Arrangement structure of proximity switch for chain breakage protection of submerged chain conveyor

An arrangement structure of a proximity switch for chain breakage protection of a submerged chain conveyor comprises a rotating shaft arranged near a downlink chain, the rotating shaft is used for being installed on a submerged chain conveyor shell, one end of the rotating shaft is provided with a trigger rod, the other end of the rotating shaft is provided with a monitored rod, the trigger rod is located on the inner side of the submerged chain conveyor shell, and the monitored rod is located outside the submerged chain conveyor shell; the monitored rod is used for being detected by the proximity switch, and the trigger rod is used for being triggered by a scraper of the submerged chain conveyor. According to the chain breakage protection device, the problem of misoperation of the proximity switch when the chain wheel deviates transversely can be solved, and chain breakage protection of the submerged chain conveyor is more accurate. 一种捞渣机断链保护用接近开关的布置结构，包括布置在下行链条附近的转轴，转轴用于安装在捞渣机外壳上，转轴一端设有触发杆，转轴另一端设置有被监测杆，触发杆位
