Embodiment Construction
[0014] Assuming that the installation distance between the two guide shoes of the shearer is L, within the length of L, there are N pin racks (including the pin racks at both ends in contact with the guide shoes).
[0015] Within the entire length of the conveyor, sensor units are respectively installed on the upper surface of each pin rack, and the two sensor units are arranged symmetrically along the axis of the pin axis. The one on the side is called the right sensor unit.
[0016] The left sensor unit and the right sensor unit are mounted on the upper surface of the pin rack. There are two grooves on the upper surface of each pin rack (that is, the upper surface of the rails on both sides of the pin rack). There are left sensor unit and right sensor unit, and the wireless pressure sensor is installed in the sensor quick changer.
[0017] There are several threaded holes on the ring-shaped surface of the two grooved step holes on the upper surface of each pin rack. The th...
