Bucket tooth falling monitoring device and excavator
The invention discloses a bucket tooth falling-off monitoring device and an excavator, and belongs to the technical field of mining machinery, the bucket tooth falling-off monitoring device comprises a monitoring mechanism, the monitoring mechanism comprises a monitoring assembly and a magnet assembly, a first connecting position is arranged in a containing groove, and a second connecting position is arranged at the position, right opposite to the first connecting position, of the head of a tooth holder; one of the first connecting position and the second connecting position is provided with a monitoring assembly, the other connecting position is provided with a magnet assembly, the distance between the monitoring assembly and the magnet assembly is a first distance value, and the monitoring assembly judges the first distance value by judging the change of the oscillation amplitude of an LRC circuit of the monitoring assembly caused by the change of the distance between the magnet assembly and the monitoring assembly; and when the oscillation amplitude is higher than a threshold value, the monitoring assembly generates prompt information. The excavator is provided with the bucket tooth falling monitoring device. Through cooperation of the detection assembly and the magnet assembly, the monitoring effect is optimized, and the monitoring distance of the monitoring assembly is increased.
本发明公开了一种斗齿脱落监测装置及挖掘机，其属于采矿机械技术领域，斗齿脱落监测装置包括监测机构，其中，监测机构包括监测组件和磁体组件，容置槽内设置有第一连接位，齿座的头部正对第一连接位设置有第二连接位，第一连接位和第二连接位中，其中一个上设置有监测组件，另一个上设置有磁体组件，监测组件与磁体组件的间距为第一距离值，监测组件通过判断磁体组件与监测组件的距离变化引起监测组件LRC电路的振荡幅度变化来判断第一距离值，从而判断斗齿是否从齿座上脱落，当振荡幅度高于阈值时，监测组件生成提示信息。挖掘机配置有上述的斗齿脱落监测装置。通过检测组件和磁体组件的配合，优化了监测效果，提高了监测组件的监测距离。
