Detection system for discharge port of single-cylinder hydraulic cone crusher

The utility model discloses a detection system for a discharge port of a single-cylinder hydraulic cone crusher, which comprises a spring dynamometer mounted at the top end of a fixed cone in an embedded manner and a pull rope mounted at the top end of a movable cone assembly, one end of the pull rope is hinged with the spring dynamometer, and the discharge port is formed between the bottom end of the movable cone assembly and the bottom end of the fixed cone. An end plate is installed on the top surface of the movable cone assembly, a top groove is formed in the top surface of the end plate, and a base plate is fixed to the inner side of the top groove. A pull rope with reliable strength is mounted at the top end of a movable cone assembly, and a spring dynamometer hinged to the pull rope is mounted at the top end of a fixed cone, so that when the movable cone assembly ascends and descends, the pull rope can be driven to stretch the spring dynamometer, and the tension value of the movable cone assembly can b
