Description
本发明设备属于颚式破碎机技术领域，特别涉及一种用于颚式破碎机的不停机间隙调整机构。The device of the invention belongs to the technical field of jaw crushers, and particularly relates to a non-stop gap adjustment mechanism for jaw crushers.
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。Jaw crusher, commonly known as jaw crusher, consists of a movable jaw plate and a fixed jaw plate to form a crushing cavity, which simulates the movement of the two jaws of animals to complete the material crushing operation. It is widely used in medium-size crushing of various ores and bulk materials in mining, smelting, building materials, highway, railway, water conservancy and chemical industries. Usually, the movable jaw plate is driven by the rotating shaft eccentrically set on the flywheel for crushing.
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，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。Because the jaw crusher needs to crush various materials, the actual use situation is more complicated. After a long time of work, the fixed jaw plate is prone to wear and tear, and the thickness of the fixed jaw plate is reduced, so that the crushed materials cannot be crushed by the crusher. To achieve the required size, it is usually necessary to place a spacer between the adjustment seat of the movable jaw plate and the frame to adjust the distance between the adjustment seat and the frame. By changing the number of spacers, the movable jaw plate and the fixed jaw plate can be adjusted. However, when adjusting the distance between the movable jaw and the fixed jaw, in order to ensure the safety of the operator, it is necessary to disconnect the power supply of the crusher. It needs to be replaced after it is stopped, and it is necessary to wait for the flywheel with a larger mass to stop rotating after the shutdown, which is time-consuming, has low processing efficiency, and is inconvenient to replace. The existing technology has areas that can be improved.
