Automatic material probing apparatus of bituminous shale retort furnace

The utility model discloses an automatic material probing apparatus of bituminous shale retort furnace, which probes materials through connecting a probe by a steel wire, and realizes the automatic control through a PLC and a plurality of sensors, wherein the PLC controls the starting, the stopping and the positive and the negative rotations of a steel wire hoisting motor through judging the state of each sensor and combining the location data of the probe. The set of the device adopts the fully-closed material probing method, the method can improve the regional environment quality of the device, reduces the labor intensity of operating personnel, and matches a feeding system better, thereby improving the yield of shale oil, most importantly, reducing the outward leaking of oil mash gas, greatly reducing the harm to environment, and realizing environment-friendly enterprises.
