Description

一种颚式破碎机 技术领域
本发明设备属于颚式破碎机技术领域，特别涉及一种颚式破碎机。
背景技术
颚式破碎机，俗称颚破，由活动颚板和固定颚板两块颚板组成破碎腔，模拟动物的两颚运动而完成物料破碎作业的破碎机。广泛运用于矿山、冶炼、建材、公路、铁路、水利和化工等行业中各种矿石与大块物料的中等粒度破碎，通常由偏心设置在飞轮上的转轴来带动活动颚板进行破碎。
由于颚式破碎机需要破碎各种不同的材料，实际使用情况较为复杂，通常在破碎的物料中会夹杂部分硬度较大的颗粒，会对破碎机产生较大的负载，当负载过大时，活动颚板无法对物料进行破碎，容易导致设备的损坏，因此，在现有的破碎机制造过程中，通常会采用脆性的肘板，且肘板通常采用两段粗中间细的结构，保证当活动颚板负载过大时，肘板断裂，保证破碎机其余部分的完整，或者在电路上使用特质的保险丝，当电机负载过大时烧毁保险丝取消对飞轮的驱动，但采用这两种方式的破碎机在实际使用中，烧毁保险丝或者肘板断裂后，质量较大的飞轮仍处于转动的状态，转轴带动活动颚板继续运动，极易损坏整体设备，且在长时间的工作后，固定颚板容易出现磨损，并减少固定颚板的厚度，以至于破碎机破碎后的物料无法达到需要的大小，因此通常需要在活动颚板的调整座与机架之间放置垫片来调节调整座与机架之间的距离，通过改变垫片的数量可以调节活动颚板与固定颚板之间的距离，来弥补固定颚板在长时间使用过后产生的损耗，但是，在调节活动颚板与固定颚板之间的距离时，为保证操作者的安全，需要断开破碎机的电源使其停机后再进行更换，且停机后需要等待质量较大的飞轮停止转动，较为耗时，加工效率较低，更换较为不便，现有技术存在可改进之处。
发明内容

作为优选，所述偏心块的一端固定设置有一个档杆，所述转轴上分别固定设置有一个限制上述转轴转动位置的第一限位杆与第二限位杆，当档杆转动至第一限位杆处时，偏心块完全位于转轴上的安装槽内，当档杆转动至第二限位杆处时，部分偏心块位于飞轮上的安装槽内。
作为优选，所述档杆的长度大于偏心块外径与第一限位杆和第二限位杆之间的最短距离。
作为优选，所述安装槽圆心处固定设置有一个转动杆，所述偏心块上开设有用于卡接该转动杆的转动槽，偏心块通过该转动槽套设在转动杆上。
作为优选，所述保护机构包括多个围绕转轴设置的滑槽，该滑槽的两端分别位于转轴与飞轮上，滑槽的轴向与转轴的轴向垂直，滑槽内活动设置有一个用于锁定转轴与飞轮的滑动销，所述滑槽位于转轴上的长度大于滑槽位于飞轮上的长度且滑动销的长度小于滑槽位于转轴上的长度并大于滑槽位于飞轮上的长度，所述转轴上固定设置有控制该滑动销移动的控制模块。
作为优选，所述滑槽与滑动销分别设置有两个且围绕转轴均匀设置，所述滑槽与滑动销一一对应。
作为优选，所述调节机构安装在调整座与机架之间，所述调节机构包括活动设置机架上用于驱动调整座向固定颚板方向移动的驱动块，所述驱动块朝向调整座的一端开设有用于驱动调整座移动并与调整座朝向驱动块端面相配合的驱动斜面，所述机架上固定设置有两个固定板，两个固定板分别位于上述驱动块移动方向的两侧，所述驱动块上通过螺纹连接活动设置有调节驱动块移动的螺杆，该螺杆贯穿上述驱动块且螺杆的长度方向与驱动块的移动方向相同，所述机架上固 定设置有两个用于支撑上述螺杆的支撑架，两个支撑架分别位于上述螺杆的两端，螺杆的两端转动设置在该支撑架上，所述机架上固定设置有控制螺杆转动的控制盒。
作为优选，所述两个固定板之间的距离与驱动块的宽度相同。
作为优选，所述每个固定板远离驱动块一侧的端面上固定设置有两个用于支撑固定板的顶板。
与现有技术先比，本发明在使用中，当活动颚板的负载过大时，通过控制模块驱动保护机构使转轴与飞轮之间的连接脱离，飞轮在转轴上空转，失去动力的转轴与活动颚板迅速停止运动，有效避免质量较大的飞轮带动转轴与活动颚板继续运动对设备造成损伤，有效保护设备，且不需要进行后续的零件更换即可继续进行破碎工作，破碎效率较高，通过控制盒控制螺杆转动，驱动块在螺杆的驱动下在两个固定板之间的间隙内移动，并通过驱动块上与调整座相配合的驱动斜面驱动调整座向活动颚板方向移动，实现弥补活动颚板与固定颚板之间的间隙，不需要停机便能够实现活动颚板与固定颚板之间的间隙大小调整，使用时较为方便。
