Drilling type coal pile middle detection device

The invention relates to the technical field of coal pile sampling, in particular to a drilling type coal pile middle detection device. According to the drilling type coal pile middle detection device, the sensing element can be protected when the middle of a coal pile is drilled, extrusion friction damage between the sensing element and coal briquettes of the coal pile is avoided, and the service life of the sensing element is prolonged. A drilling type coal pile middle detection device comprises a movable frame, a motor and the like, and the motor is connected to the front side of the left portion of the movable frame. The first connecting frame is limited to stop moving, the shielding cover is controlled to stop moving along with the drill bit, the drill bit continues to move along with the sliding pipe to stretch the spring, and the temperature sensor is brought out and exposed to the designated position after drilling, so that a sensing element can be protected when the middle of a coal pile is drilled;
