Automatic material-probing instrument of oil shale retort

The invention discloses an automatic material-probing instrument of an oil shale retort, the automatic material-probing instrument uses a steel wire rope connecting probe to probe materials, and the automatic control is realized through a PLC and a plurality of sensors. The PLC controls the start, the stop, the positive rotation and the negative rotation of a steel wire rope hoist motor by judging the states of the various sensors and combining position data of the probe. The device adopts the full sealed material probing method, the method can improve the regional environmental quality of the device, reduce the labor intensity of operators, be well matched with a discharge system and further improve the yield of shale oil, more importantly, the method can reduce the leakage of oil gas, greatly reduce the damage to the environment and realize environment-friendly enterprises.
