The multi - functional combined position - detecting oil needle includes an electronic magnetic needle 01, a measuring rod 02, a bearing seat 03, and an information exchange device 04. The bearing seat 03 is installed at the three - axis position of the reduction gearbox of the shearer boom, and the measuring rod 02 is installed on the bearing seat 03. The electronic magnetic needle 01 is arranged inside the measuring rod 02, and one end of it is placed in the oil inside the reduction gearbox, and the other end is connected to the information exchange device 04 to send the detected liquid level information to an external device (such as a host computer, etc.).

[0038] Based on this structure, by placing the electronic magnetic needle and the measuring rod at the three - axis position of the reduction gearbox of the shearer boom, and making the other end of the electronic magnetic needle placed in the oil, the liquid level of the oil in the reduction gearbox is collected, and is sent to the host computer in real time through the information exchange device, so as to measure the oil level of the oil in the reduction gearbox of the shearer boom and continuously collect and output the signal of the oil, realizing the situation of observing the oil level of the reduction gearbox of the boom without stopping the machine.

[0039] In a specific embodiment, the electronic magnetic needle 01 and the measuring rod 02 are arranged in pairs to detect the liquid level of the oil in the speed reducer. Specifically, the axial surface of the electronic magnetic needle 01 is covered with a pressure sensing unit to detect the oil in the speed reducer through the pressure sensing unit. In addition, a scale line is provided on the axial surface of the measuring rod 02. The pressure sensing unit obtains a detection result signal based on the scale line and transmits the detection result signal to the information exchange device 04, so as to obtain the liquid level information of the oil in the speed reducer based on the detection result signal.

The electronic magnetic needle 01 is installed on the side wall of the cavity 0203 of the measuring rod 02, so that the rod body 0202 of the measuring rod 02 plays a role in protecting the electronic magnetic needle 01.

[0041] Based on this structure, the lengths of the electronic magnetic needle 01 and the measuring rod 02 are set to match the depth of the speed reducer of the shearer rocker arm, so as to realize the full-precision measurement and detection of the liquid level change.

[0042] In a specific embodiment, the bearing seat 03 is a plug-type bearing seat, and is thus installed in the screw hole at the three-axis of the speed reducer through a threaded fastening structure, realizing stable installation and being convenient for disassembly and replacement at the same time.
