的设置考虑到碎石下落的角度，以及碎石位于碎石工作区域下部的碎石状态，可使得上破碎壁2的底部对下破碎壁3底部进行全包裹，并能有效节省材料。
作为本发明优选的实施方式，上破碎壁2与下破碎壁3间的距离从上至下递减，上破碎壁2的壁厚从上至下均递增，下破碎壁3下部的壁厚由中部向上下两侧递减。

作为本发明优选的实施方式，下破碎壁3的上部设有环绕下破碎壁3顶端的挡环34。
挡环34的设置是为了减少进入破碎机内的大石块对破碎壁本体表面的损伤，挡环34可对进入破碎机内的大石块进行适当阻挡。
收边阶梯33采用竖直向下的坡度设置，在经过破碎壁挤压破碎后的小石块的下落过程中，小石块不会与下破碎壁3的底部产生碰撞，可有效避免破碎机工作效率的降低，也可防止破碎壁本体被快速破坏。
作为本发明优选的实施方式，外壳1的内侧位于上破碎壁2和下破碎壁3底部的部分成倒锥形设置，外壳1的内侧位于倒锥形壳体部分的底部呈柱形。
作为本发明优选的实施方式，上破碎壁2通过破碎壁安装座22固定安装在外壳1的顶部,破碎壁安装座22螺纹连接于外壳1的顶部，破碎壁安装座22顶部的内径小于底部的内径，破碎壁安装座22的顶部设有向外侧倾斜的坡口23。
作为本发明优选的实施方式，外壳1内腔内呈倒锥形设置部分位于破碎壁安装座22的底部以下。
作为本发明优选的实施方式，外壳1包括可分离的外壳上部分11和外壳衬板12，外壳1上的倒锥形部分和柱状部分组成外壳衬板12。
在外壳1中部设置倒锥形的内腔，使得外壳1下部直径扩大，可有效避免碎石下落过程中与外壳1的内腔发生碰撞，破碎壁安装座22用于安装可更换的上破碎壁2，可方便在上破碎壁2损坏后进行拆卸，以维修或者更换，破碎壁安装座22上设置的坡口23可方便更大尺寸石块的置入，外壳1的整体结构可减少石块置入及下落过程中对外壳1内腔的损坏，从而提高外壳1的使用寿命。
石块经过破碎机挤压破碎后，从上破碎壁2和下破碎壁3的底部下落，位于破碎壁安装座22底部以下的倒锥形部分，内腔直径尺寸明显增大，可有效避免与碎石的碰撞。
外壳1设置成可分离的形式，虽然外壳1内腔形状的设置可减少内腔与石块间的碰撞而影响破碎机外壳1的使用寿命，但外壳1内腔的损坏不可避免，在外壳1损坏后，分体式的外壳1结构设置，可方便快速拆卸外壳衬板12，且可通过仅拆卸维修或者更换外壳衬板12，即可完成对外壳1整体的更新，可节省破碎机维修的劳动强度。
作为本发明优选的实施方式，外壳1下部还设有水平伸出的动力输入轴5，动力输入轴5通过与固定安装在偏心轴4外的轴套通过锥齿轮啮合带动，还设有与动力输入轴5相连的电机和电机输出轴6，动力输入轴5和电机输出轴6间通过过载保护联轴器连接，过载保护联轴器在动力输入轴5和电机输出轴6的连接处的扭矩超过设定扭矩时断开连接。
作为本发明优选的实施方式，过载保护联轴器为机械连接过载联轴器、电磁式过载联轴器和液压式过载联轴器中的一种。
作为本发明优选的实施方式，过载保护联轴器为机械连接过载联轴器，所述过载保护联轴器包括套设在动力输入轴5和电机输出轴6外的连接环61，环绕所述连接环61的内壁与动力输入轴5和电机输出轴6的外壁间设有若干橡胶棒62。
作为本发明优选的实施方式，动力输入轴5和电机输出轴6的外壁设有孔槽，所述连接环的内壁设有内槽，所述孔槽和内槽配合形成固定橡胶棒62的安装孔。
通过过载保护联轴器连接动力输入轴5和电机输出轴6，可通过过载保护联轴器来实现对破碎机主要零部件的保护，在碎石过程中当遇到难以压碎的杂物出现卡顿对破碎机造成冲击时，破碎机可以通过扭动或者剪断联轴器来消除突发过载冲击力对破碎机的损坏，且过载保护联轴器结构简单、成本低廉，同时可方便破碎机抗冲击结构的安装和维修。
联轴器在机器遇到较大冲击并超出设计最高载荷时会自动断开传动轴和电机之间的连接，保护机器内各重要零部件不容易受到损坏。
当然，本发明创造并不局限于上述实施方式，熟悉本领域的技术人员在不违背本发明精神的前提下还可作出等同变形或替换，这些等同的变型或替换均包含在本申请权利要求所限定的范围内。
